[0028] 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.

[0029] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a hot water delivery pipe for an air-to-water hot water project, comprising a delivery pipe 1 and a delivery pipe 2, a card slot 3 is provided inside the delivery pipe 1, the card slot 3 is used to provide a locking fitting part, the delivery pipe 1 is slidably connected to the inside of the delivery pipe 2, so that the two pipes can be tightly combined and maintain good connection stability, a locking assembly is provided on the outer wall of the delivery pipe 2, the locking assembly is used to effectively fix the delivery pipe 1 to avoid loosening during use, a cavity 4 is provided inside the delivery pipe 2, the cavity 4 is used to accommodate the movable parts in the locking assembly, a reset assembly is provided on the outer wall of the delivery pipe 2, the reset assembly is used to realize the automatic reset function, thereby ensuring the smooth progress of the locking process, a sealing assembly is provided inside the delivery pipe 2, the sealing assembly is used to provide a sealing function to prevent water leakage at the pipe connection;

[0030] The locking assembly includes a ball 5, which is slidably connected to the interior of the cavity 4. The ball 5 is used to engage with the card slot 3 to form a stable locking structure, ensuring that the connection between the delivery pipe 1 and the delivery pipe 2 is firm and reliable. The outer wall of the delivery pipe 2 is slidably connected to a release sleeve 6, which is used to drive the ball 5 to move, thereby facilitating the installation and removal of the pipeline. The release sleeve 6 is fixedly connected to the interior of the release sleeve 6. The convex ring 7 is used to limit the range of movement of the ball 5, ensuring the precise and reliable operation of the locking assembly. The reset assembly includes a spring 8, which is mounted on the outer wall of the delivery pipe 2. The spring 8 is used to provide an elastic reset force to ensure that the release sleeve 6 can quickly return to its initial position after the operation is completed. One end of the spring 8 is fixedly connected to the interior of the delivery pipe 2, and the other end is fixedly connected to one side of the convex ring 7. This structural design effectively avoids the problem of incomplete locking due to component offset or external force. The sealing assembly includes a sealing ring 9, the outer wall of which is fixedly connected to the inside of the delivery pipe 2. The sealing ring 9 is used to fill the gap between the delivery pipe 1 and the delivery pipe 2. The inner wall of the sealing ring 9 fits tightly against the outer wall of the delivery pipe 1, achieving a leak-proof effect and ensuring that the delivery pipe can still maintain good sealing performance under high pressure or high temperature conditions.

[0031] Specifically, during the connection process between delivery tube 1 and delivery tube 2, the release sleeve 6 is first manually operated, pushing it toward delivery tube 2. This action drives the protruding ring 7 forward, releasing the contact between the protruding ring 7 and the ball 5, thereby allowing the ball 5 to move within the cavity 4. At the same time, the position-limiting design of the cavity 4 ensures that the ball 5 remains within the defined range and does not fall out. Subsequently, delivery tube 1 is aligned with the inner cavity of delivery tube 2 and slowly inserted, ensuring that the axes of the two are aligned. When the release sleeve 6 is released, the tension of the spring 8 quickly acts on the protruding ring 7, causing it to return to its initial position and press against the ball 5. At this point, the ball 5, pushed by the protruding ring 7, engages the retaining groove 3 within delivery tube 2, securely locking delivery tube 1. A sealing ring 9 provided at the connection point ensures a precise seal between the two delivery tubes, preventing liquid or gas leakage and enhancing the stability of the connection. This design simplifies the operational process while ensuring a secure and reliable connection between delivery tubes 1 and 2, enhancing the practicality and ease of operation of the overall device.

[0032] Reference Figure 3 A conveying layer 10 is provided inside the conveying pipe 1. The conveying layer 10 is used to carry and convey hot water. It has high heat resistance and corrosion resistance, ensuring the stability and safety of hot water transportation. The outer wall of the conveying layer 10 is fixedly connected to an insulation layer 11. The insulation layer 11 is used to isolate heat loss. Its material has low thermal conductivity and excellent thermal insulation performance, which can significantly reduce heat loss during transportation and improve energy utilization efficiency. The outer wall of the conveying layer 10 is fixedly connected to the insulation layer 11. The double insulation design further enhances the stability of the insulation effect during hot water transportation. The outer wall of the insulation layer 11 is fixedly connected to a protective layer 12. The protective layer 12 is used to protect the pipeline from the influence of the external environment. Its material has the characteristics of wear resistance, corrosion resistance and heat reflection, thereby enhancing the service life and safety of the entire pipeline. The conveying pipe 1 is composed of a conveying layer 10, an insulation layer 11 and a protective layer 12. This multi-layer structure design realizes the organic combination of transportation, insulation and protection functions, and has high structural strength and functional integration. The insulation layer 11 is fixedly connected to the interior of the insulation layer 11 with reinforcing ribs 13. The reinforcing ribs 13 are arranged in a circular array and fixedly connected to the interior of the insulation layer 11. The provision of the reinforcing ribs 13 can effectively enhance the mechanical strength of the insulation layer 11, improve the tensile and compressive resistance of the delivery pipe 1, and prevent the pipe from being deformed or damaged due to external forces during use.

[0033] Specifically, the structure of the delivery pipe 1 utilizes a multi-layered design, consisting of a delivery layer 10, an insulation layer 11, and a protective layer 12, to meet the stringent insulation and strength requirements of air-to-water heating systems. The delivery layer 10 is made of PPR polypropylene, a material that not only offers excellent heat resistance, enabling it to withstand the flow of high-temperature hot water for extended periods, but also possesses strong corrosion resistance, effectively extending the service life of the delivery pipe. The insulation layer 11 utilizes polyurethane foam, widely used in pipeline insulation due to its low thermal conductivity, significantly reducing heat loss and improving overall insulation effectiveness. Furthermore, the protective layer 12 utilizes an aluminum foil protective layer, whose primary function is to reflect heat, further enhancing the pipe's insulation capabilities. It also offers excellent fire resistance, improving the pipe's safety and reliability. To further enhance the pipe's mechanical strength, multiple reinforcing ribs 13 are cleverly designed within the insulation layer 11. These ribs significantly enhance the tensile strength of the delivery pipe 1 by optimizing its internal structure, enabling it to better withstand external tension and pressure in actual use. Through this structural design, we can achieve a significant improvement in the thermal insulation performance of the pipeline while also taking into account its strength requirements, providing a strong guarantee for the efficient and safe operation of hot water transportation.

[0034] Working principle: When using the hot water delivery pipe of the air-energy water heating project, first connect the delivery pipe 1 and the delivery pipe 2, then drive the release sleeve 6 to move the convex ring 7 toward the delivery pipe 2, so that the convex ring 7 is separated from the ball 5, so that the ball 5 has room to move inside the cavity 4 without falling, and then insert the delivery pipe 1 into the delivery pipe 2. After loosening the release sleeve 6, the convex ring 7 is driven by the tension of the spring 8 to return to the position against the ball 5, so that the ball 5 is embedded in the card slot 3 to lock the delivery pipe 1. The delivery pipe 1 and the delivery pipe 2 are sealed by the sealing ring 9, which is convenient for The effect of connecting the delivery pipe 1 and the delivery pipe 2 2 is that the delivery pipe 1 is composed of a delivery layer 10, an insulation layer 11 and a protective layer 12. The delivery layer 10 is made of PPR polypropylene and has good heat resistance and corrosion resistance. The insulation layer 11 is made of polyurethane foam material with low thermal conductivity and good thermal insulation performance. The protective layer 12 is an aluminum foil protective layer for reflecting heat, enhancing the thermal insulation effect, and improving fire resistance. At the same time, multiple reinforcing ribs 13 arranged inside the insulation layer 11 are used to improve the tensile strength of the delivery pipe 1, thereby achieving the effect of improving the thermal insulation of the hot water pipe while improving the strength.
