Description

Technical Field

[0001] The utility model relates to a pipe connection structure, more specifically, it relates to a Y-type three-way pipe connection structure. Background Art

[0002] The application areas of plastic pipe fittings are becoming increasingly wider, and the types of materials transported are also increasing. In the past, pipelines were mainly used for water supply and drainage, and the materials passing through the pipelines were mainly liquid. Now pipelines may be used for animal husbandry, and the materials transported are semi-solid and semi-liquid feces; on some mountains, it also involves the transportation of sand and even small particles of stone, which greatly increases the requirements for the wear resistance of pipelines and the structural strength of pipe fittings; in some special application fields, the use environment conditions are harsh, forcing the wall thickness and material cost of the product to increase, so how to balance the cost and performance of the product requires key analysis and consideration, and tee products are the most prone to rupture of all categories.

[0003] For example: Chinese patent announcement number CN208778954U, announcement date April 23, 2019, the name of the utility model is a combined Y-type three-way pipe fitting, and the application discloses a three-way pipe connector structure, including a main pipe, two branch pipes, and a three-way connector. The three-way connector is Y-shaped, and the main pipe and the two branch pipes are respectively movably connected to the three-way connector. The two branch pipes are both arc-shaped pipes, and the two arc-shaped pipes are symmetrically arranged relative to the main pipe. The two branch pipes have the same diameter, the main pipe is close to the branch pipe at one end with a small diameter, and the end away from the branch pipe has a large diameter. This solution can be replaced according to the damaged part of the three-way pipe without replacing the entire pipe fitting, saving costs. However, in this solution, the middle part of the three-way pipe connector is the area with the largest deformation. The expansion here will cause the chamfer stress on the side wall of the three-way pipe to be unable to be released, making the entire connector easy to scrap. Utility Model Content

[0004] The utility model overcomes the problem that the three-way pipe connection structure is easy to expand and cause damage to the connection structure, and provides a Y-shaped three-way pipe connection structure. This solution improves the strength of the three-way pipe connection structure and prevents the three-way pipe connection piece from expanding and causing damage to the connection piece.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a Y-shaped three-way pipe connection structure, including two side pipe connectors and a main pipe connector, the two side pipe connectors and the main pipe connector being integrally formed to form an intersection area, and the intersection area being provided with a first reinforcing rib. In this solution, the two side pipe connectors and the main pipe connector can be connected to the pipe structure to form a Y-shaped three-way pipe structure; the intersection area of the three connectors is the area most likely to produce deformation, and is prone to expansion and causing rupture of the three-way pipe connection structure. By providing the first reinforcing rib in the intersection area, the deformation of the portion covered by the first reinforcing rib can be reduced, thereby reducing the stress within the three-way pipe connection structure, thereby preventing the three-way pipe connection structure from rupture and improving its service life.

[0006] Preferably, a first limiting step is provided at the intersection of the side pipe connector and a second limiting step is provided at the intersection of the side pipe connector and the main pipe connector. The side pipe connector and the main pipe connector are used for socket-and-socket pipe insertion. The side pipe connector and the main pipe connector are radially inwardly indented to form the first limiting step and the second limiting step, respectively. Both the first limiting step and the second limiting step are annular steps that primarily limit the depth of insertion into the pipe.

[0007] Preferably, pipes are inserted into the side pipe connector and the main pipe connector, and the heights of the first and second limiting steps are both the same as the pipe wall thickness. The inward indentation of the first and second limiting steps is consistent with the pipe wall thickness, so that the inner wall of the pipe system has no obvious depressions or steps, ensuring smoother water flow, especially when transporting liquid-solid mixtures or sand, gravel, and rocks, without causing blockage and affecting the smoothness of the passage.

[0008] Preferably, a rounded corner is provided between the two side pipe connectors. The tee connection structure is susceptible to expansion under pressure, and stress is most concentrated at the 90° angle (the angle between the two side pipe connectors). Designing a chamfered or rounded corner can locally increase the product thickness and eliminate some of the pressure stress.

[0009] Preferably, a cross-section structure is provided between the side pipe connector and the main pipe connector. The angle between the side pipe connector and the main pipe connector is large, creating a stress-free point for the pipe, resulting in excellent performance. The cross-section structure can be formed by cutting along a specific curve, thereby reducing the wall thickness of the product and reducing costs.

[0010] Preferably, a second reinforcing rib is provided on the exterior of the side and main pipe connectors. This rib, located on the exterior of the pipe bodies of the side and main pipe connectors, near the main body, is primarily used for inserting and inserting the pipe structure. This second reinforcing rib structure increases overall strength and prevents cracking at the interface between the side and main pipe connectors.

[0011] Preferably, the exterior of the side and main pipe connectors is provided with a tapered surface. The non-pressure-bearing wall thickness at the edges of the tee connection (the edges of the side and main pipe connectors) is cut to reduce the product's weight. This structural design ensures that the product meets performance requirements while reducing costs.

[0012] Preferably, the second reinforcing rib is annular, with a groove structure distributed annularly on its surface. The second reinforcing rib can improve the structural strength of the exterior of the side pipe connector and the main pipe connector. However, after the second reinforcing rib is added, localized stress may occur within it. The groove structure can eliminate the stress within the second reinforcing rib while still ensuring the structural strength of the side pipe connector and the main pipe connector.

[0013] Preferably, the trough structure includes a first trough body and a second trough body, wherein the trough width of the first trough body is greater than the trough width of the second trough body. The trough structure includes two trough bodies of different sizes, thereby minimizing the material consumption of the second reinforcing rib while ensuring structural strength, thereby achieving the purpose of reducing costs.

[0014] Preferably, the first troughs and the second troughs are spaced apart and alternately distributed. The first and second troughs are spaced apart, that is, the trough structure is not continuously distributed on the second reinforcing rib, which provides a guarantee for the reinforcing effect of the second reinforcing rib; at the same time, the first and second troughs are alternately distributed, so that the strength distribution and stress effect in the second reinforcing rib are uniform, and the appearance of the three-way pipe connection structure can also be improved.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) the first reinforcing rib is provided in the intersection area, which can reduce the deformation of the portion covered by the first reinforcing rib, thereby reducing the stress inside the three-way pipe connection structure, avoiding the rupture of the three-way pipe connection structure, and improving the service life; (2) the inner wall of the pipe parts after forming the system has no obvious depressions or steps, which can make the water flow more smooth, especially when transporting some liquid-solid mixtures or sand and gravel blocks, without getting stuck and affecting the smoothness of the passage; (3) the weight of the three-way pipe connection structure is reduced, the cost is reduced, and the pressure-bearing effect is better.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be further described below with reference to specific embodiments and in conjunction with the accompanying drawings.

[0024] Example 1: Figure 1 and Figure 2 The Y-shaped three-way pipe connection structure shown includes a main pipe connector 1 and two side pipe connectors 2. The main pipe connector 1 and the two side pipe connectors 2 form a Y-shaped structure, and the two side pipe connectors 2 form a 90° angle, so that the angle between the main pipe connector 1 and the two side pipe connectors 2 is 135°. The two side pipe connectors 2 and the main pipe connector 1 are integrally formed. The connection between the two side pipe connectors 2 and the main pipe connector 1 is an intersection area 3 of the three. The intersection area 3 is distributed on both the front and rear sides. First reinforcing ribs 4 are provided on the intersection area 3. Two first reinforcing ribs 4 are provided in each intersection area 3, and the two first reinforcing ribs 4 are distributed in parallel.

[0025] like Figure 3 and Figure 5 As shown, a first limiting step 5 is provided on the inner wall of the two side tube connectors 2. The first limiting step 5 protrudes from the inner wall of the side tube connector 2 and forms an annular structure. Since the two side tube connectors 2 intersect as a whole, the two first limiting steps 5 also intersect with each other and are also located at the angle between the two side tube connectors 2. Since the angle between the two side tube connectors 2 is 90°, the stress here is most concentrated, and the first limiting step 5 can not only limit the pipe 7 inserted into the inside of the side tube connector 2, but also increase the wall thickness at the angle between the two side tube connectors 2, thereby improving the pressure bearing capacity of the side tube connector 2.

[0026] like Figure 6As shown, the pipe 7 is inserted into the side pipe connector 2, and the end of the pipe 7 abuts the first limiting step 5. The wall thickness of the pipe 7 is consistent with the height of the protrusion of the first limiting step 5. As a result, the inner wall of the pipe 7 after forming a system has no obvious depressions or steps, which makes the water flow smoother, especially when transporting liquid-solid mixtures or gravel and stones, without getting stuck and affecting the smoothness of the passage. If the height of the first limiting step 5 is too high, when the object is transported from the side pipe connector 2 to the main pipe connector 1, the material will remain in the side pipe connector 2 and cannot be fully transported into the main pipe connector 1. If the height of the first limiting step 5 is too low, when the object is transported from the side pipe connector 2 to the main pipe connector 1, some of the material will remain in the cavity of the intersection 3 and cannot be effectively input into the main pipe connector 1. Similarly, when the object is transported in the opposite direction from the main pipe connector 1 to the side pipe connector 2, a similar situation will occur.

[0027] Inside the main pipe connector 1, there is also a second limiting step 6, which is also used to limit the depth of the pipe 7. The second limiting step 6 is a raised annular structure on the inner wall of the main pipe connector 1. The wall thickness of the pipe 7 inside the main pipe connector 1 matches the height of the raised second limiting step 6. As a result, the inner wall of the pipe 7 formed into a system has no obvious depressions or steps, ensuring smooth water flow, especially when transporting liquid-solid mixtures or gravel and rocks, without getting stuck and affecting the smoothness of the passage. The first limiting step 5 and the second limiting step 6 do not intersect.

[0028] like Figure 2 and Figure 3 As shown, a fillet 8 is provided outside the included angle of the two side tube connectors 2. Since the included angle between the two side tube connectors 2 is 90°, the stress is most concentrated here. After designing the chamfer or fillet, the product thickness can be partially increased and part of the pressure stress can be eliminated.

[0029] like Figure 2 and Figure 4 As shown, a section structure 9 is provided between the side pipe connector 2 and the main pipe connector 1. Since the included angle between the main pipe connector 1 and the two side pipe connectors 2 is 135°, the area between the side pipe connector 2 and the main pipe connector 1 is a stress non-concentration point of the pipe fitting, which provides excellent performance. The section structure 9 can be formed by cutting along a certain curve to reduce the wall thickness of the product and achieve the purpose of reducing costs.

[0030] Example 2: Figure 1 and Figure 2The Y-shaped three-way pipe connection structure shown includes a main pipe connector 1 and two side pipe connectors 2. The main pipe connector 1 and the two side pipe connectors 2 form a Y-shaped structure, and the two side pipe connectors 2 form a 90° angle, so that the angle between the main pipe connector 1 and the two side pipe connectors 2 is 135°. The two side pipe connectors 2 and the main pipe connector 1 are integrally formed. The connection between the two side pipe connectors 2 and the main pipe connector 1 is an intersection area 3 of the three. The intersection area 3 is distributed on both the front and rear sides. First reinforcing ribs 4 are provided on the intersection area 3. Two first reinforcing ribs 4 are provided in each intersection area 3, and the two first reinforcing ribs 4 are distributed in parallel.

[0031] like Figure 3 and Figure 5 As shown, a first limiting step 5 is provided on the inner wall of the two side tube connectors 2. The first limiting step 5 protrudes from the inner wall of the side tube connector 2 and forms an annular structure. Since the two side tube connectors 2 intersect as a whole, the two first limiting steps 5 also intersect with each other and are also located at the angle between the two side tube connectors 2. Since the angle between the two side tube connectors 2 is 90°, the stress here is most concentrated, and the first limiting step 5 can not only limit the pipe 7 inserted into the inside of the side tube connector 2, but also increase the wall thickness at the angle between the two side tube connectors 2, thereby improving the pressure bearing capacity of the side tube connector 2.

[0032] like Figure 6 As shown, the pipe 7 is inserted into the side pipe connector 2, and the end of the pipe 7 abuts the first limiting step 5. The wall thickness of the pipe 7 is consistent with the height of the protrusion of the first limiting step 5. As a result, the inner wall of the pipe 7 after forming a system has no obvious depressions or steps, which makes the water flow smoother, especially when transporting liquid-solid mixtures or gravel and stones, without getting stuck and affecting the smoothness of the passage. If the height of the first limiting step 5 is too high, when the object is transported from the side pipe connector 2 to the main pipe connector 1, the material will remain in the side pipe connector 2 and cannot be fully transported into the main pipe connector 1. If the height of the first limiting step 5 is too low, when the object is transported from the side pipe connector 2 to the main pipe connector 1, some of the material will remain in the cavity of the intersection 3 and cannot be effectively input into the main pipe connector 1. Similarly, when the object is transported in the opposite direction from the main pipe connector 1 to the side pipe connector 2, a similar situation will occur.

[0033] Inside the main pipe connector 1, there is also a second limiting step 6, which is also used to limit the depth of the pipe 7. The second limiting step 6 is a raised annular structure on the inner wall of the main pipe connector 1. The wall thickness of the pipe 7 inside the main pipe connector 1 matches the height of the raised second limiting step 6. As a result, the inner wall of the pipe 7 formed into a system has no obvious depressions or steps, ensuring smooth water flow, especially when transporting liquid-solid mixtures or gravel and rocks, without getting stuck and affecting the smoothness of the passage. The first limiting step 5 and the second limiting step 6 do not intersect.

[0034] like Figure 2 and Figure 3 As shown, a fillet 8 is provided outside the included angle of the two side tube connectors 2. Since the included angle between the two side tube connectors 2 is 90°, the stress is most concentrated here. After designing the chamfer or fillet, the product thickness can be partially increased and part of the pressure stress can be eliminated.

[0035] like Figure 2 and Figure 4 As shown, a section structure 9 is provided between the side pipe connector 2 and the main pipe connector 1. Since the included angle between the main pipe connector 1 and the two side pipe connectors 2 is 135°, the area between the side pipe connector 2 and the main pipe connector 1 is a stress non-concentration point of the pipe fitting, which provides excellent performance. The section structure 9 can be formed by cutting along a certain curve to reduce the wall thickness of the product and achieve the purpose of reducing costs.

[0036] like Figure 1 or Figure 2 or Figure 5 As shown, a tapered surface 11 is provided on the outside of the ports of the side pipe connector 2 and the main pipe connector 1. The non-pressure-bearing wall thickness at the edge of the three-way pipe connection structure (the edge of the side pipe connector 2 and the main pipe connector 1) is cut to form the tapered surface 11, so that the weight of the product is reduced. Through the above structural design, the performance of the product meets the requirements and the cost is lower.

[0037] Example 3: Figure 1 and Figure 2 The Y-shaped three-way pipe connection structure shown includes a main pipe connector 1 and two side pipe connectors 2. The main pipe connector 1 and the two side pipe connectors 2 form a Y-shaped structure, and the two side pipe connectors 2 form a 90° angle, so that the angle between the main pipe connector 1 and the two side pipe connectors 2 is 135°. The two side pipe connectors 2 and the main pipe connector 1 are integrally formed. The connection between the two side pipe connectors 2 and the main pipe connector 1 is an intersection area 3 of the three. The intersection area 3 is distributed on both the front and rear sides. First reinforcing ribs 4 are provided on the intersection area 3. Two first reinforcing ribs 4 are provided in each intersection area 3, and the two first reinforcing ribs 4 are distributed in parallel.

[0038] like Figure 3 and Figure 5 As shown, a first limiting step 5 is provided on the inner wall of the two side tube connectors 2. The first limiting step 5 protrudes from the inner wall of the side tube connector 2 and forms an annular structure. Since the two side tube connectors 2 intersect as a whole, the two first limiting steps 5 also intersect with each other and are also located at the angle between the two side tube connectors 2. Since the angle between the two side tube connectors 2 is 90°, the stress here is most concentrated, and the first limiting step 5 can not only limit the pipe 7 inserted into the inside of the side tube connector 2, but also increase the wall thickness at the angle between the two side tube connectors 2, thereby improving the pressure bearing capacity of the side tube connector 2.

[0039] like Figure 6 As shown, the pipe 7 is inserted into the side pipe connector 2, and the end of the pipe 7 abuts the first limiting step 5. The wall thickness of the pipe 7 is consistent with the height of the protrusion of the first limiting step 5. As a result, the inner wall of the pipe 7 after forming a system has no obvious depressions or steps, which makes the water flow smoother, especially when transporting liquid-solid mixtures or gravel and stones, without getting stuck and affecting the smoothness of the passage. If the height of the first limiting step 5 is too high, when the object is transported from the side pipe connector 2 to the main pipe connector 1, the material will remain in the side pipe connector 2 and cannot be fully transported into the main pipe connector 1. If the height of the first limiting step 5 is too low, when the object is transported from the side pipe connector 2 to the main pipe connector 1, some of the material will remain in the cavity of the intersection 3 and cannot be effectively input into the main pipe connector 1. Similarly, when the object is transported in the opposite direction from the main pipe connector 1 to the side pipe connector 2, a similar situation will occur.

[0040] Inside the main pipe connector 1, there is also a second limiting step 6, which is also used to limit the depth of the pipe 7. The second limiting step 6 is a raised annular structure on the inner wall of the main pipe connector 1. The wall thickness of the pipe 7 inside the main pipe connector 1 matches the height of the raised second limiting step 6. As a result, the inner wall of the pipe 7 formed into a system has no obvious depressions or steps, ensuring smooth water flow, especially when transporting liquid-solid mixtures or gravel and rocks, without getting stuck and affecting the smoothness of the passage. The first limiting step 5 and the second limiting step 6 do not intersect.

[0041] like Figure 2 and Figure 3 As shown, a fillet 8 is provided outside the included angle of the two side tube connectors 2. Since the included angle between the two side tube connectors 2 is 90°, the stress is most concentrated here. After designing the chamfer or fillet, the product thickness can be partially increased and part of the pressure stress can be eliminated.

[0042] like Figure 2 and Figure 4As shown, a section structure 9 is provided between the side pipe connector 2 and the main pipe connector 1. Since the included angle between the main pipe connector 1 and the two side pipe connectors 2 is 135°, the area between the side pipe connector 2 and the main pipe connector 1 is a stress non-concentration point of the pipe fitting, which provides excellent performance. The section structure 9 can be formed by cutting along a certain curve to reduce the wall thickness of the product and achieve the purpose of reducing costs.

[0043] like Figure 1 or Figure 2 or Figure 5 As shown, a tapered surface 11 is provided on the outside of the ports of the side pipe connector 2 and the main pipe connector 1. The non-pressure-bearing wall thickness at the edge of the three-way pipe connection structure (the edge of the side pipe connector 2 and the main pipe connector 1) is cut to form the tapered surface 11, so that the weight of the product is reduced. Through the above structural design, the performance of the product meets the requirements and the cost is lower.

[0044] like Figure 1 or Figure 2 As shown, a second reinforcing rib 10 is provided on the outside of the end portion of the main pipe connector 1 and the side pipe connector 2. The second reinforcing rib 10 is located on the side of the tapered surface 11 close to the intersection 3. The second reinforcing rib 10 can improve the structural strength of the side pipe connector 2 and the main pipe connector 1. However, after the second reinforcing rib 10 is added, local stress may also exist inside it. Therefore, a groove structure 12 is further provided on the surface of the second reinforcing rib 10. The groove structure 12 can eliminate the stress inside the second reinforcing rib 10 while meeting the structural strength of the side pipe connector 2 and the main pipe connector 1.

[0045] The trough structure 12 includes a first trough 121 and a second trough 122. The first trough 121 and the second trough 122 are evenly distributed in an annular manner on the second reinforcing rib 10. The first trough 121 is larger than the second trough 122 and the first trough 121 and the second trough 122 are alternately distributed. The first trough 121 and the second trough 122 are not continuously distributed on the second reinforcing rib 10, which provides a guarantee for the reinforcing effect of the second reinforcing rib 10. At the same time, the alternating distribution of the first trough 121 and the second trough 122 ensures uniform strength distribution and stress in the second reinforcing rib 10, while also improving the aesthetic appearance of the tee pipe connection structure. While ensuring structural strength, the material used in the second reinforcing rib 10 is minimized, thereby achieving the goal of reducing costs.
