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(fa)從原理上分為三大類(lei)： 1）ATOS直動式電磁閥： ATOS電(dian)磁閥原理(li)：通電(dian)時(shi)，電(dian)磁線圈產生電(dian)磁力把(ba)關(guan)閉(bi)件從閥座上提起，閥門打開；斷電(dian)時(shi)，電(dian)磁力消失，彈(dan)簧把(ba)關(guan)閉(bi)件壓在(zai)閥座上，閥門關(guan)閉(bi)。 ATOS電磁閥特點：在真空、負壓、零壓時能(neng)正(zheng)常工作，但通徑一(yi)般(ban)不(bu)超過(guo)25mm。 2）分步直動式電(dian)磁閥： ATOS電(dian)(dian)磁(ci)閥(fa)原理(li)(li)：它是一種(zhong)直動(dong)和先導(dao)式相(xiang)結合的原理(li)(li)，當入口與出(chu)口沒有(you)壓(ya)(ya)差(cha)時，通(tong)電(dian)(dian)后，電(dian)(dian)磁(ci)力(li)直接把先導(dao)小(xiao)閥(fa)和主閥(fa)關閉件(jian)依次向(xiang)上提起(qi)，閥(fa)門打開。當入口與出(chu)口達到啟(qi)動(dong)壓(ya)(ya)差(cha)時，通(tong)電(dian)(dian)后，電(dian)(dian)磁(ci)力(li)先導(dao)小(xiao)閥(fa)，主閥(fa)下(xia)腔壓(ya)(ya)力(li)上升(sheng)，上腔壓(ya)(ya)力(li)下(xia)降(jiang)，從而利用(yong)壓(ya)(ya)差(cha)把主閥(fa)向(xiang)上推開；斷電(dian)(dian)時，先導(dao)閥(fa)利用(yong)彈簧力(li)或(huo)介質(zhi)壓(ya)(ya)力(li)推動(dong)關閉件(jian)，向(xiang)下(xia)移動(dong)，使閥(fa)門關閉。 ATOS電磁閥特(te)點(dian)：在零壓差或真空、高壓時亦能可(ke)*動(dong)作，但功率較大，要求必須水(shui)平安裝。 3）先導式(shi)電磁(ci)閥： ATOS電(dian)(dian)磁(ci)閥原理：通電(dian)(dian)時，電(dian)(dian)磁(ci)力(li)把先導孔(kong)打(da)開，上(shang)腔(qiang)室壓(ya)(ya)力(li)迅(xun)速(su)下(xia)(xia)降，在(zai)(zai)關 閉(bi)件(jian)(jian)周(zhou)圍(wei)形(xing)成上(shang)低下(xia)(xia)高(gao)(gao)的壓(ya)(ya)差(cha)，流體壓(ya)(ya)力(li)推(tui)動(dong)關閉(bi)件(jian)(jian)向上(shang)移(yi)動(dong)，閥門打(da)開；斷電(dian)(dian)時，彈(dan)簧力(li)把先導孔(kong)關閉(bi)，入口壓(ya)(ya)力(li)通過旁通孔(kong)迅(xun)速(su)腔(qiang)室在(zai)(zai)關閥件(jian)(jian)周(zhou)圍(wei)形(xing)成下(xia)(xia)低上(shang)高(gao)(gao)的壓(ya)(ya)差(cha)，流體壓(ya)(ya)力(li)推(tui)動(dong)關閉(bi)件(jian)(jian)向下(xia)(xia)移(yi)動(dong)，關閉(bi)閥門。 ATOS電(dian)磁閥特(te)點：流(liu)體(ti)壓(ya)力范圍上限(xian)較高，可任意安(an)裝（需定制）但(dan)必須滿足流(liu)體(ti)壓(ya)差(cha)條件(jian)。 2、電磁閥從閥結構和材料(liao)上的不同與原(yuan)理(li)上的區(qu)別(bie)，分為六(liu)個分支(zhi)小類：直動(dong)(dong)膜片結構、分步(bu)直動(dong)(dong)膜片結構、先導膜片結構、直動(dong)(dong)活(huo)塞結構、分步(bu)直動(dong)(dong)活(huo)塞結構、先導活(huo)塞結構。 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)按照功(gong)能分(fen)類(lei)：水(shui)用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氣體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液壓(ya)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、油(you)用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、高(gao)壓(ya)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、防爆電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)等(deng)。 意大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
