Abstract

The utility model relates to an intermittent supply water anti-leakage automatic cutting-off valve. A piston cylinder is arranged at a water inlet position arranged at the rear end of a valve body casing, and a piston is arranged in the cylinder. The front end of the piston is connected with an ejector rod which is arranged in a square hole support bracket. When water comes, pressure is generated to the piston by water, and the ejector rod and a water plug are pushed to move forwards. The water inlet of a water tap is clogged, and the phenomenon of water escaping can be prevented. The utility model has the advantages of simple structure and high sensitivity.

Description

Intermittent type water supply anti-leak automatic closing-water valve

The utility model belongs to the design and fabrication technology field of urban building with the automatic closing-water valve.

At present, the city all is to take to fix time water supply, owing to forget throttle down sometimes, causes a large amount of race of tap water to be emitted.Be used at present to prevent to run emit close water valve automatically, what have takes floating type, what have takes ratchet-type.But its using effect is all not really desirable.Also do not selling on the market and in life, using at present with the utility model like products.

The purpose of this utility model provides a kind of water valve that closes that has piston and push rod and water blocking.Can be at home nobody the time, come can close automatically behind the water.Solve the problem of metalling run out with this.

Structure of the present utility model has two square hole supports (7) in the bottom of valve shell (1) as shown in drawings, in the water inlet, rear end of valve shell one piston/cylinder (13) is arranged, and has water inlet (11) on the cylinder body, and a piston (2) is arranged in the cylinder body.Piston nose connects a push rod (4), and push rod places the hole of square hole support.The hole of square hole support is rectangular or ellipse, and push rod has certain up and down gap therebetween.Between piston and left side square hole support, a spring (3) is arranged.Spring housing is contained on the push rod.Have one cursory (5) on the push rod.Cursory between two stands.At the shell lower right part one reduction shift fork (9) is arranged, connect a water blocking (6) on shift fork, the rear portion of water blocking has one to inhale stifled magnetic sheet (8), inhales stifled magnetic sheet and is fixed on the shell.Have water tap (12) at the shell front end, there is an enclosed magnet (10) the water tap water inlet.Course of action of the present utility model is: after tap water drops down from inlet, the time piston produce pressure, when hydraulic pressure during greater than acting force of the spring, piston forward moves, and promotes push rod and moves forward, push rod withstands water blocking and moves forward until blocking the water tap water intake.The problem that prevents to metal run out takes place.Inhale stifled magnet owing to have on the water intake, magnet holds water blocking, so water blockoff is tight especially, is difficult for metalling run out.When the needs water, move the reduction shift fork with hand, shift fork is stirred water blocking, makes water blocking break away from the water intake of water tap, is inhaled stifled magnet plate then and sucks back original position, can guarantee water like this.Push rod no longer promotes water blocking during for the assurance water, and the interior ponding of housing this moment floats cursory, drives push rod and is higher than water blocking, makes its top less than water blocking, and the assurance water.When in the housing when anhydrous, push rod falls after rise to original position again.

The utility model is simple in structure, and is reasonable in design, highly sensitive, and it is convenient especially, reliable to use, and is the city Timing water supply, prevents to forget a kind of ideal device of metalling run out when closing water tap.

Be the universal component except that water tap, spring etc. in the utility model, all the other are non-standard component.Can adopt metal or plastics to make, cursory is lightweight material system, and water blocking can adopt inner lightweight material outsourcing iron sheet structure.Its enforcement relates to the processing specialty of metal and other materials, with reference to this specification and accompanying drawing, by each professional known technology processing assembling, can reproduce.

Claims

Intermittent type water supply anti-leak automatic closing-water valve, it is characterized in that two square hole supports (7) are arranged at the valve shell bottom, there is a piston/cylinder (13) water inlet, rear end of valve shell, have water inlet (11) on the cylinder body, one piston (2) is arranged in the cylinder body, piston nose connects a push rod (4), one spring (3) is arranged between piston and left side brackets, have one cursory (5) on the push rod, at the shell lower right part one reduction shift fork (9) is arranged, connect a water blocking (6) on the shift fork, the rear portion of water blocking has one to inhale stifled magnetic sheet (8), and there is an enclosed magnet (10) the water tap water inlet.
