Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a large-scale bidirectional pipeline connection assembly. Background Technology

[0002] According to Chinese Patent No. CN222334749U, this utility model applies to the field of pipeline connection technology and provides a highly applicable and stable pipeline connection component, including a main connecting pipe and two locking clamps. The two locking clamps are used to lock onto two pipes to be connected from both sides. The two pipes to be connected pass through the locking clamps from both sides and extend into the main connecting pipe, which provides a seal. The main connecting pipe includes a connecting cylinder with two insertion cavities on either side. Multiple unit locking plates are movably inserted around the insertion cavities, and inclined surfaces are provided at the ends of the unit locking plates. When a medium flows in the pipe, the medium flow pushes the inclined surfaces forward, and the inclined surfaces push the unit locking plates upward, causing the unit locking plates to press more firmly against the pipe ends, ensuring a stable seal between the insertion cavities and the pipe ends. With continuous medium flow, a stable and continuous seal between the insertion cavities and the pipe ends is achieved.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] 1. Existing large-scale pipeline connection methods have some shortcomings. The sealing performance of the connection structure is poor, which can easily lead to fluid leakage, resulting in not only a waste of resources but also a potential safety accident. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a large-scale bidirectional pipe connection assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a large-scale bidirectional pipe connection assembly, comprising a first connecting pipe body, an annular sealing groove on one side of the first connecting pipe body, a second positioning flange on the surface of the first connecting pipe body, a positioning bolt inside the second positioning flange, a second connecting pipe body on one side of the first connecting pipe body, a first positioning flange on the surface of the second connecting pipe body, and an annular boss on one side of the second connecting pipe body.

[0007] Preferably, one end of the annular sealing groove is provided with an elastic sealing ring, and the elastic sealing ring is positioned and connected to the elastic sealing ring.

[0008] Preferably, one side of the first connecting pipe body is provided with an external thread, and the external thread is welded to one end of the first connecting pipe body.

[0009] Preferably, the inner surface of the second connecting tube is provided with an internal thread, and the internal thread is removed by scanning.

[0010] Preferably, the top of the second positioning flange is provided with a first clamp, and the first clamp and the second positioning flange are fitted together.

[0011] Preferably, a fastening threaded bolt is provided on one side of the first clamp, and the fastening threaded bolt is threadedly connected to the first clamp.

[0012] Preferably, the bottom of the first clamp is provided with a second clamp, and the second clamp is threadedly connected to the first clamp by a fastening threaded bolt.

[0013] Beneficial effects

[0014] In this invention, an annular sealing groove is provided on one side of the first connecting pipe body, and an elastic sealing ring is provided at one end of the annular sealing groove. The design of the annular sealing groove provides a precise installation position for the elastic sealing ring, enabling it to stably perform its sealing function. The elasticity of the elastic sealing ring itself allows it to fit tightly against the inner wall of the pipe during connection, filling any gaps and forming the first line of defense for sealing. Moreover, the cooperation between the annular sealing groove and the elastic sealing ring is equivalent to constructing a double sealing structure, greatly enhancing the sealing effect and effectively preventing leakage of fluid media in the pipe. The elastic sealing ring can automatically adjust its sealing state according to changes in pressure inside the pipe and slight deformation of the pipe.

[0015] In this invention, a first clamp is located at the top of the second positioning flange, with a fastening threaded bolt on one side of the first clamp and a second clamp at the bottom. The combined structure of the first and second clamps tightens the pipeline from two directions, firmly fixing it to the positioning flange and effectively preventing loosening or detachment during operation. For large pipelines, which are subject to significant weight and pressure, this clamp structure provides sufficient clamping force to ensure the stability of the pipeline connection. The fastening threaded bolt allows for adjustment of the clamp's tightness according to actual needs. During installation, workers can adjust the clamp's gripping force by tightening or loosening the threaded bolt to accommodate different pipeline materials.

[0016] In this invention, the first connecting pipe body has an external thread on one side, and the inner surface of the second connecting pipe body has an internal thread. This allows for initial positioning of the two pipes during installation. The external and internal threads engage with each other, achieving multi-turn meshing. During tightening, the friction and engagement force between the threads ensure a tight connection between the two connecting pipe bodies, effectively resisting internal fluid pressure and external forces such as tension and pressure. This prevents the connection from easily loosening, ensuring the stability of large pipeline systems during operation. When under stress, the threaded connection distributes the force evenly along the helix of the thread throughout the connection, preventing stress concentration at a single point or in a small area. This allows the connecting assembly to withstand greater external forces, reducing problems such as pipe rupture and loosening caused by stress concentration, and extending the service life of the pipeline system.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-4A large-scale bidirectional pipe connection assembly includes a first connecting pipe body 1. One side of the first connecting pipe body 1 has an annular sealing groove 2, and one end of the annular sealing groove 2 has an elastic sealing ring 3, which is positioned and connected to the first connecting pipe body 1. One side of the first connecting pipe body 1 has an external thread 11, which is welded to one end of the first connecting pipe body 1. The surface of the first connecting pipe body 1 has a second positioning flange 10, and the top of the second positioning flange 10 has a first clamp 5, which is fitted to the second positioning flange 10. One side of the clamp 5 is provided with a fastening threaded bolt 6, and the fastening threaded bolt 6 is threadedly connected to the first clamp 5. The bottom of the first clamp 5 is provided with a second clamp 9, and the second clamp 9 is threadedly connected to the first clamp 5 through the fastening threaded bolt 6. The inside of the second positioning flange 10 is provided with a positioning bolt 4. One side of the first connecting pipe body 1 is provided with a second connecting pipe body 7. The inner surface of the second connecting pipe body 7 is provided with an internal thread 13, and the internal thread 13 is processed by scanning and cutting. The surface of the second connecting pipe body 7 is provided with a first positioning flange 8, and one side of the second connecting pipe body 7 is provided with an annular boss 12.

[0027] An annular sealing groove 2 is provided on one side of the first connecting pipe body 1, and an elastic sealing ring 3 is provided at one end of the annular sealing groove 2. The design of the annular sealing groove 2 provides a precise installation position for the elastic sealing ring 3, enabling it to stably perform its sealing function. It realizes the elastic characteristics of the elastic sealing ring 3 itself, which can fit tightly against the inner wall of the pipe during pipe connection, filling any gaps and forming the first line of defense for sealing. Moreover, the cooperation between the annular sealing groove 2 and the elastic sealing ring 3 is equivalent to constructing a double sealing structure, which greatly enhances the sealing effect and effectively prevents the leakage of fluid media in the pipe. The elastic sealing ring 3 can automatically adjust the sealing state according to changes in the pressure inside the pipe and slight deformation of the pipe. A first clamp 5 is provided on the top of the second positioning flange 10, a fastening threaded bolt 6 is provided on one side of the first clamp 5, and a second clamp 9 is provided at the bottom of the first clamp 5. The combined structure of the first clamp 5 and the second clamp 9 tightens the pipe from two directions, which realizes that the pipe is firmly fixed on the positioning flange, effectively preventing the pipe from loosening or falling off during operation. Meanwhile, for large pipelines, due to their significant weight and potential for bearing substantial pressure and external forces, the clamp structure provides sufficient clamping force to ensure the stability of the pipeline connection. The installation of the threaded bolt 6 allows for adjustment of the clamp's tightness according to actual needs. During installation, workers can adjust the clamp's clamping force on the pipeline by tightening or loosening the threaded bolt to accommodate different pipeline materials. The first connecting pipe body 1 has an external thread 11 on one side, and the second connecting pipe body 7 has an internal thread 13 on its inner surface. This allows for initial positioning of the two pipes during installation, enabling the external thread 11 and internal thread 13 to engage in multiple turns. During tightening, the friction and interlocking force between the threads tightly bind the two connecting pipe bodies together, effectively resisting internal fluid pressure and external forces such as tension and pressure, ensuring the connection does not easily loosen and guaranteeing the stability of the large pipeline system during operation. When the threaded connection is under stress, the force is evenly distributed along the helical direction of the thread throughout the entire connection, avoiding stress concentration at a single point or in a small area. This allows the connection components to withstand greater external forces, reducing problems such as pipe rupture and loose connections caused by stress concentration, and extending the service life of the piping system. Specific Implementation Example 2:

[0029] Reference Figure 1-4 Pressure sensors are installed inside the first connecting pipe body 1 and the second connecting pipe body 7. These pressure sensors can detect changes in the pressure of the fluid inside the pipeline in real time and convert them into measurable signals such as electrical signals. Operators can check the pressure inside the pipeline at any time through connected monitoring equipment or systems, and promptly understand the operating status of the pipeline, providing real-time data support for the safe operation of the pipeline system.

[0030] In summary:

[0031] 1. An annular sealing groove 2 is provided on one side of the first connecting pipe body 1, and an elastic sealing ring 3 is provided at one end of the annular sealing groove 2. The design of the annular sealing groove 2 provides a precise installation position for the elastic sealing ring 3, enabling it to stably perform its sealing function. This realizes the elastic properties of the elastic sealing ring 3 itself, allowing it to fit tightly against the inner wall of the pipe during pipe connection, filling any gaps and forming the first line of defense for sealing. Moreover, the cooperation between the annular sealing groove 2 and the elastic sealing ring 3 is equivalent to constructing a double sealing structure, which greatly enhances the sealing effect and effectively prevents leakage of fluid media in the pipe. The elastic sealing ring 3 can automatically adjust the sealing state according to changes in the pressure inside the pipe and slight deformation of the pipe.

[0032] 2. A first clamp 5 is installed at the top of the second positioning flange 10, a fastening threaded bolt 6 is installed on one side of the first clamp 5, and a second clamp 9 is installed at the bottom of the first clamp 5. The combined structure of the first clamp 5 and the second clamp 9 clamps the pipeline from two directions, effectively fixing the pipeline tightly to the positioning flange and preventing the pipeline from loosening or falling off during operation. For large pipelines, which are heavy and may withstand significant pressure and external forces, this clamp structure provides sufficient clamping force to ensure the stability of the pipeline connection. The fastening threaded bolt 6 allows the clamp's tightness to be adjusted according to actual needs. During installation, workers can adjust the clamp's clamping force on the pipeline by tightening or loosening the threaded bolt to adapt to different pipeline materials.

[0033] 3. The first connecting pipe body 1 has an external thread 11 on one side, and the second connecting pipe body 7 has an internal thread 13 on its inner surface. This allows for initial positioning of the two pipes during installation, enabling the external thread 11 and internal thread 13 to engage in multiple turns. During tightening, the friction and engagement force between the threads tightly bind the two connecting pipe bodies together, effectively resisting internal fluid pressure and external forces such as tension and pressure. This ensures the connection will not easily loosen, guaranteeing the stability of the large pipeline system during operation. When under stress, the threaded connection distributes the force evenly along the helix of the thread throughout the connection, preventing stress concentration at a single point or in a small area. This allows the connecting assembly to withstand greater external forces, reducing problems such as pipe rupture and loosening caused by stress concentration, and extending the service life of the pipeline system.
