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(yuan)理(li)上分為(wei)三大(da)類： 1）ATOS直動式電磁閥(fa)： ATOS電(dian)磁(ci)閥原理：通電(dian)時，電(dian)磁(ci)線圈產(chan)生電(dian)磁(ci)力把關(guan)閉件(jian)從閥座(zuo)上(shang)提起，閥門(men)打開；斷電(dian)時，電(dian)磁(ci)力消失，彈簧把關(guan)閉件(jian)壓在閥座(zuo)上(shang)，閥門(men)關(guan)閉。 ATOS電磁閥特點：在(zai)真空、負壓、零壓時(shi)能(neng)正(zheng)常(chang)工作，但通徑一般不超(chao)過25mm。 2）分步直動式電磁閥： ATOS電(dian)(dian)磁閥(fa)原(yuan)理：它是一種直(zhi)動(dong)和(he)先(xian)導(dao)式(shi)相(xiang)結(jie)合的(de)原(yuan)理，當入口(kou)(kou)與(yu)出(chu)口(kou)(kou)沒有(you)壓(ya)差時(shi)，通(tong)(tong)電(dian)(dian)后(hou)，電(dian)(dian)磁力(li)(li)直(zhi)接把先(xian)導(dao)小(xiao)閥(fa)和(he)主(zhu)閥(fa)關閉件(jian)依次向(xiang)上提起，閥(fa)門打開。當入口(kou)(kou)與(yu)出(chu)口(kou)(kou)達到(dao)啟動(dong)壓(ya)差時(shi)，通(tong)(tong)電(dian)(dian)后(hou)，電(dian)(dian)磁力(li)(li)先(xian)導(dao)小(xiao)閥(fa)，主(zhu)閥(fa)下腔(qiang)壓(ya)力(li)(li)上升，上腔(qiang)壓(ya)力(li)(li)下降，從而利用(yong)壓(ya)差把主(zhu)閥(fa)向(xiang)上推(tui)開；斷電(dian)(dian)時(shi)，先(xian)導(dao)閥(fa)利用(yong)彈簧力(li)(li)或介質壓(ya)力(li)(li)推(tui)動(dong)關閉件(jian)，向(xiang)下移動(dong)，使閥(fa)門關閉。 ATOS電磁閥特點：在零壓(ya)差或真空、高壓(ya)時亦能可*動作，但功(gong)率較大，要求(qiu)必(bi)須水(shui)平安裝。 3）先(xian)導式電磁閥： ATOS電(dian)磁閥原理(li)：通(tong)電(dian)時(shi)，電(dian)磁力(li)(li)把先(xian)導孔打(da)開，上腔室壓(ya)(ya)力(li)(li)迅(xun)速下降(jiang)，在關 閉(bi)件(jian)周(zhou)圍形成(cheng)(cheng)上低下高的(de)壓(ya)(ya)差，流(liu)體壓(ya)(ya)力(li)(li)推動(dong)關閉(bi)件(jian)向上移動(dong)，閥門(men)打(da)開；斷電(dian)時(shi)，彈簧力(li)(li)把先(xian)導孔關閉(bi)，入口(kou)壓(ya)(ya)力(li)(li)通(tong)過旁通(tong)孔迅(xun)速腔室在關閥件(jian)周(zhou)圍形成(cheng)(cheng)下低上高的(de)壓(ya)(ya)差，流(liu)體壓(ya)(ya)力(li)(li)推動(dong)關閉(bi)件(jian)向下移動(dong)，關閉(bi)閥門(men)。 ATOS電磁閥特點：流體壓(ya)力范圍上限較高，可任意安裝（需定制(zhi)）但必(bi)須滿(man)足流體壓(ya)差(cha)條(tiao)件。 2、電磁閥從閥結(jie)構(gou)(gou)(gou)和材料上的不同(tong)與(yu)原理上的區別，分為六個分支小類：直動膜(mo)片(pian)結(jie)構(gou)(gou)(gou)、分步直動膜(mo)片(pian)結(jie)構(gou)(gou)(gou)、先(xian)導膜(mo)片(pian)結(jie)構(gou)(gou)(gou)、直動活(huo)塞結(jie)構(gou)(gou)(gou)、分步直動活(huo)塞結(jie)構(gou)(gou)(gou)、先(xian)導活(huo)塞結(jie)構(gou)(gou)(gou)。 3、電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)按照功能分類：水(shui)用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、制(zhi)冷電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、消防(fang)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、氣體電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、液體電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、微型(xing)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、液壓電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、油用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、直流電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、高壓電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)、防(fang)爆電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)等。 意大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
