Description

Technical Field

[0001] This utility model belongs to the field of pipe fittings technology and relates to a spherical elbow. Background Technology

[0002] In the field of building water supply and drainage, water flow in pipes generates noise, especially when the water flows through a 90° bend in the pipe, where the direction of water flow suddenly changes from vertical to horizontal. The impact of the water flow on the pipe is greater, generating more noise and may even cause eddies and turbulence. Especially at night, the obvious noise generated by the fast-flowing water in the multi-channel bend hitting the inner wall of the pipe can seriously affect people's rest and the peace of home. In addition, the existing multi-channel bends are mainly T-shaped tees, which have the defect of uneven water flow distribution at the branch points. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a spherical elbow. The technical problem this invention aims to solve is the issue of uneven fluid distribution and significant noise generation at branch points in existing multi-channel elbows.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A spherical elbow includes a main body, characterized in that the main body has a plurality of branch pipes respectively communicating with the main body, the main body is spherical, and each branch pipe has a plurality of flow guiding protrusions on its inner wall, the flow guiding protrusions extending spirally from the water inlet end to the water outlet end of the branch pipe, and the inner wall of the branch pipe has noise reduction holes opened along the length direction of the branch pipe, the noise reduction holes being multiple and spaced apart along the circumference of the branch pipe.

[0006] The main body of this spherical elbow is spherical. On one hand, the symmetrical structure of the sphere ensures that the flow path from the center point to the inlet of any branch pipe on the main body is geometrically equal in length, thus solving the problem of uneven fluid distribution at branch points in existing multi-channel elbows. On the other hand, it slows down the fluid velocity as it passes through the main body. Furthermore, the inner walls of the branch pipes have several guiding protrusions that act as flow dividers, significantly reducing turbulence, eddies, and pressure drop when the fluid changes direction or merges / diversifies, thus helping to minimize destructive forces. The turbulence and potential cavitation phenomena also help the fluid to be distributed more evenly to each branch pipe, thereby dispersing the impact force of the fluid, reducing vibration and noise, and reducing the wear of the fluid on the pipe wall, extending the service life of this spherical elbow. Furthermore, the pipe wall of the branch pipe has multiple noise reduction holes opened along the length of the branch pipe. After the spherical elbow is connected to the pipe, an air gap can be formed in the noise reduction holes, thereby reducing the impact sound of the fluid by utilizing the principle of sound wave reflection, further reducing the generation of noise, and thus solving the problem of the large noise generated during the use of existing multi-channel elbows.

[0007] In the aforementioned spherical elbow, several of the flow-guiding protrusions are evenly distributed along the circumference of the branch pipe body. This improves the flow-guiding effect of the protrusions on the fluid, thereby better dispersing the impact force of the fluid and reducing vibration and noise.

[0008] In the aforementioned spherical elbow, the noise-reducing holes have an elliptical cross-section and are evenly distributed along the circumference of the branch pipe. This further reduces noise generation.

[0009] In the aforementioned spherical elbow, there is an even number of branch pipes, and the inlet ends of several branch pipes are arranged in pairs facing each other. This makes the structure of the spherical elbow more reasonable, allowing fluid impact force and gravity load to be transmitted evenly, avoiding local stress concentration, and extending the service life of the spherical elbow.

[0010] In the aforementioned spherical elbow, at least one branch pipe body is L-shaped and cylindrical, with several guide protrusions on the branch pipe body located on two straight pipe sections, while the remaining branch pipe bodies are straight and cylindrical. This allows the spherical elbow to connect better to the pipe material and also facilitates its processing and manufacturing.

[0011] In the aforementioned spherical elbow, the main pipe and several branch pipes are integrally formed, and the wall thickness of the main pipe and the branch pipes is the same. This gives the spherical elbow high strength and pressure-bearing capacity, avoids potential weak points caused by welds (especially in high-stress areas), has high overall strength, can withstand higher pressure, and reduces the risk of leakage at the connection between the main pipe and the branch pipes.

[0012] Compared with existing technologies, the advantages of this spherical elbow are as follows: The main body of this spherical elbow is spherical. On the one hand, the symmetrical structure of the sphere ensures that the flow path of the fluid from the center point to the inlet of any branch pipe on the main body is geometrically equal, thus solving the problem of uneven fluid distribution at the branches in existing multi-channel elbows. On the other hand, the fluid velocity slows down when passing through the main body. In addition, the inner walls of the branch pipes have several guiding protrusions, which can guide the fluid flow and significantly reduce turbulence, eddies, and pressure drop when the fluid changes direction or merges / diversifies. This design helps reduce destructive turbulence and potential cavitation, and also facilitates more even distribution of fluid to each branch pipe, thereby dispersing the impact force of the fluid, reducing vibration and noise. It also reduces fluid wear on the branch pipe wall, extending the service life of the spherical elbow. Furthermore, the branch pipe wall has multiple noise reduction holes along its length. After the spherical elbow is connected to the pipe, an air gap is formed in the noise reduction holes, which reduces fluid impact noise by utilizing the principle of sound wave reflection, further reducing noise generation and thus solving the problem of excessive noise generated during the use of existing multi-channel elbows.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] A type of spherical elbow, see reference Figure 1 and Figure 2 The system includes a main body 1, which has several branch pipes 2 that are respectively connected to the main body 1. The main body 1 is spherical. Each branch pipe 2 has several flow guiding protrusions 2a on its inner wall. The flow guiding protrusions 2a extend spirally from the water inlet end to the water outlet end of the branch pipe 2. The inner wall of the branch pipe 2 has noise reduction holes 2b opened along the length direction of the branch pipe 2. There are multiple noise reduction holes 2b, which are spaced apart along the circumference of the branch pipe 2.

[0018] In this embodiment, it is preferred that a plurality of the flow guiding protrusions 2a are evenly distributed along the circumference of the branch pipe body 2; it is preferred that the cross-section of the noise reduction hole 2b is elliptical and the noise reduction hole 2b is evenly distributed along the circumference of the branch pipe body 2; it is preferred that there is an even number of branch pipe bodies 2, and the water inlet ends of the plurality of branch pipe bodies 2 are arranged opposite each other in pairs; it is preferred that the main pipe body 1 and the plurality of branch pipe bodies 2 are integrally formed, and the pipe wall thickness of the main pipe body 1 and the branch pipe body 2 is the same.

[0019] Reference Figure 1 and Figure 2 Furthermore, at least one of the branch pipe bodies 2 is L-shaped cylindrical, and several flow guiding protrusions 2a on the branch pipe body 2 are respectively located on two straight pipe sections, while the remaining branch pipe bodies 2 are straight cylindrical.

[0020] The main body 1 of this spherical elbow is spherical. On one hand, the symmetrical structure of the sphere ensures that the flow path from the center point to the inlet of any branch pipe 2 on the wall of the main body 1 is geometrically equal in length, thus solving the problem of uneven fluid distribution at branch points in existing multi-channel elbows. On the other hand, it slows down the flow velocity as the fluid passes through the main body 1. Furthermore, the inner walls of the branch pipes 2 each have several guiding protrusions 2a, which act as diversion and guidance points for the fluid, significantly reducing turbulence, eddies, and pressure drop when the fluid changes direction or merges / diversifies, thus helping to reduce destructive forces. The turbulence and potential cavitation phenomena also help the fluid to be distributed more evenly to each branch pipe body 2, thereby dispersing the impact force of the fluid, reducing vibration and noise, and reducing the wear of the fluid on the pipe wall of the branch pipe body 2, extending the service life of this spherical elbow. Furthermore, the pipe wall of the branch pipe body 2 has multiple noise reduction holes 2b opened along the length direction of the branch pipe body 2. After the spherical elbow is connected to the pipe, an air gap can be formed in the noise reduction holes 2b, thereby reducing the impact sound of the fluid by utilizing the principle of sound wave reflection, further reducing the generation of noise, and thus solving the problem of the large noise generated during use of existing multi-channel elbows.
