| Summary: | In view of the problem that the static characteristics of the slide valve can affect the performance of the hydraulic servo system，the software simulation method is mainly used to analyze the pressure，flow velocity and flow distribution law of the internal flow field of the spool with the change of the spool displacement when the improved rectangular pre opening is set at the spool shoulder of the slide valve，so as to obtain the strain of the spool and the change law of the pressure and flow velocity on different flow surfaces. The distribution of pressure，flow velocity，flow rate and other parameters without pre opening are simulated and analyzed，and the influence of rectangular pre opening and no pre opening on the flow gain of hydraulic valve is analyzed．The simulation results show that the improved rectangular groove structure can significantly improve the internal flow field distribution ，effectively reduce the spool deformation，and improve the dynamic and static performance of the directional valve. |
