Abstract
Spherical diaphragm seal dish of tube channel open end in high pressure heat exchanger is a new engineering structure that used in petrochemical hydrogenation unit, and its design technology is not reported now. It is inconvenience to analyze each case by limited element method. Design method of formulas is proposed to calculate both radial offset displacement and its thickness of spherical diaphragm based on shell elasticity mechanics. Relation formulas are deduced about arch height, open end radius, offset displacement by geometry. Two presuppositions are deduced for spherical diaphragm successful to run according to technology theory and function analysis of seal dish structure, which can be used for engineering design.
