DDC-JQ型－电磁真空带充气阀_真空阀_江苏德美特真空阀门制造有限公司

DDC-JQ型电磁真空带充气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。


■  DDC-JQ
Electro-vacuum  Charging  Valve

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