Abstract

The utility model provides a frost crack prevention pipe structure, which is provided with a pipe body. A compressible body with an inner cavity is arranged in the pipe body, and the inner cavity of the compressible body is isolated from the inner cavity of the pipe body. In the frost crack prevention pipe structure, the compressible body is compressed when in freezing, and the volumetric expansion due to frozen water is offset, and thereby, the pipeline is prevented from frost crack. The frost crack prevention pipe structure has good frost crack prevention effect, simple and reasonable structure, convenient construction and low manufacturing cost. The frost crack prevention pipe structure can be used for solar water heater pipelines, outdoor tap water pipelines and other outdoor pipelines, i.e. the frost crack prevention pipe structure has wide application range.

Description

A kind of anti-bursting by freezing tubular structure

Technical field

The utility model provides a kind of tubular structure of preventing bursting by freezing.

Background technology

In the winter of northern area, the water capacity in the piping outside the house is easily frozen, and the back water expansion meeting of freezing cracks pipeline and container.The measure of present anti-bursting by freezing is normally at the coated outside heat insulating material of pipeline, the construction technology complexity, and cost is higher, and anti-bursting by freezing effect is relatively poor, and temperature is crossed when low, still the bursting by freezing phenomenon can take place.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of anti-bursting by freezing tubular structure, to improve anti-bursting by freezing effect.

The utility model is achieved in that a kind of anti-bursting by freezing tubular structure, and it has body, and the be compressed body of band inner chamber is arranged in the body, and the inner chamber and the tube cavity that can be compressed body are isolated.

Adopt the anti-bursting by freezing tubular structure of said structure, can be compressed body and when icing, be compressed, the volume expansion that has produced when having offset water freezing, thus avoided pipeline by bursting by freezing, anti-bursting by freezing is effective.And simple and reasonable, easy construction, low cost of manufacture.Can be used for solar energy water heater pipe, outdoor tap water pipeline and other yard piping, applied range.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.

As shown in drawings, a kind of antifreeze tubular structure that splits of the utility model, it has body 1, and the be compressed body 2 of band inner chamber is arranged in the body, and the inner chamber and the tube cavity that can be compressed body are isolated.

Can be compressed body under the situation of not freezing, occupy the segment space in the body.When water freezing, be compressed, volume reduces, the volume expansion that has produced when having offset water freezing.This volume that is compressed body reduces degree, the volume enlarged degree in the time of can being slightly larger than the water freezing in the tube cavity.

As shown in Figure 2, the described body 2 that is compressed is the inlet pipe 21 that is connected together, the flexible pipe body that goes out pipe 22 formations.When the fluid pressure in the body is higher, can charge into the air of certain pressure in the flexible pipe body.Fluid pressure in body is lower, when flexible pipe intensity is enough, have the air of natural pressure to get final product in the flexible pipe.Like this, can send into hot gas or hot water, the body and the water that can be compressed between the body are thawed by flexible pipe body.Flexible pipe body can be installed in the body by bar 3.

The described body that is compressed also can adopt single tube form shown in Figure 1.

The described body 2 that is compressed is the bubble pad 23 of body 1 inwall inboard.The available plastics of bubble pad, rubber or plastic cement or other suitable materials are made.The structure of this bubble pad is identical with the plastic blister pad packing material that plays cushioning effect commonly used at present.Each plastic blister on the bubble pad or the common formation of rubber bubble inner chamber can be compressed the inner chamber of body, and the pressure of the air in the inner chamber should be suitable, neither can be squeezed flatly by the fluid pressure in the body, when water freezing, can be squeezed again and reduce volume.

Telescopic bushing pipe 11 is arranged in the described body 1.At this moment, body is the plastic-aluminum pipe, and bushing pipe is an aluminum pipe wherein.Can have a plurality of on the cross section of aluminum pipe as Fig. 4, warpage shown in Figure 5.Like this, when water freezing produced volume expansion, lining pipe was with spreading radially, with the anti-bursting by freezing effect of further raising.
