Stress Analysis of Ultra-Supercritical and Electrical Three-Way Valve Body Intensity in a High Pressure Heater Using FEM

Abstract:

Temperature and thermo-mechanical coupling stress distributions of the electrical three-way valve body in a high pressure heater are investigated by using finite element method analysis. Maximum stress at the outer wall region of the valve body has exceed the allowable stress of the material is obtained. The weak place is improved by increasing the wall thickness and the stress meet the requirement of the allowable stress of the material after FEM analysis. And the thermo-mechanical coupling stress are classified and evaluated in the most dangerous section. The evaluation results show that the various types of stress all meet intensity requirements, which provide a guideline for the design and optimization of the high temperature and high pressure valve in the future.
