进口低温防爆电磁阀德国LOCKE洛克参数尺寸图片
进口低温防爆电磁阀作原理：
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。

Working principle of imported low temperature explosion-proof solenoid valve:
Normally closed: when the coil is energized, the pilot valve core is pulled in, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, 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, the valve chamber is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed.

Product introduction of imported low temperature explosion-proof solenoid valve:
The low-temperature explosion-proof solenoid valve imported from Germany de lock refers to the valve whose connecting terminal meets the electrical explosion-proof requirements to prevent the explosion of combustible and explosive gases. The valve core is made of low-temperature cryogenic treated stainless steel, the seal is made of special low-temperature resistant materials, and the minimum temperature can reach - 196 degrees. The valve switch is driven by a coil, which can realize the remote automatic control of low-temperature medium, It is applicable to the opening and closing of liquid nitrogen, liquid ammonia, liquid oxygen, liquid argon, liquefied natural gas, LNG and low-temperature refrigerant.
