Abstract
The utility model relates to the technical field of pipes, in particular to a novel inner-layer pipe fitting. The novel inner-layer pipe fitting is characterized by comprising a pipe fitting, a small pipe, a hollow pipe layer and an inner pipe layer, the inner pipe layer is arranged at the inner side of the pipe fitting, the pipe fitting and the inner pipe layer are formed by drawing the same materials for a time, no welding is needed, the operation is convenient, the pipe pressure is improved, and breakage is prevented.
Description
Technical field
The utility model relates to the pipe technology field, especially a kind of novel internal layer pipe fitting.
Background technique
The transition of the different bore diameters of its big small pipeline of tradition pipe fitting often need be welded heavy caliber pipe fitting and small-bore pipeline, not only usually wastes time and energy, and often causes fracture easily, and pipeline was lost efficacy.
Summary of the invention
For addressing the above problem; The utility model provides a kind of novel internal layer pipe fitting, and said a kind of novel internal layer pipe fitting is characterized in that; Comprise: pipe fitting 1, tubule 2, pipe voided layer 3, inner tube layer 4; Said a kind of novel internal layer pipe fitting is provided with inner tube layer 4 in pipe fitting 1 inboard, and its pipe fitting 1 is the moulding of same material one-off drawing with inner tube layer 4.
The utility model effect: 1. one-off drawing moulding need not welding; 2. easy-to-operat; 3. the raising pipeline pressure prevents fracture.
Description of drawings
Fig. 1 is the utility model schematic representation;
Wherein: pipe fitting 1, tubule 2, pipe voided layer 3, inner tube layer 4.
Embodiment
As shown in the figure, said a kind of novel internal layer pipe fitting is provided with inner tube layer 4 in pipe fitting 1 inboard, holds the equipment drawing die earlier successfully, and its pipe fitting 1 is same materials with inner tube layer 4, drawing and forming once on drawing die equipment.
Claims (1)
1. a novel internal layer pipe fitting is characterized in that, comprising: pipe fitting, tubule, pipe voided layer, inner tube layer, and said a kind of novel internal layer pipe fitting is provided with inner tube layer in the pipe fitting inboard, and its pipe fitting and inner tube layer are the moulding of same material one-off drawing.
