品牌：RETZ瑞茨/我们一直致力于流体控制领域的持续创新，始于2005……进口带信号反溃功能电磁阀是一种能反映电磁阀是处于开或关状态的阀门,适合用于需检测介质是否流动的自动化管道系统,本产品广泛应用在石油化工、工业炉窑、锅炉、给排水、采暖空调、消防设备、干燥设备、食品设备、医疗设备、清洗设备、景观喷灌、石化、电力、化学、轻工、机械等自动化控制RETZ solenoid valve with signal anti collapse function is a valve that can reflect whether the solenoid valve is in an open or closed state. It is most suitable for automated pipeline systems that need to detect the flow of media. This product is widely used in petrochemical, industrial furnaces, boilers, water supply and drainage, heating and air conditioning, fire e, drying e, food e, medical e, cleaning e, landscape irrigation, petrochemical, power, chemical, light industry, etc Mechanical and other automation control

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
