Processing for convenience can be at valve body liner one valve pocket, and valve pocket and valve body connect firmly, at least open a hole on the sidewall of valve pocket, valve outlet is aimed in the hole, can leave a circular gap between valve pocket and the valve body, with when the described hole misalignment valve outlet, do not influence water outlet yet.System one boss is stuck on the boss of valve sleeving inner wall closing power assistant spring on the inwall of valve pocket lower end, and valve disc origin water direction is against on the end face of valve pocket, is provided with seal ring in case leak from here between valve pocket and valve body.

In order to improve the stability of valve rod, close power assistant spring and can adopt the tower spring.

The stop valve that the utility model provides reaches the purpose of closing sealing by valve disc coming water to contact on equidirectional on the valve body, make sealing more reliable, in addition, with dynamic and static ratchet and Returnning spring, close power assistant spring and replace flimsy screw rod, nut structure, the life-span of stop valve is prolonged, and increase press-started and function scram is arranged, easy to use.

Below in conjunction with embodiment the utility model is described in further detail.
