Hydrodynamic behaviour improvement of check valves through CFD analysis

Abstract

In this article, the computer assisted design, flow simulation, optimization of production parameters and unique design prototype manufacturing of a check valve with 16 bar pressure, 5 m/s flow rate and 52000 m3/h flow coefficients, which have never been achieved before in the valve sector, were presented to the attention of the readers. Check valves have a critical role that do not allow reverse flow of the fluid passing through them and are generally designed to secure the pipeline. A small mistake in design may cause great damage in the system. For this reason, a new product of which the disc material exposed to 5 m/s fluid velocity, the body subjected to 16 bar pressure and the system with a flow coefficient of 52000 m3/h were designed by the Solidworks, the flow was simulated with CFD (Computational Fluid Dynamics), and the mechanical resistance was analysed by FEA (Finite Element Analysis). Fluent, CFD and mechanical modules of ANSYS were used to define the parameters of the design. The manufactures of the products designed in the computer environment have been produced by casting method with a 45% ferritic microstructure and impact resistance twice as high as the standard requirements have been implemented.
