【Abstract】 CFD software was applied to simulate the thermoshock of three-way valve in the running process in the thermal shock test system,and the Realizable k-ε model was used to analyze the distribution of flow field parameters. The main parts of thermal shock were analyzed by simulation results. In view of the problem of the leakage caused by easy wear,the optimization and improvement scheme was put forward.更多还原
