意大利ATOS電磁閥的工作原理 ATOS電磁(ci)閥里有密閉(bi)的(de)腔,在(zai)不(bu)同(tong)(tong)位(wei)置(zhi)開有通(tong)(tong)(tong)孔,每個孔連接不(bu)同(tong)(tong)的(de)油(you)(you)管,腔中間是(shi)活塞(sai),兩面是(shi)兩塊電磁(ci)鐵(tie),哪面的(de)磁(ci)鐵(tie)線圈通(tong)(tong)(tong)電閥體就(jiu)(jiu)會(hui)被吸引(yin)到哪邊,通(tong)(tong)(tong)過控(kong)制(zhi)閥體的(de)移動來開啟或關閉(bi)不(bu)同(tong)(tong)的(de)排油(you)(you)孔,而進油(you)(you)孔是(shi)常開的(de),液壓(ya)油(you)(you)就(jiu)(jiu)會(hui)進入不(bu)同(tong)(tong)的(de)排油(you)(you)管,然后通(tong)(tong)(tong)過油(you)(you)的(de)壓(ya)力來推動油(you)(you)缸的(de)活塞(sai),活塞(sai)又帶(dai)動活塞(sai)桿(gan)(gan),活塞(sai)桿(gan)(gan)帶(dai)動機械裝置(zhi)。這(zhe)樣通(tong)(tong)(tong)過控(kong)制(zhi)電磁(ci)鐵(tie)的(de)電流通(tong)(tong)(tong)斷(duan)就(jiu)(jiu)控(kong)制(zhi)了機械運動。 ATOS電磁閥主要(yao)分類: 1、ATOS電磁閥從原理上分為三大類: 1)直動式(shi)電磁(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(dong)式電磁閥: ATOS電(dian)磁閥原理:它是(shi)一種直(zhi)動(dong)和先導(dao)式相結(jie)合的原理,當(dang)入口(kou)與(yu)出口(kou)沒有壓(ya)(ya)差時,通電(dian)后(hou),電(dian)磁力直(zhi)接把(ba)先導(dao)小閥和主(zhu)閥關閉(bi)件依次(ci)向(xiang)上(shang)提起(qi),閥門打開(kai)。當(dang)入口(kou)與(yu)出口(kou)達到啟動(dong)壓(ya)(ya)差時,通電(dian)后(hou),電(dian)磁力先導(dao)小閥,主(zhu)閥下(xia)腔(qiang)壓(ya)(ya)力上(shang)升(sheng),上(shang)腔(qiang)壓(ya)(ya)力下(xia)降,從(cong)而利(li)用壓(ya)(ya)差把(ba)主(zhu)閥向(xiang)上(shang)推開(kai);斷電(dian)時,先導(dao)閥利(li)用彈(dan)簧力或介(jie)質壓(ya)(ya)力推動(dong)關閉(bi)件,向(xiang)下(xia)移(yi)動(dong),使閥門關閉(bi)。 ATOS電磁(ci)閥特(te)點:在零壓差或真空、高壓時亦能(neng)可*動作,但功(gong)率較大,要(yao)求必須(xu)水平安裝(zhuang)。 3)先導式電(dian)磁閥: ATOS電磁閥原理:通電時(shi),電磁力(li)把先(xian)(xian)導孔(kong)(kong)打開(kai),上腔室壓(ya)(ya)力(li)迅速下(xia)降,在(zai)關(guan)閉件(jian)(jian)周圍形(xing)成上低下(xia)高的壓(ya)(ya)差,流體(ti)壓(ya)(ya)力(li)推(tui)(tui)動關(guan)閉件(jian)(jian)向上移(yi)(yi)動,閥門打開(kai);斷電時(shi),彈(dan)簧力(li)把先(xian)(xian)導孔(kong)(kong)關(guan)閉,入(ru)口壓(ya)(ya)力(li)通過旁通孔(kong)(kong)迅速腔室在(zai)關(guan)閥件(jian)(jian)周圍形(xing)成下(xia)低上高的壓(ya)(ya)差,流體(ti)壓(ya)(ya)力(li)推(tui)(tui)動關(guan)閉件(jian)(jian)向下(xia)移(yi)(yi)動,關(guan)閉閥門。 ATOS電磁(ci)閥(fa)特點: 流體(ti)(ti)壓(ya)力范圍上限較高,可任(ren)意安裝(需(xu)定(ding)制)但必須(xu)滿足流體(ti)(ti)壓(ya)差(cha)條件。 意(yi)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 |
