The invention relates to hot water, in particular to means of regulating the temperature in the network of hot water.

The aim of the invention is to improve the reliability of the controller.

The drawing schematically shows the proposed temperature controller direct action for hot water systems.

The regulator contains the first chamber 1 with two nozzles 2 and 3, the flow line

4 hot water, return line

5 a heating system, a second chamber 6 connected to a straight line 7 of the heating network, a regulator located in the chamber 6 and made in the form of a nozzle 8 and a throttle needle 9 connected to a thermosilphone 10 fitted with an adjusting element 11, a third chamber 12 whose input 13 is connected pipe 14 with the supply line 4 hot water, and the output 15 through pipe 16 is connected to the first chamber 1;

The temperature controller operates as follows.

Water from the direct line 7 of the heating network enters the second chamber 6, from where it flows through the nozzle 8 into the first chamber 1 and then through the nozzle 2 into the flow line 4 of the hot water supply system. At the same time, under the influence of the ejector jet flowing out of the nozzle 8, water from the return line 5 of the heating system through pipe 3, chamber 1 and pipe 2 also enters the flow line 4 of the hot water system, mixing with water from the direct line 7 of the heating system. In addition, under the influence of the ejection of the jet flowing from the nozzle 8, the water from the outlet 15 of the third chamber 12 enters the chamber 1, and water from the hot water supply line 4 flows to the inlet 13 of which. With this water,

flowing through the third chamber 12, washes the thermo-bellows 10, the temperature of which consequently corresponds to the temperature of the water flowing through the chamber 12.

5 As a result, when the temperature in the flow line 4 changes, the temperature of the thermophone 10 in chamber 12 will change accordingly, resulting in temperature distortions of the thermophone 10, movement of the associated throttle needle 9 relative to the nozzle 8, change in the flow cross section of the latter and, consequently, flow water entering the mix from the direct heat network through the second chamber 6.

As a result of this implementation in the hot water system is automatically set to a predetermined temperature, the set value of which is set by regulating the element 11, and thus ensures reliable operation of the controller.
