意大利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電磁閥從原理上分為三大類： 1）ATOS直動式電磁閥： ATOS電磁閥(fa)(fa)原理(li)：通電時，電磁線圈產生電磁力把關閉件(jian)從閥(fa)(fa)座上(shang)提起，閥(fa)(fa)門(men)打開；斷電時，電磁力消失，彈簧把關閉件(jian)壓(ya)在閥(fa)(fa)座上(shang)，閥(fa)(fa)門(men)關閉。 ATOS電磁閥特點：在真(zhen)空、負壓(ya)(ya)、零壓(ya)(ya)時能正常(chang)工作(zuo)，但通徑一般(ban)不超(chao)過25mm。 2）分步直動式(shi)電磁閥： ATOS電(dian)(dian)磁閥(fa)(fa)(fa)原理：它(ta)是一種直(zhi)動和(he)先導(dao)式(shi)相結合的原理，當(dang)入口與(yu)出(chu)口沒有(you)壓(ya)差(cha)時，通電(dian)(dian)后(hou)，電(dian)(dian)磁力直(zhi)接把(ba)先導(dao)小閥(fa)(fa)(fa)和(he)主(zhu)閥(fa)(fa)(fa)關閉件依次向上提起，閥(fa)(fa)(fa)門打(da)開。當(dang)入口與(yu)出(chu)口達到(dao)啟動壓(ya)差(cha)時，通電(dian)(dian)后(hou)，電(dian)(dian)磁力先導(dao)小閥(fa)(fa)(fa)，主(zhu)閥(fa)(fa)(fa)下腔壓(ya)力上升(sheng)，上腔壓(ya)力下降，從而利(li)用壓(ya)差(cha)把(ba)主(zhu)閥(fa)(fa)(fa)向上推(tui)開；斷電(dian)(dian)時，先導(dao)閥(fa)(fa)(fa)利(li)用彈簧力或介質壓(ya)力推(tui)動關閉件，向下移動，使閥(fa)(fa)(fa)門關閉。 ATOS電磁閥特點：在零(ling)壓差或真空、高壓時亦能(neng)可*動作，但(dan)功率較大(da)，要求(qiu)必須水平安裝。 3）先(xian)導式(shi)電磁(ci)閥： ATOS電(dian)磁閥原(yuan)理(li)：通(tong)電(dian)時，電(dian)磁力(li)(li)把先導孔打開，上腔室壓力(li)(li)迅(xun)速下降，在關 閉件周圍形(xing)成上低下高的壓差，流(liu)體壓力(li)(li)推動(dong)關閉件向上移動(dong)，閥門打開；斷電(dian)時，彈簧力(li)(li)把先導孔關閉，入(ru)口(kou)壓力(li)(li)通(tong)過(guo)旁通(tong)孔迅(xun)速腔室在關閥件周圍形(xing)成下低上高的壓差，流(liu)體壓力(li)(li)推動(dong)關閉件向下移動(dong)，關閉閥門。 ATOS電(dian)磁閥特點(dian)：流體(ti)壓力范圍上限較高，可任意安裝（需定(ding)制）但必(bi)須滿足(zu)流體(ti)壓差條件。 2、電磁閥(fa)從閥(fa)結構(gou)和材料(liao)上(shang)的(de)不同與原(yuan)理(li)上(shang)的(de)區別，分為(wei)六個分支小類：直動(dong)(dong)膜片(pian)(pian)結構(gou)、分步直動(dong)(dong)膜片(pian)(pian)結構(gou)、先導(dao)膜片(pian)(pian)結構(gou)、直動(dong)(dong)活塞(sai)結構(gou)、分步直動(dong)(dong)活塞(sai)結構(gou)、先導(dao)活塞(sai)結構(gou)。 3、電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)按照功能(neng)分(fen)類：水用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、蒸(zheng)汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、燃(ran)氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、消防(fang)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、氨用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、氣體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、微型(xing)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、油用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、防(fang)爆電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)等。 意大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
