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……进口油用电磁阀采用先导阀、活塞组合的结构设计,适用于导热油、润滑油、机油、柴油、汽油等常温介质在管路中的自动启闭，从而达到系统和设备的程序控制或远程控制The RETZ oil solenoid valve is designed with a combination of pilot valve and piston structure, suitable for automatic opening and closing of normal temperature media such as heat transfer oil, lubricating oil, engine oil, diesel, gasoline, etc. in pipelines, thus achieving program control or remote control of the system and equipment

进口油用电磁阀控制原理--

常闭：normal close

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
