Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe technology, and in particular to a composite thermal insulation pipe that can be quickly installed. Background Technology

[0002] Hydronic heating is one type of radiant floor heating and one of the most popular heating methods. It uses hot water at a temperature not exceeding 60℃ as the heat medium, which circulates within heating pipes to heat the floor. Heat is then transferred to the room through radiation and convection. Hydronic pipes are used in the installation of conduits in hydronic and electrical installation projects and are an auxiliary part of the project. The quality of their installation has a significant impact on the overall quality of the hydronic and electrical installation project. Hydronic pipe connection structures are used to connect the hydronic pipes to ensure the normal operation and safety of the hydronic system. Existing hydronic pipe connection structures usually connect and fix the hydronic pipes by welding or hot fusion, which usually requires professional operation and is relatively cumbersome. When the pipes are damaged, it is not easy to disassemble and replace them. Utility Model Content

[0003] The purpose of this invention is to provide a composite insulation pipe that can be installed quickly, so as to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A quick-installable composite insulation pipe includes a pipe with flanges at both ends. The flanges are integrally formed with the pipe. The flanges are discs with an outer diameter larger than the outer diameter of the pipe and an inner diameter consistent with the inner diameter of the pipe. Connecting devices are provided at both ends of the pipe. The connecting device includes a sleeve, a first ring, and a washer. Both ends of the sleeve are fully open, and the inner wall of the sleeve is threaded. A second ring is screwed to one end of the sleeve and fitted onto the pipe. The second ring is composed of two half-rings joined together and screwed into one end of the sleeve. Rings are fitted at both ends of the pipe, and the structure of the first ring is identical to that of the second ring.

[0005] By adopting the above technical solution, since the outer diameter of the flanges at both ends of the pipeline is larger than the outer diameter of the pipeline, it is necessary to adapt the inner diameter of the sleeve to the outer diameter of the flange. If the first ring and the second ring are made as a single piece, they cannot be fitted onto the pipeline. Therefore, they are designed as a structure composed of two half-rings spliced ​​together, which realizes the quick connection of the pipeline. Through the mutual cooperation of the flanges, the mating ends of the two pipelines are firmly locked together. The gasket is placed between the first ring, the second ring and the end of the flange away from the pipeline end, so that the gasket can distribute the force and facilitate the spiral locking of the first ring and the second ring, avoiding direct friction between the first ring and the flange surface when locking.

[0006] In a further embodiment, the end face of the first ring is provided with a plurality of blind holes along its axial direction.

[0007] By adopting the above technical solution, it is convenient to use a specific locking tool to lock the first ring inside the sleeve.

[0008] In a further embodiment, a limiting protrusion is provided inside one end of the sleeve where the second ring is mounted, the limiting protrusion being used to restrict the position of the second ring inside the sleeve.

[0009] In a further embodiment, the portion of the sleeve that fits against the outer wall of the flange is a smooth surface, and the diameter of the smooth surface transitions with the outer diameter of the flange. An annular groove is provided in the middle of the smooth surface, and a sealing ring is fixedly installed in the annular groove.

[0010] By adopting the above technical solution, the sealing ring blocks the mating surfaces of the two flanges, achieving a sealing effect at the connection between pipes.

[0011] In a further embodiment, a wire mesh frame is embedded inside the flange.

[0012] By adopting the above technical solution, the pipeline is injection molded. During the injection molding process, the wire mesh frame is placed inside the mold to achieve the embedded setting. The wire mesh frame is used to make the flange structural strength higher and better able to bear the force.

[0013] In a further embodiment, the end face of the flange is provided with a circular groove, and an O-ring is provided in the groove.

[0014] In summary, this utility model has the following beneficial effects: 1. Because the outer diameter of the flanges at both ends of the pipe is larger than the outer diameter of the pipe, the inner diameter of the sleeve needs to be matched with the outer diameter of the flange. If the first and second rings were made as a single piece, they would not fit onto the pipe. Therefore, they are designed as a structure composed of two half-rings spliced ​​together, which enables quick connection of the pipe. Through the mutual cooperation of the flanges, the mating ends of the two pipes are firmly locked together. The gasket is placed between the first and second rings and the end of the flange away from the pipe end. This allows the gasket to distribute the force and facilitates the screw locking of the first and second rings, avoiding the effect of the first and second rings directly rubbing against the surface of the flange when locking.

[0019] Example 1: like Figure 1As shown, a quick-installable composite insulation pipe includes a pipe 1, with flanges 2 at both ends of the pipe 1. The flanges 2 are integrally formed with the pipe 1. The flanges 2 are discs, with an outer diameter larger than the outer diameter of the pipe 1 and an inner diameter matching that of the pipe 1. Connecting devices 3 are provided at both ends of the pipe 1. The connecting device 3 includes a sleeve 31, a first ring 32, and a washer 33. Both ends of the sleeve 31 are fully open, and the inner wall of the sleeve 31 is threaded. A second ring is screwed to one end of the sleeve 31 and is fitted onto the pipe 1. The second ring is composed of two half-rings joined together. A ring is screwed into one end of the sleeve 31. Both ends of the pipe 1 are fitted with rings. The structure of the first ring 32 is the same as that of the second ring. Multiple blind holes are provided axially on the end face of the first ring 32. The part of the sleeve 31 that fits against the outer wall of the flange 2 is a smooth surface, and the diameter of the smooth surface transitions with the outer diameter of the flange 2. An annular groove is provided in the middle of the smooth surface, and a sealing ring is fixedly installed in the annular groove. A wire mesh frame is embedded inside the flange 2. A circular groove is provided on the end face of the flange 2, and an O-ring is provided in the groove. Specific implementation process: Because the outer diameter of the flanges at both ends of the pipeline is larger than the outer diameter of the pipeline, the inner diameter of the sleeve needs to be adapted to the outer diameter of the flange. If the first and second rings are made as a single piece, they cannot be fitted onto the pipeline. Therefore, they are designed as a structure composed of two half-rings spliced ​​together, which realizes the quick connection of the pipeline. Through the mutual cooperation of the flanges, the mating ends of the two pipelines are firmly locked together. The gasket is placed between the first and second rings and the end of the flange away from the pipeline end, so that the gasket can distribute the force and facilitate the screw locking of the first and second rings, avoiding direct friction between the first and second rings and the surface of the flange when locking.
