電磁(ci)閥概述  　

電磁(ci)閥   英(ying)文：solenoid valve 　　

電(dian)磁閥是用(yong)來(lai)控(kong)(kong)制流體的自動化基(ji)礎(chu)元件，屬(shu)于(yu)執(zhi)行器；并不限于(yu)液(ye)壓(ya)(ya)，氣動。 　　電(dian)磁閥用(yong)于(yu)控(kong)(kong)制液(ye)壓(ya)(ya)流動方向，工廠的機械裝置一般都(dou)由液(ye)壓(ya)(ya)缸控(kong)(kong)制，所以就(jiu)會(hui)用(yong)到電(dian)磁閥。

電磁(ci)閥工(gong)作原理

電(dian)(dian)磁閥(fa)(fa)里有(you)密閉(bi)的(de)(de)腔(qiang)，在不(bu)同位(wei)置(zhi)開有(you)通(tong)(tong)孔，每個孔都通(tong)(tong)向不(bu)同的(de)(de)油(you)管，腔(qiang)中間是閥(fa)(fa)，兩面是兩塊電(dian)(dian)磁鐵，哪(na)面的(de)(de)磁鐵線圈通(tong)(tong)電(dian)(dian)閥(fa)(fa)體(ti)就會被(bei)吸引(yin)到哪(na)邊，通(tong)(tong)過(guo)控(kong)(kong)制(zhi)閥(fa)(fa)體(ti)的(de)(de)移動(dong)來檔住(zhu)或(huo)漏出不(bu)同的(de)(de)排油(you)的(de)(de)孔，而進油(you)孔是常開的(de)(de)，液壓(ya)油(you)就會進入(ru)不(bu)同的(de)(de)排油(you)管，然(ran)后通(tong)(tong)過(guo)油(you)的(de)(de)壓(ya)力(li)來推動(dong)油(you)剛的(de)(de)活塞，活塞又帶動(dong)活塞桿(gan)，活塞竿(gan)帶動(dong)機(ji)械(xie)裝置(zhi)動(dong)。這樣通(tong)(tong)過(guo)控(kong)(kong)制(zhi)電(dian)(dian)磁鐵的(de)(de)電(dian)(dian)流就控(kong)(kong)制(zhi)了機(ji)械(xie)運動(dong)。
