Description
Technical field
This utility model relates to pipe technology field, is specifically related to a kind of novel gas pipeline based on Graphene.
Background technology
Gas pipeline, is usually used to carry the flammable explosive gas such as natural gas, coal gas, in order to ensure that course of conveying does not leaks, so that causing the most serious security incident, requires higher to the air-tightness of gas pipeline, corrosion resistance etc..The most common gas pipeline is all to use bimetal pipe system to become, inner layer metal body conveying gas, outer layer metal body protection inner layer metal body.But above-mentioned gas pipeline is in use, finding following shortcoming: one is that the Corrosion Protection of outer layer metal body is strong, uses of long duration, there is potential safety hazard in easy corrosion；Two is that the heat conductivility of metal is generally preferable, in the environment of high temperature or low temperature, easily affects the stability of internal gas, limits the range of gas pipeline；Three is the against shock poor-performing of double-level-metal, and gas can produce bigger noise when transport.
Utility model content
In order to solve the problems such as the anticorrosive property of existing gas pipeline is poor, safety coefficient is low, noise is big; this utility model provides a kind of gas pipeline rational in infrastructure, easy to use; can be effectively protected the gas in conveyance conduit, will not produce again the biggest noise, concrete technical scheme is as follows:
A kind of novel gas pipeline based on Graphene, including inner tube, damp-proof layer, heat-insulating, fire-preventing layer and outer tube, inner tube is that hollow-core construction is for transporting gas, it is coated with by damp-proof layer outside inner tube, fireprotection layer cladding it is insulated outside damp-proof layer, be coated with by outer tube outside heat-insulating, fire-preventing layer, outer tube be externally coated with graphene layer.
As a kind of preferred version of the present utility model, the thickness of described graphene layer is 10～100 μm.
As a kind of preferred version of the present utility model, said inner tube uses PVC material to make.
As a kind of preferred version of the present utility model, being provided with shakeproof layer between described damp-proof layer and inner tube, shakeproof layer is made up of elastomeric material.
As a kind of preferred version of the present utility model, the material of described heat-insulating, fire-preventing layer is glass fibre or ceramic fibre or mullite fiber.
As a kind of preferred version of the present utility model, the material of described damp-proof layer is foamed plastic.
The beneficial effects of the utility model: compared to the bimetal pipe of prior art; gas pipeline layer structure of the present utility model is reasonable; can effectively protect the flammable explosive gas of tubular body; prevent security leak; graphene layer has good heat stability and chemical stability; corrosion resistance is strong; can coat for different metal material top layer; range is wide; heat-insulating, fire-preventing layer can be prevented effectively from the gas of inner tube and spontaneous combustion occurs in high temperature environments; it addition, shakeproof layer can reduce noise and the vibrations that the gas of inner tube produces in transportation.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model layer structure；
Fig. 2 is the zoomed-in view in Fig. 1 at A.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described further:
As depicted in figs. 1 and 2, a kind of novel gas pipeline based on Graphene, including inner tube 1, damp-proof layer 2, heat-insulating, fire-preventing layer 3 and outer tube 4, inner tube 1 is used for transporting gas for hollow-core construction, inner tube 1 is outside to be coated with by damp-proof layer 2, damp-proof layer 2 is outside to be insulated fireprotection layer 3 and is coated with, and heat-insulating, fire-preventing layer 3 is outside to be coated with by outer tube 4, outer tube 4 be externally coated with graphene layer 5.
The thickness of graphene layer 5 is 10～100 μm, has thickness advantage thin, lightweight, can be effectively protected outer tube 4 through substantial amounts of it is demonstrated experimentally that the thickness of graphene layer 5 is preferably 50 μm, be readily formed again, saves material.Graphene layer 5 can form through spraying in 2 hours in the environment of 150～250 DEG C；Or in the environment of 100～150 DEG C, form through spraying in 8 hours.
Inner tube uses PVC material to make, it is possible to decrease use the cost of metal material.Being provided with shakeproof layer 6 between damp-proof layer 2 and inner tube 1, shakeproof layer 6 is made up of elastomeric material, has both had the effect of buffer protection, can reduce again noise and vibrations that gas produces in transportation, reduces the impact on surrounding enviroment, and the thickness of shakeproof layer 6 is 3mm～7mm.
The material of heat-insulating, fire-preventing layer 3 is glass fibre or ceramic fibre or mullite fiber, thickness is 5～11mm, have lightweight, high temperature resistant, Heat stability is good, thermal conductivity are low, specific heat is little and the advantage such as mechanical resistant vibrations, can effectively completely cut off the impact on conveying gas of the external high temperature environment, prevent because temperature is too high, produce self-destruction phenomenon.It addition, the material of damp-proof layer 2 is foamed plastic, thickness is 6～13mm, can effectively absorb the moisture in air, prevent from making moist.
In a word, gas pipeline of the present utility model uses multiple structure to constitute, and has the effect of anticorrosion, damping, protection against the tide, high temperature-proof simultaneously, can use under the adverse circumstances such as high temperature, high pressure, reduce the external environment condition impact on conveying gas, applied widely, meet actually used needs.
Above content is to combine concrete preferred implementation further detailed description of the utility model; it cannot be assumed that of the present utility model being embodied as is confined to these explanations; for this utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
