[embodiment]
The freeze proof method of a kind of freezing prevention tubing is provided with in being used to carry the pipeline 1 of liquid 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.
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, perhaps for twine the helical of spiraling in pipeline 1.
A kind of freeze proof device of freezing prevention tubing that is used for the above-mentioned freeze proof method of freezing prevention tubing, comprise body 10, be provided with pipeline 1 in the described body 10, 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.
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.
