意大利ATOS電磁閥的工作原理 ATOS電(dian)磁閥(fa)(fa)里有(you)密閉的腔(qiang),在(zai)不同位置(zhi)開有(you)通(tong)孔,每個孔連(lian)接不同的油(you)管(guan),腔(qiang)中(zhong)間是(shi)活(huo)(huo)塞(sai)(sai),兩(liang)面(mian)(mian)是(shi)兩(liang)塊(kuai)電(dian)磁鐵,哪(na)面(mian)(mian)的磁鐵線圈通(tong)電(dian)閥(fa)(fa)體就(jiu)會被吸引到哪(na)邊,通(tong)過(guo)控(kong)制(zhi)閥(fa)(fa)體的移(yi)動(dong)來(lai)(lai)開啟或(huo)關(guan)閉不同的排(pai)油(you)孔,而(er)進油(you)孔是(shi)常開的,液壓油(you)就(jiu)會進入不同的排(pai)油(you)管(guan),然后通(tong)過(guo)油(you)的壓力來(lai)(lai)推動(dong)油(you)缸的活(huo)(huo)塞(sai)(sai),活(huo)(huo)塞(sai)(sai)又帶(dai)動(dong)活(huo)(huo)塞(sai)(sai)桿,活(huo)(huo)塞(sai)(sai)桿帶(dai)動(dong)機械裝置(zhi)。這(zhe)樣通(tong)過(guo)控(kong)制(zhi)電(dian)磁鐵的電(dian)流通(tong)斷(duan)就(jiu)控(kong)制(zhi)了機械運動(dong)。 ATOS電磁閥主要分類(lei): 1、ATOS電磁閥(fa)從原理上分為(wei)三(san)大類: 1)直動式電(dian)磁(ci)閥: 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)分步直動式電磁閥: ATOS電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)原理(li):它是一種直動(dong)和先(xian)(xian)導(dao)式相結合的原理(li),當(dang)(dang)入口與出口沒有壓(ya)(ya)差(cha)(cha)時(shi),通電(dian)(dian)(dian)后,電(dian)(dian)(dian)磁(ci)(ci)力直接把(ba)先(xian)(xian)導(dao)小閥(fa)(fa)(fa)和主(zhu)閥(fa)(fa)(fa)關閉件依(yi)次向(xiang)(xiang)上(shang)提起,閥(fa)(fa)(fa)門打開(kai)。當(dang)(dang)入口與出口達到啟動(dong)壓(ya)(ya)差(cha)(cha)時(shi),通電(dian)(dian)(dian)后,電(dian)(dian)(dian)磁(ci)(ci)力先(xian)(xian)導(dao)小閥(fa)(fa)(fa),主(zhu)閥(fa)(fa)(fa)下腔壓(ya)(ya)力上(shang)升,上(shang)腔壓(ya)(ya)力下降,從而利(li)用壓(ya)(ya)差(cha)(cha)把(ba)主(zhu)閥(fa)(fa)(fa)向(xiang)(xiang)上(shang)推開(kai);斷電(dian)(dian)(dian)時(shi),先(xian)(xian)導(dao)閥(fa)(fa)(fa)利(li)用彈簧力或介質壓(ya)(ya)力推動(dong)關閉件,向(xiang)(xiang)下移動(dong),使閥(fa)(fa)(fa)門關閉。 ATOS電磁閥特(te)點(dian):在(zai)零壓差或真空、高(gao)壓時亦能可*動作,但功率較大,要(yao)求必須(xu)水平安裝。 3)先導式電磁(ci)閥: ATOS電(dian)磁(ci)(ci)閥(fa)原(yuan)理:通(tong)電(dian)時,電(dian)磁(ci)(ci)力(li)把先(xian)(xian)導孔(kong)打(da)開(kai),上(shang)腔室(shi)壓(ya)力(li)迅速下降,在(zai)(zai)關(guan)閉(bi)件(jian)(jian)周(zhou)圍形(xing)成上(shang)低(di)下高的壓(ya)差,流體(ti)壓(ya)力(li)推動(dong)關(guan)閉(bi)件(jian)(jian)向(xiang)上(shang)移動(dong),閥(fa)門(men)(men)打(da)開(kai);斷電(dian)時,彈(dan)簧力(li)把先(xian)(xian)導孔(kong)關(guan)閉(bi),入口壓(ya)力(li)通(tong)過旁通(tong)孔(kong)迅速腔室(shi)在(zai)(zai)關(guan)閥(fa)件(jian)(jian)周(zhou)圍形(xing)成下低(di)上(shang)高的壓(ya)差,流體(ti)壓(ya)力(li)推動(dong)關(guan)閉(bi)件(jian)(jian)向(xiang)下移動(dong),關(guan)閉(bi)閥(fa)門(men)(men)。 ATOS電磁閥特點(dian): 流體壓力范圍上限較(jiao)高,可任意安裝(需定制)但必須滿足流體壓差條件。 意大利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 |
