：RETZ瑞茨/我们一直致力于流体控制领域的持续，始于2005……进口制冷电磁阀适用于氟利昂、制冷剂、水、冷冻液、气为工作介质，实现通断自动化，具有启阀迅速，性能稳定，使用方便，节能好，寿命长等优点Retz refrigeration solenoid valve is suitable for working media such as Freon, refrigerant, water, refrigerant, and gas, achieving automatic on-off. It has the advantages of quick valve opening, stable performance, convenient use, good energy conservation, and long service life
进口制冷剂电磁阀控制原理--
常闭式：Normally closed
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
