電磁閥是用(yong)(yong)來控制(zhi)流(liu)體的方向的自動化基礎(chu)元件，屬于執行器；通常用(yong)(yong)于機械控制(zhi)和工業(ye)閥門上面(mian)，對介質方向進行控制(zhi)，從而(er)達到對閥門開(kai)(kai)(kai)關的(de)(de)控(kong)制(zhi)(zhi)(zhi)(zhi)。電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)里有(you)(you)密(mi)閉的(de)(de)腔，在不同(tong)位置開(kai)(kai)(kai)有(you)(you)通(tong)(tong)(tong)(tong)孔(kong)，每個孔(kong)都(dou)通(tong)(tong)(tong)(tong)向(xiang)不同(tong)的(de)(de)油(you)(you)管(guan)，腔中間是(shi)(shi)(shi)閥(fa)(fa)(fa)(fa)，兩面是(shi)(shi)(shi)兩塊電(dian)(dian)磁(ci)(ci)(ci)(ci)鐵(tie)，哪面的(de)(de)磁(ci)(ci)(ci)(ci)鐵(tie)線(xian)圈通(tong)(tong)(tong)(tong)電(dian)(dian)閥(fa)(fa)(fa)(fa)體就會(hui)被吸引到哪邊，通(tong)(tong)(tong)(tong)過控(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)體的(de)(de)移動來(lai)檔住或漏(lou)出不同(tong)的(de)(de)排油(you)(you)的(de)(de)孔(kong)，而進油(you)(you)孔(kong)是(shi)(shi)(shi)常開(kai)(kai)(kai)的(de)(de)，液(ye)壓油(you)(you)就會(hui)進入不同(tong)的(de)(de)排油(you)(you)管(guan)，然后通(tong)(tong)(tong)(tong)過油(you)(you)的(de)(de)壓力(li)來(lai)推動油(you)(you)缸的(de)(de)活塞，活塞又帶(dai)動活塞桿(gan)(gan)，活塞桿(gan)(gan)帶(dai)動機械裝置動。這樣通(tong)(tong)(tong)(tong)過控(kong)制(zhi)(zhi)(zhi)(zhi)電(dian)(dian)磁(ci)(ci)(ci)(ci)鐵(tie)的(de)(de)電(dian)(dian)流就控(kong)制(zhi)(zhi)(zhi)(zhi)了機械運(yun)動。唯(wei)有(you)(you)電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)是(shi)(shi)(shi)用(yong)電(dian)(dian)磁(ci)(ci)(ci)(ci)力(li)作用(yong)于(yu)密(mi)封在電(dian)(dian)動調(diao)節閥(fa)(fa)(fa)(fa)隔磁(ci)(ci)(ci)(ci)套管(guan)內(nei)的(de)(de)鐵(tie)芯完成(cheng)，不存在動密(mi)封，所以(yi)外漏(lou)易堵絕(jue)。電(dian)(dian)動閥(fa)(fa)(fa)(fa)力(li)矩控(kong)制(zhi)(zhi)(zhi)(zhi)不易，容(rong)(rong)易產生內(nei)漏(lou)，甚至拉斷閥(fa)(fa)(fa)(fa)桿(gan)(gan)頭部；電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)(de)結(jie)構型(xing)式容(rong)(rong)易控(kong)制(zhi)(zhi)(zhi)(zhi)內(nei)泄漏(lou)，直至降為零。所以(yi)，電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)使用(yong)特(te)別安全，尤其適(shi)用(yong)于(yu)腐蝕性、有(you)(you)毒或高低(di)溫的(de)(de)介質。電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)本身結(jie)構簡單，價(jia)格也(ye)低(di)，比起(qi)調(diao)節閥(fa)(fa)(fa)(fa)等(deng)其它種類執行器易于(yu)安裝維護。更顯著的(de)(de)是(shi)(shi)(shi)所組成(cheng)的(de)(de)自(zi)控(kong)系統簡單得(de)多，價(jia)格要低(di)得(de)多。由于(yu)電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)是(shi)(shi)(shi)開(kai)(kai)(kai)關信號控(kong)制(zhi)(zhi)(zhi)(zhi)，與工控(kong)計算(suan)機連接(jie)十分方便。在當(dang)今電(dian)(dian)腦普及，價(jia)格大幅下降的(de)(de)時代，電(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)(de)優勢就更加明(ming)顯。 |
