Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a high-pressure tee pipe. Background Technology

[0002] Piping systems are an essential and indispensable part of daily life, serving purposes such as water supply, sewage disposal, waste disposal, and transportation. Existing pipe fittings such as elbows, tees, and sleeves generally have uniform wall thickness. However, most tee fittings on the market are designed with significantly thicker walls than pipes or elbows / sleeves of the same specifications and pressure rating. While this solves the problem of tees being weak and prone to breakage in piping systems and improves the pressure-bearing capacity of the fittings, it also significantly increases the weight and cost of the products.

[0003] For example, Chinese Patent Publication No. CN105042244A, published on November 11, 2025, entitled "Three-way Pipe," includes a horizontal pipe and a vertical pipe. The vertical pipe is vertically connected to the middle of the horizontal pipe, and the vertical pipe and the horizontal pipe are connected. A reinforcing rib is provided on each side of the vertical pipe between it and the horizontal pipe. The horizontal pipe, the vertical pipe, and the reinforcing rib are an integral structure.

[0004] The drawback of existing patents is that while existing tee fittings address the issue of weak and easily broken tees in piping systems by increasing the overall wall thickness, this significantly increases the weight and cost of the tee fittings. Utility Model Content

[0005] The purpose of this invention is to improve the problem that increasing the overall wall thickness of existing tee fittings to strengthen weak and easily broken parts of the tee fittings results in a significant increase in the weight and cost of the tee fittings. The invention provides a high-pressure tee fitting that can strengthen the tee fittings without significantly increasing their weight and cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-pressure-bearing tee pipe includes a main pipe and a branch pipe disposed on the side wall of the main pipe. The junction of the outer walls of the main pipe and the branch pipe has a rounded corner structure. A reinforcing block is provided on the belly of the tee pipe at the apex of the tee shoulder, and reinforcing ribs are provided on both sides of the reinforcing block at the junction of the outer walls of the main pipe and the branch pipe. This high-pressure-bearing tee pipe improves the connection strength at the junction of the main pipe and the branch pipe by providing a rounded corner structure at the junction of the outer walls of the main pipe and the branch pipe. While the rounded corner structure increases the overall strength of the junction, the connection strength at the belly of the tee is not significantly strengthened, as there is a stress concentration point at the apex of the tee shoulder at the belly of the tee. Therefore, this solution provides a reinforcing block at the apex of the tee shoulder at the belly of the main pipe. This localized reinforcement helps to disperse stress concentration and significantly improves the pressure-bearing performance of the tee pipe junction. Reinforcing ribs are provided on both sides of the reinforcing block at the junction of the outer walls of the main pipe and the branch pipe, connecting the outer walls of the main pipe and the branch pipe, thereby strengthening the connection strength between the main pipe and the branch pipe. The rounded corner structure, reinforcing block, and reinforcing rib are simultaneously installed at the connection of the tee fitting to enhance the strength of the connection between the main pipe and the branch pipe, as well as the pressure resistance of the tee, significantly reducing the risk of breakage at the connection. Furthermore, the inclusion of the rounded corner structure, reinforcing block, and reinforcing rib does not significantly increase the weight or cost of the tee.

[0008] Preferably, the wall thickness of the branch pipe gradually increases towards the belly of the main tee on both sides, so that a saddle-shaped intersection line is formed at the junction of the outer walls of the main pipe and the branch pipe, and the outer wall of the branch pipe is flared with its opening facing the main pipe. The cross-section of the flared outer wall of the branch pipe gradually increases towards the belly of the main tee. With the inner diameter of the main pipe and the branch pipe remaining unchanged, the thickness at the junction of the main pipe and the branch pipe is increased, thereby locally increasing the connection strength at the junction of the main pipe and the branch pipe, without significantly increasing the weight and cost of the tee pipe.

[0009] Preferably, the thickened section of the branch pipe's outer wall is connected to the outer wall of the branch pipe via a beveled transition. This beveled transition connects the thickened section of the branch pipe's outer wall to the outer wall of the branch pipe, serving as a transition section to prevent stress concentration in this area caused by a sudden reduction in wall thickness.

[0010] Preferably, the junction of the inner walls of the main pipe and the branch pipe is designed with rounded corners. This prevents stress concentration at the junction. Normally, this area of ​​the tee is a sharp corner, where stress is concentrated, and if the tee expands, the sharp corner can easily tear.

[0011] Preferably, the inner wall of the main pipe is provided with a thickened section, the branch pipe is located at the thickened section of the main pipe, and the rounded corner structure at the junction of the inner walls of the main pipe and the branch pipe is located within the thickened section of the main pipe. By locally thickening a section of the main pipe where the branch pipe connects, the thickness of the main pipe and the connection strength at the junction of the main pipe and the branch pipe are locally increased, without significantly increasing the weight and cost of the tee pipe. Furthermore, the stepped surface formed between the thickened section and the inner wall of the main pipe can also be used for fitting insertion and positioning.

[0012] Preferably, the sidewalls at the junction of the main pipe and the branch pipe are thickened to form a thickened section, and the junction of the inner walls of the main pipe and the branch pipe within the thickened section is provided with a rounded corner structure. By locally thickening the junction of the main pipe and the branch pipe, the connection strength at the junction of the main pipe and the branch pipe is locally increased, without significantly increasing the weight and cost of the tee pipe.

[0013] Preferably, two reinforcing blocks are used, symmetrically arranged on both sides of the branch pipe along its central axis. This enhances the connection strength and pressure resistance at the junction of the main pipe and the branch pipe. The symmetrical arrangement of the two reinforcing blocks on both sides of the branch pipe along its central axis also ensures uniform stress distribution on both sides of the branch pipe connection tee.

[0014] Preferably, the two reinforcing ribs on the same side of the tee section of the main pipe are symmetrically arranged on both sides of the corresponding reinforcing block to ensure uniform stress on both sides of the reinforcing block.

[0015] Preferably, the reinforcing rib extends along the central axis of the branch pipe.

[0016] Preferably, the central axis of the branch pipe intersects with and is perpendicular to the central axis of the main pipe.

[0017] Therefore, this utility model has the following beneficial effects: by setting a rounded corner structure at the junction of the outer walls of the main pipe and the branch pipe, the connection strength at the junction of the main pipe and the branch pipe is improved; a reinforcing block is provided at the apex of the shoulder of the tee on the belly of the main pipe, and the local reinforcement helps to disperse the concentration of stress, which greatly improves the pressure bearing performance at the junction of the tee fittings; reinforcing ribs are provided on both sides of the reinforcing block at the junction of the outer walls of the main pipe and the branch pipe, and the reinforcing ribs connect the outer walls of the main pipe and the branch pipe, thereby strengthening the connection strength of the main pipe and the branch pipe; the strength of the junction of the main pipe and the branch pipe and the pressure bearing capacity of the tee are enhanced, the risk of breakage at the junction of the main pipe and the branch pipe is greatly reduced, and the weight and cost of the tee pipe are not significantly increased.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 The high-pressure tee pipe shown includes a main pipe 1 and a branch pipe 2 disposed on the side wall of the main pipe 1. The outer wall of the main pipe 1 and the branch pipe 2 are connected with a rounded corner structure 5. A reinforcing block 3 is provided at the top of the shoulder of the tee on the belly of the main pipe 1. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer wall of the main pipe 1 and the branch pipe 2.

[0026] Piping systems are an essential and indispensable part of daily life, serving purposes such as water supply, sewage disposal, waste disposal, and transportation. Existing pipe fittings such as elbows, tees, and sleeves generally have uniform wall thickness. Most tee fittings on the market are designed with a significantly thicker wall than pipes or elbows / sleeves of the same specifications and pressure rating. While this solves the problem of tees being weak and prone to breakage in piping systems, it also significantly increases the weight and cost of the product. To address the issue of significantly increasing the weight and cost of tee fittings by increasing the overall wall thickness to reinforce weak and easily broken areas, a high-pressure-bearing tee pipe is proposed that can enhance the strength of tee fittings without significantly increasing their weight and cost.

[0027] In the above embodiment, a high-pressure tee pipe is provided with a rounded corner structure 5 at the junction of the outer walls of the main pipe 1 and the branch pipe 2, thereby improving the connection strength at the junction. While the rounded corner structure 5 increases the overall strength of the junction, the connection strength at the tee's belly is not significantly enhanced, as stress concentration points exist at the apex of the tee shoulder. Therefore, in this solution, a reinforcing block 3 is provided at the apex of the tee shoulder on the belly of the main pipe 1. This localized reinforcement helps to disperse stress concentration and significantly improves the pressure-bearing performance of the tee pipe joint. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer walls of the main pipe 1 and the branch pipe 2. The reinforcing ribs 4 connect the outer walls of the main pipe 1 and the branch pipe 2, thereby strengthening the connection strength between the main pipe 1 and the branch pipe 2. The rounded corner structure 5, reinforcing block 3, and reinforcing rib 4 are simultaneously installed at the connection of the tee fitting to enhance the strength of the connection between the main pipe 1 and the branch pipe 2 and the pressure resistance of the tee, significantly reducing the risk of breakage at the connection between the main pipe 1 and the branch pipe 2. Furthermore, the installation of the rounded corner structure 5, reinforcing block 3, and reinforcing rib 4 does not significantly increase the weight and cost of the tee.

[0028] In this technical solution, the transition area between the branch pipe and the main pipe in the longitudinal section of the tee formed by the main pipe and the branch pipe is called the shoulder of the tee, and the side part of the main pipe centerline of the tee facing the branch pipe opening is called the belly of the tee.

[0029] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 The high-pressure tee pipe shown includes a main pipe 1 and a branch pipe 2 disposed on the side wall of the main pipe 1. The outer wall of the main pipe 1 and the branch pipe 2 are connected with a rounded corner structure 5. A reinforcing block 3 is provided at the top of the shoulder of the tee on the belly of the main pipe 1. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer wall of the main pipe 1 and the branch pipe 2.

[0030] In this embodiment, the wall thickness of the branch pipe 2 gradually increases towards the belly of the tee of the main pipe 1 on both sides, so that a saddle-shaped intersection line is formed at the junction of the outer walls of the main pipe 1 and the branch pipe 2, and the outer wall of the branch pipe 2 is flared with its opening facing the main pipe 1. The cross-section of the flared outer wall of the branch pipe 2 gradually increases towards the belly of the tee of the main pipe 1. With the inner diameter of the main pipe 1 and the branch pipe 2 remaining unchanged, the thickness at the junction of the main pipe 1 and the branch pipe 2 is increased, thereby locally increasing the connection strength at the junction of the main pipe 1 and the branch pipe 2, without significantly increasing the weight and cost of the tee pipe.

[0031] Further optimization was made to the thickened section of the outer wall of branch pipe 2, such as... Figure 3 , Figure 4As shown, the thickened section of the outer wall of branch pipe 2 is connected to the outer wall of branch pipe 2 via a beveled transition. The beveled transition connection between the thickened section of the outer wall of branch pipe 2 and the outer wall of branch pipe 2 serves as a transition section to prevent stress concentration in this area caused by a sudden reduction in wall thickness.

[0032] Further optimization was made to the junction of the inner walls of main pipe 1 and branch pipe 2, such as... Figure 3 , Figure 4 As shown, the junction of the inner walls of the main pipe 1 and the branch pipe 2 is designed with a rounded corner structure 5. This prevents stress concentration at the junction of the inner walls of the main pipe 1 and the branch pipe 2. Originally, this part of the tee had a sharp corner structure, which caused stress concentration. If the tee expands, the sharp corner structure is prone to tearing.

[0033] The reinforcing block 3 is further optimized by using two reinforcing blocks 3, which are symmetrically arranged on both sides of the branch pipe 2 according to the central axis of the branch pipe 2. This ensures that the connection strength and pressure-bearing capacity of the main pipe 1 and the branch pipe 2 are enhanced. The two reinforcing blocks 3 are also symmetrically arranged on both sides of the branch pipe 2 according to the central axis of the branch pipe 2 to ensure that the stress on both sides of the tee connecting the branch pipe 2 is uniform.

[0034] The reinforcing block 3 is further optimized by symmetrically placing two reinforcing ribs 4 on the sides of the tee on the same side of the main pipe 1. This ensures uniform stress on both sides of the reinforcing block 3.

[0035] The reinforcing rib 4 is further optimized, and the reinforcing rib 4 extends along the central axis of the branch pipe 2.

[0036] The main pipe 1 and branch pipe 2 are further optimized, with the central axis of branch pipe 2 intersecting and perpendicular to the central axis of main pipe 1.

[0037] The above embodiment improves the connection strength of the connection between the main pipe 1 and the branch pipe 2 by providing a rounded corner structure 5 at the junction of the outer walls of the main pipe 1 and the branch pipe 2. A reinforcing block 3 is provided at the apex of the shoulder of the tee on the belly of the main pipe 1. The local reinforcement helps to disperse the concentration of stress and greatly improves the pressure bearing performance of the tee pipe joint. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer walls of the main pipe 1 and the branch pipe 2. The reinforcing ribs 4 connect the outer walls of the main pipe 1 and the branch pipe 2 to strengthen the connection strength between the main pipe 1 and the branch pipe 2. This enhances the strength of the junction of the main pipe 1 and the branch pipe 2 and the pressure bearing capacity of the tee pipe, greatly reduces the risk of breakage at the junction of the main pipe 1 and the branch pipe 2, and does not significantly increase the weight and cost of the tee pipe.

[0038] Example 3, as Figure 1 , Figure 2 , Figure 3 , Figure 4The high-pressure tee pipe shown includes a main pipe 1 and a branch pipe 2 disposed on the side wall of the main pipe 1. The outer wall of the main pipe 1 and the branch pipe 2 are connected with a rounded corner structure 5. A reinforcing block 3 is provided at the top of the shoulder of the tee on the belly of the main pipe 1. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer wall of the main pipe 1 and the branch pipe 2.

[0039] In this embodiment, the junction of the inner walls of the main pipe 1 and the branch pipe 2 is provided with a rounded corner structure 5. This prevents stress concentration at the junction of the inner walls of the main pipe 1 and the branch pipe 2. Originally, this part of the tee had a sharp corner structure, which caused stress concentration. If the tee expands, the sharp corner structure is prone to tearing. The inner wall of the main pipe 1 is provided with a thickened section 6, and the branch pipe 2 is located at the thickened section 6 of the main pipe 1. The rounded corner structure 5 at the junction of the inner walls of the main pipe 1 and the branch pipe 2 is located within the thickened section 6 of the main pipe 1. By locally thickening the section of the main pipe 1 that connects to the branch pipe 2, the thickness of the main pipe 1 is locally increased, and the connection strength at the junction of the main pipe 1 and the branch pipe 2 is locally increased, without significantly increasing the weight and cost of the tee pipe. At the same time, the stepped surface formed between the thickened section 6 and the inner wall of the main pipe 1 can also be used for fitting insertion and positioning.

[0040] The branch pipe 2 is further optimized. The wall thickness on both sides of the branch pipe 2 near the belly of the tee of the main pipe 1 gradually increases towards the belly of the tee of the main pipe 1, so that a saddle-shaped intersection line is formed at the junction of the outer walls of the main pipe 1 and the branch pipe 2, and the outer wall of the branch pipe 2 is flared with its opening facing the main pipe 1. The cross-section of the flared outer wall of the branch pipe 2 gradually increases towards the belly of the tee of the main pipe 1. While keeping the inner diameter of the main pipe 1 and the branch pipe 2 unchanged, the thickness at the junction of the main pipe 1 and the branch pipe 2 is increased, thereby locally increasing the connection strength at the junction of the main pipe 1 and the branch pipe 2, without significantly increasing the weight and cost of the tee pipe.

[0041] The thickened section of the outer wall of branch pipe 2 is further optimized, and the thickened section of the outer wall of branch pipe 2 is connected to the outer wall of branch pipe 2 by a bevel transition. The bevel transition connection between the thickened section of the outer wall of branch pipe 2 and the outer wall of branch pipe 2 serves as a transition section to prevent stress concentration in this area caused by a sudden reduction in wall thickness.

[0042] The reinforcing block 3 is further optimized by using two reinforcing blocks 3, which are symmetrically arranged on both sides of the branch pipe 2 according to the central axis of the branch pipe 2. This ensures that the connection strength and pressure-bearing capacity of the main pipe 1 and the branch pipe 2 are enhanced. The two reinforcing blocks 3 are also symmetrically arranged on both sides of the branch pipe 2 according to the central axis of the branch pipe 2 to ensure that the stress on both sides of the tee connecting the branch pipe 2 is uniform.

[0043] The reinforcing block 3 is further optimized by symmetrically placing two reinforcing ribs 4 on the sides of the tee on the same side of the main pipe 1. This ensures uniform stress on both sides of the reinforcing block 3.

[0044] The reinforcing rib 4 is further optimized, and the reinforcing rib 4 extends along the central axis of the branch pipe 2.

[0045] The main pipe 1 and branch pipe 2 are further optimized, with the central axis of branch pipe 2 intersecting and perpendicular to the central axis of main pipe 1.

[0046] The above embodiment improves the connection strength of the connection between the main pipe 1 and the branch pipe 2 by providing a rounded corner structure 5 at the junction of the outer walls of the main pipe 1 and the branch pipe 2. A reinforcing block 3 is provided at the apex of the shoulder of the tee on the belly of the main pipe 1. The local reinforcement helps to disperse the concentration of stress and greatly improves the pressure bearing performance of the tee pipe joint. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer walls of the main pipe 1 and the branch pipe 2. The reinforcing ribs 4 connect the outer walls of the main pipe 1 and the branch pipe 2 to strengthen the connection strength between the main pipe 1 and the branch pipe 2. This enhances the strength of the junction of the main pipe 1 and the branch pipe 2 and the pressure bearing capacity of the tee pipe, greatly reduces the risk of breakage at the junction of the main pipe 1 and the branch pipe 2, and does not significantly increase the weight and cost of the tee pipe.

[0047] Example 4, as Figure 1 , Figure 2 , Figure 3 , Figure 4 The high-pressure tee pipe shown includes a main pipe 1 and a branch pipe 2 disposed on the side wall of the main pipe 1. The outer wall of the main pipe 1 and the branch pipe 2 are connected with a rounded corner structure 5. A reinforcing block 3 is provided at the top of the shoulder of the tee on the belly of the main pipe 1. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer wall of the main pipe 1 and the branch pipe 2.

[0048] In this embodiment, the junction of the inner walls of the main pipe 1 and the branch pipe 2 is provided with a rounded corner structure 5. This prevents stress concentration at the junction of the inner walls of the main pipe 1 and the branch pipe 2. Originally, this part of the tee had a sharp corner structure, which caused stress concentration. If the tee expands, the sharp corner structure is prone to tearing. The side wall of the junction of the main pipe 1 and the branch pipe 2 is thickened to form a thickened part 7, and the junction of the inner walls of the main pipe 1 and the branch pipe 2 within the thickened part 7 is provided with a rounded corner structure 5. By locally thickening the junction of the main pipe 1 and the branch pipe 2, the connection strength of the junction of the main pipe 1 and the branch pipe 2 is locally increased without significantly increasing the weight and cost of the tee pipe.

[0049] The branch pipe 2 is further optimized. The wall thickness on both sides of the branch pipe 2 near the belly of the tee of the main pipe 1 gradually increases towards the belly of the tee of the main pipe 1, so that a saddle-shaped intersection line is formed at the junction of the outer walls of the main pipe 1 and the branch pipe 2, and the outer wall of the branch pipe 2 is flared with its opening facing the main pipe 1. The cross-section of the flared outer wall of the branch pipe 2 gradually increases towards the belly of the tee of the main pipe 1. While keeping the inner diameter of the main pipe 1 and the branch pipe 2 unchanged, the thickness at the junction of the main pipe 1 and the branch pipe 2 is increased, thereby locally increasing the connection strength at the junction of the main pipe 1 and the branch pipe 2, without significantly increasing the weight and cost of the tee pipe.

[0050] The thickened section of the outer wall of branch pipe 2 is further optimized, and the thickened section of the outer wall of branch pipe 2 is connected to the outer wall of branch pipe 2 by a bevel transition. The bevel transition connection between the thickened section of the outer wall of branch pipe 2 and the outer wall of branch pipe 2 serves as a transition section to prevent stress concentration in this area caused by a sudden reduction in wall thickness.

[0051] The reinforcing block 3 is further optimized by using two reinforcing blocks 3, which are symmetrically arranged on both sides of the branch pipe 2 according to the central axis of the branch pipe 2. This ensures that the connection strength and pressure-bearing capacity of the main pipe 1 and the branch pipe 2 are enhanced. The two reinforcing blocks 3 are also symmetrically arranged on both sides of the branch pipe 2 according to the central axis of the branch pipe 2 to ensure that the stress on both sides of the tee connecting the branch pipe 2 is uniform.

[0052] The reinforcing block 3 is further optimized by symmetrically placing two reinforcing ribs 4 on the sides of the tee on the same side of the main pipe 1. This ensures uniform stress on both sides of the reinforcing block 3.

[0053] The reinforcing rib 4 is further optimized, and the reinforcing rib 4 extends along the central axis of the branch pipe 2.

[0054] The main pipe 1 and branch pipe 2 are further optimized, with the central axis of branch pipe 2 intersecting and perpendicular to the central axis of main pipe 1.

[0055] The above embodiment improves the connection strength of the connection between the main pipe 1 and the branch pipe 2 by providing a rounded corner structure 5 at the junction of the outer walls of the main pipe 1 and the branch pipe 2. A reinforcing block 3 is provided at the apex of the shoulder of the tee on the belly of the main pipe 1. The local reinforcement helps to disperse the concentration of stress and greatly improves the pressure bearing performance of the tee pipe joint. Reinforcing ribs 4 are provided on both sides of the reinforcing block 3 at the junction of the outer walls of the main pipe 1 and the branch pipe 2. The reinforcing ribs 4 connect the outer walls of the main pipe 1 and the branch pipe 2 to strengthen the connection strength between the main pipe 1 and the branch pipe 2.
