真空电磁阀DDC，DQC
所属类目：电磁阀系列
产品简介：DDC，DQC真空电磁阀是安装在机械真空泵上的专用阀门，并与泵接在同一个电源上，泵的开启与停止直接控制阀门的开启与关闭。当泵停止工作或电源突然中断时，阀能自动将真空系统封闭，并将大气通过 阀的充气口经阀充入到泵腔，从而避免泵油逆流污染真空系统。
DDC-JQ电磁真空带充气阀
DDC-JQ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-JQElectro-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.
