工作原理 working principle

有常闭和常开型二种 There are two types: normally closed and normally open

常闭型:采用一次开阀和二次开阀集于一体的形式,主阀和导阀分步有电磁力和压力差作用来直接开启主阀口。当线圈通电时,产生电磁力使动铁芯和静铁芯吸合,导阀口开启,而导阀口设在主阀口上,动铁芯与主阀芯连在一起,此时主阀上腔的压力通过导阀口卸荷,在压力差和电磁力的同时作用下,使用主阀芯向上运动,开启主阀口,介质流通。当线圈断电时电磁力消失,此时动铁芯在自重和弹簧力的作用下关闭导阀孔,介质在平衡孔中进入主阀上腔,使上腔压力升高,此时在弹簧复位和压力作用下关闭主阀口,介质断流。

进口内螺纹零压差电磁阀结构图.jpgNormally closed type: Adopting a combination of primary and secondary opening valves, the main valve and pilot valve have electromagnetic force and pressure difference in steps to directly open the main valve port. When the coil is energized, electromagnetic force is generated to cause the moving iron core and the static iron core to engage, and the pilot valve port is opened. The pilot valve port is located on the main valve port, and the moving iron core is connected to the main valve core. At this time, the pressure in the upper chamber of the main valve is unloaded through the pilot valve port. Under the simultaneous action of pressure difference and electromagnetic force, the main valve core is moved upwards, opening the main valve port, and the medium flows. When the coil loses power, the electromagnetic force disappears. At this time, the moving iron core closes the pilot valve hole under the action of its own weight and spring force, and the medium enters the upper chamber of the main valve in the balance hole, causing the pressure in the upper chamber to increase. At this time, the main valve port is closed under the action of spring reset and pressure, and the medium is cut off

常开型:与常闭型正好相反 Normally open type: exactly opposite to normally closed type
