The main valve, globe or angle pattern, is diaphragm actuated, hydraulically operated.
主阀，截止阀或角阀结构，采用隔膜驱动，液压操作。
Operating Principle: The diaphragm valve is a handwheel-operated valve, utilizing a two-piece stem separated by non perforated diaphragms. These diaphragms prevent leakage along the valve stem .
运转原理：膜板阀是一种手轮型阀门，它采用两个由非穿孔横膈膜隔开的阀杆。这些横膈膜防止了沿着阀杆的泄漏。
Operating Principle: The tied-diaphragm valve is a handwheel-operated valve, utilizing a two-piece stem connected through the diaphragms.
这是通过穿透横膈膜，把上下阀杆机械地连接在一起来实现的。
