Abstract

The utility model discloses a metal sealing ring, and aims to provide a metal sealing ring with the sealing performance improved and the service life prolonged. According to the technical scheme of the metal sealing ring, the metal sealing ring is characterized in that the end faces are respectively provided with a sealing part, each sealing part comprises a plurality of sealing loops and a sealing end face formed by the sealing loops, each sealing end face is a conical face, and the sealing ring body is provided with an abrasion-resistant and corrosion-resistant coating in a thermal spraying mode. The sealing loops tightly abut against and make contact with sealing positions to generate sealing performance, and the sealing performance is not affected by working environment, abrasion of the sealing loops and ageing of materials. Two-way sealing can be achieved by the two sealing end faces, and the sealing performance of the metal sealing loops is more favorable for being improved. The most protruding sealing loops tightly abut against and make contact with the sealing positions through the conical sealing end faces, and after the most protruding sealing loops are abraded, the second protruding sealing loops, the third protruding sealing loops and the like sequentially replace the sealing loops having been abraded before for sealing. The coating arranged on the sealing ring body in the hot spraying mode has the various functions of anti-corrosion, anti-abrasion and the like.

Description

Metal o-ring

Technical field

The utility model relates to a kind of seal ring, and more particularly, it relates to a kind of metal o-ring.

Background technique

In the use of industrial production and a lot of products, seal ring has become an indispensable part, the existence of seal ring can be so that there be good barriers function interiors of products and outside, guarantee the stable of product performance, but current seal ring all adopts rubber material to make, in the working environments such as high temperature, high pressure and deep-etching, due to long-term excessive compression, will make rubber lose elasticity, easily aging, there will be the phenomenons such as seal ring is extruded, swelling, affect sealing effect, obviously cannot meet the usage requirement of mechanical seal long lifetime.

Metal o-ring can meet the use under the conditions such as high temperature, high pressure and deep-etching, but this metal o-ring is arranged in machinery, the contacting point of metal o-ring is the rigid contact of metal, has so directly affected the sealing effect of metal o-ring, and sealing is not ideal enough.

Model utility content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of raising sealing, the metal o-ring increasing the service life.

For achieving the above object, the utility model provides following technological scheme: a kind of metal o-ring, the seal ring body that comprises metal material, seal ring body comprises the end face at upper and lower two ends, described end face is equipped with sealed department, the seal face that described sealed department includes some seal rings and consists of some seal rings, and described seal ring and seal ring body coaxially arrange, described seal face is the conical surface, and described seal ring calor innatus is coated with resistance to wears and corrosion resistant coating.

Described seal ring and seal ring body are structure as a whole.

Described seal ring is evenly distributed in sealed department.

Described seal ring cross section is dentation, at the bottom of sealing ring includes tooth top and tooth, at the bottom of described tooth top and tooth, is rounding.

A kind of metal o-ring, the seal ring body that comprises metal material, seal ring body comprises the end face at upper and lower two ends, described end face is equipped with sealed department, the seal face that described sealed department includes some seal rings and consists of some seal rings, described seal ring and seal ring body coaxially arrange, and described seal face is the conical surface, and described seal ring calor innatus is coated with resistance to wears and corrosion resistant coating.By adopting technique scheme, when using metal o-ring, seal face is being subject to after axial force, seal ring just with the sealing place generation sealing of closely conflicting, and sealing is not subject to the wearing and tearing of working environment and seal ring and the impact of material ageing, makes good sealing effect.And the two ends of seal ring body are equipped with seal face, two seal faces can be realized two way sealed, are more conducive to improve the sealing of metal o-ring.The seal face that is the conical surface can closely be conflicted seal ring and sealing place of protruding most, realize the sealing of line style, when the seal ring protruding most exists after wearing and tearing, before the second seal ring protruding, the 3rd seal ring protruding etc. will replace successively, the seal ring of wearing and tearing seals, have simple in structure, cost is low, functional reliability high.The coating of thermal spraying on seal ring body can have: anticorrosion, wear-resisting, high temperature resistance, anti-oxidant, heat insulation etc. is several functions, has extended the working life of metal o-ring, has expanded the using scope of metal o-ring.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the utility model metal o-ring embodiment is described further.

A kind of metal o-ring, the seal ring body 1 that comprises metal material, seal ring body 1 comprises the end face at upper and lower two ends, described end face is equipped with sealed department 2, the seal face 4 that described sealed department 2 includes some seal rings 3 and consists of some seal rings 3, described seal ring 3 coaxially arranges with seal ring body 1, and described seal face 4 is the conical surface, and described seal ring body 1 thermal spraying has resistance to wears and corrosion resistant coating.When using metal o-ring, seal face 4 is being subject to after axial force, seal ring 3 just with the sealing place generation sealing of closely conflicting, and sealing is not subject to the wearing and tearing of working environment and seal ring and the impact of material ageing, makes good sealing effect.And the two ends of seal ring body 1 are equipped with 4, two seal faces 4 of seal face can realize two way sealed, is more conducive to improve the sealing of metal o-ring.The seal face 4 that is the conical surface can closely be conflicted the seal ring 3 protruding most with sealing place, realize the sealing of line style, when the seal ring 3 protruding most exists after wearing and tearing, before the second seal ring 3 protruding, the 3rd seal ring 3 protruding etc. will replace successively, the seal ring 3 of wearing and tearing seals, have simple in structure, cost is low, functional reliability high.As shown in Figure 2, when the conical surface of seal face 4 is convex, the seal ring 3 of innermost circle protrudes most; As shown in Figure IV, when the conical surface of seal face 4 is spill, the seal ring 3 of outmost turns protrudes most; Also structure that can be as shown in Figure 5,4 one of the seal faces of metal o-ring are concave conical surface, and one is the convex conical surface, and this structure has the sealing of more stable more balance.The coating of thermal spraying on seal ring body 1 can have: anticorrosion, wear-resisting, high temperature resistance, anti-oxidant, heat insulation etc. is several functions, has extended the working life of metal o-ring, has expanded the using scope of metal o-ring.

Described seal ring 3 is structure as a whole with seal ring body 1.The metal o-ring of integrative-structure does not connect gap, has effectively avoided internal leakage, and prevents that seal ring 3 and seal ring body 1 are inhomogeneous because of the sealing that the inclined to one side mistake of concentricity causes, and has further increased the sealability of metal o-ring.

Described seal ring 3 is evenly distributed in sealed department 2.The seal ring 3 being evenly distributed in sealed department 2 can be realized the uniformity that metal o-ring seals, and is conducive to improve the sealing of metal o-ring.

Described seal ring 3 cross sections are dentation, and sealing ring 3 includes at the bottom of tooth top 31 and tooth 32, and at the bottom of described tooth top 31 and tooth, 32 are rounding.At the bottom of tooth top 31 and tooth, 32 are doing the working life that can improve metal o-ring after rounding is processed.
