意大利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(ci)閥從原理上分(fen)為三(san)大類: 1)ATOS直動(dong)式電磁閥(fa): ATOS電(dian)磁(ci)閥(fa)(fa)原(yuan)理:通電(dian)時,電(dian)磁(ci)線圈產生電(dian)磁(ci)力把(ba)關閉(bi)件從閥(fa)(fa)座上(shang)提起(qi),閥(fa)(fa)門(men)打開;斷電(dian)時,電(dian)磁(ci)力消(xiao)失,彈簧(huang)把(ba)關閉(bi)件壓在(zai)閥(fa)(fa)座上(shang),閥(fa)(fa)門(men)關閉(bi)。 ATOS電磁閥特點:在真空、負壓、零壓時能正常工(gong)作,但通徑一(yi)般不超過25mm。 2)分步(bu)直動(dong)式電磁閥: ATOS電(dian)磁閥(fa)原理(li):它是一種直動和先(xian)導(dao)式相結合的(de)原理(li),當(dang)入(ru)(ru)口與出(chu)口沒有壓(ya)差時,通電(dian)后,電(dian)磁力(li)(li)直接(jie)把先(xian)導(dao)小閥(fa)和主(zhu)閥(fa)關閉件依(yi)次(ci)向上(shang)(shang)提起,閥(fa)門(men)(men)打開。當(dang)入(ru)(ru)口與出(chu)口達到啟動壓(ya)差時,通電(dian)后,電(dian)磁力(li)(li)先(xian)導(dao)小閥(fa),主(zhu)閥(fa)下(xia)(xia)腔壓(ya)力(li)(li)上(shang)(shang)升,上(shang)(shang)腔壓(ya)力(li)(li)下(xia)(xia)降,從而(er)利用壓(ya)差把主(zhu)閥(fa)向上(shang)(shang)推開;斷(duan)電(dian)時,先(xian)導(dao)閥(fa)利用彈簧力(li)(li)或介質壓(ya)力(li)(li)推動關閉件,向下(xia)(xia)移動,使閥(fa)門(men)(men)關閉。 ATOS電磁閥特點:在零壓(ya)(ya)差(cha)或(huo)真空、高(gao)壓(ya)(ya)時亦能(neng)可*動作,但功(gong)率較大(da),要求必須水平安裝。 3)先導(dao)式電磁閥: ATOS電(dian)(dian)(dian)磁(ci)閥(fa)原理:通(tong)電(dian)(dian)(dian)時,電(dian)(dian)(dian)磁(ci)力(li)(li)(li)把先導孔(kong)打開,上(shang)腔(qiang)室壓(ya)力(li)(li)(li)迅速(su)下(xia)降,在(zai)關 閉(bi)(bi)件(jian)周圍形(xing)成(cheng)上(shang)低下(xia)高(gao)的(de)壓(ya)差,流(liu)體壓(ya)力(li)(li)(li)推動(dong)(dong)(dong)關閉(bi)(bi)件(jian)向(xiang)上(shang)移動(dong)(dong)(dong),閥(fa)門(men)打開;斷電(dian)(dian)(dian)時,彈簧力(li)(li)(li)把先導孔(kong)關閉(bi)(bi),入口壓(ya)力(li)(li)(li)通(tong)過(guo)旁(pang)通(tong)孔(kong)迅速(su)腔(qiang)室在(zai)關閥(fa)件(jian)周圍形(xing)成(cheng)下(xia)低上(shang)高(gao)的(de)壓(ya)差,流(liu)體壓(ya)力(li)(li)(li)推動(dong)(dong)(dong)關閉(bi)(bi)件(jian)向(xiang)下(xia)移動(dong)(dong)(dong),關閉(bi)(bi)閥(fa)門(men)。 ATOS電(dian)磁閥特點:流(liu)體(ti)壓(ya)力范圍(wei)上限較高(gao),可任(ren)意安裝(zhuang)(需定(ding)制)但必(bi)須滿足流(liu)體(ti)壓(ya)差(cha)條件。 2、電(dian)磁閥(fa)從閥(fa)結(jie)(jie)(jie)構(gou)(gou)和材(cai)料上的(de)(de)不同(tong)與(yu)原理上的(de)(de)區別(bie),分(fen)(fen)為六個分(fen)(fen)支小(xiao)類:直動(dong)(dong)膜(mo)片(pian)結(jie)(jie)(jie)構(gou)(gou)、分(fen)(fen)步(bu)直動(dong)(dong)膜(mo)片(pian)結(jie)(jie)(jie)構(gou)(gou)、先(xian)導膜(mo)片(pian)結(jie)(jie)(jie)構(gou)(gou)、直動(dong)(dong)活(huo)塞(sai)(sai)(sai)結(jie)(jie)(jie)構(gou)(gou)、分(fen)(fen)步(bu)直動(dong)(dong)活(huo)塞(sai)(sai)(sai)結(jie)(jie)(jie)構(gou)(gou)、先(xian)導活(huo)塞(sai)(sai)(sai)結(jie)(jie)(jie)構(gou)(gou)。 3、電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)按照(zhao)功能(neng)分(fen)類:水用電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、蒸汽電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、制冷電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、低溫電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、燃氣電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、消(xiao)防(fang)(fang)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、氨用電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、氣體(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、液體(ti)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、微型(xing)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、脈沖電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、液壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa) 常開電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、油用電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、直(zhi)流電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、高壓(ya)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)、防(fang)(fang)爆電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)等(deng)。 意大利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 |
