摘要
介绍了一种硬密封球阀的结构,该球阀在阀座和球体间增加了螺线传动机构,阀门在启闭时,球体与阀座间无摩擦,延长了阀门的使用寿命,减小了启闭力矩。
Introduces the structure of a type of hard seal ball valve.This type of ball valve increases spire actuating mechanism between the seat and the sphere,when opening or closing,no friction occurs between the seat and the sphere.The working life of the valve is extended and opening or closing torque is decreased.
