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>

style="font-size:16px;">蝶閥的選用原則1、由于蝶閥相對(duì)于閘閥，球閥壓力損失比較大，故適應(yīng)于壓力損失要求不嚴(yán)的管路系統(tǒng)中2、由于蝶閥可以用流量調(diào)節(jié)，故在需要進(jìn)行流量調(diào)節(jié)的管路中宜于選用3、由于蝶閥的結(jié)構(gòu)和密封材料的限制，不宜用于高溫，高壓的管路系統(tǒng)。一般工作溫度在300℃以下，公稱壓力在PN40以下。4、由于蝶閥結(jié)構(gòu)長(zhǎng)度比較短，且又可以做成大口徑，故在結(jié)構(gòu)長(zhǎng)度要求短的場(chǎng)合或是大口徑閥門(mén)（如DN1000以上），宜選用蝶閥。5、由于蝶閥*旋轉(zhuǎn)90°就能開(kāi)啟或關(guān)閉，因此在啟閉要求快的場(chǎng)合宜選用蝶閥蝶閥***用于℃的各種介質(zhì)。閥桿只做旋轉(zhuǎn)運(yùn)動(dòng)，蝶板和</span><span

style="font-size:16px;">蝶閥適用于流量調(diào)節(jié)。由于蝶閥在管路中的壓力損失比較**約是閘閥的三倍，因此在選擇蝶閥時(shí)，應(yīng)充分考慮管路系統(tǒng)受壓力損失的影響，還應(yīng)考慮關(guān)閉時(shí)蝶板承受管道介質(zhì)壓力的堅(jiān)固性。此外，還必須考慮在高溫下彈性閥座材料所承受工作溫度的限制。蝶閥的結(jié)構(gòu)長(zhǎng)度和總體高度較小，開(kāi)啟和關(guān)閉速度快，且具有良好的流體控制特性，蝶閥的結(jié)構(gòu)原理適合制作大口徑閥門(mén)。當(dāng)要求蝶閥作控制流量使用時(shí)，重要的是正確選擇蝶閥的尺寸和類(lèi)型，使之能恰當(dāng)?shù)?、有效地工作。通常，在?jié)流、調(diào)節(jié)控制與泥漿介質(zhì)中，要求結(jié)構(gòu)長(zhǎng)度短，啟閉速度快(1/4轉(zhuǎn))。低壓截止(壓差小)，推薦選用蝶閥。在雙位調(diào)節(jié)、縮口地通道、低噪聲、有氣穴和氣化現(xiàn)象，向大氣少量滲漏，具有磨蝕性介質(zhì)時(shí)，可以選用蝶閥。</span>
