一、进口空气电磁阀产品概述：

德国《LOCKE》洛克--进口真空电磁阀是安装在机械式真空泵上的专用阀门。阀门与泵接在同一电源上，泵的开启与停止直接控制了阀的开启与关闭。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，并将大气通过泵的进气口充入泵腔，避免泵油返流污染真空系统。真空电磁阀适用的工作介质为空气及非腐蚀性气体。

1、 Introduction of imported air solenoid valve products:

German "Locke" - imported vacuum solenoid valve is a special valve installed on mechanical vacuum pump. The valve and the pump are connected to the same power supply, and the opening and stopping of the pump directly controls the opening and closing of the valve. When the pump stops working or the power supply is suddenly interrupted, the valve can automatically close the vacuum system, and fill the air into the pump cavity through the air inlet of the pump, so as to avoid the pump oil backflow polluting the vacuum system. The working medium of vacuum solenoid valve is air and non corrosive gas.

三、进口空气电磁阀工作原理：

常闭：当线圈通电时，电磁铁芯吸合，卸压孔打开，主活塞由介质压力推动，打开主阀口，介质流通。

当线圈断电时，主阀口关闭，介质截止。

常开：当线圈通电时，电磁铁芯吸合，卸压孔关闭，主活塞由介质压力推动，关闭主阀口，介质截止。

当线圈断电时，主阀口打开，介质流通。

3、 Working principle of inlet air solenoid valve:

Normally closed: when the coil is energized, the electromagnet core is closed, the pressure relief hole is opened, the main piston is pushed by the medium pressure, the main valve port is opened, and the medium flows.

When the coil is powered off, the main valve port is closed and the medium is cut off.

Normally open: when the coil is energized, the electromagnet core is closed, the pressure relief hole is closed, the main piston is pushed by the medium pressure, the main valve port is closed, and the medium is cut off.

When the coil is powered off, the main valve port opens and the medium flows.
