良工三通保溫球閥概述：
BQ45F三(san)(san)通(tong)(tong)保(bao)溫(wen)(wen)球閥(fa)有兩閥(fa)座密封L型(xing)(xing)結(jie)(jie)構和四閥(fa)座密封T型(xing)(xing)結(jie)(jie)構兩種，用戶可根據(ju)工況實(shi)際情況選擇(ze)類型(xing)(xing)，該三(san)(san)通(tong)(tong)保(bao)溫(wen)(wen)球閥(fa)具有造型(xing)(xing)美觀，結(jie)(jie)構緊(jin)湊合理(li)，它不僅(jin)可實(shi)現介質流(liu)向的切換，也可使(shi)三(san)(san)個通(tong)(tong)道(dao)相互連通(tong)(tong)，同時也可關閉任一通(tong)(tong)道(dao)，使(shi)另外兩個通(tong)(tong)道(dao)連通(tong)(tong)，靈活控制管路(lu)中介質的合流(liu)與分流(liu)。
