工作原理：
Working principle.
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。
Normally closed: when the coil is energized, the solenoid core pull, pressure relief hole is opened, the main piston driven by the pressure of the medium, the main valve port is opened, the media flow.
当线圈断电时，主阀口关闭，介质截止。
When the coil power, the main valve port closed, medium s.
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。
Normally open: when the coil is energized, the solenoid core pull, pressure relief hole is closed, the main piston driven by the pressure of the medium, close the main valve port, media cutoff.
当线圈断电时，主阀口打开，介质流通。
When the coil power, the main valve port open, medium flow.
