style="text-indent:25px">閥座的構(gòu)造類型很多，以往常見的有薄膜式、內(nèi)彈簧活塞式等。閥座的基本作用原理是靠閥座內(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座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)。近年來(lái)又出現(xiàn)一些新型閥座，如定比式閥座。定比減壓原理是利用閥座體中浮動(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。這種閥座工作平穩(wěn)無(wú)振動(dòng)；閥座體內(nèi)無(wú)彈簧，故無(wú)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)壓又減靜壓；特別是在減壓的同時(shí)不影響水流量。閥座通常有DN50～DN100等多種規(guī)格，閥座前、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％。湖北球閥閥座磨損修復(fù)各類橡膠,塑料，金屬材料均可作為閥座材質(zhì)。</p><div
