Problems solved by technology

At the same time, with the higher and higher requirements for equipment precision, higher and higher requirements are put forward for the performance, parameters and service life of valves, especially for environments containing acid, alkali, salt, high temperature and many sediments. The nuts in the device have higher requirements. Due to the single structure of the existing nuts, they are prone to defects such as poor sealing and low life after working for a long time, which seriously affects the life of the equipment and the safety of use.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] like figure 1 As shown, the wear-resistant sealing nut includes a body 1, a groove 2, a sealing ring 3 and a wear-resistant coating 4. The upper end of the body 1 is provided with a groove 2, the sealing ring 3 is arranged in the groove 2, and the inner ring of the sealing ring 3 And the inner wall of the main body 1 is coated with a wear-resistant coating 4, and the wear-resistant coating is made of titanium nitride-based intermetallic compound.

[0013] The groove 2 is a double-groove groove, and the thickness of the sealing ring 3 is greater than the depth of the groove 2 .

Abstract

The invention belongs to the technical field of machining, and in particular relates to an anti-abrasion sealing nut. The anti-abrasion sealing nut comprises a body, grooves, sealing rings and anti-abrasion coating layers, wherein the grooves are formed in the upper end of the body; the sealing rings are arranged in the grooves; and the anti-abrasion coating layers are coated on the inner circles of the sealing rings and the inner wall of the body. The grooves are double-trench grooves; and the thicknesses of the sealing rings are greater than the depths of the grooves. The anti-abrasion coating layers are coated on the nut body and inside the sealing rings, so that the abrasion resistance of the nut is improved; and the double-trench grooves are formed in the nut body, so that an effect of fixing the sealing rings in the nut is enhanced, and the sealing property of the nut is improved to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, in particular to a wear-resistant sealing nut. Background technique [0002] At present, the application of nuts in large-scale equipment has been very extensive, and the industry, especially the aviation industry and the chemical industry, have higher and higher requirements for nuts. At the same time, with the higher and higher requirements for equipment precision, higher and higher requirements are put forward for the performance, parameters and service life of valves, especially for environments containing acid, alkali, salt, high temperature and many sediments. The nuts in the device have higher requirements. Due to the single structure of the existing nuts, they are prone to defects such as poor sealing and low service life after working for a long time, which seriously affects the service life of the equipment and the safety of use.
