NKZ41/44H/Y真空隔断手动闸阀 №:148

Vacuum Partition Manual Gate Valve

1、本系列阀门主体采用铸锻结构，具有平行双密封副半强制双向密封，密封面到位运动和楔形块楔紧运动分步作用，实现零泄漏。

2、密封面之间摩擦系数小，启闭方便，而且，密封面的磨损有自动补偿功能。

3、结构简单，紧凑，检修方便，使用寿命长。

1.The main body of this series of valves adopts Cast forging structure,with parallel double sealing pairs,semi forced iwo-way sealing,step-by-step movementof sealing surface in place and wedge-shaped bleck wedging funetion to achieve zero leakage.

2.The friction coefficient between the sealing surfaces is small,the opening and closing is convenient,and the wear of the sealing surfacehas the function of automatic compensation.

3.The utility medel has the advantages of simpte and compact structure,convenient maintenance and long service life.
