Abstract
The utility model discloses an elbow pipe joint whose both ends are provided with coupling flanges. The elbow joint is characterized in that the elbow joint is provided with an elbow pipe body which is made of rubber and provided with multi-layer cord plies, both ends of the elbow body are provided with the coupling flanges, the coupling flanges are made of metal and respectively sheathed on both ends of the elbow body, and the coupling flanges are provided with combination parts combined with the coupling flanges. The elbow pipe joint has the advantages of simple structure and convenient fabrication. Because the elbow pipe joint has definite flexibility, the elbow pipe joint is suitable for the upper displacement, lower displacement, left displacement, right displacement, and angle displacement of pipelines. The coupling flanges can rotate around an axis, so pipelines can be conveniently installed and maintained.
Description
The utility model is about pipe joint, particularly about having flexible elbow.
The frequent in the line use of metallic conduit has elbow.Because the various working medium of carrying in the pipeline all are under the certain working pressure, so the manufacturing of the also normal all employings of elbow metal.Because above-mentioned metal winding pipe joint is a rigid construction, amount of deformation is atomic little, so the physical dimension relation that pipeline is installed requires very tight.This not only influences the speed of construction, also means the increase of expense.And from now on dismounting maintenance brought many inconvenience.
The purpose of this utility model is to provide a kind of sufficient intensity that has, and certain flexible elbow is arranged again.
The purpose of this utility model is achieved in that there is the elbow of coupling flange at a kind of two ends, it is characterized in that being provided with the elbow body by the rubber manufacturing, that contain the multilayer hangings lay, that two ends are provided with coupling flange; Described coupling flange is enclosed within above-mentioned elbow body two ends by the metal manufacturing, and is provided with the anastomosis part that is harmonious with above-mentioned coupling flange.
Below in conjunction with accompanying drawing the utility model is done into the description in step down.
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is embodiment 2 structural representation.
Fig. 3,4,5 and 6 is the structural representation of elbow body and coupling flange bound fraction.
Embodiment 1: the utility model comprises coupling flange 2 and elbow body 5.Elbow body 5 is made by the rubber material that contains hangings lay 6.The diameter of bore of elbow body 5 is consistent.The number of plies of hangings lay 6 is by its working pressure of bearing size decision.The material of hangings lay 6 can be cotton thread, nylon wire or steel wire.The angle α of elbow body 5 two ends shaft axiss can be 90 °～175 °.The two ends of elbow body 5 respectively are provided with coupling flange 8.At least potted line 9, its peripheral edge portion of being provided with 2 circle projectioies on coupling flange 8 outer surfaces are provided with the bulge loop 10 that steel wire 7 is contained in inside.Coupling flange 2 is the ring of steel, and it is provided with some screws 1.Coupling flange 2 is enclosed within the two ends of elbow body 5 respectively, and its outer surface A is provided with circular groove 3 and annular projection 4.Above-mentioned circular groove 3 and annular projection 4 are still the bound fraction that the coupling flange 8 of coupling flange 2 and elbow body 5 is harmonious.Bulge loop 10 is embedded in the circular groove 3, and annular projection 4 then is entrenched in the groove between bulge loop 10 and elbow body 5 outer walls.
Embodiment 2: present embodiment comprises coupling flange 2 and elbow body 11.Elbow body 11 by the rubber material manufacturing contains hangings lay 6.The number of plies of hangings lay 6 is by its working pressure of bearing decision, and its material can be cotton thread, nylon wire or steel wire.Elbow body 11 middle aperture are greater than the aperture, two ends, and are the spheroid shape of a biasing.The angle α of elbow body 11 two ends shaft axiss can be 90 °～175 °.The two ends of elbow body 5 respectively are provided with coupling flange 8.At least be provided with the potted line 9 of 2 circle projectioies on coupling flange 8 outer surfaces, its peripheral edge portion then is provided with the bulge loop 10 that inside includes steel wire 7.Coupling flange 2 is the ring of steel, and it is provided with some screws 1.Coupling flange 2 is enclosed within the two ends of elbow body 5 respectively, and its outer surface A is provided with circular groove 3 and annular projection 4.Above-mentioned circular groove 3 and circular protrusion 4 have constituted the bound fraction that is harmonious with elbow body 11.
For adapting to different working pressures, the coupling flange 8 of elbow body can adopt different structural type with the bound fraction of coupling flange 2.Fig. 3 to Fig. 6 has shown the structural type of four kinds of different coupling flanges and bound fraction.Fig. 3 to Fig. 5 has shown that three kinds have the coupling flange 8 of bulge loop 10 and have the structural type of the coupling flange 2 of circular groove 3 and annular projection 4.Different between the top end face of the annular projection 4 of coupling flange 2 and the outer surface A, i.e. the height difference of annular projection 4 apart from a.Fig. 3 is the situation of a=0, and promptly annular projection 4 flushes with outer surface A.Fig. 4 is the situation of a＜0, and promptly annular projection 4 is lower than outer surface A.Fig. 5 then is the situation of a＞0, and promptly annular projection 4 is higher than outer surface A.Fig. 6 has shown the structural type that a kind of elbow body that is fit to low working pressure combines with coupling flange.The bound fraction that the transverse section of coupling flange 8 is rectangular, 2 of coupling flanges are provided with the rectangular annular breach 12 in transverse section.
The utility model is because the elbow body is a rubber product, has certain flexiblely, and the installation and maintenance of pipeline are brought great convenience.Coupling flange and elbow body are made respectively, not only help processing, and the screw contraposition when helping installing.In the pipeline of the utility model applicable to 0.6～1.5MPa working pressure.
