Abstract
The utility model relates to a diaphragm cut-off apparatus for a solar hot-water bag, which is composed of a diaphragm-coat body. The film-coat body is a hollow wedge body which is tabular. The orifice of the interface end (water inlet) is unequal to that of the control end (water outlet). The utility model has the advantages of simple structure, low cost, easy installation, easy use, large water-supply flow quantity and favorable automatic control effect, and is suitable for matching with various flexible hoses with small diameters.
Description
The utility model belongs to the control valve in the water supply line, is the automatic controlling diaphragm switch that a kind of solar hot-water bag is used specifically.
The control valve that uses in the prior art has two kinds: a kind ofly be metal valve, another kind is a plastic valve, mostly is made of valve body, spool.The former is the non-ferrous metal valve, so though the high latter of price is low than the former cost, in use because sealing is bad, cause leakage easily.The all water supply flows that exists of above-mentioned two kinds of valves are slow, when closing, need personnel selection to control.
The purpose of this utility model provides the membrane switch that a kind of solar hot-water bag is used, and can control automatically when making water pipe break away from water tap and close, and can prevent the refluence of water effectively.
For achieving the above object, solution of the present utility model is: Membrane cover (2) is one to be the wedge-like body of flat shape; And interface end (water intake) (1) is unequal with the aperture of control end (water outlet) (3).
When inserting membrane switch, the interface end (1) of big trepanning is connect on the water supply stopcock, the control end of elongated trepanning (3) places in the water pipe, when close water supply stopcock water pipe is broken away from after control end (3) lose hydraulic pressure and auto-closing has stoped the refluence of water.
The utility model has compared to existing technology: simple in structure, and low cost of manufacture, water supply flow is big, and is easy to use, controls effective automatically.
The drawing explanation of accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the another kind of embodiment of Fig. 1.
The utility model embodiment in conjunction with the accompanying drawings is described in detail:
See the embodiment of accompanying drawing 1.Adopt plastic membrane of polyvinyl chloride to be converted into bilayer, by the high-frequency thermocompressor hot synthetic type, make Membrane cover body (2) be the wedge-like body of flat and the trepanning of interface end (water intake) (1) should be used for connecting water supply stopcock greater than the trepanning of control end (water outlet) (3) for hollow; Control end (water outlet) (3) is placed in the water pipe, and for easy to install and use, the both sides of Membrane cover body (2) all have gradient.
See the another kind of embodiment of accompanying drawing 2.Two gradients of Membrane cover body (2) excessively place have fillet, and are survivable when being connected with water supply stopcock in order to alleviate.
When using membrane switch, earlier the interface end (water intake) (1) of membrane switch body (2) is inserted on the water supply stopcock, be connected on the water tap after with hose membrane switch body (2) cover being gone into then.When supplying water, press water is opened normal water supply with control end (water outlet) (3); When stopping to supply water, after water supply stopcock closed, the water pipe of mantle switch terminals can be broken away from water tap, because of the control end (water outlet) (3) of elongated trepanning recovers flat form again after losing hydraulic pressure, and auto-closing has been controlled the refluence of water effectively.
Claims (2)
1, a kind of solar hot-water bag membrane switch is to be made of the Membrane cover body, it is characterized in that: Membrane cover (2) is a hollow wedge-like body that is flat; And interface end (water intake) (1) is unequal with the aperture of control end (water outlet) (3).
2,, it is characterized in that Membrane cover (2,12) two hypotenuses can have fillet in excessive places directly excessive or two hypotenuses by the described solar hot-water bag membrane switch of claim 1.
