The invention relates to automatic regulation and can be used in district heating systems, in particular, to mix hot water from a heating network with water and a return pipe from a heating system.

The purpose of the invention is to improve the accuracy of temperature control of buildings and the efficiency of the regulator,

Fig. 1 is a schematic representation of a temperature controller for a heat supply system; Fig 2 - connection of the controller to the building heating system „

The controller includes a throttle needle 1 installed in the nozzle 2 and rigidly connected to one end of the first thermosilphon 3, the second chamber 4 with the nozzle 5 for connection to the straight line of the heat network, the first mixing chamber 6 with the nozzles 7 and 8 for connection to the systems, heating and to the return pipe-pipe system; heating system; an additionally introduced third chamber 9 with a second thermosilphone 10 and two pipes P and 12, the first of which is connected, with pipe 13 to the pipe 8 second of the camera 6 for connection to the reverse heating system , and the second with the return line of the heating system, the second thermosilfon 10 on both sides is rigidly connected to the second end of the first thermosilphone 3 and to the element 14 of the task,

The temperature regulator of the building heat supply system operates as follows.

Water from the direct line of the heat network through pipe 5 enters the first chamber 4, and, after washing the first thermosilfon 3, through the nozzle 2 flows into the second chamber 6 and then through pipe 7 into the heating system. At the same time, under the action of the ejecting ability of a jet of water from the direct line of the heat network coming out of the nozzle 2, water from the return line of the heating system through pipe 12, an additional third chamber 9, washing thermosilon 10, pipe 1 and pipe 8 and pipe 8 into the second chamber 6, from where, together with the water, from the straight line of the heating network is directed to the heating system. The amount of direct heat carrier.

supplied to the heating network, is determined by the position of the regulating needle 1 in the nozzle 2, which automatically selects the thermo siphon 3 with a corrective action from the thermophone 10 depending on the temperature of the water in the return line of the heating system. 1 in the direction of the nozzle 2, reducing its cross-section, which leads to a decrease in the supply of direct coolant from the heating network to the heating system, which leads to a decrease in the degree of heating of the rooms. Similarly, when the temperature of the water and the heat network increases, the thermopath 3 is pulled and moves needle 1 towards nozzle 2, reducing the amount of direct water flowing into chamber 6. Thus, the position of needle 1 of nozzle 2 is determined by the action of both thermosilphons 3 and 10, i.e. the differential law of regulating the temperature of the direct water of the heating system is carried out with correction both by the temperature of the water in the heating network and by the temperature of the water in the reverse heating line,. with load correction, taking into account heat consumption in rooms. The setting (setting) of the regulator is determined by the position of the element of setting 14, which changes the initial position of the needle 1 in the nozzle 2.
