To achieve the above object, the utility model provides a kind of overall plastic insulating tube of flame-retardant and anti-static, including flame-retardant layer, guarantor
Warm layer and instrumentation tubes, conductive black and fire retardant are evenly distributed with the flame-retardant layer, the guarantor is wrapped in outside the flame-retardant layer
Warm layer, the heat-insulation layer are wrapped in the instrumentation tubes outside, and the inwall of the instrumentation tubes is shiny surface.
Preferably, the flame-retardant layer thickness is 3-10mm, and the fire retardant is the mixture of halogen flame and antimony oxide.
Preferably, the heat-insulation layer is hard polyurethane foam layer, and the hard polyurethane foam thickness degree is 10-
60mm。
Preferably, the instrumentation tubes are pressure-bearing plastic pipe, and the pressure-bearing plastic pipe is biaxially oriented polychloroethylene pipes, double
The a diameter of 110mm-630mm of axle orientation polychloroethylene pipes.
Preferably, the shiny surface absolute roughness is 0.009.
Therefore, the utility model uses a kind of overall plastic insulating tube of flame-retardant and anti-static of said structure, suitable for refrigeration of underground mine
Pipeline, there is good anti-flammability and antistatic property, the instrumentation tubes have good corrosion resistance, so as to improve the pipeline longevity
Life, the inwall of the instrumentation tubes is shiny surface, improves stability and the pressure drop of pipeline liquid, is more beneficial for adjusting pipeline hydraulic
Balance.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Embodiment
Embodiment 1
Fig. 1 is a kind of overall plastic insulating tube cross-sectional view of flame-retardant and anti-static of the utility model, and Fig. 2 is the utility model one
The kind overall plastic insulating tube schematic perspective view of flame-retardant and anti-static.As shown in Figure 1-2, the overall plastic insulating tube of a kind of flame-retardant and anti-static, including resistance
Firing layer 1, heat-insulation layer 2 and instrumentation tubes 3, the thickness of flame-retardant layer 1 is 3-10mm, and the thickness of flame-retardant layer 1 uses 5.5mm in the present embodiment,
Heat-insulation layer 2 and instrumentation tubes 3, which can be effectively protected, to be damaged, it is often more important that be evenly distributed with conduction in flame-retardant layer 1
Carbon black and fire retardant, fire retardant are the mixture of halogen flame and antimony oxide, and the addition of fire retardant causes pipeline in high temperature
It will not burn and cause the accident under environment, the conductive black of addition causes flame-retardant layer 1 to have antistatic property while also increases resistance
Performance is fired, so as to which flame-retardant layer 1 has good anti-flammability and antistatic property.Heat-insulation layer 2 is wrapped in outside flame-retardant layer 1, outside heat-insulation layer 2
It is wrapped in instrumentation tubes 3, heat-insulation layer 2 is hard polyurethane foam layer, and hard polyurethane foam thickness degree is 10-60mm, the present embodiment
Heat-insulation layer 2 uses 40mm thickness so that heat-insulation layer 2 has good thermal and insulating performance.The inwall of instrumentation tubes 3 is shiny surface
31, the absolute roughness of shiny surface 31 is 0.009, and instrumentation tubes 3 are pressure-bearing plastic pipe, and pressure-bearing plastic pipe is biaxially oriented polyvinyl chloride
Tubing, biaxially orienting polyvinyl chloride pipe diameter are 110mm-630mm, and the present embodiment uses a diameter of 250mm, and biaxial orientation gathers
Vinyl chloride tubing improves the intensity and toughness of tubing, produces thin slice hierarchy by tubing after biaxial orientation, can hinder
Hinder crackle in the material by the way that the toughness of tubing is greatly improved.The absolute roughness of shiny surface 31 is 0.009, common
Steel pipe absolute roughness is 0.15, it is clear that shiny surface 31 is more smooth than steel pipe inner wall, less so as to have during trandfer fluid
Frictional resistance and adhesive force, coefficient of friction is smaller, and in the case of same inner diameter and same traffic, the pressure drop of unit length will
It is more much smaller than steel pipe, and as the increase pressure drop of caliber and flow is more obvious, instrumentation tubes 3 also have excellent chemically-resistant rotten
Erosion and abrasion resistance properties, ensure that the hydraulic characteristic(s) of pipe network is steady in a long-term, can easily be accommodated the hydraulic equilibrium of pipe network, light weight installation side
Just, short construction period, low heat conductivity performance, service life will be grown compared to steel pipe.
Therefore, the utility model uses a kind of overall plastic insulating tube of flame-retardant and anti-static of said structure, suitable for refrigeration of underground mine
Pipeline, there is good anti-flammability and antistatic property, instrumentation tubes 3 have good corrosion resistance, so as to improve pipeline life,
The inwall of instrumentation tubes 3 is shiny surface 31, improves stability and the pressure drop of pipeline liquid, is more beneficial for regulation pipeline hydraulic and puts down
Weighing apparatus.
Above is specific embodiment of the present utility model, but the scope of protection of the utility model should not be limited to this.Appoint
How those skilled in the art are in the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in,
It should all cover within the scope of protection of the utility model, therefore the scope of protection of the utility model should be limited with claims
Fixed protection domain is defined.
