一、V-GDQ型系列进口气动高真空挡板阀(带波纹管密封)概述

V-GDQ型系列气动高真空挡板阀(又称角阀)是用压缩空气为动力，通过电磁换向阀改变气路方向，推动气缸活塞上下运动，带动阀杆上下运动，使阀板开启或关闭，从而达到在真空系统中接通或切断气流的目的。V-GDQ-J型为角通型式，V-GDQ-S型为带预抽口的三通型式。适用的工作介质为空气及非腐蚀性气体。
注：其中DN400以上底部采用死法兰n-Mb。

The V-GDQ series pneumatic high vacuum baffle valve (also known as angle valve) is powered by compressed air and changes the direction of the air path through an electromagnetic directional valve, pushing the cylinder piston up and down and driving the valve stem up and down to open or close the valve plate, thereby achieving the purpose of connecting or cutting off the airflow in the vacuum system. The V-GDQ-J type is a corner pass type, and the V-GDQ-S type is a three-way type with a pre extraction port. The applicable working medium is air and non corrosive gases.

Note: For DN400 and above, a dead flange n-Mb is used at the bottom.
