減壓閥簡介及主要*牌
減壓閥是一種自動(dòng)降低管路工作壓力的專門裝置,它可將閥前管路較高的液體壓力減少至閥后管路所需的水平。這里的傳輸介質(zhì)主要是水。減壓閥廣泛用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場合,以*保*給水系統(tǒng)中各用水點(diǎn)獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費(fèi)程度幾乎同給水系統(tǒng)的水壓大小成正比,因此減壓閥具有改善系統(tǒng)運(yùn)行工況和潛在節(jié)水作用,據(jù)統(tǒng)計(jì)其節(jié)水效果約為30%。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(duì)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(jìn)出口水壓差自動(dòng)調(diào)節(jié)。2007年上海閔高閥門有限公司引進(jìn)國外技術(shù),生產(chǎn)出一些新型減壓閥,如定比式減壓閥。定比減壓原理是利用閥體中浮動(dòng)活塞的水壓比控制,進(jìn)出口端減壓比與進(jìn)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(dòng),使得國內(nèi)減壓閥生產(chǎn)技術(shù)進(jìn)一步提高;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(dòng)壓(水流動(dòng)時(shí))又減靜壓(流量為0時(shí));特別是在減壓的同時(shí)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%。
