Description

The invention relates to a device according to the broader term of claim 1. One such device is already known from document EP-A-1 096 354.

According to the state of technical development, such devices are known for regulating the temperature of technical water for heat exchangers using thermostatically controlled regulators, which are used, especially for heating drinking water, primarily in smaller residential units. Devices of this type are primarily used where the heating medium is used for heating technical water and where automatic heating of the supply of that heat medium and thus the temperature of the technical water is desired.

Regulators with thermostatic management, according to the state of technical development, regulate the flow of the heat medium through heat exchangers in such a way that the technical water maintains the temperature set via the thermostat, which is mostly independent of the amount of technical water flow. When regulating the temperature, the thermostatic valve acts exclusively on the valve of the heat medium, whereby the amount of technical water flow remains unchanged.

According to the state of technical development, such devices usually work according to the following scheme of operation: When taking water, for example when the water tap is open, the technical water valve opens and cold water flows into the heat exchanger. At the same time, the valve for the heat medium is opened and the hot heat medium is poured into the heat exchanger. In this way, the technical water is heated and exits from the heat exchanger into the water tap. The temperature sensor of the thermostat is placed in that place. When the technical water coming out exceeds a certain set temperature, the valve for the heat medium is throttled or closed and the volume flow is reduced, that is, the heat medium is closed. Accordingly, less heat medium reaches the heat exchanger. However, the amount of flow of cold technical water is not reduced. Accordingly, the temperature at the outlet of the heat exchanger drops.

At the end of pouring, i.e. when closing the water tap, the valve for technical water and the valve for the heat medium are closed simultaneously.

From EP 1 096 354, for example, one such device is known, which represents a combination of a thermostatically controlled regulator and a pressure controlled regulator. The part of the device that is regulated by pressure is basically constructed similar to a commercial PM-regulator, for example from the company Redan, where both the flow of technical water and the flow of the heat medium can be regulated (adjusted) with the help of the pressure-controlled regulator. With this type of design, one valve seat is provided, which is located in the flow of the heat medium. Two valve cones act on that valve seat, on one side the valve cone of the regulator controlled by the pressure, on the other side the valve cone of the regulator controlled by the thermostat.

The purpose of the invention is to create a device of the type mentioned at the beginning, which is structurally simple and safe in operation and enables independent regulation or. regulation of technical water and heat media without mutual influence.

These goals are achieved by the characteristics of claim 1. Both regulators, and both valve cones, operate mostly completely independently of each other and in no way affect each other mechanically or in any way. The pressure-controlled regulator regulates the amount of flow of technical water and heat medium in such a way that when taking water, it allows the flow of both heat medium and the flow of technical water, and stops the flow of both heat medium and the flow of technical water when the dispensing is finished. Completely independent of that, the regulator with thermostatic control acts additionally and exclusively on the amount of flow of the heat medium or. on the valve of the heat medium and can reduce that amount of flow in case of exceeding the specified temperature of the technical water behind the heat exchanger or stop it completely by closing the valve of the heat medium. The thermostatically controlled regulator is mechanical and is not connected to the pressure controlled regulator and has no direct or indirect functional relationship with the same. The regulator with thermostatic control represents a kind of independent over-regulation of the current of the heat medium.

The device that is the subject of the invention combines the advantages of a regulator with pressure control and a regulator with thermostatic control. As a rule, thermostats react quickly and regulate the water temperature without significant delay to the desired value. Furthermore, the flow of technical water and the flow of medium water are closed by pressure-controlled regulators immediately after intake. This prevents the subsequent heating of the heated drinking water, temperature peaks no longer occur, and also acts against the possible formation of limestone on the heat exchanger or. heat exchanger.

For the purpose of separating the functions of a pressure-controlled regulator and a thermostatically controlled regulator, the features of claim 2 are advantageous.

Separation assistance is provided by requirement feature 3.

The exact regulation of technical water that absolutely corresponds to the requirements is achieved by the characteristics of requirements 4 and/or 5.

The structurally simple structure of the device is achieved by the characteristics of requirements 6 and/or 7 and/or 8.

Simplification of production and servicing is achieved when the characteristics of requirement 9 are realized.

Exact regulation is achieved if the characteristics of requirements 10 and/or 11 are realized.

The construction and mode of operation of the regulator with thermostatic control are improved by the realization of the characteristics of requirements 12 and/or 13, respectively. thus, the regulation function of the device can be improved.

The function of regulating the device or the independence of technical water management from the flow of the heat medium is supported or are provided by the characteristics of requirement 13.

A simpler construction with the possibility of a greater load of a regulator made of plastic and operating on pressure control is given by the characteristics of claim 14.

The constructive structure, both for production and for work, is simplified if the characteristics of requirement 14 are realized.

The invention further relates to any heating body heat exchanger or comparable device, which is provided with a device based on the invention.

In the following text, the invention is explained in more detail based on an example of implementation:

Figure 1 shows a device according to the invention from the side.

Figure 2 shows the device with a top view.

Figure 3 shows a section through the device with the technical water valve closed and the heat medium valve closed.

Figure 4 shows a section through the device with the technical water valve open and the heat medium valve open.

Figure 5 shows a section through the device with the technical water valve open and the heat medium valve closed.

Figure 1 shows a device that includes regulator 1 with pressure control and regulator 4 with thermostatic control. The left part of the device has a basic structure made similar to the well-known PM-regulator from Redan<®> from technological development. The device has part 3 for technical water in the left zone and in its middle zone part 2 for district heating. The regulator with thermostatic control 4 is located on the far right, directly next to part 2 for district heating and is mechanically connected to it or. stands in a functional relationship with him. An intermediate element 50 is placed between the part with remote heating 2 and the regulator with thermostatic control 4.

In the part for technical water 3, one supply pipe extension 9 for supplying technical water 9 and one drain pipe extension 10 for draining technical water are provided. In this way, technical water can, as shown by the arrows in the drawing, come from the water network (supply) enter through the technical water inlet 9, and leave the device through the technical water outlet 10 in the direction of the heat exchanger, which is not represented in the drawing.

The right-directly connected part for district heating 2 also includes one pipe extension for the inflow of the heat medium 7 and one pipe extension for the drain of the heat medium 8. In this way, the heat medium 18 can, starting from the supply line of the district heating via the heat exchanger and the supply of the heat medium 7, not shown, flow into the device and leave it through the drain of the heat medium 8 in the direction of the return line of the district heating.

Figure 2 shows a top view of the device of the invention.

In the subject form of the device, the pipe extensions of the technical water supply 9 and the technical water drain 10 and the heat medium supply 7 and the heat medium drain 8 are placed in relation to the central central pipe axially shifted by 180°. With alternative forms of execution, it is also possible to direct the pipe extensions at right angles to each other.

The regulator with thermostatic control 4 includes an adjustable element with a temperature probe 5, which registers the temperature of technical water. In principle, in the case of regulators with thermostatic control 4, it can be any type of regulator with thermostatic control, for example, electric regulators are also considered.

Regulator 4 with thermostatic control produces resp. causes an adjustment force that can act on or close the valve 12a, 12b that regulates the flow of the heat medium. A detailed view of the thermostatically controlled valve 4 can be seen in Figure 3, which we will return to in more detail later.

Figure 3 shows the device schematically in a cross-section. According to Figure 3, all the valves of the device are in the closed position, so that neither the technical water 19 nor the heat medium 18 can flow. The valves take this closed position when no water is taken from the outlet for technical water 10.

In the part of the technical water device 3 through which the technical water 19 flows, a technical water valve 13a, 13b is installed, which includes a rotating part for closing the technical water valve 13a and the seat of the technical water valve 13b. The closing part of the technical water valve 13a can be made as a piston, as a cone, as a latch or as a valve and must be suitable to regulate the technical water and in particular to stop it.

The part for closing the technical water valve 13a is prestressed by a spiral pressure spring 14, which is placed inside the part for closing the technical water valve 13a or. the seat of the valve for technical water 13b around the conical lever 11. The spring 14 produces a force which is directed to the left in Figure 3 in the closing direction of the valve for technical water 13a, 13b, and thus attracts the closing part of the valve for the heat medium 12a over the conical lever 11 in the direction of the seat of the valve of the heat medium 12b and thus closes the valve of the heat medium 12a, 12b. The spring 14 thus acts against the force produced by the pressure-controlled regulator 1 and the spring 35 and closes when the pressure of the pressure-controlled regulator 1 decreases, both the technical water valve 13a, 13b and the heat medium valve 12a, 12b via the corresponding closing parts 12a, 13a.

The part for closing the valve 13a is shown in Figure 3 in its maximum left position and in that position it closes the flow of technical water 19. In practice, it is possible that a certain amount of technical water leaks out; such leakage losses play no role in the operation of the taper lever 11 .

In the valve for technical water 13a, 13b, more precisely in the seat of the valve for technical water 13b, 2 flow openings 45 are made which are opposite each other. Openings 45, especially the lower one that faces the supply 9, and is located upstream of the flow, have an elongated or. oval elongated or rectangular shape and its longitudinal direction directed transversely in relation to the conical lever 11. The openings 45 allow the flow of technical water 19 from the inlet 9 to the outlet 9 as long as the technical water valve 13a, 13b is open. The movement of the technical water valve closing part 13a to the left in the direction of the regulator 1 with pressure control closes at least the opening 45 which is located below in Figure 3. facing the inlet 9, which stops the flow of technical water 19.

The part for closing the technical water valve 13a is fixed and immovable, located or. guided on the conical rod 11, wherein the conical rod 11 with its left outer end is functionally connected to the pressure regulator 1. Such pressure-controlled regulators 1 are known from modern technology.

The conical rod 11 ends as shown in Figure 3 with its left outer end in a membrane plate (Membranteller) 16 or rests on it or. she is connected to him. Membrane thinner 6 can be just attached to the end of the conical rod 11 so that it can then be easily removed or replace. The surface of the membrane plate 16 facing the technical water valve 13a, 13b can have eight lamellas with intermediate spaces between them which are distributed along the circumference and directed radially towards the membrane valve, and these lamellas increase the strength of the membrane plate 16. The membrane plate 16 is located in one closed hollow space and divides that hollow space into two hollow parts, a right hollow zone 30 and a left hollow zone 31. Both hollow spaces are separated from each other by a membrane 32. In Figure 3, the membrane plate is on the far left or in its left end position, and the left hollow space 31 is small, while the right hollow space 30 is correspondingly large. In the technical water inflow zone 9, one opening 17 is provided, which connects the hollow zone 31 of the hollow space with the technical water supply 9.

In part 2 of the remote heating device, there is a valve 12a, 12b that regulates the flow of the heat medium 18 and which includes the movable part for closing the heat medium valve 12a and the valve seat for the heat medium 12b. The valve for the heat medium 12a, 12b in Figure 3 completely closes the flow of the heat medium 18. The closing part of the valve for the heat medium 12a can be constructed in different ways and can be made as a piston, a cone, a valve or a valve. Furthermore, an annular seal 33 is provided, which provides a suitable seal between the part for closing the valve 12a and the seat of the valve 12b.

The part for closing the valve of the heat medium 12a is driven on the conical rod 11 or. can be adjusted on it, or can be separated from it and placed relative to the longitudinal extension of the conical rod 11. The conical rod 11 passes through the valve for the heat medium 12a, 12b or the closing part of the valve for the heat medium 12a centrally, and the element 12a can slide along the conical rod 11. The closing part of the valve for the heating medium 12a is sealed with respect to the conical rod 11 with one ring seal 33'. The frictional forces between the sealing ring 33' of the elements 12a and the conical rod 11 are small.

In the area of the valve for the heat medium 12a, 12b, one additional spring 35 is placed, weaker in comparison with the spring 14. This additional spring 35 acts in the direction of opening the valve for the heat medium 12a, 12b in the opposite direction in relation to the force with which the thermostatically controlled regulator 4 acts on the closing part of the valve for the heat medium 12a. The spring 35 pushes the closing part of the heat medium valve 12a from the seat of the heat medium valve 12b. This is possible only when the part for closing the valve for the heat medium 12a or. the force of this spring 35, the pressure-controlled regulator 1 and/or the thermostatically controlled regulator do not overregulate and pull it to the left or do not push it onto the valve seat of the heat medium 12b.

The power of the additional spring 35 is less than or. negligibly small compared to the force of the spring 14.

The conical rod 11, as seen in figure 3 to 5, goes starting from the regulator 1 which controls the pressure or. from the membrane plate 16 through the valve for technical water 13a, 13b to the valve for the heat medium 12a, 12b.

Between the valve for technical water 13a, 13b and the valve for the heat medium 12a, 12b there is a sealing sleeve 15, in which the conical rod 11 is indeed sealed but is nevertheless movably mounted for axially directed movements with respect to its longitudinal axis. In this way, the conical rod 11 can perform only axially directed movements.

At the very right end of the conical rod 11, there is a stop element, for example a safety ring, which on one side touches or can rest on the closing part of the heat medium valve 12a. In this way, the part for closing the valve for the heat medium 12a when moving the conical rod 11 to the left can be caught and also pulled to the left, and when moving the conical rod 11 to the right, the part for closing the valve for the heat medium 12a can however remain in its position. The pressure-controlled regulator 1 thus acts on the heat medium valve 12a, 12b exclusively in the closing direction.

Figure 3 thus shows the position of the device, in which both the technical water valve 13a, 13b and the heat medium valve 12a, 12b are closed. The closing of the valve for the technical water 13a, 13b and the valve for the heat medium 12a, 12b in Figure 3 is done exclusively by means of the spring 14. The regulator with thermostatic control 4 does not act on the valve for the heat medium 12a, 12b or. does not touch the closing part of the heat medium valve 12a.

Figure 4 shows the device in the open flow position. Both the valve for technical water 13a, 13b and the valve for the heat medium 12a, 12b are open. One such open position of both valves 12, 13 exists when a certain minimum amount of technical water 19 is taken via the outlet for technical water 10. This can happen, for example, by opening the tap for extraction or water tap that is installed behind the heat exchanger. In this way, a lower pressure (negative pressure) is created in the drain for technical water 10 and thus in relation to the membrane 32 in the right hollow zone 30 which is connected to it. In the supply for technical water 9, which is connected to the left hollow zone 31 through the opening 17, the pressure when opening the tap is high. In this way, caused by the pressure difference, a force is created that acts against the pressure spring 14, moves the onus rod 11 to the right and opens the technical water valve 13a, 13b, in such a way that the spring 14 is compressed and the closing part of the technical water valve 13a moves to the right. In this way, the flow through the opening 45 is released. Technical water can generally flow unhindered through the technical water section 3 in the direction of the heat exchanger.

By moving the conical rod 11 to the right, the valve for the heat medium 12a, 12b is opened in such a way that the part for closing the valve of the heat medium 12a is released and the safety ring of the conical rod 11 no longer holds it in the closed position. The part for closing the valve for the heat medium 12a is pushed out of the seat of the valve for the heat medium 12b by the force of the spring 35. In this way, between the part for closing the valve for the heat medium 12a and the seat of the valve for the heat medium 12b, there is an annular gap that determines the amount of flow of the heat medium 18.

Figure 4 shows the maximum open position of both the technical water valve 13a, 13b and the heat medium valve 12a, 12b, and the maximum flow of technical water 19 and heat medium 18 is enabled.

With the end of discharge (pouring), i.e. when closing the tap for technical water, according to Figure 3, pressure equalization is established again. The stagnant pressure in the drain for technical water 10 as well as in the right hollow zone 30 increases, the membrane plate is pushed to the left. The auxiliary force of the spring 14 moves the closing part of the technical water valve 13a again to the left and the openings 45 close again. At the same time, the part for closing the valve for the heat medium 12a is also drawn to the left in the seat of the valve for the heat medium 12b, so that both the flow of technical water 19 and the flow of technical water 18 are closed again.

In Figure 5, the device is shown in a position where the technical water valve 13a, 13b is open, while the heat medium valve 12a, 12b is closed.

The closing of the valve for the heat medium 12a, 12b is done by pre-regulating or by applying pressure to the valve for the heat medium 12a, 12b by the thermostatically controlled regulator 4. It pushes the closing part of the valve of the heat medium 12a against the force of the spring 35 to the left into the seat of the valve for the heat medium 12b. The conical rod 11 and the technical water valve 13a, 13b remain unchanged in their positions.

The thermostatically controlled regulator 4 includes, as seen in Figures 3 to 5, one temperature probe or. adjustable element 5 and one intermediate piece 22, which can be adjusted by one stretchable element 24. Furthermore, one setpoint value transmitter 20 is provided. brings to the initial position that corresponds to the set value of the technical water temperature 19. The temperature probe 5 of the regulator 4, which measures the temperature of the technical water at the exit from the heat exchanger, is connected via a capillary tube 6 to the regulator 4 or, with the stretchable element 24, or. the capillary tube 6 is poured into the expandable element 24. The temperature probe 5 and the expandable element 24 work according to the tension principle and are usually filled with liquid, which for example evaporates depending on the temperature, whereby a pressure proportional to the temperature is created in the probe 5. The measured temperature determines the supply of liquid through the capillary tube 6 to the stretchable element 24 in a known manner. The position of the stretchable element 24 and thus the position of the intermediate piece 22 in relation to the rod 51 can vary, that is, it is adjustable. This can be done using the set value transmitter 20. The spring 21 cushions the stretchable element 24 in case of excessive temperatures.

Through the capillary tube 6, this pressure is converted into the regulating force of the intermediate piece 22, which acts on the valve for the heat medium 12a, 12b in the part of the 2nd heating.

If the temperature measured by the temperature sensor 5 i.e. the actual temperature value exceeds the set set temperature value, then the intermediate piece 22 moves to the left by the travel height that depends on the difference in temperature between the actual temperature value and the set temperature value. By moving the conical rod 51 to the left, the part for closing the valve of the heat medium 12a can also be moved to the left in the same direction. If the actual value of the temperature measured by the temperature sensor 5 is lower than the set temperature, then the intermediate piece 22 moves to the right by the stroke height that depends on the difference in temperature between the actual value and the set temperature value.

The device is structurally made in such a way that between the seat of the valve for the heat medium 12b and the part for closing the valve for the heat medium 12a, a range of travel is defined, i.e. certain walking (lifting) height. That lifting range defines the maximum deflection or. lifting the part for closing the valve for the heat medium 12a from the seat of the valve for the heat medium 12b. The annular gap that occurs in the open state therefore has this maximum lifting height.

If now the thermostatically controlled regulator 4 moves to the left the closing part of the valve for the heat medium 12a by the amount of that lifting height, then the valve for the heat medium 12a, 12b generally seals well and the flow of the heat medium 18 is interrupted. In this way, there is no further heating of the technical water 19. The technical water 19, which is no longer heated, continues to flow as before without reducing the volume flow, since the opening 45 is still completely open. The temperature of technical water 19 continues to decrease and the temperature probe detects a lower temperature. When the temperature reaches a certain lower limit, then the thermostatically controlled regulator 4 reacts and the adjustable element 22 moves to the right again and the valve for the heat medium 18 can flow (leak) again.

The force with which 22 or. the stretchable element 24 pushes to the left is greater than the counterforce caused by spring 35 and spring 52.

The thermostatically controlled regulator 4 thereby acts exclusively on the part for closing the valve for the heat medium 12a and moves it in relation to the longitudinal extension of the conical rod 11, whereby the conical rod 11 and the technical water valve 13a, 13b remain free from the pressure supply or. effects of the thermostatically controlled regulator 4.

According to the design shown in the figure, the thermostatically controlled regulator 4 does not act directly on the valve for the heat medium 12a, 12b, or the part for closing the valve of the heat medium 12a, but through the intermediate element 50 located between the thermostatically controlled regulator 4 and the valve for the heat medium 12a, 12b. That intermediate element 50 has a conical intermediate rod 51 directed in the extension of the conical rod 11, at the end of which, facing the valve for the heat medium 12a, 12b, at least one pressure element 52 is placed, e.g. in the shape of an average bell.

The shape of the pressure element 52 is selected so that due to its shape, only the valve for the heat medium 12a, 12b or. the part for closing the valve for the heat medium 12a but not the conical rod 11 or technical water valve 13a, 13b suffer pressure or be touched. According to Figure 3 to 5, the pressure element 52 can have at least one, and preferably three pressure pins placed along the circumference of the circle. The right end of the conical rod 11 which is further from the regulator 1 which controls the pressure is inside this circle and it is enclosed by the pressure rings.

The conical rod 11 and/or the conical intermediate rod 51 are each made of one piece. However, they can be made up of several pieces that act together axially or. which are connected to each other by forces and/or shape.

The device is primarily built (constructed) from one part, i.e. valve for technical water 13a, 13b, valve for heat medium 12a, 12b, intermediate element 50 and regulator 1 with pressure control are placed in one common one-piece housing made of metal or plastic from one part, or they are surrounded by a common one-piece housing. Accordingly, between the valves for technical water 13a, 13b, the valves for the heat medium 12a, 12b and the pressure-controlled regulator 1, there are no threads, joints or the like, which would lead to structural weakening of the device.

The device can also be made modular, where in particular the regulator 1, which manages the pressure together with part 3 for technical water, part for district heating 2 and thermostatically controlled regulator 4, can be independent modules that are connected to each other, which can be separately removed or change. The part for technical water 3 and the part for district heating 2 can, especially in the area of the sealing sleeve, be detachable or they can be compatible.
