DYC-JQ电磁真空压差阀概述

DYC-JQ电磁真空压差阀是机械真空泵安全阀o⊙⊙ω⊙ ▼,安装于机械真空泵的进气口o⊙⊙ω⊙ ▼,并与泵同步开启和关闭?!-!﹏▊。当泵停止工作或电源突然中断时o⊙⊙ω⊙ ▼,阀门利用大气压力使阀板自动关闭o⊙⊙ω⊙ ▼,使真空系统保持真空并将大气充入泵腔内o⊙⊙ω⊙ ▼,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.
