Abstract

The pressure-controlled leakage-free valve consists of valve body equipped with valve core covered with flanged sealing cover for isolating from fluid and driving piece and capping type turn-handle which can be used to cover and operated the driving pieces of spring, etc., protect them from external interference and directly matched with the valve body. It is characterized by that the sealing cover and valve core can be loose-tightly fitted, the valve core is divided into two portions of head and tail, said tail portion is elastically connected with turn-handle. When it is under no pressure, the upward turning of the turn-handle has no influence on the original stable kiss of valve core and valve seat, and when the turn-handle is released, the turn-handle can be restored with spring to close the valve by action of mass force so as to prevent water top from leaking.
一种无压不开的无泄阀,由装有套着隔开流体和传动件的翻卷式密封套的阀芯的阀体,和罩着并操纵弹簧等传动件不受外界干涉而且直接与阀体配合的盖帽式操作旋柄组成。其特征是:密封套与阀芯是可松紧的配合,阀芯分为头部和尾部两体,尾部与旋柄是弹性连接。无压时,旋升旋柄不影响阀芯原来已经稳稳地吻合阀座,当松开旋柄后,旋柄随弹簧复位并借助惯性力关闭阀门,避免了类似停水时忘关水龙头所引起的不良现象。
