style="text-indent:25px">蝶閥的構(gòu)造類型很多，以往常見的有薄膜式、內(nèi)彈簧活塞式等。蝶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)。近年來又出現(xiàn)一些新型蝶閥，如定比式蝶閥。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。這種蝶閥工作平穩(wěn)無振動；閥體內(nèi)無彈簧，通風(fēng)蝶閥采購，故無彈簧銹蝕、金屬疲勞失效之慮；密封性能良好不滲漏，通風(fēng)蝶閥采購，因而既減動壓（水流動時(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。蝶閥通常有DN50～DN100等多種規(guī)格，通風(fēng)蝶閥采購，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％。蝶閥啟閉件是一個(gè)圓盤形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。通風(fēng)蝶閥采購</p><div
