Simulation and Result Analysis of AMEsim for the Relief Valve Dynamic Characteristics Experiment

For indicators of relief valve´s dynamic characteristics, most important things are both stability and rapid response ability. However, up to the present there is no effective design parameter to satisfy its demand. So, a pilot-operated relief valve and its dynamic experiment system´s simulation model were established, by means of AMEsim software technology. Through the batch parameters simulating show that the dynamic characteristics of the relief valve are affected by the pilot control spool´s diameter size, next is affected by the damper size on the main valve. Further parameter-filtrating and simulating, obtained a satisfactory dynamic curve and design parameters, its response time is 0.05 seconds, work stability, and no pressure overshoot. This measure reproduced the dynamic test methods of relief valve, and played effects of a fast and cost-saving.
