一、进口焊接高真空隔膜阀概述
V-GM型系列高真空隔膜阀是利用阀杆将橡胶膜直接压在阀座上，用来截止或接通真空系统。采用连接形式有活套法兰连接、快卸法兰连接、焊接式连接。焊接式连接又分焊接式I型连接(即两端焊接)，焊接式II型连接(即一端焊接，另一端插入)。
阀门适用的工作介质为空气及非腐蚀性气体。

The V-GM series high vacuum diaphragm valve uses the valve stem to directly press the rubber film onto the valve seat, used to cut off or connect the vacuum system. The connection forms used include sleeve flange connection, quick release flange connection, and welded connection. Welded connections can be divided into welded Type I connections (i.e. welded at both ends) and welded Type II connections (i.e. welded at one end and inserted at the other end).

The working medium suitable for valves is air and non corrosive gases.
