Description

The utility model relates to water supply, in particular to water supply systems, and is intended to account for the flow of water when it is supplied to the consumer from the main water supply network.

A device is known for measuring the amount of consumed water in cold and hot water supply networks of the population (see State Unitary Enterprise Vodokanal of St. Petersburg. Schematic of the water meter assembly, album of diagrams, diagram CIRV 02A.00.00.00, sheet 38). It includes a pipeline section with a water measuring device and is made in the form of a measuring circuit with the possibility of connection, on the one hand, to the main water supply network, and on the other, to the subscriber water network. As part of this device there are series-connected elements. Their list in the direction of the flow of water includes: a water measuring device with nozzles connected to it and two locking devices located on both sides of the water measuring device. Next, there is a water purification filter installed in front of the water measuring device. On the side of the main water supply network, at least one adapter elbow and at least one adapter are placed, the inlet of which corresponds to the diameter of the pipes of the main water supply network, and the outlet has a smaller diameter corresponding to the diameter of the connecting pipes of the water measuring device.

This technical solution is chosen as a prototype, because it contains the largest number of essential features that match the claimed utility model. In addition, the prototype has wide practical application.

However, the prototype has significant disadvantages. This is the need for individual adjustment of its elements for different sections of the water supply network, which often requires the use of turning and welding (manufacturing elements for the appropriate size of the corresponding section of the water supply network). Therefore, the time taken to install such a device increases.

In addition, this known device for measuring the amount of water consumed in cold and hot water supply networks of the population, the connection elements are made rigid. This creates additional difficulties during its installation, since it is necessary to connect sections of the water supply network located at different distances from each other and with the displacements of their longitudinal axes relative to each other.

Moreover, the measurements made using the known device have low accuracy, which is due to the occurrence of turbulent water flows on the measured section of the water supply network, as well as the difficulty in matching the passage openings between the components of the device and its input and output connections to the water supply network.

The objective of this utility model is to achieve the following technical results:

- to give the device individual and universal properties, which will expand its application for different water consumers due to the possibility of integration into various water mains (networks);

- reduce the time to install it in any connection of the main and subscriber water networks;

- to improve the accuracy of accounting for water flow by reducing the degree of turbulence of the fluid flow in front of the water measuring device.

The problem is solved as follows. A known device for measuring the amount of water consumed in cold and hot water supply networks of a population, comprising a pipeline section adapted to be connected on one side to a main water supply network, and on the other to a subscriber water network having a locking device, a water meter with a meter installed behind it, a nozzle and a second locking device, ACCORDING to the present utility model, between the first locking device and the water measuring device with a meter, a fil a tr-jet straightener with multi-pass connecting flanges at the inlet and outlet and made in the form of a combined device combining a coarse filter and a jet straightener having a diffuser and a confuser with at least four guides located between them, while the locking devices have different-pass connecting flanges on inlet and outlet, and the pipe is made universal and from an elastic material with the ability to change its length.

The applicant conducted a patent search, which showed that the claimed combination of essential features is not known. Therefore, the proposed utility model can be considered new.

This new technical solution gives the device for measuring the amount of water consumed in the cold and hot water supply networks of the population the versatility in including it in any section of the main water supply connection to the subscriber water supply network while improving the accuracy of accounting for water consumption and at the same time individuality in application for different consumers.

Universality and individuality are achieved by the fact that the pipe is made of elastic material and with the possibility of changing its length, and the accuracy of accounting for water flow is achieved by introducing a filter-jet straightener, which dampens the turbulence of the water flow, and by ensuring the necessary conditions at the inlet of the water measuring device with a meter that records water consumption. In addition, individuality is achieved by the fact that when installing the proposed device in the highway, its pipe is adjusted to the required distance between the connected sections of the highway. Moreover, after the mentioned fitting, the proposed device cannot be reinstalled on a new section of the highway without changing the length of the universal pipe.

The essence of the claimed utility model is illustrated in the drawing (figure 1), which gives a General view of the proposed device and its following positions:

1. pipeline section;

2. output of the main pipeline network;

3. The first locking device with multi-pass connecting flanges at the inlet and outlet;

4. filter-jet straightener with multi-pass connecting flanges at the inlet and outlet;

5. water measuring device with a counter;

6. universal pipe;

7. a second locking device with multi-pass connecting flanges at the inlet and outlet;

8. the entrance of the subscriber water network.

The proposed device for measuring the amount of water consumed in the cold and hot water supply networks of the population is used to account for the consumed water according to the readings of measuring instruments and to provide the possibility of remote transmission of information measured by water meters and flow meters - counters Du 20, 25, 32, 40, 50, 80, 100 , 150, 200 mm, having a pulse output or radio modem (not shown in the drawing). This device contains a pipeline section 1. It is made with the possibility of connection from one side to the main water supply network, i.e. to its exit 2, on the other - to the subscriber water network, i.e. to its entrance 8 and has a first locking device 3. The second locking device 7 is almost similar. These devices have different-way connecting flanges (not shown in the drawing) at the inlet of DN 80, 100, 150 and 200 mm and the outlet of DN 50, 80, 100 150 mm locking device for installation on pipelines DN 80, 100, 150 and 200 mm. Between the first locking device 3 and the water measuring device 5 with a counter, a filter-jet straightener 4 with different connecting flanges is introduced at the inlet of DN50 mm and the outlet of DN 20, 25, 32, 40 mm (they play the role of a transition from the diameter of the output flange of the locking device 50 mm to the connecting flange measuring device DN 20, 25, 32. 40 mm) (not shown in the drawing).

The filter-rectifier 4 is a combined device that combines:

The coarse filter (not shown in the drawing), which allows you to protect the measuring device from breakdowns - in the water meter device 5 with a counter and prevents clogging of the internal water supply system.

A flow straightener that allows you to create the flow rate diagram that is required for the measuring device. It is formed by a diffuser and a confuser and four guides located between them (not shown in the drawing), which prevent the flow from swirling.

This filter on the flanges (not shown) can be provided with special grooves for the use of O-rings. This ensures a stable seal and prevents the edges of the gaskets from getting into the water stream. A threaded device is provided in the upper part of the filter cartridge (and it is included in the filter-jet straightener) for monitoring technological parameters: pressure and temperature (not shown in the drawing).

After the water-measuring device 5 with a counter, a universal pipe 6 is installed. It is made of an elastic material with the possibility of changing its length, which allows it to be cut in place without breaking the tight connection with the water supply network. Elasticity makes it possible to choose not the alignment in the connected water pipes, but the change in length - to choose the scatter in the distances between them.

It should be noted that the universal pipe 6 can be:

- with equal bore connecting flanges at the inlet and outlet of DN 50, 50, 100, 150, 200 mm for connecting the measuring complex to the internal water supply system;

- with multi-bore connecting flanges at the inlet of DN 20, 25, 32, 40 mm for connecting to the measuring device and a connecting flange at the outlet of DN 50 mm for connecting to the object’s internal water supply system. Universal pipe 6 consists of:

- Inlet flange device DN 20, 25, 32, 40, 50, 80, 100, 150, 200 mm and the corresponding pipe segment DN 20, 25, 32, 40, 50, 80, 100, 150, 200 mm of the required length, providing straight section of at least 3 Du and containing a drain cock.

- The output flange device DN 50, 80, 100, 150, 200 mm with a collet clamp.

The proposed device for measuring the amount of water consumed in the cold and hot water supply networks of the population is installed at the interface between the internal and external water supply networks. It is detailed and functionally disclosed in the drawing and in the above description. The operation of such a device is traditional and, in general, it can be stated as follows:

Water comes from the pipe of the main water supply network and passes into the previously mentioned devices connected in series and enters the subscriber water supply network. In this case, the water may be cold or hot. From this, the principle of operation of the proposed device does not change.

The locking device with multi-pass connecting flanges allows to exclude cast-iron or steel narrowing from the composition of the measuring complex.

The filter-jet straightener allows you to create the diagram of flow velocities required for the measuring device (water meter device with a counter) due to the diffuser and confuser and four guides located between them, which prevent the flow from twisting.

The water meter device with its meter captures and provides the ability to remotely transmit information about the amount of cold and hot water.

The universal nozzle provides a straight section equal to at least 3 Du and ensures the connection of the measuring complex with the internal water supply system.

Thus, the proposed model has the following advantages over existing water supply schemes of a similar purpose:

- Reduce the number of flange connections.

- To exclude steel pipes from the structure of such a device.

- To compensate for the misalignment between the output inlet flange and the inlet flange of the internal water supply system and the distance spread.

- Form the necessary diagram of flow rates through the use of a filter-jet straightener, rather than a steel pipe, and increase the measurement accuracy.

- Reduce the labor costs of installing a device for measuring the amount of water consumed in the cold and hot water supply networks of the population.
