Description

Technical Field

[0001] This utility model relates to the field of movable elbow technology, specifically a long-radius high-pressure movable elbow. Background Technology

[0002] High-pressure adjustable elbows are a special type of pipe connector designed to provide an adjustable angle connection in high-pressure environments, ensuring the flexibility and adaptability of piping systems. For example, patent number [patent number missing].

[0003] CN202222260382.4 discloses a long-radius high-pressure movable elbow. This solution improves the elbow's sealing performance by setting a sealing ring between the main high-pressure bend and the auxiliary high-pressure bend. However, since the main and auxiliary high-pressure bends can rotate, the sealing ring experiences significant wear, making it difficult to guarantee the elbow's sealing performance over long-term use. Therefore, relying solely on the sealing ring is insufficient to ensure the sealing effect of the high-pressure movable elbow, which can easily lead to leakage. Furthermore, many high-pressure movable elbows are used with high-temperature fluids, which also affects their lifespan. Therefore, this invention proposes a long-radius high-pressure movable elbow to solve this problem. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a long-radius high-pressure flexible elbow. By setting a first sealing groove and a second sealing groove at the connection section of the main high-pressure elbow, the first sealing groove and the second sealing groove are used for the installation of a sealing ring and a special-shaped sealing ring, respectively. The special-shaped sealing ring cooperates with the sealing protrusion, which can effectively increase the sealing performance of the connection between the connection section and the secondary high-pressure elbow, prevent leakage, and solve the problem of poor sealing performance of the current flexible elbow.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A long-radius high-pressure flexible elbow includes a main high-pressure elbow and a secondary high-pressure elbow. One end of the main high-pressure elbow is integrally formed with a connecting section. A rotating ring is provided between the inner wall of the connecting section and the outer wall of the secondary high-pressure elbow. Two rotating rings are provided. A first sealing groove and a second sealing groove are respectively provided on the side of the connecting section near the secondary high-pressure elbow. A sealing ring is provided at the first sealing groove of the connecting section, and a special-shaped sealing ring is provided at the second sealing groove of the connecting section. A sealing protrusion adapted to the special-shaped sealing ring is fixedly connected to the outer wall of the secondary high-pressure elbow at the location corresponding to the special-shaped sealing ring.

[0009] Furthermore, the irregular sealing ring includes a sealing ring body filling the second sealing groove, and a sealing lip formed on one side of the sealing ring body. An arc-shaped groove is provided between the sealing ring body and the sealing lip. The sealing protrusion includes an arc-shaped sealing part adapted to the arc-shaped groove, and a sealing plate integrally formed on one side of the arc-shaped sealing part. The sealing plate is fixedly connected to the outer wall of the secondary high-pressure bend.

[0010] Furthermore, mounting grooves are provided on the inner wall of the connecting section and the outer wall of the secondary high-pressure bend, and the swivel is positioned at the corresponding mounting groove.

[0011] Furthermore, an annular heat dissipation groove is provided on one side of the outer wall of the connecting section located in the second sealing groove, and an array of heat dissipation protrusions are fixedly connected to the heat dissipation groove of the connecting section.

[0012] Furthermore, both the main high-pressure bend and the auxiliary high-pressure bend have pipe interfaces at their ends furthest from the connecting section.

[0015] Compared with the prior art, this utility model provides a long-radius high-pressure movable elbow, which has the following characteristics:

[0016] Beneficial effects:

[0017] 1. This utility model provides a first sealing groove and a second sealing groove on the connecting section on one side of the main high-pressure bend. The first sealing groove and the second sealing groove are used for the installation of a sealing ring and a special-shaped sealing ring, respectively. The sealing ring contacts the secondary high-pressure bend, and the special-shaped sealing ring contacts and cooperates with the sealing protrusion.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention provides a long-radius high-pressure movable elbow, including a main high-pressure elbow 1 and a secondary high-pressure elbow 3. One end of the main high-pressure elbow 1 is integrally formed with a connecting section 2. A rotating ring 6 is provided between the inner wall of the connecting section 2 and the outer wall of the secondary high-pressure elbow 3. Two rotating rings 6 are provided. A first sealing groove 9 and a second sealing groove 11 are respectively provided on the side of the connecting section 2 near the secondary high-pressure elbow 3. A sealing ring 5 is provided at the first sealing groove 9 of the connecting section 2, and a special-shaped sealing ring 7 is provided at the second sealing groove 11 of the connecting section 2. A sealing protrusion 8 adapted to the special-shaped sealing ring 7 is fixedly connected to the outer wall of the secondary high-pressure elbow 3 at the location corresponding to the special-shaped sealing ring 7.

[0028] It should be noted that the main high-pressure bend 1 and the auxiliary high-pressure bend 3 constitute the main body of the high-pressure movable bend. The auxiliary high-pressure bend 3 can rotate, satisfying the flexibility of the pipeline system. A connecting section 2 is set at one end of the main high-pressure bend 1, which can connect to the auxiliary high-pressure bend 3. A rotating ring 6 is set between the inner wall of the connecting section 2 and the outer wall of the auxiliary high-pressure bend 3, and two rotating rings 6 are set to ensure the stable rotation of the auxiliary high-pressure bend 3. A first sealing groove 9 and a second sealing groove 11 are opened on the connecting section 2. The first sealing groove 9 and the second sealing groove 11 are respectively used for the installation of the sealing ring 5 and the special-shaped sealing ring 7. The sealing ring 5 contacts the auxiliary high-pressure bend 3, and the special-shaped sealing ring 7 contacts the sealing protrusion 8, which can effectively ensure the sealing of the connection between the connecting section 2 and the auxiliary high-pressure bend 3 and prevent fluid leakage. The sealing protrusion 8 has a special shape and is fixed on the auxiliary high-pressure bend 3. The sealing protrusion 8 cooperates with the special-shaped sealing ring 7, which largely ensures the sealing performance of the structure.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the irregular sealing ring 7 includes a sealing ring body 701 filled in the second sealing groove 11, and a sealing lip 703 formed on one side of the sealing ring body 701. An arc-shaped groove 702 is provided between the sealing ring body 701 and the sealing lip 703. The sealing protrusion 8 includes an arc-shaped sealing part 801 adapted to the arc-shaped groove 702, and a sealing plate 802 integrally formed on one side of the arc-shaped sealing part 801. The sealing plate 802 is fixedly connected to the outer wall of the secondary high-pressure bend 3.

[0030] It should be noted that the sealing ring body 701 is the main part of the irregular sealing ring 7, which fills the second sealing groove 11 of the connecting section 2. By setting a sealing lip 703 on one side of the sealing ring body 701, the sealing lip 703 contacts the arc-shaped sealing part 801 and the sealing plate 802, making the connection tighter and the fluid less likely to leak, thus increasing the sealing and protection effect. By setting the irregular sealing ring 7 and the sealing protrusion 8, this utility model can enrich the sealing performance of the movable elbow and increase the safety protection effect.

[0031] like Figure 3 and Figure 4 As shown, in some embodiments, mounting grooves 10 are provided on the inner wall of the connecting section 2 and the outer wall of the secondary high-pressure bend 3, and the swivel ring 6 is disposed at the corresponding mounting groove 10.

[0032] It should be noted that the mounting groove 10 is designed for the installation of the rotating ring 6, which is used for the rotation of the secondary high-pressure bend 3 to achieve angle adjustment of the secondary high-pressure bend 3.

[0033] like Figure 4As shown, in some embodiments, an annular heat dissipation groove 12 is provided on one side of the outer wall of the connecting segment 2 located in the second sealing groove 11, and an array of heat dissipation protrusions 13 are fixedly connected to the heat dissipation groove 12 of the connecting segment 2.

[0034] It should be noted that by opening heat dissipation grooves 12 on the connecting section 2, heat dissipation at the first sealing groove 9 and the second sealing groove 11 is facilitated. Furthermore, heat dissipation protrusions 13 distributed in an array are fixedly connected at the heat dissipation grooves 12 of the connecting section 2, which facilitates effective heat dissipation at the first sealing groove 9 and the second sealing groove 11. This reduces the temperature of the sealing ring 5 and the irregular sealing ring 7, facilitates the dissipation of heat from the sealing ring 5 and the irregular sealing ring 7, and prevents the high temperature of the fluid from affecting the sealing ring 5 and the irregular sealing ring 7.

[0035] like Figure 1 As shown, in some embodiments, the main high-pressure bend 1 and the auxiliary high-pressure bend 3 are both provided with pipe interfaces 4 at the ends away from the connecting section 2, which facilitates connection with external pipe fittings.

[0036] like Figure 3 As shown, in some embodiments, both the sealing ring 5 and the irregular sealing ring 7 are high-temperature resistant sealing components. The high-temperature resistant sealing components are fluororubber seals, which have good high-temperature resistance, thereby extending the service life of the sealing ring 5 and the irregular sealing ring 7.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
