Description

Technical Field

[0001] The utility model relates to the technical field of pipe connection, in particular to a pipeline connector. Background Art

[0002] As the basic infrastructure for fluid transmission, pipelines are widely used in water supply, drainage, oil and gas transportation, chemical production and other industries. With the acceleration of industrialization and the expansion of engineering scale, higher requirements are placed on the installation efficiency, sealing performance and long-term stability of pipeline systems. Although traditional pipeline connection methods, such as welding and threaded connections, meet basic connection requirements to a certain extent, they have gradually exposed many shortcomings in actual applications, such as high construction complexity, easy leakage, and difficult maintenance.

[0003] Based on the above problems, we have previously proposed a pipe connection assembly and a quick-install pipe connection structure (CN215111109U). In this technical solution, when using a pipe joint to connect the pipe, four screws and a combined cover ring are used. Although this structure ensures the stability of the connection to a certain extent, in actual operation, the disassembly process is quite cumbersome. Specifically, in order to remove the sealing ring or other sealing elements inside the pipe joint, the operator needs to loosen and remove the four screws one by one, and then disassemble the combined cover ring (usually composed of a first half cover and a second half cover) to perform necessary maintenance or replacement work. This process is not only time-consuming and labor-intensive, but may also cause damage to the sealing elements or damage to the connection parts due to improper operation, thereby affecting the sealing performance and operational safety of the entire pipeline system.

[0004] Therefore, in view of the above-mentioned problems existing in the prior art, it is necessary to improve and innovate the pipe connection assembly and the quick-install pipe connection structure to simplify the disassembly process, improve the operational convenience, and at the same time ensure the stability and sealing of the connection. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pipeline connector to solve the problems raised by the above-mentioned background technology.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a pipeline connector, comprising:

[0007] The pipe joint is a hollow structure, and a sealing adapter groove is reserved inside the hollow structure;

[0008] A sealing ring, wherein the sealing ring is installed inside the sealing adapter groove, and the outside of the sealing ring is a conical surface;

[0009] A pipeline, wherein the pipeline is inserted into the interior of the sealing ring and the exterior of the pipeline is connected with a convex ring;

[0010] A split gasket, which is installed on the outside of the pipeline, and the adjacent ends of the sealing ring and the split gasket are adapted to the convex ring and abut against the two sides of the convex ring respectively;

[0011] The gear ring nut is threadedly connected to the outside of the pipe joint, and the gear ring nut and the split washer are butted against each other through an inclined surface.

[0012] Furthermore, the diameters of both ends of the pipe joint are larger than the middle diameter, external threads are provided on the outer sides of both ends, and internal threads are provided on the inner side of the gear ring nut. The gear ring nut is connected and fixed to the pipe joint by the thread engagement of the external thread and the internal thread.

[0013] Furthermore, a plurality of circumferentially distributed protrusions are integrally connected to the middle portion of the pipe joint and the outside of the gear ring nut.

[0014] Furthermore, the sealing ring is adapted to the shape of the sealing adapting groove, and the conical surface of the sealing ring is fitted to the conical surface of the sealing adapting groove.

[0015] Furthermore, the inner sides of the adjacent ends of the sealing ring and the split gasket are both configured as arc surfaces, and the two arc surfaces are adapted to the convex curvature of the convex ring.

[0016] Furthermore, the end of the gear ring nut is arranged as a necking structure, and the necking structure and the sealing adapter groove can jointly constrain the sealing ring and the split gasket.

[0017] Furthermore, the split gasket includes a first gasket and a second gasket, and both ends of the first gasket and the second gasket are respectively provided with a positioning column and a positioning groove. When the first gasket and the second gasket are spliced, the positioning column is inserted into the inside of the positioning groove.

[0018] The utility model provides a pipeline connector. Compared with the prior art, it has the following beneficial effects:

[0019] The pipe connector improves the original structure by changing the original structure of connecting the pipe joint and the pipe with four screws and a combined cover ring into a structure of connecting internal and external threaded pipes. In this way, only a pipe clamp is needed for disassembly and assembly, which is convenient and quick, and the sealing structure will not be damaged due to improper operation.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a pipe connector, which consists of a pipe joint 1, two sealing rings 2, two pipes 3, two sets of split washers 4 and two toothed ring nuts 5, wherein the outer surfaces of the sealing rings 2 are all set to be conical surfaces, and the inner wall of the pipe joint 1 is reserved with a sealing adapter groove 12. When installing, the sealing ring 2 is installed inside the sealing ring adapter groove 12. Since the sealing ring adapter groove 12 and the sealing ring 2 are both conical, the sealing effect can be improved. The pipe 3 is inserted into the inside of the pipe joint 1, the sealing ring 2 is sleeved on the outside of the pipe 3, and then the split washer 4 is sleeved on the outside of the pipe 3. It should be noted that the surface of the pipe 3 is connected with a convex ring 31, and the sealing ring 2 and the split gasket 4 are respectively located on both sides of the convex ring 31. Finally, after the toothed ring nut 5 is sleeved on the outside of the pipe 3, the pipe 5 can be tightened on the outside of the pipe joint 1 by clamping the convex part 13 with tools such as pipe clamps, relying on the internal thread 51 of the toothed ring nut 5 and the external thread of the pipe joint 1. After tightening, the shrinkage of the toothed ring nut 5 will push the split gasket 4, and the conical surfaces of the sealing ring 2 and the sealing adapter groove 12 will also abut against each other, thereby giving two axial and opposite forces to the convex ring 31 at the same time, so that the pipe 3 is fixed inside the pipe joint 1.

[0027] It should be noted that the split gasket 4 includes two identical first gaskets 41 and a second hoop gasket 42. When the split gasket 4 is sleeved on the outside of the pipe 3, the first gasket 41 and the second gasket 42 are spliced ​​together, and the first gasket 41 and the second gasket 42 are constrained and limited by the positioning columns 43 and the positioning grooves 44 respectively arranged at both ends of the first gasket 41 and the second gasket 42.

[0028] During maintenance, it is only necessary to use a pipe clamp to disassemble the toothed ring nut 5 and withdraw it to a certain space distance, and then the split gasket 4 can be taken out from the pipeline, so that the pipe joint 1 and the sealing ring 2 can be disassembled from the entire pipeline system to achieve the purpose of replacement and cleaning.
