意大利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)閥從原理上分為三大類： 1）ATOS直動式電磁閥： ATOS電(dian)磁(ci)(ci)閥(fa)原理：通電(dian)時(shi)，電(dian)磁(ci)(ci)線圈產生(sheng)電(dian)磁(ci)(ci)力把(ba)關(guan)閉(bi)件(jian)從(cong)閥(fa)座上提(ti)起，閥(fa)門打開；斷電(dian)時(shi)，電(dian)磁(ci)(ci)力消失(shi)，彈(dan)簧把(ba)關(guan)閉(bi)件(jian)壓(ya)在閥(fa)座上，閥(fa)門關(guan)閉(bi)。 ; ATOS電磁閥特點：在真空、負壓(ya)、零壓(ya)時(shi)能正常工作，但通徑一般(ban)不超過25mm。 2）分步直(zhi)動式電(dian)磁閥(fa)： ATOS電(dian)(dian)磁(ci)閥(fa)原(yuan)理：它是一種直動和先(xian)導式(shi)相結合的原(yuan)理，當入口(kou)與(yu)出口(kou)沒(mei)有壓(ya)差時，通(tong)電(dian)(dian)后，電(dian)(dian)磁(ci)力(li)直接把(ba)先(xian)導小閥(fa)和主(zhu)(zhu)閥(fa)關閉(bi)件依次(ci)向上(shang)(shang)提起(qi)，閥(fa)門打(da)開。當入口(kou)與(yu)出口(kou)達到啟動壓(ya)差時，通(tong)電(dian)(dian)后，電(dian)(dian)磁(ci)力(li)先(xian)導小閥(fa)，主(zhu)(zhu)閥(fa)下腔壓(ya)力(li)上(shang)(shang)升(sheng)，上(shang)(shang)腔壓(ya)力(li)下降，從(cong)而利(li)用壓(ya)差把(ba)主(zhu)(zhu)閥(fa)向上(shang)(shang)推開；斷電(dian)(dian)時，先(xian)導閥(fa)利(li)用彈簧力(li)或(huo)介質(zhi)壓(ya)力(li)推動關閉(bi)件，向下移(yi)動，使閥(fa)門關閉(bi)。 ATOS電磁閥特(te)點：在零壓(ya)差或(huo)真(zhen)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。 3）先導式電磁(ci)閥： ATOS電(dian)磁閥原理：通(tong)(tong)電(dian)時，電(dian)磁力(li)把(ba)先導孔(kong)打開，上腔室壓(ya)(ya)力(li)迅(xun)速下降，在關 閉(bi)件(jian)周圍(wei)形(xing)成上低(di)下高的壓(ya)(ya)差，流體(ti)壓(ya)(ya)力(li)推動關閉(bi)件(jian)向上移(yi)動，閥門打開；斷電(dian)時，彈(dan)簧力(li)把(ba)先導孔(kong)關閉(bi)，入(ru)口壓(ya)(ya)力(li)通(tong)(tong)過(guo)旁通(tong)(tong)孔(kong)迅(xun)速腔室在關閥件(jian)周圍(wei)形(xing)成下低(di)上高的壓(ya)(ya)差，流體(ti)壓(ya)(ya)力(li)推動關閉(bi)件(jian)向下移(yi)動，關閉(bi)閥門。 ATOS電磁(ci)閥(fa)特點(dian)：流(liu)體壓力范圍(wei)上限較高(gao)，可任意安(an)裝（需定制）但必須滿足流(liu)體壓差(cha)條件。 2、電磁閥從閥結(jie)(jie)(jie)(jie)構和材料(liao)上(shang)的不同(tong)與原理上(shang)的區別(bie)，分(fen)為六個分(fen)支小類：直動(dong)膜片(pian)結(jie)(jie)(jie)(jie)構、分(fen)步直動(dong)膜片(pian)結(jie)(jie)(jie)(jie)構、先(xian)導膜片(pian)結(jie)(jie)(jie)(jie)構、直動(dong)活塞結(jie)(jie)(jie)(jie)構、分(fen)步直動(dong)活塞結(jie)(jie)(jie)(jie)構、先(xian)導活塞結(jie)(jie)(jie)(jie)構。 3、電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)按照功能分類(lei)：水(shui)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、蒸(zheng)汽電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、制冷(leng)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、低溫電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、燃(ran)氣電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、消防電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、氨用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、氣體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、液(ye)(ye)體電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、微型電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、液(ye)(ye)壓電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa) 常開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、油(you)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)、防爆(bao)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)等。 意(yi)大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
