Abstract

The invention provides automatic regulation of heating systems without disturbing the hydraulic modes of the heat network. The purpose of the invention is to improve the performance of automated heating systems. The device includes a regulator 3, a heat exchanger 4, an injector 5, a check valve 6. To reduce the heat capacity of the system, the regulator 3 closes and the coolant enters the heating system cooled in the heat exchanger 4. With the valve 3 open, the heating water does not enter the heat exchanger 4 as a non-return valve 3, it counteracts the vacuum created by the injector 5. 1 Il. (L

The invention relates to heating equipment, namely to thermal inputs of heating systems connected to heat networks, and may not be used in the construction and overhaul of residential and public buildings equipped with automatic water heating systems.

The aim of the invention is to increase the efficiency and economy of the heating system.

The drawing schematically shows the proposed device ..

The device for regulating the heat power of the heating system consists of the heating system 1 55 connected to the centralized heat supply source 2, the control device including the regulating member 3, the heat exchanger 4j injector 5 and the check valve 6.

When the heating system is operating in the mode of full utilization of thermal power, the regulator 3 is 1dit in the open position and the entire supply of heat carrier from the heat source 2 ipowal moves past the heat exchanger 4 and enters the nozzle kPi | of the injector 5, creating a rarefaction | In the heating circuit of the heat exchanger | 4 and in the dilution chamber (shown in {circle form), the heating water from the vacuum chamber of the injector 5 S heat exchanger 4 is prevented from entering the heating water and the water circulating in the opposite direction {opposite 6, mounted with the possibility | moving NOSTA: water therethrough and tol- | to a direction from the heat exchanger 4 to the supply line.

If it is necessary to reduce the heat output of the heating system, the valve of the regulator 3 closes, as a result of which the flow is supplied

The heat transfer medium is throttled and the pressure at the inset of the pipeline with the non-return valve installed on it decreases. After the valve is closed by a certain amount, this pressure becomes less than the pressure in the vacuum chamber of the injector 55, as a result of which the flow coolant through this chamber begins to flow into the heating circuit of the heat exchanger 4 and then through the check valve 6 into the heating system 1. At the same time, the temperature of the water in the supply pipe decreases as a result of the heat exchange with the return heat carrier, which leads to a decrease in the thermal heating system at constant flow rates of water in the system and in the heating network.
