Optimal design and flow resistance analysis of regulating valve spool type line

摘要: 针对传统的调节阀阀芯型线设计无法有效减小压降的问题,采用正交多项式作最小二乘拟合的方法对型线进行优化,得到新的曲线方程,将该方程提取到AutoCAD中设计阀芯型线.数值模拟结果表明,新设计的阀芯型线的流阻系数比原来下降35%,且进出口压降减小,实现了节能的目的.Abstract: In order to solve the problem that type line conventional valve spool design can't effectively reduce pressure drop.Optimization of the profile of the orthogonal polynomials for fitting the least squares method was used to obtain a new curve equation,and then a new curve equation into AutoCAD design type lines was estracted.Numerical simulation results showed that the flow resistance coefficient of the newly designed molded lines decreased by 35% than the original,and import and export reduced pressure dropped,to achieve energy saving purposes.
