  旋塞阀是用带通孔的塞体作为启闭件的阀门。塞体随阀杆转动,以实现启闭动作。小型无填料的旋塞阀又称为“考克”。旋塞阀的塞体多为圆锥体(也有圆柱体),与阀体的圆锥孔面配合组成密封副。旋塞阀结构简单、开关迅速、流体阻力小。普通旋塞阀的金属塞体与阀体间的直接接触来密封,所以密封性较差,启闭力大,容易磨损,通常只能用于低压(不高于1兆帕)和小口径(小于100毫米)的场合。

  The Plug Valve Is A Valve Which Uses The Plug Body With Through Hole As The Opening And Closing Parts. The Plug Body Rotates With The Valve Stem To Realize The Opening And Closing Action. Small Non Packing Plug Valve Is Also Known As "cock". The Plug Body Of The Plug Valve Is Mostly A Cone (or A Cylinder), Which Is Matched With The Conical Hole Surface Of The Valve Body To Form A Sealing Pair. The Plug Valve Has The Advantages Of Simple Structure, Quick Switch And Small Fluid Resistance. The Metal Plug Of Ordinary Plug Valve Is Sealed By Direct Contact Between The Metal Plug Body And The Valve Body, So The Sealing Performance Is Poor, The Opening And Closing Force Is Large, And It Is Easy To Wear. It Can Only Be Used In Low Pressure (no More Than 1 Mpa) And Small Diameter (less Than 100 Mm).
