style="font-size:16px;">不銹鋼蝶閥這種蝶閥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(shí)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。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，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>
