进口带信号反馈电磁阀工作原理--Working principle of imported solenoid valve with signal feedback
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.

信号反馈:Signal feedback
当电磁阀打开时,信号公共线和开信号线接通 When the solenoid valve is opened, the signal common line and the open signal line are connected
当电磁阀关闭时,信号公共线和关信号线接通 When the solenoid valve is closed, the signal common line and the off signal line are connected
