Description

Technical Field

[0001] This utility model relates to the technical field of water pipes, and in particular to a freeze-resistant water supply pipe. Background Technology

[0002] Water supply pipes are a crucial component of urban water supply systems, agricultural irrigation systems, and industrial water systems, and their performance directly affects the safety and reliability of the water supply system. In cold regions or low-temperature winter environments, water supply pipes often face the risk of freezing and cracking. When the water inside the pipe freezes, the volume expansion generates enormous pressure, causing the pipe to rupture, leading to problems such as water supply interruptions, water waste, and increased maintenance costs. Therefore, the research and development of freeze-resistant water supply pipes has significant practical implications.

[0003] In recent years, with the development of materials science and pipeline technology, some new types of antifreeze water supply pipes have emerged, such as those that improve antifreeze performance by adding an antifreeze coating to the inner wall or using a multi-layer composite structure. However, these improvements have two drawbacks: first, the antifreeze coating lacks durability and is prone to peeling off after long-term use; second, the manufacturing cost of the multi-layer composite structure is high, making it difficult to promote on a large scale. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a freeze-proof water supply pipe with long service life, strong adaptability and low cost.

[0005] This utility model provides an antifreeze and crack-resistant water supply pipe, comprising:

[0006] The inner lining is made of low-temperature resistant material to prevent the inside of the water pipe from freezing. The inner wall of the inner lining is smooth, and the outer wall of the inner lining is provided with spiral reinforcing ribs to enhance the pressure resistance of the pipe.

[0007] The insulation layer, located on the outer wall of the inner lining, is made of foamed polyethylene material to reduce heat loss.

[0008] The outer protective layer, located on the outer wall of the insulation layer, is made of UV-resistant and weather-resistant materials to protect the water pipes from external environmental corrosion.

[0009] Furthermore, the thickness of the inner lining layer is 1-3 mm:

[0010] The thickness of the insulation layer is 5-10mm:

[0011] The thickness of the outer protective layer is 2-5mm.

[0012] Preferably, the inner surface of the lining layer is provided with a spiral guide groove to enhance water flow and prevent water from stagnating and freezing inside the pipe.

[0013] Furthermore, an electric heating wire is installed inside the insulation layer. The electric heating wire is connected to an external temperature control device for automatic heating in low-temperature environments to prevent the water pipes from freezing.

[0014] Preferably, the electric heating wires are evenly distributed in the insulation layer, and the power of the electric heating wires is adjustable to adapt to different ambient temperatures.

[0015] Furthermore, the outer surface of the outer protective layer is provided with a reflective coating, which is used to reflect sunlight and reduce the impact of external heat on the water pipe.

[0016] Preferably, the outer surface of the outer protective layer is provided with anti-slip texture to increase the grip friction of the tube body, making it easier to install and disassemble.

[0017] Furthermore, the outer surface of the outer protective layer is marked with graduation lines along its length to facilitate precise cutting and installation during construction.

[0018] This design incorporates a freeze-resistant water pipe with an inner lining made of low-temperature resistant material. This effectively prevents ice formation inside the pipe, avoiding pipe rupture due to ice expansion and ensuring stable operation of the water supply system. The smooth inner wall significantly reduces water flow resistance, improves water delivery efficiency, and reduces energy consumption. The spiral reinforcing ribs on the outer wall greatly enhance the pipe's pressure resistance, allowing it to withstand greater external pressure and extending its service life. An insulation layer on the outer wall of the inner lining, made of foamed polyethylene, minimizes heat loss and maintains the water temperature inside the pipe, further reducing the risk of freezing. The outermost protective layer uses UV-resistant and weather-resistant materials to effectively resist damage from direct sunlight, wind, rain, and other external environmental factors, protecting the internal structure and ensuring long-term stable operation even in harsh environments. This comprehensive design enhances the freeze-resistant performance and overall durability of the water pipe, meeting the needs of diverse water supply scenarios. Attached Figure Description

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] This utility model relates to an antifreeze and crack-resistant water supply pipe, such as... Figures 1 to 4 As shown, it includes:

[0026] The inner lining 1 is made of low-temperature resistant materials, such as high-density polyethylene, to prevent the inside of the water pipe from freezing. The inner wall of the inner lining 1 is smooth, and the outer wall of the inner lining 1 is provided with spiral reinforcing ribs 2 to enhance the pressure resistance of the pipe.

[0027] Insulation layer 3 is set on the outer wall of inner lining layer 1. Insulation layer 3 is made of foamed polyethylene material to reduce heat loss.

[0028] The outer protective layer 4 is set on the outer wall of the insulation layer 3 and is made of UV-resistant and weather-resistant materials, such as polyvinyl chloride, to protect the water pipe from external environmental corrosion.

[0029] The inner lining layer 1, made of low-temperature resistant materials, effectively prevents ice formation inside the water pipe from the source, avoiding pipe rupture due to ice expansion and ensuring stable operation of the water supply system. Its smooth inner wall greatly reduces water flow resistance, improves water delivery efficiency, and reduces energy consumption. The spiral reinforcing ribs 2 on the outer wall significantly enhance the pipe's pressure resistance, enabling the water pipe to withstand greater external pressure and extend its service life. The insulation layer 3, located on the outer wall of the inner lining layer, is made of foamed polyethylene material. With its excellent thermal insulation properties, it minimizes heat loss, maintains the water temperature inside the pipe, and further reduces the risk of freezing. The outermost protective layer 4 is made of UV-resistant and weather-resistant material, which can effectively resist damage to the water pipe from external environmental factors such as direct sunlight and wind and rain erosion, protect the internal structure, and ensure that the water pipe can still work stably for a long time in harsh environments. It comprehensively improves the anti-freezing and cracking performance and overall durability of the water supply pipe, meeting the needs of diverse water supply scenarios.

[0030] As a preferred option, such as Figures 1 to 3 As shown, the thickness of the inner lining layer 1 is 1-3 mm:

[0031] The thickness of insulation layer 3 is 5-10mm:

[0032] The outer protective layer 4 has a thickness of 2-5 mm;

[0033] The inner lining layer 1 is designed with a thickness of 1-3mm, which ensures that the low-temperature resistant material effectively prevents the water pipe from freezing inside and avoids ice expansion and cracking, while not being too thick and affecting the water flow space. At the same time, it maintains the smoothness of the inner wall to reduce water flow resistance, and allows the spiral reinforcing ribs 2 on the outer wall to fully play their role in enhancing the pressure resistance. It achieves efficient water delivery while ensuring the stable operation of the water supply system. The insulation layer 3 is 5-10mm thick. It can utilize the good heat insulation properties of foamed polyethylene to just right reduce heat loss, maintain the water temperature inside the pipe, and further reduce the risk of freezing. It provides strong protection against freezing without increasing costs or pipe diameter too much. The outer protective layer 4 is 2-5mm thick and is made of materials with strong UV resistance and weather resistance, such as polyvinyl chloride. It can effectively resist damage to the water pipe from external environmental factors such as direct sunlight and wind and rain erosion, protect the internal structure, and ensure that the water pipe works stably for a long time in harsh environments. It ensures the protective effect while taking into account economy and practicality, comprehensively improving the anti-freezing and cracking performance and overall durability of the water supply pipe, and meeting the needs of diverse water supply scenarios.

[0034] As a preferred option, such as Figures 1 to 4 As shown, the inner surface of the inner lining layer 1 is provided with a spiral guide groove 5 to enhance water flow and prevent water from stagnating and freezing inside the pipe.

[0035] The spiral guide groove 5 set on the inner surface of the inner lining layer 1 can significantly enhance the flow of water. Its spiral structure guides the water flow to form a spiral forward trajectory, effectively preventing water from stagnating in the pipe and reducing the risk of water freezing due to stillness in low temperature environment.

[0036] As a preferred option, such as Figures 1 to 3 As shown, an electric heating wire 6 is installed inside the insulation layer 3. The electric heating wire 6 is connected to an external temperature control device for automatic heating in low-temperature environments to prevent water pipes from freezing.

[0037] The electric heating wire 6 embedded in the insulation layer 3 is connected to an external temperature control device, which greatly improves the antifreeze performance of the water supply pipe in low-temperature environments. When the ambient temperature drops to the set low-temperature threshold, the temperature control device automatically starts, and the electric heating wire 6 heats up quickly to replenish the heat of the insulation layer 3, effectively preventing the water temperature inside the pipe from continuing to drop, preventing the water from freezing into ice, and avoiding pipe rupture due to ice expansion. This ensures that the water supply system continues to operate stably under extremely cold conditions. This design not only enhances the water supply pipe's ability to cope with extreme low-temperature environments, but also improves the reliability and safety of the entire water supply system, providing a more stable and efficient guarantee for diverse water supply scenarios. Without increasing energy consumption and maintenance costs, it further improves the antifreeze and crack prevention function of the water supply pipe, meeting the water needs of different users under complex climatic conditions.

[0038] As a preferred option, such as Figures 1 to 3As shown, the electric heating wire 6 is evenly distributed in the insulation layer 3, and the power of the electric heating wire 6 is adjustable to adapt to different ambient temperatures.

[0039] The electric heating wire 6 is evenly distributed in the insulation layer 3, ensuring that heat can be evenly transferred throughout the insulation layer, avoiding local overheating or undercooling, and maintaining the water temperature in the water pipe within a suitable range. This comprehensively prevents the water pipe from freezing and ensures the stability of the water supply. Its adjustable power design is a major highlight. It can flexibly adjust the heating power to meet different ambient temperatures. In extremely cold weather, the power output can be increased to quickly raise the water temperature and resist the cold. When the temperature is relatively high, the power can be reduced to reduce unnecessary energy consumption. While ensuring efficient antifreeze, it also takes into account energy-saving needs, which not only improves the adaptability of the water supply pipe in complex climatic conditions, but also effectively controls operating costs.

[0040] As a preferred option, such as Figures 1 to 3 As shown, the outer surface of the outer protective layer 4 is provided with a reflective coating 7, which is used to reflect sunlight and reduce the impact of external heat on the water pipe.

[0041] The reflective coating 7 on the outer surface of the outer protective layer 4 can efficiently reflect sunlight, greatly reducing the heat from direct sunlight from being conducted into the water pipe. This effectively reduces the rise in water temperature inside the pipe under high-temperature conditions, preventing problems such as pipe deformation or internal water vaporization caused by excessively high water temperature. It maintains stable water temperature inside the pipe and further enhances the overall stability and durability of the water pipe in conjunction with other structures. Especially in hot and sunny environments, it can significantly improve the performance of the water supply pipe, reduce water supply failures caused by temperature factors, and provide more reliable protection for diverse water supply scenarios. It comprehensively meets the needs of efficient and stable operation of water supply pipes in different environments.

[0042] As a preferred option, such as Figures 1 to 3 As shown, the outer surface of the outer protective layer 4 is provided with anti-slip texture to increase the grip friction of the tube body, making it easy to install and disassemble;

[0043] The anti-slip texture on the outer surface of the outer protective layer 4 greatly improves the ease of installation and disassembly of water supply pipes. During installation, construction workers can use the extra gripping friction provided by the anti-slip texture to more steadily grasp and fix the pipe, accurately adjust the position of the water pipe, reduce the risk of slippage caused by the smooth surface of the pipe, effectively improve installation efficiency, and reduce installation difficulty.

[0044] As a preferred option, such as Figure 1 As shown, the outer surface of the outer protective layer 4 is marked with scale lines along its length to facilitate precise cutting and installation during construction;

[0045] During construction, workers can precisely cut water pipes according to the scale lines without the need for additional measuring tools, ensuring that the cut length meets the installation requirements, reducing material waste caused by measurement errors, and lowering construction costs. At the same time, the scale lines help workers to more accurately control the splicing position of each section of water pipe during installation, making the installation process more efficient and accurate, effectively improving the overall construction progress and quality, and meeting the needs of diverse water supply projects for water pipe installation accuracy and convenience.

[0046] The antifreeze and crack-resistant water supply pipe of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0047] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
