style="font-size:16px;">蝶閥是指啟閉件(蝶板)由閥桿帶動(dòng)，并繞閥桿的軸線作旋轉(zhuǎn)運(yùn)動(dòng)的閥門。蝶閥的特點(diǎn)是體積小，質(zhì)量輕、結(jié)構(gòu)簡(jiǎn)單，啟閉迅速、密封和調(diào)節(jié)性能良好，且可實(shí)現(xiàn)分級(jí)流量控制、流阻和操作力矩較小、由于蝶板的運(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介質(zhì)。蝶閥的種類很多，根據(jù)其結(jié)構(gòu)特點(diǎn)和用途，一般可分為兩大類：密封型蝶閥和非密封蝶閥。密封型蝶閥在關(guān)閉時(shí)能夠完全保證密封，在管路中可以作為切斷用;非密封型蝶閥在關(guān)閉時(shí)不能保證完全密封，只能在管道中做調(diào)節(jié)用或在密封要求不嚴(yán)的管道中使用。蝶閥和通道的連接方式有：對(duì)夾式、雙法蘭式、和單法蘭式。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，白銀區(qū)蝶閥價(jià)格，重量**輕，價(jià)格便宜，白銀區(qū)蝶閥價(jià)格，白銀區(qū)蝶閥價(jià)格，故對(duì)于大尺寸管道。</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(jiǎn)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(jiǎn)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(guó)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(zhǎng)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 style="font-size:16px;">特</span><span style="font-size:16px;">別是在大中型口徑、中低壓力的使用領(lǐng)域，蝶閥將會(huì)成為主導(dǎo)的閥門形式。</span> 金川區(qū)蝶閥費(fèi)用蝶閥適用于流量調(diào)節(jié)。</p><div style="width:100%;text-align:

style="font-size:16px;">閘閥近年來，國(guó)內(nèi)不少閥門制造廠家，研制、仿制軟密封閘閥，這種閘閥比傳統(tǒng)的楔式或平行雙閘板式閘閥有如下特點(diǎn)：軟密封閘閥的閥體、閥蓋采用精密鑄造法鑄造，一次成型，基本不機(jī)械加工，不使用密封銅環(huán)，節(jié)約有色金屬。軟密封閘閥底部無凹坑，不積存渣物，閘閥啟閉的故障率低。軟密封襯膠閥板尺寸統(tǒng)一，互換性強(qiáng)。因此軟密封閘閥將是供水行業(yè)樂意采用的一種形式。目前國(guó)內(nèi)制造的軟密封閘閥口徑達(dá)1500mm，但多數(shù)廠家制造的口徑在80-300mm間，國(guó)內(nèi)制造工藝上尚有諸多問題。軟密封閘閥的關(guān)鍵部件是襯膠閥板，而襯膠閥板的技術(shù)要求較高，國(guó)外也不是所有廠家都能達(dá)到的，往往是從質(zhì)量可靠的廠方購(gòu)進(jìn)組裝。國(guó)內(nèi)軟密封閘閥的銅螺母塊是嵌掛在襯膠閥板上方的，類似閘閥的結(jié)構(gòu)，由于螺母塊的活動(dòng)摩擦容易使閥板的襯膠剝離。國(guó)外某公司的軟密封閘閥，銅螺母塊是鑲嵌在襯膠閘板內(nèi)，形成整體，克服了上述缺點(diǎn)，但閥蓋與閥體組合的同心度要求較高。</span> </p><p> <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。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>
