日本DAIKIN疊加型減壓閥#DAIKIN天津總現(xiàn)貨
減壓閥的構(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)。2007年以來又出現(xiàn)一些新型減壓閥,，如定比式減壓閥,。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,；密封性能良好不滲漏,，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DN15～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%,。 RP15C12H-15-30、RP15C13H-15-30,、RP15C22H-15-30,、RP15C23H-15-30、RP15C11H-22-30,、RP15C12H-22-30,、RP15C13H-22-30、RP15C22H-22-30,、RP15C23H-22-30,、RP15C11JA-15-30、RP15C12JA-15-30,、RP15C13JA-15-30,、RP15C22JA-15-30、RP15C23JA-15-30,、RP15C11JB-15-30,、RP15C12JB-15-30、RP15C13JB-15-30,、RP15C22JB-15-30,、RP15C23JB-15-30、RP15C11JP-15-30,、RP15C12JP-15-30,、RP15C13JP-15-30、RP15C22JP-15-30,、RP15C23JP-15-30,、RP23A1-22-30、RP23A2-22-30,、RP23A3-22-30,、RP23A1-37-30,、RP23A2-37-30、RP23A3-37-30,、RP23A2-22-30RC,、RP23A3-37-30RC、RP23C11H-22-30,、RP23C12H-22-30,、RP23C13H-22-30,、RP23C22H-22-30,、RP23C23H-22-30、RP23C11H-37-30,、RP23C12H-37-30,、RP23C13H-37-30、RP23C22H-37-30,、RP23C23H-37-30,、RP23C11JA-37-30、RP23C12JA-37-30,、RP23C13JA-37-30,、RP23C22JA-37-30、RP23C23JA-37-30,、RP23C11JB-37-30,、RP23C12JB-37-30、
