意大利ATOS電磁閥的工作原理 ATOS電(dian)磁閥(fa)(fa)里有密閉的腔,在不(bu)同位(wei)置開有通(tong)孔(kong),每個孔(kong)連接不(bu)同的油(you)管,腔中間是活(huo)(huo)塞(sai),兩(liang)面是兩(liang)塊電(dian)磁鐵(tie),哪(na)面的磁鐵(tie)線圈通(tong)電(dian)閥(fa)(fa)體(ti)就(jiu)會被吸(xi)引(yin)到哪(na)邊,通(tong)過(guo)(guo)控(kong)制閥(fa)(fa)體(ti)的移(yi)動來開啟或(huo)關(guan)閉不(bu)同的排油(you)孔(kong),而進油(you)孔(kong)是常(chang)開的,液(ye)壓(ya)(ya)油(you)就(jiu)會進入不(bu)同的排油(you)管,然后(hou)通(tong)過(guo)(guo)油(you)的壓(ya)(ya)力來推(tui)動油(you)缸的活(huo)(huo)塞(sai),活(huo)(huo)塞(sai)又帶(dai)動活(huo)(huo)塞(sai)桿(gan)(gan),活(huo)(huo)塞(sai)桿(gan)(gan)帶(dai)動機(ji)械裝置。這樣通(tong)過(guo)(guo)控(kong)制電(dian)磁鐵(tie)的電(dian)流通(tong)斷就(jiu)控(kong)制了機(ji)械運(yun)動。 ATOS電磁閥(fa)主要(yao)分(fen)類: 1、ATOS電磁閥從原理(li)上(shang)分(fen)為三大類: 1)直(zhi)動式電磁閥: ATOS電磁閥原理:通電時,電磁線圈產生電磁力把關閉件從閥座上提起,閥門打開;斷電時,電磁力消失,彈簧把關閉件壓在閥座上,閥門關閉。 ATOS電磁閥特點:在真空、負壓、零壓時能正常工作,但通徑一般不超過25mm。 2)分(fen)步直動式電磁閥: ATOS電(dian)磁閥(fa)(fa)(fa)原理:它是一種直(zhi)動(dong)和先(xian)(xian)導式相結合的原理,當入口與出口沒有壓(ya)差時,通(tong)電(dian)后,電(dian)磁力(li)直(zhi)接把先(xian)(xian)導小(xiao)閥(fa)(fa)(fa)和主閥(fa)(fa)(fa)關(guan)(guan)閉(bi)件(jian)依(yi)次(ci)向(xiang)上(shang)提起,閥(fa)(fa)(fa)門打開。當入口與出口達(da)到啟(qi)動(dong)壓(ya)差時,通(tong)電(dian)后,電(dian)磁力(li)先(xian)(xian)導小(xiao)閥(fa)(fa)(fa),主閥(fa)(fa)(fa)下腔壓(ya)力(li)上(shang)升,上(shang)腔壓(ya)力(li)下降,從而(er)利用壓(ya)差把主閥(fa)(fa)(fa)向(xiang)上(shang)推(tui)開;斷電(dian)時,先(xian)(xian)導閥(fa)(fa)(fa)利用彈(dan)簧力(li)或介質壓(ya)力(li)推(tui)動(dong)關(guan)(guan)閉(bi)件(jian),向(xiang)下移動(dong),使(shi)閥(fa)(fa)(fa)門關(guan)(guan)閉(bi)。 ATOS電磁閥(fa)特點:在(zai)零壓(ya)差或真空、高壓(ya)時(shi)亦能可*動作,但功率較大,要求必須(xu)水平安裝(zhuang)。 3)先(xian)導式電磁閥: ATOS電磁(ci)(ci)閥(fa)原理:通(tong)(tong)(tong)電時(shi),電磁(ci)(ci)力(li)(li)把先(xian)導孔(kong)(kong)打開(kai),上(shang)(shang)腔室壓力(li)(li)迅速下(xia)降,在(zai)關閉(bi)件(jian)周圍形成上(shang)(shang)低(di)(di)下(xia)高(gao)的壓差,流(liu)體壓力(li)(li)推(tui)動(dong)關閉(bi)件(jian)向上(shang)(shang)移動(dong),閥(fa)門打開(kai);斷(duan)電時(shi),彈簧力(li)(li)把先(xian)導孔(kong)(kong)關閉(bi),入(ru)口(kou)壓力(li)(li)通(tong)(tong)(tong)過旁通(tong)(tong)(tong)孔(kong)(kong)迅速腔室在(zai)關閥(fa)件(jian)周圍形成下(xia)低(di)(di)上(shang)(shang)高(gao)的壓差,流(liu)體壓力(li)(li)推(tui)動(dong)關閉(bi)件(jian)向下(xia)移動(dong),關閉(bi)閥(fa)門。 ATOS電磁(ci)閥特點: 流體(ti)壓(ya)力(li)范圍上限較高(gao),可任意安裝(zhuang)(需(xu)定制)但必須(xu)滿足流體(ti)壓(ya)差條(tiao)件。 意大利阿托斯ATOS電磁閥現貨: DHI-0713-X 230/50/60AC DHI-0713-X 24DC DHI-0713-X 24DC 23 /PE DHI-0714/WP-X 230/50/60AC DHI-0714/WP-X 230/50/60AC 23 /PE DHI-0714-X 230/50/60AC DHI-0714-X 24DC DHI-0715/FI/NC-X 24DC DHI-0715-X 24DC DHI-0716-X 24DC DHI-0717-X 24DC DHI-0718-X 230/50/60AC DHI-0718-X 24DC DHI-0750/2-X 24DC DHI-0751/2/FI/NC-X 24DC 23 DHI-0751/2/FI/NO-X 24DC 23 DHI-0751/2/WP-X 230/50/60AC DHI-0751/2/WP-X 230/50/60AC 23 /PE DHI-0751/2/WP-X 24DC DHI-0751/2-X 110/50/60AC 23 DHI-0751/2-X 230/50/60AC DHI-0751/2-X 24DC |
