電動法蘭蝶閥被廣泛地應用到介質溫度≤550℃的冶金、電力、石油、化工、空氣、煤氣、可燃氣體以及給排水等腐蝕性介質的管道上,該蝶閥采用一個“U”型不銹鋼密封圈,該精密的彈性密封圈與經過拋光的蝶板三維偏心接觸。解決了傳統偏心蝶閥在啟閉0°~10°瞬間密封面仍處于滑動接觸摩擦的弊病,實現蝶板在開啟瞬間密封面即分離,關閉接觸即密封的效果,達到延長使用壽命、密封性能**的目的。
特點
1、該蝶閥結構簡單、緊湊、重量輕、易于安裝和拆卸、維修方便;
2、本蝶閥采用不銹鋼“U”型密封圈,具有一定的彈性無論在高溫、低溫的情況下,它與蝶板均具有優良的密封性;
3、本蝶閥的三維偏心距,經過嚴格的計算,“U”型密封圈與蝶板幾乎無磨擦,使用壽命長,并具有越關越緊的功能;
4、蝶板密封面采用堆焊鈷基硬質合金,密封面耐磨損,使用壽命長;
5、本蝶閥結構獨特,“開關”僅需轉動閥桿90°即可完成。操作靈活、方便、省力、不受介質壓力的高低影響,密封性能可靠;
6、耐高溫、耐低溫、耐腐蝕性。
