      WDGD型-高真空擋板閥
      WDGD型高真空擋板閥用于接通或切斷真空管路中的氣流。適用介質為純凈空氣和非腐蝕性氣體。高真空擋板閥按軸封結構可分WDGD-J型橡膠軸封和WDGD-J(b)型波紋管軸封兩種。按通導形式可分WDGD-J為角通型式,WDGD-S為帶預抽口的三通型式。
      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.
