Description

Technical Field

[0001] The utility model relates to the field of pipe joints, in particular to a novel variable-diameter pipe joint structure. Background Art

[0002] Pipe joints are components that connect two or more pipes in a piping system and are used to achieve fluid transmission and control. With the continuous development of industry, a large number of pipes need to be laid in some places to transport fluid media or materials. In the specific design process, pipes of different diameters need to be connected to each other through pipe joints.

[0003] When facing the connection of pipes of different diameters, a reducing joint is needed. After the pipes are connected with a reducing joint, the flow velocity of the liquid will suddenly increase when it flows from the large diameter to the small diameter. Therefore, at the moment of velocity change, a large impact force will be generated on the small diameter pipe. When the existing reducing joints are connected to the pipes, they are mostly fixed by threads and external locking rings. There is a large impact force in pipeline transportation. This type of connection method has poor stability and is prone to leakage and detachment, resulting in a certain waste of medium.

[0004] Therefore, the utility model proposes a novel variable diameter pipe joint structure. Utility Model Content

[0027] like Figure 1 and Figure 4As shown, the reducer 8 is arranged as a whole in a conical joint, the first connecting part 9 is arranged horizontally in a ring shape, and its outer end surface is provided with a thread corresponding to the connecting end of the first pipe 1, and the sealing part 10 is located on the inner end surface of the first connecting part 9, and a plurality of groups of rubber sealing rings are provided on its surface. The side section of the compensation layer 17 is arranged in an "L"-shaped step, which is arranged as a rubber layer. At the same time, the compensation layer 17 and the sealing part 10 are embedded in the arrangement. The reducer 8 is used to facilitate the diameter reduction connection between the first pipe 1 and the second pipe 2. The first connecting part 9 is used to achieve the effect of connecting the reducer 8 and the interface end of the first pipe 1. The sealing part 10 cooperates with the compensation layer 17 to ensure that the interface end of the reducer 8 and the first pipe 1 are sealed.

[0028] When the reducer 8 is connected to the interface end of the first pipe 1, a threaded connection is made through the outer end of the first connecting portion 9 and the inner side of the interface end of the first pipe 1, and the sealing portion 10 is located at the outer side of the interface end of the first pipe 1. At this time, the outer hoop 4 is sleeved between the first connecting portion 9 and the interface end of the first pipe 1, and the compensation layer 17 is attached to the sealing portion 10 to achieve sealing processing of the interface end of the first connecting portion 9 and the first pipe 1 from the outer position.

[0029] like Figure 2-3 As shown, the surface of the second connecting portion 12 is provided with a thread corresponding to the inner side of the second pipe 2, the mounting portion 11 is provided in an annular protrusion, and is movably sleeved with the reinforcement outer ring 13. A group of rubber washers are also provided on the inner side of the reinforcement outer ring 13, and four groups of limiting grooves 14 are opened laterally along the outer surface of the reinforcement outer ring 13. The second connecting portion 12 is used to facilitate the threaded connection between the interface end of the second pipe 2 and the reducer 8. The mounting portion 11 is used to achieve the effect of connecting and fixing the reinforcement outer ring 13 and the reducer 8. The limiting grooves 14 on the mating surface of the reinforcement outer ring 13 are used to achieve the effect of connecting and fixing the adjustment ring 15.

[0030] The adjusting ring 15 is simultaneously movably sleeved on the interface end of the second pipe 2, the adjusting ring 15 and the threaded portion 7 are threadedly sleeved, and the fixed support plate 16 is arranged in an "L" shape, and four groups are arranged outwardly along the edge of the adjusting ring 15. The outer end of the fixed support plate 16 is arranged at an angle and embedded in the limiting groove 14. The outer stop ring 5 and the first pipe 1 are fixedly sleeved, and the outer ring 13 is connected and reinforced by the adjusting ring 15 and the fixed support plate 16 to fix the second pipe 2 and the reducer 8. The outer stop ring 5 is used to limit the adjusting ring 15.

[0031] When connecting the reducer 8 and the interface end of the second pipe 2, the second connecting part 12 is threadedly connected to the inner side of the interface end of the second pipe 2. At this time, the reinforcement outer ring 13 is located at the outer end of the interface end of the second pipe 2. Then the user makes the outer end of the fixed support plate 16 embedded in the limiting groove 14 on the surface of the reinforcement outer ring 13, and then rotates the adjusting ring 15. The rotation of the adjusting ring 15 makes it move away from the interface position of the second pipe 2 and the reducer 8. At this time, the rotation of the adjusting ring 15 simultaneously pulls the fixed support plate 16 to slide along the limiting groove 14, thereby realizing the reinforcement treatment between the reducer 8 and the interface end of the second pipe 2. In this process, the rotation of the adjusting ring 15 simultaneously drives the rotation of the reinforcement outer ring 13 at the mounting portion 11 under the action of the fixed support plate 16.

[0032] The working principle of the present invention is as follows: when the device is in use, the two sections of the pipeline are first connected by a basic diameter reduction through the reducer 8, and the basic threaded connection is realized by cooperating with the first connecting part 9 and the second connecting part 12. When the second pipeline 2 with a small diameter is connected to the reducer 8, the rotatable and adjustable reinforcement component 6 is combined with the reinforcement outer ring 13 to effectively ensure the connection stability between the interface end of the second pipeline 2 and the reducer 8, and avoid the strong impact force when the medium flows, which causes the interface position of the two to be separated.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
