Coupling Effect of Temperature Stress in Butterfly Valve Mechanical System Based on FLUENT Numerical Simulation

Abstract:

The butterfly valve system is an important part of the steel heating furnace temperature control. In high temperature, the coupling effect of temperature field and stress deformation of the butterfly valve is stronger. We did not consider it in the numerical simulation research in the past, and studied the overall characteristics of butterfly valve only by 2D numerical simulation, resulting in the decrease of the numerical simulation accuracy. This paper uses the way of the FLUENT software and ANSYS software joint control, and has established the mathematical model of fluid and solid coupling effect, and has implemented the coupling effect of the temperature field and stress field of the butterfly valve system by means of three dimensional numerical simulation, then we have got the temperature distribution and stress distribution of the butterfly valve system, which provides technical reference for mechanical system design of butterfly valve.
