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(fa)從原理上分為三大類: 1)ATOS直動式電磁閥(fa): ATOS電磁(ci)閥(fa)原(yuan)理:通電時,電磁(ci)線圈產(chan)生電磁(ci)力把關閉(bi)件從閥(fa)座上提起,閥(fa)門打開;斷電時,電磁(ci)力消(xiao)失,彈簧把關閉(bi)件壓在閥(fa)座上,閥(fa)門關閉(bi)。 ATOS電磁閥特點:在真空、負壓、零壓時(shi)能正常工作,但(dan)通徑一般不超過25mm。 2)分(fen)步直動(dong)式電磁閥: ATOS電(dian)(dian)磁閥(fa)(fa)原(yuan)(yuan)理(li):它是一種直動和(he)先導(dao)式相結(jie)合的原(yuan)(yuan)理(li),當入口(kou)(kou)與出(chu)(chu)口(kou)(kou)沒有壓(ya)(ya)(ya)差(cha)(cha)時,通電(dian)(dian)后,電(dian)(dian)磁力(li)直接把先導(dao)小閥(fa)(fa)和(he)主閥(fa)(fa)關閉件依(yi)次向(xiang)上(shang)提起,閥(fa)(fa)門打開。當入口(kou)(kou)與出(chu)(chu)口(kou)(kou)達到啟動壓(ya)(ya)(ya)差(cha)(cha)時,通電(dian)(dian)后,電(dian)(dian)磁力(li)先導(dao)小閥(fa)(fa),主閥(fa)(fa)下(xia)腔(qiang)壓(ya)(ya)(ya)力(li)上(shang)升,上(shang)腔(qiang)壓(ya)(ya)(ya)力(li)下(xia)降,從而利用壓(ya)(ya)(ya)差(cha)(cha)把主閥(fa)(fa)向(xiang)上(shang)推開;斷電(dian)(dian)時,先導(dao)閥(fa)(fa)利用彈(dan)簧(huang)力(li)或介質(zhi)壓(ya)(ya)(ya)力(li)推動關閉件,向(xiang)下(xia)移動,使閥(fa)(fa)門關閉。 ATOS電磁閥(fa)特點:在零壓差或真空、高壓時亦能可*動作,但功率較大(da),要(yao)求必(bi)須水(shui)平安(an)裝。 3)先(xian)導式(shi)電磁閥: ATOS電(dian)(dian)磁閥(fa)原理:通電(dian)(dian)時,電(dian)(dian)磁力(li)把(ba)先(xian)導孔打(da)開,上(shang)腔(qiang)室壓(ya)力(li)迅(xun)(xun)速(su)下降,在(zai)關(guan) 閉件周圍(wei)形成上(shang)低下高(gao)的(de)壓(ya)差,流(liu)體壓(ya)力(li)推(tui)動關(guan)閉件向(xiang)上(shang)移動,閥(fa)門打(da)開;斷電(dian)(dian)時,彈(dan)簧(huang)力(li)把(ba)先(xian)導孔關(guan)閉,入口壓(ya)力(li)通過旁(pang)通孔迅(xun)(xun)速(su)腔(qiang)室在(zai)關(guan)閥(fa)件周圍(wei)形成下低上(shang)高(gao)的(de)壓(ya)差,流(liu)體壓(ya)力(li)推(tui)動關(guan)閉件向(xiang)下移動,關(guan)閉閥(fa)門。 ATOS電磁(ci)閥特點:流(liu)體(ti)壓(ya)力(li)范圍(wei)上限較高,可(ke)任意安裝(需定制)但必須滿足流(liu)體(ti)壓(ya)差條件。 2、電磁閥(fa)從閥(fa)結(jie)構(gou)和(he)材料上(shang)的(de)不同與原(yuan)理(li)上(shang)的(de)區別,分為六個分支(zhi)小類(lei):直動膜片(pian)結(jie)構(gou)、分步直動膜片(pian)結(jie)構(gou)、先導膜片(pian)結(jie)構(gou)、直動活塞結(jie)構(gou)、分步直動活塞結(jie)構(gou)、先導活塞結(jie)構(gou)。 3、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)按照(zhao)功能分類:水用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、制冷(leng)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氨用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氣體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液體電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、微(wei)型電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、脈沖(chong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液壓(ya)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、油用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、高壓(ya)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、防爆電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(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 |
