Abstract
The utility model discloses a prefabricated overhead insulating pipe, and relates to a device capable of reducing the heat loss of a heat medium pipeline. The prefabricated overhead insulating pipe comprises a core pipe, an insulating layer and a sleeve orderly sleeved on the outside of the core pipe, and end seals which are arranged at two longitudinal ends of the insulating layer. The prefabricated overhead insulating pipe comprises the core pip, and a thermal-protective layer, the insulating layer and the sleeve which are orderly sleeved on the outside of the core pipe, and the end seals which are arranged at two longitudinal ends of the insulating layer. A reflecting layer is arranged between the insulating layer and the thermal-protective layer, and a foam plastic is arranged in the insulating layer. Foaming layer end seals at two sides of the insulating layer of the prefabricated overhead insulating pipe provided by the utility model has a waterproof function; and therefore, the dry state in the insulating layer can be guaranteed, and the heat and cold loss of the insulating pipe is greatly reduced.
Description
Technical field
The utility model relates to a kind of device of carrying the hot medium pipeline thermal loss that reduces, and is applicable to carry vapour in the specific range of temperatures, water, oil or other without aggressive medium, particularly a kind of prefabricated built on stilts thermal insulation pipe.
Background technique
Heat supply, cooling pipeline produce heat or loss of refrigeration capacity when bearing transmission ﹠ distribution medium task and surrounding environment generation heat exchange.For reducing the energy loss of medium in circulation, to be incubated defeated heat and defeated cold pipeline, suppress the energy interchange of medium and environment.Traditional heat preserving mode is coated thermal insulating material outside the pipeline of fed sheet of a media, the built on stilts pipeline that lays, and the insulation operation is finished in the building site, and thermal insulating material communicates with atmosphere, and thermal insulating material makes moist easily, soaks and is subject to mechanical deterioration; Lagging casing has a large amount of slits, so heat preservation sandwich layer communicates with the external world, because Action of Wind pressure, and the inside and outside obvious temperature fall of shell, cold wind permeates in thermal insulation layer.Rainwater also can enter heat preservation sandwich layer by the slit, and thermal insulating material makes moist, and immersion is unavoidable.Steam line, its thermal insulation layer is immersion in a single day, and not only thermal insulation property degenerates, and may cause series of problems, and severe patient causes heat-insulation system to be scrapped.
The model utility content
The purpose of this utility model is to provide a kind of heat of thermal insulation pipe, prefabricated built on stilts thermal insulation pipe of refrigerating loss of reducing.
For solving the problems of the technologies described above, the prefabricated built on stilts thermal insulation pipe of the utility model comprises: core pipe and the thermal insulation layer and the sleeve pipe that are set in successively the described core pipe outside; And the end envelope, described end envelope is arranged on longitudinally two ends of described thermal insulation layer.In described thermal insulation layer, also be provided with foamed plastics.
Preferred prefabricated built on stilts thermal insulation pipe comprises: core pipe and the thermal-protective coating, thermal insulation layer and the sleeve pipe that are set in successively the described core pipe outside; The end envelope, described end envelope is arranged on longitudinally two ends of described thermal insulation layer.Between described thermal insulation layer and described thermal-protective coating, be provided with the reflecting layer.In described thermal insulation layer, also be provided with foamed plastics.
The end envelope of the thermal insulation layer both sides of the prefabricated built on stilts thermal insulation pipe of the utility model has water-proof function, when the heat supply network construction and installation, does not remove the end envelope, it is hereby ensured in the thermal insulation layer to keep dry state.Thereby guarantee that thermal insulation property does not reduce because of the thermal insulating material suction.The core pipe can be free to slide at the thermal insulation layer inner chamber.There is not heat bridge fully in this structure, and the built on stilts thermal insulation pipe support of tradition forms heat bridge, causes serious energy loss.The prefabricated built on stilts thermal insulation pipe of the utility model is a kind of Totally enclosed heat-preserving pipe, guarantees that thermal insulating material is in confined space.Simultaneously, filling foamed plastics in the thermal insulation layer is not so that there is air layer in whole thermal insulation layer.Can greatly reduce like this heat, the refrigerating loss of thermal insulation pipe.And the heat supply network that is connected into by the utility model thermal insulation pipe, every pipeline be prefabricated finishing in factory all, uses foam process that whole pipeline is formed an integral body.External protection sealing, waterproof.Therefore insulation, cold insulation effect are far beyond the site construction operation reliably.
