摘要:
利用ANSYS有限元软件建立了烟机入口电液高温蝶阀阀座的实体模型，分析了阀座在厚度为100 mm的保温层条件下的温度场，并采用热结构耦合分析的方法，进一步分析了阀座在高温梯度和内压共同作用下的应力场和变形量.结果表明，阀座筒体的温度沿厚度均匀分布，且内外壁温差仅为1 ℃左右，而保温层的温度沿厚度呈线性递减；阀座筒体的轴向位移较大，最大值为16.72 mm，所承受的等效应力较小，最大值仅为27.7 MPa，满足安全使用要求.
Abstract:
Real model of high temperature electrohydraulic butterfly valve seat at the exit of flue gas turbine was established by finite element software ANSYS. The temperature field of insulating layer with the thickness of 100 mm was analyzed. Stress field and deformation were further obtained by thermal\|structure coupling analysis under high temperature gradient and internal pressure. Results show that temperature through the thickness of the valve tube is well distributed, and the maximum temperature difference between the inner wall and the outer wall of the valve tube is about 1 ℃,moreover, the temperature distribution through the thickness of insulating layer is decreased linearly,the axial displacement of the valve seat can be achieved to 16.72 mm under combined thermal\|mechanical loadings,while the maximum von\|Mises equivalent stress of the valve seat is 27.7 MPa. This indicates the load\|carrying capacity of the high\|temperature butterfly valve meets the requirements of safe application.
