力士樂疊加式液控單向閥的構(gòu)造類型很多，以往常見的有薄膜式、內(nèi)彈簧活塞式等。減壓閥的基本作用原理是靠閥內(nèi)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(cè)的進出口水壓差自動調(diào)節(jié)。近年來又出現(xiàn)些新型減壓閥，如定比式減壓閥，其構(gòu)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(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無振動；閥體內(nèi)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(guī)格，閥前、后的工作壓力分別為＜1MPa和0．1～0．5MPa，調(diào)壓范圍誤差為±5％～10％。 應(yīng)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(tǒng)流量分布合理、改善了系統(tǒng)布局與工況，因此總體上講仍是節(jié)能的。
