Description

The invention relates to solar power and can be used in water heaters with accumulation of heated water.

The aim of the invention is to improve the reliability of the water heater by expanding the functions of the float valve.

FIG. 1 shows a solar water heater, a common one; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a cross-section of the FIG. I.

At the same time, the cold water through the feed pipe 1 enters the overflow pipe 9 and through the gaps the inter-solar water heater contains a feed pipe 1, a radiation receiver 2 and connected to the last ave - 5 by fins 11 of the rod 6 and a wall of the reverse and return pipes 3 and 4 inlet 9 - in the upper part 7

respectively, the storage tank, the fuel storage tank, and the flow compensated by a float valve with attached water through the outlet 19.

5 to the float to the float 6. Tank-akku-If the flow of water to the consumer is stopped, the torus is made of upper and lower legs, or is significantly reduced,

parts 7 and 8 connected by a bypass in the lower part 8 of the storage tank rises, the float 5 pops up, the rod 6 is pushed, and when the fins 11 are above the connecting zone of the supply pipe 1 to the bypass nozzle 25, 9 line 1 is terminated. At the same time, the water supply from the upper part 7 of the storage tank to its lower part 8 is stopped due to the raising of the upper end of the current w 6 above the level in the upper 30 part 7 of the storage tank.

This device allows, therefore, to increase the reliability of the heater by combining the float valve functions to regulate the flow of cold water in the upper part 7

18 and the outlet nozzle-tank-battery and heated water in its

bottom part 8.

pipe 9. The stem of the 6-float valve is installed in the bypass pipe 9 and is made hollow with lateral orifices 10 in the lower part and with external fins 11 in the upper part.

The float 5 is located in the lower part 8 of the storage tank and is equipped with a perforated apron 12, and the supply line 1 is connected to the bypass connection 9.

The rod 6 has a cavity 13 and is equipped with a bracket 14 to which a flexible nozzle 15 is attached, connected to a straight pipe 3. The battery tank is also equipped with air fans 16 and 17, an electric heater com.

Solar water heater works as follows.

The water in the receiver 2 of the radiation is heated through the direct pipeline 3 through the flexible pipe 15 to the upper part 7 of the storage tank. Part of it returns through the return pipe 4 to the radiation receiver 2, and the rest when the float 5 is lowered enters through the cavity 13 of the rod 6 and the side openings 10 to the lower part 8 of the storage tank, where it is heated to the required temperature using an electric heater 18.

At the same time, cold water through the feed pipe 1 enters the bypass pipe 9 and through the gaps between the fins 11 of the rod 6 and the wall of the bypass pipe 9 - into the upper part 7
