Abstract
It the utility model is related to pipe insulation field, a kind of more particularly to fireproof heat insulating pipe, including instrumentation tubes, outer protection tube outside instrumentation tubes and the fire-retardant heat insulation layer being filled between instrumentation tubes and outer protection tube, the fire retardant thermal insulation material that the non-ignitable thermal insulation material or combustibility rank for the use of combustibility rank being A grades are B1 is used as packing material, both it ensure that insulation capacity, non-ignitable fire prevention again, eliminate the security risks such as fire, outer protection tube uses thin-walled spiral duct, compared with common polythene outer protection tube, the outer protection tube is metal material, it is non-ignitable, for safe and reliable under aerial particularly city integrated piping lane environment.
Description
Technical field
It the utility model is related to pipe insulation field, more particularly to a kind of fireproof heat insulating pipe.
Background technology
At present, the utilidor that heating network uses, its outer protection tube are typically polyethylene outer protective pipe, and insulating layer is polyurethane
Cellular insulant.When piping network installation is among aerial or city integrated piping lane, the pipeline of the structural material cannot meet
It is required that.First, the easy to aging, embrittlement if polyethylene outer protective pipe is exposed to the sun in the sun for a long time, polyethylene is inflammable material again, in pipe
Using there are security risk in corridor.Secondth, used polyurethane foam is inflammable, and either aerial or city integrated piping lane makes
With being all dangerous there are security risk, cannot be used in city integrated piping lane, this point is in country《City integrated piping lane
Engineering legislation》(GB50838-2015) clear stipulaties heat distribution pipeline and its accessory thermal insulation material should use fire retardant or non-ignitable in
Material.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, there is provided one kind can be used for
Aerial pipeline and city integrated piping lane pipeline, its insulation construction have the fireproof heat insulating pipe of non-ignitable performance.
The utility model is to be achieved by the following technical programs：
A kind of fireproof heat insulating pipe, it is characterised in that outer protection tube including instrumentation tubes, outside instrumentation tubes and be filled in work
Fire-retardant heat insulation layer between pipe and outer protection tube, the instrumentation tubes outside are uniformly fixed with a plurality of steel band along instrumentation tubes extending direction
Ring, by steel band around being formed, the steel band opening is being worked any steel band ring by metal clamps around being fixedly clamped
Guan Shang, multiple locating supports are evenly distributed with steel band, and the locating support cross section is trapezoidal, and locating support bottom is laterally opened
There is perforative packing hole, locating support is fixed in instrumentation tubes by steel band ring through packing hole, the positioning branch on any steel band ring
Frame is overlapped with the locating support on other steel band rings along the projection of work tube axis direction, and it is fixed to be provided with the locating support inner wall
Position hole.
Preferably, the locating support bottom is integrally formed with multiple support ribs.
Preferably, the outer protection tube is thin-walled spiral duct.
Preferably, the fire-retardant heat insulation layer is by non-ignitable thermal insulation material or combustibility rank of the combustibility rank for A grades
It is made of the fire retardant thermal insulation material of B1.
The beneficial effects of the utility model are：
The non-ignitable thermal insulation material that combustibility rank is A grades or the fire retardant thermal insulation material that combustibility rank is B1 are used
As packing material, insulation capacity, but also non-ignitable fire prevention not only ensure that, eliminate the security risks such as fire, outer protection tube uses
Thin-walled spiral duct, compared with common polythene outer protection tube, which is metal material, non-ignitable, for aerial particularly city
Used safely under city's pipe gallery environment, there is fire protecting performance, pipe network operation is safe and reliable.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of locating support.
In figure：1. instrumentation tubes, 2. outer protection tubes, 3. fire-retardant heat insulation layers, 4. steel band rings, 5. locating supports, 6. packing holes, 7. is fixed

Embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings
The utility model is described in further detail with most preferred embodiment.
As shown in the figure, the utility model include instrumentation tubes 1, the outer protection tube 2 outside instrumentation tubes and be filled in instrumentation tubes and
Fire-retardant heat insulation layer 3 between outer protection tube, the instrumentation tubes outside are uniformly fixed with a plurality of steel band ring 4 along instrumentation tubes extending direction,
By steel band around being formed, the steel band opening is surround and is fixedly clamped in instrumentation tubes any steel band ring by metal clamps
On, steel band optimum width is 18mm, thickness 0.5mm, and multiple locating supports 5, the locating support are evenly distributed with steel band
Cross section is trapezoidal, and locating support bottom is laterally provided with perforative packing hole 6, and steel band ring fixes locating support through packing hole
In instrumentation tubes, locating support and throwing of the locating support on other steel band rings along work tube axis direction on any steel band ring
Shadow overlaps, and locating support can ensure that instrumentation tubes are coaxial with outer protection tube, location hole 7 is provided with the locating support inner wall.
Preferably, the locating support bottom supports formation bottom branch between rib integrally formed with multiple support ribs 8
Cavity is supportted, the iris action to packing material can be reduced, the thermal insulation material of filling is protected full of whole insulation sheaf space, enhancing
Warm heat insulation.
Preferably, the outer protection tube is thin-walled spiral duct.
Preferably, the fire-retardant heat insulation layer is by non-ignitable thermal insulation material or combustibility rank of the combustibility rank for A grades
It is made of the fire retardant thermal insulation material of B1.
The non-ignitable thermal insulation material that combustibility rank is A grades or the fire retardant thermal insulation material that combustibility rank is B1 are used
As packing material, insulation capacity, but also non-ignitable fire prevention not only ensure that, eliminate the security risks such as fire, outer protection tube uses
Thin-walled spiral duct, compared with common polythene outer protection tube, which is metal material, non-ignitable, for aerial particularly city
Used safely under city's pipe gallery environment, there is fire protecting performance, pipe network operation is safe and reliable.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
