動態電動平衡閥是區別于傳統的電動調節閥的新一代產品,是動態平衡與電動調節一體化的產品。動態平衡電動調節閥是以利用介質自身的壓力變化控制,是電動比例積分控制的一種雙閥芯的多功能閥門,廣泛用于供熱及制冷空調等非腐蝕性介質的流量控制閥門,也可以做電關閉閥用。運行前一次性調節,既可以使系統流量翕動恒定在要求的設定值。
動態電動平衡閥工作原理
  如下圖所示,在系統負荷波動較大的變流量系統中,當系統壓力變化時,動態平衡電動調節閥二端的壓差(P1-P3)也隨之變化: 
  ⑴、當進口壓力P1升高時,(P1-P2)增大,這時電動閥閥芯向上運動,使P1、P2間開度減少,閥芯壓力P2降低;當進口壓力P1降低時,(P1-P2)減小,這時電動閥閥芯向下運動,使P1、P2間開度增大,閥芯壓力P2升高。因此,無論系統的壓力怎樣變化,通過電動閥閥芯的調節作用,P2、P3間的壓差始終保持不變。因此這種動閥的抗干擾能力強,具有動態平衡的功能;
  ⑵、當直行程電動執行器接受控制信號使閥軸延A—B向上下運動(或角行程電動執行器接受控制信號使閥軸延R向旋轉)時,P2、P3間的開度也隨之變化。由于不管系統壓差(P1-P3)如何變化,P2、P3間的壓差(P2-P3)始終不變,因此對應于任一開度位置,其輸送的水流量都是一定的,并且電動調節閥實際的流量特性曲線與其理想的流量特性曲線是一致的,沒有偏離。因此這種電動調節閥較傳統的電動調節閥具有更好的調節特性。
