Description

Technical Field

[0001] The utility model relates to the field of heating pipe networks, and in particular to a novel heating pipe network node anti-leakage device. Background Art

[0002] The thermal network starts from the boiler room, direct-fired machine room, heating center, etc., and the heating pipelines from the heat source to the thermal entrance of the building. Multiple heating pipelines form a network. Since the heating network generally uses direct-buried insulated pipes, when the area where the pipeline is buried is subjected to the heavy pressure of some heavy objects for a long time, the area of ​​the pipeline may sink, which will cause the metal of the pipe joint to break due to the pressure. For this reason, a Chinese patent with publication number CN211693994U has announced a leak-proof device for use in a heating network system. The device forms a certain distance between a limit ring and a clamping ring, and forms a clamping structure in the axial direction, so that the two sub-joints can form a certain displacement in the axial direction. After the displacement, the clamp, the clamping ring and the sub-joint form a relatively closed structure, thereby reducing water leakage at the sub-joint.

[0003] However, in actual use, especially when the land settlement of the buried road section is large, the displacement between the two sub-joints is greater than the range of the clamping ring, which will still cause fractures at the pipeline interface and subsequent leakage.
