Abstract

The invention discloses a high-pressure air joint with insulating, wear-resistant and corrosion-resistant nano coating and a preparation method of the high-pressure air joint. The high-pressure air joint comprises a screw-in joint and a square shoulder joint which are connected by means of outer sleeve nuts, wherein the inner surfaces of the screw-in joint and the square shoulder joint are coatedwith a zirconium oxide thermal insulation insulating layer and a composite material layer. According to the high-pressure air joint, the protective layer formed by compounding the nanometer materialsis arranged on the inner surface of the joint, so that the air joint has high abrasion resistance and corrosion resistance, meanwhile, the protective layer can achieve the effects of thermal insulation and electric insulation, the application range of the air joint is widened, the universality is improved, and the defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a high-pressure air joint with an insulating, wear-resistant and anti-corrosion nano-coating and a preparation method thereof. Background technique [0002] The high-pressure air joint is an important part of the high-pressure air pipeline, which plays the role of connecting equipment, system pipelines and changing the direction of the medium. [0003] Chinese patent CN105387301A discloses a compressed air fast pipe joint, including a joint pipe and a gland, the inner ring of the right end of the gland is provided with an annular protruding ring, and the inner ring of the gland on the left side of the annular protruding ring is provided with an annular inclined wall , the inner side of the annular inclined wall is provided with a pusher, the left side of the pusher is offset against the right end of the joint pipe, and the right outer wall of the pusher is adapted to ...
