Description

Technical Field

[0001] The utility model relates to the technical field of heating pipes, in particular to a connecting structure for heating pipes. Background Art

[0002] At present, most of the industrial and domestic heating pipes used in urban centralized heating projects and large and medium-sized enterprises are buried directly underground, that is, the so-called direct buried heating pipes. When traditional equipment is used, the existing HVAC pipe construction generally adopts pipe welding or knob connection in sequence. However, due to the high construction intensity and the different levels of manual welding, it is easy to cause unqualified welding seals. At the same time, traditional threaded connections are often prone to insufficient sealing and leakage. When the pipe is used for a long time, it is easy to cause the sealing performance of the pipe to be damaged. In daily maintenance work, the traditional pipe welding structure or threaded connection method has a large workload when disassembling, resulting in low work efficiency of workers and is not conducive to use.

[0003] The patent with application number CN202321016060.3 discloses a HVAC pipe connection structure, including a fixed ring, the outer edge of the fixed ring is fixedly equipped with a connecting tube, the outer edge of the fixed ring is fixedly equipped with a main screw, the outer edge of the main screw is threadedly connected to the main wire ring, the outer wall of the main wire ring is fixedly equipped with a U-shaped ring, the inner cavity of the U-shaped ring is fixedly equipped with an adjustment ring, the inner cavity of the U-shaped ring is fixedly equipped with a secondary wire ring, the inner wall of the secondary wire ring is threadedly connected to the secondary wire, and the outer edge of the secondary wire is fixedly equipped with a clamping ring. The HVAC pipe connection structure, through the clamping ring and the main and secondary screws set on the outer wall of the main pipe, through the angle between the clamping ring and the main pipe, when the main pipe needs to be connected, it only needs to clamp the clamping ring to the outer wall of the main pipe, and then tighten the fixing screw at the bottom, and the clamping ring can be clamped to the outer wall of the main pipe by shortening the distance between the main screw and the secondary screw.

[0004] However, the existing heating pipeline connection is a rigid connection. When the pipeline is vibrated, it will be damaged and difficult to recover automatically. Therefore, it is necessary to improve the design of its connection to prevent permanent damage to the heating pipeline caused by earthquakes. Utility Model Content
