意大利ATOS電磁閥的工作原理 ATOS電磁(ci)閥里(li)有(you)密閉的(de)(de)腔(qiang)(qiang),在不(bu)同(tong)位置開有(you)通孔,每(mei)個孔連接不(bu)同(tong)的(de)(de)油(you)(you)管,腔(qiang)(qiang)中間是(shi)活塞(sai),兩面是(shi)兩塊電磁(ci)鐵(tie),哪面的(de)(de)磁(ci)鐵(tie)線圈(quan)通電閥體就會被吸(xi)引到(dao)哪邊,通過(guo)控(kong)制(zhi)閥體的(de)(de)移動(dong)來(lai)開啟或(huo)關閉不(bu)同(tong)的(de)(de)排油(you)(you)孔,而進(jin)油(you)(you)孔是(shi)常(chang)開的(de)(de),液壓油(you)(you)就會進(jin)入不(bu)同(tong)的(de)(de)排油(you)(you)管,然后通過(guo)油(you)(you)的(de)(de)壓力來(lai)推(tui)動(dong)油(you)(you)缸的(de)(de)活塞(sai),活塞(sai)又帶動(dong)活塞(sai)桿(gan),活塞(sai)桿(gan)帶動(dong)機械裝(zhuang)置。這樣通過(guo)控(kong)制(zhi)電磁(ci)鐵(tie)的(de)(de)電流通斷就控(kong)制(zhi)了機械運動(dong)。 ATOS電磁閥主(zhu)要分類: 1、ATOS電磁(ci)閥從原理上(shang)分(fen)為三大類(lei): 1)直動式(shi)電磁閥(fa): ATOS電磁閥原理:通電時,電磁線圈產生電磁力把關閉件從閥座上提起,閥門打開;斷電時,電磁力消失,彈簧把關閉件壓在閥座上,閥門關閉。 ATOS電磁閥特點:在真空、負壓、零壓時能正常工作,但通徑一般不超過25mm。 2)分步(bu)直動式電(dian)磁閥: ATOS電(dian)磁(ci)閥原理(li):它是一種直動(dong)(dong)和(he)先(xian)(xian)導式相(xiang)結合的原理(li),當(dang)入口與(yu)出(chu)口沒(mei)有(you)壓(ya)(ya)差(cha)時(shi)(shi),通電(dian)后,電(dian)磁(ci)力直接把先(xian)(xian)導小閥和(he)主(zhu)閥關(guan)閉件(jian)依次向(xiang)上提起(qi),閥門打開。當(dang)入口與(yu)出(chu)口達(da)到啟動(dong)(dong)壓(ya)(ya)差(cha)時(shi)(shi),通電(dian)后,電(dian)磁(ci)力先(xian)(xian)導小閥,主(zhu)閥下腔壓(ya)(ya)力上升,上腔壓(ya)(ya)力下降(jiang),從而利(li)用(yong)壓(ya)(ya)差(cha)把主(zhu)閥向(xiang)上推(tui)開;斷(duan)電(dian)時(shi)(shi),先(xian)(xian)導閥利(li)用(yong)彈(dan)簧(huang)力或介質壓(ya)(ya)力推(tui)動(dong)(dong)關(guan)閉件(jian),向(xiang)下移動(dong)(dong),使閥門關(guan)閉。 ATOS電磁閥(fa)特點:在零壓(ya)差或真(zhen)空、高壓(ya)時亦(yi)能可*動作,但功率較大,要求必須(xu)水(shui)平安裝。 3)先導式(shi)電(dian)磁閥(fa): ATOS電(dian)(dian)磁閥原理:通電(dian)(dian)時,電(dian)(dian)磁力(li)把先導孔(kong)打(da)開,上(shang)腔(qiang)室壓(ya)(ya)(ya)力(li)迅速下(xia)(xia)降(jiang),在(zai)(zai)關(guan)閉件周圍(wei)形成上(shang)低(di)下(xia)(xia)高(gao)的壓(ya)(ya)(ya)差,流體(ti)壓(ya)(ya)(ya)力(li)推(tui)動關(guan)閉件向上(shang)移動,閥門打(da)開;斷電(dian)(dian)時,彈簧力(li)把先導孔(kong)關(guan)閉,入(ru)口壓(ya)(ya)(ya)力(li)通過旁通孔(kong)迅速腔(qiang)室在(zai)(zai)關(guan)閥件周圍(wei)形成下(xia)(xia)低(di)上(shang)高(gao)的壓(ya)(ya)(ya)差,流體(ti)壓(ya)(ya)(ya)力(li)推(tui)動關(guan)閉件向下(xia)(xia)移動,關(guan)閉閥門。 ATOS電(dian)磁閥特(te)點(dian): 流(liu)體壓力(li)范圍上限(xian)較高,可任(ren)意安裝(需定制)但必須滿足流(liu)體壓差(cha)條件。 意大(da)利阿(a)托斯ATOS電磁閥現貨: DHI-0713-X 230/50/60AC DHI-0713-X 24DC DHI-0713-X 24DC 23 /PE DHI-0714/WP-X 230/50/60AC DHI-0714/WP-X 230/50/60AC 23 /PE DHI-0714-X 230/50/60AC DHI-0714-X 24DC DHI-0715/FI/NC-X 24DC DHI-0715-X 24DC DHI-0716-X 24DC DHI-0717-X 24DC DHI-0718-X 230/50/60AC DHI-0718-X 24DC DHI-0750/2-X 24DC DHI-0751/2/FI/NC-X 24DC 23 DHI-0751/2/FI/NO-X 24DC 23 DHI-0751/2/WP-X 230/50/60AC DHI-0751/2/WP-X 230/50/60AC 23 /PE DHI-0751/2/WP-X 24DC DHI-0751/2-X 110/50/60AC 23 DHI-0751/2-X 230/50/60AC DHI-0751/2-X 24DC |
