Description

Technical Field

[0002] The urban heating network refers to the pipeline network system used to supply heat energy to various buildings and facilities in the city. These pipes are usually used to transport hot water or steam to provide winter heating, hot water and other services. In the development of the urban heating network, transformation and capacity expansion have always been a crucial link.

[0003] After searching, a Chinese patent with announcement number CN213901220U discloses an energy-saving and pollution-reducing heating pipeline network. Most of the pipelines used in heating pipeline networks on the market do not have the function of energy saving and pollution reduction, which will cause a large waste of resources and may also allow harmful gases to enter the atmosphere, causing air pollution. The practicality is poor, and the pipelines on the network pipe cannot be quickly supported and fixed, and cannot be quickly changed according to different situations, which affects the use effect. By setting a first isolation sleeve, a second isolation sleeve, an insulation board, an air sucker and an induction controller, the gas leaked from the connection of the device can be isolated by setting the first isolation sleeve and the second isolation sleeve, thereby preventing the gas from entering the atmosphere and reducing pollution. In addition, through the induction controller, after sensing the leakage, the gas can be allowed to enter the pipeline again through the air sucker, and in conjunction with the insulation board, the loss can be effectively reduced and more energy-saving can be achieved.

[0004] During the renovation and capacity expansion of the heating network, new heating pipelines need to be connected. When the heating network is renovated and expanded, the pipelines are often connected by bolts and flanges, which is cumbersome and requires a lot of time and manpower. Utility Model Content
