工作原理 working principle

1.直动式电磁阀 Direct acting solenoid valve

原理：通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。

Principle: When energized, the electromagnetic coil generates electromagnetic force to lift the closing part from the valve seat, and the valve opens; When the power is cut off, the electromagnetic force disappears, and the spring presses the closing part against the valve seat, causing the valve to close

2.分步直动式电磁阀 Step-by-step direct acting solenoid valve

原理： 它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。

Principle: It is a combination of direct action and pilot type principle. When there is no pressure difference between the inlet and outlet, the electromagnetic force directly lifts the pilot small valve and the main valve closure part upwards after being energized, and the valve opens. When the starting pressure difference between the inlet and outlet is reached, after being energized, the electromagnetic force leads the small valve, causing the pressure in the lower chamber of the main valve to increase and the pressure in the upper chamber to decrease, thereby using the pressure difference to push the main valve upwards; When the power is cut off, the pilot valve uses spring force or medium pressure to push the closing element downwards, causing the valve to close.

3.先导式电磁阀 Pilot operated solenoid valve

在未通电时，呈关闭状态。当线圈通电时，产生电磁力使动铁芯和静铁芯吸合，导阀口打开，介质流向出口，此时主阀芯上腔的压力减小，低于进口侧的压力，形成压力差克服弹簧阻力而随之向上运动，达到开启主阀口的目的，介质流通。当线圈断电时，电磁力消失，动铁芯在弹簧力作用下复位关闭导阀口，此时介质从平衡孔流入，主阀芯上腔压力增大，并在弹簧力作用下向下运动，关闭主阀口

When not powered on, it is in a closed state. When the coil is energized, electromagnetic force is generated to cause the moving iron core and the static iron core to engage. The pilot valve port opens, and the medium flows to the outlet. At this time, the pressure in the upper chamber of the main valve core decreases, lower than the pressure on the inlet side, forming a pressure difference that overcomes the resistance of the spring and moves upwards, achieving the purpose of opening the main valve port, and the medium flows. When the coil is powered off, the electromagnetic force disappears, and the moving iron core resets and closes the pilot valve port under the action of spring force. At this time, the medium flows into the balance hole, and the pressure in the upper chamber of the main valve core increases. Under the action of spring force, it moves downward to close the main valve port
