计算流体力学在控制阀故障分析及结构改进上的应用

Application of computational fluid dynamics in analysis on trouble shooting of control valve and design optimization

以真实案例为例,利用计算流体力学软件对问题阀芯进行受力分析,发现了阀门振动的原因,并通过对仿真矢量图的分析指出了结构改进的方向。分析证明,新结构的受力情况得到明显改善,展示了计算流体力学在阀门故障分析和结构改进中的应用。

By analyzing the force on the plug in a real field case,the reason for vibration of control valve is found.The direction of optimizing the control valve structure is clear through the analysis on the vectors. The analysis results show that the force on the plug is obviously improved. It suggests that CFD is a helpful tool for analysis of the trouble shooting issue of control valves and design optimization.
