DDC-JQ电磁真空带充气阀

DDC-JQ

DDC-JQ型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 openedclosed 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 vacuumthe 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 airnoncorrosive gases.
