进口低温电磁阀 液化气 液氨 液氮 LNG空分专用电磁阀的简单介绍

进口低温电磁阀 液化气 液氨 液氮 LNG空分专用电磁阀的详细信息

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……进口超低温电磁阀的阀杆为加长型,本产品通常用于LNG、液氧、乙醛、液氮、液氨、石油液化气、天然气、滤油机等易燃易爆等管路作自动化控制The valve stem of RETZ ultra-low temperature solenoid valve is an extended type. This product is usually used for automatic control of flammable and explosive pipelines such as LNG, liquid oxygen, acetaldehyde, liquid nitrogen, liquid ammonia, liquefied petroleum gas, natural gas, oil filters, etc.

液体、气体、油品可混合使用，提高阀的使用范围Liquid, gas, and oil can be mixed for use, increasing the range of use of the valve

进口超低温电磁阀工作原理--

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.
