ASCO二位五通防(fang)爆(bao)型(xing)電磁閥(fa)尺寸圖
二(er)位五通(tong)電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)是(shi)用(yong)來控制(zhi)流(liu)體的(de)自動(dong)化基礎元件,屬(shu)于(yu)執行器;并(bing)不(bu)限于(yu)液(ye)壓(ya),氣動(dong)。電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)用(yong)于(yu)控制(zhi)液(ye)壓(ya)流(liu)動(dong)方向,工廠的(de)機(ji)械(xie)裝(zhuang)置一般都(dou)由液(ye)壓(ya)缸控制(zhi),所以(yi)就(jiu)會用(yong)到電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)。 電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)的(de)工作(zuo)原理(li),電(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)里有密閉的(de)腔,在的(de)不(bu)同位置開(kai)有通(tong)孔(kong),每個(ge)孔(kong)都(dou)通(tong)向不(bu)同的(de)油(you)(you)管(guan)(guan),腔中間是(shi)閥(fa),兩(liang)面是(shi)兩(liang)塊電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵,哪面的(de)磁(ci)(ci)(ci)鐵線圈通(tong)電(dian)(dian)(dian)閥(fa)體就(jiu)會被吸引到哪邊,通(tong)過(guo)(guo)控制(zhi)閥(fa)體的(de)移動(dong)來檔住或漏出不(bu)同的(de)排油(you)(you)的(de)孔(kong),而(er)進(jin)(jin)油(you)(you)孔(kong)是(shi)常開(kai)的(de),液(ye)壓(ya)油(you)(you)就(jiu)會進(jin)(jin)入不(bu)同的(de)排油(you)(you)管(guan)(guan),然(ran)后通(tong)過(guo)(guo)油(you)(you)的(de)壓(ya)力來推動(dong)油(you)(you)缸的(de)活塞,活塞又帶動(dong)活塞桿(gan),活塞桿(gan)帶動(dong)機(ji)械(xie)裝(zhuang)置運(yun)動(dong)。這樣通(tong)過(guo)(guo)控制(zhi)電(dian)(dian)(dian)磁(ci)(ci)(ci)鐵的(de)電(dian)(dian)(dian)流(liu)就(jiu)控制(zhi)了機(ji)械(xie)運(yun)動(dong)。
在一些特(te)殊(shu)的(de)工(gong)作場(chang)所,和(he)用(yong)在特(te)殊(shu)介質(zhi)的(de)電(dian)(dian)磁閥,例如有酸(suan)堿性介質(zhi)的(de)工(gong)作環境,黃銅(tong)和(he)不銹(xiu)鋼材質(zhi)的(de)電(dian)(dian)磁閥產品均容易被腐(fu)蝕(shi),所以用(yong)特(te)殊(shu)材質(zhi)(工(gong)程塑料PVC、 CPVC、UPVC、ABS或聚四氟等)做成的(de)塑料電(dian)(dian)磁閥在耐腐(fu)蝕(shi)性能上特(te)別(bie)優秀,
流體壓(ya)力范圍上限較(jiao)高,可任意安裝(需定制)但(dan)必須滿足流體壓(ya)差條(tiao)件。
開關式電磁閥,即(ji)起開關作用,當有電流流過時,電磁閥控(kong)制線路(lu)或油路(lu)通斷。
比例式電磁閥,即根(gen)據輸(shu)入的電流(liu)大小不(bu)同,輸(shu)出(chu)的壓力不(bu)同,當改變(bian)輸(shu)入電流(liu)時,即可(ke)改變(bian)電磁閥輸(shu)出(chu)壓力,多用(yong)于液(ye)壓系統。
特點:在零壓差或真空、高壓時亦能可*動作(zuo),但功率較(jiao)大,要求必(bi)須水平(ping)安裝(zhuang)。
通(tong)(tong)電(dian)時(shi)(shi),電(dian)磁力(li)把(ba)先導(dao)孔(kong)打開,上腔室(shi)壓(ya)(ya)力(li)迅速(su)下降,在關(guan) 閉(bi)(bi)件周圍形(xing)成上低下高的壓(ya)(ya)差,流體壓(ya)(ya)力(li)推(tui)動(dong)關(guan)閉(bi)(bi)件向上移動(dong),閥門打開;斷電(dian)時(shi)(shi),彈(dan)簧力(li)把(ba)先導(dao)孔(kong)關(guan)閉(bi)(bi),入(ru)口壓(ya)(ya)力(li)通(tong)(tong)過旁通(tong)(tong)孔(kong)迅速(su)腔室(shi)在關(guan)閥件周圍形(xing)成下低上高的壓(ya)(ya)差,流體壓(ya)(ya)力(li)推(tui)動(dong)關(guan)閉(bi)(bi)件向下移動(dong),關(guan)閉(bi)(bi)閥門。
