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(li)上分為三大(da)類： 1）ATOS直動式電磁閥： ATOS電(dian)(dian)(dian)磁(ci)閥原理：通電(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)磁(ci)線圈(quan)產生電(dian)(dian)(dian)磁(ci)力(li)把關(guan)(guan)閉(bi)(bi)件(jian)從閥座上提起(qi)，閥門打開；斷(duan)電(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)磁(ci)力(li)消(xiao)失，彈簧(huang)把關(guan)(guan)閉(bi)(bi)件(jian)壓在閥座上，閥門關(guan)(guan)閉(bi)(bi)。 ATOS電磁閥特點：在真空、負壓(ya)(ya)、零(ling)壓(ya)(ya)時能正(zheng)常工作(zuo)，但通徑(jing)一般不(bu)超(chao)過25mm。 2）分(fen)步直動式電磁閥： ATOS電(dian)磁閥原(yuan)理(li)：它是一種直動(dong)和先導(dao)式相結(jie)合的原(yuan)理(li)，當入口(kou)(kou)(kou)與(yu)出口(kou)(kou)(kou)沒(mei)有壓(ya)(ya)差時(shi)，通電(dian)后，電(dian)磁力(li)直接把(ba)先導(dao)小(xiao)閥和主(zhu)閥關閉件依(yi)次(ci)向(xiang)上(shang)(shang)提起(qi)，閥門打開(kai)。當入口(kou)(kou)(kou)與(yu)出口(kou)(kou)(kou)達到(dao)啟動(dong)壓(ya)(ya)差時(shi)，通電(dian)后，電(dian)磁力(li)先導(dao)小(xiao)閥，主(zhu)閥下腔(qiang)壓(ya)(ya)力(li)上(shang)(shang)升，上(shang)(shang)腔(qiang)壓(ya)(ya)力(li)下降，從(cong)而利(li)用壓(ya)(ya)差把(ba)主(zhu)閥向(xiang)上(shang)(shang)推(tui)開(kai)；斷(duan)電(dian)時(shi)，先導(dao)閥利(li)用彈(dan)簧力(li)或介(jie)質壓(ya)(ya)力(li)推(tui)動(dong)關閉件，向(xiang)下移動(dong)，使閥門關閉。 ATOS電磁閥特點(dian)：在零(ling)壓差(cha)或真空、高壓時(shi)亦能可(ke)*動作，但功率(lv)較大，要求必須水平(ping)安裝。 3）先導式電磁(ci)閥(fa)： ATOS電(dian)(dian)磁閥(fa)原(yuan)理：通電(dian)(dian)時(shi)，電(dian)(dian)磁力(li)(li)(li)把先導(dao)孔(kong)打開，上腔(qiang)室(shi)(shi)壓(ya)(ya)力(li)(li)(li)迅速下(xia)(xia)降，在關(guan)(guan) 閉件周(zhou)圍形(xing)成上低下(xia)(xia)高的(de)壓(ya)(ya)差(cha)，流(liu)體壓(ya)(ya)力(li)(li)(li)推動(dong)關(guan)(guan)閉件向上移(yi)動(dong)，閥(fa)門打開；斷(duan)電(dian)(dian)時(shi)，彈簧力(li)(li)(li)把先導(dao)孔(kong)關(guan)(guan)閉，入口壓(ya)(ya)力(li)(li)(li)通過旁通孔(kong)迅速腔(qiang)室(shi)(shi)在關(guan)(guan)閥(fa)件周(zhou)圍形(xing)成下(xia)(xia)低上高的(de)壓(ya)(ya)差(cha)，流(liu)體壓(ya)(ya)力(li)(li)(li)推動(dong)關(guan)(guan)閉件向下(xia)(xia)移(yi)動(dong)，關(guan)(guan)閉閥(fa)門。 ATOS電磁閥特點(dian)：流體(ti)壓力范圍上(shang)限較高，可任意安裝（需定制）但(dan)必須(xu)滿(man)足流體(ti)壓差條件。 2、電磁閥從(cong)閥結(jie)(jie)構和材料上(shang)的不(bu)同與原理上(shang)的區別，分為六個分支小(xiao)類(lei)：直動(dong)(dong)膜片結(jie)(jie)構、分步(bu)直動(dong)(dong)膜片結(jie)(jie)構、先導膜片結(jie)(jie)構、直動(dong)(dong)活(huo)塞結(jie)(jie)構、分步(bu)直動(dong)(dong)活(huo)塞結(jie)(jie)構、先導活(huo)塞結(jie)(jie)構。 3、電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)按照功能分類：水(shui)用電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、蒸(zheng)汽電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氨用電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氣體電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液體電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液壓(ya)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、油用電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、高壓(ya)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、防爆電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)等。 意大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
