Abstract
A fire-resistant thermal isolation insulation tube comprises an insulation layer, a thermal isolation packing layer, a low-expansion alloy shell and a fire-resistant protection material layer from interior to exterior in sequence. The thermal isolation packing layer is internally provided with a tube supporting frame. The insulation layer is made of a carbon fiber insulation material. The thermal isolation packing layer is made of kieselguhr. The low-expansion alloy shell is made of ferronickel materials. The fire-resistant protection material layer is made of silicon carbide. The fire-resistant thermal isolation insulation tube has the advantages that high-temperature open fire can be effectively prevented from damaging a tube stock and circuits in a cavity of the tube stock, tube stock deformation and fracture caused by the high temperature are prevented, and more serious damage caused by the short circuit of the inner circuits is prevented.
Description
Technical field
The present invention relates to flame shield material field, particularly a kind of fireproof heat-insulating insulated tube.
Background technology
Increasing along with current engineering construction, also more and more higher to engineering fireproof demand, when fire occurs, intact electronic circuit not only can be helpful to fire rescue, the secondary that can also prevent the line short caused due to high temperature naked light from causing is on fire, causes larger injury and loss.
Existing fire prevention cable tubing fire resistance is not high, under long-time calcination, can be out of shape, cause fire resistance to decline, make circuit impaired due to thermal expansion.Meanwhile, owing at high temperature likely causing internal short-circuit, form unknown hazard of catch fire to external world.
Summary of the invention
The present invention, for solving the problems of the technologies described above, improves fire resistance and the insulation property of tubing.A kind of fireproof heat-insulating insulated tube is provided.The technical scheme adopted is as follows:
A kind of fireproof heat-insulating insulated tube, is followed successively by insulating barrier, adiabatic packed layer, low-expansion alloy shell, flame shield material layer from the inside to the outside.
In described adiabatic packed layer, tube support frame is installed.
Described insulating barrier is carbon fiber insulating material.
Described adiabatic packed layer is diatomite.
Described low-expansion alloy shell is iron-nickel alloy material.
Described flame shield material layer is carborundum.
Wherein, low-expansion alloy shell can make body under high temperature fire conditions, does not produce by thermal deformation, and protection tubing inside cavity cable is not damaged.Tube support frame also has the effect of reinforced pipe body structure intensity, and the impact resistance of body is increased greatly.Adiabatic packing material diatomite has good heat-insulating property, can ensure that pipe interior can not cause short circuit because temperature is too high.The carbon fiber insulating material of insulating barrier has to the circuit in tubing cavity the effect that protection prevents short circuit.The carborundum of flame shield material layer, can effectively prevent naked light to the injury of body.
Beneficial effect of the present invention is: effectively can prevent the circuit of high temperature naked light to tubing and tubing inside cavity from causing damage, prevent high temperature from causing pipe deformations to rupture, prevent internal wiring short circuit from causing larger damage.

Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with Fig. 1, the present invention being further elaborated, but not limiting protection scope of the present invention.
A kind of fireproof heat-insulating insulated tube, is followed successively by insulating barrier 5, adiabatic packed layer 3, low-expansion alloy shell 2, flame shield material layer 1 from the inside to the outside.
In described adiabatic packed layer 3, tube support frame 4 is installed.
Described insulating barrier 5 is carbon fiber insulating material.
Described adiabatic packed layer 3 is diatomite.
Described low-expansion alloy shell 2 is iron-nickel alloy material.
Described flame shield material layer 1 is carborundum.
Wherein, low-expansion alloy shell 2 can make body under high temperature fire conditions, does not produce by thermal deformation, and protection tubing cavity 6 Internal cable is not damaged.Tube support frame 4 also has the effect of reinforced pipe body structure intensity, and the impact resistance of body is increased greatly.Adiabatic packing material diatomite has good heat-insulating property, can ensure that pipe interior can not cause short circuit because temperature is too high.The carbon fiber insulating material of insulating barrier 5 has to the circuit in tubing cavity 6 effect that protection prevents short circuit.The carborundum of flame shield material layer 1, can effectively prevent naked light to the injury of body.
Be more than a kind of embodiment of the present invention, the correlation function that insulation and thermal insulation is fire-resistant can be realized, but do not limit concrete protection range of the present invention.
