Anti-corrosion sealing element structure

Abstract

The invention relates to the technical field of sealing elements, in particular to an anti-corrosion sealing element structure. The anti-corrosion sealing element structure comprises an elastic rubbersealing sleeve and a sealing fixing piece, wherein the elastic rubber sealing sleeve is arranged at the joint of two thick-wall pipelines, and the sealing fixing piece is arranged on the outer peripheral side of the sealing sleeve; the sealing fixing piece comprises a plurality of arc-shaped fixing pieces arranged around the outer periphery of the sealing sleeve in an arrangement mode, and magnetic absorption layers are arranged on the axial sides of the fixing pieces, and the other axial sides of the fixing pieces are provided with magnetic attraction butt joint layers connected with the magnetic absorption layers of the adjacent fixing pieces; and connecting ends I are arranged at the axial ends of the thick-wall pipelines, and the other axial ends of the thick-wall pipelines are provided with connecting ends II which are in butt joint with the connecting ends I of the adjacent thick-wall pipelines; the inner surface of the sealing sleeve is provided with a layer of nano-compositecoating, and the nano-composite coating is formed by compounding a nano material and an organic coating. According to the structure, the connecting sealing effect of the pipelines can be greatly improved through specific structures of the pipelines and the combination of the sealing sleeve and the sealing fixing piece, and the connection between the two pipelines is facilitated, and the corrosionresistance is good.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to an anti-corrosion seal structure. Background technique [0002] Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from intruding into the internal parts of machinery or pipes. Although the seal is small, its function makes it a basic component and accessory in the main industries of the national economy such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing, and occupies a very important position in the development of the national economy. The ordinary seal is an O-ring, which is mostly used in the groove of the junction of machinery and pipelines. It enters the groove by extrusion to closely contact the machinery or pipeline to play a sealing role. However, the seal of this structure is not compatible with machinery ...

AI Technical Summary

Problems solved by technology

The ordinary seal is an O-ring, which is mostly used in the groove of the junction of machinery and pipelines. It enters the groove by extrusion to closely contact the machinery or pipeline to play a sealing role. However, the seal of this structure is not compatible with machinery and pipelines. The contact tightness is poor, the contact part is prone to gaps, resulting in gas or liquid leakage, and the sealing effect is poor

[0003] For pipes with thicker pipe walls, they are usually connected by threads, but due to the large volume and weight of the pipes, it is inconvenient to rotate when connecting, so the connection is very inconvenient and the sealing effect is poor after connection

Moreover, the wide application of rubber seals requires them to be in contact with acid-base and highly oxidizing substances in many occasions, which requires high corrosion resistance and oxidation resistance. Currently, rubber components containing halogens are often used to process seals , but it will cause the problem of refractory degradation, and the existence of a large number of halogens will cause serious pollution to the environment
