原理(li):它是(shi)種直動和導(dao)式相(xiang)結合(he)的原理(li),當入(ru)口(kou)與出口(kou)沒有壓(ya)差時(shi)(shi),通(tong)電(dian)后,電(dian)磁力(li)(li)直接把導(dao)小閥(fa)和主(zhu)閥(fa)關(guan)閉件依(yi)次向上提起,閥(fa)門打開。當入(ru)口(kou)與出口(kou)達到啟動壓(ya)差時(shi)(shi),通(tong)電(dian)后,電(dian)磁力(li)(li)導(dao)小閥(fa),主(zhu)閥(fa)下腔壓(ya)力(li)(li)上升,上腔壓(ya)力(li)(li)下降,從而利(li)用壓(ya)差把主(zhu)閥(fa)向上推開;斷電(dian)時(shi)(shi),導(dao)閥(fa)利(li)用彈簧力(li)(li)或介質壓(ya)力(li)(li)推動關(guan)閉件,向下移動,使閥(fa)門關(guan)閉。特(te)點:在(zai)零壓(ya)差或真空、高壓(ya)時(shi)(shi)亦能(neng)可*動作,但功率較大,要(yao)求必須(xu)水平安裝。
調(diao)(diao)節精度(du)(du)(du)受限(xian),適(shi)用(yong)(yong)介(jie)質受限(xian)。電磁閥通常只有開關(guan)兩種(zhong)狀態(tai),閥芯只能處(chu)于兩個極限(xian)位置,不能連續調(diao)(diao)節,(力圖突破(po)的(de)新構思不少,但還都處(chu)于試驗試用(yong)(yong)階段)所以調(diao)(diao)節精度(du)(du)(du)還受到定限(xian)制。電磁閥對(dui)介(jie)質潔凈度(du)(du)(du)有較高要(yao)求,含(han)顆粒狀的(de)介(jie)質不能適(shi)用(yong)(yong),如屬(shu)雜質須濾去。另外,粘稠狀介(jie)質不能適(shi)用(yong)(yong),而且,特定的(de)產品適(shi)用(yong)(yong)的(de)介(jie)質粘度(du)(du)(du)范圍相對(dui)較窄。
型號多樣,用途(tu)廣泛。電(dian)磁閥(fa)(fa)雖(sui)有(you)天(tian)不(bu)(bu)足,優(you)點仍十分突出,所以就(jiu)(jiu)(jiu)設 1[1]計成(cheng)多種(zhong)多樣的(de)(de)產品,滿足各種(zhong)不(bu)(bu)同的(de)(de)需(xu)求,用途(tu)極為廣泛。電(dian)磁閥(fa)(fa)技術的(de)(de)進(jin)步(bu)也都是(shi)圍繞著如(ru)何克服天(tian)不(bu)(bu)足,如(ru)何更好(hao)地發揮固(gu)有(you)優(you)勢而展開(kai)。FESTO電(dian)磁閥(fa)(fa)是(shi)用來(lai)控制(zhi)(zhi)(zhi)流(liu)體(ti)方向的(de)(de)自動(dong)化(hua)基(ji)礎元件,屬于(yu)執行器;通(tong)(tong)(tong)(tong)常用于(yu)機械(xie)控制(zhi)(zhi)(zhi)和工業閥(fa)(fa)門上(shang)面,對(dui)介質方向進(jin)行控制(zhi)(zhi)(zhi),從而達(da)到對(dui)閥(fa)(fa)門開(kai)關的(de)(de)控制(zhi)(zhi)(zhi)。工作原理電(dian)磁閥(fa)(fa)里有(you)密閉的(de)(de)腔,在(zai)不(bu)(bu)同位置(zhi)開(kai)有(you)通(tong)(tong)(tong)(tong)孔(kong),每個孔(kong)都通(tong)(tong)(tong)(tong)向不(bu)(bu)同的(de)(de)油(you)(you)(you)管(guan),腔中間是(shi)閥(fa)(fa),兩(liang)面是(shi)兩(liang)塊電(dian)磁鐵,哪面的(de)(de)磁鐵線(xian)圈通(tong)(tong)(tong)(tong)電(dian)閥(fa)(fa)體(ti)就(jiu)(jiu)(jiu)會(hui)(hui)被吸引到哪邊,通(tong)(tong)(tong)(tong)過(guo)控制(zhi)(zhi)(zhi)閥(fa)(fa)體(ti)的(de)(de)移動(dong)來(lai)擋住(zhu)或漏出不(bu)(bu)同的(de)(de)排(pai)油(you)(you)(you)的(de)(de)孔(kong),而進(jin)油(you)(you)(you)孔(kong)是(shi)常開(kai)的(de)(de),液壓(ya)油(you)(you)(you)就(jiu)(jiu)(jiu)會(hui)(hui)進(jin)入(ru)不(bu)(bu)同的(de)(de)排(pai)油(you)(you)(you)管(guan),然后通(tong)(tong)(tong)(tong)過(guo)油(you)(you)(you)的(de)(de)壓(ya)力來(lai)推動(dong)油(you)(you)(you)缸的(de)(de)活塞(sai)(sai)(sai),活塞(sai)(sai)(sai)又帶(dai)動(dong)活塞(sai)(sai)(sai)桿(gan),活塞(sai)(sai)(sai)桿(gan)帶(dai)動(dong)機械(xie)裝置(zhi)動(dong)。這(zhe)樣通(tong)(tong)(tong)(tong)過(guo)控制(zhi)(zhi)(zhi)電(dian)磁鐵的(de)(de)電(dian)流(liu)通(tong)(tong)(tong)(tong)斷就(jiu)(jiu)(jiu)控制(zhi)(zhi)(zhi)了機械(xie)運動(dong)。
