Numerical Analysis on Delta-Ring Seal Structure of Ultra High Pressure Vessel Employed in Food Processing
Due to the characters of the ultra high pressure vessel employed in food processing, a seal structure was introduced in this study. Then numerical analysis was performed using the larger finite element stress analysis software ANSYS12.0 for the stresses of the seal structure under internal pressure. In order to solve the contact question of delta-ring seal structure by using face-face contact model, 3-D Axisymmetric solid element was employed to calculate the stresses of the connected location among deltaring, blind cover and end cylinder, the contact stresses in this structure was analyzed. The estimation principles of seals were proposed, a good sealing performance should be accorded with these inequations. Thus, the distribution nephogram of the stresses on the contact surface were obtained.
