Abstract
The utility model relates to the technical field of pipelines, and in particular relates to a novel elbow. The novel elbow is characterized by comprising a hollow pipe, an outer pipe wall, an upper-pipe layer head, a pipe inner layer and a lower-pipe layer head, wherein the hollow pipe is provided with the lower-pipe layer head, and the hollow pipe and the lower-pipe layer head are made of same materials and are stretched and molded by one time. The novel elbow has the beneficial effects that the welding is not needed, the operation is convenient, the pipeline pressure is improved and the fracture is prevented.
Description
Technical field
The utility model relates to the pipe technology field, especially a kind of novel elbow.
Background technique
The transition of the different bore diameters of its large small pipeline of tradition pipe fitting often needs large-caliber pipe fittings and small-bore pipeline are welded, and not only usually wastes time and energy, and often easily causes fracture, makes pipeline failure.
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel elbow, described a kind of novel elbow, it is characterized in that, comprise: hollow tubular 1, outer tube wall 2, upper pipe layer 3, inner tube layer 4, lower pipe layer 5, described a kind of novel evacuated elbow is provided with lower pipe layer 5 at hollow tubular 1, and its hollow tubular 1 and lower pipe layer 5 is the moulding of same material one-off drawing.
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 diagram;
Wherein: hollow tubular 1, outer tube wall 2, upper pipe layer 3, inner tube layer 4, lower pipe layer 5.
Embodiment
As shown in the figure, described a kind of novel elbow is provided with lower pipe layer 5 at hollow tubular 1, and its hollow tubular 1 and lower pipe layer 5 is same materials, drawing and forming once on drawing die equipment.
Claims (1)
1. a novel elbow is characterized in that, comprising: hollow tubular, outer tube wall, upper pipe layer head, inner tube layer, lower pipe layer head, and described a kind of novel elbow is provided with lower pipe layer head at hollow tubular, and its hollow tubular and lower pipe layer head are the moulding of same material one-off drawing.
