Description

Technical Field

[0001] This utility model relates to the field of heating pipeline technology, specifically to an insulated heating pipeline for a gas-fired boiler. Background Technology

[0002] Gas-fired boilers, as a key component of heating equipment, generate heat energy by burning gas, which is then transported to users via a pipeline system. Heating pipelines are crucial structures used in conjunction with gas-fired boilers to achieve heat transfer. These pipelines require high thermal insulation performance to minimize heat loss during transmission. Existing thermal insulation methods for heating pipelines often involve wrapping the outer wall with insulating materials such as sponge, without any protective structures for these materials. Insulation materials are prone to damage during use, thus affecting the pipeline's insulation effectiveness. Therefore, we propose an insulated heating pipeline for gas-fired boilers. Utility Model Content

[0003] The purpose of this utility model is to provide an insulated heating pipe for a gas boiler to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an insulated heating pipe for a gas boiler, comprising an inner pipe, with connecting flanges fixedly connected to the front and rear ends of the inner pipe, an insulation component wrapped around the outer wall of the inner pipe, an outer pipe assembled on the outer wall of the inner pipe, and a fixing mechanism assembled between the inner pipe and the outer pipe.

[0005] Preferably, the insulation component includes a first glass wool layer, an aluminum foil reflective layer, a second glass wool layer, and a nano-airbag layer, which are arranged sequentially from the inside to the outside on the outer wall of the inner tube.

[0006] Preferably, the outer tube includes two tube bodies, which are symmetrically distributed about the central axis of the inner tube, and each of the two tube bodies has a support block fixedly connected to its opposite sidewall.

[0007] Preferably, the support blocks are evenly distributed in a circle around the central axis of the inner tube on the side wall of the tube body.

[0008] Preferably, the fixing mechanism includes a fixing block, which is fixedly connected to the side wall of the inner tube, and a connecting block is fixedly connected to the side wall of the outer tube. A fixing bolt and a fixing nut are fixedly assembled between the fixing block and the connecting block.

[0009] Preferably, there are two sets of fixing blocks, with the two sets of fixing blocks located at the front and rear ends of the inner tube, respectively. Each set of fixing blocks consists of two blocks, which are symmetrically distributed vertically. The position of the connecting block corresponds to the position of the fixing block.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: A heat-insulated heating pipe for a gas-fired boiler, compared to traditional heating pipes, firstly employs an insulation component composed of four layers of insulation material. This component not only insulates the heating pipe but also reflects heat energy inward, thereby improving the heat insulation effect. Simultaneously, an outer pipe is detachably fixed via a fixing mechanism. The outer pipe, positioned outside the inner pipe, effectively protects the insulation material. Support blocks are provided on the inner wall of the outer pipe. While protecting the insulation material, the outer pipe also helps maintain the fit between the insulation material and the inner pipe, further enhancing the insulation performance during use.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a technical solution: a heat-insulated heating pipe for a gas boiler, including an inner pipe 1. Connecting flanges 2 are fixedly connected to the front and rear ends of the inner pipe 1, and the connecting flanges 2 are used for connecting and fixing the inner pipes 1. The outer wall of the inner pipe 1 is wrapped with a heat-insulating component 3, and an outer pipe 4 is assembled on the outer wall of the inner pipe 1. A fixing mechanism 5 is assembled between the inner pipe 1 and the outer pipe 4. The fixing mechanism 5 is used to detachably fix the outer pipe 4 to the outside of the inner pipe 1. The heat-insulating component 3 is wrapped around the outer wall of the inner pipe 1, mainly to provide heat insulation for the inner pipe 1. The outer pipe 4 can protect the heat-insulating component 3, improve the stability of the assembly and fixing between the heat-insulating component 3 and the inner pipe 1, extend the service life of the heat-insulating component 3, and avoid damage to some parts of the heat-insulating component 3, thereby affecting its heat insulation performance for the inner pipe 1.

[0020] like Figure 2 and Figure 3 As shown, the insulation component 3 includes a first glass wool layer 31, an aluminum foil reflective layer 32, a second glass wool layer 33, and a nano airbag layer 34. The first glass wool layer 31, the aluminum foil reflective layer 32, the second glass wool layer 33, and the nano airbag layer 34 are arranged sequentially from the inside to the outside. The insulation layer formed by the first glass wool layer 31 and the second glass wool layer 33 provides thermal insulation for the internal pipe 1. The aluminum foil reflective layer 32 and the nano airbag layer 34 can reflect outward heat radiation, and the hollow and sealed airbags of the nano airbag layer 34 further block heat conduction, thereby reducing heat loss from the pipe and improving the thermal insulation performance of the insulation component 3 for the internal pipe 1.

[0021] like Figure 1 , Figure 2 and Figure 6 As shown, the outer tube 4 includes a tube body 41, which are arranged opposite to each other. Support blocks 42 are evenly welded and fixed to the opposite side walls of the two tube bodies 41. The support blocks 42 are evenly distributed circumferentially along the inside of the tube body 41. After the tube body 41 is assembled and fixed to the outside of the inner tube 1, the support blocks 42 are in contact with the outer wall of the insulation component 3. By applying pressure to the insulation component 3 in the circumferential direction, the insulation component 3 is prevented from cracking outward during long-term use. This can effectively make the insulation component 3 fit with the outside of the inner tube 1.

[0022] like Figure 2 , Figure 4 and Figure 5As shown, the fixing mechanism 5 includes fixing blocks 51, which are integrally formed on the side wall of the inner tube 1. Two fixing blocks 51 are arranged in a group, and each group of fixing blocks 51 is symmetrically distributed from top to bottom. The two groups of fixing blocks 51 are located at the front and rear ends of the inner tube 1, respectively. The side wall of the outer tube 4 is integrally formed with connecting blocks 52 corresponding to the positions of the fixing blocks 51. Fixing bolts 53 and fixing nuts 54 are assembled between the connecting blocks 52 and the fixing blocks 51. By setting the fixing mechanism 5, the outer tube 4 and the inner tube 1 can be detachably fixedly connected. When the inner tube 1 is repaired and maintained or the insulation component 3 is replaced, it is convenient to disassemble the outer tube 4. Moreover, the outer tube 4 can be recycled, saving costs.
