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(dian)磁閥從原理上分為(wei)三大類: 1)ATOS直動式電磁(ci)閥: ATOS電(dian)磁閥原(yuan)理(li):通電(dian)時(shi),電(dian)磁線(xian)圈產生電(dian)磁力把(ba)關閉(bi)(bi)件從(cong)閥座上提起(qi),閥門打(da)開;斷(duan)電(dian)時(shi),電(dian)磁力消失,彈簧把(ba)關閉(bi)(bi)件壓在(zai)閥座上,閥門關閉(bi)(bi)。 ATOS電磁閥特點(dian):在真空、負壓、零壓時能(neng)正常工作,但通徑一般(ban)不超過25mm。 2)分步直動(dong)式(shi)電磁(ci)閥: ATOS電(dian)磁(ci)閥(fa)(fa)原理(li):它是一種直(zhi)動和先(xian)導(dao)式相結合(he)的原理(li),當入(ru)口(kou)與出口(kou)沒有壓(ya)(ya)(ya)(ya)差時,通電(dian)后,電(dian)磁(ci)力(li)(li)直(zhi)接把先(xian)導(dao)小閥(fa)(fa)和主閥(fa)(fa)關(guan)閉(bi)件依次向(xiang)上提起,閥(fa)(fa)門(men)打開。當入(ru)口(kou)與出口(kou)達到啟動壓(ya)(ya)(ya)(ya)差時,通電(dian)后,電(dian)磁(ci)力(li)(li)先(xian)導(dao)小閥(fa)(fa),主閥(fa)(fa)下(xia)腔壓(ya)(ya)(ya)(ya)力(li)(li)上升(sheng),上腔壓(ya)(ya)(ya)(ya)力(li)(li)下(xia)降(jiang),從而利用(yong)壓(ya)(ya)(ya)(ya)差把主閥(fa)(fa)向(xiang)上推開;斷(duan)電(dian)時,先(xian)導(dao)閥(fa)(fa)利用(yong)彈簧(huang)力(li)(li)或(huo)介質壓(ya)(ya)(ya)(ya)力(li)(li)推動關(guan)閉(bi)件,向(xiang)下(xia)移動,使閥(fa)(fa)門(men)關(guan)閉(bi)。 ATOS電磁閥特點:在零壓差或真空(kong)、高壓時亦能可*動作,但功(gong)率較大,要求必須(xu)水平安裝。 3)先導式電磁閥: ATOS電(dian)(dian)(dian)(dian)磁(ci)閥原理:通電(dian)(dian)(dian)(dian)時,電(dian)(dian)(dian)(dian)磁(ci)力(li)把先導孔打(da)開(kai)(kai),上腔室壓力(li)迅速下(xia)降,在(zai)關(guan)(guan) 閉件周(zhou)圍(wei)形成上低下(xia)高的壓差,流體壓力(li)推(tui)動關(guan)(guan)閉件向上移動,閥門(men)打(da)開(kai)(kai);斷(duan)電(dian)(dian)(dian)(dian)時,彈簧力(li)把先導孔關(guan)(guan)閉,入口壓力(li)通過旁通孔迅速腔室在(zai)關(guan)(guan)閥件周(zhou)圍(wei)形成下(xia)低上高的壓差,流體壓力(li)推(tui)動關(guan)(guan)閉件向下(xia)移動,關(guan)(guan)閉閥門(men)。 ATOS電磁閥特點:流(liu)體壓力范圍上限較高,可任意(yi)安裝(zhuang)(需定制)但必須滿足流(liu)體壓差條件。 2、電磁閥從閥結(jie)構(gou)和材料上的(de)不同與(yu)原理上的(de)區別,分(fen)(fen)為六個分(fen)(fen)支(zhi)小(xiao)類:直(zhi)動(dong)膜片結(jie)構(gou)、分(fen)(fen)步直(zhi)動(dong)膜片結(jie)構(gou)、先導(dao)膜片結(jie)構(gou)、直(zhi)動(dong)活塞(sai)結(jie)構(gou)、分(fen)(fen)步直(zhi)動(dong)活塞(sai)結(jie)構(gou)、先導(dao)活塞(sai)結(jie)構(gou)。 3、電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)按照(zhao)功能(neng)分類:水用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、制冷電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、低(di)溫電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、燃(ran)氣電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、消(xiao)防電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、氣體電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、液體電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、液壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa) 常(chang)開(kai)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、油用(yong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、直(zhi)流電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、高壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)、防爆電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)(fa)(fa)等。 意大(da)利ATOS電磁閥型號表: DHU-0610/A-X 24DC 20 DHU-0610/FI/NC-X 24DC 20 DHU-0610-X 24DC 20 DHU-0610-X 48DC 20 DHU-0611-X 24DC DHU-0614/A-X 24DC 20 DHU-0614-X 24DC 20 DHU-06191-X 24DC 20 DHU-06194-X 24DC 20 DHU-0630/2/A-X 24DC DHU-0630/2-X 24DC DHU-0631/2/A-X 24DC DHU-0631/2/FC-X 24DC 20 DHU-0631/2-X 24DC DHU-0632/2/A-X 24DC 20 DHU-0632/2-X 24DC 20 DHU-0639/C-X 24DC 20 DHU-0671-X 24DC DHU-0710/L1-X 24DC 20 DHU-0710-X 24DC DHU-0711/WP-X 24DC 20 DHU-07119-X 24DC 20 DHU-0711-X 24DC DHU-0713/1-X 24DC DHU-0713/WP-X 24DC 20 DHU-0713P-X 24DC 20 DHU-0713-X 24DC DHU-07149-X 24DC 20 DHU-0714-X 24DC DHU-0718-X 24DC DHU-0750/2/FI/NC-X 24DC 20 DHU-0750/2-X 24DC DHU-0751/2-00 20 /WG DHU-0751/2P-X 24DC 20 DHU-0751/2-X 24DC DHU-6751/2P-X 24DC |
