Description
Technical field
The present invention relates to the vehicle-mounted bottle fields of liquefied natural gas, and in particular to a kind of big volume vehicle-mounted bottle interlayer heat insulation structural twines
Winding method.
Background technique
In recent years, as country carries forward vigorously efforts at environmental protection and natural gas extraction, transport and related auxiliary facility development
Constantly improve, vehicle liquefied natural gas gas cylinder is because having both the advantages such as energy conservation and environmental protection, course continuation mileage length, reliability height, in market
Upper demand surges.Especially " heavy-duty diesel vehicle pollutant emission limit and measurement method (Chinese 6th stage) " will be from 2019
Implement from July 1, for liquefied natural gas as a kind of significant new energy substitute of environment-friendly advantage, demand can also be anxious at that time
Play rises, while its storage container --- the demand of mounted gas cylinder can also rise with it.
The liner of LNG vehicle-mounted bottle contains natural gas liquids, and at -162 DEG C or so, the outer gallbladder of LNG vehicle-mounted bottle exposes temperature
Temperature is between -10 DEG C~40 DEG C at normal temperature, and internal-external temperature difference is between 152 DEG C~202 DEG C.Its interlayer is using high vacuum
Multistory steel structure, vehicle-mounted bottle liner wind laminated aluminium foil+glass fibre composite insulation material after through inner-outer tube suit, welding,
Interlayer helium leak test the multiple working procedures such as vacuumizes and controls layer vacuum in 2*10-2Pa is hereinafter, achieve the effect that insulation.
But conventional interlayer heat insulation structural both ends end socket is heat-insulated using end socket package piece structure, package piece complex manufacturing technology, wrapping are multiple
It is miscellaneous, the quality of production is difficult to control, simultaneously because the cover width of some big volume vehicle-mounted bottle cylinder longer dimensions, heat-insulating material need to reach
To 2m or more, and it is limited to the production ability (aluminium foil industry is most wide to be fabricated into 1.8m wide for aluminium foil) of aluminium foil industry, removed
Two end socket of front and back need to be heat-insulated outer with end socket package piece, and cylinder need to overlapped that mode is wound with the composite insulation materials of volume two, winding
Complex process, low efficiency, at high cost, overlap joint quantity is more and amount of lap is difficult to control.Therefore explore it is a kind of efficiently, simple process it is easily real
The interlayer heat insulation structural winding method that existing, low in cost, quality easily guarantees is those skilled in the art's urgent problem to be solved.
Summary of the invention
For complex process present in existing vehicle-mounted bottle interlayer heat insulation structural winding process, low efficiency, at high cost
Problem, the present invention provides a kind of big volume vehicle-mounted bottle interlayer heat insulation structural winding methods.
The following technical solution is employed by the present invention:
A kind of big volume vehicle-mounted bottle interlayer heat insulation structural winding method winds a roll of composite adiabatic on the liner of vehicle-mounted bottle
Material, composite insulation material are combined by one layer of aluminium foil and layer of glass paper, winding method the following steps are included:
Step 1: winding 30 layers of liner, after having wound using an entire volume composite insulation material, the composite adiabatic material of innermost layer
Material cannot be contacted with outermost composite insulation material；
Step 2: the both ends of the composite insulation material wound will grow two ends of liner, the composite adiabatic that will be grown
The end of material is folded to the end of liner；
Folding process specifically: first fold the end of the right inward gallbladder of the end of composite insulation material, then will be compound
The left side of the end of heat-insulating material is folded to the end of liner；
Then the end of the front inward gallbladder of the end of composite insulation material is folded, then by the end of composite insulation material
Rear inward gallbladder end fold；
Step 3: after folding, will be fixed at folding with aluminum foil and adhesive tape.
Preferably, in step 1,30 layers of liner are wound specifically: 15 layers are first wound, then cuts off composite insulation material,
15 layers are wound again.
The invention has the advantages that:
Not only manufacture craft is simple for this method, but also low in cost, it is often more important that has fully phased out end socket package piece, has reduced
2-3 heat-insulating material lap joint, when winding, are not necessarily to manual control amount of lap, and efficiency and quality obtained the promotion of matter.

Specific embodiment
A specific embodiment of the invention is described further in the following with reference to the drawings and specific embodiments:
In conjunction with Fig. 1 to Fig. 9, a kind of big volume vehicle-mounted bottle interlayer heat insulation structural winding method twines on the liner 1 of vehicle-mounted bottle
Around a roll of composite insulation material 2, composite insulation material is combined by one layer of aluminium foil and layer of glass paper, aluminium foil and glass
The all fire proofings of fibrous paper.In order to increase the width of composite insulation material, when production, two width aluminium foils can be overlapped, in this way
The composite insulation material breadth is most wide to can reach 2800mm, is adapted to the winding of the vehicle-mounted bottle of most of liquefied natural gas.
Winding method the following steps are included:
Step 1: winding 30 layers of liner, after having wound using an entire volume composite insulation material, the composite adiabatic material of innermost layer
Material cannot be contacted with outermost composite insulation material, ensure that heat insulation.
30 layers of liner of winding specifically: first wind 15 layers, then cut off composite insulation material, then wind 15 layers.
Step 2: the both ends of the composite insulation material wound will grow two ends of liner, specifically that can cover completely
Subject to lid liner, the end of the composite insulation material grown is folded to the end of liner.
Folding process specifically: first fold on the right side 3 of the end of composite insulation material to the end of liner, this is first
Secondary folding, as shown in Figures 2 and 3；
The left side 4 of the end of composite insulation material is folded to the end of liner again, this is second fold, such as Fig. 4 and
Shown in Fig. 5.
Then the front side 5 of the end of composite insulation material is folded to the end of liner, this is that third time folds, such as Fig. 6
With shown in Fig. 7；
The rear side 6 of the end of composite insulation material is folded to the end of liner again, this is the 4th folding, such as Fig. 8 and
Shown in Fig. 9.
Step 3: after folding, will be fixed at folding with aluminum foil and adhesive tape.
In above-mentioned folding process, the relaxation at folding is kept as far as possible, favorably gas therebetween is extracted.
Certainly, the above description is not a limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the technical staff in domain is made within the essential scope of the present invention also should belong to of the invention
Protection scope.
