動態(tài)流量平衡閥跟據(jù)系統(tǒng)工況變動而自動變化阻力系數(shù)，在一定的壓差范圍內(nèi)，可以較有效地控制通過的流量保持一個常值。動態(tài)流量平衡閥使閥膽能根據(jù)水系統(tǒng)不時的壓差變化而變化，保證不會超過原先設定的水流量并吸收過量的壓差，從而實現(xiàn)整個水系同壓力和流量的自動平衡。動態(tài)流量平衡閥可稱為固定式動態(tài)流量平衡閥有法蘭和對夾的兩種，閥體內(nèi)安裝多個閥芯，其閥芯決定流量，因此出廠前通常就把流量設定好，即可使系統(tǒng)流量自動恒定在要求的設定值；選用動態(tài)流量平衡閥時，應首先進行水力計算，確定流量、壓差范圍。

style="text-indent:25px">多功能止回閥是指依靠介質(zhì)本身流動而自動開、閉閥瓣，用來防止介質(zhì)倒流的閥門，又稱逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動閥門，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動電動機反轉(zhuǎn)，以及容器介質(zhì)的泄放。止回閥還可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)提供補給的管路上。止回閥主要可分為旋啟式止回閥（依重心旋轉(zhuǎn)）與升降式止回閥（沿軸線移動）。這種類型的閥門的作用是只允許介質(zhì)向一個方向流動，而且阻止方向流動。廣東多功能止回閥的</p><p
