They affect all aspects of people's lives, especially geothermal energy, which requires more environmental protection and energy conservation. When geothermal energy is reused, the pipelines used in the heating network need to be energy-saving, environmentally friendly, and clean. The metal pipes used in the past have many problems in terms of energy conservation and cleanliness, and the construction is also complicated. In terms of energy-saving insulation, the construction is complicated and it is easy to be damaged and corroded, which shortens the service life, increases the operating cost, and brings inconvenience to maintenance. Therefore, aerogel hollow insulation high-pressure plastic pipes are proposed. Summary of the Invention

It has many problems in energy saving and cleanliness, and is also complicated in construction. In terms of energy saving, thermal insulation and heat insulation, the construction is complicated and it is easy to be damaged and corroded, resulting in a shortened service life, increased operating costs, and inconvenience for maintenance.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] Aerogel hollow heat-insulating high-pressure plastic pipe includes a high-pressure heat-resistant pipe. The outer wall of the high-pressure heat-resistant pipe is provided with an aerogel felt strip or tape winding layer. The outer wall of the aerogel felt strip or tape winding layer is provided with an inner protective layer. The outer wall of the inner protective layer is provided with a first connecting layer. A fastening mesh is fixedly connected inside the first connecting layer.

[0006] Preferably, the high-pressure heat-resistant pipe is made of polyethylene plastic, and the inner protective layer is made of plastic.

[0007] Preferably, the first connecting layer is made of glass wool, and the fastening mesh is made of steel.

[0008] Preferably, a V-shaped strip is fixedly connected to the outer wall of the first connecting layer, and a second protective layer is fixedly connected to one end of the V-shaped strip.

[0009] Preferably, the second protective layer is made of plastic, and an outer protective layer is fixedly connected to the outer wall of the second protective layer. The outer protective layer is made of rubber sponge.

[0010] Preferably, the V-shaped bar annular array is located on the outer wall of the first connecting layer.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, by setting an aerogel felt strip or tape wrapping layer between the high-pressure heat-resistant pipe and the inner protective layer, the heat transfer and loss can be greatly reduced. It is thin and lightweight and has a significant heat insulation effect, which makes the pipe design and installation more convenient. It also has good fire resistance, which can prevent the spread of fire to a certain extent.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1 - Figure 3An embodiment of this utility model is provided: an aerogel hollow heat-insulating high-pressure plastic pipe, including a high-pressure heat-resistant pipe 1, an aerogel felt strip and tape winding layer 2 on the outer wall of the high-pressure heat-resistant pipe 1, an inner protective layer 3 on the outer wall of the aerogel felt strip and tape winding layer 2, a first connecting layer 4 on the outer wall of the inner protective layer 3, and a fastening mesh 5 fixedly connected inside the first connecting layer 4.

[0021] Specifically, the aerogel felt strip / tape wrapping layer 2 has extremely low thermal conductivity, which can greatly reduce heat transfer and loss. It also has certain compressive strength and flexibility, and can maintain good insulation effect and structural stability under high pressure inside the high-pressure heat-resistant pipeline 1. Compared with traditional insulation materials, the aerogel felt strip / tape wrapping layer 2 is thin and lightweight with significant insulation effect, which makes pipeline design and installation more convenient without adding too much weight and volume. It also has good fire resistance, which can prevent the spread of fire to a certain extent, and can also effectively prevent the intrusion of water vapor, avoiding the insulation layer from getting damp and reducing its insulation performance.

[0022] Reference Figure 2 The high-pressure, high-temperature resistant pipe 1 is made of polyethylene plastic, and the inner protective layer 3 is made of plastic.

[0023] Specifically, the inner protective layer 3, made of plastic, has a certain degree of corrosion resistance and pressure resistance.

[0024] Reference Figure 2 The first connecting layer 4 is made of glass wool, and the fastening mesh 5 is made of steel;

[0025] Specifically, the steel fastening mesh 5 can provide additional support and restraint to prevent the first connecting layer 4 from being over-compressed or displaced under pressure. When the pipeline is subjected to external pressure or impact, the fastening mesh 5 can disperse and bear some of the pressure, reducing the direct pressure on the first connecting layer 4, thereby protecting the structural integrity of the first connecting layer 4.

[0026] Reference Figure 2 A V-shaped strip 6 is fixedly connected to the outer wall of the first connecting layer 4, and a second protective layer 7 is fixedly connected to one end of the V-shaped strip 6;

[0027] Specifically, a partially hollow structure is formed between the second protective layer 7, the V-shaped strip 6, and the first connecting layer 4.

[0028] Reference Figure 2 The second protective layer 7 is made of plastic, and an outer protective layer 8 is fixedly connected to the outer wall of the second protective layer 7. The outer protective layer 8 is made of rubber sponge.

[0029] Specifically, the outer protective layer 8 made of rubber sponge material can further reduce heat exchange between the pipeline and the external environment, ensure the temperature stability of the medium inside the pipe, resist external mechanical damage, and the outer protective layer 8 made of rubber sponge material has good waterproof performance, which can prevent moisture from penetrating into the insulation layer and interior of the pipeline, and prevent pipeline corrosion and a decrease in insulation performance.

[0030] Reference Figure 2 The V-shaped strips 6 are arranged in a ring on the outer wall of the first connecting layer 4;

[0031] Specifically, a partially hollow structure is formed between the second protective layer 7, the V-shaped strip 6, and the first connecting layer 4. This hollow section forms an air insulation layer, further reducing heat transfer and enhancing the pipe's insulation performance. The V-shaped design of the V-shaped strip 6 ensures that a certain buffer space is provided when the internal pressure of the pipe changes suddenly, reducing the impact on the pipe wall.

[0032] Working principle: By setting an aerogel felt strip / tape wrapping layer 2 between the high-pressure heat-resistant pipe 1 and the inner protective layer 3, heat transfer and loss can be greatly reduced. It is thin and lightweight with significant insulation effect, which makes the pipe design and installation more convenient. It also has good fire resistance and can prevent the spread of fire to a certain extent. It can also effectively prevent the intrusion of water vapor and avoid the insulation layer from getting damp and reducing its insulation performance.
