Description

Technical Field

[0001] This utility model relates to the field of wear-resistant pipe splicing technology, and in particular to a high-pressure wear-resistant pipe quick splicing component. Background Technology

[0002] High-pressure wear-resistant pipes are mainly used to transport fluids under high pressure. They are usually made of metal, such as high-strength alloys and wear-resistant cast iron. These metal materials have excellent mechanical properties, which can withstand the huge impact of high pressure and effectively resist the scouring and wear of hard particles in the fluid, ensuring the stable operation of the pipeline system.

[0003] In practical applications, the length of high-pressure wear-resistant pipes often needs to be adjusted according to specific construction requirements, which is usually achieved through splicing using flanges. Flanges, as a common pipe connection component, can firmly connect two or more sections of high-pressure wear-resistant pipe together. By using flanges for splicing, high-pressure wear-resistant pipes of different lengths can be flexibly combined, thereby achieving free control of pipe length and meeting installation requirements under various complex working conditions.

[0004] Using flanges to connect high-pressure wear-resistant pipes also has certain drawbacks. Flange connections often require multiple bolts for locking, and during installation, workers need to tighten these bolts one by one, which is not only cumbersome but also consumes a lot of time and manpower. Especially in large-scale projects that lay a large number of high-pressure wear-resistant pipes, this flange and bolt-dependent connection method will greatly reduce the efficiency of pipe splicing, thereby slowing down the entire construction progress. Therefore, a quick-connect fitting for high-pressure wear-resistant pipes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-pressure wear-resistant pipe quick splicing component, which aims to improve the problem mentioned in the prior art that "flange connections require locking with multiple sets of bolts, which is time-consuming and labor-intensive, reducing the efficiency of pipe splicing".

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-pressure wear-resistant pipe quick-connect assembly, comprising...

[0007] The first chuck has a discharge pipe fixedly connected to its right end;

[0008] The second chuck has a feed pipe fixedly connected to its left end. The outer walls of the first chuck and the second chuck are provided with a docking mechanism. The outer wall of the second chuck is provided with a pressing mechanism. The right end of the second chuck is fixedly connected with a sealing ring.

[0009] The docking mechanism includes a ball joint rod that passes through and is slidably connected to the inner wall of the second chuck. A spring is fixedly connected to the outer wall of the ball joint rod. The end of the spring away from the ball joint rod is fixedly connected to the outer wall of the second chuck. A tapered insert rod is fixedly connected to the left end of the first chuck. A limiting groove for inserting the ball joint rod is provided on the tapered insert rod. A through hole for inserting the tapered insert rod is provided on the second chuck.

[0010] As a further description of the above technical solution:

[0011] The clamping mechanism includes a rotating ring, which is rotatably connected to the outer wall of the second chuck, and a diagonal rod is fixedly connected to the right side of the rotating ring.

[0012] As a further description of the above technical solution:

[0013] The rotating ring has an inclined groove.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the second chuck is slidably connected to a slider, and a sliding shaft is fixedly connected to the side of the slider near the rotating ring. The outer wall of the sliding shaft is attached to the inner wall of the inclined groove.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the second chuck is rotatably connected to a threaded rod, which is threadedly connected to the slider.

[0018] As a further description of the above technical solution:

[0019] A handle is fixedly connected to the end of the threaded rod away from the second chuck.

[0020] As a further description of the above technical solution:

[0021] The inner wall of the limiting groove is provided with an inclined surface.

[0022] As a further description of the above technical solution:

[0023] The diameter of the discharge pipe is slightly smaller than the diameter of the feed pipe.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, the design of the docking mechanism enables the first chuck and the second chuck to be automatically locked together after they are docked. Compared with the traditional flange and bolt connection method, this can greatly improve the splicing efficiency between high pressure wear-resistant pipes, thereby accelerating the construction progress of high pressure wear-resistant pipes.

[0026] 2. In this utility model, through the design of the clamping mechanism, after the first chuck and the second chuck are docked together, a pushing force is applied to the first chuck towards the second chuck, so that the first chuck can squeeze the sealing ring. The sealing ring after compression and deformation can fill the small gap between the first chuck and the second chuck, thereby improving the sealing effect of the sealing ring and ensuring effective sealing between the first chuck and the second chuck.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3This utility model provides an embodiment of a high-pressure wear-resistant pipe quick-connect assembly, including a first chuck 1, with a discharge pipe 5 fixedly connected to the right end of the first chuck 1; a second chuck 2, with a feed pipe 6 fixedly connected to the left end of the second chuck 2. The diameter of the discharge pipe 5 is slightly smaller than the diameter of the feed pipe 6. Through the diameter difference between the discharge pipe 5 and the feed pipe 6, one set of high-pressure wear-resistant pipes can be inserted into the inner wall of the feed pipe 6, while another set of high-pressure wear-resistant pipes can be inserted into the outer wall of the discharge pipe 5. The outer walls of the first chuck 1 and the second chuck 2 are provided with a docking mechanism 3, and the outer wall of the second chuck 2 is provided with a pressing mechanism 4. A sealing ring 7 is fixedly connected to the right end of the second chuck 2, and the second sealing ring 7 can seal the space between the first chuck 1 and the second chuck 2.

[0035] Reference Figure 2 - Figure 4 The docking mechanism 3 includes a ball joint 31, which passes through and slides on the inner wall of the second chuck 2. A spring 32 is fixedly connected to the outer wall of the ball joint 31. The end of the spring 32 away from the ball joint 31 is fixedly connected to the outer wall of the second chuck 2. The elasticity of the spring 32 can drive the ball joint 31 to slide and reset on the inner wall of the second chuck 2. A tapered insert 33 is fixedly connected to the left end of the first chuck 1. A limiting groove 35 is provided on the tapered insert 33 for the ball joint 31 to be inserted. The ball joint 31 and the limiting groove 35 can be used to limit the tapered insert 33 to the inner wall of the through hole 34. The second chuck 2 is provided with a through hole 34 for the tapered insert 33 to be inserted. The through hole 34 and the tapered insert 33 can be used to dock the first chuck 1 and the second chuck 2 together.

[0036] Reference Figure 1 , Figure 3 and Figure 4The clamping mechanism 4 includes a rotating ring 41, which is rotatably connected to the outer wall of the second chuck 2. A diagonal rod 42 is fixedly connected to the right side of the rotating ring 41. By rotating the rotating ring 41 in conjunction with the diagonal rod 42, the ball head rod 31 can be squeezed, causing the ball head rod 31 to slide into the interior of the second chuck 2 and squeeze the inclined surface 48. A groove 43 is provided on the rotating ring 41. Under the limiting action of the groove 43, the slider 44 moves and drives the sliding shaft 45 to push the rotating ring 41, causing the rotating ring 41 to rotate on the outer wall of the second chuck 2. The inner wall of the second chuck 2 is penetrated and slidably connected to the slider 44. A sliding shaft 45 is fixedly connected to the side of the slider 44 near the rotating ring 41. The outer side of the sliding shaft 45... The wall is attached to the inner wall of the inclined groove 43. When the slider 44 moves, it will drive the sliding shaft 45 to move against the inner wall of the inclined groove 43. The inner wall of the second chuck 2 is rotatably connected to a threaded rod 46, which is threadedly connected to the slider 44. The end of the threaded rod 46 away from the second chuck 2 is fixedly connected to a handle 47. By rotating the threaded rod 46 through the handle 47, the threaded rod 46 drives the slider 44, which is threadedly connected to it, to slide on the inner wall of the second chuck 2. The inner wall of the limiting groove 35 is provided with an inclined surface 48. When the ball head rod 31 presses against the inclined surface 48, the ball head rod 31 will push the conical insert rod 33. At this time, the conical insert rod 33 will drive the first chuck 1 to gradually move closer to the second chuck 2.

[0037] Working principle: During use, the feed pipe 6 is inserted into the outer wall of the high-pressure wear-resistant pipe and welded together. Then, the discharge pipe 5 is inserted into the inner wall of the high-pressure wear-resistant pipe and welded together. When the two pipes need to be connected, the tapered insert 33 is inserted into the through hole 34. When the tapered insert 33 contacts the ball head rod 31 during insertion, the tapered surface of the tapered insert 33 will press against the ball head rod 31, causing the ball head rod 31 to slide along the inner wall of the second chuck 2 and gradually move away from the through hole 34. Simultaneously, the ball head rod 31 will stretch the spring 32. As the tapered insert 33 continues to be inserted, the limiting groove 35 will gradually approach the ball head rod 31. When the ball head rod 31 and the limiting groove 35 are connected... When the grooves 35 overlap, the elasticity of the spring 32 can drive the ball head rod 31 to insert into the interior of the limiting groove 35. At this time, the ball head rod 31, in conjunction with the limiting groove 35, can limit the tapered insert rod 33 to the inner wall of the through hole 34. Simultaneously, the positioning of the tapered insert rod 33 and the through hole 34 can limit the first chuck 1 and the second chuck 2 together, thus completing the connection of the two sets of pipes. It is worth noting that the fluid flow direction inside the high-pressure wear-resistant pipe is from the feed pipe 6 to the discharge pipe 5. Since the high-pressure wear-resistant pipe is inserted into the inner wall of the feed pipe 6, while the other set of high-pressure wear-resistant pipes is inserted into the outer wall of the discharge pipe 5, there will be no dead angle when the fluid flows inside the first chuck 1 and the second chuck 2, thereby maintaining the smoothness of the fluid.

[0038] After the ball joint 31 is inserted into the limiting groove 35, the threaded rod 46 is rotated by the handle 47, causing the threaded rod 46 to drive the slider 44, which is threadedly connected to it, to gradually slide out of the second chuck 2. At this time, the slider 44 will drive the sliding shaft 45 to move against the inner wall of the inclined groove 43. Under the limiting action of the inclined groove 43, the slider 44 will drive the sliding shaft 45 to push the rotating ring 41 while moving, causing the rotating ring 41 to rotate on the outer wall of the second chuck 2. While rotating, the rotating ring 41 will drive the inclined rod 42 to gradually approach the ball joint 31. When the inclined rod 42 contacts the ball joint 31, it will squeeze the ball joint 31. The ball joint 31 slides into the interior of the second chuck 2 and compresses the spring 32. At the same time, the ball joint 31 presses against the inclined surface 48, causing the ball joint 31 to push the tapered insert 33. At this time, the tapered insert 33 will drive the first chuck 1 to gradually move closer to the second chuck 2. During this process, the first chuck 1 will continuously apply pressure to the sealing ring 7, causing the sealing ring 7 to be deformed by compression. At this time, the deformed sealing ring 7 can fill the small gap between the first chuck 1 and the second chuck 2, thereby improving the sealing effect of the sealing ring 7 and ensuring an effective seal between the first chuck 1 and the second chuck 2.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
