Embodiment Construction
[0022] The specific implementation will be further described below in conjunction with the accompanying drawings:
[0023] figure 1 It is an axonometric schematic diagram of a cooling / heating flow medium pipeline with an air cavity with separate air cavities in sections. It is characterized in that the pipeline is composed of a working core tube 1, an outer tube 2, a connecting bracket 3 connecting the working core tube 1 and the outer tube 2, and an air cavity 4 between the working core tube 1 and the outer tube 2. The air cavity 4 described above is independently arranged in sections along the flow direction of the cold / hot fluid. The air cavity and the air cavity are not connected to each other.
[0024] figure 2 It is an axonometric schematic diagram of air chambers arranged in series in cooling / heating fluid pipelines with air chambers. It is characterized in that the pipeline is composed of a working core tube 1, an outer tube 2, a connecting bracket 3 connecting th...

The invention relates to a special pipeline for conveying hot / cold flow medium, in particular to a hot / cold flow medium supplying pipeline with air cavity. The invention is characterized in that the pipeline is composed of a working core pipe (1), an external pipe (2), a connecting bracket (3) and an air cavity (4) between the working core pipe (1) and the external pipe (2); the air cavity (4) is arranged section by section independently along the flowing direction of hot / cold flow medium or connecting the sections in series; the working core pipe (1) is used for conveying hot / cold flow medium for providing hot / cold flow energy; the external pipe (2) is used for protecting the working core pipe (1) and forming the air cavity (4) with the core pipe (1); and no matter whether the air cavity (4) is arranged section by section independently or connected in series, the air cavity (4) is an energy nodal point; therefore, the hot / cold flow medium supplying pipeline with air cavity is suitable for outdoor hot / cold supplying pipe network directly buried underground or arranged overhead, as well as heating cold supplying pipe network installed folded or unfolded indoors. The invention has good heat preservation performance and energy saving effect.
Description
technical field [0001] The invention relates to a special pipeline for transmitting cold / hot fluid, in particular to a cooling / hot fluid pipeline with an air cavity. Background of the invention [0002] At present, the outdoor pipe network of the central heating and cooling system has adopted a large number of heat supply pipes with polyurethane insulation layer or conforming to the insulation layer, such as "full plastic prefabricated direct buried insulation pipe" with application number 90214231.3 and " Heating pipes with composite insulation". They are directly buried in the ground, and have the characteristics of low cost, convenient installation, short construction period, small maintenance, and small heat loss. However, for high-temperature steam with a temperature exceeding 150°C, the polyurethane insulation layer will be carbonized, thereby destroying the structure of the polyurethane and shortening its service life and thermal insulation performance. The latter, ...
