Abstract
The utility model discloses a heat supply pipe, which comprises an outer pipe wall and an inner pipe wall and belongs to the field of heat supply pipelines. The heat supply pipe is characterized in that an inner pipe is located inside an outer pipeline, sections of the inner pipeline and the outer pipeline are concentric, the outer pipe wall consists of an outer pipe outer casing, an outer pipe inner casing and a heat insulation layer sandwiched between centers of the two casings, and the inner pipe wall consists of an inner pipe outer casing, an inner pipe inner casing and a heat insulation layer sandwiched between centers of the two casings. During usage, the inner pipeline is used for supplying water, and the outer pipeline is used for returning water. The heat supply pipe saves distribution space in terms of pipeline distribution. In terms of heat loss, heat of the water supplying pipe is dissipated to the water returning pipe, and portions of heat of the water returning pipe is lost externally, thereby greatly reducing heat loss and saving energy.
Description
(1) technical field
The utility model relates to the heat supply pipeline field, particularly a kind of heating tube of sleeve structure.
(2) background technique
At present the heat supply pipeline that adopts of China is buried underground undergroundly more, and water pipe separates with return pipe and is arranged in juxtaposition.This mode needs two pipe laying spaces; Article two, pipeline all contacts with extraneous, and thermal loss is bigger.
(3) summary of the invention
The purpose of this utility model is exactly in order to solve above technical problem, and a kind of new heat-supplying pipe is provided.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of heating tube comprises outer tube wall and inner pipe wall, adopts sleeve structure, and interior pipe is arranged in outer pipeline, pipe and outer tube concentric in the cross section.
Described outer tube wall is made of inside and outside two-layer housing and the thermal insulation layer that is clipped in the housing center.
Described inner pipe wall is made of inside and outside double Shell and the thermal insulation layer that is clipped in the housing center.
The utility model has been saved the laying space from layout of beam line, and to return pipe, return pipe externally has the part heat loss from water pipe heat dissipation on the heat dissipation, has significantly reduced thermal losses, energy saving like this.
(4) description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is cross section structure figure of the present utility model.
Wherein, 1, outer pipe shell; 2, thermal insulation layer; 3, outer tube inner casing; 4, outer pipeline; 5, interior pipeline; 6, interior pipe inner casing; 7, interior pipe shell; 8, thermal insulation layer.
(5) embodiment
Below in conjunction with embodiment the utility model is further described, but not as qualification of the present utility model:
Embodiment: a kind of heating tube, comprise outer tube wall and inner pipe wall, adopt sleeve structure, as depicted in figs. 1 and 2: pipe is arranged in outer pipeline 4 in described, pipe and outer tube concentric in the pipeline section.Described outer tube wall is made of outer pipe shell 1, outer tube inner casing 3 and the thermal insulation layer 2 that is clipped in the two housings center.Described inner pipe wall is made of interior pipe shell 7, interior pipe inner casing 6 and the thermal insulation layer 8 that is clipped in the two housings center.
During use, interior pipeline 5 is responsible for water supply, and outer pipeline 4 is responsible for backwater.
Above embodiment, the utility model specific embodiment a kind of preferably just, common variation and replacement that those skilled in the art carry out in the technical solutions of the utility model scope are included in the protection domain of the present utility model.
Claims (3)
1. a heating tube comprises outer tube wall and inner pipe wall, adopts sleeve structure, and interior pipe is arranged in outer pipeline (4); It is characterized in that: pipeline (5) and outer pipeline (4) cross section concentric in described.
2. a kind of heating tube according to claim 1 is characterized in that described outer tube wall is made of outer pipe shell (1), outer tube inner casing (3) and the thermal insulation layer (2) that is clipped in the two housings center.
3. a kind of heating tube according to claim 1 is characterized in that described inner pipe wall is made of interior pipe shell (7), interior pipe inner casing (6) and the thermal insulation layer (8) that is clipped in the two housings center.
