Sažetak
This article presents the dimensioning and 3D modeling of a swing check valve with lever and weight in welded design, based on the existing 2D workshop documentation in cast design and reverse engineering. Based on analytical calculations, pipe wall thickness of a swing check valve housing was selected for the nominal pipe diameter DN 300 and water test pressure p = 2.4 MPa. All 3D models of components, as well as the assembly, were made in the program tool SolidWorks. The 3D model of the swing check valve with flanges was subjected to stress analysis (Finite Element Analysis) for the purpose of checking the accuracy of the analytical calculations. Fluid flow analysis (Flow Simulation) was used for presenting fluid flow process and rate through the swing check valve assembly. A low-budget 3D MakerBot Replicator 2X printer was used for constructing a reduced-scale 3D assembly model of the swing check valve with lever and weight, by implementing the FDM (Fused Deposition Modeling) technology.
