氣(qi)動電磁(ci)閥工作原(yuan)理
氣動(dong)電磁(ci)(ci)閥(fa)里有(you)密閉的(de)(de)腔，在的(de)(de)不同位置開有(you)通孔，氣動(dong)電磁(ci)(ci)閥(fa)的(de)(de)每個孔都通向不同的(de)(de)油(you)管，腔中(zhong)間是(shi)閥(fa)，兩面是(shi)兩塊電磁(ci)(ci)鐵(tie)，哪面的(de)(de)磁(ci)(ci)鐵(tie)線圈通電閥(fa)體(ti)就(jiu)會(hui)被(bei)吸引到哪邊(bian)；
氣動(dong)電(dian)磁閥(fa)通過控(kong)制閥(fa)體的(de)移動(dong)來檔住(zhu)或(huo)漏(lou)出不(bu)(bu)同的(de)排油(you)(you)(you)的(de)孔，而進油(you)(you)(you)孔是常開的(de)，液壓(ya)油(you)(you)(you)就(jiu)會進入不(bu)(bu)同的(de)排油(you)(you)(you)管，然后通過氣動(dong)電(dian)磁閥(fa)的(de)油(you)(you)(you)的(de)壓(ya)力來推(tui)動(dong)油(you)(you)(you)剛(gang)的(de)活塞(sai)，這樣通過控(kong)制氣動(dong)電(dian)磁閥(fa)的(de)電(dian)磁鐵的(de)電(dian)流就(jiu)控(kong)制了整個電(dian)磁閥(fa)的(de)機(ji)械(xie)運動(dong)。
氣動電(dian)磁閥(fa)工作位(wei)置（也就是電(dian)磁閥(fa)的(de)開或(huo)關(guan)），就是在氣動電(dian)磁閥(fa)閥(fa)芯的(de)位(wei)置。電(dian)氣轉(zhuan)化組件(jian)將電(dian)訊(xun)號轉(zhuan)化為氣動訊(xun)號，再由電(dian)氣訊(xun)號輸入控制(zhi)氣動輸出。電(dian)磁閥(fa)根據命(ming)令執行空氣流(liu)向該釋放、改變還是停止。電(dian)磁閥(fa)中，電(dian)磁控制(zhi)換向閥(fa)是重要的(de)部件(jian)。
氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)磁(ci)閥(fa)主(zhu)要的(de)工作原理(li)是利(li)(li)(li)用(yong)電(dian)(dian)(dian)磁(ci)線圈中(zhong)產生的(de)電(dian)(dian)(dian)磁(ci)力推動(dong)(dong)(dong)(dong)(dong)閥(fa)芯切換(huan)，達到氣(qi)(qi)流(liu)換(huan)向目的(de)。也就是在氣(qi)(qi)動(dong)(dong)(dong)(dong)(dong)回路中(zhong)電(dian)(dian)(dian)磁(ci)閥(fa)控(kong)制(zhi)換(huan)向閥(fa)就是用(yong)來控(kong)制(zhi)氣(qi)(qi)流(liu)通(tong)道(dao)通(tong)過(guo)、截斷或改變壓(ya)縮空氣(qi)(qi)的(de)流(liu)動(dong)(dong)(dong)(dong)(dong)方(fang)向。按照(zhao)電(dian)(dian)(dian)磁(ci)閥(fa)控(kong)制(zhi)部分(fen)對換(huan)向閥(fa)的(de)推換(huan)方(fang)式來分(fen)直(zhi)動(dong)(dong)(dong)(dong)(dong)式電(dian)(dian)(dian)磁(ci)閥(fa)與先導式電(dian)(dian)(dian)磁(ci)閥(fa)。直(zhi)動(dong)(dong)(dong)(dong)(dong)式電(dian)(dian)(dian)磁(ci)閥(fa)可以直(zhi)接利(li)(li)(li)用(yong)電(dian)(dian)(dian)磁(ci)力推動(dong)(dong)(dong)(dong)(dong)閥(fa)芯的(de)換(huan)向，先導式電(dian)(dian)(dian)磁(ci)閥(fa)則是利(li)(li)(li)用(yong)電(dian)(dian)(dian)磁(ci)先導輸出的(de)先導氣(qi)(qi)壓(ya)來實現推動(dong)(dong)(dong)(dong)(dong)閥(fa)芯換(huan)向。
電(dian)磁(ci)閥(fa)(fa)的閥(fa)(fa)芯有(you)(you)開或關兩個(ge)不(bu)同(tong)的工(gong)作(zuo)位置(zhi)，這個(ge)便是二位電(dian)磁(ci)閥(fa)(fa)，對于(yu)氣(qi)動電(dian)磁(ci)閥(fa)(fa)來(lai)說(shuo)就是代表電(dian)磁(ci)閥(fa)(fa)處于(yu)帶電(dian)狀(zhuang)態和(he)失電(dian)狀(zhuang)態。二通(tong)(tong)(tong)(tong)和(he)三(san)通(tong)(tong)(tong)(tong)電(dian)磁(ci)閥(fa)(fa)就是指氣(qi)動電(dian)磁(ci)閥(fa)(fa)的閥(fa)(fa)體上(shang)有(you)(you)兩、三(san)個(ge)通(tong)(tong)(tong)(tong)道(dao)口。相同(tong)，三(san)通(tong)(tong)(tong)(tong)、四(si)通(tong)(tong)(tong)(tong)、五通(tong)(tong)(tong)(tong)也都(dou)是指電(dian)磁(ci)閥(fa)(fa)上(shang)的通(tong)(tong)(tong)(tong)道(dao)數(shu)。
