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電磁閥從原理上分為三(san)大類: 1)ATOS直動(dong)式(shi)電磁閥(fa): ATOS電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)原理:通(tong)電(dian)(dian)時,電(dian)(dian)磁(ci)(ci)線圈產生電(dian)(dian)磁(ci)(ci)力(li)把(ba)關閉(bi)件從閥(fa)(fa)(fa)(fa)座上提(ti)起,閥(fa)(fa)(fa)(fa)門打開;斷電(dian)(dian)時,電(dian)(dian)磁(ci)(ci)力(li)消失,彈簧把(ba)關閉(bi)件壓(ya)在閥(fa)(fa)(fa)(fa)座上,閥(fa)(fa)(fa)(fa)門關閉(bi)。 ATOS電磁閥特點:在真空、負壓、零(ling)壓時能正(zheng)常工作,但通(tong)徑一般不超過25mm。 2)分步直動(dong)式(shi)電磁閥: ATOS電(dian)(dian)磁(ci)閥(fa)(fa)(fa)(fa)原理(li):它是一種直動(dong)和先導(dao)式(shi)相結(jie)合的原理(li),當入(ru)口(kou)(kou)(kou)與(yu)出口(kou)(kou)(kou)沒有壓(ya)(ya)差時,通電(dian)(dian)后(hou),電(dian)(dian)磁(ci)力直接(jie)把先導(dao)小閥(fa)(fa)(fa)(fa)和主(zhu)閥(fa)(fa)(fa)(fa)關(guan)閉(bi)件依(yi)次向(xiang)上(shang)提起(qi),閥(fa)(fa)(fa)(fa)門(men)打開(kai)。當入(ru)口(kou)(kou)(kou)與(yu)出口(kou)(kou)(kou)達到(dao)啟動(dong)壓(ya)(ya)差時,通電(dian)(dian)后(hou),電(dian)(dian)磁(ci)力先導(dao)小閥(fa)(fa)(fa)(fa),主(zhu)閥(fa)(fa)(fa)(fa)下(xia)腔(qiang)壓(ya)(ya)力上(shang)升,上(shang)腔(qiang)壓(ya)(ya)力下(xia)降,從而(er)利用壓(ya)(ya)差把主(zhu)閥(fa)(fa)(fa)(fa)向(xiang)上(shang)推開(kai);斷(duan)電(dian)(dian)時,先導(dao)閥(fa)(fa)(fa)(fa)利用彈(dan)簧力或(huo)介質壓(ya)(ya)力推動(dong)關(guan)閉(bi)件,向(xiang)下(xia)移(yi)動(dong),使閥(fa)(fa)(fa)(fa)門(men)關(guan)閉(bi)。 ATOS電磁閥(fa)特點:在零壓(ya)差或真空(kong)、高壓(ya)時亦(yi)能可*動作,但功率較大(da),要(yao)求必須(xu)水平(ping)安裝。 3)先導式(shi)電(dian)磁閥: ATOS電(dian)磁閥(fa)(fa)原理:通(tong)電(dian)時,電(dian)磁力(li)(li)把先導孔(kong)打開,上(shang)腔室(shi)壓(ya)力(li)(li)迅(xun)速(su)下(xia)降,在關(guan) 閉(bi)件周圍形(xing)(xing)成上(shang)低下(xia)高(gao)的壓(ya)差(cha),流體壓(ya)力(li)(li)推動關(guan)閉(bi)件向上(shang)移動,閥(fa)(fa)門打開;斷電(dian)時,彈簧力(li)(li)把先導孔(kong)關(guan)閉(bi),入口壓(ya)力(li)(li)通(tong)過旁通(tong)孔(kong)迅(xun)速(su)腔室(shi)在關(guan)閥(fa)(fa)件周圍形(xing)(xing)成下(xia)低上(shang)高(gao)的壓(ya)差(cha),流體壓(ya)力(li)(li)推動關(guan)閉(bi)件向下(xia)移動,關(guan)閉(bi)閥(fa)(fa)門。 ATOS電磁閥特點:流(liu)體壓力(li)范圍上限較高,可任意安裝(需定制)但(dan)必須(xu)滿足流(liu)體壓差條件(jian)。 2、電磁閥從閥結(jie)構(gou)(gou)和材料上的不同與原理上的區(qu)別,分(fen)為(wei)六個(ge)分(fen)支小類(lei):直(zhi)動(dong)膜片(pian)結(jie)構(gou)(gou)、分(fen)步(bu)直(zhi)動(dong)膜片(pian)結(jie)構(gou)(gou)、先導(dao)膜片(pian)結(jie)構(gou)(gou)、直(zhi)動(dong)活(huo)塞(sai)結(jie)構(gou)(gou)、分(fen)步(bu)直(zhi)動(dong)活(huo)塞(sai)結(jie)構(gou)(gou)、先導(dao)活(huo)塞(sai)結(jie)構(gou)(gou)。 3、電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)按照(zhao)功(gong)能分類:水(shui)用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、蒸(zheng)汽電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、制冷電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、低(di)溫(wen)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、消防電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氨用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氣體(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)體(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、微型電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液(ye)壓電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa) 常開(kai)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、油(you)用電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、直流電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、高壓電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、防爆電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)等。 意(yi)大利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 |
