力士樂疊加式液控單向閥的構造類型很多，以往常見的有薄膜式、內彈簧活塞式等。減壓閥的基本作用原理是靠閥內流道對水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側的進出口水壓差自動調節。近年來又出現些新型減壓閥，如定比式減壓閥，其構造原理如圖14．2－2所示。定比減壓原理是利用閥體中浮動活塞的水壓比控制，進出口端減壓比與進出口側活塞面積比成反比。這種減壓閥工作平穩無振動；閥體內無彈簧，故無彈簧銹蝕、金屬疲勞失效之慮；密封良好不滲漏，因而既減動壓（水流動時）又減靜壓（流量為0時）；特別是在減壓的同時不影響水流量。 減壓閥通常有DN50～DN100等多種規格，閥前、后的工作壓力分別為＜1MPa和0．1～0．5MPa，調壓范圍誤差為±5％～10％。 應該看到，水流通過減壓閥雖有很大的水頭損失，但由于減少了水的浪費并使系統流量分布合理、改善了系統布局與工況，因此總體上講仍是節能的。
