Description

Technical Field

[0001] This utility model relates to the field of concentric reducers, and particularly to impact-resistant concentric reducers. Background Technology

[0002] With the development of the times, people are using various pipes more and more widely. In order to facilitate the connection of pipe fittings of different diameters, the use of concentric reducers is essential.

[0003] To address this, patent CN201866431U discloses a concentric reducer. The technical solution is as follows: a concentric reducer, characterized by straight sections I and II at both ends of the conical section, with the pipe diameter at straight section I being larger than that at straight section II. In operation, straight section I is connected to the larger diameter pipeline, and straight section II is connected to the smaller diameter pipeline, and then they are welded together. The presence of straight sections facilitates welding, simplifies operation, and results in good weld formation, which is beneficial for non-destructive testing.

[0004] This utility model can be used to manufacture reducers with diameters up to DN2400;

[0005] The materials transported during the use of the aforementioned concentric reducers may impact and corrode their inner walls, while their outer walls may experience wear and liquid seepage into their interiors, causing contamination. This can affect the service life of the pipes and make it difficult to meet the actual usage requirements of the pipes. Utility Model Content

[0006] The purpose of this invention is to provide an impact-resistant concentric reducer to solve the problem of insufficient service life of existing concentric reducers.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an impact-resistant concentric reducer, comprising a pipe body and an mounting plate;

[0008] An installation plate is fixed to the bottom of the main body of the pipe, and an impact-resistant structure is provided on the inner wall of the main body of the pipe.

[0009] The impact-resistant structure includes an adhesive layer disposed on the inner wall of the pipe body, a toughness layer disposed on the inner wall of the adhesive layer, and a corrosion-resistant layer disposed on the inner wall of the toughness layer.

[0010] The mounting plate has uniformly spaced through holes inside, and mounting bolts are installed inside the through holes. A protective structure is provided on the outer wall of the pipe body.

[0011] Preferably, the toughening layer is a rare earth alloy steel.

[0012] Preferably, the corrosion-resistant layer is a wear-resistant alloy.

[0013] Preferably, the through holes are evenly distributed inside the pipe body, and the mounting bolts are threadedly connected to the through holes.

[0014] Preferably, the protective structure includes a waterproof layer disposed on the outer wall of the pipe body, a buffer layer disposed on the outside of the waterproof layer, and a wear-resistant layer disposed on the outside of the buffer layer.

[0015] Preferably, the waterproof layer is a zinc-plated layer.

[0016] Preferably, the wear-resistant layer is carbon steel.

[0017] The impact-resistant concentric reducer provided by this utility model has the following advantages:

[0018] By incorporating an impact-resistant structure, an adhesive layer, a toughening layer, and a corrosion-resistant layer are sequentially arranged on the inner wall of the pipeline body. The toughening layer is made of rare earth alloy steel, and the corrosion-resistant layer is made of wear-resistant alloy. This allows them to work together to improve impact resistance, and the innermost wear-resistant alloy can enhance corrosion resistance, thereby achieving the goal of improving the pipeline's impact resistance and corrosion resistance.

[0019] By incorporating a protective structure, a waterproof layer, a buffer layer, and a wear-resistant layer are sequentially installed on the outer wall of the main pipe. The waterproof layer is a galvanized layer, which helps prevent liquid from seeping into the interior of the pipe and causing contamination. The outermost wear-resistant layer is made of carbon steel, which increases the wear resistance of the device. This achieves the goal of improving the waterproof and wear-resistant performance of the device. Attached Figure Description

[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] Please see Figures 1-5 The impact-resistant concentric reducer provided by this utility model includes a pipe body 1 and a mounting plate 2.

[0028] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an installation plate 2 is fixed to the bottom end of the pipe body 1. An impact-resistant structure 3 is provided on the inner wall of the pipe body 1. The impact-resistant structure 3 includes an adhesive layer 301 provided on the inner wall of the pipe body 1, a toughness layer 302 provided on the inner wall of the adhesive layer 301, and a corrosion-resistant layer 303 provided on the inner wall of the toughness layer 302. The toughness layer 302 is rare earth alloy steel, and the corrosion-resistant layer 303 is wear-resistant alloy.

[0029] During the operation of concentric reducers, the items transported inside may cause corrosion damage or impact to the inner wall, thus damaging the pipe. To address this, an impact-resistant structure 3 is installed, in which a toughness layer 302 is adhered to the inner wall of the pipe body 1 via an adhesive layer 301. The toughness layer 302 is made of rare earth alloy steel, which effectively improves the pipe's fatigue resistance and impact toughness, thus providing a buffering effect when the pipe is subjected to impact. Furthermore, a wear-resistant alloy corrosion-resistant layer 303 is installed on the inner wall of the toughness layer 302, which further enhances the impact resistance of the toughness layer 302 while providing corrosion resistance, thereby preventing damage to the pipe when transporting corrosive items and greatly increasing the practicality of the device.

[0030] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the mounting plate 2 has through holes 4 evenly spaced inside, and mounting bolts 5 are installed inside the through holes 4. The through holes 4 are evenly spaced inside the pipe body 1. The mounting bolts 5 and the through holes 4 form a threaded connection. A protective structure 6 is provided on the outer wall of the pipe body 1. The protective structure 6 includes a waterproof layer 601 provided on the outer wall of the pipe body 1, a buffer layer 602 provided on the outside of the waterproof layer 601, and a wear-resistant layer 603 provided on the outside of the buffer layer 602. The waterproof layer 601 is a galvanized layer, and the wear-resistant layer 603 is carbon steel.

[0031] During the use and transportation of the pipeline, wear and tear may occur. Therefore, a protective structure 6 is provided, which includes a waterproof layer 601, which is actually a galvanized layer. This prevents water from seeping into the interior of the pipeline body 1 and contaminating the transported materials. Furthermore, a wear-resistant layer 603, made of carbon steel, is provided on the outermost side to improve the wear resistance of the pipeline. This prevents damage to the device during use and transportation caused by friction, thereby greatly increasing the practicality of the device.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
