Technical Field

The utility model relates to the technical field of ferrule joints, in particular to a pipeline flexible ferrule joint.

Background Art

The ferrule joint is a new type of pipe connection element, and its structural forms usually include single ferrule structure and double ferrule structure. The single ferrule joint consists of the joint body, ferrule and compression nut. Compared with the double ferrule structure, it has a simpler structure, is easier to manufacture and install, and has a lower cost. However, during its use, an annular cutting edge at the front end of the ferrule is used to squeeze and contact the ferrule tube, so its sealing and pressure bearing performance are limited. In addition, there is generally only one sealing ring between the ferrule and the pipe, and the sealing effect is not very good. In some occasions where the pipeline pressure is high and the sealing requirements are high, its connection reliability is not easy to guarantee, and leakage is prone to occur in actual use.

In addition, the conventional ferrule joint uses conical surfaces to cooperate with each other to achieve a fixed connection, but the conical surfaces are complicated to process and the sealing effect is poor when they cooperate with each other.

DETAILED DESCRIPTION

The present invention will now be discussed with reference to exemplary embodiments. It should be understood that the embodiments discussed are only intended to enable those skilled in the art to better understand and implement the present invention, rather than to imply any limitation on the scope of the present invention.

As used herein, the term “including” and variations thereof are to be interpreted as open-ended terms meaning “including, but not limited to.” The term “based on” is to be interpreted as “based, at least in part, on.” The terms “one embodiment” and “an embodiment” are to be interpreted as “at least one embodiment.”

FIG1 schematically shows a cross-sectional view of a pipe union ferrule joint according to an embodiment of the present invention, and FIG2 schematically shows a stereoscopic view of a pipe union ferrule joint according to an embodiment of the present invention. As shown in FIGS. 1 and 2, a pipe union ferrule joint according to the present invention comprises:

The ferrule joint 10 is sleeved on the side wall of the first pipe 40, and one end of the ferrule joint 10 has a first protrusion 101, and the first protrusion 101 extends in a direction away from the first pipe 40;

The ferrule fixing seat 20 is sleeved on the side wall of the second pipe 50. One end of the ferrule fixing seat 20 has a connecting seat 201, and the connecting seat 201 extends in a direction away from the second pipe 50.

The connecting seat 201 is provided with a first groove 2011, the first protrusion 101 matches the outer contour shape of the first groove 2011, and the first protrusion 101 is inserted into the first groove 2011 to connect the first pipe 40 with the second pipe 50;

The two ends of the ferrule nut 30 are respectively sleeved on the ferrule pipe joint 10 and the ferrule fixing seat 20 to limit the first protrusion 101 to move in a direction away from the first groove 2011.

Specifically, the ferrule pipe joint 10 is welded to the side wall of the first pipe 40, and the ferrule fixing seat 20 is welded to the side wall of the second pipe 50, so as to achieve fixed connection respectively.

When the first pipe 40 and the second pipe 50 are connected, the first protrusion 101 is inserted into the first groove 2011, so that the first protrusion 101 and the first groove 2011 cooperate with each other to achieve a sealed connection. At this time, the ferrule nut 30 is inserted into the outside of the ferrule pipe joint 10 and the ferrule fixing seat 20. As the ferrule nut 30 is tightened, one end of the ferrule nut 30 gradually approaches the first protrusion 101 and presses the first protrusion 101 in the direction close to the first groove 2011, thereby limiting the first protrusion 101 and putting it in a tightened state, achieving a fixing and sealing effect, thereby completing the connection between the two pipes.

Furthermore, a limiting groove 301 is provided at one end of the ferrule nut 30, the limiting groove 301 matches the outer contour shape of the first protrusion 101, and the limiting groove 301 and the first groove 2011 surround the first protrusion 101;

The other end of the ferrule nut 30 is threadedly connected to the connecting seat 201 .

Specifically, when the ferrule nut 30 is installed, it is tightened with the connecting seat 201 from the end of the first pipe 40 to the direction close to the second pipe 50 until the limiting groove 301 squeezes the first protrusion 101 and cannot move, thereby completing the installation and achieving a sealed connection between the two pipes.

Furthermore, a second groove 2012 is provided on a side wall of the first groove 2011 facing the first protrusion 101 , and a first sealing ring 60 is provided in the second groove 2012 .

A third groove 102 is provided on the side wall of the first protrusion 101 facing the limiting groove 301 , and a second sealing ring 70 is provided in the third groove 102 .

Through the above-mentioned arrangement, when the first protrusion 101 is squeezed by the limiting groove 301 in the direction close to the first groove 2011, the first sealing ring 60 and the second sealing ring 70 between the first protrusion 101 and the first groove 2011, and between the first protrusion 101 and the limiting groove 301 can be squeezed, so as to achieve a better sealing effect. At the same time, the arrangement of the two sealing rings can respectively seal the path between the first pipe 40 and the first protrusion 101 and the limiting groove 301, and the path between the second pipe 50 and the first protrusion 101 and the first groove 2011, thereby achieving double sealing on the channels between the two pipes and the outside world.

Furthermore, the circumferential side wall of the first protrusion 101 is configured as a flat surface. Compared with the conventional conical surface, such a configuration makes processing easier. At the same time, the flat surface has a better matching effect and a better sealing effect than the conical surface.

Furthermore, a through hole 2013 is provided at the center of the connecting seat 201, and the diameter of the through hole 2013 is consistent with the diameter of the second pipe 50. When the ferrule fixing seat 20 is sleeved on the second pipe 50, the connecting seat 201 end extends out and cooperates with the first protrusion 101 to connect. At this time, there is a certain distance between the second pipe 50 and the first pipe 40, and communication cannot be achieved. A through hole 2013 with the same diameter as the second pipe 50 is provided in the connecting seat 201, so that the second pipe 50 can be further connected with the first pipe 40 through the through hole 2013.

Furthermore, the device of the utility model can be applicable to the scenario where the first pipeline 40 and the second pipeline 50 have the same diameter, and can also be applicable to the scenario where the first pipeline 40 and the second pipeline 50 have different diameters, and can fully realize the diameter change, extension, branching or turning of the pipeline.

In summary, the device of the utility model realizes the connection between the two pipes through the cooperation between the first protrusion 101 and the first groove 2011 and the limiting groove 301. At the same time, the first protrusion 101 is circumferentially set as a flat surface, which can better achieve cooperation and is more convenient in manufacturing and processing.

A first sealing ring 60 is provided between the first protrusion 101 and the first groove 2011 , and a second sealing ring 70 is provided between the first protrusion 101 and the limiting groove 301 , which can seal the passages between the two pipes and the outside world, thereby achieving a better sealing effect.
