The utility model is characterized in that the inside of the valve cavity is provided with a valve seat, the valve seat is provided with a float valve at the position communicated with the water inlet, and a closing seat is provided with an opening mechanism which can enable the float valve to open at the position corresponding to the float valve. After the water supply is cut off, a running water tap is not closed, and the running water tap can be automatically closed to stop the water when the water is supplied again. The utility model has the advantages of simple structure, compact structure, low cost, and convenient assembly and disassembly; moreover, the utility model is free from the limit of a pipeline and the position of the running water tap at the time of installation.

Description

The automatic stop valve of cutting off the water

The utility model relates to and a kind ofly cut off the water the back and water tap does not cut out, can close voluntarily, the automatic stop valve of cutting off the water that water is stopped after supplying water again.

Existing commercially available water tap is the flowing of water in the controlling plumbing fixtures, and two functions of open and close are arranged, and provides convenience for people use tap water.But as do not note opening it when cutting off the water, in the back of supplying water again owing to can not close voluntarily, cause the waste of water resources even cause floods.

In view of above reason, the purpose of this utility model is the automatic stop valve of cutting off the water that can close automatically after supplying water again in order to provide a kind of back water tap of cutting off the water not close.

The valve body that contains water intake, water outlet and valve pocket is arranged in the utility model, it is characterized in that valve seat is arranged in the valve pocket, on the valve seat with position that water intake communicates on float valve is arranged, on the valve seat with the float valve relevant position on the opening mechanism (referring to Fig. 1) that float valve is opened is arranged, utilize ball float and valve seat directly to act on sealing liquid.

Have an end to stretch on the valve seat and the all-or-nothing piece that float valve can be opened in the above-mentioned opening mechanism, be contained in the sealing (10) between valve seat and valve body, the other end of all-or-nothing piece can contact (referring to Fig. 1) with sealing (10).

Being positioned at all-or-nothing piece on the above-mentioned all-or-nothing piece stretches out between end of valve seat and valve seat end face return reed (referring to Fig. 1) is arranged.

Above-mentioned valve body and valve base chamber are positioned at the float valve place sealing (7) (referring to Fig. 1).

Above-mentioned float valve is feather valve (referring to Fig. 1), can be hollow core valve and also can be the multilayer elastic valve.

Ball float becomes ball valve with valve seat combination, referring to Fig. 1, is connected to the utility model in the pipeline correct position or between pipeline and water tap.As can be seen from Figure 1, after cutting off the water, come water again and from Fig. 1 the mouth of pipe shown in arrow when water inlet, water seal in the future is firmly reliably under self gravitation and hydraulic pressure for float valve; During unlatching, stir the all-or-nothing piece in the opening mechanism, all-or-nothing piece backs down float valve, just tap water downstream the passage direction of arrow flow out, enter water tap, this moment float valve at buoyancy of water as power float downward up (position shown in double dot dash line among Fig. 1).Unclamp all-or-nothing piece, all-or-nothing piece moves to sealing part downwards and stops under the effect and hydraulic action of return reed, and whether the water tap no matter water intake connects was opened or closed if water does not stop this moment, and float valve all is in the enable possition, top; Do not open, cut off the water or water tap is closed when cutting off the water when water tap, float valve is fallen automatically and is sealed valve seat, if when water comes again, then automatic cut-off water outlet.

Compare with existing water tap, the utlity model has following advantage:

1, the utility model adopts the directly sealing principle of coming water of gravitational force ball-valve, and opens ball valve and adopt mechanical all-or-nothing piece near ball valve below operating principle, and is simple in structure, compact, cost is low;

2, assembly easy accessibility, manufacturing is simple;

3, selection is extensive, can adopt steel part, copper spare, working of plastics, rubber parts, rubber and plastic spare, stainless steel part etc.;

4, the utility model has been realized the separate installation of water tap with pipeline location, not limited by the mounting point;

5, beautiful shape, generous, modern design;

6, purposes is wide, not only can be used on the water supply pipe, also can be used for other as aspects such as chemical industry, machineries.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation.

Referring to Fig. 1, water intake 2, water outlet 3 are arranged on valve body 1, open mouth 4.The valve seat 5 that plastics are made places the valve pocket 6 of valve body.Between valve seat and valve body, rubber seal 7 is housed being positioned at the water inlet.Spherical crown ball control hole 8 is arranged on rubber seal 7 and the valve seat 5, and elasticity float valve 9 parts can fall into control hole 8 and cooperate with it.Rubber seal 10 is equipped with at unlatching mouth 4 places on valve body, and nut 11 is loaded on unlatching mouthful place and rubber seal 10 is compressed.All-or-nothing piece 13 1 ends in the opening mechanism 12 can contact with rubber seal 10 and the other end stretches in the valve seat and slidably back down float valve 9.Return reed 14 is contained on the all-or-nothing piece and is positioned at all-or-nothing piece and valve base chamber.

Claims (5)

1, the automatic stop valve of cutting off the water, the valve body that contains water intake, water outlet and valve pocket is arranged, it is characterized in that in the described valve pocket valve seat being arranged, on the valve seat with position that water intake communicates on float valve is arranged, on the valve seat with the float valve relevant position on the opening mechanism that float valve is opened is arranged.
