Problems solved by technology

However, through the analysis of the faulty parts, it can be clarified that the local extrusion deformation of the sealing ring in the sealing structure is large, the local abnormal wear of the contact surface of the sealing ring and the resulting torsional deformation and tearing of the sealing ring are the most important factors causing the failure

Abstract

A structure of a rubber sealing ring radial sealing connector with an automatic centering section is characterized by comprising an unthreaded hole lining connector, a rubber sealing ring, a cap nut and a flat-end connecting mouth with a sealing ring groove. The structure of the rubber sealing ring radial sealing connector with the automatic centering section realizes sealing through extrusion deformation of the rubber sealing ring installed on the flat-end connecting mouth with the sealing ring groove after installation of the rubber sealing ring. The unthreaded hole lining connector and theflat-end connecting mouth with the sealing ring groove are axially connected through the cap nut. The structure of the rubber sealing ring radial sealing connector with the automatic centering sectionhas the advantages of effectively realizing the automatic centering function of connector matching, lowering non-uniform deformation of the sealing ring and touch abrasion of the sealing surface of the connector, lowering torsion and tearing faults caused by fretting wear accumulation generated by large partial deformation after long-time use of the rubber sealing ring, and improving the use reliability of the sealing structure.

Description

technical field [0001] The invention relates to the field of sealing structures, in particular to a structure of a radial sealing joint of a rubber sealing ring with an automatic centering section. Background technique [0002] The radial seal form of the rubber seal ring is a typical surface seal structure with strong adaptability and can be applied in hydraulic systems, fuel systems and lubricating oil systems with low pressure and temperature. Therefore, this seal form is widely used in aviation, aerospace and civil applications Hydraulic equipment and other fields. [0003] Oil leakage failures of the sealing structure often occur during field use, and there are many factors that cause oil leakage failures of rubber sealing rings, which are difficult to analyze and deal with. However, through the analysis of the faulty parts, it can be clarified that the local extrusion deformation of the sealing ring in the sealing structure is large, the local abnormal wear of the con...
