 對夾襯膠蝶閥,襯膠蝶閥,對夾蝶閥,蝶閥。蝶閥是用閥桿一起轉(zhuǎn)動(dòng)的蝶板作啟閉件，用以實(shí)現(xiàn)閥門的開啟、關(guān)閉與調(diào)節(jié)。蝶閥在管路中除了起切斷和截流用外，近年來已經(jīng)把密封性能作為評價(jià)的主要指標(biāo)，受到市場青睞。另外，蝶閥還有體裁積小、重量輕、結(jié)構(gòu)簡單等優(yōu)點(diǎn)，與同參數(shù)閘閥比較，平均減輕重量達(dá)30~50%，蝶板旋轉(zhuǎn)90度即可實(shí)現(xiàn)啟、閉過程，又由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用力近似相等，轉(zhuǎn)矩相反，因些啟閉力矩較小
