Abstract
The utility model discloses a reducing elbow joint. The reducing elbow joint comprises an L-shaped pipe body composed of a first plug-in pipe and a second plug-in pipe which are communicated with each other; the inside diameter of the first plug-in pipe is larger than that of the second plug-in pipe; the pipe thickness of the first plug-in pipe is the same as that of the second plug-in pipe; a first groove is formed in the first plug-in pipe; a seal ring with an N-shaped cross section is embedded into the first groove; a first annular groove and a second annular groove are respectively formed in two sides of the seal ring; a second groove is formed in the second plug-in pipe; an O-shaped ring is embedded into the second groove. The reducing elbow joint is firm in connection, good in air tightness, convenient to assemble, and relatively low in production cost.
Description
Technical field
The utility model relates to the pipe joint technical field, especially relates to a kind of reducing elbow.
Background technique
Pipe joint is the connecting element between pipeline, it is tight and firm for pipeline is connected, general hinge screw thread or the groove opened in the end of pipe joint, in order to be connected with pipeline thread or groove, existing pipe joint connects firm not, and sealing is poor, and the pipeline that can not be applicable to high-pressure liquid connects, and assembling is inconvenient, cost of production is higher.
Summary of the invention
The deficiency existed for above-mentioned prior art, the purpose of this utility model will provide a kind of and be connected firmly, the reducing elbow of good airproof performance, and it is easy to assembly, and cost of production is lower.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of reducing elbow, comprise " L " shape pipeline body formed by the first insertion pipe and the second insertion pipe, the first insertion pipe and the second insertion pipe are interconnected, the internal diameter of described the first insertion pipe is greater than the internal diameter of described the second insertion pipe, described the first insertion pipe is identical with the pipe thickness of described the second insertion pipe, described the first insertion pipe is provided with the first groove, be embedded with the seal ring that cross section is " N " shape in described the first groove, the both sides of described seal ring are respectively equipped with the first circular groove and the second circular groove, described the second insertion pipe is provided with the second groove, be embedded with round section joint ring in described the second groove.
Wherein, on described the first insertion pipe and described the second insertion pipe, be respectively equipped with some helical teeth rings, the external diameter of described helical teeth ring is reduced outward gradually by inner end.The true dip direction of the outside hypotenuse of described seal ring is consistent with the true dip direction of described helical teeth ring.Described the first circular groove becomes " V " shape with the cross section of described the second circular groove.The corner joint, the outside of described the first insertion pipe and the second insertion pipe is provided with lead angle.
After adopting technique scheme, the advantage that compared to the prior art the utility model had is:
Reducing elbow described in the utility model, the first insertion pipe offers the first groove, be embedded with the seal ring that cross section is " N " shape in the first groove, the both sides of seal ring are respectively equipped with the first circular groove and the second circular groove, outer end be the first circular groove, by inner end is the second circular groove, when the first insertion pipe is inserted in pipeline, the inwall of pipeline pushes described seal ring, seal ring lateral extrusion power and axial friction, make the second circular groove of described seal ring inwardly close up, the first circular groove of described seal ring a little outwards opens, it is connected firmly, good airproof performance.Described the second insertion pipe is provided with the second groove, in described the second groove, is embedded with round section joint ring, and when the second insertion pipe is inserted in pipeline, round section joint ring plays the effect of being tightly connected, easy to assembly, and cost of production is lower.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1: structural representation of the present utility model.
Fig. 2 is the local structure for amplifying schematic diagram in A place in Fig. 1.
In figure, 1: the first insertion pipe; 2: the second insertion pipes; 3: seal ring; 4: the first circular grooves; 5: the second circular grooves; 6: the helical teeth ring; 7: round section joint ring; 8: the first grooves; 9: the second grooves.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see shown in Fig. 1 to Fig. 2: a kind of reducing elbow, comprise " L " shape pipeline body formed by the first insertion pipe 1 and the second insertion pipe 2, the first insertion pipe 1 and the second insertion pipe 2 are interconnected, the internal diameter of described the first insertion pipe 1 is greater than the internal diameter of described the second insertion pipe 2, described the first insertion pipe 1 is identical with the pipe thickness of described the second insertion pipe 2, described the first insertion pipe 1 is provided with the first groove 8, be embedded with the seal ring 3 that cross section is " N " shape in described the first groove 8, the both sides of described seal ring 3 are respectively equipped with the first circular groove 4 and the second circular groove 5, outer end be the first circular groove 4, by inner end is the second circular groove 5, when the first insertion pipe 1 is inserted in pipeline, the inwall of pipeline pushes described seal ring 3, seal ring 3 lateral extrusion power and axial frictions, make the second circular groove 5 of described seal ring 3 inwardly close up, the first circular groove 4 of described seal ring 3 a little outwards opens, it is connected firmly, good airproof performance.Described the second insertion pipe 2 is provided with the second groove 9, in described the second groove 9, is embedded with round section joint ring 7, and when the second insertion pipe 2 is inserted in pipeline, round section joint ring 7 plays the effect of being tightly connected, easy to assembly, and cost of production is lower.Wherein, on described the first insertion pipe 1 and described the second insertion pipe 2, be respectively equipped with some helical teeth rings 6, the external diameter of described helical teeth ring 6 is reduced outward gradually by inner end.The true dip direction of the outside hypotenuse of described seal ring 3 is consistent with the true dip direction of described helical teeth ring 6.Described the first circular groove 4 becomes " V " shape with the cross section of described the second circular groove 5.The corner joint, the outside of described the first insertion pipe 1 and the second insertion pipe 2 is provided with lead angle.
