Description
Technical field
The utility model relates to Bellows Technology field more particularly to a kind of high rigidity steel band bellows.
Background technique
Existing plastic corrugated pipe is a kind of plastic extruding forming, and a kind of plastics-production can not be in view of that should guarantee to draw
It stretches intensity, elasticity modulus, ring stiffness and considers tubing flexibility again.Therefore manufacturer is much of poor quality when carrying storage
Product be easy compressive strain, the compressive strain on vehicle among factory transport, workers carry does not pay attention to being easy to touch rotten.In project installation mistake
Do not pay attention to being easy to smash tubing when backfilling the cubic metre of earth and stone in journey, since over and around compressive load acts on after installation, tubing
Deformation is unbearably born, or is inwardly squeezed, causes pumped (conveying) medium in pipe to leak, causes soil secondary pollution, since fluid media (medium) seeps
Leakage outflow, slowly corrodes embankment around tubing, makes embankment inanition around tubing that the earthwork be caused to can't bear the heavy load, therefore often occur
Road house collapse car crash accident.
Due to above, urgent need develops a kind of high intensity composite pipes and not only can guarantee pipe ring stiffness but also can guarantee
Tubing flexibility improves the safety of pipeline.
Utility model content
Purpose of the utility model is to solve bellows exists in the prior art to occur deforming vulnerable to extruding or damaged
The shortcomings that, and a kind of high rigidity steel band bellows proposed.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of high rigidity steel band bellows, including tube body are designed, are fold section in the middle part of the tube body, the tube body both ends are
Smooth section, the fold section outside is equipped with sheath, and the tube body includes base, and base's appearance is equipped with flame-retardant layer, the resistance
It fires layer appearance and is equipped with wearing layer, the inboard wall of tube body is equipped with erosion resistant coating, and the sheath includes protective layer and steel band, and the steel band is
Ring steel belt, and the section of steel band be it is arc-shaped, the steel band is set on the outside of the lug boss of fold section, the protection layer number
It is two layers, and two layers of protective layer is wrapped in inside and outside steel band.
Preferably, the wearing layer is polytetrafluorethylecoatings coatings.
Preferably, the flame-retardant layer is polyvinyl chloride flame retardant coating.
Preferably, the erosion resistant coating is novolac epoxy resin coating.
Preferably, protrusion is equipped on the outside of the erosion resistant coating, the raised annular is set to smooth section of outside of tube body.
Preferably, the base and protective layer are all made of polythene material and are made.
Preferably, it is bonded between the steel band and protective layer by adhering resin.
The utility model proposes a kind of high rigidity steel band bellows, beneficial effect is: the bellows structure is simple, real
With conveniently, there is good high rigidity, by increasing sheath in fold section lug boss, be that bellows promotes intensity by steel band, avoid
The case where bellows is deformed because of compression, meanwhile, which is coated with wearing layer, flame-retardant layer and anti-corrosion
Layer, can effectively extend the physical life of bellows.
