Description

Technical Field

[0001] The utility model relates to the technical field of double-wall corrugated pipes, in particular to a corrosion-resistant enhanced double-wall corrugated pipe. Background Art

[0002] The production process of double-wall corrugated pipes mainly relies on plastic materials such as high-density polyethylene (HDPE). Although the material has certain corrosion resistance, in scenarios where it needs to be buried underground or used underwater for a long time, the connection gaps of the double-wall corrugated pipes are easily corroded. At present, hot-melt connection is usually used in the installation process of double-wall corrugated pipes. The installation process requires a lot of time and cost to hot-melt the double-wall corrugated pipes, and then they need to be spliced. The wall thickness of the double-wall corrugated pipe changes at the hot-melt point, and it is easy to deform due to extrusion, causing the inner wall of the double-wall corrugated pipe connection to bulge, thereby reducing the effective flow area of ​​the pipeline and increasing the resistance of the fluid through.

[0003] To this end, we propose a corrosion-resistant reinforced double-wall corrugated pipe. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example

[0020] See also Figure 1-Figure 4The figure shows a corrosion-resistant reinforced double-wall corrugated pipe, including a bellows body 1, an inlay groove 101 is provided on the inner wall of one end of the bellows body 1, and a connecting block 102 is provided at the other end of the bellows body 1. The inlay groove 101 is fixedly connected to a sealing mechanism 2, and the sealing mechanism 2 includes a base 201 and a limit block 202. The limit block 202 is snap-fitted with the connecting block 102, and a reinforcement layer 103 is provided on the outside of the bellows body 1. The utility model realizes a fast and stable connection between pipes by snap-fitting the base and the limit block in the sealing mechanism inside the inlay groove of the bellows body with the connecting block at the other end of the bellows body, which can effectively avoid the problems of wall thickness change and extrusion deformation in the traditional hot melt connection process, thereby ensuring the flatness and sealing of the pipe connection.

[0021] Furthermore, a barb block 104 is provided at one end of the connecting block 102, and the barb block 104 is snap-fitted with the limit block 202. Due to the snap-fit ​​design of the barb block and the limit block, during installation, only the two need to be aligned and gently pushed in to achieve a quick connection, and at the same time, sealing is performed to reduce the impact of hot melting on the pipeline.

[0022] Furthermore, one end of the limit block 202 is rotatably connected to the inner wall of the base 201, and the other end of the limit block 202 is provided with a conical connecting block 203. Through the rotating connection design between the limit block and the base, the pipeline can better cooperate with the connecting block and the barb block during the installation process, ensuring the tightness and stability of the pipeline connection.

[0023] Furthermore, a filling extrusion is provided inside the base 201, and the filling extrusion is a sealing extrusion. The inner wall of the base 201 is made of rubber. The sealing extrusion filled inside the base is matched with the conical connecting block in the limit block, so that when it is squeezed during the connection process, the sealant overflows and fills the entire sealing mechanism, thereby forming a sealing effect.

[0024] Furthermore, the inner wall of the base 201 is provided with a plurality of limit blocks 202 at equal intervals in a circular shape. Since the limit blocks are evenly distributed on the inner wall of the base, when the bellows body is connected to the base, each limit block can evenly withstand the pressure from the bellows body, making the pipeline connection more stable and effectively preventing the connection from loosening or deformation due to uneven pressure.

[0025] Furthermore, the limit block 202 is an inclined surface, and the limit block with an inclined surface can provide a certain guiding effect during installation, so that the bellows body can slide into the base more easily, thereby achieving a quick and stable connection.

[0026] In this solution, the workflow is as follows: first, fix the base of the sealing mechanism in a predetermined position to ensure that the base is stable and accurately positioned, and check whether there is a filling extrusion inside the base. At the same time, check whether the filling extrusion is solidified in any place for easy replacement; then align one end of the bellows body with the installed base. This process is the cooperation of the connecting block at one end of the bellows body and the multiple limit blocks on the inner wall of the base. Since the limit blocks are arranged in a circular shape with equal spacing and are inclined surfaces, they help guide the connecting block to slide in smoothly. During this process, the barbed block at one end of the connecting block will form a tight snap fit with the limit block. At the same time, the conical connecting block at the other end of the limit block will also play a role in auxiliary positioning and fixing, and squeeze the filling extrusion to fill the inner wall of the base.
