Description

Technical Field

[0001] This utility model belongs to the technical field of seamless pipe fittings, specifically relating to a high-strength composite seamless pipe fitting. Background Technology

[0002] Composite seamless pipe fittings are pipe connections manufactured using advanced processes and technologies. Their core feature lies in the optimization of performance and improvement of reliability achieved through a multi-layered composite structure and seamless processing. These fittings are typically made of different metallic or non-metallic materials through a special process. During production, seamless technologies such as hot extrusion, spinning, or precision casting are used to eliminate the weld weaknesses present in traditional welded pipe fittings, making the overall structure of the fitting more uniform and dense. This design not only significantly improves the safety and service life of the fitting under harsh conditions such as high pressure, high temperature, or corrosive media, but also reduces the risk of leakage due to its one-piece molding characteristics. They are widely used in fields with extremely high requirements for pipeline systems, such as petrochemicals, nuclear power, and aerospace.

[0003] However, currently, when laying pipelines, multiple pipelines are usually connected by welding or flanges. Welding is not only more troublesome, but the pipeline cannot be disassembled after welding. Although flange connection can be disassembled, it requires workers to use tools to tighten multiple bolts during installation or disassembly, making it very inconvenient for workers to splice two seamless steel pipes. Utility Model Content

Welding is not only cumbersome, but the pipes cannot be disassembled after welding. Although flange connections can be disassembled, workers need to use tools to tighten multiple bolts during installation or disassembly, making it very inconvenient for workers to splice two seamless steel pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength composite seamless pipe fitting, comprising a pipe fitting and retaining rings disposed at both ends of the pipe fitting;

[0006] A sealing gasket is provided inside one end of the pipe fitting, and a pair of fan-shaped baffles are provided on the inner wall of the pipe fitting.

A slot is provided on the inner side of the upper fixing member and the lower fixing member, and a clamping plate is provided on the inner side of the slot. Multiple springs are provided on the clamping plate.

[0007] Preferably, the retaining ring is welded to the pipe fitting, and the retaining groove between the upper and lower fixing members can be engaged and fixed with the retaining ring. The upper and lower fixing members can restrict and fix the two retaining rings at the pipe fitting connection.

[0008] Preferably, the spring is welded to the clamping plate, and the other end of the spring is welded to the upper and lower fixing parts. The clamping plate can slide in the slot and can clamp the retaining ring from the inside.

[0009] Preferably, the outer rotating component is welded to the lower fixed component, the fixed block is welded to both the upper and lower fixed components, the inner rotating component is welded to the upper fixed component, and the upper fixed component can rotate on the outer rotating component via the inner rotating component.

[0014] 1. By using a retaining ring, upper fixing component, lower fixing component, retaining groove, spring, clamping plate, outer rotating component, inner rotating component, fastening screw, and fixing block, efficient assembly and disassembly of pipe fittings are achieved.

Detailed Implementation

[0022] 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.

[0023] This utility model provides, for example Figure 1-5The high-strength composite seamless pipe fitting shown includes a pipe fitting 1 and retaining rings 5 ​​disposed at both ends of the pipe fitting 1;

[0024] A sealing gasket 6 is provided inside one end of the pipe fitting 1. A pair of fan-shaped baffles 9 are provided on the inner wall of the pipe fitting 1. A limit block 10 is provided at one end of each fan-shaped baffle 9. A clamping groove 13 is provided between the fan-shaped baffle 9 and the sealing gasket 6. A pipe fitting plug 12 is provided at the other end of the pipe fitting 1. A pair of fan-shaped baffles 9 are provided on the outside of the pipe fitting plug 12. An upper fixing member 3 and a lower fixing member 8 are provided on the outside of one end of the pipe fitting 1. An inner rotating member 14 and a fixing block 2 are provided at both ends of the upper fixing member 3. An outer rotating member 7 and a fixing block 2 are provided at both ends of the lower fixing member 8. A slot 15 is provided inside the upper fixing member 3 and the lower fixing member 8. A clamping plate 16 is provided inside the slot 15. Multiple springs 17 are provided on the clamping plate 16.

[0025] In this embodiment, the composite seamless pipe fitting 1 is mainly used in industrial fields with high requirements for pipeline system safety, pressure resistance, and corrosion resistance, such as petrochemical, natural gas transmission, nuclear power engineering, and aerospace. In these scenarios, due to the possibility that the medium may have high pressure, high temperature, or strong corrosiveness, traditional welded pipe fittings 1 are prone to leakage or failure due to weld defects. However, the composite seamless pipe fitting 1, with its multi-layer composite structure and seamless process, can effectively avoid these problems and ensure long-term stable operation. The installation of the composite seamless pipe fitting 1 is similar to that of traditional pipe fittings, usually using flange connection, threaded connection, or direct welding. Before installation, it is necessary to check whether the specifications of the pipe fitting 1 meet the design requirements and ensure that the sealing surface is intact. Since the inner layer of the composite pipe fitting 1 usually has corrosion-resistant or wear-resistant properties, attention should also be paid to the medium flow direction during installation to ensure that the inner layer material plays its best protective role.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the retaining ring 5 is welded to the pipe fitting 1. The retaining groove 15 between the upper fixing member 3 and the lower fixing member 8 can be engaged and fixed with the retaining ring 5. The upper fixing member 3 and the lower fixing member 8 can restrict and fix the two retaining rings 5 ​​at the connection of the pipe fitting 1. The spring 17 is welded to the clamping plate 16. The other end of the spring 17 is welded to the upper fixing member 3 and the lower fixing member 8. The clamping plate 16 can slide in the retaining groove 15. The clamping plate 16 can clamp the retaining ring 5 from the inside. The outer rotating member 7 is welded to the lower fixing member 8. The fixing block 2 is welded to the upper fixing member 3 and the lower fixing member 8 respectively. The inner rotating member 14 is welded to the upper fixing member 3. The upper fixing member 3 can rotate on the outer rotating member 7 through the inner rotating member 14. A fastening screw 4 is provided between the fixing block 2 on the upper fixing member 3 and the lower fixing member 8. The upper fixing member 3 and the lower fixing member 8 are fixed by the cooperation between the fastening screw 4 and the fixing block 2.

[0027] Preferably, the arrangement of the retaining ring 5, upper fixing member 3, lower fixing member 8, retaining groove 15, spring 17, clamping plate 16, outer rotating member 7, inner rotating member 14, fastening screw 4, and fixing block 2 enables quick disassembly and assembly and high-sealing fixation of the pipe fitting 1 connection. The cooperation between the retaining ring 5 and the retaining groove 15 ensures the stability of the two pipe fittings 1 when connected. The elastic cooperation between the spring 17 and the clamping plate 16 can clamp the retaining ring 5 from the inside, making the retaining ring 5 firmly fixed to the upper fixing member 3 and the lower fixing member 8. The upper fixing member 3 can be opened and closed through the rotational cooperation between the inner rotating member 14 and the outer rotating member 7. The fixing block 2 is locked with the fastening screw 4, making the installation process more convenient. Workers do not need to tighten multiple screws, reducing the labor intensity of workers and improving the installation efficiency of the pipe fitting 1. The sealing gasket 6 can seal the connection of the pipe fitting plug 12 to prevent leakage of internal substances of the pipe fitting 1.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the pipe plug 12 is integrally formed with the pipe 1, the fan-shaped locking block 11 is welded to the pipe plug 12, the pipe plug 12 can be inserted into the other end of the pipe 1, the fan-shaped baffle 9 is welded to the inner wall of the pipe 1, the limiting block 10 is welded to the fan-shaped baffle 9, the pipe plug 12 can be rotated to make the fan-shaped locking block 11 engage with the clamping groove 13, and the limiting block 10 can limit the fan-shaped locking block 11.

[0029] Preferably, through the arrangement of the sealing gasket 6, the sector-shaped locking block 11, the sector-shaped baffle 9, the limiting block 10, and the clamping groove 13, the pipe fitting 1 can achieve rapid and accurate insertion and positioning during connection. The cooperation between the sector-shaped locking block 11 and the clamping groove 13 ensures the stability of the connection. At the same time, the sealing gasket 6 effectively improves the sealing performance of the connection of the pipe fitting 1, preventing media leakage. The synergistic effect of the limiting block 10 and the sector-shaped baffle 9 allows the pipe fitting plug 12 to be accurately locked during rotation, preventing the sector-shaped locking block 11 from rotating out of the sector-shaped baffle 9, ensuring unidirectional rotation, avoiding misalignment, and thus enhancing the reliability of the connection between the overall pipe fittings 1. This structural design not only simplifies the installation process but also improves the connection strength of the pipe fittings 1.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
