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(dian)(dian)磁(ci)閥(fa)原理：通電(dian)(dian)時(shi)，電(dian)(dian)磁(ci)線圈產生電(dian)(dian)磁(ci)力(li)把關閉(bi)件(jian)從閥(fa)座上提起，閥(fa)門打開；斷(duan)電(dian)(dian)時(shi)，電(dian)(dian)磁(ci)力(li)消失，彈(dan)簧把關閉(bi)件(jian)壓在閥(fa)座上，閥(fa)門關閉(bi)。 ATOS電(dian)磁閥(fa)特點：在真空、負壓、零壓時能正常工作，但通徑一般不超過25mm。 2）分步直動式電磁(ci)閥(fa)： ATOS電(dian)(dian)磁閥原(yuan)理(li)：它(ta)是一種直(zhi)動(dong)和(he)先(xian)導式相結合的原(yuan)理(li)，當入口與(yu)出(chu)口沒有(you)壓(ya)差時，通電(dian)(dian)后(hou)，電(dian)(dian)磁力(li)直(zhi)接把先(xian)導小(xiao)閥和(he)主(zhu)閥關閉件依次向(xiang)上(shang)提起，閥門打開。當入口與(yu)出(chu)口達到啟(qi)動(dong)壓(ya)差時，通電(dian)(dian)后(hou)，電(dian)(dian)磁力(li)先(xian)導小(xiao)閥，主(zhu)閥下(xia)(xia)腔(qiang)壓(ya)力(li)上(shang)升(sheng)，上(shang)腔(qiang)壓(ya)力(li)下(xia)(xia)降，從而利用壓(ya)差把主(zhu)閥向(xiang)上(shang)推開；斷電(dian)(dian)時，先(xian)導閥利用彈簧力(li)或介質(zhi)壓(ya)力(li)推動(dong)關閉件，向(xiang)下(xia)(xia)移動(dong)，使閥門關閉。 ATOS電磁閥特(te)點(dian)：在零(ling)壓差或真空、高壓時(shi)亦能可*動作，但功率較大，要求必須水(shui)平安裝。 3）先導(dao)式電磁閥： ATOS電(dian)磁(ci)閥(fa)原理(li)：通(tong)(tong)電(dian)時，電(dian)磁(ci)力(li)(li)(li)把先導孔(kong)打開(kai)，上(shang)腔室(shi)壓(ya)力(li)(li)(li)迅速下降，在關(guan) 閉件(jian)周圍(wei)形成上(shang)低下高的壓(ya)差，流體壓(ya)力(li)(li)(li)推(tui)動(dong)(dong)關(guan)閉件(jian)向(xiang)上(shang)移動(dong)(dong)，閥(fa)門(men)打開(kai)；斷電(dian)時，彈簧力(li)(li)(li)把先導孔(kong)關(guan)閉，入(ru)口壓(ya)力(li)(li)(li)通(tong)(tong)過旁通(tong)(tong)孔(kong)迅速腔室(shi)在關(guan)閥(fa)件(jian)周圍(wei)形成下低上(shang)高的壓(ya)差，流體壓(ya)力(li)(li)(li)推(tui)動(dong)(dong)關(guan)閉件(jian)向(xiang)下移動(dong)(dong)，關(guan)閉閥(fa)門(men)。 ATOS電磁閥特點：流體壓力范圍(wei)上限較(jiao)高，可(ke)任意安裝（需定制）但必(bi)須滿(man)足流體壓差條件。 2、電磁(ci)閥從閥結(jie)(jie)構和(he)材料上的不同(tong)與原理上的區別，分為六個分支小類(lei)：直(zhi)動膜片(pian)結(jie)(jie)構、分步直(zhi)動膜片(pian)結(jie)(jie)構、先導膜片(pian)結(jie)(jie)構、直(zhi)動活(huo)塞結(jie)(jie)構、分步直(zhi)動活(huo)塞結(jie)(jie)構、先導活(huo)塞結(jie)(jie)構。 3、電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)按照功(gong)能(neng)分類：水用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、制(zhi)冷電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氣體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)壓電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa) 常開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、油用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、高壓電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、防爆電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)等。 意大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
