Description

A kind of automatic shutoff valve

Technical field

The utility model relates to a kind of running water valve, specifically is a kind of automatic shutoff valve.

Background technique

Existing running water valve all is to be critical piece with the spool, the opening and closing of valve need the human hand to move handle to realize, this valve is cut off the water temporarily and is forgotten under the situation of turning off the tap running into, nobody can cause water to flow out in vain for a long time because of the scene after coming water, produce unnecessary water resource waste, even also might go out to influence the life of other resident family because of the water spill-over.In order to solve above-mentioned these problems that existing running water valve exists, existing at present people has designed the valve of energy automatic shutoff, though these valves can address these problems, but most complex structure, valve volume is big, manufacture cost is high, though also some is simple in structure, and poor reliability.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, easy to operate and safe and reliable automatic shutoff valve.

The purpose of this utility model reaches by following technical measures: the valve body of this automatic shutoff valve is " ⊥ " type threeway shape, its intake pipe and outlet conduit are straight-through, with advance, in vertical another pipeline of outlet conduit and in the center region of valve body sealing seat is installed, seal ring, spring, valve rod, spool, valve ball and switch hook, switch hook is hinged on by the water intake of outlet conduit, it comprises transverse slat and the gib head angled with transverse slat, this gib head can be dialled the valve ball of shutoff on the outlet conduit water intake from water intake when bearing pin rotates in switch hook, between transverse slat and the valve bottom spring is installed; Spool is a cylindrical shell, and it laterally is placed on the transverse slat of switch hook, and axis side's line of its center hole is consistent with the axial direction of water-in and water-out pipeline, but the valve ball floating ground is loaded in the spool; The port that sealing seat is installed in the pipeline is located slightly down, and the lower end of bellows closely is fixed on the port of sealing seat place pipeline, and the end face of switch cover is stretched out in its termination, upper end; The lower end of valve rod is fixed on the spool, after passing sealing seat, the upper end is fixed in the termination, upper end of bellows, between the hole of it and the sealing seat that passed seal ring is installed, on the valve rod between sealing seat and the spool spring is installed, switch cover is stuck in the annular groove under the bellows termination; Also be processed with a hole on the wall thickness of outlet conduit, the aperture is connected to water pipe, and the wall thickness that the other end of water pipe passes the facade of switch cover and pipeline is inserted in the water-inlet cavity that sealing seat and bellows constitute, switch cover the upright and water inlet place of passing is provided with vertical bar hole.

The above-mentioned spring that is installed on the valve rod is the turriform spring of upper end diameter greater than lower end diameter.

The water inlet of above-mentioned outlet conduit also is equipped with seal ring.

The utility model is work like this: when cutting off the water, because the effect of spring, spool and valve ball are in the bottom of valve body center region, when coming water, if water tap is closed, the water that then enters bellows rises the termination of bellows, and this moment, valve rod was mentioned spool and valve ball.When coming water, if water tap is in opening state, then shutoff is in the water inlet of outlet conduit automatically under the effect of hydraulic pressure for valve ball, and this moment, water automatically shut down.After resident family goes home, at first water tap is closed, press the bellows termination then downwards, at this moment the gib head of switch hook is dialled the water intake that leaves outlet conduit with valve ball, and valve body is in the water flowing state.

The utility model is being cut off the water temporarily and is being forgotten under the situation of turning off the tap and can cut off the water supply automatically when coming water, thereby avoids unnecessary water resource waste, compares with existing automatic shutoff valve, the utility model is simple in structure, the small and exquisite uniqueness of external form, and easy to operate, safe and reliable.

Below in conjunction with drawings and Examples the utility model is described in further detail.
