(54) HEATING DEVICE

one

The invention relates to devices for space heating, in particular to heaters with an intermediate coolant.

According to the main author. St. No. 561845 is known for a heating device containing a hermetic case filled partially with heat-transfer fluid, in which tubular heaters connected to the heating network are immersed. In this case, the instrument case is divided into two compartments by a horizontal partition placed above the heaters, equipped with a thermostating valve, made in the form of a locking member connected by a stem with a flexible membrane fixed in the bottom of the case, and bypass valve, the end of which is located below the heaters.

The disadvantage of this device is the inability to automatically maintain the set air temperature in the room.

The aim of the invention is to automatically maintain the set temperature.

The goal is achieved by the fact that the device additionally contains a regulating screw, a spring element and a regulator.

temperature, the last of the KOTOpijix vol. in the form of a hermetic sealant with a gauge vessel with a coarse L-shaped branch, fitted with a bellows at the end, adjacent to

the adjusting screw and one end of the spring element, the second end of which is connected to the membrane fixed in the bottom of the housing, and the temperature controller is provided with a heat shield and the package is parallel to the x planar ribs mounted on

tubular branch placed between the vessel and the body.

The drawing shows the device in longitudinal section.

The drift device comprises a housing 1, partially filled with a heat-transfer fluid, in which tubular heaters 2 are connected, which are connected to a heating network. A horizontal partition 3 is located above the tubular heaters 2. The dividing body 1 is divided into two compartments. The partition 3 is equipped with a thermostatic cylinder chapan, made in the form of a shut-off 4, connected by a rod 5 with a flexible membrane 6 placed in the bottom of the body K and a by-pass nozzle 7. Under the shut-off organ 4 in the partition 3, the opening of the 8. thermal fluid of the intermediate heat carrier is made The housing 1 is equipped with a valve 9. The device additionally contains a regulating screw 10, a spring element 11 and a temperature controller, made in the form of an armored liquid with pressure gauge liquid vessel 12 with a tubular L-shaped and twisting 13, fitted on a bellows 14. The end of the bellows 14 is adjacent to the adjusting screw 10 and one end of the spring element And, the second end of which is connected to the membrane 6. The temperature regulator is provided with a heat shield in the form of a package of parallel flat ribs 15 mounted on a tubular branch 13 between the vessel 12 and the housing 1. The heater operates as follows. The tubular heater m 2 moves the heat carrier. b, recoil heat to the intermediate coolant and vaporize it. A pair of intermediate coolant through the hole 8 enters the upper compartment of the housing 1 and, condensing, give off heat to the heated room. Steam condensate through pipe 7 flows into the lower compartment of housing 1 and evaporates again. If the pressure in the heater exceeds the pressure in the room, then the membrane 6 is flexible and is extruded to the outside and the valve 4 is closed by means of p1T () ka 5. The hydraulic resistance to the steam flow will increase and the pressure in the lower compartment will increase. In connection with this, a part of the intermediate tag of the bearer through pipe 7 is extruded into. upper compartment A portion of the surface of the tubular heaters 2 is exposed, the heat removal from the heating network is reduced, and the pressure inside the device returns to acceptable limits. Similarly, the process of automatic maintenance of the air temperature in the pump, enim, proceeds. Since npvs6op 1) is designed in such a way that under normal conditions the pressure in it is below atmospheric, the membrane 6 all the time pushes the rod 5 upward toward the larger opening of valve 4. Screw end 10 is always pressed against the end of the bellows 14. Therefore, if the temperature in the room exceeds the set level, the liquid in vessel 12 will become loose and the bellows 10 will move the shafts 5 down, thereby closing the valve 4. If the temperature in the room decreases, the bellows 14 will shorten and the heat output from the device will increase. The thermostat vessel 12 is completely filled with a gauge fluid and therefore the pressure drop force on the membrane 6 will only ensure the screw 10 is pressed against the bellows 14. This force (.the maximum on the order of 5OH) cannot cause even a noticeable compression of the fluid, which would change supported by the temperature controller. By turning the screw 10, it is possible to change the temperature maintained by the device along the displacement (when the screw 10 is moved upwards, this temperature decreases, and when it moves downwards it rises). The stack of ribs 15 zaps the vessel 12 from the heat flow of the heater and allows the temperature of the liquid in the vessel 10 to be maintained at the level of the ambient air temperature. Such an embodiment of the device will allow maintaining the temperature of the air in the room at the same level, excluding overheating. The invention of the heater on the author. St. 561845, characterized in that, in order to automatically maintain a predetermined temperature, it further comprises a regulating screw, a spring element and a temperature controller, the latter of which is designed as a sealed vessel filled with a manometric liquid, with a tubular L-shaped branch equipped with a bellows at the end, adjacent end to the adjusting screw and one end of the spring element, the second end of which is connected to a membrane fixed in the bottom of the housing. 2. The apparatus according to claim, characterized in that the temperature controller is provided with a heat shield in the form of a pack of parallel flat ribs mounted on a tubular branch and placed between the vessel and the body.
