analysis of a creep deflection of a zinc pressure

ANALYSIS OF A CREEP DEFLECTION OFA ZINC PRESSURE REGULATOR VALVE
PURPOSE: Evaluate the ability of a valve to maintain a seal under long term creep deflection
An FEA model was developed to stimulate a zinc valve under long term creep. Creep properties were obtained from
literature and converted to rational polynomial creep equations for ANSYS. Internal spring forces and uniform
working pressure loads were applied, and critical stresses were checked in the valve body. A long term creep
analysis was conducted under these loads to evaluate the displacements as a function of time, and thus the valves
ability to maintain a seal over time.
