Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pipe connection components, and in particular relates to the outlet bend of a water pump. Background Technology
[0002] Pipe fittings are an indispensable component of industrial and building piping systems. They act as the "joints" of the system, responsible for tightly and reliably connecting straight pipes, elbows, valves, and other components into a complete transport network. Their core function is to ensure the safe, sealed, and leak-free transmission of fluids or gases in complex pipelines, while allowing necessary disassembly and maintenance. They are key to ensuring the efficient and stable operation of the entire system.
[0003] Pump outlet elbow joints are mainly used to change the direction of delivery and are adapted to pump and pipeline layout. In order to ensure strength, most traditional elbow joints are made of metal casting. Although the strength meets the standard, the cost is high, the weight is large, and it is prone to corrosion.
[0004] To address the aforementioned issues, this application proposes a water pump outlet bend. Utility Model Content
[0005] The purpose of this invention is to provide a water pump outlet bend, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a water pump outlet bend, comprising a pipe body and a flange. The bend is integrally injection molded. The pipe body includes a bent portion and straight portions formed at both ends of the bent portion. A first reinforcing rib is formed on the outer surface of the straight portion away from the bent portion. A second reinforcing rib is formed on the middle of the outer surface of the bent portion. A third reinforcing rib is formed between one second reinforcing rib and two first reinforcing ribs along the axial direction of the pipe body. The third reinforcing rib has several circumferentially evenly arranged ribs.
[0008] Furthermore, a frustum is formed between the first reinforcing rib and the pipe body, and a support block is also formed between the first reinforcing rib and the flange. The number of support blocks is the same as that of the third reinforcing rib and they correspond to each other along the axial direction.
[0009] Furthermore, a support plate is formed at the included angle on the outer surface of the tube, and the two ends of the support plate are respectively connected to two flanges.
[0010] Furthermore, the support block is triangular.
[0011] Furthermore, a boss is formed at the end of the flange away from the pipe body.
[0012] Furthermore, the flange is formed with circumferentially arranged connecting holes, which are spaced apart from the third reinforcing rib.
[0013] This utility model has the following beneficial effects:
[0014] This utility model adopts injection molding, which greatly reduces the overall cost and makes it lightweight. At the same time, the third reinforcing rib set along the circumference of the tube body plays a role in resisting torsion. With the first and second reinforcing ribs connected at the same time, the resistance to torsion and deformation is further enhanced, and the overall strength of the bent tube is improved.
[0015] This invention provides a support plate at the included angle of the pipe body and flange connection. The support plate effectively supports the overall shape of the bend and prevents angular deformation after installation.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] 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 scope of protection of the present utility model.
[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a water pump outlet bend, including a pipe body 1 and a flange 2. The bend is integrally injection molded. The mold is filled with filler to fill the inside of the bend. The mold outer wrapping part is respectively provided with a forming support plate 3, a first reinforcing rib 4, a second reinforcing rib 5, a third reinforcing rib 6, a cone 7, and a support block 8.
[0027] The pipe body 1 includes a curved portion 12 and straight portions 11 formed at both ends of the curved portion 12. A first reinforcing rib 4 is formed on the outer surface of the straight portion 11 away from the curved portion 12. A second reinforcing rib 5 is formed on the middle of the outer surface of the curved portion 12. A third reinforcing rib 6 is formed along the axial direction of the pipe body 1 between one second reinforcing rib 5 and two first reinforcing ribs 4. The third reinforcing rib 6 has several circumferentially evenly arranged ribs. In this embodiment, the first reinforcing ribs 4, the second reinforcing ribs 5, and the third reinforcing ribs 6 interact to form a mesh-like wrapping on the surface of the pipe body 1, thereby improving the overall strength of the curved pipe.
[0028] A frustum 7 is formed between the first reinforcing rib 4 and the pipe body 1. A support block 8 is also formed between the first reinforcing rib 4 and the flange 2. The number of support blocks 8 is the same as that of the third reinforcing rib 6 and they correspond to each other along the axial direction. In this embodiment, the third reinforcing rib 6 is connected to the support block 8, and then the support block 8 supports the flange 2, thereby forming further stability between the two flanges 2.
[0029] Furthermore, a support plate 3 is formed at the included angle on the outer surface of the pipe body 1. The two ends of the support plate 3 are respectively connected to two flanges 2, and the support plate 3 strengthens the connection between the pipe body 1 and the flanges 2.
[0030] To further increase the structural strength at the connection between pipe body 1 and flange 2, support block 8 is triangular.
[0031] Furthermore, to ensure the sealing of the connection between the bend and the external pipe flange, a boss 21 is formed on the end of the flange 2 away from the pipe body 1. When the pipes are actually connected, there is a sealing gasket at the connection, corresponding to the boss 21, to ensure that the sealing is evenly pressurized.
[0032] Furthermore, the flange 2 is formed with circumferentially arranged connecting holes 22, which are spaced apart from the third reinforcing rib 6. By setting them at intervals, the force can be distributed more evenly, thereby making the overall performance of the flange 2 more stable.
[0033] It is understood that this utility model enhances the torsional and deformation resistance by using a third reinforcing rib on the outer circumference of the pipe body in conjunction with the first and second reinforcing ribs, and provides a support plate on the inner side of the connection between the pipe body and the flange to effectively support the bent pipe structure, prevent angular deformation, and improve the overall strength of the bent pipe.
