style="font-size:16px;">閘閥（gatevalve）是一個(gè)啟閉件閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，閘閥只能作全開(kāi)和全關(guān)，不適門(mén)參數(shù)而異,通常為5°,介質(zhì)溫度不高時(shí)為2°52‘。改善其工藝性,彌補(bǔ)密封面角度在加工過(guò)程中產(chǎn)生的偏差,這種閘板叫做彈性閘板。使用工況和介質(zhì)：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、建筑給排水等工程系統(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?cái)嘟橘|(zhì)的流動(dòng)。閘閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來(lái)密封，即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制密封的，即閥門(mén)關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座，以保證密封面的密封性。</span> </p><p> <span style="font-size:16px;">不銹鋼蝶閥這種蝶閥在使用過(guò)程中仍然存在以下問(wèn)題：一、由于多層軟硬疊式密封圈固定在閥板上，當(dāng)閥板常開(kāi)狀態(tài)時(shí)介質(zhì)對(duì)其密封面形成正面沖刷，金屬片夾層中的軟密封帶受沖刷后，直接影響密封性能。二、受結(jié)構(gòu)條件的限制該結(jié)構(gòu)不適應(yīng)做通徑DN200以下閥門(mén)，原因是閥板整體結(jié)構(gòu)太厚，流阻大。三、因三偏心結(jié)構(gòu)的原理，閥板的密封面與閥座之間的密封是靠傳動(dòng)裝置的力矩使閥板壓向閥座。正流狀態(tài)時(shí)，介質(zhì)壓力越高密封擠壓越緊。當(dāng)流道介質(zhì)逆流時(shí)隨著介質(zhì)壓力的增大閥板與閥座之間的單位正壓力小于介質(zhì)壓強(qiáng)時(shí)，密封開(kāi)始泄漏。高性能三偏心雙向硬密封蝶閥，其特征在于：所述閥座密封圈由軟性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)。</span>
