產(chǎn)品詳情
蝸輪水利法蘭蝶閥：
型號：D341X-16C
一、渦輪蝶閥簡介：
水利法蘭渦輪蝶閥是采用采用金屬密封的閥門一般比彈性密封的閥門壽命長，所以，很難能夠做到完全的密封。渦輪蝶閥的金屬的密封面更能適應較高的工作溫度。蝸輪法蘭水利的蝶閥結(jié)構(gòu)簡單、體積小、重量輕，只由少數(shù)幾個零件組成。不僅如此，而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡單，維護方便，同時該閥門具有良好的流體控制特性。水利渦輪蝶閥處于完全開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時唯一的阻力，因此通過該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。渦輪水利蝶閥如果是要求蝶閥作為流量控制使用。渦輪蝶閥的結(jié)構(gòu)原理是較為適合制作大口徑閥門。渦輪水利蝶閥還應用于熱電站的冷卻水系統(tǒng)。

三、水利渦輪蝶閥工作原理：
水利渦輪蝶閥的金屬密封閥門的設(shè)計是采用三偏心結(jié)構(gòu)原理，利用了固有的凸輪效應，完全消除了90度行程中閥座與密封圈之間的全部摩擦。使閥門啟閉迅速，省力，方便，高效能等特點。
