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(cong)原理上分為(wei)三大類(lei)： 1）ATOS直動(dong)式電磁(ci)閥： ATOS電(dian)磁閥(fa)原理：通電(dian)時(shi)，電(dian)磁線圈產生電(dian)磁力(li)把關閉(bi)件(jian)從閥(fa)座(zuo)上提起，閥(fa)門打開；斷電(dian)時(shi)，電(dian)磁力(li)消失(shi)，彈簧(huang)把關閉(bi)件(jian)壓在(zai)閥(fa)座(zuo)上，閥(fa)門關閉(bi)。 ATOS電磁閥特點：在真空、負壓、零壓時能(neng)正(zheng)常(chang)工(gong)作，但通(tong)徑一般不(bu)超過(guo)25mm。 2）分步(bu)直(zhi)動式電磁閥： ATOS電(dian)(dian)(dian)磁(ci)閥(fa)(fa)原理：它是一種直動(dong)和先(xian)(xian)導式相結合(he)的原理，當入口(kou)(kou)(kou)與出口(kou)(kou)(kou)沒有壓(ya)差時(shi)，通電(dian)(dian)(dian)后，電(dian)(dian)(dian)磁(ci)力直接把(ba)先(xian)(xian)導小(xiao)閥(fa)(fa)和主(zhu)閥(fa)(fa)關閉(bi)件依(yi)次向上提起，閥(fa)(fa)門(men)(men)打開(kai)。當入口(kou)(kou)(kou)與出口(kou)(kou)(kou)達(da)到啟動(dong)壓(ya)差時(shi)，通電(dian)(dian)(dian)后，電(dian)(dian)(dian)磁(ci)力先(xian)(xian)導小(xiao)閥(fa)(fa)，主(zhu)閥(fa)(fa)下(xia)腔壓(ya)力上升，上腔壓(ya)力下(xia)降，從而利用壓(ya)差把(ba)主(zhu)閥(fa)(fa)向上推(tui)開(kai)；斷電(dian)(dian)(dian)時(shi)，先(xian)(xian)導閥(fa)(fa)利用彈簧(huang)力或介質壓(ya)力推(tui)動(dong)關閉(bi)件，向下(xia)移動(dong)，使閥(fa)(fa)門(men)(men)關閉(bi)。 ATOS電磁閥(fa)特(te)點：在零壓差或(huo)真(zhen)空(kong)、高壓時亦能可*動作，但功率較大，要求必須水平安(an)裝。 3）先導(dao)式電磁閥： ATOS電磁閥(fa)原理：通(tong)電時，電磁力(li)把先導孔打開，上(shang)腔室(shi)壓(ya)力(li)迅速下降，在關(guan) 閉(bi)件(jian)周(zhou)圍形成(cheng)上(shang)低(di)下高的壓(ya)差(cha)(cha)，流體(ti)壓(ya)力(li)推動關(guan)閉(bi)件(jian)向(xiang)上(shang)移(yi)動，閥(fa)門打開；斷(duan)電時，彈(dan)簧力(li)把先導孔關(guan)閉(bi)，入口(kou)壓(ya)力(li)通(tong)過旁通(tong)孔迅速腔室(shi)在關(guan)閥(fa)件(jian)周(zhou)圍形成(cheng)下低(di)上(shang)高的壓(ya)差(cha)(cha)，流體(ti)壓(ya)力(li)推動關(guan)閉(bi)件(jian)向(xiang)下移(yi)動，關(guan)閉(bi)閥(fa)門。 ATOS電(dian)磁閥特點：流(liu)體(ti)(ti)壓(ya)力范圍上限(xian)較高，可任意安裝（需定制）但必須滿足流(liu)體(ti)(ti)壓(ya)差條件。 2、電(dian)磁閥從閥結(jie)構(gou)(gou)(gou)和材料(liao)上的不同與原理上的區別，分(fen)為六個分(fen)支小類：直(zhi)動膜(mo)片(pian)結(jie)構(gou)(gou)(gou)、分(fen)步(bu)直(zhi)動膜(mo)片(pian)結(jie)構(gou)(gou)(gou)、先導膜(mo)片(pian)結(jie)構(gou)(gou)(gou)、直(zhi)動活(huo)塞(sai)結(jie)構(gou)(gou)(gou)、分(fen)步(bu)直(zhi)動活(huo)塞(sai)結(jie)構(gou)(gou)(gou)、先導活(huo)塞(sai)結(jie)構(gou)(gou)(gou)。 3、電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)按照功(gong)能分類(lei)：水用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、制冷電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、燃氣(qi)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、消防電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、氨(an)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、氣(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、液體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、微型電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、脈沖(chong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、液壓電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa) 常開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、油(you)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、直流電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、高壓電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)、防爆電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)等(deng)。 意(yi)大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
