Description

Technical Field

[0001] The utility model relates to the technical field of heating pipeline auxiliary equipment, in particular to an antifreeze structure for an exhaust end of a long-distance heating pipeline. Background Art

[0002] Due to the long heating distance of long-distance pipelines, there will be gases in the pipelines, such as air and water vapor. These gases will affect the heating effect and the stable operation of the pipeline system. Therefore, in order to make the heating effect better and the system more stable, the indoor heating pipes need to be exhausted to the outdoors through exhaust pipes.

[0003] The exhaust end of the existing heating pipeline is prone to freezing when the water temperature drops at the beginning of heating and during heating, which will cause the exhaust end to be unable to vent normally and affect the normal use of the heating pipeline. For this reason, we propose an anti-freezing structure for the exhaust end of a long-distance heating pipeline. Utility Model Content
