Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing and flow guiding technology, specifically to an end cap pipeline structure. Background Technology

[0002] Pipe end caps are devices used to seal pipe ends in a piping system. They are usually fixed by welding to provide a permanent seal. As a key end sealing and flow guiding component in a piping system, end caps are of great significance.

[0003] Existing end caps are mostly made of aluminum. Although aluminum end caps have certain strength and corrosion resistance, their high density makes them heavy, especially during batch installation of pipeline systems or high-altitude operations. This increases the difficulty of transportation and the intensity of manual handling, and may even require the use of hoisting equipment, significantly increasing construction costs. Furthermore, the flow guiding and sealing functions of aluminum end caps still require separate design: additional aluminum flow guiding pipes need to be welded and rubber seals need to be assembled. This not only makes the structure complex, but also causes problems such as easy corrosion at the weld joints and high precision requirements for the assembly of seals. Therefore, an end cap pipeline structure is proposed. Utility Model Content

[0016] 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.

[0017] Please see Figures 1-4 This utility model discloses an end cap pipeline structure, including a container inner wall 1, and a flow guiding structure is provided at the top of the container inner wall 1; The inner wall of container inner wall 1 is provided with a sealing structure.

[0018] Specifically, the inner wall 1 of the container is made of PA6GF35 engineering plastic, which provides the mounting base for the flow guiding structure and sealing structure, and also serves as a channel for temporary storage or transmission of fluid.

[0019] In this embodiment, the flow guiding structure includes a container outer wall 2 disposed at the top of the container inner wall 1, a plastic clip 3 fixedly connected to the top of the container outer wall 2, and a plurality of threaded connectors 12 fixedly connected to one side of the outer wall of the plastic clip 3.

[0020] Specifically, a plastic clip 3 is integrally formed and fixed at the top of the outer wall 2 of the container. The plastic clip 3 is made of thickened plastic material and serves as the installation carrier for the flow channel and sealing structure. Multiple threaded connectors 12 are evenly fixed on one side of the outer wall of the plastic clip 3 to ensure that the plastic clip 3 and the outer wall 2 of the container are connected more firmly.

[0021] In this embodiment, the inner walls of multiple threaded connectors 12 are connected to bushings 6, and the inner walls of the bushings 6 are all fixedly connected to the outer wall 2 of the container by connecting bolts.

[0022] Specifically, a bushing 6 is connected to the inner wall of the threaded connector 12 to ensure that the plastic clip 3 is firmly connected to the outer wall 2 of the container and to prevent loosening under fluid pressure.

[0023] In this embodiment, the flow guiding structure also includes an internal flow guiding channel 11 opened at the top of the plastic card block 3. An internal flow guiding pipe 7 is fixedly connected to the bottom end of the internal flow guiding channel 11, and a plastic top cover 4 is welded to the top end of the internal flow guiding channel 11. The internal flow guiding pipe 7 is located inside the inner wall 1 of the container.

[0024] Specifically, the top of the plastic card block 3 has an internal flow channel 11, which is a straight cylindrical design. The bottom of the internal flow channel 11 is integrally formed and fixed with an internal flow pipe 7. The internal flow pipe 7 extends into the inner wall 1 of the container and is coaxially arranged with the inner wall 1 of the container to ensure that the fluid can be stably transmitted. The top of the internal flow channel 11 is welded with a plastic top cover 4, which is used to conduct the fluid medium into the flow port 9.

[0025] In this embodiment, a drainage port 10 is fixedly connected to one side of the outer wall of the plastic card block 3, and a guide port 9 is opened on the inner wall of the drainage port 10. The guide port 9 is connected to the internal guide channel 11.

[0026] Specifically, a flow port 10 is integrally formed and fixed on one side of the outer wall of the plastic card block 3. The flow port 10 is used to realize the branch transmission of fluid. A guide port 9 is opened on the inner wall of the flow port 10. The guide port 9 is connected to the internal guide channel 11 to ensure that the branch fluid can be drawn out.

[0027] In this embodiment, the sealing structure includes an internal dam 8 fixed to the bottom of the plastic block 3, and the internal dam 8 surrounds the internal guide pipe 7.

[0028] Specifically, the internal cofferdam 8 is an annular protruding structure, integrally formed with the plastic clip 3, and surrounds the internal guide pipe 7. When the end cap is connected to the pipeline, the internal cofferdam 8 is inserted into the inside of the pipeline interface, forming the first sealing barrier to prevent fluid from leaking from the gap between the end cap and the pipeline.

[0029] In this embodiment, a sealing ring 5 is embedded at the bottom edge of the plastic card block 3. One end of the sealing ring 5 surrounds the outer wall of the inner cofferdam 8, and the other end of the sealing ring 5 surrounds the bottom outer wall of the guide port 9.

[0030] Specifically, a sealing ring 5 is embedded at the bottom edge of the plastic block 3. The sealing ring 5 is made of rubber and has good elasticity and corrosion resistance. One end of the sealing ring 5 is wrapped around the outer wall of the inner cofferdam 8, and the other end is wrapped around the bottom outer wall of the guide port 9, forming a second sealing barrier. Through the compression deformation when the bolts are tightened, the tiny gap between the plastic block 3 and the pipeline interface is filled, achieving double sealing protection.

[0031] The working principle and usage process of this utility model are as follows: During use, the internal cofferdam 8 of the end cap pipeline structure is aligned with and inserted into the inner wall 1 of the container. Through the threaded connection seat 12 on the outer wall of the plastic clip 3, the connecting bolt is passed through the bushing 6 and screwed into the preset screw hole on the outer wall 2 of the container. As the bolt is tightened, the plastic clip 3 gradually approaches the outer wall 2 of the container. The sealing ring 5 is compressed and undergoes elastic deformation, filling the gap between the parts and forming a seal. When the fluid enters the end cap from the container, it first flows along the hole on one side of the inner wall 1 of the container, enters the plastic top cap 4 through the hole, and then enters the internal guide channel 11 of the plastic clip 3. The fluid enters the outlet 10 through the guide port 9 from the internal guide channel 11, and then is transported to the target position through the branch pipeline connected to the outlet 10. Finally, it flows out from the internal guide pipe 7. During the fluid transmission process, the internal cofferdam 8 prevents the fluid from seeping into the gap between the end cap and the pipeline, forming the first layer of protection. The sealing ring 5 is compressed and deformed to fit tightly against the mating surface, further preventing fluid leakage. The double sealing structure ensures no leakage.
