摘要
介绍了一种能够大幅度减小承受介质进口压强的面积,从而减小阀门启闭扭矩的装置,解决了大口径调节阀和截止阀必须配置大型执行机构的问题。
Introduces a type of device which is able to significantly decrease the area of the inlet pres- sure of medium, accordingly to reduce the valve opening and closing torque. It solves the problem that large diameter reducing valves and globe valves must equipped with large actuators.
