Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, and more specifically, to a directly buried prefabricated thermal insulation pipe. Background Art

[0002] Insulated pipe is a piping system used to transport fluids. The pipe is coated with an insulating material, typically polyurethane or glass wool, to reduce heat loss and maintain a stable temperature within the pipe. Insulated pipe is widely used in the industrial sector, particularly in the petrochemical industry, HVAC, and heating and cooling. It effectively reduces energy consumption and maintenance costs, while improving the efficiency and safety of piping systems. With excellent thermal insulation and durability, it can meet the requirements of diverse environments and fluid transport requirements, making it a crucial piece of pipeline protection.

[0003] Direct-buried prefabricated insulated pipe is a type of insulation used in underground piping systems. It typically consists of an inner pipe, insulation layer, and outer pipe, prefabricated in the factory before being installed on-site. The inner pipe is used to transport fluids, the insulation layer utilizes high-quality thermal insulation materials, and the outer pipe protects and supports the entire piping system. Direct-buried prefabricated insulated pipe features easy installation, excellent insulation performance, and corrosion resistance. It is widely used in urban heating, HVAC, industrial piping, and other fields, effectively reducing energy loss and maintenance costs while improving the efficiency and reliability of piping systems.

[0004] Existing direct-buried prefabricated insulated pipes may be damaged after long-term use, and most of them are connected by bolts, which makes it cumbersome to install and disassemble them, resulting in a cumbersome replacement and maintenance process; most of the existing insulated pipes lack buffer devices, which may cause damage to the insulated pipes when they are hit, affecting the service life of the insulated pipes. For this reason, we propose a direct-buried prefabricated insulated pipe. Utility Model Content

The outer wall of the insulation pipe 2 120 is symmetrically fixed with the limit block 160, which is used to limit the insulation pipe 2 120. Pull the push rod 140, and then insert the second insulation pipe 120 into the connecting sleeve 130. After loosening the push rod 140, the spring 1 pushes the limiting ring 141, driving the push rod 141 to move into the connecting sleeve 130, so that the fixing seat 150 is disengaged from the bayonet. The spring 2 pushes the push block 151 to limit the limiting block 160, fixing the second insulation pipe 120, and the second insulation pipe 120 can be quickly installed.

The second insulation pipe 120 can be quickly disassembled, which is convenient for replacing and repairing the insulation pipe.

[0027] The insulation pipe 100 includes an inner pipe 200, and a plurality of rubber plates 210 are symmetrically fixed on the outer wall of the inner pipe 200 to cushion the inner pipe 200. A shell 250 is fixed on the top of the rubber plate 210 to protect the inner pipe 200. A plurality of support seats 220 are fixed on the outer wall of the inner pipe 200 to support the support rod 230. The support rod 230 is embedded on the top of the support seat 220. The inner wall of the shell 250 is fixed with a plurality of support seats 220 that are mutually connected with the support rod 230. The matching support seat 240 is used to limit the support rod 230. When the insulation pipe is hit, the arc-shaped rubber plate 210 bends under the force to absorb the impact force, which can buffer the inner tube 200. At the same time, the support rod 230 moves inside the support seat 1 220 and the support seat 2 240, and its two ends are buffered by the buffer block 1 221 and the buffer block 2 241 at the same time. Combined with the arc-shaped rubber plate 210, the buffering effect on the inner tube 200 can be better.

A buffer block 241 is fixed inside the support seat 240 and cooperates with the support rod 230 for buffering the support rod 230. A reinforcing rod 260 is fixed between the multiple support rods 230 and the rubber plate 210 to make the installation of the support rod 230 and the rubber plate 210 more stable.

When the insulation tube is hit, the arc-shaped rubber plate 210 bends under the force to absorb the impact force, which can buffer the inner tube 200. At the same time, the support rod 230 moves inside the support seat 1 220 and the support seat 2 240, and its two ends are buffered by the buffer block 1 221 and the buffer block 2 241 at the same time. Combined with the arc-shaped rubber plate 210, the buffering effect on the inner tube 200 can be better.
