| Abstract: | To achieve dynamic characteristics of the pressure reducing valve, a dynamic simula- tion model of the converse unloading pressure reducing valve that was usually applied in liquid rocket engine was built. The AMESim method is adopted for simulation. The influence of different factors on dynamic characteristics of the pressure reducing valve is analyzed emphatically. The measures of improving the dynamic characteristics of the pressure reducing valve are proposed. The test results show that the measures are reasonable and feasible. |
