WDGD型－高真空挡板阀
WDGD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WDGD-J型橡胶轴封和WDGD-J(b)型波纹管轴封两种。按通导形式可分WDGD-J为角通型式，WDGD-S为带预抽口的三通型式。
WDGD High Vacuum Flapper Valve
WDGD 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 structure, high vacuum flapper valve is classified into WDGD-J rubber shaft seal type and WDGD-J(b)bellows shaft seal type. According to its put-through type, it is classified into WDGD-J angle type and WDGD-S three-way type with prepumping.
