进口水用电磁阀热水冷冻水不锈钢海水电磁阀

品牌：RETZ/我们一直致力于流体控制领域的持续创新，始于2005……进口水用电磁阀通常采用先导式结构,适用于中性纯净气体或液体、水、热水、冷冻水、循环水、除盐水、海水等管路的自动化控制系统,从而达到系统和设备的程序控制或远程控制The RETZ water solenoid valve usually adopts a pilot type structure and is suitable for automatic control systems of neutral pure gas or liquid, water, hot water, chilled water, circulating water, desalinated water, seawater, and other pipelines, in order to achieve program control or remote control of the system and equipment.
进口水用电磁阀控制原理--
常闭型：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 type: When the coil is energized, the pilot valve core is closed, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened; 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.
