直动式电磁阀原理: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。特点:在真空、负压、零压时能正常工作,但通径-般不超过2

5mm。分步直动式电磁阀原理: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。特点:在零压差或真空、高压时亦能可*动

作,但功率较大,要求必须水平安装。先导式电磁阀原理:通电时,电磁力把先导孔打开，上腔室压力迅

速下降，在关闭件周围形成上低下高的压差,流体压力推动关闭件向上移动,阀门打开;断电时,弹簧力

把先导孔关闭,入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差,流体压力推动关闭件向

下移动，关闭阀门。特点:流体压力范围上限较高，可任意安装(需定制)但必须满足流体压差条件。

2、电磁阀从阀结构和材料上的不同与原理上的区别,分为六个分支小类:直动膜片结构、分步直动膜片结

Festo FESTO solenoid valve 566496 VUVG-L14-T32C-AT-G18-1P3

Principle of direct acting solenoid valve: When energized, the electromagnetic coil generates electromagnetic force to lift the closing part from the valve seat, and the valve opens; When power is cut off, electromagnetic force is dissipated

The spring presses the closing element against the valve seat, causing the valve to close. Characteristics: It can work normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 2

5mm。 Principle of step-by-step direct acting solenoid valve: It is a combination of direct acting and pilot operated principle, which is energized when there is no pressure difference between the inlet and outlet

Afterwards, the electromagnetic force directly lifts the pilot small valve and the main valve closure piece upwards, and the valve opens. When the starting pressure difference between the inlet and outlet is reached, power on

Afterwards, 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; During power outage, the pilot

The valve uses spring force or medium pressure to push the closing element downwards, causing the valve to close. Features: It can also be operated at zero pressure difference, vacuum, and high pressure

However, due to its high power, it is required to be installed horizontally. Principle of pilot operated solenoid valve: When energized, electromagnetic force opens the pilot hole and the upper chamber pressure is rapid
