style="font-size:16px;">焊接式蝶閥是一種非密閉型蝶閥，適用于建材、冶金、礦山、電力等生產(chǎn)過(guò)程種介質(zhì)溫度≤300℃公稱(chēng)壓力為，用以連通、啟閉或調(diào)節(jié)介質(zhì)量。蝶閥按結(jié)構(gòu)形式可分為偏置板式、垂直板式、斜板式和杠桿式。按密封形式可分為軟密封型和硬密封型兩種。軟密封型一般采用橡膠環(huán)密封，硬密封型通常采用金屬環(huán)密封。按連接型式可分為法蘭連接和對(duì)夾式連接；按傳動(dòng)方式可分為手動(dòng)、齒輪傳動(dòng)、氣動(dòng)、液動(dòng)和電動(dòng)幾種。工業(yè)**蝶閥的特點(diǎn)能耐高溫，適用壓力范圍也較高，閥門(mén)公稱(chēng)通徑大，閥體采用碳鋼制造，閥板的密封圈采用金屬環(huán)代替橡膠環(huán)。大型高溫蝶閥采</span><span style="font-size:16px;">用鋼板焊接制造，主要用于高溫介質(zhì)的煙風(fēng)道和煤氣管道。蝶閥具有結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕、材料耗用省，安裝尺寸小，開(kāi)關(guān)迅速、90°往復(fù)回轉(zhuǎn)，驅(qū)動(dòng)力矩小等特點(diǎn)，用于截?cái)?、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(guān)閉密封性能。</span> </p><p> <span style="font-size:16px;"></span><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(pán)形的蝶板，在閥體內(nèi)繞其自身的軸線(xiàn)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(guò)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(shì)：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(jiǎn)單，外形尺寸小，結(jié)構(gòu)長(zhǎng)度短，體積小，重量輕，適用于大口徑的閥門(mén)。3、相比其他種類(lèi)同口徑閥門(mén)，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(kāi)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(shì)：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(mén)結(jié)構(gòu)的限制，密封性能相對(duì)于球閥較差，故用于密封要求不是很高的地方。</span> 閥門(mén)的密封性能是指閥門(mén)各密封部位阻止介質(zhì)泄漏的能力。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="沙坡頭區(qū)蝶閥生產(chǎn)廠(chǎng)家,蝶閥"
