SMC氣缸型號 日本SMC smc* SMC中國 SMC減壓閥 SMCAR50K-N06-Z
減壓閥的種類很多,，常見的有：先導(dǎo)活塞式減壓閥、薄膜式減壓閥,、波紋管式減壓閥,、比例式減壓閥、自力式減壓閥,、直接作用活塞式減壓閥,、背壓調(diào)節(jié)閥等等。它們分別適用于不同的工作介質(zhì),。 不同的形式有不同的具體工作原理,。
減壓閥是一種自動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,，以保證給水系統(tǒng)中各用水點獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費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(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；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%,。 JB/T2203－1999《減壓閥結(jié)構(gòu)長度》為主的通用類,。目前國內(nèi)大多數(shù)減壓閥生產(chǎn)廠家均按本標(biāo)準(zhǔn)設(shè)計生產(chǎn)，但本標(biāo)準(zhǔn)也不盡*,，規(guī)格不全,。氣體減壓閥zui大公稱通徑為DN500，水用減壓閥zui大公稱通徑DN1000,。根據(jù)廠家所生產(chǎn)的減壓閥規(guī)格及掌握的資料來看,，各廠家連接尺寸也不盡統(tǒng)一，如 DN500氣體減壓閥,，建議通用機(jī)械研究所對JB/T2203－1999《減壓閥結(jié)構(gòu)長度》進(jìn)行修訂,。建議設(shè)計院及用戶按標(biāo)準(zhǔn)選用，減壓閥生產(chǎn)廠家按標(biāo)準(zhǔn)設(shè)計制造,。
