Valves in water supply tanks for hot water boilers

1 is an exploded perspective view of the present invention.

Figure 2 is a longitudinal cross-sectional view of the use state of the present invention.

The valve is installed on the upper part of the small hot water boiler of the present invention and inserted into the water inlet of the water supply tank to make up for the lack of water in the boiler. It is a device related to the device.

Conventionally, a hot water pump or a chuck valve is introduced to the water supply pipe in one direction only. However, since there is no valve device installed on the return pipe side, the water supply pipe of the hot water boiler serving as the water inlet and the water inlet is turned around. The water returned to the water supply tank is suppressed by the water pressure in the water supply tank, and circulation may not be smooth. Sometimes, if the heat of the hole is strong, the pressure of the water coming out of the circulation pipe becomes too strong, and the defect flowing through the water supply tank overflows. there was.

When the water in the circulation pipe is returned to the water supply tank without being completely enclosed according to the present invention, the water can be smoothly circulated without receiving the water pressure in the water supply tank, and at the same time, the sudden increase in pressure is relieved so that the water does not overflow into the water supply tank. As the simplest device in the premises, it is possible to insert a valve that is easy to manufacture, assemble and repair.

Slightly narrowed upwards to form a valve cylinder (1) having a periphery (1 ') in the upper periphery and a constant hole (2) in the center, and several struts (5) protruding in the upper surface. Insert a valve 4 having a diameter slightly smaller than the inner diameter of 1) so that a slight gap A is formed between the inner circumferential wall of the valve cylinder 1 and the valve 4, and to the bottom surface of the valve cylinder 1. The bottom stopper 6 in which the flat edge 6 'and the sewage hole 7 are drilled on the upper periphery, the bottom wheel 6 of the lower periphery of the valve barrel 1 and the bottom wheel of the bottom periphery of the bottom stopper 6 ) Is overlapped and then superimposed on the water inlet (10) of the water container (9).

Reference numeral 11 in the figure shows a return pipe that is the end of the circulation pipe embedded into the ondol.

The present invention as described above is made of three pieces of the valve barrel (1), the valve (4) and the bottom cap (6) as a synthetic resin, and is easy to manufacture, easy to assemble and disassemble, there is no failure, It is inserted into the inner diameter of the water inlet (10) of the water supply tank (9) and inserted into the outer pipe of the water outlet (10) connected to the return pipe (11) in the boiler is used, the effect is as follows.

The hot water lowered to the water inlet of the water supply tank 9 and heated in the boiler heats the heating device or the ondol through the circulation pipe, and returns the water to the water supply tank 9 from the return pipe 11 through the water inlet 10. Do you continue? Since the pressure in the boiler is not constant but fluctuates according to the combustion state of the hole coal, the pressure of the water rising to the return pipe 11 is also changed according to the heating temperature of the hot water, and the valve 4 moves up and down while the valve cylinder ( Continuously returning to the gap A between the inner wall of 1) and the valve 4, the air in the circulation pipe is also raised and discharged to the water supply tank 9.

Immediately after the hole is replaced, the pressure in the boiler drops rapidly, so that the water inlet of the water supply tank 9 is smoothly fed into the boiler, but the pressure is reduced by the return pipe 11, so the valve is operated by the water pressure in the water supply tank 9 at this time. (4) is lowered to close the sewage hole (7) of the valve cap (1) bottom stopper (6) so that it is sufficiently heated without circulating water in the circulation pipe, and when the thermal power of the coal fire burns, the pressure in the boiler rises. The valve 4 rises to open the return hole 7 so that the hot water is returned to the water supply tank 9, and when the water in the boiler or the water in the circulation pipe is continuously heated excessively, the valve 4 circulates at a high pressure to the return pipe 11. In this case, the valve (4) is raised above the valve (1), but the water and air returned between the gap (A) and the support (5) of the valve (4) while raising the pressure once rises to constant Return to the water tank (1) to The pressure will be no flow of water is discharged or overflowing the upper end blocked by the valve 4 because the water reservoir (9).

And the present invention can be easily inserted into the water inlet 10 of the existing water tank (9) as a simple structure, and by inserting the valve in the water inlet (10) is bound to the water pressure in the water tank (9) Not only is it smoothly circulated without water, and water is discharged or overflowed above the water container 9 so that there is no closed end.

Claims (1)

The three pillars 5 protrude in the valve cylinder 1 having the flat lead 1 'and the constant water hole 2 formed on the upper surface thereof, and a slight gap A is formed between the valve cylinder 1 and the valve 4. In the well-known thing which inserted the valve 4 with a small diameter, the water supply tank is formed integrally with the bottom stopper 6 by which the plain lead 6 'and the sewage hole 7 were installed in the lower part of the valve cylinder 1. The valve of the water supply tank for hot water boilers subtracted in the return port 10 of (9).
