进口带信号反馈电磁阀 不锈钢信号电磁阀 美国RETZ瑞茨品牌

　　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,最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RETZsolenoid valve with signal anti collapse function is a valve that can reflectwhether the solenoid valve is in an open or closed state. It is most suitablefor automated pipeline systems that need to detect the flow of media. Thisproduct is widely used in petrochemical, industrial furnaces, boilers, watersupply and drainage, heating and air conditioning, fire equipment, dryingequipment, food equipment, medical equipment, cleaning equipment, landscapeirrigation, petrochemical, power, chemical, light industry, etc Mechanical andother automation control

　　进口带信号反馈电磁阀工作原理--Workingprinciple 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。

　　Normallyclosed: When the coil is energized, the pilot valve core is closed, the pilothole opens, the upper chamber of the valve is depressurized, the piston ispushed by the medium pressure in the lower chamber, and the solenoid valveopens. When the coil is powered off, the pilot valve core is reset by thespring, the pilot hole is closed, and the valve upper chamber is pressurized bythe piston orifice and the thrust of the reset spring, and the solenoid valveis closed.
