Abstract
The utility model discloses an automatic control valve for a solar water heater, which is provided with a valve body [1] and a control valve body [10], wherein the valve body [1] is mutually sealed and connected with the control valve body [10]. The utility model is characterized in that the valve body [1] is inlaid with a slide valve [8] of which the front end is provided with a valve opening [8] and the middle part is provided with a spring [6], and a plunger [2] is arranged in the control valve body [10]. The utility model has the advantages that when the control valve of the solar water feed system is out of control, the utility model can implement the auxiliary automatic water shutoff control, and can automatically supplement water when shortage of water occurs. If provided with other automatic control elements and devices, the automatic control valve can implement the full automatic water feed control of the solar energy, which saves water.
Description
Technical field
The utility model belongs to a kind of hydraulic pressure composition element, is specially adapted to a kind of domestic solar water heater's internally piloted valve of domestic solar water heater.
Background technology
At present in the use of family expenses solar water heater, general all storage tank by above the position, an overflow mouth of pipe is set, connect and get back to the position of supplying water to solar water heater, general in the toilet of family, minority is also arranged in the lavatory, (in addition, can also be communicated with atmosphere, so that discharge unnecessary water at any time).The relatively more easy solar water heater of this structure, that uses in vast town dweller at present is many, and in these places, exists the pressure of supply water instability, the phenomenon that some places also exist not timing to supply water.Owing to these reasons, often cause to cutting off the water in the middle of water the time on the solar water heater or hydraulic pressure is very little can't go up water (just can't supply water in the storage tank of solar water heater), and cause some users not give the solar storage water tank filling up water, also not closing the water supply valve door just is away from home and goes to work, if during this time, in case running water system supplies water again, hydraulic pressure has reached the pressure of last water, expired water on will causing in solar water heater's the storage tank, and valve does not close, and continues to make unnecessary water to flow away and cause very big waste from overflow pipe.Although the device that adopts automatically controlled automatic loading water is also arranged now,, said in the above area, it is undesired to power sometimes, also the problems referred to above can occur.And take energising in a day 24 hours, also be a waste factor.In order to overcome this problem, pass through conscientious research and thinking, and consulted relevant engineers and technicians, goal of the invention of the present utility model has been proposed, just provide a kind of domestic solar water heater's internally piloted valve.
Summary of the invention
Summary of the invention of the present utility model is a kind of domestic solar water heater's internally piloted valve that designs for the deficiency that overcomes present technology existence.This domestic solar water heater's internally piloted valve, it has valve body [1], application valve body [10], valve body [1] and mutual airtight connection of application valve body [10], it is characterized in that in valve body [1], having a front end and have the guiding valve [8] that valve opening [8] and centre have spring [6], in application valve body [10], have a plunger [2].The advantage of this control valve is conspicuous, when overflow pipe and backwater interface [3] connection, when the pressure of backwater reaches certain degree, will drive guiding valve [8] moves, thereby valve opening [9] is closed, prevented that effectively running water from continuing to continue to supply water in the storage tank of solar water heater, prevented that the thing of leaking from taking place, thereby effectively saved water.
Description of drawings
Accompanying drawing 1 is a structural front view of the present utility model, and accompanying drawing 2 is that the A of accompanying drawing 1 is to view.Sequence number in the accompanying drawing is: 1, valve body, 2, plunger, 3, the overflow pipe interface, 4, overfall, 5, the water outlet interface, 6, spring, 7, the water inlet interface, 8, guiding valve, 9, valve opening, 10, application valve body.
The specific embodiment
With reference to accompanying drawing, domestic solar water heater's internally piloted valve of the present utility model, its valve body [1] and mutual airtight connection of application valve body [10], it has a front end and has the guiding valve [8] that valve opening [8] and centre have spring [6] in valve body [1], have a plunger [2] in application valve body [10].Have certain space between the big end of plunger [2] and guiding valve [8], can charge into for example hydraulic oil or directly use air of liquid in it.Water inlet interface [7] connects water supply valve one side, and water outlet interface [5] connects solar water heater's storage tank one side, and overflow pipe interface [3] connects the overflow pipe of solar water heater.Make it to constitute an integral body with the storage tank and the tap water supply system of solar water heater.After the water in the storage tank is filled with, if do not close the tap water supply valve timely, then the water pressure in Ci Shi the storage tank continues to increase, promoting plunger [2] gradually moves, finally cause guiding valve [8] as moving right in the accompanying drawing 1, and valve opening [9] is closed, promptly closed whole water system.If pressure continues to increase, make plunger [2] itself be compressed, produce distortion, will open the overfall on the application valve body [10], make that the pressure in the system reduces, and be unlikely to damage whole solar water heater.If the pressure in the solar water heater storage water tank reduces, then guiding valve [8] is under the effect of the restoring force of spring [6], and move in the left side in accompanying drawing 1, thereby make valve opening [9] open, and continues water inlet and fill with water in the storage tank of solar water heater.If in the control of this valve, suitably increase other automatic control and warning device, can realize the alarm of the last water process of full automatic solar water heater and lack of water, full water and control automatically.
Claims (1)
1, a kind of domestic solar water heater's internally piloted valve, it has valve body [1], application valve body [10], valve body [1] and mutual airtight connection of application valve body [10], it is characterized in that in valve body [1], having a front end and have the guiding valve [8] that valve opening [8] and centre have spring [6], in application valve body [10], have a plunger [2].
