摘要:
为了降低稳态液动力对比例溢流阀性能的影响,分析了阀座带锥角和阀芯带锥角两种比例溢流阀的基本结构方案,利用PRO/E建立两种结构下不同锥角的流道模型.通过计算流体动力学(CFD)流场仿真软件对不同阀座与阀芯锥角的锥阀口流场进行数值模拟,分析不同锥角阀口的压力流场分布.对不同结构、不同锥角情况下的稳态液动力进行分析,结果表明:阀座带锥角比阀芯带锥角的结构稳态液动力减小了35%~60%;当阀座半锥角为32.5°,阀芯半锥角为30°时,稳态液动力最小.
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 simulation 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°.
