style="text-indent:25px">液壓快速接頭在工業(yè)生產(chǎn)領(lǐng)域占有非常重要的地位。廣東常用液壓元件分類</p><p style="text-indent:25px">液壓快速接頭進出口不在同一水平線上，體型偏大、成本較高。第三代和第四代液壓快速接頭都是單調(diào)節(jié)式，不能滿足復(fù)雜工藝參數(shù)的使用要求。液壓快速接頭工作原理：1、減溫原理，減溫的基本原理是將減溫水直接噴入過熱蒸汽，經(jīng)噴嘴霧化的減溫水從蒸汽中吸收熱量、升溫、汽化與蒸汽混合，從而達到降低蒸汽溫度的作用。為了提高蒸汽品質(zhì)，一般減溫后的蒸汽溫度應(yīng)控制在高于飽和蒸汽溫度5℃以上。2、減壓原理，減壓的工作原理是蒸汽通過減溫減壓接頭（減壓接頭）或節(jié)流孔板（節(jié)流罩），流通面積減少，使蒸汽動能增加造成壓力損失，蒸汽的壓力能隨之減少而達到減壓的目的。廣東常用液壓元件分類</p></p><br
