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電磁閥從原(yuan)理上分為(wei)三大類: 1)ATOS直動式電磁閥: ATOS電磁閥(fa)原理:通(tong)電時(shi)(shi),電磁線圈產生電磁力把關閉(bi)件(jian)從閥(fa)座(zuo)上(shang)提起,閥(fa)門打開;斷電時(shi)(shi),電磁力消失(shi),彈(dan)簧把關閉(bi)件(jian)壓在閥(fa)座(zuo)上(shang),閥(fa)門關閉(bi)。 ATOS電磁閥特點:在真空、負壓、零壓時能正(zheng)常(chang)工作,但通徑一般不超(chao)過25mm。 2)分步直(zhi)動式電磁(ci)閥: ATOS電(dian)磁閥(fa)(fa)原理(li):它是一種直動和先(xian)(xian)導(dao)(dao)式(shi)相結(jie)合(he)的原理(li),當入(ru)口與出(chu)口沒(mei)有壓(ya)(ya)(ya)差(cha)時,通電(dian)后,電(dian)磁力(li)直接把(ba)先(xian)(xian)導(dao)(dao)小閥(fa)(fa)和主(zhu)閥(fa)(fa)關(guan)閉(bi)件依次(ci)向(xiang)上提(ti)起,閥(fa)(fa)門打開。當入(ru)口與出(chu)口達到啟動壓(ya)(ya)(ya)差(cha)時,通電(dian)后,電(dian)磁力(li)先(xian)(xian)導(dao)(dao)小閥(fa)(fa),主(zhu)閥(fa)(fa)下腔(qiang)壓(ya)(ya)(ya)力(li)上升,上腔(qiang)壓(ya)(ya)(ya)力(li)下降(jiang),從而利(li)用壓(ya)(ya)(ya)差(cha)把(ba)主(zhu)閥(fa)(fa)向(xiang)上推開;斷(duan)電(dian)時,先(xian)(xian)導(dao)(dao)閥(fa)(fa)利(li)用彈簧力(li)或介質壓(ya)(ya)(ya)力(li)推動關(guan)閉(bi)件,向(xiang)下移動,使閥(fa)(fa)門關(guan)閉(bi)。 ATOS電磁閥特點:在零壓差(cha)或真空(kong)、高壓時亦能可*動(dong)作,但功率較大,要求必須水(shui)平(ping)安裝(zhuang)。 3)先(xian)導式電磁閥(fa): ATOS電磁閥原理:通(tong)電時,電磁力(li)把(ba)先導(dao)孔打開(kai),上(shang)腔室(shi)壓(ya)(ya)力(li)迅速下(xia)(xia)降(jiang),在(zai)關(guan) 閉(bi)(bi)件周圍(wei)形(xing)成(cheng)上(shang)低下(xia)(xia)高(gao)的(de)壓(ya)(ya)差(cha),流(liu)體(ti)壓(ya)(ya)力(li)推動(dong)(dong)關(guan)閉(bi)(bi)件向上(shang)移(yi)動(dong)(dong),閥門(men)打開(kai);斷電時,彈簧力(li)把(ba)先導(dao)孔關(guan)閉(bi)(bi),入口壓(ya)(ya)力(li)通(tong)過旁通(tong)孔迅速腔室(shi)在(zai)關(guan)閥件周圍(wei)形(xing)成(cheng)下(xia)(xia)低上(shang)高(gao)的(de)壓(ya)(ya)差(cha),流(liu)體(ti)壓(ya)(ya)力(li)推動(dong)(dong)關(guan)閉(bi)(bi)件向下(xia)(xia)移(yi)動(dong)(dong),關(guan)閉(bi)(bi)閥門(men)。 ATOS電磁閥(fa)特(te)點:流體壓(ya)力范圍(wei)上(shang)限較高,可任意安(an)裝(zhuang)(需定制(zhi))但必須滿足流體壓(ya)差條件。 2、電磁閥從(cong)閥結構(gou)和材料(liao)上的不同與原(yuan)理上的區別,分為六個分支小類:直(zhi)動膜片結構(gou)、分步直(zhi)動膜片結構(gou)、先導(dao)膜片結構(gou)、直(zhi)動活塞結構(gou)、分步直(zhi)動活塞結構(gou)、先導(dao)活塞結構(gou)。 3、電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)按照(zhao)功(gong)能分類:水(shui)用(yong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、蒸(zheng)汽電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、制冷電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、低溫電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、燃(ran)氣電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、消防(fang)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、氣體(ti)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、液體(ti)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、微(wei)型電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、液壓電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa) 常開(kai)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、油用(yong)電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、直流電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、高壓電(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、防(fang)爆電(dian)(dian)(dian)磁(ci)(ci)閥(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 |
