  刀型闸阀的启闭件是闸板,闸板的运动方向与流体方向相垂直,靠可以切割纤维材料的刀刃形闸板来切断介质,闸板有两个密封面,常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异,通常为5°,楔式刀型闸阀的闸板可以做成一个整体,叫做刚性闸板;也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板。阀体实际上不存在腔室,闸板在侧面导向槽内升降,并由底部的凸耳紧压在阀座上,如需达到较高的介质密封性时,可选用O形密封阀座实现双向密封。

  The Opening And Closing Part Of The Knife Gate Valve Is The Gate. The Movement Direction Of The Gate Is Perpendicular To The Direction Of The Fluid. The Medium Is Cut Off By The Blade Shaped Gate Which Can Cut The Fiber Material. The Gate Has Two Sealing Surfaces. The Wedge Angle Of The Two Sealing Surfaces Of The Common Mode Gate Valve Varies With The Valve Parameters, Which Is Usually 5 ° And Can Be Made Into A Whole, Called Rigid Gate; In The Process Of Making The Ram, It Can Make Up For The Deviation Of The Angle Of The Ram, Which Can Also Be Produced In The Process Of Processing. In Fact, There Is No Chamber In The Valve Body. The Gate Plate Rises And Falls In The Side Guide Groove, And Is Pressed Tightly On The Valve Seat By The Lug At The Bottom. If High Medium Sealing Performance Is Required, O-shaped Sealing Seat Can Be Selected To Realize Bidirectional Sealing.
