Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline equipment technology, and more specifically, to a graphite composite internal ribbed tube structure. Background Technology
[0002] Internally ribbed pipes are pipe fittings used to enhance the internal structural strength and pressure resistance of pipelines. They are usually installed inside pipelines to improve the load-bearing capacity and corrosion resistance of pipelines by increasing the pipe wall thickness or pipeline strength. Internally ribbed pipes are widely used in industries such as petroleum, chemical, and water treatment, especially in pipeline systems that transport high-pressure fluids or corrosive media.
[0003] Operators often use ribbed tubes when transporting high-pressure or corrosive fluids to ensure the safety of fluid transport. However, while existing ribbed tubes have basic transport functions, irregular flow of fluid in the electric field can cause potential changes in the tube when passing through high-potential areas such as high-voltage power stations. This can easily generate static electricity in the pipe, potentially leading to static fires when transporting flammable fluids. Therefore, improvements are needed. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a graphite composite internal ribbed tube structure, which has the advantage of isolating external electric fields.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a graphite composite inner ribbed tube structure, comprising a ribbed tube shell, a first conductive ring fixedly connected to the right side of the inner surface of the ribbed tube shell, a second conductive ring fixedly connected to the left side of the inner surface of the ribbed tube shell, the positions of the first and second conductive rings being symmetrical about the ribbed tube shell, and a metal mesh fixedly connected to the inner surface between the first and second conductive rings, the metal mesh being made of copper wire.
[0006] As a preferred embodiment of this utility model, an outer plastic layer located inside the ribbed tube shell is fixedly sleeved on the outer surface of the metal mesh, and an inner plastic layer is fixedly sleeved on the inner surface of the metal mesh.
[0007] As a preferred technical solution of this utility model, interface tubes are fixedly connected to both the left and right sides of the rib tube shell, and a composite inner lining layer is fixedly sleeved on the inner surface of the interface tube. The outer surface of the composite inner lining layer is fixedly connected to the inner surface of the rib tube shell, the first conductive ring, the second conductive ring and the inner plastic layer, respectively.
[0008] As a preferred embodiment of this utility model, a hollow ring is fixedly connected to the outer surface of the ribbed tube shell, and a rubber layer is fixedly connected to the outer surface of the hollow ring.
[0009] As a preferred embodiment of this utility model, a metal ring is fixedly connected to the inner surface of the hollow ring, which is located between the ribbed outer shell and the rubber layer, and the inner surface of the metal ring is fixedly connected to the outer surface of the ribbed outer shell.
[0010] As a preferred embodiment of this utility model, a V-shaped plate is fixedly connected to the inner surface of the hollow ring, a metal plate is fixedly connected to the inner surface of the V-shaped plate, and the metal plate is fixedly connected to the outer surface of the ribbed tube shell.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model, by setting up a ribbed outer shell, a first conductive ring, a second conductive ring, a metal mesh, and a composite inner lining layer, uses the mesh design of the metal mesh as an equivalent metal shielding mesh, while the outer graphite layer of the composite inner lining layer can serve as a grounding point. When the entire ribbed outer shell is in an electric field, the metal mesh and the composite inner lining layer will form an equipotential body, making the potential of all parts inside the metal mesh the same. The electromagnetic radiation from the surrounding environment and the electromagnetic signals emitted by other devices will be isolated on the outside of the metal mesh, thereby ensuring that the inside of the metal mesh is not affected by the external electric field and avoiding fire or discharge caused by fluid flowing at different potential positions.
[0013] 2. This utility model, by setting a hollow ring, a metal ring, a rubber layer, a V-shaped plate and a metal plate, and the design of the rubber layer, can reduce the external impact on the rib tube shell to a certain extent. The design of the hollow ring, the metal ring, the V-shaped plate and the metal plate can greatly enhance the internal and external ultimate pressure that the rib tube shell can withstand. This not only improves the carrying capacity of the rib tube shell for different fluids, but also improves the maximum external pressure limit of the rib tube shell. Attached Figure Description

[0021] 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.
[0022] like Figures 1 to 6 As shown, this utility model provides a graphite composite inner ribbed tube structure, including a ribbed tube shell 1. A first conductive ring 2 is fixedly connected to the right side of the inner surface of the ribbed tube shell 1, and a second conductive ring 3 is fixedly connected to the left side of the inner surface of the ribbed tube shell 1. The positions of the first conductive ring 2 and the second conductive ring 3 are symmetrical about the ribbed tube shell 1. A metal mesh 4 is fixedly connected to the inner surface between the first conductive ring 2 and the second conductive ring 3. The metal mesh 4 is made of copper wire.
[0023] The mesh design of the metal mesh 4 acts as a Faraday cage, which can be used to isolate the complex electric field of the surrounding environment and the high potential environment around other high voltage power equipment, and ensure that the potential inside the metal mesh 4 remains stable.
[0024] The outer surface of the metal mesh 4 is fixedly fitted with an outer plastic layer 5 located inside the rib tube shell 1, and the inner surface of the metal mesh 4 is fixedly fitted with an inner plastic layer 6.
[0025] The outer plastic layer 5 and the inner plastic layer 6 can protect the metal mesh 4.
[0026] Among them, interface tubes 7 are fixedly connected to both the left and right sides of the rib tube shell 1. A composite inner lining layer 8 is fixedly sleeved on the inner surface of the interface tube 7. The outer surface of the composite inner lining layer 8 is fixedly connected to the inner surface of the rib tube shell 1, the first conductive ring 2, the second conductive ring 3 and the inner plastic layer 6 respectively.
[0027] The inner and outer surfaces of the composite inner lining layer 8 are covered with a graphite material layer, which can not only serve as a protective grounding function, but also improve the overall corrosion resistance of the ribbed outer shell 1.
[0028] Among them, a hollow ring 9 is fixedly connected to the outer surface of the rib tube shell 1, and a rubber layer 11 is fixedly connected to the outer surface of the hollow ring 9.
[0029] The design of the hollow ring 9 and the metal ring 10 can provide overall protection for the ribbed outer shell 1.
[0030] Among them, a metal ring 10 located between the ribbed outer shell 1 and the rubber layer 11 is fixedly connected to the inner surface of the hollow ring 9, and the inner surface of the metal ring 10 is fixedly connected to the outer surface of the ribbed outer shell 1.
[0031] The design of the metal ring 10 can improve the overall pressure resistance of the ribbed outer shell 1.
[0032] Among them, a V-shaped plate 12 is fixedly connected to the inner surface of the hollow ring 9, a metal plate 13 is fixedly connected to the inner surface of the V-shaped plate 12, and the metal plate 13 is fixedly connected to the outer surface of the rib tube shell 1.
[0033] The triangular design of the V-shaped plate 12 and the metal plate 13 provides stability and can significantly improve the compressive strength of the hollow ring 9 and the ribbed outer shell 1 when subjected to pressure from both the inside and outside.
[0034] Working principle and usage process of this utility model:
[0035] The design of the hollow ring 9 and the metal ring 10, as well as the triangular design of the V-shaped plate 12 and the metal plate 13, greatly enhances the internal and external ultimate pressure that the ribbed tube shell 1 can withstand. This not only increases the liquid pressure that the ribbed tube shell 1 can withstand, but also increases the maximum pressure limit that the ribbed tube shell 1 can withstand when subjected to external pressure.
[0036] When the inner rib tube passes through a high potential environment, the mesh design of the metal mesh 4 will form equipotential bodies inside the metal mesh 4. This makes the potential of each part inside the metal mesh 4 consistent. At this time, when the fluid inside the rib tube shell 1 flows through the inside of the metal mesh 4, the potential change inside the metal mesh 4 will not be caused by the irregular flow of the fluid, thus ensuring the safety of the dangerous fluid during transportation.
