Abstract

The invention discloses a controllable water valve, and relates to a water supply switch. When water is needed, water supply is started by pressing a water valve button once, and the water valve can be closed by pressing the water valve button once again when water quantity is reached. The controllable water valve comprises a valve body, a valve cover, a valve spool and a return spring. The controllable water valve is characterized in that a plurality of grooves are uniformly formed in the inner wall of the upper portion of the valve body, one deep groove and one shallow groove which are adjacent are alternately arranged, the number of the grooves is even, a projection between each two adjacent grooves and the section of the lower end of each shallow groove are made into the same inclined surface, and a button column, a positioning column and a water supply valve spool are arranged in the valve. The controllable water valve can be widely applied to pipeline systems for supplying a preset quantity of liquid.

Description

But a kind of water control valve

Technical field

The present invention relates to a kind of Water supply switch valve.

Background technique

Existing water supply valve such as foot valve tramp with one's feet when supplying water and step on the foot-operated arm of water valve, and water valve is opened water supply, closes when pin unclamps water valve, stops to supply water; When the needs water yield is many slightly, pin must be trampled foot-operated arm for a long time, can realize continuing to supply water.So just influence working efficiency.

Summary of the invention

The present invention is directed to above-mentioned technology existing problems, but a kind of water control valve is provided, in the time of realizing needing water, press the water valve button No. one time, namely water supply start when reaching the water yield, is pressed a water valve button again and can be closed.

The technological scheme that the present invention addresses the above problem employing is: but a kind of water control valve is provided, comprise valve body, valve gap, spool, Returnning spring, it is characterized in that: the valve body upper inside wall is provided with even a plurality of groove, adjacent notches one dark one shallow alternate row's example, and groove quantity is even numbers; Between adjacent notches the projection with shallow grooves under end section make same inclined-plane; Be provided with button post, locating column, water supply spool in the valve; Stretch out from valve body top top cover opening on the top of button post, radially there is projection the bottom along wall, projection quantity is corresponding with valve interior wall groove number, height of projection and the shallow grooves degree of depth are complementary, lower shaft is arranged to flexuose to the lower edge, sawtooth quantity is identical with protruding number, and groove is corresponding between row's example of sawtooth and projection, staggers with projection; Button post bottom is interior cylindrical cavity; Cylindrical body is made on locating column top, its diameter is can stretch into button post lower cavity, and can relatively rotate and be advisable, locating column lower end outer wall is provided with projection, height of projection is advisable can stretch on the valve body dark groove, the snag axis end section Bevel that makes progress, and its bevel direction and valve inner groove are complementary with protruding lower edge bevel direction, locating column projection quantity is consistent with the dark groove number of valve body, and locating column is established cylindrical cavity in the lower end; Radially have a circular hole on the water supply spool, pass through for flowing water, the bottom makes an interior cylindrical cavity internal diameter and the spring size is complementary, the upper end is made cylindrical, the diameter of cylinder and locating column lower end inner cavity are complementary, and water supply spool sidewall is provided with at least one projection, and corresponding valve body position also is provided with groove with it, its effect is that the spool that prevents from supplying water rotates with locating column, and influence is supplied water; One end of spring is connected the locating column lower end, and the other end is supported on the valve body bottom, and the elasticity distance of spring is to guarantee that compression stroke closes, opens the stroke of required movement greater than the water supply spool.The projection length of locating column is a bit larger tham water supply spool opening diameter and is added the edge, hole far from valve body waterpipe jointing radial distance.

If valve body is in the water supply state during use, press the button post, the button post moves down along valve body, promotes locating column and moves down, and locating column skids off the groove on valve body top, and under the sawtooth effect of button post lower end the rotation one tooth pitch, the release button post, projection is up along raised item and the inclined-plane, groove lower end on valve body top on the locating column, and rotates to the shallow grooves sloped roof place of valve body and stop, the spool that supplies water this moment is displaced downwardly to water supply hole and water pipe dislocation, and water supply is closed; When pressing the button post again, locating column rotates a tooth pitch again under the sawtooth effect of button post lower end, this moment the raised item on the locating column again with valve body on dark groove match, the release button post, locating column and water supply spool move up under the lower springs effect, to locating column lower edge contact valve interior wall projection, the water supply hole of water supply spool communicates with the water supply tube chamber, and this moment, valve body was opened water supply.

But the pipe-line system of the present invention's extensive use prearranging quatity supply liquid, it is light to be that liquid quantitative becomes.

The invention will be further described below in conjunction with drawings and Examples
