Abstract

The utility model relates to a water cutoff valve for the replacement and the repairing of the tap. A valve body and a water tap are connected with a water supply pipe. The inner portion of the valve body is provided with a cylindric plug of the water cutoff valve. The top end of the cylindric plug of the water cutoff valve is provided with a flange convex edge and the end is a water cutoff end. The two sides are provided with hollow water inlets. The cylinder body of the valve plug is sheathed with a spring to be threaded into the valve body. In the common use, the valve plug downward moves under the water tap compression, the water cutoff end disassembles from the valve body and the water inlets are exposed in the water supply pipe, the water enters into the water tap by the inner cavity of the valve plug. When the water tap is disassembled, the spring resets to drive the valve plug to upward move, the water inlets are hid in the valve body. The water cutoff end closes the through hole of the valve body to obtain the automatic water cutoff purpose.

Description

Cutoff valve for replacing and repairing of tap

The utility model relates to tap, specifically a kind of be arranged on the water tap water intake before, pull down when water tap and to change the water cut-off device that can cut off current when repairing automatically.

In daily life, water is a very frequent action, as wash one's hands, take a shower, cook and prepare food etc.. none does not need water, thereby, water has become indispensable person in the life, and control the confluent size with water tap is to serve as light simple thing, almost in the existence that need all can see it with the place of tap water.Right under the high situation of frequency of utilization, repeatedly screw with loosen between water ring is caused wearing and tearing, accumulate over a long period and just can cause water tap leakage maybe can't screw down, the waste and the increase expense that form the water source are paid.

Because traditional water tap system directly is bolted on the water pipe, earlier this pipeline is not given sealing when desiring to change Xiu Shiruo, then change Xiu Shibi and cause a large amount of water sources to gush out, not only cause water waste, and may get wet and change the person of repairing, influence carrying out of work; Right general family or company there is no the sealing control valve unit, therefore often need by tap water water meter place sealing changing when repairing, and whole thus family or unit all can't waters, cause very big inconvenience, or water tower equipment person is arranged, and also need to put in order the spool road and give sealing, can make troubles equally; Although the pipeline top in water tap is equipped with sealing valve person, also needs earlier it to be closed.In view of this, change the work of repairing water tap and not only make and change the person of repairing and have to run around all the time wears him out outside the action of sealing, puzzlement that it brought and inconvenience are made us taking to heart in fact.

The purpose of this utility model provides a kind of water tap and changes and repair the sealing valve, this sealing valve is arranged between water pipe and the water tap, make in that change when repairing water tap can be with its automatic water stopping, avoid repairing the situation that causes other water tap " one disconnected hundred is disconnected " changing because of a water tap.

The utility model is a kind of in-flow sealing valve, it mainly is made of a valve body, a sealing valve plug and a spring, in the design, one of valve body end is the holding groove of internal diameter whorl and tool annular flange flange, and the other end to be the outer-diameter threads of inner edge tool penetration hole accept head, the enough sealing valve plug external diameters in footpath run through within this penetration hole.Such sealing valve body, can according to the feed-water end of its female end and water tap mutually pipe connect, according to the pipe joint of outer-diameter threads end and waterpipe mutually pipe connect.Sealing valve plug among the design is designed to a hollow cylindrical body, water outlet orifice ring tool one flange on its top, and the sealing end ring of its end is established a groove and in the both sides hollow out two water inlets are arranged.As follows the assembling of above-mentioned three main parts in addition: behind sealing valve plug cover upper spring, holding groove by valve body is inserted, and pass the penetration hole of accepting head, and in the annular groove of sealing valve plug water-stopping end, be nested with a glue ring washer at last again, promptly finish the assembling of this device.The sealing valve that so is assembled into, an end pipe is connected on the water supply pipe, and the other end and water tap pipe mutually connect.

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is described specifically.

Description of drawings:

Fig. 1 is an exploded perspective view of the present utility model.

Fig. 2 is a structure sectional view of the present utility model.

View when Fig. 3 is contained on the pipeline for the utility model.

See also Fig. 1.See by Fig. 1, present embodiment mainly is to be made of a valve body 30, a sealing valve plug 40 and a spring 51, wherein, one of valve body 30 end is the holding groove 31 of internal diameter whorl and tool annular flange flange, and the other end to be the outer-diameter threads of inner edge tool penetration hole 34 accept 32, the footpath is enough passed by sealing valve plug 40 external diameters within this penetration hole; Sealing valve plug 40 is a hollow cylindrical body, osculum 41 ring tools one flange 42 on its top, and water-stopping end 43 rings of end are established a groove 44 and are become two water inlets 45 in the both sides hollow out.

See that by Fig. 2 when sealing valve plug 40 cover upper springs 51 and after installing in valve body 30, spring 51 upwards tightly holds up valve plug 40 naturally, makes the glue ring washer 50 closely connected penetration holes with inclined-plane at valve body 30 that are arranged in the valve plug tail end.At this moment, because be positioned at the inside that two osculums 45 of water-stopping end packing ring 50 tops on the valve plug have risen to valve body 30, then in the pipeline 53 although water is arranged, also blocked by the packing ring of valve plug water-stopping end and can not enter and go in the cylindrical shell of valve plug 40, then valve body 30 tops just no longer include water, promptly are contained in the effect that this sealing valve on the pipeline just plays automatic water stopping.

See by Fig. 3, when filled with water tap on the valve body 30 52, water tap 52 compressing sealing valve plugs 40 move down, the flange of establishing until annular flange flange 33 that makes valve body 30 holding grooves 31 inner edges and sealing valve plug 40 tops ring 42 location that is fastened, and spring 51 is compressed between valve plug 40 and the valve body 30, at this moment water-stopping end 43 leaves penetration hole 34, and two water inlets 45 are revealed in outside the valve body 30 fully and communicate with pipeline 53, water in the pipeline 53 enters the cylindrical shell of valve plug 40 and through water tap water intake from two water inlets 45 of valve plug bottom, and the tap of at this moment fetching boiling water promptly has water supply.

Therefore, the utility model has the advantages that, after this water check valve is contained in the pipeline, when the filled with water tap, tap is opened the sealing valve plug, and when removing tap, spring is then strained the sealing valve plug, make its water-stopping end driving fit on the inclined-plane of the water flowing through hole of valve body, reach the purpose of automatic water stopping. In addition, the utility model only has four in addition part compositions, and structure is quite simple, and current are mobile in the valve plug cylindrical shell, both had enough flows, and spring does not contact with water supply again, has prolonged the life-span of spring, and water quality also can not be subjected to the pollution of spring. So the utility model has made things convenient for the repair of tap, has better practical value.
