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.
