Description

Technical Field

[0001] This utility model relates to the field of sealing ring equipment technology, specifically a multi-protection sealing ring. Background Technology

[0002] A sealing ring is a sealing component used to prevent the leakage of fluids such as liquids or gases and to prevent the entry of external impurities such as dust and moisture. A multi-protection sealing ring refers to a sealing ring that has multiple protective functions or adopts a multi-layer structure design to provide a more reliable sealing and protection effect.

[0003] However, most of the existing multi-protection sealing rings are composed of ordinary multi-layer sealing rings stacked together. Such multi-protection sealing rings do not have failure protection function when the sealing ring fails during use. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing multi-protection sealing rings are composed of ordinary multi-layer sealing rings stacked together, and such multi-protection sealing rings do not have a failure protection function when the sealing ring fails during use. Therefore, this invention provides a multi-protection sealing ring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-protection sealing ring, comprising: an outer sealing ring one, an inner sealing ring one inserted at one end of the outer sealing ring one, an inner sealing ring two inserted at one end of the inner sealing ring one, an inner sealing ring three inserted at one end of the inner sealing ring two, and an outer sealing ring two inserted at one end of the inner sealing ring three.

The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figure 1 and Figure 2 In this embodiment of the present invention, a multi-protection sealing ring includes: an outer sealing ring 1, an inner sealing ring 2 inserted into one end of the outer sealing ring 1, an inner sealing ring 3 inserted into one end of the inner sealing ring 2, an inner sealing ring 4 inserted into one end of the inner sealing ring 3, and an outer sealing ring 5 inserted into one end of the inner sealing ring 4.

[0023] Reference Figure 3 The outer sealing ring 1 includes an outer sealing ring body 10. An outer ring outer protrusion ring 11 is fixedly provided on the outer side of one end of the outer sealing ring body 10. An outer ring pointed conical protrusion ring 12 is fixedly provided in the middle of one end of the outer sealing ring body 10. An outer ring inner protrusion ring 13 is fixedly provided on the inner side of one end of the outer sealing ring body 10.

[0024] Reference Figure 4 The inner sealing ring 2 includes an inner sealing ring body 20. An inner sealing outer protruding ring 21 is fixedly provided at one end of the outer side of the inner sealing ring body 20. A tapered recessed groove 22 is opened at one end of the inner sealing ring body 20. An inner sealing inner protruding ring 23 is fixedly provided at one end of the inner side of the inner sealing ring body 20. The inner sealing ring 3 4 has the same specifications and model as the inner sealing ring 2.

[0025] Reference Figure 5The inner sealing ring 2 3 includes an inner sealing ring body 2 30. An inner sealing outer protruding ring 31 is fixedly provided at one upper outer end of the inner sealing ring body 2 30. An inner ring pointed conical protruding ring 32 is fixedly provided at one upper middle end of the inner sealing ring body 2 30.

An inner sealing lower inner protruding ring 35 is fixedly provided at one lower outer end of the inner sealing ring body 2 30.

[0026] The above scheme involves stacking the outer sealing ring 1, inner sealing ring 2, inner sealing ring 3, inner sealing ring 4, and outer sealing ring 5 in sequence. This allows the outer ring's pointed conical convex ring 12 to be embedded in the conical recessed groove 22 on one side. The outer ring's outer convex ring 11 and outer ring's inner convex ring 13 are respectively embedded in the outer side of the inner sealing outer convex ring 21 and inner sealing inner convex ring 23 on one side. The inner ring's pointed conical convex ring 32 is embedded in the conical recessed groove 22 on the other side. The inner sealing outer convex ring 31 and inner sealing inner convex ring 33 are embedded in the outer side of the inner sealing outer convex ring 21 and inner sealing inner convex ring 23 on the other side. This achieves a multi-layered protective sealing effect.

[0027] Reference Figure 4 and Figure 5 Two sets of inner sealing outer convex ring 21, conical recessed groove 22, and inner sealing inner convex ring 23 are provided. The two sets of inner sealing outer convex ring 21, conical recessed groove 22, and inner sealing inner convex ring 23 are symmetrically fixed at both ends of the inner sealing ring body 20. Two sets of inner sealing outer convex ring 31, inner ring pointed conical convex ring 32, inner sealing inner convex ring 33, inner sealing lower outer convex ring 34, and inner sealing lower inner convex ring 35 are provided. The two sets of inner sealing outer convex ring 31, inner ring pointed conical convex ring 32, inner sealing inner convex ring 33, inner sealing lower outer convex ring 34, and inner sealing lower inner convex ring 35 are symmetrically fixed at both sides of the inner sealing ring body 20.

[0028] The above scheme involves four sets of inner and outer cavities formed between the two symmetrically arranged inner sealing outer protruding rings 21, 23, 34, and 35. In the event of a single sealing ring failure, the sealed medium entering these four cavities will exert outward pressure on the inner sealing outer protruding ring 21, 23, 34, and 35, thus improving the sealing effect and providing a protective sealing function against sealing failure.

[0029] The working principle of this utility model is as follows: During use, the outer sealing ring 1, inner sealing ring 2, inner sealing ring 3, inner sealing ring 4, and outer sealing ring 5 are stacked sequentially. The outer ring's pointed conical convex ring 12 is embedded into the conical recessed groove 22 on one side. The outer ring's outer convex ring 11 and outer ring's inner convex ring 13 are respectively embedded into the outer sides of the inner sealing outer convex ring 21 and inner sealing inner convex ring 23 on one side. The inner ring's pointed conical convex ring 32 is embedded into the conical recessed groove 22 on the other side. The inner sealing outer convex ring 31 and inner sealing inner convex ring 33 are embedded into the inner sealing outer convex ring 21 and inner sealing inner convex ring 23 on the other side. The outer side of the inner sealing ring 23 achieves a multi-layered protective sealing effect. The symmetrically arranged inner sealing outer ring 21, inner sealing inner ring 23, inner sealing lower outer ring 34, and inner sealing lower inner ring 35 form four sets of inner and outer cavities. In the event of a single sealing ring failure, the sealed medium enters the four sets of inner and outer cavities, creating outward pressure on the inner sealing outer ring 21, inner sealing inner ring 23, inner sealing lower outer ring 34, and inner sealing lower inner ring 35. This enhances the sealing effect and provides a protective sealing function against sealing failure.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
