DEVICE FOR REGULATING THE WORK OF THE STRAIGHT-THROUGH GAS-FIRED WATER HEATER Russian patent published in 2018 - IPC F24H9/20 

FIELD: processes automation devices.

SUBSTANCE: invention relates to the automation of flow-through communal-general and gas heat engineering facilities. Technical result is achieved in the claimed device for regulating the straight-through gas-fired water heater, (3), which comprises the valve (4), which is spring loaded by means of the spring (1), which supplies gas to the burner (2), the valve is performed using the adjusting rod (4), which is connected with the mobile link of the water unit (7) that is made in the form of the elastic membrane (8), which is fastened to the plate (9) in the presence of water flow in the pipeline (5) of the water heater, (which is determined by the opening of the shut-off valve (6)), and the throttling device is the small diameter through opening (10), which is made in the tray (9) of the elastic membrane (8), in which there is the enlarged opening (11), which is concentrically located in relation to the throttle opening (10) in the tray 9) connecting the sub-membrane space (12), which is connected to the supply pipeline (13) of cold tap water, and the above-membrane space (14), which is connected to the inlet of the water heater pipeline (15) and to the heat exchanger (16), in which cold water is heated from the gas burner (2), which is ignited with the spark plug (22) in case when the gas valve (17) is open, and in parallel to the throttle opening (10), which is located in the tray (9), in the housing (18) of the device for regulating the operation of the straight-through gas-fired water heater, the controlled bypass (19) is mounted, which provides for the increased flow capacity in order to increase the flow rate of cold water and provides for regulating the flow rate of water through the supply pipe (13) while turning the handle (20), changing the internal cross-section (21) of the bypass (19) from the shutdown of the water flow rate to the maximum value, while the noise level of the flowing water does not exceed the permissible sanitary norms.

EFFECT: technical result of the claimed invention is the creation of a new device for regulating the straight-through gas-fired water heater, which has small dimensions and mass, technological simplicity, increased reliability in operation, and increased throughput capability of the new device flow rate without exceeding the permissible sanitary noise standards.
