摘　　要：针对汽轮机提板式调节汽阀阀碟在机组运行过程中出现的故障,通过理论分析和ANSYS软件三维仿真的手段,对阀碟故障产生的原因进行深入的研究,并提出一种新的阀碟结构,利用三维建模及仿真软件对新结构进行强度分析,结果表明该新结构能够有效解决原结构的强度问题,为此类机组调阀设计提供了新的思路。With respect to the fault occurred in in the valve disc in steam adjusting valve used in turbine,theoretical analysis and 3-D simulation by using ANSYS were performed so as to investigate the cause of the fault.One new disc structure was then presented.Through strength analysis using establishment of 3-D model and simulation,it was shown that the problem existed in old disc structure can be solved from use of new disc structure,which may be referenced in the design of adjusting valve as a new choice.
