闸阀的优缺点有哪些

    闸阀具有以下优点Advantage of gate valve

    1、流体阻力小，密封面受介质的冲刷和侵蚀小。

    2、开闭较省力。

    3、介质流向不受限制，不扰流、不降低压力。

    4、形体简单，结构长度短，制造工艺性好，适用范围广。

    1、Small resistance to liquid,and small erosion to seal surface.

    2、Force saved to open and close.

    3、No limitation for the flow direction of medium,no blocking.no pressure reduction.

    4、Simple figure,short body,good craftwork,and extensive application range.

    闸阀的缺点如下Defect of gate valve

    1、密封面之间易引起冲蚀和擦伤，维修比较困难。

    2、外形尺寸较大，开启需要一定空间，开闭时间长。

    3、结构较复杂。

    1、Easy to cause the erosion and abrasion between seal surfaces,difficult to repair and maintain.

    2、Large external dimension,some space necessary to open,long time to open and close.

    3、Complicated structure
