Description
Technical field
The utility model relates to a kind of anti-freeze type plastic pipe.
Background technique
Yard piping after installation is complete, usually needs to spray antifreeze sponge at the outer surface of pipeline, but due to the outer surface of pipeline be smooth, therefore the area of contact of the outer surface of antifreeze sponge and pipeline is limited, and therefore antifreezing effect is poor.
Freezing prevention tubing of the prior art, just adopts simple antifreeze sponge mostly simultaneously, and therefore when antifreeze sponge occurs damaged, cold air directly attacks the outer surface at pipeline, causes pipeline by bursting by freezing.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of anti-freeze type plastic pipe, and this device can carry out antifreeze to pipeline body from inside and outside simultaneously, improves the heat insulation effect of pipeline body, avoids pipeline body by bursting by freezing.
For solving the problem, the utility model adopts following technological scheme:
A kind of anti-freeze type plastic pipe, comprise pipeline body, and be arranged on the Anti-freezing pipeline of described pipeline body outside, interlayer is formed between described Anti-freezing pipeline and described pipeline body, heat-preservation cotton is provided with in interlayer, described pipeline body has a undulatory outer surface, the outer surface of described pipeline body is provided with antifreeze sponge, the internal surface of described antifreeze sponge and the undulatory outer surface of described pipeline body fit, one end of described pipeline body has the outside thread connected, the other end of described pipeline body be provided with described outside thread with the use of internal thread.
As preferred technological scheme, described pipeline body and described Anti-freezing pipeline are PVC plastic pipeline.
As preferred technological scheme, the thickness of described pipeline body is 1mm ~ 2mm.
As preferred technological scheme, the thickness of described Anti-freezing pipeline is 2mm ~ 3mm.
As preferred technological scheme, the wall thickness of described heat-preservation cotton is 2mm ~ 3mm.
The beneficial effects of the utility model are: in this device, Anti-freezing pipeline have employed a undulatory outer surface, add the area of contact between antifreeze sponge and Anti-freezing pipeline, and then add the resistance to frost of Anti-freezing pipeline, between Anti-freezing pipeline and pipeline body, be provided with heat-preservation cotton simultaneously, further block outside cold air to the invasion and attack of pipeline body, avoid pipeline body by bursting by freezing, this device adopts dual antifreeze simultaneously, even if there is space in antifreeze sponge, still can keep the good resistance to frost of pipeline body, the structure of this device is comparatively simple simultaneously, manufacture more for convenience, be applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is plan view of the present utility model;
Fig. 2 is plan view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult a kind of anti-freeze type plastic pipe shown in Fig. 1 and Fig. 2, comprise pipeline body 1, and be arranged on the Anti-freezing pipeline 2 of described pipeline body 1 outside, interlayer is formed between described Anti-freezing pipeline 2 and described pipeline body 1, heat-preservation cotton 3 is provided with in interlayer, described pipeline body 1 has a undulatory outer surface, the outer surface of described pipeline body 1 is provided with antifreeze sponge 4, the internal surface of described antifreeze sponge 4 and the undulatory outer surface of described pipeline body 1 fit, one end of described pipeline body 1 has the outside thread 101 connected, the other end of described pipeline body 1 be provided with described outside thread 101 with the use of internal thread (not shown).
A preferred embodiment in the utility model, described pipeline body 1 and described Anti-freezing pipeline 2 are PVC plastic pipeline.
A preferred embodiment in the utility model, the thickness of described pipeline body 1 is 2mm.
A preferred embodiment in the utility model, the thickness of described Anti-freezing pipeline 2 is 3mm.
A preferred embodiment in the utility model, the wall thickness of described heat-preservation cotton 3 is 3mm.
The beneficial effects of the utility model are: in this device, Anti-freezing pipeline have employed a undulatory outer surface, add the area of contact between antifreeze sponge and Anti-freezing pipeline, and then add the resistance to frost of Anti-freezing pipeline, between Anti-freezing pipeline and pipeline body, be provided with heat-preservation cotton simultaneously, further block outside cold air to the invasion and attack of pipeline body, avoid pipeline body by bursting by freezing, this device adopts dual antifreeze simultaneously, even if there is space in antifreeze sponge, still can keep the good resistance to frost of pipeline body, the structure of this device is comparatively simple simultaneously, manufacture more for convenience, be applicable to promoting the use of.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
