ATOS電磁換向閥里有密閉的腔，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三大類： 1）ATOS直動式電磁閥： ATOS電(dian)(dian)(dian)磁(ci)閥(fa)原理：通電(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)磁(ci)線(xian)圈產生電(dian)(dian)(dian)磁(ci)力把關(guan)閉件(jian)從閥(fa)座上(shang)提起(qi)，閥(fa)門打開(kai)；斷電(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)磁(ci)力消失，彈簧把關(guan)閉件(jian)壓在閥(fa)座上(shang)，閥(fa)門關(guan)閉。 ATOS電磁閥特(te)點：在真空(kong)、負壓、零壓時能正常(chang)工作，但(dan)通徑一般不超過25mm。 2）分步直動式電(dian)磁閥(fa)： ATOS電(dian)(dian)(dian)(dian)磁(ci)閥(fa)原(yuan)理：它(ta)是一種(zhong)直(zhi)動和先(xian)導(dao)式相結合的原(yuan)理，當(dang)入口(kou)(kou)與出口(kou)(kou)沒有壓(ya)(ya)差時，通(tong)電(dian)(dian)(dian)(dian)后，電(dian)(dian)(dian)(dian)磁(ci)力(li)直(zhi)接把先(xian)導(dao)小閥(fa)和主閥(fa)關閉(bi)件依次(ci)向(xiang)上(shang)(shang)提(ti)起，閥(fa)門打開(kai)(kai)。當(dang)入口(kou)(kou)與出口(kou)(kou)達到啟動壓(ya)(ya)差時，通(tong)電(dian)(dian)(dian)(dian)后，電(dian)(dian)(dian)(dian)磁(ci)力(li)先(xian)導(dao)小閥(fa)，主閥(fa)下腔壓(ya)(ya)力(li)上(shang)(shang)升，上(shang)(shang)腔壓(ya)(ya)力(li)下降，從而利(li)用壓(ya)(ya)差把主閥(fa)向(xiang)上(shang)(shang)推開(kai)(kai)；斷(duan)電(dian)(dian)(dian)(dian)時，先(xian)導(dao)閥(fa)利(li)用彈簧力(li)或介質壓(ya)(ya)力(li)推動關閉(bi)件，向(xiang)下移動，使閥(fa)門關閉(bi)。 ATOS電磁閥特點：在零壓差或真(zhen)空、高壓時亦能可*動作，但功率較大，要求(qiu)必須(xu)水平安裝。 3）先導式電(dian)磁(ci)閥： ATOS電(dian)磁閥原理：通(tong)電(dian)時，電(dian)磁力把先導孔(kong)(kong)打開，上(shang)腔室壓(ya)力迅(xun)(xun)速下(xia)降，在關(guan) 閉件周圍形(xing)成上(shang)低下(xia)高的(de)壓(ya)差(cha)，流體壓(ya)力推動(dong)(dong)關(guan)閉件向上(shang)移(yi)動(dong)(dong)，閥門打開；斷(duan)電(dian)時，彈簧(huang)力把先導孔(kong)(kong)關(guan)閉，入口壓(ya)力通(tong)過旁通(tong)孔(kong)(kong)迅(xun)(xun)速腔室在關(guan)閥件周圍形(xing)成下(xia)低上(shang)高的(de)壓(ya)差(cha)，流體壓(ya)力推動(dong)(dong)關(guan)閉件向下(xia)移(yi)動(dong)(dong)，關(guan)閉閥門。 ATOS電磁閥特(te)點：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。 2、電(dian)磁閥從閥結(jie)(jie)構和(he)材(cai)料上的不同與(yu)原理上的區別(bie)，分為六(liu)個分支(zhi)小類(lei)：直(zhi)(zhi)動膜片(pian)結(jie)(jie)構、分步直(zhi)(zhi)動膜片(pian)結(jie)(jie)構、先導膜片(pian)結(jie)(jie)構、直(zhi)(zhi)動活塞(sai)結(jie)(jie)構、分步直(zhi)(zhi)動活塞(sai)結(jie)(jie)構、先導活塞(sai)結(jie)(jie)構。 3、電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)按照功能分類(lei)：水用(yong)(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、蒸汽電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、制冷(leng)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、低(di)溫(wen)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、燃氣(qi)(qi)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、消防電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、氨(an)用(yong)(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、氣(qi)(qi)體電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、液(ye)體電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、微型電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、脈沖電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、液(ye)壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa) 常開電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、油用(yong)(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、直流電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、高(gao)壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、防爆(bao)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)等(deng)。 意大利ATOS電磁閥型號表： DHI-0713-X 24DC
