Abstract

The utility model belongs to a valve, and more specifically, the utility model relates to a float ball self-cutting off water tap which is suitable for the valves for water supply in civil buildings. The float ball self-cutting off water tap is composed of a valve body, a float ball, a valve cover, a handle, a valve rod, etc., wherein, the float ball is placed in the valve body in a fall way; a small pore channel arranged at the upper part of the valve is communicated with the lower cavity of the valve body, the valve cover and the upper part of the valve body is matched by screw threads, and the valve rod is arranged in the valve body; a sealing rubber plate is affixed on a valve plate and is fixed at the lower end of the valve rod, a screw cap facilitates the valve rod to be fixed on the valve body by the preparing cap, and the handle is arranged at the upper end of the valve rod. The utility model has the advantages of stable and reliable working principle, simple structure, and convenient maintenance; besides, the utility model is in accordance with the original use habit, and the utility model can effectively prevent the accident of water running.

Description

Float ball self-cutting off water tap

The utility model belongs to valve, and a kind of more precisely Float ball self-cutting off water tap is applicable to the water supply valve of civil building.

Forget that at present closing water valve causes the accident of metalling run out when coming water again and bringing disaster to the neighbourhood to happen occasionally, become a great problem of living in front yard, house, puzzlement building, these people have also been made various effort, seek the way of water-stopping self-closing owing to cutting off the water.

Given this, the purpose of this utility model is to provide a kind of Float ball self-cutting off water tap of realization water-stopping self-closing that can be effective.

The purpose of this utility model realizes by following technical measures: Float ball self-cutting off water tap is made up of parts such as valve body, ball float, valve gap, handle, valve rods, wherein ball float falls to putting in valve body, valve body top has little duct to be communicated with the valve body cavity of resorption, valve gap and valve body top screw-thread fit, valve stem equipment is in valve body, the sealing offset plate is attached at and is fixed on the valve rod lower end on the valve plate, and nut is fixed on valve rod on the valve body by being equipped with cap, and handle device is in the valve rod upper end.

In conjunction with the accompanying drawings concrete structure of the present utility model is further described in detail.

Fig. 1 is a structural drawing of the present utility model.

Fig. 2 is a B-B sectional view of the present utility model.

Fig. 3 is user mode figure of the present utility model.

Fig. 1 is embodiment of the present utility model.

With reference to Fig. 1, Float ball self-cutting off water tap is made up of parts such as valve body 1, ball float 3, valve gap 2, handle 4, valve rods 5, wherein ball float 3 falls to putting in valve body 1, valve body 1 top has aperture road 10 to be communicated with valve body 1 cavity of resorption, valve gap 2 and valve body 1 top screw-thread fit, valve rod 5 devices are in valve body 1, and sealing offset plate 9 is attached at the lower end that is fixed on valve rod 5 on the valve plate 8, nut 7 is fixed on valve rod 5 on the valve body 1 by being equipped with cap 6, and handle 4 devices are in valve rod 5 upper ends.

Under the user mode, under the normal condition, as Fig. 3, each chamber all is full of water in the valve body, and the open and close valve body can not change the state of ball float, and at this moment it and ordinary faucet are as good as.

Open handle after cutting off the water, or cut off the water suddenly when supplying water, the water in the pipeline all will flow only, only among the valve body cavity of resorption g water is arranged, ball float is by flumping the position that the people closes down certainly, as Fig. 1, when coming water again, current enter the c chamber from population a through runner b, because the hydraulic pressure in the c chamber is higher than the hydraulic pressure in g chamber, promptly the pressure above the ball float is greater than following pressure, its pressure reduction is greater than the buoyancy of ball float, so ball float can not float, valve body top is communicated with by aperture 10 with cavity of resorption g, first exhaust this moment, back draining, flow out through water valve h and water nozzle i, fine current can be as the signal that water is arranged, and unlikelyly causes a large amount of metalling run out, during water, close handle earlier, make c, hydraulic pressure equates in the g chamber, ball float is subjected to buoyancy of water to rise to the position of d, return to normal operating condition, open handle again, then current pass through valve body smoothly.

The utility model working principle is reliable and stable, and is simple in structure, easy to maintenance, meets original use habit, can effectively prevent the accident of metalling run out.

Claims

1, a kind of Float ball self-cutting off water tap, form by parts such as valve body, ball float, valve gap, handle, valve rods, it is characterized in that: ball float falls to putting in valve body, valve body top has little duct to be communicated with the valve body cavity of resorption, valve gap and valve body top screw-thread fit, valve stem equipment are in valve body, and the sealing offset plate is attached at and is fixed on the valve rod lower end on the valve plate, nut is fixed on valve rod on the valve body by being equipped with cap, and handle device is in the valve rod upper end.
