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
The invention belongs to machinery manufacturing technology field, particularly relate to the wear-resistant seal nut.
Background technique
At present, in main equipment the application of nut very extensive, industrial particularly aviation industry and chemical industry are also more and more higher to the requirement of nut.Simultaneously, along with the requirement of equipment precision is more and more higher, to putting forward more and more higher requirement in performance, parameter and working life of valve, particularly to being applied to containing the nut in the environment such as acid, alkali, salt, high temperature and high concentration of sediment, this higher requirement is arranged, and existing nut, because structure is single, is prone to poor sealing after working long hours, the defects such as the life-span is lower, have a strong impact on like this life-span of equipment and use safety.
Summary of the invention
Technical problem to be solved is to overcome the defect that prior art exists, and a kind of wear-resisting and wear-resistant seal nut that sealing is good is provided.
The technology used in the present invention solution is the wear-resistant seal nut, comprises body, groove, seal ring and wear resistant coating, and the body upper end is provided with groove, and seal ring is arranged in groove, on seal ring inner ring and inner body wall, is coated with wear resistant coating.
Described groove is two ditch grooves, and the thickness of seal ring is greater than depth of groove.
Compared with prior art, the beneficial effect that the present invention has is: 1. the present invention, by nut body and seal ring, applying wear resistant coating, has improved the wear-resisting property of nut;
2. the present invention, by two ditch grooves are set on nut body, has improved the fixed effect of seal ring in nut, has improved to a great extent the sealing of nut.
The accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
In figure:
1, body, 2, groove, 3, seal ring, 4, wear resistant coating
.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the wear-resistant seal nut, comprise body 1, groove 2, seal ring 3 and wear resistant coating 4, body 1 upper end is provided with groove 2, seal ring 3 is arranged in groove 2, on seal ring 3 inner rings and body 1 inwall, is coated with wear resistant coating 4, and wear resistant coating is selected the titanium nitride base intermetallic compound.
Described groove 2 is two ditch grooves, and the thickness of seal ring 3 is greater than groove 2 degree of depth.
