摘要
探讨了三偏心蝶阀密封圈受力不均匀的问题,介绍了四偏心蝶阀结构及四偏心原理,分析了四偏心蝶阀密封圈的压力分布形态及特点,给出了高温高压工况使用时蝶阀零件强度的计算公式。
The paper explores the uneven force on the sealing ring of the tri-eccentric butterfly valve,introduces the structure of the quadruple-eccentric butterfly valve and its principle,analyzes the pressure distribution pattern and its charactoristics on the sealing ring of the quadruple eccentric butterfly valve,also comes up with the formula for parts' strength for high pressure and temperature.
