style="font-size:16px;">蝶閥適用于口徑較大（如DN﹥600mm）及結(jié)構(gòu)長度要求短，以及需要進(jìn)行流量調(diào)節(jié)及啟閉要求快速的場合，涇川蝶閥市場報(bào)價(jià)，一般用于溫度≤80℃、壓力≤、油品和壓縮空氣等介質(zhì)；由于蝶閥相對于閘閥、球閥壓力損失比較大，故蝶閥適用于壓力損失要求不嚴(yán)的管路系統(tǒng)中。蝶閥的優(yōu)點(diǎn)1、啟閉方便迅速、省力、流體阻力小，涇川蝶閥市場報(bào)價(jià)，可以經(jīng)常操作。2、結(jié)構(gòu)簡單，涇川蝶閥市場報(bào)價(jià)，外形尺寸小，結(jié)構(gòu)長度短，體積小，重量輕，適用于大口徑的閥門。3、可以運(yùn)送泥漿，在管道口積存液體**少。4、低壓下，可以實(shí)現(xiàn)良好的密封。5、調(diào)節(jié)性能好。6、全開時(shí)閥座通道有效流通面積較大，流體阻力較小。7、啟閉力矩較小，由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用基本相等，而產(chǎn)生轉(zhuǎn)矩的方向相反，因而啟閉較省力。8、密封面材料一般采用橡膠、塑料、故低壓密封性能好。</span>

style="font-size:16px;">在管道上主要起切斷和節(jié)流作用。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。蝶板由閥桿帶動(dòng)，若轉(zhuǎn)過90°，便能完成一次啟閉。改變蝶板的偏轉(zhuǎn)角度，即可控制介質(zhì)的流量。性能特點(diǎn)：優(yōu)勢：1、啟閉方便迅速、省力、流體阻力小，可以經(jīng)常操作。2、結(jié)構(gòu)簡單，外形尺寸小，結(jié)構(gòu)長度短，體積小，重量輕，適用于大口徑的閥門。3、相比其他種類同口徑閥門，造價(jià)低。4、低壓下，可以實(shí)現(xiàn)良好的密封。5、調(diào)節(jié)性能好。6、全開時(shí)閥座通道有效流通面積較大，流體阻力較小。7、啟閉力矩較小，由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用基本相等，而產(chǎn)生轉(zhuǎn)矩的方向相反，因而啟閉較省力。8、密封面材料一般采用橡膠、塑料、故低壓密封性能好。9、安裝方便。10、操作靈活省力，可選擇手動(dòng)、電動(dòng)、氣動(dòng)、液壓方式。劣勢：1、由于蝶閥的結(jié)構(gòu)和密封材料的限制，使用壓力和工作溫度范圍小。2、由于受閥門結(jié)構(gòu)的限制，密封性能相對于球閥較差，故用于密封要求不是很高的地方。</span>

style="font-size:16px;">選用蝶閥應(yīng)遵循的原則：⑴與閘閥、截止閥、球閥、旋塞閥等相比，蝶閥的結(jié)構(gòu)尺寸小，重量**輕，價(jià)格便宜，故對于大尺寸管道，用蝶閥代替其他切斷閥對降低裝置建設(shè)成本是非常有利的;⑵與閘閥、截止閥、球閥、旋塞閥等相比，其密封可靠性**差，故不宜用于高溫(如200℃及以上)、高壓(如Class600及以上)的介質(zhì)工況，但個(gè)別工廠的特殊設(shè)計(jì)例外;⑶對于軟密封蝶閥，雖然價(jià)格會(huì)更便宜，但受溫度和壓力的限制，高溫高壓時(shí)不能使用;⑷蝶閥無密閉閥腔，適宜用于低溫介質(zhì)工況或可能發(fā)生氣化的介質(zhì)工況;⑸不能用于有通球要求的管路切斷;⑹可以做襯里;⑺適宜用于壓力脈動(dòng)介質(zhì)工況和可能產(chǎn)生汽蝕的介質(zhì)工況;適宜用于高壓氧氣工況;適宜用于可能產(chǎn)生沖刷或沖刷腐蝕的介質(zhì)工況;⑻相對于閘閥、球閥來說，由于蝶閥的壓</span><span style="font-size:16px;">力</span><span style="font-size:16px;">損失比較大，故不適用于對壓力損失要求嚴(yán)格的管路系統(tǒng)中。</span> </p><p> <span style="font-size:16px;">由于蝶閥閥板的運(yùn)動(dòng)帶有擦拭性，故大多數(shù)蝶閥可用于帶懸浮固體顆粒的介質(zhì)，依據(jù)密封件的強(qiáng)度也可用于粉狀和顆粒狀介質(zhì)。蝶閥是用圓盤式啟閉件往復(fù)回轉(zhuǎn)90度左右來開啟、關(guān)閉和調(diào)節(jié)流體通道的一種閥門。蝶閥不僅結(jié)構(gòu)簡單、體積小、重量輕、材料耗用省，安裝尺寸小，而且驅(qū)動(dòng)力矩小，操作簡便、迅速，并且還可同時(shí)具有良好的流量凋節(jié)功能和關(guān)閉密封特性，是近十幾年來發(fā)展**快的閥門品種之一。特別是在美、日、德、法、意等工業(yè)發(fā)達(dá)國家，蝶閥的使用非常***．其使用的品種和數(shù)量仍在繼續(xù)擴(kuò)大，并向高溫、高壓、大口徑、高密封性、長壽命、優(yōu)良的調(diào)節(jié)特性以及一閥多功能方向發(fā)展，其可靠性及其他性能指標(biāo)均達(dá)較高水平，并已部分取代截止閥、閘閥和球閥。隨著蝶閥技術(shù)的進(jìn)步。在可以預(yù)見的短時(shí)間內(nèi)，</span><span
