一、電動蝶閥是什么
隨著電(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)門(men)的(de)發展,國內外有很多知名閥(fa)(fa)門(men)企(qi)業(ye)生產電(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)門(men),電(dian)(dian)(dian)動(dong)(dong)(dong)蝶閥(fa)(fa)是(shi)工(gong)業(ye)自動(dong)(dong)(dong)化控制領域中的(de)重(zhong)要執行單(dan)元,它屬于電(dian)(dian)(dian)動(dong)(dong)(dong)閥(fa)(fa)門(men)和電(dian)(dian)(dian)動(dong)(dong)(dong)調節閥(fa)(fa)中的(de)一(yi)個(ge)品種。
電(dian)動(dong)蝶閥廣泛用于(yu)紡(fang)織、電(dian)站、石油化工(gong)(gong)、供熱制(zhi)冷、制(zhi)藥、造(zao)船(chuan)(chuan)、冶金、輕工(gong)(gong)、環(huan)保(bao)等領域。完整的手(shou)動(dong)控制(zhi)裝置,電(dian)動(dong)或氣動(dong)傳動(dong)裝置,可以滿足不(bu)同工(gong)(gong)況具體條件(jian)。符合(he)最嚴(yan)格(ge)的質量要求,能夠(gou)非常(chang)持久的應用,特別是在冶金鋼鐵,船(chuan)(chuan)舶行業,有著非常(chang)高的知名度。
二、電動蝶閥的作用有哪些
電動(dong)(dong)蝶閥(fa)屬于(yu)(yu)電動(dong)(dong)閥(fa)門和(he)(he)電動(dong)(dong)調節閥(fa)中的一個品種。可(ke)用(yong)作管道系統(tong)的切(qie)斷閥(fa),控制閥(fa)和(he)(he)止回(hui)閥(fa)。附帶手動(dong)(dong)控制裝置,一旦出(chu)現電源(yuan)故障,可(ke)以(yi)臨時用(yong)手動(dong)(dong)操(cao)作,不至于(yu)(yu)影響使用(yong)。
常用的電動蝶閥有對夾式電動(dong)蝶(die)閥(fa)和法蘭式電動(dong)蝶(die)閥(fa)兩種。
三、電動蝶閥的工作原理是什么
電動蝶閥的工作電源(yuan)通常有(you):AC220V,AC380V等(deng)。輸入信號:4~20mA、0~10v等(deng)弱(ruo)電信號。
工作(zuo)原理是由調節型電(dian)動(dong)(dong)執(zhi)行(xing)機構和閥桿連(lian)接調試好以(yi)后,以(yi)電(dian)能作(zuo)為驅(qu)動(dong)(dong)力來(lai)驅(qu)動(dong)(dong)硬密(mi)封(feng)蝶(die)閥閥板,作(zuo)0~90°部分回(hui)轉運(yun)動(dong)(dong)。接收(shou)工業自動(dong)(dong)化控(kong)制(zhi)系(xi)統的4~20mA信號來(lai)精(jing)確控(kong)制(zhi)。
