It is well known that bellows be applied to urban construction, residential quarters ground water drainage, blow-off line, highway,
The irrigation conveying etc. of high-tension cable, harbour, oil, chemical industry, mine for the conveying of fluid and in the water of farmland, is applied especially to
Fuel gas transmission pipeline and artificial coal gas Natural Gas Conversion improvement project, bellows can fundamentally solve combustion gas metal and introduce pipe
Corrosion failure problem, but its inside pipe wall be smooth flat or existing defects.Combustion gas improvement project is to involve thousand ten thousand
Family engineering.Pipeline is needed replacing, is digged pit, stemming operation expends big, welding, destruction road
There are many bellows type currently on the market, but general action is in different industries, and are used as pre-buried water now
The bellows of electric bushing, since different regions acid-base property is different, geologic structure is different etc., factors cause the bellows longevity used
Life is not very long, if general bellows is destroyed, the internal water power pipeline corresponding service life can shorten, and general
Bellows, which is under pressure, to be easily damaged.
Utility model content
In view of the deficienciess of the prior art, the utility model aim is to provide a kind of PE composite multi-layers bellows, with solution
Certainly the problems mentioned above in the background art, the utility model is reasonable for structure, excellent shock resistance, and service life is long.
To achieve the goals above, the utility model is to realize by the following technical solutions：A kind of PE composite multi-layers
Bellows, including annular auxiliary tube, elastic rubber stick, outer layer pipe, protective layer, adhesive layer, barrier layer, aramid layer and interior
Layer pipeline has poured annular auxiliary tube on the tube wall of the outer layer pipe, and the inner cavity of the annular auxiliary tube is hollow and seals,
The section of the annular auxiliary tube is ellipse, and elastic rubber stick, the protective layer setting are uniformly set in the annular auxiliary tube
In outer layer pipe annular side, in protective layer annular side, the barrier layer is arranged in adhesive layer for the adhesive layer setting
Annular side, the aramid layer are mounted on barrier layer annular side, and the inner layer pipe is arranged in aramid layer inner ring
Shape side.
Further, the outer layer pipe is constituted with inner layer pipe polythene material.
Further, nitrogen is filled in the annular auxiliary tube.
Further, the protective layer is made of stainless steel.
Further, the adhesive layer is made of Thermoplastic adhesive.
Further, the barrier layer is made of poly- beta-lactam.
Further, the aramid layer is made of polyurethane material.
The beneficial effects of the utility model：A kind of PE composite multi-layers bellows of the utility model, because the utility model adds
Annular auxiliary tube, elastic rubber stick, the design has been added to keep outer layer pipe more flexible, increase the utility model uses the longevity
Life, because protective layer is made of stainless steel, will not be easily deformed as general pipeline since standing time is long,
Ensure when bellows is embedded in ground end, pipe shape is kept when being squeezed, the complete of internal hydroelectric facility is protected, because of polyamides
Amine layer is made of polyurethane material, further plays insulation effect, and polyurethane has certain self-healing, because of barrier
Layer is made of poly- beta-lactam, which effectively prevents the infiltration of fuel oil and evaporant, increases making for the utility model
With the service life, because adhesive layer is made of Thermoplastic adhesive, which increases the bonding stability of barrier layer and protective layer, this reality
Reasonable with new structure, excellent shock resistance, service life is long.
Description of the drawings
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other spies of the utility model
Sign, objects and advantages will become more apparent upon：
Fig. 1 is a kind of structural schematic diagram of PE composite multi-layers bellows of the utility model；
In figure：1- annulars auxiliary tube, 2- elastic rubbers stick, 3- outer layer pipes, 4- protective layers, 5- adhesive layers, 6- barrier layers,
7- aramid layers, 8- inner layer pipes.
Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of PE composite multi-layers bellows, including annular are auxiliary
Pipe 1, elastic rubber stick 2, outer layer pipe 3, protective layer 4, adhesive layer 5, barrier layer 6, aramid layer 7 and inner layer pipe 8 are helped, outside
Annular auxiliary tube 1 is poured on the tube wall of layer pipeline 3, the inner cavity of annular auxiliary tube 1 is hollow and seals, annular auxiliary tube 1
Section is ellipse, and elastic rubber stick 2 is uniformly set in annular auxiliary tube 1, and protective layer 4 is arranged in 3 annular side of outer layer pipe,
The setting of adhesive layer 5 is arranged in 4 annular side of protective layer, barrier layer 6 in 5 annular side of adhesive layer, and aramid layer 7 is mounted on
6 annular side of barrier layer, inner layer pipe 8 are arranged in 7 annular side of aramid layer.
Outer layer pipe 3 is constituted with 8 polythene material of inner layer pipe, and nitrogen is filled in annular auxiliary tube 1, and protective layer 4 is not
