The CFD analysis of main valve flow field and structural optimization for double-nozzle flapper servo valve

Zhi-fei Peng, Chungeng Sun, Ruibo Yuan, Peng Zhang

Abstract

This paper uses INVENTER software to establish the model of main valve and the servo valve is simulated by FLUENT software. Then, the flow field model of the main valve spool on certain position is established and the possible effects on the hydraulic valve are analyzed due to the shape of the flow field. Finally, we make some improvement of the main valve core, and give some conclusions by comparing the flow field characteristics of main valve with the unimproved valve.
