意大利阿托斯電磁閥DKE-1631/2DC10的原理：

阿托斯電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)里有(you)(you)密(mi)閉(bi)的(de)腔，在(zai)的(de)不同位置開有(you)(you)通(tong)(tong)(tong)(tong)孔(kong)，每個孔(kong)都(dou)通(tong)(tong)(tong)(tong)向不同的(de)油(you)(you)管，腔中間是閥(fa)，兩面是兩塊(kuai)電(dian)(dian)(dian)(dian)磁(ci)(ci)鐵(tie)(tie)，哪面的(de)磁(ci)(ci)鐵(tie)(tie)線圈(quan)通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)閥(fa)體(ti)就會被吸引(yin)到哪邊(bian)，通(tong)(tong)(tong)(tong)過控(kong)制閥(fa)體(ti)的(de)移動來(lai)檔(dang)住或漏出(chu)不同的(de)排油(you)(you)的(de)孔(kong)，而(er)進油(you)(you)孔(kong)是常開的(de)，液(ye)壓油(you)(you)就會進入(ru)不同的(de)排油(you)(you)管，然(ran)后(hou)通(tong)(tong)(tong)(tong)過油(you)(you)的(de)壓力(li)來(lai)推動油(you)(you)剛的(de)活(huo)塞(sai)，活(huo)塞(sai)又帶動活(huo)塞(sai)桿，活(huo)塞(sai)竿帶動機械裝置動。這樣通(tong)(tong)(tong)(tong)過控(kong)制電(dian)(dian)(dian)(dian)磁(ci)(ci)鐵(tie)(tie)的(de)電(dian)(dian)(dian)(dian)流就控(kong)制了機械運動直動式(shi)電(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)： 原(yuan)理：通(tong)(tong)(tong)(tong)電(dian)(dian)(dian)(dian)時，電(dian)(dian)(dian)(dian)磁(ci)(ci)線圈(quan)產生(sheng)電(dian)(dian)(dian)(dian)磁(ci)(ci)力(li)把關閉(bi)件(jian)從(cong)閥(fa)座上(shang)(shang)提(ti)起，閥(fa)門打開；斷電(dian)(dian)(dian)(dian)時，電(dian)(dian)(dian)(dian)磁(ci)(ci)力(li)消(xiao)失(shi)，彈簧把關閉(bi)件(jian)壓在(zai)閥(fa)座上(shang)(shang)，閥(fa)門關閉(bi)。 

特點(dian)(dian)：在(zai)(zai)真(zhen)空、負壓、零壓時(shi)(shi)能正(zheng)常(chang)工作，但通徑一(yi)般(ban)不超(chao)過(guo)25mm。 atos分(fen)布直動(dong)(dong)(dong)(dong)式電(dian)(dian)磁(ci)閥(fa)(fa)(fa)： 原理： 它是(shi)一(yi)種直動(dong)(dong)(dong)(dong)和先(xian)(xian)導(dao)式相結合的(de)原理，當入(ru)(ru)口與出口沒有壓差時(shi)(shi)，通電(dian)(dian)后，atos電(dian)(dian)磁(ci)力(li)(li)直接把(ba)先(xian)(xian)導(dao)小(xiao)閥(fa)(fa)(fa)和主閥(fa)(fa)(fa)關(guan)閉(bi)件(jian)依次向上(shang)(shang)提起，閥(fa)(fa)(fa)門(men)打(da)開。當入(ru)(ru)口與出口達到啟動(dong)(dong)(dong)(dong)壓差時(shi)(shi)，通電(dian)(dian)后，電(dian)(dian)磁(ci)力(li)(li)先(xian)(xian)導(dao)小(xiao)閥(fa)(fa)(fa)，主閥(fa)(fa)(fa)下(xia)腔壓力(li)(li)上(shang)(shang)升(sheng)，上(shang)(shang)腔壓力(li)(li)下(xia)降，從而利(li)用(yong)(yong)壓差把(ba)主閥(fa)(fa)(fa)向上(shang)(shang)推(tui)(tui)開；斷電(dian)(dian)時(shi)(shi)，先(xian)(xian)導(dao)閥(fa)(fa)(fa)利(li)用(yong)(yong)彈簧力(li)(li)或介質壓力(li)(li)推(tui)(tui)動(dong)(dong)(dong)(dong)關(guan)閉(bi)件(jian)，向下(xia)移動(dong)(dong)(dong)(dong)，使(shi)閥(fa)(fa)(fa)門(men)關(guan)閉(bi)。ATOS電(dian)(dian)磁(ci)閥(fa)(fa)(fa) 特點(dian)(dian)： 在(zai)(zai)零壓差或真(zhen)空、高(gao)壓時(shi)(shi)亦能可*動(dong)(dong)(dong)(dong)作，但功率(lv)較(jiao)大，要求必(bi)須(xu)(xu)水(shui)平安裝。ATOS先(xian)(xian)導(dao)式電(dian)(dian)磁(ci)閥(fa)(fa)(fa)： 原理：通電(dian)(dian)時(shi)(shi)，電(dian)(dian)磁(ci)力(li)(li)把(ba)先(xian)(xian)導(dao)孔打(da)開，上(shang)(shang)腔室壓力(li)(li)迅(xun)速下(xia)降，在(zai)(zai)關(guan)閉(bi)件(jian)周圍(wei)形成(cheng)上(shang)(shang)低(di)下(xia)高(gao)的(de)壓差，流(liu)體(ti)(ti)壓力(li)(li)推(tui)(tui)動(dong)(dong)(dong)(dong)關(guan)閉(bi)件(jian)向上(shang)(shang)移動(dong)(dong)(dong)(dong)，閥(fa)(fa)(fa)門(men)打(da)開；斷電(dian)(dian)時(shi)(shi)，彈簧力(li)(li)把(ba)先(xian)(xian)導(dao)孔關(guan)閉(bi)，入(ru)(ru)口壓力(li)(li)通過(guo)旁通孔迅(xun)速腔室在(zai)(zai)關(guan)閥(fa)(fa)(fa)件(jian)周圍(wei)形成(cheng)下(xia)低(di)上(shang)(shang)高(gao)的(de)壓差，流(liu)體(ti)(ti)壓力(li)(li)推(tui)(tui)動(dong)(dong)(dong)(dong)關(guan)閉(bi)件(jian)向下(xia)移動(dong)(dong)(dong)(dong)，關(guan)閉(bi)閥(fa)(fa)(fa)門(men)。ATOS電(dian)(dian)磁(ci)閥(fa)(fa)(fa)特點(dian)(dian)： 流(liu)體(ti)(ti)壓力(li)(li)范圍(wei)上(shang)(shang)限較(jiao)高(gao)，可任意安裝（需(xu)定制）但必(bi)須(xu)(xu)滿足流(liu)體(ti)(ti)壓差條件(jian)。
