Abstract
The invention discloses an efficient heat-insulation pipeline. An inner pipe (1), a jacketed pipe (2), a carbon foaming base material heat-insulation layer (3) and a heat-insulation cotton layer (4) are sequentially arranged on the pipeline wall from inside to outside, the jacketed pipe (2) is sleeved on the outer side of the inner pipe (1), and an annular cavity (5) is arranged between the inner pipe (1) and the jacketed pipe (2). The annular cavity which can be used for heat transfer medium to flow is further arranged between the stainless steel pipes on the basis of adhering the two heat-insulation material layers to the outer sides of the stainless steel pipes, the heat insulation principle by the cavity is utilized, and the cavity can be used for heat supply. The efficient heat-insulation pipeline is concise in structure, good in heat insulation, lower in flow noise of fluid, seamless by integral forming, high in vibration resistance, long in service life and wide in application range.
Description
Technical field
The present invention relates to Fluid Transport equipment technical field, refer in particular to a kind of transmission pipeline that transmitting fluid is incubated of can be used for, specifically a kind of high-efficiency heat-preservation pipeline.
Background technique
The Main Function of insulation pipe is to the pipeline internal medium insulation, and the high-temp liquid conveyance conduit at present adopts pure cast iron, Steel material pipe, but its thermal insulation property is poor, liquidborne noise is large; Existing industrial heating power metallic conduit adopts traditional Insulation mostly, and namely the outer surface at metallic conduit covers the one layer of heat preservation material.These thermal insulating materials have many genotypes material because thermal insulation layer is thicker, and seam is many, bad adhesion with base material, anti-vibration not, working life is short, therefore all can not satisfy the technical requirements of various heating power metallic conduits from the aspects such as convenience, heat insulation effect and Applicable scope of construction.
Summary of the invention
The objective of the invention is the defective for prior art, provide a kind of heat preservation and energy conservation effects significantly, easy construction and high-efficiency heat-preservation pipeline applied widely.
The objective of the invention is to solve by the following technical programs:
A kind of high-efficiency heat-preservation pipeline, described tube wall are followed successively by inner tube, jacket pipe, carbon foamed substrate thermal insulation layer and heat-preservation cotton layer from inside to outside, and described jacket pipe is enclosed within the outside of inner tube, are provided with toroidal cavity between inner tube and the jacket pipe.
Described carbon foamed substrate thermal insulation layer curing is bonded in the outer surface of jacket pipe and the internal surface of heat-preservation cotton layer.
Described inner tube and jacket pipe adopt stainless steel to make.
The present invention has the following advantages compared to existing technology:
High-efficiency heat-preservation pipeline of the present invention is bonding on the basis of two-layer thermal insulating material in the outside of Stainless Steel Tube, also is provided with for the toroidal cavity of heat transfer medium flows, not only to have utilized the heat insulation principle of cavity, and can utilize the cavity heat supply between Stainless Steel Tube.
The present invention is simple for structure, good heat preservation performance, the hydrodynamic noise of fluid of having reduced, and one-body molded, without seam, and has the advantages that anti-vibration is strong, the life-span is long, and is applied widely.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-inner tube; 2-jacket pipe; 3-carbon foamed substrate thermal insulation layer; 4-heat-preservation cotton layer; 5-toroidal cavity.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1: a kind of high-efficiency heat-preservation pipeline, the tube wall of high-efficiency heat-preservation pipeline are followed successively by inner tube 1, jacket pipe 2, carbon foamed substrate thermal insulation layer 3 and heat-preservation cotton layer 4 from inside to outside.Inner tube 1 and jacket pipe 2 all adopt stainless steel to make, jacket pipe 2 is enclosed within the outside of inner tube 1, and between inner tube 1 and jacket pipe 2, be provided with toroidal cavity 5, play on the one hand the heat insulation effect of cavity, also can in toroidal cavity 5, be filled with mobile heat transfer medium, directly the flowing medium in the inner tube 1 is incubated even heat.3 curing of carbon foamed substrate thermal insulation layer are bonded in the outer surface of jacket pipe 2 and the internal surface of heat-preservation cotton layer 4, and the bonding effect of carbon foamed substrate thermal insulation layer 3 is good, not only plays the effect of insulation, also can reduce the hydrodynamic noise of fluid, anti-vibration.
The technology that the present invention does not relate to all can be realized by prior art.
Claims (3)
1. high-efficiency heat-preservation pipeline, it is characterized in that described tube wall is followed successively by inner tube (1), jacket pipe (2), carbon foamed substrate thermal insulation layer (3) and heat-preservation cotton layer (4) from inside to outside, described jacket pipe (2) is enclosed within the outside of inner tube (1), is provided with toroidal cavity (5) between inner tube (1) and the jacket pipe (2).
