摘要
针对某水电站大型三偏心蝶阀(DN3400)在实际运行过程中出现的问题,利用Abaqus软件对其密封性能进行了分析研究。通过分析结果与传统经验计算以及实际问题的对比分析,证明了分析方法的合理性。改变三偏心蝶阀的三个偏心值,通过大量的仿真实验得到了相应的模拟结果,找到了不同偏心值与密封性能的关系,为提高大型三偏心蝶阀的密封性能提供了理论依据。
In view of the problems about triple eccentric butterfly valve（ DN3400） in actual operation, the sealing performance of valve is analyzed by using Abaqus software. Compared the analysis results with traditional experience calculation and actual problem, the analysis method is proved to be reasonable. Through changing three eccentric values of triple eccentric butterfly valve, a large number of simulation results are obtained and the relationship between different eccentric values and sealing performance is founded. The results provide a theoretical basis for improving the sealing performance of large triple eccentric butterfly valve.
