Abstract
The utility model discloses an elbow joint. The elbow joint comprises a joint body and connecting flanges which are arranged at the two ends of the joint body, the joint body is composed of a metal skeleton and rubber which is used for covering the metal skeleton, externally-turning protruding edges are arranged at the two ends of the joint body, the connecting flanges are made of metal and is tightly buckled with the externally-turning protruding edges. The elbow joint has the advantages of being simple in structure, and convenient to manufacture. Due to the fact that the elbow joint is manufactured by using the rubber to cover the metal skeleton, the elbow joint has sufficient rigidity as well as certain flexibility simultaneously, and is applicable to vertical and horizontal transposition of pipelines.
Description
Technical field
The utility model relates to a kind of pipe joint, relates in particular to a kind of elbow.
Background technique
Metallic conduit uses elbow in the line frequently, owing to the various working medium of carrying in the pipeline all are under the certain working pressure, so also normal all employings metal manufacturing of elbow.Because the elbow of this metal manufacturing is rigid construction, amount of deformation is extremely small, so the physical dimension relation that pipeline is installed requires very strict.This not only influences the speed of construction, also means the increase of expense, and dismounting maintenance is from now on brought many inconvenience.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of sufficient intensity that has, and has certain flexible elbow again.
The technical solution of the utility model is: a kind of elbow, the adpting flange that comprises joint body and joint body two ends, described joint body is made of the rubber of metal frame and coated metal skeleton, the two ends of joint body are provided with the convex edge of turning up, described adpting flange is made of metal, and closely fastens with above-mentioned convex edge.
As preferably, the internal diameter at described joint body middle part is greater than the internal diameter at two ends.
As preferably, the inside, termination of described joint body is embedded with ring and supports.
The beneficial effects of the utility model are: the utility model is simple in structure, easily manufactured, owing to adopt rubber coated metal skeleton to make, makes it when having sufficient intensity, has necessarily flexiblely again, can be fit to the displacement up and down of pipeline.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, joint body; 2, adpting flange; 11, rubber; 12, metal frame; 13, ring supports.
Embodiment
As a kind of mode of execution of the present utility model, as shown in Figure 1, a kind of elbow, the adpting flange 2 that comprises joint body 1 and joint body 1 two ends, described joint body 1 is made of the rubber 11 of metal frame 12 and coated metal skeleton 12, the two ends of joint body 1 are provided with the convex edge of turning up, and described adpting flange 2 is made of metal, and closely fasten with above-mentioned convex edge.As preferably, the internal diameter at described joint body 1 middle part is greater than the internal diameter at two ends, and the inside, termination of described joint body 1 is embedded with ring and supports 13.
The utility model is simple in structure, easily manufactured owing to adopt rubber 11 coated metal skeletons 12 to make, be its when having sufficient intensity, have necessarily flexiblely again, can be fit to the displacement up and down of pipeline.
