Description

Technical Field

[0001] This utility model relates to the field of plastic tee pipe technology, specifically a tee pipe with an external reinforcement structure. Background Technology

[0002] A plastic tee is a pipe fitting with three interfaces, which can be either one inlet and two outlets or two inlets and one outlet. It is used to connect three pipes of the same or different diameters and is widely used in liquid and gas transportation systems in construction, industry, agriculture and other fields.

[0003] Plastic tee pipes can be connected in several ways, including adhesive bonding, heat fusion bonding, threaded bonding, and snap-fit ​​bonding. Adhesive bonding is suitable for connecting PVC and other plastic pipes; heat fusion bonding is suitable for systems requiring high-strength connections with thermoplastic pipes such as PE and PP; threaded bonding is suitable for piping systems that require frequent disassembly or maintenance; and snap-fit ​​bonding is suitable for connecting semi-rigid flexible hoses and is commonly used in scenarios requiring quick installation and disassembly.

[0004] In many adhesive-bonded and thermoplastic-fused plastic tee fittings, the connected pipes are integral structures. Compared to the connected pipes, the contact area or size between the existing tee fitting and the pipe connection is very small. Within the entire piping system, due to factors such as vibration, internal pressure, external forces, and thermal expansion and contraction, the connection area is very small, resulting in high local stress and severely testing the connection strength. Due to market demand, and to improve the connection structure strength of the tee fitting and enhance the reliability of the piping system, a tee fitting with an external reinforcement structure has been designed and proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tee pipe with an external reinforcement structure to improve the connection structure strength of the tee pipe.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A tee pipe with an external reinforcement structure includes an integral main pipe and a branch pipe. The main pipe and the branch pipe are provided with insertion grooves near their ends. The flow channels inside the main pipe and the branch pipe are connected to the insertion grooves.

[0008] Both the main pipe and the branch pipe have threaded grooves on their outer walls. Both the main pipe and the branch pipe are threadedly connected to a reinforcing sleeve through the threaded grooves. The end of the reinforcing sleeve has a through groove at the position corresponding to the insertion groove, and the outer wall of the reinforcing sleeve has a hexagonal protrusion.

[0009] The connection between the main pipe and the branch pipe is provided with a thickened layer located between three reinforcing sleeves.

[0010] Preferably, the diameter of the insertion slot is larger than the diameter of the flow channel.

[0011] Preferably, the inner wall of the insertion slot is provided with annular sealing grooves at equal intervals along the axial direction.

[0012] Preferably, the diameters of the through groove and the insertion groove are equal.

[0013] Preferably, the inner wall of the through groove is provided with anti-slip protrusions at equal intervals along the axial direction.

[0014] Preferably, the anti-slip protrusion has a triangular cross-section, and the side of the anti-slip protrusion closest to the flow channel and the side away from the flow channel are respectively a vertical surface and an inclined surface.

[0015] Preferably, the hexagonal protrusion is disposed on the outer wall of the end of the reinforcing sleeve opposite to the flow channel.

[0016] Preferably, the thickened layer is an integral structure with the main pipe and the branch pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides insertion grooves within the main and branch pipes, allowing for the insertion of corresponding pipes via adhesive bonding or heat fusion, thereby increasing the overlap between them. A reinforcing sleeve is then fitted onto the connected pipes, and by screwing the reinforcing sleeve along the threaded groove on the main or branch pipe, the overlap is further increased. The reinforcing sleeve can also be further reinforced with the main and branch pipes, as well as the connected pipes, through adhesive bonding or heat fusion. Simultaneously, the connection between the main and branch pipes is strengthened with a thickened layer. By reinforcing the outside of the tee pipe, the structural strength of the tee pipe itself and its connection with the corresponding pipes is increased, thus improving the reliability of the road system.

[0026] 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.

[0027] like Figure 1-6 As shown, this utility model provides a technical solution: a tee pipe with an external reinforcement structure, including a main pipe 1 and a branch pipe 2 with an integral structure. A thickened layer 9 is provided on the outside of the connection between the main pipe 1 and the branch pipe 2, located between three reinforcing sleeves 6. The thickened layer 9 is an integral structure with the main pipe 1 and the branch pipe 2, increasing the connection strength between the main pipe 1 and the branch pipe 2.

[0028] Both the main pipe 1 and the branch pipe 2 are provided with insertion grooves 3 near their ends. The flow channels 4 inside the main pipe 1 and the branch pipe 2 are connected to the insertion grooves 3. The diameter of the insertion grooves 3 is larger than the diameter of the flow channels 4, and is used to insert the connected pipes. The inner wall of the insertion grooves 3 is provided with annular sealing grooves 10 at equal intervals along the axial direction. Multiple annular sealing grooves 10 form a gradient seal to prevent fluid leakage from directly penetrating out.

[0029] Both the main pipe 1 and the branch pipe 2 have threaded grooves 5 on their outer walls. Both the main pipe 1 and the branch pipe 2 are threadedly connected to the reinforcing sleeve 6 through the threaded grooves 5. The outer wall of the reinforcing sleeve 6 is provided with a hexagonal protrusion 8. The hexagonal protrusion 8 is located on the outer wall of the reinforcing sleeve 6 at the end opposite to the flow channel 4, which makes it easy to turn with a wrench.

[0030] The end of the reinforcing sleeve 6 is provided with a through groove 7 at the position corresponding to the insertion groove 3. The diameter of the through groove 7 is equal to that of the insertion groove 3, ensuring that the reinforcing sleeve 6 can be smoothly fitted onto the connected pipe. Anti-slip protrusions 11 are provided equidistantly along the axial direction on the inner wall of the through groove 7. The cross-section of the anti-slip protrusions 11 is triangular, and the side of the anti-slip protrusions 11 near the flow channel 4 and the side away from the flow channel 4 are vertical and inclined respectively, which are used to prevent the connection from falling off.

[0031] Working principle:

[0032] Remove the reinforcing sleeve 6 from the main pipe 1 and branch pipe 2, and put it on the pipe to be connected. Apply glue or heat fusion to the end surface of the pipe and insert it into the spigot groove 3 to complete the initial connection with the main pipe 1 and branch pipe 2. The reinforcing sleeve 6 is connected to the main pipe 1 or branch pipe 2 through the threaded groove 5, so as to extend the length of the pipe to the connected pipe based on the main pipe 1 and branch pipe 2. The reinforcing sleeve 6 can also be reinforced by applying glue or heat fusion to the main pipe 1, branch pipe 2 and connected pipe, which improves the structural strength of the connection between the tee pipe and the connected pipe. At the same time, a thickened layer 9 is set at the connection between the main pipe 1 and branch pipe 2 to increase its own structural strength and improve the reliability of the pipeline system.
