三、进口燃气紧急切断电磁阀工作原理：

1、阀门在日常工作中处于常开状态，电磁阀线圈处于断电状态，不消耗电能；

2、当事故发生时，阀门线圈瞬时通电，触发阀门快速关闭，并进入自锁状态。此时即使撤去电源，阀门仍处于自锁关闭状态，不会重新自动打开；

3、本阀采用先导式阀瓣，开启轻松，即使压力达到6bar开启也十分轻松，口径大于DN125，采用杠杆手柄，使本阀达到目的开关省力、快速；

4、当工作人员处理完事故，人工重新开启阀门，才会恢复供气。

3、 Working principle of imported gas emergency shut-off solenoid valve:

1. The valve is normally open in daily work, and the solenoid valve coil is in power-off state, which does not consume electric energy;

2. When the accident occurs, the valve coil is energized instantaneously, which triggers the valve to close quickly and enter the self-locking state. At this time, even if the power supply is removed, the valve is still in the self-locking closed state and will not automatically open again;

3. The valve adopts the pilot valve disc, which is easy to open, even if the pressure reaches 6bar, the opening is also very easy. The diameter is larger than DN 125, and the lever handle is used to make the valve achieve the goal of labor-saving and fast opening and closing;

4. When the staff deal with the accident, manually re open the valve, the gas supply will be restored.

四、进口燃气紧急切断电磁阀性能特点：

通用性广、灵敏性高、严密性强、安全性高、寿命性长
