摘　　要：为了指导油气管道调节阀的国产化研发工作,以较低的成本在短期内开发出高质量的产品,采用计算流体动力学(CFD)方法作为辅助手段对调节阀进行优化设计。基于某国产化调节阀的几何结构,建立不同开度下的内部流道,再通过Fluent流场分析软件进行计算,分析调节阀的流通能力、流量特性曲线、斜率偏差以及阀门内部压力和速度的分布情况,以此对调节阀的几何结构进行改进和优化。研究表明:通过CFD方法的优化设计,调节阀在流通能力、流量特性曲线以及斜率偏差等方面都很好地满足了国产化设计需求,达到了节省研发时间及制造和试验成本的目的。To rapidly develop domestic production of low-cost and high-quality regulating valves for oil and gas pipelines, the computational fluid dynamics （CFD） technique is used for optimization to provide references for research and development of regulating valves in China. With consideration to geometric configuration of a domestically produced regulating valve, internal flowing channels under different openness are determined. Then, the Fluent flow-field analysis software is used to analyze flow capacity, flowrate characteristic curves, slope deviations and distribution of internal pressures and velocities in the regulating valve. Based on the research results, geometric configuration of the regulating valve is improved and optimized. Research results show that, due to the CFD-based optimization, flow capacity, flowrate characteristic curves and slope deviations of regulating valves can properly satisfy design demands for domestic production. The technique may effectively reduce the time required for development, together with costs related to fabrication and tests for these regulating valves. （10 Figures, 1 Table, 10 References）
