DDC-JQ型电磁真空充气阀是安装在机械式真空泵上的专用阀门，适用介质为纯净空气和非腐蚀性气体，与泵同步开启和关闭，保护机械真空泵的安全。介绍电磁真空充气阀的型号规格、工作原理、技术参数、结构、外形尺寸。
高真空电磁阀
工作原理
电磁真空充气阀安装于机械真空泵的进气口，与泵接在同一电源上，泵的开启与停止直接控制了阀的开启与关闭。当泵停止工作或电源中断时，阀能自动将真空系统封闭，并将阀的充气孔打开，大气快速充入到泵腔，从而避免泵油逆流污染真空系统。

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.主要技术性能
