Research on Design, Manufacture and Experiment for High-pressure Soft-seated Ball Valve

Abstract

球阀是以球体为开关件的阀门,是阀门中的重要分支。球阀具有流体阻力小、开关迅速方便、密封性好、寿命长、可靠性高等优点。近年来,随着工业对球阀需求的日益增多,对球阀的使用要求也提出了更为苛刻的要求。本文对高压软密封球阀的设计、制造及试验进行了研究:将经验设计,CAD技术和有限元技术相结合,运用到本球阀的设计与优化中;同时对球阀球体密封面加工技术进行了详细的探讨;最后的球阀试验验证了有限元仿真的有效性和球阀优异的使用性能。本文取得的主要成果如下: 设计了一种高压软密封球阀,其操作方便,结构紧凑,同时此球阀通过了静压试验、寿命试验和爆破试验的验证,试验结果表明本文研制的球阀具有优异的使用性能:静压试...The ball valve is an important branch of valve and it is switched by a ball.
