■	GD型－高真空挡板阀
&sp;
&sp;	■	GD型高真空挡板阀用于接通或切断真空管路中的气流。适用介质为纯净空气和非腐蚀性气体。高真空挡板阀按轴封结构可分GD-J型橡胶轴封和GD-J(b)型波纹管轴封两种。按通导形式可分GD-J为角通型式，GD-S为带预抽口的三通型式。

■	GD High Vacuum Flapper Valve
&sp;
&sp;	■	GD high vacuum flapper valve 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 struure, high vacuum flapper valve is clified into GD-J rubber shaft seal te and GD-J(b)bellows shaft seal te. According to its put-through te, it is clified into GD-J angle te and GD-S three-way te with prepumping.
