Description

Technical Field

[0001] This utility model relates to the field of water supply steel pipe technology, specifically to an inner lining composite reinforcement structure for improving the toughness of water supply steel pipes. Background Technology

[0002] The composite reinforcement structure for improving the toughness of water supply steel pipes is a technical solution that enhances the overall performance of the pipe by adding a specific material layer to the inner wall. Its core lies in combining the advantages of different materials to significantly improve the crack resistance, corrosion resistance and toughness of the steel pipe while maintaining its original strength.

[0003] The existing water supply steel pipes have the problem that the inner lining structure lacks pressure resistance, which reduces the effectiveness of the inner lining layer.

[0004] The reason for this problem is that when water supply steel pipes are used outdoors, they need to be installed underground or supported by steel frames. In this case, the use of steel pipes will be affected by the external environment, and they are prone to corrosion and cracking. In order to reduce the wear and tear of steel pipes, a reinforcing inner lining layer is installed inside the steel pipe. However, when the reinforcing inner lining layer is compressed, it bears the same pressure as the steel pipe body. Therefore, the compressive resistance of the inside and outside of the steel pipe is similar, resulting in a lack of support and fixation effect against external pressure. Therefore, we propose a composite reinforcement structure for improving the toughness of water supply steel pipes. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes an inner lining composite reinforcement structure for improving the toughness of water supply steel pipes, which solves the problem that the existing water supply steel pipe inner lining structure lacks pressure resistance, resulting in a reduction in the performance of the inner lining layer.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: a composite reinforcement structure for improving the toughness of water supply steel pipes, comprising a steel pipe body, an inner lining mechanism provided inside the steel pipe body, the inner lining mechanism comprising an inner lining tube disposed inside the steel pipe body, the inner lining tube being used to increase the fixing effect of the steel pipe body, a fixing ring disposed outside the inner lining tube, the fixing ring being used to increase the external support effect of the inner lining tube, and pressure-resistant rings disposed on both sides of the fixing ring, the pressure-resistant rings being disposed outside the inner lining tube, the pressure-resistant rings increasing the pressure resistance effect on the inner lining tube through inclined surfaces.

[0007] Preferably, the inner liner tube has a connecting tube inside, and the connecting tube has an inner protective layer inside.

[0008] Preferably, mounting rings are provided on both sides of the fixing ring, and the compression ring is fixedly connected to the side of the mounting ring.

[0009] Preferably, an abutment ring is sleeved on the outside of the mounting ring, a reinforcing tube is sleeved on the outside of the abutment ring, the main body of the steel pipe is disposed outside the reinforcing tube, and the reinforcing tube is disposed outside the fixing ring.

[0010] Preferably, the steel pipe body is provided with an outer protective layer.

[0011] The beneficial effects of this utility model are:

[0012] The technical solution of this utility model uses both the inner and outer protective layers as anti-corrosion layers, which can effectively protect the inner and outer contact surfaces of the steel pipe from corrosion. The inner lining increases the overall hardness of the steel pipe. The fixing ring is provided with mounting rings on both sides, and the pressure-resistant ring is set between the fixing ring and the mounting ring. The pressure-resistant ring is an inclined ring, so that the support point and the two sides are triangular points. The abutment ring increases the connection effect between the mounting ring and the reinforcing pipe. By setting the pressure-resistant ring between the fixing ring and the mounting ring, the inclined setting of the pressure-resistant ring increases the pressure resistance on both sides of the pressure-resistant ring, thereby increasing the overall pressure resistance of the steel pipe and reducing the external pressure burden on other functional layers.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides an inner lining composite reinforcement structure for improving the toughness of water supply steel pipes, which solves the problem that the existing water supply steel pipes have a lack of compressive strength in the inner lining structure, resulting in a reduced performance of the inner lining layer.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] According to the appendix Figure 1 - Figure 5 As shown, the device includes a steel pipe body 1, and an inner lining mechanism is provided inside the steel pipe body 1. The inner lining mechanism includes an inner lining tube 2, which is disposed inside the steel pipe body 1. The inner lining tube 2 is used to increase the fixing effect of the steel pipe body 1. A fixing ring 207 is disposed outside the inner lining tube 2. The fixing ring 207 is used to increase the external support effect of the inner lining tube 2. A pressure-resistant ring 203 is disposed on both sides of the fixing ring 207. The pressure-resistant ring 203 is disposed outside the inner lining tube 2. The pressure-resistant ring 203 increases the pressure resistance effect on the inner lining tube 2 through its inclined surface.

[0024] The inner liner 2 has a connecting pipe 204 inside, and an inner protective layer 205 inside the connecting pipe 204. Mounting rings 206 are provided on both sides of the fixing ring 207. The pressure-resistant ring 203 is fixedly connected to the side of the mounting ring 206. A retaining ring 202 is sleeved on the outside of the mounting ring 206. A reinforcing pipe 101 is sleeved on the outside of the retaining ring 202. The steel pipe body 1 is set outside the reinforcing pipe 101. The reinforcing pipe 101 is set outside the fixing ring 207. An outer protective layer 201 is provided on the outside of the steel pipe body 1.

[0025] By placing the inner protective layer 205 at the innermost part of the steel pipe and the outer protective layer 201 at the outermost part, both the inner and outer protective layers 205 and 201 serve as anti-corrosion layers, effectively protecting the inner and outer contact surfaces of the steel pipe from corrosion. The inner liner 2 is a relatively rigid support pipe, primarily increasing the overall rigidity of the steel pipe. Mounting rings 206 are located on both sides of the fixing ring 207, and a pressure-resistant ring 203 is positioned between the fixing ring 207 and the mounting rings 206. The pressure-resistant ring 203 is an inclined ring, creating a triangular point between the support point and the two sides, increasing the compressive strength of the two sides of the pressure-resistant ring 203. The pressure-resistant ring 203 can withstand greater pressure, thereby increasing the overall pressure resistance of the steel pipe and reducing the external pressure burden on other functional layers. The abutment ring 202 is set outside the mounting ring 206, thereby increasing the connection effect between the mounting ring 206 and the reinforcing pipe 101. At the same time, the mounting ring 206 and the fixing ring 207 provide support for the steel pipe. By setting the pressure-resistant ring 203 between the fixing ring 207 and the mounting ring 206, the inclined setting of the pressure-resistant ring 203 increases the pressure resistance on both sides of the pressure-resistant ring 203, thereby increasing the overall pressure resistance of the steel pipe and reducing the external pressure burden on other functional layers.

[0026] In summary, compared with existing technologies, it has the following beneficial effects:

[0027] With both the inner protective layer 205 and the outer protective layer 201 being anti-corrosion layers, the inner and outer contact surfaces of the steel pipe can be effectively protected against corrosion. The inner liner 2 increases the overall hardness of the steel pipe. The fixing ring 207 is provided with mounting rings 206 on both sides. The pressure-resistant ring 203 is located between the fixing ring 207 and the mounting ring 206. The pressure-resistant ring 203 is an inclined ring, so that the support point and the two sides are triangular points. The abutment ring 202 increases the connection effect between the mounting ring 206 and the reinforcing pipe 101. By setting the pressure-resistant ring 203 between the fixing ring 207 and the mounting ring 206, the inclined setting of the pressure-resistant ring 203 increases the pressure resistance on both sides of the pressure-resistant ring 203, thereby increasing the overall pressure resistance of the steel pipe and reducing the external pressure burden on other functional layers.
