三、进口消防电磁阀工作原理：

当自动控制时：常闭式-手动开关指向关：线圈通电，电磁阀打开;线圈断电，电磁阀关闭。常开式-手动开关向开的方向旋转2~4圈，电磁阀不通电为打开状态。当线圈通电时，阀关闭。

当手动控制时：旋转手动开关，常闭式手动开关指向开的方向(常开式向开的方向旋转2~4圈)电磁阀打开，介质流通;旋转手动开关，常闭式手动开关指向关的方向(常开式向关的方向旋转到不动为止)电磁阀关闭，介质截止。

3、 Working principle of imported fire solenoid valve:

When the automatic control: normally closed - manual switch to close: coil power, solenoid valve open; The coil is de energized and the solenoid valve is closed. Normally open - the manual switch rotates 2 ~ 4 turns in the open direction, and the solenoid valve is in the open state when it is not energized. When the coil is energized, the valve closes.

When the manual control: rotate the manual switch, the normally closed manual switch points to the open direction (the normally open direction rotates 2 ~ 4 circles), the solenoid valve opens, and the medium flows; Rotate the manual switch, the normally closed manual switch points to the off direction (normally open to the off direction until it does not move), the solenoid valve is closed, and the medium is cut off.

四、进口消防电磁阀性能特点：

1.阀体、阀盖、阀芯、阀杆等与水接触的零部件均为SS304不锈钢或不锈钢304，防腐防锈；

2.磁芯管、动铁芯、不锈钢复位弹簧均与水隔绝，防水蚀、防水垢，消除了被水垢卡死而失灵的风险；

3.不锈钢阀芯刚性好、强度高，避免了塑料阀芯受压、受保压水温升高等产生的变形，消除了因塑料阀芯变形可能引起的关不严、或卡死故障因的可能性；

4.不锈钢弹簧置于阀盖顶的一个密闭外腔内，防尘防杂质卡死；

5.特制专用电磁线圈，在长期放置不使用情况下，仍能保持性能稳定可靠；

6.用防爆电磁阀线圈替换普通非防爆电磁线圈即为防爆消防电磁阀；

7.可以订制带手动装置的防爆消防电磁阀。

4、 Performance characteristics of imported fire solenoid valve:

1. Valve body, valve cover, valve core, valve stem and other parts in contact with water are SS304 stainless steel or stainless steel 304, anti-corrosion and anti rust;

2. The magnetic core tube, moving core and stainless steel return spring are all isolated from water to prevent corrosion and scale, thus eliminating the risk of failure caused by scale jamming;

3. The stainless steel valve core has good rigidity and high strength, which can avoid the deformation of plastic valve core caused by pressure and high temperature rise under pressure, and eliminate the possibility of loose closing or stuck fault caused by plastic valve core deformation;

4. The stainless steel spring is placed in a closed outer chamber on the top of the valve cover to prevent dust and impurities from jamming;

5. The special electromagnetic coil can keep stable and reliable performance when it is not used for a long time;

6. Replace the ordinary non explosion proof solenoid with the explosion-proof solenoid, that is, the explosion-proof fire-fighting solenoid;

7. Explosion proof fire solenoid valve with manual device can be customized.
