Abstract
The invention discloses a thermal insulation hose, which comprises an inner layer of the hose and an outer layer of the house, wherein a certain space gap is formed between the inner layer and the outer layer of the hose so as to form an annular space, and the inner layer and the outer layer of the hose are connected through an elastic cylinder. The thermal insulation hose provided by the invention is characterized in that a part of heat of fluid can be dissipated through the annular space when the fluid circulates in the inner hose due to the certain space gap between the inner and outer layers of the hose; on one hand, due to the elastic cylinder between the inner layer and the outer layer, the relative positions of the inner layer and the outer layer can not be changed due to the elasticity when the hose is bent; and on the other hand, the elastic cylinder can stabilize the gap distance between the inner layer and the outer layer of the hose, so that the service life of the hose is prolonged.
Description
Technical field
The present invention relates to a kind of flexible pipe, particularly a kind of heat-insulating hose belongs to technical field of hoses.
Background technique
Normally used flexible pipe is metallic hose, and it generally is made of metal bellows and wire net; Some places then are to use an easy plastic flexible pipe, when this flexible pipe needs long-time crooked the use, and easily aging, distortion, alternating stress intensity is inadequate, and effect of heat insulation is poor, and the life-span is low.
Summary of the invention
Technical problem to be solved by this invention is a kind of heat-insulating hose that provides for the defective of above-mentioned prior art existence; For solving its technical problem, the technical solution adopted in the present invention is: a kind of heat-insulating hose, comprise the flexible pipe body, described flexible pipe body comprises flexible pipe internal layer and flexible pipe skin, be provided with certain spatial joint clearance between described flexible pipe internal layer and the skin, form an annular space, be connected by elastic cylinder between described flexible pipe internal layer and the skin.
Further, described internal layer flexible pipe and outer flexible pipe are made by resin material.
Further, the thickness of described internal layer flexible pipe and outer flexible pipe is 3-5mm.
Further, the diameter of described elastic cylinder is 3mm.
Further, described elastic cylinder is made by the PUV elastic rubber material.
Further, described elastic cylinder is evenly distributed in the described annular space.
The invention has the beneficial effects as follows: owing between the internal and external layer flexible pipe certain space gap is arranged, fluid can leave a part of heat by annular space when the internal layer flexible pipe circulates, because flexible cylinder between internal layer and the skin, when flexible pipe was subject to bending, because the elastic force effect, internal layer and outer field relative position can not change, anti-alternating stress intensity is high, on the other hand, elastic cylinder can be stablized the spatial joint clearance distance between the internal and external layer flexible pipe, has prolonged the working life of flexible pipe.
Description of drawings
Accompanying drawing is used to provide a further understanding of the present invention, and consists of the part of specification, is used for together with embodiments of the present invention explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is structural representation of the present invention;
The sequence number of marking is described as follows among Fig. 1: the 1-elastic cylinder, the 2-flexible pipe is outer, 3-flexible pipe internal layer.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, is not intended to limit the present invention.
Referring to shown in Figure 1, a kind of easy heat radiation flexible pipe comprises the flexible pipe body, described flexible pipe body comprises flexible pipe internal layer 3 and flexible pipe skin 2, be provided with certain spatial joint clearance between the described flexible pipe internal layer 3 and outer 2, form an annular space, 2 are connected by elastic cylinder 1 between described flexible pipe internal layer 3 and the skin.Described internal layer flexible pipe 3 and outer flexible pipe 2 are made by resin material.
Described internal layer flexible pipe 3 is 3-5mm with the thickness of outer flexible pipe 2.The diameter of described elastic cylinder 1 is 3mm.Described elastic cylinder 1 is made by the PUV elastic rubber material.Described elastic cylinder 1 is evenly distributed in the described annular space.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment the present invention is had been described in detail, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
