容積式換熱器利用增壓泵出口處止回閥和電磁閥前閥，當用戶系統運行時，即用戶增壓泵啟動時，電磁閥前閥通電，板式熱交換器當用戶系統內壓力超過定壓壓力(確保用戶系統不倒空)后，電磁閥前閥自動開啟，用戶回水經閥前閥定壓為用戶系統的定壓壓力，并容積式換熱器減壓至和熱網回水管壓力相同；當用戶容積式換熱器增壓泵停止運行時，電磁閥前閥斷電自動關閉，這樣用戶系統內的水就被密閉起來，如果不漏水，可保證用容積式換熱器戶系統內壓力在較長時間維持在定壓壓力左右。也就是說，板式熱交換器價格不(bu)論(lun)增壓(ya)(ya)冪運行還(huan)是不(bu)運行，用戶(hu)系(xi)締內(nei)的壓(ya)(ya)力都町堆持在倧壓(ya)(ya)壓(ya)(ya)力范(fan)圍(wei)內(nei)。
