不同锥角的直动式溢流阀稳态液动力分析
Steady-State Flow Force Analysis of the Direct Relief Valve Under Different Cone Angles
摘要
Abstract
In order to reduce the impact of the steady-state flow force on the performance of proportional relief valve, two kinds of basic structures which the seat and the spool with cone angle are analyzed.PRO/E is utilized to build the channel model of these two structures under different cone angles.Computational fluid dynamics (CFD)flow field simula-tion software is employed to simulate the flow field under different seats and spools cone angles and the pressure flow field distribution of the valves under different cone angles is analyzed.The steady-state flow force of different structures and different cone angles are compared.The results show that the steady-state flow force is reduced by 35%-60% when the seat with cone angle compared with the spool with cone angle.And the minimum steady-state flow forces are obtained when the half cone angle of the seat is 32.5°and that of the spool is 30°.关键词
