ATOS電磁換向閥里有密閉的腔，在不同位置開有通孔，每個孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來開啟或關閉不同的排油孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過油的壓力來推動油缸的活塞，活塞又帶動活塞桿，活塞桿帶動機械裝置。這樣通過控制電磁鐵的電流通斷就控制了機械運動。 ATOS電磁閥主要分類: 1、ATOS電磁閥從(cong)原理上分為三大類： 1）ATOS直動式電磁閥： ATOS電(dian)磁閥(fa)原理：通(tong)電(dian)時，電(dian)磁線圈產生電(dian)磁力把關閉(bi)件(jian)從閥(fa)座(zuo)(zuo)上提起，閥(fa)門打開；斷電(dian)時，電(dian)磁力消失，彈簧把關閉(bi)件(jian)壓在閥(fa)座(zuo)(zuo)上，閥(fa)門關閉(bi)。 ATOS電磁閥特點：在真空(kong)、負壓、零壓時能正(zheng)常工作，但(dan)通徑一般不超(chao)過25mm。 2）分(fen)步直動式電磁閥： ATOS電磁閥(fa)(fa)原理：它是一(yi)種(zhong)直(zhi)動和先導式相結合(he)的原理，當入口與(yu)出(chu)口沒有壓(ya)(ya)差時(shi)，通電后，電磁力(li)直(zhi)接把先導小(xiao)閥(fa)(fa)和主(zhu)閥(fa)(fa)關閉(bi)件依次向(xiang)(xiang)上(shang)提起(qi)，閥(fa)(fa)門(men)打開(kai)。當入口與(yu)出(chu)口達到啟動壓(ya)(ya)差時(shi)，通電后，電磁力(li)先導小(xiao)閥(fa)(fa)，主(zhu)閥(fa)(fa)下腔(qiang)(qiang)壓(ya)(ya)力(li)上(shang)升，上(shang)腔(qiang)(qiang)壓(ya)(ya)力(li)下降，從而(er)利用壓(ya)(ya)差把主(zhu)閥(fa)(fa)向(xiang)(xiang)上(shang)推(tui)(tui)開(kai)；斷電時(shi)，先導閥(fa)(fa)利用彈簧力(li)或介質(zhi)壓(ya)(ya)力(li)推(tui)(tui)動關閉(bi)件，向(xiang)(xiang)下移動，使閥(fa)(fa)門(men)關閉(bi)。 ATOS電磁閥特(te)點：在(zai)零壓差或真空、高(gao)壓時亦能可(ke)*動作，但功(gong)率較(jiao)大，要求(qiu)必須水平安裝。 3）先(xian)導式電磁(ci)閥： ATOS電(dian)(dian)(dian)磁閥(fa)原理：通(tong)電(dian)(dian)(dian)時，電(dian)(dian)(dian)磁力(li)把先導孔打(da)開(kai)(kai)，上腔室壓(ya)(ya)力(li)迅速下降，在關 閉(bi)件周(zhou)圍形(xing)成上低下高(gao)的壓(ya)(ya)差，流體壓(ya)(ya)力(li)推動(dong)關閉(bi)件向(xiang)上移(yi)(yi)動(dong)，閥(fa)門打(da)開(kai)(kai)；斷電(dian)(dian)(dian)時，彈簧力(li)把先導孔關閉(bi)，入(ru)口壓(ya)(ya)力(li)通(tong)過旁通(tong)孔迅速腔室在關閥(fa)件周(zhou)圍形(xing)成下低上高(gao)的壓(ya)(ya)差，流體壓(ya)(ya)力(li)推動(dong)關閉(bi)件向(xiang)下移(yi)(yi)動(dong)，關閉(bi)閥(fa)門。 ATOS電磁(ci)閥(fa)特點：流體壓(ya)力范(fan)圍上限(xian)較(jiao)高，可(ke)任意安裝(zhuang)（需(xu)定制(zhi)）但(dan)必須滿(man)足(zu)流體壓(ya)差條件(jian)。 2、電磁閥從閥結構(gou)和材(cai)料(liao)上(shang)的不同與原理上(shang)的區別，分(fen)(fen)為(wei)六個分(fen)(fen)支小(xiao)類：直(zhi)(zhi)動膜片結構(gou)、分(fen)(fen)步(bu)直(zhi)(zhi)動膜片結構(gou)、先導(dao)膜片結構(gou)、直(zhi)(zhi)動活塞結構(gou)、分(fen)(fen)步(bu)直(zhi)(zhi)動活塞結構(gou)、先導(dao)活塞結構(gou)。 ; 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)按(an)照功能(neng)分類：水用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、蒸汽(qi)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、制冷電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、低溫電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、燃氣(qi)(qi)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、消(xiao)防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、氨用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、氣(qi)(qi)體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、液(ye)體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、脈沖電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、液(ye)壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa) 常(chang)開電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、油用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、直流電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、高(gao)壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)、防爆(bao)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)等。 意大利ATOS電磁閥型號表： DHI-0713-X 24DC
