FINITE ELEMENT ANALYSIS OF GATE VALVE

Abstract

Gate valves are used when a straight-line flow of fluid and minimum restriction is desired. Gate valves are so named because the part that either stops or allows flow of fluid through the valve acts somewhat like the opening or closing of a gate and is called, appropriately, the gate. The objective of this paper to perform a stress analysis of the critical component of Gate Valve. The critical components in the Gate Valve are Body, Gate Stem, and slab gate. This paper comprises Finite element analysis of Gate Valve. A model of each element of Gate Valve is developed in CATIA V5R17, and analyzed in ANSYS 11. Gate valve stress analysis is done by FEM using ANSYS 11 and validation is supported by stress analysis using classical theory of mechanics. Finally, the result obtained from FEM software and classical analytical theory are compared.
