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電磁閥從原理上分為(wei)三大類： 1）ATOS直動式電磁閥： ATOS電(dian)磁(ci)(ci)閥(fa)原理(li)：通電(dian)時(shi)，電(dian)磁(ci)(ci)線(xian)圈產(chan)生(sheng)電(dian)磁(ci)(ci)力把關閉件從(cong)閥(fa)座上提(ti)起，閥(fa)門打開(kai)；斷電(dian)時(shi)，電(dian)磁(ci)(ci)力消失，彈簧把關閉件壓在閥(fa)座上，閥(fa)門關閉。 ATOS電(dian)磁閥特(te)點(dian)：在真空、負壓、零(ling)壓時能正常(chang)工作，但通徑一般不超過25mm。 2）分步直動式(shi)電(dian)磁閥： ATOS電(dian)(dian)(dian)磁(ci)閥原(yuan)理(li)：它是一種(zhong)直動(dong)(dong)和先(xian)導(dao)式相結合的(de)原(yuan)理(li)，當(dang)入口(kou)與出口(kou)沒有壓(ya)差(cha)時(shi)，通電(dian)(dian)(dian)后(hou)，電(dian)(dian)(dian)磁(ci)力(li)直接把先(xian)導(dao)小(xiao)閥和主(zhu)閥關閉(bi)件依次向(xiang)上提(ti)起，閥門打開。當(dang)入口(kou)與出口(kou)達到啟動(dong)(dong)壓(ya)差(cha)時(shi)，通電(dian)(dian)(dian)后(hou)，電(dian)(dian)(dian)磁(ci)力(li)先(xian)導(dao)小(xiao)閥，主(zhu)閥下腔(qiang)壓(ya)力(li)上升(sheng)，上腔(qiang)壓(ya)力(li)下降，從(cong)而利用(yong)壓(ya)差(cha)把主(zhu)閥向(xiang)上推開；斷電(dian)(dian)(dian)時(shi)，先(xian)導(dao)閥利用(yong)彈(dan)簧(huang)力(li)或介質壓(ya)力(li)推動(dong)(dong)關閉(bi)件，向(xiang)下移(yi)動(dong)(dong)，使閥門關閉(bi)。 ATOS電(dian)磁閥特點(dian)：在零壓(ya)差或真空、高壓(ya)時亦能可*動作(zuo)，但功率較大，要求(qiu)必(bi)須水平安裝。 3）先導式電磁(ci)閥： ATOS電磁閥原理：通電時，電磁力(li)把先(xian)導孔(kong)(kong)(kong)打開，上腔室壓(ya)力(li)迅速下(xia)降，在關(guan) 閉件周圍(wei)形(xing)成上低下(xia)高的(de)壓(ya)差(cha)，流體(ti)壓(ya)力(li)推(tui)動(dong)關(guan)閉件向(xiang)上移動(dong)，閥門(men)打開；斷電時，彈簧力(li)把先(xian)導孔(kong)(kong)(kong)關(guan)閉，入口(kou)壓(ya)力(li)通過旁(pang)通孔(kong)(kong)(kong)迅速腔室在關(guan)閥件周圍(wei)形(xing)成下(xia)低上高的(de)壓(ya)差(cha)，流體(ti)壓(ya)力(li)推(tui)動(dong)關(guan)閉件向(xiang)下(xia)移動(dong)，關(guan)閉閥門(men)。 ATOS電磁閥特(te)點(dian)：流體(ti)壓(ya)力范(fan)圍上限較高，可任(ren)意安(an)裝（需定制(zhi)）但必須(xu)滿足流體(ti)壓(ya)差條件(jian)。 2、電磁閥(fa)(fa)從(cong)閥(fa)(fa)結(jie)構(gou)(gou)和材料上的不同(tong)與(yu)原理(li)上的區別(bie)，分(fen)為六(liu)個(ge)分(fen)支小類：直(zhi)(zhi)動(dong)膜(mo)片結(jie)構(gou)(gou)、分(fen)步(bu)直(zhi)(zhi)動(dong)膜(mo)片結(jie)構(gou)(gou)、先(xian)導膜(mo)片結(jie)構(gou)(gou)、直(zhi)(zhi)動(dong)活(huo)塞結(jie)構(gou)(gou)、分(fen)步(bu)直(zhi)(zhi)動(dong)活(huo)塞結(jie)構(gou)(gou)、先(xian)導活(huo)塞結(jie)構(gou)(gou)。 3、電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)按照功能(neng)分類：水用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、蒸(zheng)汽電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、制冷電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、低(di)溫電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、燃氣(qi)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、消防(fang)(fang)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、氣(qi)體電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)體電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、微型電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、脈沖(chong)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa) 常開電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、油用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、直(zhi)流(liu)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、高壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)、防(fang)(fang)爆電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)等。 意(yi)大利ATOS電磁閥型號表： DHU-0610/A-X 24DC 20
