美(mei)國PARKER派克電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)眾多(duo)(duo)領(ling)域:石油化工,橡膠,汽車,火車,電(dian)(dian)(dian)(dian)(dian)力(li),液壓(ya)氣動,食(shi)品機(ji)械(xie),機(ji)器人,控(kong)(kong)(kong)制閥(fa)(fa)(fa)(fa)門等。PARKER電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)作(zuo)為過(guo)程控(kong)(kong)(kong)制系統(tong)的(de)(de)(de)(de)(de)(de)(de)執(zhi)行(xing)元件之一,其安全性和可(ke)靠(kao)(kao)性早已為廣大客戶(hu)所*,為更(geng)(geng)好(hao)地服務 于這(zhe)一領(ling)域的(de)(de)(de)(de)(de)(de)(de)石油開采,煉(lian)油,天然氣,石化電(dian)(dian)(dian)(dian)(dian)廠,水處理等行(xing)業應用的(de)(de)(de)(de)(de)(de)(de)多(duo)(duo)樣性和更(geng)(geng)可(ke)靠(kao)(kao)性的(de)(de)(de)(de)(de)(de)(de)要(yao)求,及方便(bian)用戶(hu)和設計院的(de)(de)(de)(de)(de)(de)(de)選型(xing)。唯有電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)是用電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)力(li)作(zuo)用于密封在電(dian)(dian)(dian)(dian)(dian)動調節閥(fa)(fa)(fa)(fa)隔磁(ci)(ci)套(tao)管內的(de)(de)(de)(de)(de)(de)(de)鐵(tie)芯完成(cheng),不(bu)存在動密封,所以(yi)外漏易(yi)(yi)堵絕(jue)。電(dian)(dian)(dian)(dian)(dian)動閥(fa)(fa)(fa)(fa)力(li)矩控(kong)(kong)(kong)制不(bu)易(yi)(yi),容易(yi)(yi)產生內漏,甚(shen)至(zhi)拉(la)斷(duan)閥(fa)(fa)(fa)(fa)桿(gan)頭部;電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)(de)(de)(de)(de)(de)(de)結構型(xing)式(shi)容易(yi)(yi)控(kong)(kong)(kong)制內泄漏,直(zhi)至(zhi)降為零。所以(yi),電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)使用特別安全,尤其適用于腐蝕性、有毒或高低溫(wen)的(de)(de)(de)(de)(de)(de)(de)介質。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)本身結構簡單,價(jia)(jia)格也低,比起調節閥(fa)(fa)(fa)(fa)等其它種類執(zhi)行(xing)器易(yi)(yi)于安裝維護。更(geng)(geng)顯著(zhu)的(de)(de)(de)(de)(de)(de)(de)是所組(zu)成(cheng)的(de)(de)(de)(de)(de)(de)(de)自控(kong)(kong)(kong)系統(tong)簡單得多(duo)(duo),價(jia)(jia)格要(yao)低得多(duo)(duo)。由于電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)是開關信號(hao)控(kong)(kong)(kong)制,與工控(kong)(kong)(kong)計算機(ji)連接十分(fen)方便(bian)。在當今電(dian)(dian)(dian)(dian)(dian)腦(nao)普及,價(jia)(jia)格大幅(fu)下降的(de)(de)(de)(de)(de)(de)(de)時代,電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)(de)(de)(de)(de)(de)(de)優勢就(jiu)更(geng)(geng)加明顯。
PARKER電磁閥閥門開關的工作原理,當出入口無壓強差或壓強差較小還不足以推動閥門運動時,利用電磁力的作用打開閥門(同直動式派克PARKER電磁閥);當出入口壓強差可推動閥門運動時,利用壓強的作用打開閥門(同先導式派克PARKER電磁閥);斷電后,既無壓強差也無電磁力時,閥門在彈簧作用下關閉。
綜上所述,派克PARKER電磁閥工作原理是通過控制電磁線圈通斷電來控制閥門開關,進而控制機械裝置的運動,而三種派克PARKER電磁閥的工作原理不同就在于其電磁線圈通斷電導致閥門開關的方式不同。
