Abstract
The utility model discloses a tee pipe coupling with an inner threaded bushing. The tee pipe coupling with the inner threaded bushing comprises a T-shaped pipeline body, wherein the pipeline body is provided with three connector pipes which are communicated with one another; the three connector pipes are respectively provided with an inner threaded bushing; the inner pipe surface of each inner thread bushing is provided with a threaded connecting part; each connector pipe is provided with a first groove and a second groove, the first groove is arranged on the outer end of the second groove, a seal ring with an N-shaped cross section is embedded inside the first groove, and two sides of the seal ring are respectively provided with a first annular groove and a second annular groove; the inner threaded bushings are clamped inside the second grooves in a rotating manner; the inner end of each second groove is provided with a convex ring which abuts against the corresponding inner threaded bushing. The tee pipe coupling is firm in connection, good in sealing performance, convenient to assemble and low in production cost.
Description
Technical field
The utility model relates to pipe joint technical field, especially relates to a kind of three-way union with inner tooth sleeve pipe.
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, 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 existing for above-mentioned prior art, the purpose of this utility model will provide a kind of and be connected firmly, the three-way union with inner tooth sleeve pipe 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 three-way union with inner tooth sleeve pipe, comprise "T"-shaped pipeline body, described pipeline body is provided with three joint intubate that are interconnected, in three described joint intubate, be respectively equipped with inner tooth sleeve pipe, the inner tube surface of described inner tooth sleeve pipe is provided with threaded joints, described joint intubate is provided with the first groove and the second groove, the first groove is located at the outer end of the second groove, in described the first groove, be embedded with the seal ring that cross section is " N " shape, the both sides of described seal ring are respectively equipped with the first circular groove and the second circular groove, described inner tooth sleeve pipe is arranged in described the second groove rotationally, the inner end of described the second groove is provided with the bulge loop offseting with described inner tooth sleeve pipe.
Wherein, described joint intubate is provided with some helical teeth rings, and 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.The both sides of described seal ring are respectively equipped with the circular groove that cross section becomes " V " shape.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
Three-way union with inner tooth sleeve pipe described in the utility model, its joint intubate is provided with groove, in groove, be embedded with the seal ring that cross section is " N " shape, the both sides that this cross section is the seal ring of " N " shape are respectively equipped with circular groove, what be abutted against an intubate outer end is the first circular groove, what be abutted against an intubate inner end is the second circular groove, when joint intubate is inserted in pipeline, the inwall of pipeline pushes described seal ring, seal ring lateral extrusion power and axial friction, the second circular groove of described seal ring is inwardly closed up, the first circular groove of described seal ring a little outwards opens, device for cleaning pipeline is crossed inner tooth sleeve pipe and is firmly connected with joint intubate, it is connected firmly, good airproof performance, and easy to assembly, cost of production is lower.
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: joint intubate; 2: the first grooves; 3: seal ring; 4: the first circular grooves; 5: the second circular grooves; 6: helical teeth ring; 7: the second grooves; 8: inner tooth sleeve pipe; 9 bulge loops; 10: threaded joints.
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 three-way union with inner tooth sleeve pipe, comprise "T"-shaped pipeline body, described pipeline body is provided with three joint intubate 1 that are interconnected, in three described joint intubate 1, be respectively equipped with inner tooth sleeve pipe 8, the inner tube surface of described inner tooth sleeve pipe 8 is provided with threaded joints 10, joint intubate 1 is provided with the first groove 2 and the second groove 7, the first groove 2 is located at the outer end of the second groove 7, in the first groove 2, be embedded with the seal ring 3 that cross section is " N " shape, the both sides of described seal ring 3 are respectively equipped with the circular groove that cross section becomes " V " shape, what be abutted against an intubate 1 outer end is the first circular groove 4, what be abutted against an intubate 1 inner end is the second circular groove 5, described inner tooth sleeve pipe 8 is arranged in described the second groove 7 rotationally, inner tooth sleeve pipe 8 can be in the interior rotation of the second groove 7, when spigot joint 1 inserts in pipeline, the threaded joints 10 of inner tooth sleeve pipe 8 can be spirally connected with pipeline easily, inner tooth sleeve pipe 8 and seal ring 3 fitted seal better effects if, the inner end of described the second groove 7 is provided with the bulge loop 9 offseting with described inner tooth sleeve pipe 8, 9 pairs of inner tooth sleeve pipes 8 of bulge loop play fixed support effect, described joint intubate 1 is provided with some helical teeth rings 6, the external diameter of helical teeth ring 6 is reduced outward gradually by inner end.The true dip direction of the outside hypotenuse of seal ring 3 is consistent with the true dip direction of helical teeth ring 6.
Adopt the three-way union with inner tooth sleeve pipe of technique scheme, when joint intubate 1 is inserted in pipeline, the inwall of pipeline pushes described seal ring 3, seal ring 3 lateral extrusion power and axial frictions, inwardly close up the second circular groove 5 of described seal ring 3, and the first circular groove 4 of described seal ring 3 a little outwards opens, device for cleaning pipeline is crossed inner tooth sleeve pipe 8 and is firmly connected with joint intubate 1, it is connected firmly, good airproof performance, and easy to assembly, and cost of production is lower.
