Description

A kind of anti-leakage tap

Technical field

This utility model relates to a kind of faucet, even if particularly relating to a kind of faucet that can open after cutting off the water to forget to close during water water without the anti-leakage tap flowed out again。

Background technology

At present, realize known ordinary faucet can not forget to close faucet when cutting off the water being automatically switched off, cause water when cannot prevent again water to overflow pond and cause secondary harm；Some faucet are only capable of being closed by timing after pressing water tap realizing water saving at present, but this kind of faucet does not consider everyone water consumption, generally, user needs to press switch repeatedly just can make the water yield meet demand, thus cause user in-convenience in use, namely man-machine efficacy is low；Although inductive water tap is absent from such problem, but cost is higher, it is impossible to be widely popularized, and there is the potential safety hazards such as electric leakage。Though having minority faucet can realize leakage proof function in theory at present, it adopts ball float principle mostly, and operation controllability is poor, and reliability is low。

Utility model content

The purpose of this utility model, is to provide a kind of anti-leakage tap, and this faucet can ensure that when forgetting to close after faucet water when cutting off the water, water flows out without from faucet again, thus not havinging the accident of metalling run out。

The technical scheme is that

A kind of anti-leakage tap, being mainly by including valve body, spool, knob, upper end cover and bottom end cover is that main element is assembled into。

A kind of anti-leakage tap, including tap main body and anti-mechanism of metalling run out；Tap main body includes valve body, spool, rotary switch, upper end cover and bottom, and bottom has water inlet；Upper end cover and bottom are connected with the screw thread upper port inwall with valve body and lower port inwall respectively, valve body offers outlet, tapped centre bore is stamped in upper end, external screw thread is arranged at spool top, spool upper end is connected with the centre bore hole wall of upper end cover by screw thread, and the bottom of spool is positioned at valve body, and rotary switch is fixed on the upper end of spool, tap main body is known technology, it is characterised in that:

Described anti-mechanism of metalling run out, including piston component and pull-fork assembly, piston component includes piston and the first spring, piston has inlet opening sealing cap, spool lower end offers piston chamber, first spring and piston load in piston chamber, and one end of the first spring is supported on spool, and the other end of the first spring is supported on piston。

Described pull-fork assembly includes three shift forks, the second spring and spring catch；Three shift forks are along the circumferential direction equidistant to be fixed on spool lower end outer wall, and is an overall structure with spool。Offering spring housing on valve interior wall, the second spring is installed in spring housing, and one end of spring catch is inserted in spring housing, and the other end of spring catch is supported on spool, and angularly disposed on spring catch have push rod。

Operation principle of the present utility model:

In FIG, shift fork and spool are integrated, and when rotation turn switch, spool, along with switch rotary, drives shift fork to rotate together。When there being water, rotation turn switch, open faucet, along with rotary switch rotates, shift fork rotates, when touching the push rod of the second spring catch, shift fork is by exerting a force to the second spring catch, make spring-compressed, second spring catch enters in shock mount room therewith, blocking device is unblanked, piston overcomes the thrust of gravity and the first spring to move from bottom to top under the effect of hydraulic pressure, water is made to flow out, piston encounters spool, continue rotary switch, strengthen water yield, rotation due to rotary switch, shift fork leaves spring catch, under the second spring thrust effect, spring catch ejects, touch the outer wall of piston, now, blocking device is in unlocking condition。

In figure 3, when faucet needs to close, opposite direction rotation turn switch, piston moves downward under the promotion of spool, has blocked water inlet, stops supplying water, and the outer wall of spring catch contact piston, now spring catch is inoperative。

In the diagram, state of cutting off the water, open faucet, rotation turn switch, shift fork rotates along with rotary switch, promotes the second spring catch, and blocking device is unblanked, owing to there is no hydraulic piston invariant position under the effect of the first spring and gravity, but when shift fork does not reach the second spring catch, spring catch ejects under the elastic force effect of the second spring, be bound to below spool with in the gap of piston, seized piston, so as to can not move up。When water, even if there being the effect of hydraulic pressure, owing to spring catch is in two component spaces and acts on piston face, to the constraint of one vertical direction of piston, prevent the upper shifting of piston, make water cannot enter from water inlet, prevent the outflow of water, thus having reached anti-metalling run out。

The utility model has the advantage of: when user opens faucet, anhydrous and when forgetting to close faucet, the water inlet of this utility model energy self-closed faucet, it is prevented that metal run out, and novel structure, easy to use。
