产品结构设计特点Product structure design features

阀杆防吹出结构设计Valve stem anti-blowing structure design

阀杆防吹出结构设计,下端大上端小的阀杆在上端盖和螺丝的定位下,即使在阀腔异常的情况下,也能保证阀杆不会被介质吹出。retz品牌 Valve stem anti-blowing structure design, the lower end is larger and the upper end is smaller Under the positioning of the upper end cover and screws, even in the valve cavity is abnormal In the case of, it can also ensure that the valve stem will not be blown out by the medium.


防静电设计 Anti-static design 

固定球阀通过防静电设计使球体、阀杆、阀体形成静电通道。从而将球体与阀座开关过程中由于摩擦产生的静电通过阀体引到大地,防止静电火花可能引起防静电设计.jpg的火灾或爆炸危险。 The fixed ball valve adopts anti-static design to make the ball, stem and valve The body forms an electrostatic channel. So that the ball and the seat are switched During the process, static electricity generated by friction is led to the ground through the valve body,Prevent the risk of fire or explosion caused by static sparks.
