DDC-JQ型电磁真空带充气阀
DDC-JQ型-电磁真空带充气阀概述
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或非腐蚀性气体。
DDC-JQ electromagnetic vacuum belt inflatable valve is a mechanical vacuum pump safety valve, installed in the mechanical vacuum pump inlet, and synchronously open and close with the pump. When the pump stops working or the power supply suddenly interrupts, the valve automatically closes, so that the vacuum system keeps vacuum and fills the air into the pump cavity, thereby avoiding the reverse flow of pump oil and polluting the vacuum system. The applicable medium is pure air or non corrosive gas.
