Description

Technical Field

[0001] This utility model relates to the field of plastic pipe technology, and in particular to a carbon black PE pipe for water supply with high aging resistance. Background Technology

[0002] PE pipes, or polyethylene pipes, are tubular products made from polyethylene (PE) as the main raw material through processes such as extrusion molding. They are widely used in water supply, drainage, gas transmission, agricultural irrigation and other fields.

[0003] However, traditional PE pipes have some shortcomings in long-term use. When operators splice and install two PE pipes, the sealing performance is relatively poor, which can easily cause liquid leakage during use. Some operators use heat fusion treatment at the splice, but after long-term use, the seal may fail due to thermal expansion and contraction, and it is not effective in sealing the connection between two PE pipes. In order to solve the above problems, a high-aging-resistant carbon black PE pipe for water supply is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a carbon black PE pipe for water supply with high aging resistance, so as to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a high-aging-resistant carbon black PE pipe for water supply, comprising a first PE pipe and a second PE pipe, a sealing structure provided between the first PE pipe and the second PE pipe, a sealing protrusion ring fixedly installed on the outer wall of one end of the first PE pipe, a sealing rubber ring provided inside one end of the second PE pipe, and a sealing gasket provided on the outside of the sealing rubber ring, the sealing structure comprising a first locking sleeve and a second locking sleeve, an installation block fixedly installed on one end of each of the first locking sleeve and the second locking sleeve, a locking screw inserted into the two installation blocks, and a locking cap provided on the outer wall of the locking screw.

[0006] As a preferred embodiment of the above technical solution, a sealing groove is provided inside one end of the second PE pipe, and the sealing ring and the sealing gasket are fixedly fitted together, with both the sealing ring and the sealing gasket installed inside the sealing groove.

[0007] As a preferred embodiment of the above technical solution, the sealing convex ring is adapted to the size of the sealing groove, and the inner walls of the first locking sleeve and the second locking sleeve are both fixedly fitted with sealing sleeves. The sealing sleeves are fitted at the connection gap of the two PE pipes. One end of the first locking sleeve is fixedly installed with a limit rod, and one end of the second locking sleeve is rotatably installed on the outer wall of the limit rod.

[0008] As a preferred embodiment of the above technical solution, one end of the locking screw is fixedly connected to an anti-slip knob, the first locking sleeve and the second locking sleeve are sized to match, and the locking cap is threadedly connected to the outer wall of the locking screw and located outside one of the mounting blocks.

[0009] As a preferred embodiment of the above technical solution, the innermost layer of both the first PE pipe and the second PE pipe is made of food-grade high-density polyethylene, the middle layer is made of glass fiber reinforced polyethylene mesh, and the outermost layer of both the first PE pipe and the second PE pipe is made of aging-resistant polyethylene.

[0010] As a preferred embodiment of the above technical solution, the inner and outer walls of the fiberglass reinforced polyethylene mesh are provided with hot melt adhesive, which is tightly bonded to the inner and outer layers.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model device is equipped with a sealing structure. The sealing ring at one end of the first PE pipe is inserted into the sealing groove inside the second PE pipe, so that the sealing ring squeezes the sealing gasket and sealing rubber ring in the sealing groove to facilitate the initial sealing of the two PE pipes. Then, the first locking sleeve and the second locking sleeve are placed at the joint of the two PE pipes, so that the sealing sleeves on the inner walls of the two locking sleeves further seal the joint. Then, the anti-slip knob drives the locking screw to be inserted into the two mounting blocks. Finally, the locking cap is used to limit and fix it, which facilitates the relative sealing of the two PE pipes during splicing and installation, improves the sealing effect and avoids leakage. It avoids the problems of thermal expansion and contraction leading to sealing failure caused by traditional hot melt splicing, and achieves reliable sealing and tight installation of the two PE pipes.

[0013] Simultaneously, a three-layer composite structure design is adopted. The outer layer, through the synergistic effect of scientifically proportioned carbon black, antioxidants, and light stabilizers, significantly improves the pipe's resistance to ultraviolet aging and heat aging. The middle reinforcing layer, made of glass fiber reinforced polyethylene mesh, effectively improves the pipe's mechanical strength, impact resistance, and creep resistance, making the pipe less prone to damage under high-pressure water transmission, underground laying, or external loads, thus balancing aging resistance and structural stability. The inner layer uses food-grade high-density polyethylene, ensuring the hygiene and safety of the water transmission process, meeting the hygiene standards for water supply pipes, and avoiding secondary pollution of water bodies.

It should be understood that the embodiments of the present invention are not limited in scope.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown in the figure, this embodiment provides a high-aging-resistant carbon black PE pipe for water supply, including a first PE pipe 1 and a second PE pipe 2. A sealing structure 3 is provided between the first PE pipe 1 and the second PE pipe 2. A sealing protrusion ring 11 is fixedly installed on the outer wall of one end of the first PE pipe 1. A sealing rubber ring 22 is provided inside one end of the second PE pipe 2. A sealing gasket 23 is provided on the outside of the sealing rubber ring 22. The sealing structure 3 includes a first locking sleeve 31 and a second locking sleeve 32. An installation block 35 is fixedly installed on one end of both the first locking sleeve 31 and the second locking sleeve 32. A locking screw 37 is inserted into the two installation blocks 35. A locking cap 38 is provided on the outer wall of the locking screw 37.

[0023] like Figures 2 to 3As shown, a sealing groove 21 is provided inside one end of the second PE pipe 2. The sealing ring 22 and the sealing gasket 23 are fixedly fitted together and installed inside the sealing groove 21. The sealing convex ring 11 is adapted to the size of the sealing groove 21. The inner walls of the first locking sleeve 31 and the second locking sleeve 32 are fixedly fitted with sealing sleeves 34. The sealing sleeves 34 are fitted at the joint of the two PE pipes. One end of the first locking sleeve 31 is fixedly installed with a limit rod 33. One end of the second locking sleeve 32 is rotatably installed on the outer wall of the limit rod 33. One end of the locking screw 37 is fixedly connected with an anti-slip knob 36. The sizes of the first locking sleeve 31 and the second locking sleeve 32 are adapted to each other. The locking cap 38 is threadedly connected to the outer wall of the locking screw 37 and is located outside one of the mounting blocks 35.

[0024] The sealing ring 11 squeezes the sealing gasket 23 and the sealing rubber ring 22 to make the two PE pipe ports fit together and align, which facilitates the initial sealing of the gap. At the same time, the first locking sleeve 31 and the second locking sleeve 32 are adapted to the size of the PE pipe and fit together to fit the gap. Finally, the locking cap 38 is used to limit and fix the locking screw 37, thereby locking the two mounting blocks 35 and improving the splicing tightness of the PE pipe.

[0025] like Figure 4 As shown, the innermost layer of the first PE pipe 1 and the second PE pipe 2 is made of food-grade high-density polyethylene layer 4, and the middle layer is made of glass fiber reinforced polyethylene mesh 5. The outermost layer of the first PE pipe 1 and the second PE pipe 2 is made of aging-resistant polyethylene layer 6. The inner and outer walls of the glass fiber reinforced polyethylene mesh 5 are covered with hot melt adhesive and are tightly bonded to the inner and outer layers.

[0026] By using a scientifically proportioned mixture of carbon black, antioxidants, and light stabilizers in the outer aging-resistant polyethylene layer 6, the pipe's resistance to ultraviolet aging and heat aging is significantly improved, as verified by accelerated aging tests. Then, a glass fiber reinforced polyethylene mesh 5 is used in the middle reinforcing layer, tightly bonded to the inner and outer layers with hot melt adhesive. The glass fiber and polyethylene matrix have a good bond, significantly improving the overall mechanical strength, impact resistance, and creep resistance of the pipe, making it less prone to damage under high-pressure water transport or complex geological environments. The inner layer is a food-grade high-density polyethylene layer 4, possessing excellent hygiene properties and chemical corrosion resistance, ensuring the safety of the transported water and preventing water pollution. This technology is relatively widely used.

[0027] The working principle and process of this utility model are as follows: When splicing and installing two PE pipes, the operator first inserts the sealing protrusion 11 of one end of the first PE pipe 1 into the sealing groove 21 inside the second PE pipe 2, so that the sealing protrusion 11 squeezes the sealing gasket 23 and sealing rubber ring 22 in the sealing groove 21, which facilitates the initial sealing of the two PE pipes. Then, the operator rotates the second locking sleeve 32 outside the limiting rod 33 on the first locking sleeve 31, and then puts the first locking sleeve 31 and the second locking sleeve 32 on the splice gap of the two PE pipes, so that the sealing sleeve 34 on the inner wall of the two locking sleeves further seals the gap. Then, the anti-slip knob 36 drives the locking screw 37 to be inserted into the two mounting blocks 35. Finally, the locking cap 38 is used to limit and fix it, which facilitates the relative sealing of the two PE pipes during splicing and installation, improves the sealing effect and avoids leakage.
