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(cong)原理上分為三大類: 1)ATOS直動式電磁閥: ATOS電(dian)磁(ci)閥(fa)(fa)原理:通電(dian)時,電(dian)磁(ci)線圈產生電(dian)磁(ci)力(li)(li)把關閉件從閥(fa)(fa)座上提(ti)起,閥(fa)(fa)門打開;斷(duan)電(dian)時,電(dian)磁(ci)力(li)(li)消失,彈簧(huang)把關閉件壓在閥(fa)(fa)座上,閥(fa)(fa)門關閉。 ATOS電磁(ci)閥特點:在真(zhen)空(kong)、負(fu)壓、零壓時(shi)能正常工作,但通徑一般不(bu)超過25mm。 2)分步直(zhi)動式電磁閥: ATOS電(dian)(dian)磁閥(fa)(fa)(fa)(fa)原理(li):它(ta)是一種直動(dong)和先導(dao)式相(xiang)結合的原理(li),當(dang)入口(kou)與出(chu)口(kou)沒有壓差時(shi),通電(dian)(dian)后(hou),電(dian)(dian)磁力(li)直接(jie)把先導(dao)小閥(fa)(fa)(fa)(fa)和主(zhu)(zhu)閥(fa)(fa)(fa)(fa)關閉件(jian)依(yi)次向(xiang)(xiang)(xiang)上提起,閥(fa)(fa)(fa)(fa)門(men)打開。當(dang)入口(kou)與出(chu)口(kou)達到啟(qi)動(dong)壓差時(shi),通電(dian)(dian)后(hou),電(dian)(dian)磁力(li)先導(dao)小閥(fa)(fa)(fa)(fa),主(zhu)(zhu)閥(fa)(fa)(fa)(fa)下腔(qiang)(qiang)壓力(li)上升(sheng),上腔(qiang)(qiang)壓力(li)下降,從而利用壓差把主(zhu)(zhu)閥(fa)(fa)(fa)(fa)向(xiang)(xiang)(xiang)上推開;斷電(dian)(dian)時(shi),先導(dao)閥(fa)(fa)(fa)(fa)利用彈(dan)簧力(li)或介質壓力(li)推動(dong)關閉件(jian),向(xiang)(xiang)(xiang)下移動(dong),使閥(fa)(fa)(fa)(fa)門(men)關閉。 ATOS電磁閥特點:在零(ling)壓(ya)差或真空、高壓(ya)時(shi)亦能可*動作(zuo),但(dan)功率較大,要求必須水(shui)平安裝。 3)先導式(shi)電磁閥(fa): ATOS電磁閥(fa)原理:通電時,電磁力(li)(li)(li)把(ba)先(xian)(xian)導孔打開,上(shang)腔(qiang)室壓(ya)力(li)(li)(li)迅速下降,在關(guan) 閉(bi)(bi)(bi)件(jian)周圍(wei)形(xing)成上(shang)低下高的(de)壓(ya)差(cha),流體壓(ya)力(li)(li)(li)推(tui)動(dong)(dong)關(guan)閉(bi)(bi)(bi)件(jian)向(xiang)上(shang)移(yi)動(dong)(dong),閥(fa)門打開;斷(duan)電時,彈(dan)簧力(li)(li)(li)把(ba)先(xian)(xian)導孔關(guan)閉(bi)(bi)(bi),入(ru)口壓(ya)力(li)(li)(li)通過旁通孔迅速腔(qiang)室在關(guan)閥(fa)件(jian)周圍(wei)形(xing)成下低上(shang)高的(de)壓(ya)差(cha),流體壓(ya)力(li)(li)(li)推(tui)動(dong)(dong)關(guan)閉(bi)(bi)(bi)件(jian)向(xiang)下移(yi)動(dong)(dong),關(guan)閉(bi)(bi)(bi)閥(fa)門。 ATOS電磁閥(fa)特點:流體壓力范圍上限較高,可任(ren)意安裝(需定制)但必須滿足(zu)流體壓差條件。 2、電磁(ci)閥從(cong)閥結(jie)(jie)構和(he)材料上的不同與(yu)原理上的區(qu)別,分(fen)為六(liu)個(ge)分(fen)支小類(lei):直(zhi)動(dong)膜(mo)片(pian)結(jie)(jie)構、分(fen)步直(zhi)動(dong)膜(mo)片(pian)結(jie)(jie)構、先(xian)(xian)導膜(mo)片(pian)結(jie)(jie)構、直(zhi)動(dong)活塞(sai)結(jie)(jie)構、分(fen)步直(zhi)動(dong)活塞(sai)結(jie)(jie)構、先(xian)(xian)導活塞(sai)結(jie)(jie)構。 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)按照功能分類:水用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、制(zhi)冷(leng)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、氣體(ti)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液體(ti)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、脈沖電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、液壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、油用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、直(zhi)流電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、高(gao)壓電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)、防爆(bao)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)等。 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 意大利阿托斯電磁閥DHU-0631/2-X 24DC? |
