| Abstract: | Based on the analysis platform of element analysis software ANSYS, the model of valve and gas in valve in a certain gas distribution station are established, body thermal stress, natural gas flow field analysis and valve body static and thermal stress analysis are carried out respectively. According to the results of calculation and analysis, this paper finds out the distribution discipline of flow field and thermal stress inside the valve and analyzes safety performance in valve body＇ s weak parts, which provides basis for the reliability evaluation of the valve body. |
