进口高温电磁阀

进口高温电磁阀工作原理--Working principle of imported high-temperature solenoid valve

常闭式：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。

Normally closed: When the coil is energized, the pilot valve core is closed, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens. When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, and the valve upper chamber is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

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

Normally open: When the coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, and 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 upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens. Note: If the outlet pressure is greater than the inlet pressure, the medium will conduct in the opposite direction. Can be installed with a check valve
