闸阀的优点和缺点

闸阀的优点和缺点

原文:闸阀优点流体阻力小,密封面受介质的忡刷和侵蚀小。 开闭较省力。 介质流向不受限制,不扰流、不降低压力。形体简单,结构长度短,制造工艺性好,适用范围广。 闸阀缺点密封面之间易引起冲蚀和擦伤,维修比较困难。 外形尺寸较大,开启需要一定的空间,开闭时间长。 结构较复杂而且,由于该阀具备缓冲机构,能有效地减速轻了关闭阀门时,由于活塞下行冲击而造成的阀板车密封面和阀体密封面的磨损,同时,也能避免闸板卡死的现象。闸阀的优点和缺点?

译文:Valve advantages small fluid resistance, sealing surface Chong brush and erosion by the medium. Open and close more effort. Medium flow direction is not restricted, disturbed flow, reduce the pressure. Simple form, the structure length is short, make good manufacturability, scope of application is wide. Gate valve faults sealing surface, easy cause erosion and abrasion between maintenance more difficult. Needs certain space dimension is bigger, open, open and close time is long. Structure is relatively complex and, as a result of the valve has the buffering mechanism, can effectively slow down gently close the valve, due to the piston downward impact the scooter seal face and body sealing surface wear, at the same time, can also avoid the gate jammed phenomenon.闸阀的优点和缺点?
