Abstract
The utility model discloses an anti-freezing device of a pipeline, which comprises a pipe body, wherein a pipeline is arranged in the pipe body, and the key point of the technical scheme lies in that an elastic body, which is compressed under the squeezing, when the liquid in the pipeline is frozen is arranged in the pipeline, and longitudinally extends in the pipeline. The anti-freezing device of the pipeline overcomes the defects of the prior art, and effectively prevents the pipeline from cracking when the liquid therein is frozen.
Description
[technical field]
The present invention relates to the freeze proof device of a kind of freezing prevention tubing.
[background technique]
When temperature about zero degree or during subzero, volumetric expansion causes pipeline burst when carrying the pipeline of liquid usually to freeze owing to liquid, and present existing settling mode one is electric heating; The 2nd, in pipeline, add antifreeze liquid; The 3rd, quit work and with liquid emptying; Electric heating: lost efficacy and power consumption during because of heating-up temperature height, power failure or damage; Add antifreeze liquid: in some application is unaccommodated, as: bath water etc.; Liquid emptying: hell to pay, too all there is defective in waste.
[summary of the invention]
The present invention seeks to have overcome the deficiencies in the prior art, a kind of freeze proof device of freezing prevention tubing of pipeline burst when preventing effectively that liquid from freezing is provided.
The present invention is achieved through the following technical solutions:
The freeze proof device of a kind of freezing prevention tubing, comprise body 10, be provided with pipeline 1 in the described body 10, it is characterized in that: be provided with in the described pipeline 1 that its volume is because of the compressed elastomer 2 that is squeezed when the liquid in the pipeline 1 freezes, described elastomer 2 is along pipeline 1 longitudinal extension.
The freeze proof device of aforesaid freezing prevention tubing is characterized in that: be provided with in the described elastomer 2 and be used to heat the electric heating wire 3 that thaws.
The freeze proof device of aforesaid freezing prevention tubing is characterized in that: described elastomer 2 is strip, is arranged on the central authorities of described pipeline 1.
The freeze proof device of aforesaid freezing prevention tubing is characterized in that: described elastomer 2 is tubulose, and the outer wall of described elastomer 2 is close to pipeline 1 inwall.
The freeze proof device of aforesaid pipeline is characterized in that: it also comprises the temperature controller assembly.
Compared with prior art, the present invention has following advantage:
1, the present invention is provided with contractile elastomer in pipeline, utilizes elastomeric physical property to prevent that liquid from freezing and causes pipeline burst when expanding;
2, be provided with electric heating wire in the elastomer of the present invention, the liquid of being convenient to freeze in the pipeline thaws;
3, the present invention can not pollute and mix, and need not to add in liquid antifreezing solution;
4, the present invention can guarantee that under the least favorable condition object of protection is unlikely to damage.

[embodiment]
The freeze proof device of a kind of freezing prevention tubing comprises body 10, is provided with pipeline 1 in the described body 10, is provided with in the described pipeline 1 that its volume is because of the compressed elastomer 2 that is squeezed when the liquid in the pipeline 1 freezes, and described elastomer 2 is along pipeline 1 longitudinal extension.
Be provided with in the described elastomer 2 and be used to heat the electric heating wire 3 that thaws.Also comprise the temperature controller assembly in the freeze proof device, supply pipe is heated to more than the liquid freezing temperature when water pipe is in freezing state.
Described elastomer 2 can be strip, is arranged on the central authorities of described pipeline 1.Described elastomer 2 also can be tubulose, and the outer wall of described elastomer 2 is close to pipeline 1 inwall.
Aged deterioration can durablely not take place in water pipe elastic material when the condition of high temperature, and electrically-heated-wire adopts low resistance low voltage and current flow heats mode.
Described body can be iron pipe or rigid walls pipelines such as steel pipe or copper pipe, and described elastomer can be materials such as rubber or silica gel.The present invention utilizes elastomer to damage when the principle of passive compression under the freezing situation protects the rigidity tube wall to be unlikely in freezing expansion, if add the work that electrically-heated-wire can also recover the water pipe network in the normal back of power supply in elastomer.Realized the protection of water pipe under the harshest state with existing comparing regardless of anti-icing freeze techniques, can be because of having a power failure and the malfunctioning damage that causes water pipe of anti-icer.
Working principle of the present invention:
A) when the water pipe ambient temperature is lower than zero degree, power supply just often can adopt electrothermal method that water pipe is heated in case the water stopping tube bursting by freezing;
Water when b) power supply is undesired in the water pipe is with freezing, and at this moment elastic material is with the expansion absorption of ice;
C) when power supply is normal once more control system heating makes water pipe recover proper functioning to water pipe by electrically-heated-wire.
