Implementation method of pressure self-tightening sealing structure

Abstract

The invention discloses a parameterization design method of a pressure self-tightening sealing structure, which comprises the following steps: firstly, creating a two-dimensional geometric model of the pressure self-tightening sealing structure by using CAD software, and determining a geometric relationship among a valve body 1, a stuffing box 2, a four-opening ring 3, a gasket 4 and a sealing ring 5 in the pressure self-tightening sealing structure; secondly, obtaining geometric parameters of the pressure self-tightening sealing structure, and determining basic parameters and driving parameters of parameterized design; finally, adding basic parameters and driving parameters into an EXCEL software interface, writing a function relation between the basic parameters and the driving parameters, and forming a parameterized design program of the pressure self-tightening sealing structure. According to the invention, rapid design of the pressure self-tightening sealing structure is achieved, the design efficiency is improved, the design accuracy is improved, and the superiority of the method is embodied.

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...
