style="font-size:16px;">原始的蝶閥是一種簡單的，且關閉不嚴的擋板閥．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)兩側多層不銹鋼片組成。閥板與閥座的密封面為斜圓錐結構，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)螺栓裝配一起的結構。這種結構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，選擇質(zhì)量的閥門可能</span><span
