ATOS電磁閥里有密閉的腔，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(ci)閥從原理(li)上分(fen)為(wei)三大類： 1）ATOS直(zhi)動式電磁(ci)閥： ATOS電(dian)(dian)(dian)磁閥(fa)(fa)原理：通(tong)電(dian)(dian)(dian)時，電(dian)(dian)(dian)磁線(xian)圈(quan)產生電(dian)(dian)(dian)磁力(li)把關閉(bi)件從閥(fa)(fa)座上提(ti)起，閥(fa)(fa)門(men)打(da)開；斷電(dian)(dian)(dian)時，電(dian)(dian)(dian)磁力(li)消失，彈簧把關閉(bi)件壓在閥(fa)(fa)座上，閥(fa)(fa)門(men)關閉(bi)。 ATOS電磁閥特點(dian)：在真空、負壓、零壓時能正常工作，但(dan)通徑一(yi)般不超過25mm。 2）分步(bu)直動式電磁閥： ATOS電磁(ci)閥(fa)(fa)原理(li)(li)：它是一種直動(dong)(dong)和先(xian)導(dao)式相結合的原理(li)(li)，當(dang)入(ru)口與出(chu)口沒(mei)有(you)壓(ya)(ya)差時(shi)，通(tong)電后，電磁(ci)力(li)(li)直接把先(xian)導(dao)小(xiao)閥(fa)(fa)和主閥(fa)(fa)關閉(bi)件(jian)依(yi)次向上(shang)提起，閥(fa)(fa)門(men)打(da)開。當(dang)入(ru)口與出(chu)口達到啟動(dong)(dong)壓(ya)(ya)差時(shi)，通(tong)電后，電磁(ci)力(li)(li)先(xian)導(dao)小(xiao)閥(fa)(fa)，主閥(fa)(fa)下腔(qiang)壓(ya)(ya)力(li)(li)上(shang)升(sheng)，上(shang)腔(qiang)壓(ya)(ya)力(li)(li)下降，從而(er)利用壓(ya)(ya)差把主閥(fa)(fa)向上(shang)推開；斷電時(shi)，先(xian)導(dao)閥(fa)(fa)利用彈簧(huang)力(li)(li)或介(jie)質壓(ya)(ya)力(li)(li)推動(dong)(dong)關閉(bi)件(jian)，向下移(yi)動(dong)(dong)，使閥(fa)(fa)門(men)關閉(bi)。 ATOS電磁閥特點：在(zai)零壓(ya)差或真空、高壓(ya)時亦(yi)能可(ke)*動作，但功率較(jiao)大，要求必須水平安裝(zhuang)。 3）先導式電磁閥(fa)： ATOS電(dian)(dian)(dian)磁閥(fa)原理：通電(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)磁力(li)(li)把(ba)先導孔打(da)開，上腔(qiang)室(shi)壓(ya)力(li)(li)迅速下(xia)降，在關(guan) 閉(bi)(bi)件周圍(wei)形成(cheng)上低(di)下(xia)高(gao)的壓(ya)差(cha)，流(liu)體(ti)壓(ya)力(li)(li)推(tui)(tui)動(dong)關(guan)閉(bi)(bi)件向上移動(dong)，閥(fa)門打(da)開；斷電(dian)(dian)(dian)時(shi)，彈簧力(li)(li)把(ba)先導孔關(guan)閉(bi)(bi)，入口壓(ya)力(li)(li)通過旁(pang)通孔迅速腔(qiang)室(shi)在關(guan)閥(fa)件周圍(wei)形成(cheng)下(xia)低(di)上高(gao)的壓(ya)差(cha)，流(liu)體(ti)壓(ya)力(li)(li)推(tui)(tui)動(dong)關(guan)閉(bi)(bi)件向下(xia)移動(dong)，關(guan)閉(bi)(bi)閥(fa)門。 ATOS電磁閥特點：流體(ti)壓力范(fan)圍(wei)上限較高，可(ke)任意安(an)裝（需定制）但必須滿足流體(ti)壓差條(tiao)件。 2、電磁閥(fa)(fa)從閥(fa)(fa)結(jie)(jie)構(gou)(gou)(gou)和材(cai)料上(shang)的不同與原理上(shang)的區別(bie)，分(fen)為六(liu)個分(fen)支小類：直動(dong)膜(mo)片結(jie)(jie)構(gou)(gou)(gou)、分(fen)步直動(dong)膜(mo)片結(jie)(jie)構(gou)(gou)(gou)、先導(dao)膜(mo)片結(jie)(jie)構(gou)(gou)(gou)、直動(dong)活(huo)塞(sai)結(jie)(jie)構(gou)(gou)(gou)、分(fen)步直動(dong)活(huo)塞(sai)結(jie)(jie)構(gou)(gou)(gou)、先導(dao)活(huo)塞(sai)結(jie)(jie)構(gou)(gou)(gou)。 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)按照功能分類：水(shui)用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氨用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、氣體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液(ye)體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、脈(mo)沖(chong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、液(ye)壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa) 常(chang)開電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、油用電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、高(gao)壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)、防爆(bao)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)等。 意大利(li)ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
