进口楔式闸阀的密封原理你们知道吗？

原文：
楔式闸阀的密封原理:
它是靠楔形闸板上的两密封面和阀体上的两密封面楔人时的 紧密结合来达密封的。使用楔形闸板的目的是为了提高辅助 的密封载荷，以使金属密封的楔式闸阀既能对高介质压力， 也能对低介质压力进行密封。关闭时顺时针旋转阀杆，使闸 板密封面和阀体密封面密合而达到密封。但是，金属密封的 楔式闸阀由楔入作用所产生的进口端密封比压受到介质的作 用力往往不足以达到进口端密封。所以说金属密封楔式闸阀 属单面强制密封。

Wedge gate valve sealing principle: 
It is to rely on wedge two seal face and body on the sealing surface on the wedge person together to seal. Is the purpose of using the wedge in order to improve the sealing of secondary load, in order to make the metal sealing wedge gate valve can not only for high pressure of medium, low to medium pressure to seal. Closing clockwise rotate the valve stem, to sealing face seal face and body gate is closed and sealed. But the metal seal of wedge gate valve produced by wedging effect of inlet side sealing pressure forces are often not enough to achieve by medium inlet side seal. So the metal sealing wedge gate valve is a single seal
