Abstract
The utility model discloses a water leakage safety valve of a solar water heater, belonging to fittings of the solar water heater; the bottom in the center inside a valve body connected with a water tank is provided with a cambered surface flexible silicon sheet by a connecting piece, a limber hole is arranged at the bottom of the valve body around the connecting piece and is also arranged just below the cambered surface flexible silicon sheet; a connecting base connected with a vacuum tube is arranged under the bottom of the valve body. Compared with the prior art, the water leakage safety valve of the solar water heater of the utility model has the characteristics of reasonable design, simple structure, easy processing and convenient use, etc., and can effectively prevent water in the water tank from leaking after the vacuum tube fractures.
Description
Technical field
The utility model relates to a kind of solar water heater accessory, specifically the solar water heater safety valve that leaks.
Background technique
Generally all have water to pass through in the vacuum tube of solar water heater, vacuum tube is in case damaged, and tap water can flow out always, and the current light in water tank brings very big inconvenience to the user.At present, at the vacuum tube opening, because without any leakage-proof apparatus, solar water heater in use, in case the situation that vacuum tube breaks takes place, not only influence the normal thermal-arrest of vacuum tube, and can cause a large amount of tap water wastes, influenced people's living environment when bringing very big inconvenience to the user.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, and a kind of solar water heater that can effectively prevent vacuum tube to break water in the rear water box reveals safety valve that leaks is provided.
The technological scheme that its technical problem that solves the utility model adopts is: be provided with cambered surface flexible silicon film with centre bottom in the valve body that water tank is connected by link, valve body bottom around the link is provided with the water port, the water port is under cambered surface flexible silicon film, and the below of valve body bottom is provided with the connecting base that links to each other with vacuum tube.
The opening of described cambered surface flexible silicon film has upwards been lifted up.
Under the normal condition, because identical with the hydraulic pressure in the water tank in the vacuum tube, institute is so that the shape invariance of cambered surface flexible silicon film, and water passes through the relative circulation of realization water in the water port below the cambered surface flexible silicon film; After vacuum tube broke, the hydraulic pressure in the water tank was greater than the pressure in the vacuum tube, and under the effect of hydraulic pressure, cambered surface flexible silicon film warpage blocks the water port below it, prevents that water from flowing in the vacuum tube that breaks.
The solar water heater of the present utility model safety valve that leaks is compared with prior art, the solar water heater of the present utility model safety valve that leaks is compared with prior art, have reasonable in design, simple in structure, be easy to processing, characteristics such as easy to use, can prevent effectively that the water that vacuum tube breaks in the rear water box from revealing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the leak structural representation of safety valve of solar water heater.
Among the figure: 1, water tank, 2, valve body, 3, cambered surface flexible silicon film, 4, the water port, 5, vacuum tube, 6, connecting base, 7, link.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
The solar water heater of the present utility model safety valve that leaks, centre bottom in the valve body 2 that is connected with water tank 1 is provided with cambered surface flexible silicon film 3 by link 7, the opening of cambered surface flexible silicon film 3 has upwards been lifted up, valve body 2 bottoms around the link 7 are provided with water port 4, water port 4 is under cambered surface flexible silicon film 3, and the below of valve body 2 bottoms is provided with the connecting base 6 that links to each other with vacuum tube 5.
Solar water heater of the present utility model its processing and fabricating of safety valve that leaks is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (2)
