详细介绍

GD-J/S型高真空档板阀 GD High Vacuum Flapper Valve

GD型高真空挡板阀用于接通或切断真空管路中的气流。GD-J/S型高真空档板阀适用介质为纯净空气和非腐蚀性气体。高真空档板阀按轴封结构可分GD-J型橡胶轴封高真空档板阀和GD-J(b)型波纹管轴封高真空档板阀两种。高真空档板阀按通导形式可分GD-J为角通型式高真空档板阀，GD-S为带预抽口的三通型式高真空档板阀。

GD high vacuum flapper valves is used to put through or cut off the airflow in vacuum pipeline. Applicable medium can be pure air and noncorrosive gases. According to its shaft seal structure, high vacuum flapper valve is classified into GD-J rubber shaft seal type and GD-J(b)bellows shaft seal type. According to its put-through type, it is classified into GD-J angle type and GD-S three-way type with prepumping.
