A kind of plastic elbow, described elbow is by internal layer and is covered in the outer layer on internal layer surface and forms；The side of described internal layer and outer layer is provided with some protuberances and some grooves, and the top of described protuberance be hook-shaped make internal layer pass through this hook formation compact siro spinning technology with outer layer.Internal layer and outer layer tight union is may insure that, it is possible to prevent from the process of mixing solid-liquid object conveying, ensure that ectonexine will not fall off by this protuberance.
As a kind of preferred version, the number of described protuberance is two or more.
As a kind of preferred version, described protuberance is positioned at the middle part of internal layer and the side of outer layer.
As a kind of preferred version, described protuberance is distributed evenly in the side of internal layer and outer layer.
As a kind of preferred version, the number of described protuberance is two, is symmetrically distributed on internal layer.
As a kind of preferred version, the number of described groove is two.
As a kind of preferred version, described groove is symmetrically distributed in the both sides of a certain protuberance.
As a kind of preferred version, seamlessly transitting with the discontiguous side of outer layer of described internal layer, the internal diameter of described internal layer is identical with the diameter of tubing.May insure that identical with the diameter of tubing of the internal diameter of internal layer can seamlessly transit between elbow tubing.
As a kind of preferred version, described outer layer is common PE layer；Described internal layer is wear-resistant material layer.Described outer layer is referred to the design that conventional PE electric smelting is crucial.Described outer layer is for bearing the normal pressure of tubing.
As a kind of preferred version, described outer layer is common PE layer；Described internal layer is wear-resisting PE layer.
Compared with prior art, there is advantages that
The present invention, by the design to endothecium structure, makes energy compact siro spinning technology between ectonexine, it is ensured that internal layer will not depart from the process of mixing solid-liquid object conveying.The internal layer of described elbow adopts high-abrasive material, improves the wearability of elbow, the use of its bonded wear-resistant PE pipe, it is possible to substitutes Ceramo-steel pipe and is used for carrying solidliquid mixture.
