Abstract:
In order to prevent the damage of pressure oscillation on the sealing area of valve core, a pressure reducing valve in attitude control engine system was studied on the outlet pressure oscillation during start-up process and inhibition approaches.Based on AMESim simulation platform, a simulation model of PRV was established to analyze the influence of valve spool opening degree and orifice on the starting characteristics.The simulation results show that adding orifice and reducing spool opening degree are beneficial to suppress the pressure oscillation during start-up process.Therefore, the valve spool opening degree is optimized and the flow limiting ring is added at the inlet.The test results indicate that the outlet pressure of the improved PRV is relatively stable and the oscillation phenomenon is effectively suppressed.
