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電磁閥(fa)從原理上分為(wei)三大類: 1)ATOS直動式電磁閥(fa): ATOS電(dian)(dian)(dian)磁閥(fa)原理:通(tong)電(dian)(dian)(dian)時,電(dian)(dian)(dian)磁線圈(quan)產生電(dian)(dian)(dian)磁力(li)把關閉件從閥(fa)座上提起,閥(fa)門打開;斷(duan)電(dian)(dian)(dian)時,電(dian)(dian)(dian)磁力(li)消失,彈簧把關閉件壓在閥(fa)座上,閥(fa)門關閉。 ATOS電磁閥(fa)特點(dian):在真空(kong)、負壓(ya)(ya)、零(ling)壓(ya)(ya)時(shi)能正常(chang)工作(zuo),但通徑一般不超過25mm。 2)分步(bu)直動(dong)式電磁閥: ATOS電(dian)磁閥(fa)(fa)原(yuan)理(li):它是一(yi)種直動和先(xian)導(dao)式相(xiang)結合的原(yuan)理(li),當入(ru)口(kou)與(yu)出(chu)口(kou)沒有壓(ya)差時(shi),通(tong)電(dian)后,電(dian)磁力(li)(li)直接(jie)把先(xian)導(dao)小閥(fa)(fa)和主(zhu)閥(fa)(fa)關閉件(jian)依次向(xiang)上(shang)提起,閥(fa)(fa)門打開(kai)。當入(ru)口(kou)與(yu)出(chu)口(kou)達到啟動壓(ya)差時(shi),通(tong)電(dian)后,電(dian)磁力(li)(li)先(xian)導(dao)小閥(fa)(fa),主(zhu)閥(fa)(fa)下(xia)腔壓(ya)力(li)(li)上(shang)升,上(shang)腔壓(ya)力(li)(li)下(xia)降,從(cong)而(er)利用壓(ya)差把主(zhu)閥(fa)(fa)向(xiang)上(shang)推開(kai);斷電(dian)時(shi),先(xian)導(dao)閥(fa)(fa)利用彈簧力(li)(li)或介(jie)質壓(ya)力(li)(li)推動關閉件(jian),向(xiang)下(xia)移動,使(shi)閥(fa)(fa)門關閉。 ATOS電磁閥特點:在(zai)零壓差(cha)或真(zhen)空、高壓時亦(yi)能可(ke)*動作,但功率較大,要求必須(xu)水平(ping)安裝。 3)先導式電磁閥: ATOS電(dian)磁(ci)(ci)閥(fa)(fa)原理:通電(dian)時,電(dian)磁(ci)(ci)力(li)(li)(li)把先導孔打(da)開(kai),上(shang)腔室(shi)(shi)壓(ya)(ya)力(li)(li)(li)迅(xun)速下(xia)降,在關(guan)(guan) 閉(bi)件(jian)(jian)周(zhou)圍形成上(shang)低下(xia)高的(de)壓(ya)(ya)差,流體壓(ya)(ya)力(li)(li)(li)推動(dong)關(guan)(guan)閉(bi)件(jian)(jian)向上(shang)移動(dong),閥(fa)(fa)門打(da)開(kai);斷電(dian)時,彈簧力(li)(li)(li)把先導孔關(guan)(guan)閉(bi),入口(kou)壓(ya)(ya)力(li)(li)(li)通過旁通孔迅(xun)速腔室(shi)(shi)在關(guan)(guan)閥(fa)(fa)件(jian)(jian)周(zhou)圍形成下(xia)低上(shang)高的(de)壓(ya)(ya)差,流體壓(ya)(ya)力(li)(li)(li)推動(dong)關(guan)(guan)閉(bi)件(jian)(jian)向下(xia)移動(dong),關(guan)(guan)閉(bi)閥(fa)(fa)門。 ATOS電(dian)磁閥特點:流體(ti)壓(ya)(ya)力范圍(wei)上(shang)限較高,可任意安裝(需定(ding)制)但(dan)必須滿足(zu)流體(ti)壓(ya)(ya)差條件。 2、電磁閥從閥結(jie)(jie)構(gou)(gou)和(he)材料上(shang)的不同與原理上(shang)的區別,分為六個(ge)分支小類:直(zhi)動(dong)(dong)膜(mo)片(pian)結(jie)(jie)構(gou)(gou)、分步(bu)(bu)直(zhi)動(dong)(dong)膜(mo)片(pian)結(jie)(jie)構(gou)(gou)、先導(dao)膜(mo)片(pian)結(jie)(jie)構(gou)(gou)、直(zhi)動(dong)(dong)活(huo)塞(sai)結(jie)(jie)構(gou)(gou)、分步(bu)(bu)直(zhi)動(dong)(dong)活(huo)塞(sai)結(jie)(jie)構(gou)(gou)、先導(dao)活(huo)塞(sai)結(jie)(jie)構(gou)(gou)。 3、電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)按照功能分類:水(shui)用(yong)電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、蒸汽(qi)電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、制冷電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、低溫電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、燃氣電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、消(xiao)防電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、氨用(yong)電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、氣體電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、液體電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、微(wei)型電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、脈沖電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、液壓電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa) 常開(kai)電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、油用(yong)電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、直(zhi)流電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、高壓電(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)、防爆(bao)電(dian)(dian)磁(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 意大利ATOS電磁閥DHU-0631/2-X 24DC? |
