電動(dong)三(san)通(tong)(tong)(tong)球閥(fa)(fa)(fa)是(shi)由角行(xing)(xing)程 電動(dong)執行(xing)(xing)器 及三(san)通(tong)(tong)(tong)球閥(fa)(fa)(fa)組成，是(shi)一(yi)種旋轉類切(qie)斷、 調節閥(fa)(fa)(fa) 門，具(ju)有(you)關閉嚴密(mi)，結構(gou)緊湊，重量輕，維修(xiu)方(fang)便等優點。電動(dong)三(san)通(tong)(tong)(tong)球閥(fa)(fa)(fa)以220V單(dan)(dan)相(xiang)(xiang)(xiang)交流(liu)電為動(dong)力源，接受控(kong)(kong)制(zhi)系(xi)統(tong)的(de)(de)開關信(xin)號，通(tong)(tong)(tong)過單(dan)(dan)相(xiang)(xiang)(xiang)電源切(qie)換(huan)(huan)驅(qu)動(dong)可(ke)(ke)逆(ni)單(dan)(dan)相(xiang)(xiang)(xiang)齒(chi)輪減速機，使球閥(fa)(fa)(fa)按規定要求對管路進(jin)行(xing)(xing)切(qie)換(huan)(huan)。兩閥(fa)(fa)(fa)座(zuo)密(mi)封(feng)電動(dong)三(san)通(tong)(tong)(tong)球閥(fa)(fa)(fa)具(ju)有(you)結構(gou)緊湊、外型(xing)美(mei)觀(guan)、密(mi)封(feng)性能(neng)好，它能(neng)實現對管道(dao)中(zhong)介質流(liu)向(xiang)的(de)(de)切(qie)換(huan)(huan)，也(ye)(ye)(ye)能(neng)使相(xiang)(xiang)(xiang)互(hu)垂直的(de)(de)兩個(ge)通(tong)(tong)(tong)道(dao)連(lian)(lian)通(tong)(tong)(tong)或(huo)關閉。四(si)閥(fa)(fa)(fa)座(zuo)密(mi)封(feng)電動(dong)三(san)通(tong)(tong)(tong)球閥(fa)(fa)(fa)具(ju)有(you)造型(xing)美(mei)觀(guan)、結構(gou)緊湊合理。它不(bu)僅可(ke)(ke)實現介質流(liu)向(xiang)的(de)(de)切(qie)換(huan)(huan)，也(ye)(ye)(ye)可(ke)(ke)使三(san)個(ge)通(tong)(tong)(tong)道(dao)相(xiang)(xiang)(xiang)互(hu)連(lian)(lian)通(tong)(tong)(tong)，現時也(ye)(ye)(ye)可(ke)(ke)關閉任一(yi)通(tong)(tong)(tong)道(dao)，使另外兩個(ge)通(tong)(tong)(tong)道(dao)連(lian)(lian)通(tong)(tong)(tong)，靈活(huo)控(kong)(kong)制(zhi)管路中(zhong)介質的(de)(de)合流(liu)或(huo)分(fen)流(liu)。電動(dong)三(san)通(tong)(tong)(tong)球閥(fa)(fa)(fa)適用于供水、石化、冶金(jin)、礦山、輕紡、能(neng)源、造紙、食(shi)品、鋼鐵等管路系(xi)統(tong)中(zhong)對介質流(liu)向(xiang)進(jin)行(xing)(xing)切(qie)換(huan)(huan)以及對介質的(de)(de)分(fen)流(liu)或(huo)混合流(liu)體。

電動三(san)(san)(san)通(tong)(tong)球閥(fa)可分(fen)為(wei)L形(xing)和T形(xing)，L形(xing)（Q944F）三(san)(san)(san)通(tong)(tong)球閥(fa)用(yong)于(yu)(yu)介質(zhi)流向(xiang)的切換(huan)，能使(shi)相互(hu)垂直的兩(liang)(liang)個(ge)通(tong)(tong)道(dao)連接；T形(xing)（Q945F）三(san)(san)(san)通(tong)(tong)球閥(fa)用(yong)于(yu)(yu)介質(zhi)分(fen)流、合(he)流及流向(xiang)切換(huan)。T形(xing)三(san)(san)(san)通(tong)(tong)球閥(fa)可以使(shi)三(san)(san)(san)個(ge)通(tong)(tong)道(dao)相互(hu)連通(tong)(tong)或使(shi)其(qi)中的兩(liang)(liang)個(ge)通(tong)(tong)道(dao)連通(tong)(tong)。三(san)(san)(san)通(tong)(tong)球閥(fa)一般(ban)采(cai)用(yong)兩(liang)(liang)閥(fa)座結構，亦可根據用(yong)戶要求采(cai)用(yong)四閥(fa)座結構。
