Abstract
The invention discloses an automatic water feeding valve of a solar water heater. When water is fed into a water tank of the solar water heater, a valve bonnet of a valve rod is pressed down, an elastic element is compressed, both a first valve and a second valve are opened, and water with pressure flows into the water tank of the solar water heater; water in an overflow water return pipe is discharged by a water outlet of the second valve; when no water flows out from the water outlet of the second valve, the valve bonnet on the valve rod is loosened, and the elastic element is restored into the original shape; the second valve is closed, the first is still kept in an open state, the water with pressure continuously flows into the water tank of the soar water heater, the water overflows from the overflow water return pipe after the water tank is filled with water, and the overflowed water flows into a membrane box through the overflow water return pipe; after the water level in the overflow water return pipe reaches a certain height, a membrane in the membrane box is pressed to be pushed out, the valve rod is pushed by an output rod connected to the membrane, and the first valve is closed to stop water feeding.
Description
Affiliated technical field the present invention relates to a kind of water-supply valve of solar water heater, especially a kind of automatic loading water in solar water heater valve.
Background technology is present; In the application of automatic loading water in solar water heater; The employing sensor that has detects the water level of water tank, and with the automatic control water feeding mode of solenoid control watering pipeline, this mode need be installed liquid level sensor on water tank; And need to give the liquid level sensor backguy, use not very convenient; The solar water heater that also has is employed in the inner ball-cock assembly that increases of water tank, the control water inlet, and after liquid level met the demands, ball-cock assembly was closed into water automatically, and this mode need increase ball-cock assembly in airtight water tank, after going wrong, keep in repair pretty troublesome; For doing the solar water heater that use at tame ten thousand families, adopting maximum at present is manually operated water feeding mode, opens water on the valve; Water in the water tank is explained on water tank and has been expired water, artificial valve-off when overflow pipe flows out; Stop to go up water, the shortcoming of this mode is to wait for that the process time of filling up water is longer, and the operator generally also will handle other thing simultaneously; Timely valve-off after usually causing the water of water tank full sometimes even forgotten valve-off, causes the unnecessary waste of water.
Summary of the invention is in order to overcome the problem that existing automatic loading water in solar water heater method exists, and the present invention provides a kind of automatic loading water in solar water heater valve, can realize the automatic loading water of solar water heater easily, and after the water of water tank was full, valve was closed automatically.
