英文摘要	Aiming at the strength destruction of high temperature and high pressure valve in the normal condition, an ultra-supercritical steam trap was taken as the research object, the fluid-solid-heat coupling simulation was carried, and the distributions of the fluid pressure and velocity were obtained, the distributions of the whole valve temperature field, the stress and deformation were also obtained. The results show that the valve will not produce cavitation after the depressurizing of multilevel sleeve step by step, and the flow rate is controlled; the maximum stress is found on the connection of the upper sleeve and the gland, the thermal stress values on the import and export of the valve are larger, and according to the stress classification and assessing criterion, they all meet the requirements of strength. It can provide reference for the design and optimization of the high temperature and high pressure valve. © (2014) Trans Tech Publications, Switzerland.
