GD型高bf88挡板阀概述

。高bf88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。

High Vacuum Flapper Valve

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 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.
