品牌：RETZ/我们一直致力于流体控制领域的持续创新，始于2005……进口高压电磁阀通常为活塞式结构,广泛应用于吹瓶机械、空压机、加湿设备、高温高压场合、中高温热水、导热油、高温蒸汽、饱和蒸汽及过热蒸汽等需要高压控制的系统中 The Retz high-pressure solenoid valve is usually a piston type structure and is widely used in systems that require high-pressure control, such as bottle blowing machinery, air compressors, humidification equipment, high-temperature and high-pressure occasions, medium and high temperature hot water, thermal oil, high-temperature steam, saturated steam, and superheated steam, etc

进口高压电磁阀工作原理--Working principle of imported high-pressure solenoid valve

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.

注：出口端压力大于进口端压力，介质会反向导通。可安装止回阀。
