Abstract
The utility model provides an emptying valve of a solar water heater, which comprises a magnetic valve and an air valve. One end of the magnetic valve is connected with a water outlet of the solar water heater, and the other end of the magnetic valve is connected with a tee joint. The other end of the tee joint is connected with a water pipe, a third end of the tee joint is connected with the air valve, and the upper end of the air valve is provided with a dust cover capable of preventing dust from entering the air valve. The emptying valve of the solar water heater is installed at the water outlet of the solar water heater. When the magnetic valve is closed, the water outlet of the solar water heater stops water supply, a negative pressure is formed in a pipeline, the air valve is opened automatically, and air enters the pipeline from the air valve, thereby enabling residual water in the pipeline to be discharged completely. When the emptying valve is used again, the residual water does not need to be discharged, and hot water can flow out of the solar water heater only by opening the magnetic valve, thereby achieving readily available use and energy and water conservation and facilitating use of the hot water.
Description
Technical field
The utility model relates to a kind of solar water heater water intaking control device, particularly a kind of solar water heater emptying valve.
Background technology
In the use of solar water heater, when beginning to fetch water, what flow out is the residual water that has in the pipeline; Temperature is not high, only after after a while, could flow out hot water; Cause taking hot water inconvenience, and discharge a large amount of residual water and also be unfavorable for fwaater resources protection.
The utility model content
The technical problem that the utility model will solve is to overcome existing defective, provides to make the water emptying that remains in the pipeline, makes the instant a kind of solar water heater emptying valve got of hot water.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of solar water heater emptying valve comprises magnetic valve and air valve, and said magnetic valve one end connects the delivery port of solar water heater; The other end connects a threeway; The other end of said threeway connects water pipe, and the 3rd end of threeway connects air valve, and the air valve upper end is equipped with dust cover.
Further, described air valve is for be provided with straight up.
A kind of solar water heater emptying valve of the utility model; Be installed on solar water heater delivery port, when closing magnetic valve, the water heater delivery port stops water outlet; Form negative pressure in the pipeline; Air valve is opened automatically, and air gets into pipeline from air valve, thereby makes that residual water flows out row's light in the pipeline; When reusing, need not to arrange residual water again, open magnetic valve, hot water can flow out from water heater, realizes instant getting, and has both made things convenient for taking of hot water, realizes energy-conservation, water saving again.Dust cover can prevent that dust from getting into air valve.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of solar water heater emptying valve of the utility model.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1, magnetic valve 2 one ends connect the delivery port of solar water heater 1, and the other end connects a threeway 3; The other end of threeway 3 connects water pipe 6; The 3rd end of threeway 3 connects air valve 4, and air valve 4 is provided with straight up, and the air valve top is equipped with dust cover 5.
When closing magnetic valve 2, the delivery port of solar water heater 1 stops water outlet, forms negative pressure in the water pipe 6, and air valve 4 is opened automatically, and air gets into pipelines from air valve 4, thereby makes that residual water flows out emptying in the water pipe 6; When need reuse solar water heater,, open magnetic valve 2 because of the water of noresidue in the water pipe 6; Hot water can flow out from solar water heater 1; Realize instant getting, and need not wait cold water row light residual in the water pipe 6 just can receive hot water again, thereby make things convenient for hot water to take.
A kind of solar water heater emptying valve of the utility model had both made things convenient for taking of hot water, realized energy-conservation, water saving again, and dust cover can prevent that dust from getting into air valve.
The above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
