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(fa)從原理上分為三大類: 1)ATOS直動式電磁(ci)閥: ATOS電(dian)磁(ci)閥(fa)(fa)原理:通(tong)電(dian)時,電(dian)磁(ci)線圈產生電(dian)磁(ci)力把(ba)關閉(bi)(bi)件從(cong)閥(fa)(fa)座上提起,閥(fa)(fa)門打開;斷(duan)電(dian)時,電(dian)磁(ci)力消失,彈簧把(ba)關閉(bi)(bi)件壓(ya)在閥(fa)(fa)座上,閥(fa)(fa)門關閉(bi)(bi)。 ATOS電(dian)磁閥特(te)點:在(zai)真空、負壓(ya)、零壓(ya)時能(neng)正常工作,但通徑一般不超(chao)過25mm。 2)分步直動式電磁閥: ATOS電磁(ci)閥(fa)(fa)原理:它是一種直動(dong)和先導式(shi)相結合的原理,當入口(kou)與(yu)出口(kou)沒有壓(ya)差時(shi),通電后,電磁(ci)力(li)(li)直接把先導小閥(fa)(fa)和主(zhu)閥(fa)(fa)關(guan)閉(bi)件依次向上(shang)提起,閥(fa)(fa)門打開。當入口(kou)與(yu)出口(kou)達(da)到啟(qi)動(dong)壓(ya)差時(shi),通電后,電磁(ci)力(li)(li)先導小閥(fa)(fa),主(zhu)閥(fa)(fa)下腔壓(ya)力(li)(li)上(shang)升,上(shang)腔壓(ya)力(li)(li)下降,從而(er)利(li)用壓(ya)差把主(zhu)閥(fa)(fa)向上(shang)推(tui)開;斷(duan)電時(shi),先導閥(fa)(fa)利(li)用彈簧(huang)力(li)(li)或(huo)介質壓(ya)力(li)(li)推(tui)動(dong)關(guan)閉(bi)件,向下移(yi)動(dong),使閥(fa)(fa)門關(guan)閉(bi)。 ATOS電(dian)磁閥特點(dian):在(zai)零(ling)壓(ya)差或真空(kong)、高壓(ya)時亦能可*動作,但功率較大,要(yao)求必須水(shui)平安裝。 3)先導式電磁閥: ATOS電磁閥(fa)原理(li):通電時(shi),電磁力把(ba)先導(dao)孔(kong)(kong)(kong)打開,上腔(qiang)室(shi)壓(ya)力迅速(su)(su)下(xia)(xia)降,在關 閉(bi)(bi)(bi)件(jian)周(zhou)圍(wei)(wei)形成(cheng)上低下(xia)(xia)高的(de)壓(ya)差(cha),流(liu)體壓(ya)力推(tui)動(dong)(dong)關閉(bi)(bi)(bi)件(jian)向(xiang)上移動(dong)(dong),閥(fa)門打開;斷電時(shi),彈(dan)簧力把(ba)先導(dao)孔(kong)(kong)(kong)關閉(bi)(bi)(bi),入口(kou)壓(ya)力通過旁通孔(kong)(kong)(kong)迅速(su)(su)腔(qiang)室(shi)在關閥(fa)件(jian)周(zhou)圍(wei)(wei)形成(cheng)下(xia)(xia)低上高的(de)壓(ya)差(cha),流(liu)體壓(ya)力推(tui)動(dong)(dong)關閉(bi)(bi)(bi)件(jian)向(xiang)下(xia)(xia)移動(dong)(dong),關閉(bi)(bi)(bi)閥(fa)門。 ATOS電磁(ci)閥特點:流(liu)(liu)體壓力范圍上(shang)限較高,可任意(yi)安(an)裝(需(xu)定制)但必須滿足流(liu)(liu)體壓差條(tiao)件。 2、電磁閥(fa)從閥(fa)結(jie)(jie)(jie)構和材料(liao)上的不同與原理上的區別,分(fen)為(wei)六個分(fen)支小類(lei):直(zhi)動(dong)膜(mo)片(pian)結(jie)(jie)(jie)構、分(fen)步直(zhi)動(dong)膜(mo)片(pian)結(jie)(jie)(jie)構、先(xian)導膜(mo)片(pian)結(jie)(jie)(jie)構、直(zhi)動(dong)活(huo)塞(sai)(sai)結(jie)(jie)(jie)構、分(fen)步直(zhi)動(dong)活(huo)塞(sai)(sai)結(jie)(jie)(jie)構、先(xian)導活(huo)塞(sai)(sai)結(jie)(jie)(jie)構。 3、電(dian)(dian)(dian)(dian)(dian)磁閥(fa)按照功能分類:水用電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、蒸汽(qi)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、制(zhi)冷電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、低溫電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、燃氣電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、消防電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、氨用電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、氣體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、液體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、微型電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、脈沖電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、液壓電(dian)(dian)(dian)(dian)(dian)磁閥(fa) 常開電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、油用電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、直(zhi)流電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、高壓電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、防爆電(dian)(dian)(dian)(dian)(dian)磁閥(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 意大利ATOS電磁閥DHU-0631/2/A-X 24DC? |
