The dynamic characteristic of the flood valve is an important index to ensure its safety and reliability. In this paper, CFD computational fluid dynamics (CFD) method is used to model and simulate the three-dimensional unsteady internal flow field of the valve during its working process, so as to obtain the dynamic distribution of the internal flow field parameters of the valve under specific working conditions. The modal analysis of the valve body is carried out to provide a calculation method and data support for the evaluation of the vibration and noise level during the operation of the valve.
