Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a method for realizing a pressure self-tightening sealing structure. Background technique [0002] At present, most of the traditional pressure self-tightening sealing structures rely on the friction between parts to achieve self-tightening. Its defect is that it relies too much on human experience, and can only make qualitative judgments that self-tightening can be realized, but cannot quantitatively calculate the degree of self-tightening. The existing technology also has a certain degree of calculation process, but it has the defects of long design cycle, cumbersome design calculation, and prone to errors in the design process. Contents of the invention [0003] The purpose of the present invention is to provide a parametric design method of a pressure self-tightening sealing structure, so as to improve the design efficiency of the pressure self-tightening sealin...
