进口液氮用电磁阀结构特点：
1、经过低温深冷处理，能耐-196℃低温
2、设计、寿命超长 密封性好、开关迅速。
3、设计、外观精美；活塞结构 低温材料、密封性好线圈、不易烧毁。
4、阀芯均为不锈钢活塞式,活塞环用特殊耐低温、材料制作:活塞与金属阀腔不产生直接摩擦,阀体安装方向制；特制线圈,不易烧毁；长时间停止动作重新启动,作同样灵敏。
1. After cryogenic treatment, it can withstａnd - 196 ℃ low temperature
2. Unique design, long service life, stable performance, good sealing and quick switching.
3. Unique design, beautiful appearance; piston structure, stable performance; low temperature material, good sealing performance, autocratic coil, not easy to burn.
4. The valve core is stainless steel piston type, and the piston ring is made of special low temperature resistant and wear-resistant materials: the piston and metal valve chamber do not have direct friction, the installation direction of the valve body is unlimited; the special coil is not easy to burn; it stops and restarts for a long time, which is equally sensitive.
进口液氮用电磁阀工作原理：
常闭：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，阀腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。
常开：当线圈通电时，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。当线圈断电时，先导阀芯靠弹簧复位，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。
When the pressure of the pilot valve core is opened, the solenoid valve is closed by the pressure of the solenoid valve.
Normally open: when the coil is energized, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return 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 pressure in the upper chamber of the valve is released, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.
