    電動蝶閥分開關型和調理型兩種,具有構造簡單、流通才能大、適用范圍廣等特性,配銳博CHR、CHQ、381R、PSQ等電動執行器,能夠開關量控制,也能夠接納PLC、DCS等上位機的4-20mA或者1-5V控制信號,完成連續調理。電動蝶閥普遍適用于給排水、礦山冶金、環保、造紙、化工等行業。


    電(dian)(dian)(dian)(dian)動(dong)(dong)蝶(die)閥(fa)依據(ju)構(gou)造可分為電(dian)(dian)(dian)(dian)動(dong)(dong)中線密(mi)封(feng)蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)雙(shuang)偏心蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)三偏心蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)襯(chen)膠蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)襯(chen)氟蝶(die)閥(fa)等,依據(ju)功用(yong)又可分為電(dian)(dian)(dian)(dian)動(dong)(dong)軟密(mi)封(feng)蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)金屬密(mi)封(feng)蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)通風(feng)蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)真(zhen)空蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)伸縮蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)衛生級蝶(die)閥(fa)等,依據(ju)銜接方(fang)式分為電(dian)(dian)(dian)(dian)動(dong)(dong)對(dui)夾蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)法蘭(lan)蝶(die)閥(fa)、電(dian)(dian)(dian)(dian)動(dong)(dong)焊接蝶(die)閥(fa)等等。


    在選(xuan)(xuan)型時,依據介質溫度(du)的(de)不同,在常溫時,能夠選(xuan)(xuan)擇(ze)(ze)電(dian)動軟密(mi)封(feng)蝶閥,在溫度(du)較(jiao)高時(高于150度(du)),則必(bi)需選(xuan)(xuan)擇(ze)(ze)電(dian)動金屬密(mi)封(feng)蝶閥。中線密(mi)封(feng)蝶閥適用于開關兩位控制(zhi)的(de)場(chang)所,而三偏心(xin)蝶閥,則因(yin)具有近似等百(bai)分比(bi)的(de)流(liu)量特性,比(bi)擬適用于需求連(lian)續調理的(de)工況。


    而關于腐蝕性的(de)介(jie)質,能(neng)夠運(yun)用(yong)(yong)電(dian)(dian)動襯(chen)氟或(huo)者電(dian)(dian)動襯(chen)膠蝶(die)閥(fa)(fa)(fa)(fa)。在需(xu)求抽真空的(de)場所,還有電(dian)(dian)動真空蝶(die)閥(fa)(fa)(fa)(fa)能(neng)夠選(xuan)用(yong)(yong)。在大口徑的(de)通風管道或(huo)者煙氣管道上,電(dian)(dian)動通風蝶(die)閥(fa)(fa)(fa)(fa)、電(dian)(dian)動煙氣蝶(die)閥(fa)(fa)(fa)(fa)就比擬適用(yong)(yong)了。隨著加工工藝的(de)不時(shi)改良,和(he)資料學的(de)進(jin)步,電(dian)(dian)動蝶(die)閥(fa)(fa)(fa)(fa)在現代工業中運(yun)用(yong)(yong)的(de)范圍將會愈加普(pu)遍。
