DYC-JQ电磁真空压差阀

DYC-JQ电磁真空压差阀概述

DYC-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，阀门利用大气压力使阀板自动关闭，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。

DYC-JQ

Electro-vacuum Differential Pressure Valve

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