style="font-size:16px;">在項目上是用對夾，還是支耳，還是法蘭。這個問題可以簡化為是用對夾還是法蘭。法蘭比對夾的一個重要的優(yōu)勢就是可以單夾在一側(cè)管道上，可以做盲板使用，中衛(wèi)蝶閥聯(lián)系電話，也可以在另一側(cè)需要維修，更換時，只需要關(guān)閉閥板，卸掉需施工側(cè)的管道即可。對夾蝶閥就做不到這個功能。螺紋孔的支耳和法蘭蝶閥的選擇。提到這個討論，主要是現(xiàn)在一個特殊的垂直行業(yè)，數(shù)據(jù)中心行業(yè)。因為這個行業(yè)的環(huán)形管網(wǎng)有大量的蝶閥的設(shè)計，并且有這較高的安全要求，每一段都能快速關(guān)斷并在不影響系統(tǒng)的情況下進(jìn)行維修。因此有大量的支耳和法蘭蝶閥應(yīng)用在這個市場。支耳能得以應(yīng)用是有兩個原因，首先是它能起到單夾在一側(cè)管道上的功能，二是價格便宜，中衛(wèi)蝶閥聯(lián)系電話。所以很迎合市場的需求。我們以常見的DN400口徑為例，支耳的厚度在102mm，因此單側(cè)的受力是實際上是靠不到5公分的螺栓來支撐，對螺栓的疲勞強度影響較大，中衛(wèi)蝶閥聯(lián)系電話，使用可靠性要遠(yuǎn)遠(yuǎn)低于法蘭連接形式。所以不建議在項目上大量使用支耳蝶閥。</span>

style="font-size:16px;">閘閥近年來，國內(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：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。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)量可靠的廠方購進(jìn)組裝。國內(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)，由于螺母塊的活動摩擦容易使閥板的襯膠剝離。國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，但閥蓋與閥體組合的同心度要求較高。</span>

style="font-size:16px;">品</span><span style="font-size:16px;">，它的特點是做節(jié)流用時非常簡便，同時擁有良好的耐久性和安全可靠性，根據(jù)自己的工況需要選擇符合的閥門型號。</span> </p><p> <span style="font-size:16px;">蝶閥又叫翻板閥，是一種結(jié)構(gòu)簡單的調(diào)節(jié)閥，同時也可用于低壓管道介質(zhì)的開關(guān)控制。蝶閥是指關(guān)閉件（閥瓣或蝶板）為圓盤，圍繞閥軸旋轉(zhuǎn)來達(dá)到開啟與關(guān)閉的一種閥，在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個圓盤形的蝶板，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。蝶閥適用于發(fā)生爐、煤氣、天然氣、液化石油氣、城市煤氣、冷熱空氣、化工冶煉和發(fā)電環(huán)保等工程系統(tǒng)中輸送各種腐蝕性、非腐蝕性流體介質(zhì)的管道上，用于調(diào)節(jié)和截斷介質(zhì)的流動。蝶閥所適用的場合蝶閥適用于流量調(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，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)閉時蝶板承受管道介質(zhì)壓力的堅固性。此外，還必須考慮在高溫下彈</span><span

style="font-size:16px;">在啟閉軟密封閘閥時，千萬不應(yīng)關(guān)閉過死，只要達(dá)到止水效果即可，否則不易開啟或襯膠剝離。某閥門廠家，在閥門試壓檢驗時，使用扭力板手來控制關(guān)閉的程度，作為自來水公司的閥門操作人員也應(yīng)效仿此種啟閉方法。閘閥和蝶閥在管道使用中都是起開關(guān)，調(diào)節(jié)流量的作用。當(dāng)然在蝶閥和閘閥的選配過程中還是有方法的。在供水管網(wǎng)中為了降低管道覆土深度，一般口徑較大管道選配蝶閥，對覆土深度影響不大的，力求選配閘閥，但是同樣規(guī)格的閘閥價格又比蝶閥的價格高。至于口徑的分界線應(yīng)各地按具體情況考慮。從近十年使用情況而言，蝶閥出現(xiàn)的故障比閘閥高，因此在條件許可的情況下，擴(kuò)大閘閥的使用范圍是值得關(guān)注的。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。</span>

style="font-size:16px;">蝶閥是根據(jù)旋轉(zhuǎn)閥桿同時帶動蝶板轉(zhuǎn)動來做啟閉的一種閥門，在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，主要是旋轉(zhuǎn)蝶板90°來做流量控制，當(dāng)?shù)宓竭_(dá)90°時閥門處于全開狀態(tài)，同時可以改變蝶板的角度來調(diào)節(jié)介質(zhì)流量，一般安裝于管道的直徑方向。蝶閥與閥桿自身是沒有鎖定能力，為了有效的調(diào)節(jié)流量需裝蝸輪減速器，加裝蝸輪減速器的蝶閥不僅使蝶閥有自鎖能力，還能改變蝶閥的操作性能及更準(zhǔn)確的調(diào)節(jié)介質(zhì)流量。1、蝶閥在完全開啟時，具有較小的流阻。當(dāng)開啟在大約15°~70°之間時，又能進(jìn)行靈敏的流量控制，因而在大口徑的調(diào)節(jié)領(lǐng)域，蝶閥的應(yīng)用非常普遍。由于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)。依據(jù)密封件的強度，也可用于粉狀和顆粒狀介質(zhì)。</span>
