Description

Self-closed hydro valve when water cutting-off

The utility model belongs to the domestic use of water that uses in a kind of valve, particularly tap water pipe line and chews.

At present, along with the increase of high-rise, the existing problem that supplies water just seems particularly important in the city.Because the water source is relatively nervous, generally all adopts interruptions, feedwater time regularly, after people fetch boiling water and chew sometimes discovery anhydrous or when water, cut off the water suddenly, and forget and close Shui Zui.When coming water again,, will produce the generation of the incident of metalling run out, even cause flood if the next door is unmanned.For solving the problem of above-mentioned existence, now existing people has applied for patent to State Patent Office, wherein adopts more that the self-closing water of float-ball type chews.As, the application number of Patent Office of the People's Republic of China's bulletin on March 11st, 1987 is " a kind of float-ball type anti-overflow controller and the switch thereof " of CN85202023U etc.Problem of said structure ubiquity lacks practicability.Because the floating ball diameter less than water proportion should be slightly less than its cavity, so that ball float moves up and down, but in use, during the water proper flow, ball float should be on cavity top; After cutting off the water, ball float is owing to be subjected to the deadweight of suction clothes (drawing) power of cavity top institute resident water greater than this ball float, make ball float can't fall the cavity bottom sometimes, particularly when water stopping time more in short-term, do not have self-closing effect, although the diameter that dwindles the diameter of ball float or increase cavity can be avoided the problems referred to above, but the former can reduce by flow, the latter is than the benzene child, and is not attractive in appearance, can't promote.

The purpose of this utility model is to provide a kind of water-stopping self-closing water of new structure to chew, to solve the above-mentioned problem that exists.

The purpose of this utility model is achieved in that it includes valve body, valve plug, valve rod, ball float, ball float chamber, release link and Returnning spring etc., the one ball float chamber that has ball float, release link and a Returnning spring is arranged between valve body and water outlet, at the ball float top of chamber one outlet valve is arranged, between valve body and ball float chamber, a block water plate is arranged, be fixed with one by rotating the adjustment sheet of release link regulating water-quantity in the release link upper end.

Advantage of the present utility model is to increase by an outlet valve at the ball float top, makes self-closing function more reliable, has more practicability, have simultaneously simple to operate, advantage such as closed performance is good.

Below in conjunction with accompanying drawing specific embodiments of the present utility model is described further.

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

Referring to Fig. 1, concrete structure of the present utility model is between valve body 1 water outlet 10 a ball float chamber 12 to be arranged, on valve body 1, have one by the valve rod 2 of seal ring 4 with valve plug 3 sealings, be connected with a Returnning spring 6 that is fixed on the valve body 1 chamber wall on the valve rod 2 in valve body 1 chamber downwards, valve rod adopts pushes water-breaking structure.Can prevent the block water plate 5 that ball float 11 falls when between valve body 1 chamber and ball float chamber 12, a flowing water being arranged, one floating ball type discharge valve 13 is arranged at the top in ball float chamber 12, have one by the release link 9 of seal ring 4 in 12 bottoms, ball float chamber with screw plug 8 sealings, upwards be connected with a Returnning spring 6 that is fixed on 12 inwalls of ball float chamber on the release link 9 in ball float chamber 12, so that make release link 9 upwards promote ball float 11 back returns, also have one on the release link 9 in ball float chamber 12 by rotating the adjustment sheet 7 of release link 9 can regulate water flows.During use, as long as upwards press release link 9, then ball float 11 is shifted to the top in ball float chamber 12 under the effect of release link 9, at this moment the water in the pipeline has dashed block water plate by valve body 1 and has held ball float 11, water flows out by water outlet 10 thereupon, and rotary reset bar 9 can obtain needed current simultaneously.When the people when stopping (closing Shui Zui), as long as downwards by ovable valve stem 2, valve body 1 chamber and the pipeline close grave that enters the mouth, block water plate 5 returns, after ball float chamber 12 water flow out, ball float 11 drops to 12 bottoms, ball float chamber and blocks osculum in floating ball type discharge valve 13 exhausts, treat that Returnning spring 6 upsprings valve rod 2 behind the return, water is chewed and is closed.When cutting off the water suddenly, it is the same that water is chewed the principle of closing.If when coming water again, ball float 11 will tightly be blocked osculum and play self-closing effect under the effect of hydraulic pressure.

Claims (3)

1, a kind of water-stopping self-closing water is chewed, it includes valve body, valve plug, valve rod, ball float, ball float chamber, release link and Returnning spring etc., it is characterized in that between valve body and water outlet, having a ball float chamber that has ball float, release link and a Returnning spring, one outlet valve is arranged at the ball float top of chamber.

2, a kind of water-stopping self-closing water according to claim 1 is chewed, and it is characterized in that between valve body chamber and ball float chamber a block water plate being arranged.
