Abstract :
This paper based on the flow field numerical simulation method to analyze the valves used for space instrumentation ,the flow field of high-pressure unloading valve was numerical simulation upon different structural parameters,thus it achieved the result of the pressure and velocity field. the effect of flow field and pressure velocity characteristic by the structural parameters was analyzed. The results of the numerical simulation was verified by the experimental test,so the results provided some references for the unloading valve optimum structure design and performance improvement.
