油煤浆调节阀扭矩数值模拟分析

Simulation Analysis of Coal-Oil Slurry Control Valve Torque

介绍了应用CFX软件对油煤浆调节阀流道进行数值模拟仿真和扭矩计算,并将计算的扭矩数值拟合成关于压差和开度函数关系,简化了调节阀扭矩的计算方法。

In order to simplify the control valve torque calculation process,through the coal oil slurry regulating valve mechanism analysis and using CFX software to do the numerical simulation analysis of the flow channel,calculate the size of the valve torque. The calculated torque value fitted on the pressure and the opening of a function,which is a new idea for calculating the size of the valve torque.
