煤化工专用黑水阀阀座流通性能研究

Special black coal chemical properties ofthe flow valve seat

介绍了一种煤化工专用黑水阀的结构构成,并提出进行该型号阀门流通性能研究的重要性。建立流道三维模型,应用CFD有限元分析软件,模拟黑水阀内部流场分布情况,分析可视化结果,确定阀座/阀芯易损位置。分别对不同阀座渐扩角时模型进行仿真模拟,得到阀门进、出口压力值,并依此计算Cv值大小,拟合流量系数曲线,提出阀门在实现最大介质流通时阀座渐扩角范围,为阀门设计提供重要的理论参考。

A special blackwater valve＇s structure is Introduced, and puts forward the importance of this type valve flow performance study. The 3D model is established, useing finite element analysis of CFD soft-ware, to simulate the blackwater valve＇s interior flow field distribution of visualization result analysis, deter-mine the seat/valve core vulnerable position. And Simulate to different seat when the divergent Angle model for simulation, get the inlet and outlet pressure value, and Cv value is calculated based on the data, Cv curve is fited, determine the best seat divergent Angle range, provide important theoretic reference for valve design.
