Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

As Fig. 1, shown in Fig. 2, the switching valve of a kind of water tap of the present utility model, comprise valve body 1 and valve rod 2, described valve body 1 is hollow cylinder, above in valve body 1, periphery is provided with a plurality of water inlet A, the two ends up and down of valve body are upper water-out mouth B and lower outlet C, described valve rod 2 is nested into valve body 1 inside, in the lower end of valve rod 2, be provided with positioning step 22, the upper end of valve rod 2 is provided with tapered step 21, first by rubber cup 3 through after tapered step 21, be sleeved on positioning step 22 above, and Returnning spring 4 is sleeved on to the periphery of rubber cup 3, then valve rod 2 integral body are packed into from lower outlet C, making rubber cup 3 and Returnning spring 4 all face position with the lower outlet C interior lower end of valve body 1 installs.Finally tapered rubber pad 5 is packed into from upper water-out mouth B, and pass the tapered step 21 of valve rod 2, make tapered rubber pad 5 be sleeved on the upper end of valve rod 2, and the periphery of tapered rubber pad 5 and the upper water-out mouth B internal face of valve body 1 are sealed and matched.Thereby realize all energy movable sealings of the upper-end surface of valve rod 2 and the upper water-out mouth B of lower end surface correspondence and valve body 1 and lower outlet C, and above in valve body 1, be provided with limited step 12, at valve body 1 outer wall between water inlet A and limited step 12, be provided with retaining thread 11, the upper outer wall surface cover that is arranged in valve body 1 is equipped with two seal rings, wherein seal ring 6 devices are at upper-end surface periphery, seal ring 7 is sleeved between retaining thread 11 and limited step 12, thereby the modular type of realizing whole switching valve is installed, easy and simple to handle, sealing effect is splendid.

Working principle: thus valve rod 2 switches two water outlet B and C with the promotion of hydraulic pressure, when upper water-out mouth, B closes, when lower outlet C opens, the water pressure pushing valve rod 2 of water inlet A, make valve rod 2 overcome the elastic force of Returnning spring 4, there is certain space with the lower outlet C interior lower end face of valve body 1 in rubber cup 3, fluid flows out from lower outlet C, rubber cup 3 opens because of suction, in conjunction with tapered rubber pad 5, effectively control upper water-out mouth B water adverse current, when upper water-out mouth B opens, when lower outlet C closes, water inlet A water pressure pushing valve rod 2, tapered rubber pad 5 on valve rod 2 is closely cooperated with the upper water-out mouth B internal face sealing of valve body 1, effectively control lower outlet C water adverse current, fluid flows out from upper water-out mouth B, avoid the generation of bite phenomenon, effectively reach sealing effect, the reinforcement of leakproofness is very obvious, thereby more effectively controlled water adverse current.

In the lower end surface of valve body 1, be provided with in addition a plurality of V-type mounting grooves 14, below in valve body 1, outer wall is provided with two through holes 13, V-type mounting groove 14 can auxiliary valve body 1 integral installation in the required pipe-line equipment of correspondence or on faucet subject, valve rod 2 can be selected copper bar or plastic bar or stainless steel, according to different customer demand corresponding specification, configure, and do not affect the performance of whole switch valve structure.

Above-described, be only a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
