GD型－高真空擋板閥 |
| |
| |
■ |
GD型高真空擋板閥用于接通或切斷真空管路中的氣流。適用介質(zhì)為純凈空氣和非腐蝕性氣體。高真空擋板閥按軸封結(jié)構(gòu)可分GD-J型橡膠軸封和GD-J(b)型波紋管軸封兩種。按通導(dǎo)形式可分GD-J為角通型式，GD-S為帶預(yù)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. |
