| Abstract: | Based on the operational principle of the pilot-operated sequence valve,a pilot reversing valve of the pressure differential feedback hydraulic impactor was designed. The simulation model of the valve was built,based on the Matlab/Simulink software, the pressure curves of the front chamber, the back chamber and the pilot valve chamber of the reversing valve,as well as the motion law of the main spool and the pilot valve spool were obtained. The simulation result shows that the valve can work in accordance with the pilot-operated sequence valve mode, and meet the design requirements |
