Abstract

The utility model relates to an automatic water cut-off device for the tap change and repair. The utility model is mainly characterized in that the inner portion of a water cut-off valve body connected with a water tap and a water supply pipe is provided with a water cut-off valve handle fixed on a hollow cover body and sheathed with the hollow cover body and a strong spring. In the general use, the water tap compresses a cover body and a compression spring and pushes the water cut-off end on the valve handle away from the valve body, the water tap normally supplies the water. When the water tap is disassembled off, the spring resets to push the cover body to drive the valve handle to upward move. The water cut-off end on the valve handle closes the through hole on the valve body to obtain automatic watercut-off purpose. After using the utility model, the water tap can be changed and repaired at any time without the influence on the water supply of other taps.

Description

Automatic water cut-off device for tap change

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.

One of water system human survival important document, water tap indispensable especially equipment in the modern life is in the existence that need all can see it with the place of tap water.Utilizing the size of water tap control confluent is a convenient and simple thing, also just because of it be seen everywhere, everybody uses, so under the high situation of frequency of utilization, repeatedly screw and loosen between water ring is caused wearing and tearing, get off just to cause water tap leakage maybe can't screw for a long time, form the waste and the increase expense expenditure at water source.

Because traditional water tap system directly is bolted on the water pipe, need when repairing water tap earlier the pipeline sealing is changed the inconvenience when repairing and causes water waste in order to avoid cause when changing.All do not have the sealing control valve unit before the right at present general water tap, often need by tap water water meter place sealing, 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.This shows that traditional faucet device mode not only needs when repairing by can be for the sealing place to this pipeline sealing changing, make and change outside the person of repairing has to run around all the time wears him out, after water tap is removed fully, the sealing place also can waste by slime flux to the water between water tap, and 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 automatic water stopping device, this device bolt is located 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.

Above-mentioned purpose reaches like this: the solid automatic water stopping device that is made of a sealing valve body, a sealing valve rod, a brute spring and a copper sheathing of bolt on the feed-water end mouth of pipe of water tap.In the design, one of sealing valve body end is to be to be shaped on the internal thread holding groove, and the other end is that the outer-diameter threads of inner edge tool inclined-plane penetration hole is accepted head.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 rod among the design, one end are that valve plug water-stopping end, the other end are the bolt-lock end with screw thread; Copper sheathing is a hollow out lid, and has a keyhole that places for the bolt-lock end of sealing valve rod in circle centre position, simultaneously this copper sheathing both sides first half is vertically cut into two osculums.Above-mentioned four main parts are in addition done following assembling successively: the sealing valve rod is penetrated with the penetration hole of its bolt-lock end from the inner edge tool inclined-plane of sealing valve body, simultaneously on the sealing valve rod that this penetrates, be inserted in brute spring and copper sheathing, and the bolt-lock end that makes the sealing valve rod places in the keyhole of copper sheathing, with nut the sealing valve rod is locked on the copper sheathing then.The automatic water stopping device 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.

View when Fig. 2 is contained on the pipeline for the utility model.

Fig. 3 be contained on the pipeline for the utility model and remove water tap after view.

See also Fig. 1.See by Fig. 1, present embodiment mainly is to be made of a sealing valve body 10, a sealing valve rod 20, a copper sheathing 30 and a brute spring 40, wherein, one of sealing valve body 10 end system is the holding groove 11 of internal diameter whorl, and the other end to be the outer-diameter threads of inner edge tool inclined-plane penetration hole (not drawing among the figure) accept 13; Sealing valve rod 20 1 ends are valve plug water-stopping end 23, be designed in the present embodiment be constituted by inserting and putting a ring-shaped rubber packing ring 22 in the middle of the two rings shape copper sheet 21, and the other end are the bolt-lock end 24 of tool screw thread; Copper sheathing 30 is a hollow out lid, and in circle centre position tool one keyhole 31, the both sides first half with copper sheathing 30 vertically cuts into two osculums 32 simultaneously.After above-mentioned sealing valve rod 20 run through sealing valve body 10 by the inclined-plane penetration hole, put again brute spring 40 and with nut 41 with bolt-lock end 24 bolt-locks of sealing valve rod 20 on the keyhole 31 of copper sheathing 30, then finish the entire combination of this device.

Working state of the present utility model is by Fig. 2, shown in Figure 3.See when the time by Fig. 2 at device, pressure compression copper sheathing 30 when water tap 42 is locked in holding groove 11, and compression brute spring 40 and the water-stopping end 23 that drives sealing valve rod 20 leave penetration hole 12, and current are full of in the device via the osculum 32 of penetration hole 12 and copper sheathing 30; When water tap 42 was opened, the water in the device just can flow out for using.See by Fig. 3, when water tap 42 because of leaking or fault is changed when repairing, in unscrewing the process of water tap, the elastic force of nationality brute spring 40 up pushes up copper sheathing 30 and drives sealing valve rod 20 upwards, when water tap 42 takes off fully, the water-stopping end 23 of sealing valve rod 20 is just combined closely on inclined-plane penetration hole 12 and with the water route total blockage of pipeline, is reached the purpose of automatic water stopping.

Therefore, the utility model has the advantages that, after this device is contained in the pipeline, when the filled with water tap, tap is opened the sealing valve rod, and when removing tap, brute spring is then strained the sealing valve rod, make its valve plug water-stopping end driving fit on the inclined-plane of the water flowing through hole of sealing valve body, reach the purpose of automatic water stopping. The utility model is simple in structure, and automatic water stopping is effective, has made things convenient for the repair of tap, has better practical value.
