| Abstract: | Numerical simulation was carried out on high butterfly seat based on the finite element pro- gram -ANSYS when its rip plate in the position of vertical and incline. The stress field of radial, cir- cumferential, axial and MISES equivalent was obtained after analysis. The results show that the maxi- mum equivalent stress on both valve seat occurred at the short tube and the inner wall of the seat tube and the value were 191. 14MPa and 154. 1MPa respectively;The bearing capacity of seat which rip plate is inclined is 1.24 times higher than the other. The results can provide some reference bases of the structure optimization and security selection for high temperature butterfly valve. |
