電動(dong)蝶(die)閥由壹體(ti)式(shi)電動(dong)執(zhi)行(xing)器(qi)和蝶(die)閥構(gou)成(cheng)。使(shi)用(yong)時(shi)，接(jie)入(ru)220VAC或(huo)者(zhe)380V電源(yuan)即(ji)可(ke)就地(di)控(kong)制或者(zhe)遠(yuan)程控(kong)制閥門啟閉(bi)，也可(ke)加(jia)入(ru)控(kong)制模塊,輸(shu)入(ru)控(kong)制信號(hao)（4-20mADC或(huo)1-5VDC）進(jin)行(xing)調(tiao)節控(kong)制。
電動(dong)執(zhi)行(xing)器(qi)由電機、減速器(qi)、力(li)矩控(kong)制器、行(xing)程(cheng)控(kong)制器、開(kai)度指(zhi)示(shi)器、手(shou)電切換(huan)機構(gou)等(deng)元器(qi)件(jian)構(gou)成(cheng) 電機：電機提供蝶(die)閥驅(qu)動(dong)力(li)矩 減速器(qi)：壹對正(zheng)齒(chi)輪和(he)蝸輪蝸(wo)桿(gan)組(zu)成(cheng)，電機力(li)矩經減速器(qi)傳遞(di)給(gei)輸(shu)出(chu)軸(zhou) 力(li)矩控(kong)制器：輸(shu)出(chu)軸(zhou)力(li)矩增大後，輸(shu)出(chu)力(li)矩開(kai)關工作(zuo)，達(da)到(dao)保(bao)護電動(dong)蝶(die)閥的目的(de) 行(xing)程(cheng)控(kong)制器：微動(dong)開(kai)關控(kong)制電機停轉(zhuan)，對閥門行(xing)程(cheng)進(jin)行(xing)精(jing)確控(kong)制 開(kai)度指(zhi)示(shi)器：指(zhi)示(shi)盤隨閥門的開(kai)閉過(guo)程同時(shi)轉(zhuan)動(dong)，以(yi)指(zhi)示(shi)閥門的開(kai)閉。
電動(dong)蝶(die)閥是(shi)電源(yuan)驅(qu)動(dong)的(de)自(zi)動(dong)閥門系(xi)統，也是(shi)工業自(zi)動(dong)化控(kong)制管路(lu)中(zhong)重要執(zhi)行(xing)單(dan)元。電動(dong)蝶(die)閥由壹體(ti)式(shi)電動(dong)執(zhi)行(xing)器(qi)和蝶(die)閥構(gou)成(cheng)。使(shi)用(yong)時(shi)，接(jie)入(ru)220VAC或(huo)者(zhe)380V電源(yuan)即(ji)可(ke)就地(di)控(kong)制或者(zhe)遠(yuan)程控(kong)制閥門啟閉(bi)，也可(ke)加(jia)入(ru)控(kong)制模塊,輸(shu)入(ru)控(kong)制信號(hao)（4-20mADC或(huo)1-5VDC）進(jin)行(xing)調(tiao)節控(kong)制。電動(dong)蝶(die)閥的電動(dong)執(zhi)行(xing)器(qi)輸(shu)出(chu)推(tui)力(li)大、較(jiao)氣(qi)動(dong)蝶(die)閥關閉速度(du)更快、運行(xing)更(geng)平(ping)穩(wen)，沖擊(ji)力(li)小
D973H由閥體(ti)、蝶(die)板(ban)、多(duo)層(ceng)次(ci)閥座、閥桿(gan)、傳動(dong)機構(gou)等(deng)主要部件(jian)組(zu)成(cheng)。因(yin)此(ci)被(bei)廣泛(fan)地應用到(dao)冶金(jin)、電力(li)、石(shi)油(you)、化工、空氣(qi)、煤(mei)氣(qi)、可(ke)燃氣體(ti)以(yi)及(ji)給(gei)排水(shui)等(deng)腐(fu)蝕性(xing)介(jie)質的管道(dao)上(shang)。D973H電動(dong)多(duo)層(ceng)次(ci)硬密封蝶(die)閥系(xi)列(lie)產(chan)品，系(xi)長(chang)壽(shou)命(ming)、節(jie)能型蝶(die)閥。其(qi)結構(gou)采(cai)用三維編(bian)心原(yuan)理(li)設(she)計，閥座采(cai)用硬軟(ruan)密封兼容的(de)多(duo)層(ceng)次(ci)結構(gou)，加(jia)工精工藝先(xian)進(jin)。
