进口真空电磁压差充气阀外观精美-德国洛克

进口真空电磁压差充气阀产品概述：

德国《DE LOCKE》洛克进口真空电磁压差充气阀是安装在机械真空泵上，防止泵返油，避免泵油污染真空系统的专用真空阀门。该阀与泵接在同一电源上，当电磁阀关闭或突然断电时，阀利用大气压力差自动关闭真空系统，并对泵腔内充入大气。当通电时先导阀切断大气，真空泵抽气，阀板自动开启，真空系统正常工作。

适用的工作介质为空气及非腐蚀性气体。

Product overview of imported vacuum electromagnetic differential pressure inflation valve:

The vacuum electromagnetic differential pressure charging valve imported from Germany de lock is a special vacuum valve installed on the mechanical vacuum pump to prevent the pump from returning oil and prevent the pump oil from polluting the vacuum system. The valve and the pump are connected to the same power supply. When the solenoid valve is closed or suddenly powered off, the valve automatically closes the vacuum system by using the atmospheric pressure difference and fills the pump chamber with atmosphere. When energized, the pilot valve cuts off the atmosphere, the vacuum pump pumps air, the valve plate opens automatically, and the vacuum system works normally.

The applicable working medium is air and non corrosive gas.
