DYC-JQ型－电磁真空压差阀_真空阀_江苏德美特真空阀门制造有限公司

  DYC-JQ型电磁真空压差阀是机械真空泵安全阀，安装于机械真空泵的进气口，并与泵同步开启和关闭。当泵停止工作或电源突然中断时，阀门利用大气压力使阀板自动关闭，使真空系统保持真空并将大气充入泵腔内，从而避免泵油逆向流动而污染真空系统。适用介质为纯净空气和非腐蚀性气体。


■  DYC-JQ
Electro-vacuum  Differential  Pressure  Valve

    ■  DYC-JQ  electro-vacuum  differential  Pressure  valve  is  a  safely  valve  for  mechanical  vacuum  pump.  It  is  mounted  at  the  intake  nozzle  of  mechanical  vacuum  pump,  synchronously  opened  and  closed  with  the  pump.  In  case  that  pump  stops  working  or  power  supply  is  suddenly  broken  off,  valve  disc  will  be  closed  automatically  under  atmospheric  pressure,  to  keep  the  vacuum  system  vacuum  and  the  air  charged  into  pump  cavity,  thus  to  prevent  pump  oil  from  reverse  flow  that  can  pollute  the  vacuum  system.  Applicable  medium  can  be  pure  air  or  noncorrosive  gases.
