style="font-size:16px;">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)，從而達到啟閉或調(diào)節(jié)的目的。蝶閥全開到全關(guān)通常是小于90°，蝶閥和蝶桿本身沒有自鎖能力，為了蝶板的定位，要在閥桿上加裝蝸輪減速器。采用蝸輪減速器，不僅可以使蝶板具有自鎖能力，使蝶板停止在任意位置上，還能改善閥門的操作性能。蝶閥處于中開度時，閥體與蝶板前端形成的開口形狀以閥軸為中心，古浪蝶閥銷售廠家，兩側(cè)形成完成不同的狀態(tài)，一側(cè)的蝶板前端順流水方向而動，另一側(cè)</span><span

style="font-size:16px;">原始的蝶閥是一種簡單的，且關(guān)閉不嚴的擋板閥．通常在水管路系統(tǒng)中作為流量調(diào)節(jié)閥和阻尼閥使用。隨著防化學腐蝕的合成橡膠在蝶閥上的應(yīng)用，蝶閥的性能得以提高。由于合成橡膠具有耐腐蝕、抗沖蝕，尺寸穩(wěn)定，回彈性好，易于成形，成本低廉等特點，并可根據(jù)不同的使用要求選擇不同性能的合成橡膠，以滿足蝶閥的使用工況條件，因而被用于制造蝶閥的襯里和彈性閥座。閥座密封圈由軟性T形密封環(huán)兩側(cè)多層不銹鋼片組成。閥板與閥座的密封面為斜圓錐結(jié)構(gòu)，在閥板斜圓錐表面堆焊耐溫、耐蝕合金材料;固定在調(diào)節(jié)環(huán)壓板之間的彈簧與壓板上調(diào)節(jié)螺栓裝配一起的結(jié)構(gòu)。這種結(jié)構(gòu)有效地補償了軸套與閥體之間的公差帶及閥桿在介質(zhì)壓力下的彈性變形，解決了閥門在雙向互換的介質(zhì)輸送過程中存在的密封問題。采用軟性T型兩側(cè)多層不銹鋼片組成密封圈，具有金屬硬密封和軟密封的雙重優(yōu)點，無論在低溫和高溫情況下，均具有零滲漏的密封性能。這也與閥門的質(zhì)量有關(guān)，選擇質(zhì)量的閥門可能</span><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到的，往往是從質(zhì)量可靠的廠方購進組裝。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>
