品牌：RETZ/我们一直致力于流体控制领域的持续创新，始于2005……进口高温电磁阀为先导活塞式结构,采用杠杆散热功能，原理保证线圈和阀体彻底隔离，提高了使用温度，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、中高温导热油、高温蒸汽、过热蒸汽等、电站抽气管道疏水系统和蒸发器的排气需要高温控制的系统中The RETZ high-temperature electromagnetic valve is a pilot piston type structure that uses a lever heat dissipation function to ensure complete isolation between the coil and valve body, increasing the operating temperature. It is widely used in bottle blowing machinery, air compressors, humidification equipment, high-temperature and high-pressure occasions, medium to high temperature hot water, medium to high temperature heat transfer oil, high-temperature steam, superheated steam, etc., as well as in systems that require high-temperature control for the drainage system of power station extraction pipelines and the exhaust of evaporators

进口高温电磁阀工作原理--Working principle of imported high-temperature 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

Normally open: When the coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, and the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed. When the coil is powered off, the pilot valve core is reset by the spring, 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 opens. Note: If the outlet pressure is greater than the inlet pressure, the medium will conduct in the opposite direction. Can be installed with a check valve
