High-pressure sealing method and sealing ring

Abstract

The invention discloses a method for arranging a shock-absorbing convenient-to-install self-locking nut on a thin-walled plate and a nut assembly. The method is characterized in that one or more than one pressing groove is punched on the external sides of bent parts of a right-angle supporting plate before the right-angle supporting plate is bent, the microstructure of the bent parts of the right-angle supporting plate is enabled to be finer due to the pressing groove, the problems of loose material and internal stress increase caused during the bending of the right-angle supporting plate are reduced, and the material resilience and deformation caused after the right-angle supporting plate is bent can be effectively controlled. The nut assembly comprises the right-angle supporting plate (1) and the self-locking nut (2) which is connected with the right-angle supporting plate (1). One or more than one pressing groove (3) is arranged on the external sides of the bent parts of the right-angle supporting plate (1). By adopting the method, the antifatigue performance is improved and the problem that the self-locking nut cannot be used on thin-walled parts, narrow parts which are hard to approach or non-open structures of airplanes is solved. The method and the nut assembly provided by the invention have the advantages that not only can the manufacturing difficulty of bearing and connecting components be reduced, but also the weight can be reduced, the production process becomes rapid and simple, the safety and the reliability are high and the maintenance is convenient to conduct.

Description

technical field [0001] The invention relates to a high-pressure sealing method and a sealing ring, belonging to the technical field of sealing rings. Background technique [0002] In the design of mechanical parts, there are many types of sealing rings, and the shapes are also different. For some sealing rings with metal rings, the sealing ring and the metal ring are in contact with the circular surface, which is easy to rotate during use and the connection is not firm. Some rubber sealing rings are in line contact with the parts to be connected, such as circular rubber sealing rings, C-shaped rubber sealing rings, V-shaped sealing rings, etc. These rubber sealing ring materials are highly fluid and have a large amount of leakage. And the rubber material is easy to be squeezed into the plane of the metal ring, which will affect the installation stability and sealing performance of the bolt. Especially for sealing rings on high-pressure vessels, ordinary sealing rings are ...

AI Technical Summary

Problems solved by technology

These rubber seal ring materials are highly fluid and have a large leakage

And the rubber material is easy to be squeezed into the plane of the metal ring, which will affect the stability and sealing performance of the bolts.

Especially for the sealing ring on the high-pressure vessel, ordinary sealing rings are often prone to leakage, deformation and failure, etc., causing mechanical failure in severe cases

If it is in rockets, airplanes, high-speed rail and other high-speed vehicles, it is easy to cause accidents and cause great loss of property and life.
