<span style="font-size:16px;">閘閥（gatevalve）是一個啟閉件閘板，閘板的運(yùn)動方向與流體方向相垂直，閘閥只能作全開和全關(guān)，不適門參數(shù)而異,通常為5°,介質(zhì)溫度不高時為2°52‘。改善其工藝性,彌補(bǔ)密封面角度在加工過程中產(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。閘閥關(guān)閉時，密封面可以只依靠介質(zhì)壓力來密封，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，即閥門關(guān)閉時，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;">有一種比較先進(jìn)的蝶閥是三偏心金屬硬密封蝶閥，閥體和閥座為連體構(gòu)件，閥座密封表面層堆焊耐溫、耐蝕合金材料。多層軟疊式密封圈固定在閥板上，這種蝶閥與傳統(tǒng)蝶閥相比具有耐高溫，操作輕便，啟閉無磨擦，關(guān)閉時隨著傳動機(jī)構(gòu)的力矩增大來補(bǔ)償密封，提高了蝶閥的密封性能及延長使用壽命的優(yōu)點(diǎn)。但是，通過對德國ARCA蝶閥的研究發(fā)現(xiàn)在使用過程中仍然存在以下問題：一、由于多層軟硬疊式密封圈固定在閥板上，當(dāng)閥板常開狀態(tài)時介質(zhì)對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。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，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裝置的力矩使閥板壓向閥座。正流狀態(tài)時，介質(zhì)壓力越高密封擠壓越緊。當(dāng)流道介質(zhì)逆流時隨著介質(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，密封開始泄漏。</span>
