进口防爆燃气电磁阀产品简介：

进口防爆燃气电磁阀是指用在燃气管线上，有防爆功能的，紧急切断，常开或者常闭式电磁阀。

Introduction of imported explosion proof gas solenoid valve products:
Imported explosion-proof gas solenoid valve is used in the gas pipeline, with explosion-proof function, emergency cut-off, normally open or normally closed solenoid valve.
 

进口防爆燃气电磁阀工作原理：

常闭：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。
     当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。
常开：当线圈通电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。
     当线圈断电时，先导阀芯靠弹簧复位，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。 

注：出口端压力大于进口端压力，介质会反向导通。可安装止回阀。

Working principle of imported explosion-proof gas solenoid valve:
Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
Normally open: when the coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
Note: if the outlet pressure is greater than the inlet pressure, the medium will conduct reversely. Check valves can be installed.
