APPLICATIONS OF THE NUMERICAL METHODS IN ANALYZE THE BEHAVIOR OF BIPLANE BUTTERFLY VALVES
The paper presents the elongations obtained by numerical results on a butterfly valve biplane disc by using finite element method and these values were compared with elongations resulted from laboratory tests for three levels of water pressure applied upstream the biplane disc. The comparison between two methods to determine the elongation it shows that the finite element method applied to the disc can replace electrical resistive tensometry, to compute stresses and deformations for biplane butterfly disc on an industrial scale.
