进口铸钢丝扣闸阀

德国巴赫进口铸钢丝扣闸阀概述：Introduction of Bach steel wire gate valve imported from germany:

进口铸钢丝扣闸阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。当介质由阀瓣下方进入阀体时，操作力所需要克服的阻力，是阀杆和填料的磨擦力与由介质的压力所产生的推力，关阀门的力比开阀门的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。

Imported steel wire buckle gate valve

Germany Bach imported steel wire buckle gate valve overview:

Imports of cast steel gate valve is a mandatory seal valve, so the valve is closed, the valve must be applied to force the sealing surface does not leak. When the medium into the valve body from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault.

进口铸钢丝扣闸阀的定义：Definition of imported cast steel wire buckle gate valve:

2.工作行程小，启闭时间短。
3.密封性好，密封面间磨擦力小，寿命较长。

Definition of imported steel wire buckle gate valve:

1 simple structure, easy to manufacture and maintenance.

2 working stroke is small, open and close time is short.

3 good sealing, sealing surface friction between small, long life.
