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(dian)磁(ci)閥： ATOS電(dian)(dian)磁閥原理(li)：通電(dian)(dian)時(shi)，電(dian)(dian)磁線圈(quan)產生電(dian)(dian)磁力(li)把(ba)關(guan)(guan)閉件(jian)從閥座上提起，閥門打開；斷電(dian)(dian)時(shi)，電(dian)(dian)磁力(li)消(xiao)失，彈(dan)簧把(ba)關(guan)(guan)閉件(jian)壓在閥座上，閥門關(guan)(guan)閉。 ATOS電磁閥特點：在(zai)真(zhen)空(kong)、負壓(ya)、零(ling)壓(ya)時(shi)能正常工作，但通徑一般(ban)不超過25mm。 2）分步直動式電磁(ci)閥： ATOS電磁(ci)閥(fa)(fa)原理：它是一種直動(dong)和先導(dao)式相結合的原理，當入口與出口沒(mei)有壓(ya)(ya)(ya)差時，通(tong)電后(hou)，電磁(ci)力(li)(li)直接把(ba)先導(dao)小閥(fa)(fa)和主(zhu)閥(fa)(fa)關閉(bi)件(jian)依(yi)次向上(shang)(shang)提起，閥(fa)(fa)門打開。當入口與出口達到啟動(dong)壓(ya)(ya)(ya)差時，通(tong)電后(hou)，電磁(ci)力(li)(li)先導(dao)小閥(fa)(fa)，主(zhu)閥(fa)(fa)下(xia)(xia)腔壓(ya)(ya)(ya)力(li)(li)上(shang)(shang)升，上(shang)(shang)腔壓(ya)(ya)(ya)力(li)(li)下(xia)(xia)降，從而利用壓(ya)(ya)(ya)差把(ba)主(zhu)閥(fa)(fa)向上(shang)(shang)推開；斷電時，先導(dao)閥(fa)(fa)利用彈簧力(li)(li)或介質壓(ya)(ya)(ya)力(li)(li)推動(dong)關閉(bi)件(jian)，向下(xia)(xia)移動(dong)，使(shi)閥(fa)(fa)門關閉(bi)。 ATOS電磁(ci)閥(fa)特點：在零壓(ya)差或真空、高壓(ya)時亦能可(ke)*動作，但(dan)功率較大，要求必須水平安裝(zhuang)。 3）先導式電磁閥： ATOS電磁閥原理：通電時，電磁力把先(xian)導(dao)孔打開，上腔室壓力迅(xun)速下降，在關(guan)(guan) 閉件周(zhou)圍形成上低下高(gao)的(de)(de)壓差，流(liu)體(ti)壓力推動(dong)(dong)關(guan)(guan)閉件向上移動(dong)(dong)，閥門(men)打開；斷(duan)電時，彈簧(huang)力把先(xian)導(dao)孔關(guan)(guan)閉，入(ru)口壓力通過旁通孔迅(xun)速腔室在關(guan)(guan)閥件周(zhou)圍形成下低上高(gao)的(de)(de)壓差，流(liu)體(ti)壓力推動(dong)(dong)關(guan)(guan)閉件向下移動(dong)(dong)，關(guan)(guan)閉閥門(men)。 ATOS電磁閥特點(dian)：流(liu)體(ti)壓力范圍上限較高，可任意安(an)裝(zhuang)（需定制）但必須滿足流(liu)體(ti)壓差(cha)條件(jian)。 2、電磁閥從閥結構(gou)(gou)和材(cai)料上(shang)的不同與(yu)原(yuan)理(li)上(shang)的區別，分為六個分支小類：直(zhi)動膜(mo)片(pian)結構(gou)(gou)、分步直(zhi)動膜(mo)片(pian)結構(gou)(gou)、先導膜(mo)片(pian)結構(gou)(gou)、直(zhi)動活塞(sai)結構(gou)(gou)、分步直(zhi)動活塞(sai)結構(gou)(gou)、先導活塞(sai)結構(gou)(gou)。 3、電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)按照功能分類：水用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、蒸汽電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、制冷電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、低(di)溫電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、燃氣電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、消防(fang)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、氨用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、氣體電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、液體電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、微(wei)型電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、脈(mo)沖電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、液壓電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa) 常(chang)開電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、油(you)用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、直流(liu)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、高壓電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)、防(fang)爆電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)等(deng)。 意大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
