Strength Comparison of High Temperature Butterfly Valve Seat in Different Rip Plate Placed

ZHENG Peng;YU Jiu-yang;YE M eng;PENG Hong-yu;Wuhan Institute of Technology;  
Numerical simulation was carried out on high butterfly seat based on the finite element program- ANSYS w hen its rip plate in the position of vertical and incline. The stress field of radial,circumferential,axial and MISES equivalent w as obtained after analysis. The results show that the maximum equivalent stress on both valve seat occurred at the short tube and the inner w all of the seat tube and the value w ere 191. 14MPa and 154. 1MPa respectively; The bearing capacity of seat w hich 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.
