| Abstract: | By using a finite element analytic method,simulated and analyzed was a steam turbine bypass valve in a 330 MW power plant.Under the off-design and rated load operating regimes,the temperature and stress field of the valve body were analyzed.Therefore,the law governing the change of the temperature field and its corresponding stress field at different operating regimes was obtained.Among these operating regimes,the temperature gradient at the inlet of the valve body attains the maximum value under the off-de... |
