Description

Technical Field

[0001] The utility model belongs to the technical field of seamless steel pipes, and particularly relates to a corrosion-resistant epoxy glass high-pressure pipeline. Background Art

[0002] At present, the seamless steel pipes used in existing liquid transportation pipelines are all made of stainless steel. Under the high-speed impact of the fluid, friction occurs between the fluid and the steel pipe, reducing the service life of the stainless steel pipeline and thus causing the stainless steel to break.

[0003] In actual fluid transportation, the high-speed random movement will cause inevitable damage to the inner wall surface of the steel pipe. At the same time, when transporting the fluid, it will form a large resistance by rubbing against the inner wall surface of the steel pipe, thereby greatly reducing the actual service life of the steel pipe and being unfavorable for the long-term use of the steel pipe. Therefore, it is necessary to set a liquid film on the inner wall surface of the steel pipe to slow down the flow rate of the fluid, so as to slow down the impact wear of the inner wall surface of the steel pipe and indirectly improve the corrosion resistance and long-term use characteristics of the steel pipe. Summary of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract of the specification and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0005] In view of the problem in the above or existing technologies that the excessive fluid flow rate in the steel pipe leads to easy corrosion and wear of the steel pipe and is not suitable for the long-term transportation of the steel pipe, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a corrosion-resistant epoxy glass high-pressure pipeline.

[0007] To solve the above technical problems, the present utility model provides the following technical solutions:

[0008] As a preferred scheme of the corrosion-resistant epoxy glass high-pressure pipeline of the present utility model, wherein: an epoxy glass pipe, and a retention liquid film is adhesively attached to the inner wall surface of the epoxy glass pipe through adhesive blocks, and the center of the retention liquid film coincides with the center of the circle of the epoxy glass pipe;

[0009] The retention liquid film includes a first curved surface, a slope surface is fitted and connected to the outer edge of the first curved surface, a bottom buffer surface is fixedly arranged on the inner wall surface of the slope surface, a second curved surface is fitted on the top of the bottom buffer surface, and a through-flow surface is fixedly attached to the joint seam of the bottom buffer surface and the edge of the second curved surface, and the center of the inner wall of the through-flow surface is aligned with the center of the inner wall of the first curved surface.

[0010] As a preferred embodiment of the corrosion-resistant epoxy glass high-pressure pipeline of the present utility model, the following is provided: A flange is fixedly connected to the end face of the epoxy glass tube, and bolts are penetratingly connected to the flange. A plurality of bolts are provided, and the plurality of bolts are annularly arrayed on the side wall surface of the flange.

[0011] As a preferred embodiment of the corrosion-resistant epoxy glass high-pressure pipeline of the present utility model, the following is provided: A carbon steel fiber layer is fixed on the outer wall surface of the epoxy glass tube, a corundum layer is fixed on the outer wall surface of the carbon steel fiber layer, and a manganese steel fiber layer is embedded on the outer wall surface of the corundum layer.

[0013] As a preferred embodiment of the corrosion-resistant epoxy glass high-pressure pipeline of the present utility model, the following is provided: The structure of the retention liquid film is set as a double-opening curved film sheet, and the bending radian of the bottom buffer surface is smaller than the top bending radian of the second curved surface.

[0014] As a preferred embodiment of the corrosion-resistant epoxy glass high-pressure pipeline of the present utility model, the following is provided: The centers of the carbon steel fiber layer, the corundum layer, and the manganese steel fiber layer all coincide with the center of the epoxy glass tube.

[0015] As a preferred embodiment of the corrosion-resistant epoxy glass high-pressure pipeline of the present utility model, the following is provided: Two flanges are provided, and the two flanges are symmetrically arranged on the outer wall surface of the epoxy glass tube.

[0016] The beneficial effects of a corrosion-resistant epoxy glass high-pressure pipeline of the present utility model are as follows: The retention liquid film provided inside the epoxy glass tube causes the fluid to encounter resistance when it meets the retention liquid film. The first curved surface, the bottom buffer surface, and the second curved surface are fitted on the retention liquid film, which can help the fluid to significantly slow down the flow rate after encountering multiple curved surfaces.

Obviously, the following drawings are only some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts. Among them:

[0021] Figure 4 is Figure 3 the enlarged view of part A in Specific Embodiments

[0022] To make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0025] Embodiment 1: Referring to Figure 1 and 2 , this is the first embodiment of the present utility model, and this embodiment provides a component that can provide an effect of reducing the fluid flow rate inside the epoxy glass tube.

[0026] Specifically, for the epoxy glass tube 100, a retained liquid film 700 is adhesively attached to the inner wall surface of the epoxy glass tube 100 through adhesive blocks, and the center of the retained liquid film 700 coincides with the center of the circle of the epoxy glass tube 100;

[0027] The retained liquid film 700 includes a first curved surface 701. A slope surface 702 is fitted and connected to the outer edge of the first curved surface 701. A bottom buffer surface 703 is fixedly arranged on the inner wall surface of the slope surface 702. A second curved surface 704 is fitted on the top of the bottom buffer surface 703. A through-flow surface 705 is fixedly attached to the joint seam of the edge of the bottom buffer surface 703 and the second curved surface 704. The center of the inner wall of the through-flow surface 705 is aligned with the center of the inner wall of the first curved surface 701.

[0028] Among them, the viscous fitting of the retention liquid film 700 enables the fluid to be significantly reduced in flow velocity and the impact force to be weakened and dispersed after contacting the retention liquid film 700 due to the diversion of the curved surface structures of the first curved surface 701, the slope surface 702, the bottom buffer surface 703, and the second curved surface 704 in the retention liquid film 700, indirectly weakening the erosion effect on the inner wall surface of the epoxy glass tube 100. The alignment of the flow-through surface 705 with the first curved surface 701 can provide a communication channel for the fluid to help the fluid be directly transported.

[0029] Further, the structure of the retention liquid film 700 is set as a double-opening curved film sheet, and the bending radian of the bottom buffer surface 703 is relatively gentle, and the top bending radian of the second curved surface 704 is set relatively steep.

[0030] Among them, the double-opening setting of the retention liquid film 700 enables the flow velocity to be smoothly transported without affecting the transportation efficiency; the gentle angle of the bottom buffer surface 703 can help the fluid to be temporarily accumulated under the action of gravity, slowing down the impact effect of the fluid; the steep bending radian of the second curved surface 704 enables the accumulated fluid located on the bottom buffer surface 703 to be transported in time to avoid affecting the transportation efficiency.

[0031] In summary, by using multiple curved surface structures in the retention liquid film 700, the flow velocity impact of the fluid is slowed down, thereby reducing the corrosion effect on the epoxy glass tube 100, and the retention liquid film 700 is a permeable membrane component that does not affect the normal transportation process of the fluid. The structural zoning of this component greatly improves the service life of the epoxy glass tube 100.

[0032] Example 2: Refer to Figure 2 and 4 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a support and protection component for the outer wall of the tube.

[0033] Specifically, a carbon steel fiber layer 400 is fixed on the outer wall surface of the epoxy glass tube 100, a corundum layer 500 is fixed on the outer wall surface of the carbon steel fiber layer 400, and a manganese steel fiber layer 600 is embedded on the outer wall surface of the corundum layer 500.

[0034] Specifically, the centers of the carbon steel fiber layer 400, the corundum layer 500, and the manganese steel fiber layer 600 all coincide with the center of the epoxy glass tube 100.

[0035] Specifically, the structural strength of the corundum layer 500 is stronger than that of the carbon steel fiber layer 400 and the manganese steel fiber layer 600.

[0036] Among them, the carbon fiber layer 400, the corundum layer 500 and the manganese steel fiber layer 600 are arranged on the outer wall surface of the epoxy glass tube 100, which can provide long-term and lasting protection for the epoxy glass tube 100 to avoid external bumps on the glass tube; the corundum layer 500 is embedded between the carbon steel fiber layer 400 and the manganese steel fiber layer 600, which can provide an intermediate support for the two fiber layers, making the combined support and protection effect of the fiber layers more compact.

[0037] Specifically, a flange 200 is fixedly connected to the end face of the epoxy glass tube 100, and a bolt 300 is connected through the flange 200. A plurality of bolts 300 are provided, and the plurality of bolts 300 are annularly arrayed on the side wall surface of the flange 200.

[0038] Specifically, two flanges 200 are provided, and the two flanges 200 are symmetrically arranged on the outer wall surface of the epoxy glass tube 100.

[0039] Among them, the combination of the flange 200 and the bolt 300 makes the end face of the epoxy glass tube 100 more stable, avoiding the shaking of the glass tube caused by the impact of high-speed fluid.

[0040] In summary, the layered fixation of multiple groups of fiber layers and corundum layers can help the outer wall surface of the glass tube receive better support, and at the same time, the reinforcement and fixation of the flange and bolts can provide stability for the glass tube during fluid transportation. The combination of these components avoids the glass tube from being affected by excessive physical external forces and ensures the integrity of the external structure of the glass tube.
