style="text-indent:25px">蝶閥處于徹底開啟方位時，蝶板厚度是介質(zhì)流經(jīng)閥體時的阻力，因而通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。采用金屬密封的閥門一般比彈性密封的閥門壽命長，但很難做到徹底密封。金屬密封能習慣較高的工作溫度，彈性密封則具有受溫度限制的缺點。如果要求蝶閥作為流量控制運用，主要的是正確選擇閥門的尺度和類型。蝶閥的結構原理特別適合制作大口徑閥門。蝶閥不僅在石油、煤氣、化工、水處理等一般工業(yè)上得到普遍應用，并且還應用于熱電站的冷卻水系統(tǒng)。</p><p style="text-indent:25px">蝶閥特點：蝶閥具有結構簡單、體積小、重量輕、材料耗用省，安裝尺寸小，開關迅速、90°往復回轉(zhuǎn)，驅(qū)動力矩小等特點，用于截斷、接通、調(diào)節(jié)管路中的介質(zhì)，具有良好的流體控制特性和關閉密封性能。蝶閥可以運送泥漿，在管道口積存液體少。低壓下，可以實現(xiàn)良好的密封。調(diào)節(jié)性能好。蝶板的流線型設計，使流體阻力損失小，可謂是一種節(jié)能型產(chǎn)品。閥桿為通桿結構，經(jīng)過調(diào)質(zhì)處理，有良好的綜合力學性能和抗腐蝕性，抗擦傷性。蝶閥啟閉時閥桿只作旋轉(zhuǎn)運動而不作升降運行，閥桿的填料不易破壞，密封可靠。與蝶板錐銷固定，外伸端為防沖出型設計，以免在閥桿與蝶板連接處意外斷裂時閥桿崩出。蝶閥操作靈活省力，可選擇手動、電動、氣動、液壓方式。</p><div

style="text-indent:25px">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。減壓閥普遍用于高層建筑、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?shù)姆账畨汉土髁?。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)。蝶閥蝶板的運動帶有擦拭性，故大多數(shù)的蝶閥可用于帶懸浮固體顆粒的介質(zhì)。鋁合金手動蝶閥廠商哪家好</p><p

style="text-indent:25px">減壓閥的構造類型很多，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)。近年來又出現(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DN50～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％。對夾式自動蝶閥哪家專業(yè)</p><p
