Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a rotatable multi-port pressure pipeline connection device. Background Technology

[0002] Pipeline connection devices are mainly used in petrochemical, natural gas transportation, and marine propulsion systems to achieve flexible connections for multi-directional fluid transmission in pressure pipeline systems. Through special structural design, these devices ensure sealing while allowing pipe interfaces to rotate at multiple angles to meet the pipeline layout requirements under complex operating conditions.

[0003] Existing pressure pipeline connection devices typically use fixed flange connections or welding methods, where the flange is bolted and sealed with a gasket to achieve the pipeline connection, or the pipeline ends are directly welded and fixed. When the pipeline needs to be branched or the layout needs to be adjusted, the pipeline must be disassembled, cut and welded again, resulting in low installation efficiency and large material waste. To address these issues, a rotatable multi-port pressure pipeline connection device is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rotatable multi-port pressure pipeline connection device, which aims to improve the problem of poor pipeline connection flexibility in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotatable multi-port pressure pipeline connection device includes a pipe body and a sealing pipe. A fixed pipe shell is fixedly connected to the outside of the pipe body. A connecting pipe is fixedly connected to the middle of the outside of the fixed pipe shell. A connecting assembly is installed on the outside of the connecting pipe. A fixing assembly is installed on the outside of the pipe body.

[0007] The connecting assembly includes a connecting block, which is fixedly connected inside the fixed tube shell. A sliding groove is provided in the middle of the connecting block, and a slot is provided inside the sliding groove. A housing is rotatably connected to the outside of the connecting block, and a locking post is fixedly connected inside the housing. The locking post is slidably connected to the middle of the sliding groove and engages with the slot.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes a connecting pipe three, a locking block fixedly connected to the end of the connecting pipe three, a groove provided inside the sealing pipe, the locking block engaging with the groove, a handwheel fixedly connected to the outside of the connecting pipe three, the handwheel being threadedly connected to the outside of the sealing pipe, a sealing ring fixedly connected inside the sealing pipe, and the pipe body slidably connected inside the connecting pipe three, with the sealing ring contacting the outside of the pipe body;

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

[0011] A spring rod is fixedly connected inside the slide groove, and an inclined block is fixedly connected to the bottom of the spring rod. The inclined block is in contact with the locking post.

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

[0013] The fixed tube shell is internally connected to a connecting pipe four, and the connecting pipe four is externally provided with two flanges, with a sealing gasket between the two flanges;

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

[0015] A limiting block is fixedly connected inside the sealing tube, and the port of the tube body is in contact with the limiting block;

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

[0017] The bottom of the housing is fixedly connected to a connecting pipe 2;

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

[0019] The flange is threaded with a fixing bolt in the middle;

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

[0021] A pressure relief port is fixedly connected to the top of the pipe.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rotating housing drives the locking pin to slide in the groove, so that the locking pin and the groove are engaged. With the help of the spring rod and the inclined block, the locking pin is firmly fixed in the groove, which facilitates the adjustment of pipeline layout under complex working conditions, improves safety and efficiency, and reduces installation losses and costs.

[0024] 2. In this utility model, when the handwheel thread is tightened, it pushes the connecting pipe to compress the sealing ring, making it fit tightly against the outer wall of the pipe. At the same time, the combination of the flange and the sealing gasket further enhances the sealing performance of the connection, which can effectively prevent the leakage of medium in the pressure pipeline and meet the usage requirements under high pressure conditions.

[0032] 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.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a rotatable multi-port pressure pipeline connection device, comprising a pipe body 1 and a sealing pipe 16. A fixed pipe shell 6 is fixedly connected to the outside of the pipe body 1. A connecting pipe 2 is fixedly connected to the middle of the outside of the fixed pipe shell 6. A connecting assembly is installed on the outside of the connecting pipe 2. A fixed assembly is installed on the outside of the pipe body 1. The connecting assembly includes a connecting block 9, which is fixedly connected to the inside of the fixed pipe shell 6. A sliding groove 10 is formed in the middle of the connecting block 9. A slot 22 is provided inside the sliding groove 10. A housing 3 is rotatably connected to the outside of the connecting block 9. A locking post 8 is fixedly connected inside the housing 3. The locking post 8 is slidably connected to the middle of the sliding groove 10 and engages with the slot 22. A spring rod 20 is fixedly connected inside the sliding groove 10. An inclined block 21 is fixedly connected to the bottom of the spring rod 20 and contacts the locking post 8. Rotating the housing 3 causes the locking pin 8 to slide inside the slide groove 10 and engage with the locking groove 22. The inclined surface of the wedge block 21 provides limiting, ensuring a tight fit between the locking pin 8 and the locking groove 22, thus achieving a fixed connection between connecting pipe 1 2 and connecting pipe 2 5. The spring rod 20 provides upward elastic support, ensuring a stable engagement state, preventing accidental loosening, ensuring sealing during rotation, and preventing media leakage. This allows for rapid adjustment to adapt to complex pipeline layouts. The fixed housing 6 internally houses a connecting pipe 4 13, with two flanges 4 on the outside of the connecting pipe 4 13. A sealing gasket 12 is placed between the two flanges 4 on the outside of the connecting pipe 4 13. Tightening the fixing bolts 11 compresses and deforms the sealing gasket 12, forming a tight sealing surface to prevent fluid leakage from the flange connection. Since the medium in pressure pipelines is typically under high pressure, the sealing gasket 12 enhances the sealing effect, preventing loosening and leakage due to vibration or pressure fluctuations. A limiting block 15 is fixedly connected inside the sealing pipe 16, and the port of the pipe body 1 is in contact with the limiting block 15. A connecting pipe 5 is fixedly connected to the bottom of the shell 3. A fixing bolt 11 is threadedly connected to the middle of the flange 4. A pressure relief port 23 is fixedly connected to the top of the pipe body 1. The pressure relief port 23 at the top of the pipe body 1 automatically releases excess pressure when the internal pressure is abnormal, preventing the pipe from bursting.

[0034] Reference Figure 1 and Figure 4The fixing assembly includes a connecting tube 3 7, with a locking block 18 fixedly connected to the end of the connecting tube 3 7. A groove 19 is provided inside the sealing tube 16, and the locking block 18 engages with the groove 19. A handwheel 14 is fixedly connected to the outside of the connecting tube 3 7, threadedly connected to the outside of the sealing tube 16. A sealing ring 17 is fixedly connected inside the sealing tube 16. The tube body 1 is slidably connected inside the connecting tube 3 7, and the sealing ring 17 contacts the outside of the tube body 1. Turning the handwheel 14 counterclockwise separates it from the tube body 1, pushing the tube body 1 and other connecting tubes 1 2 into the sealing tube 16. Under the limiting action of the limiting block 15, the sealing ring compresses the tube body 1 completely into the sealing tube 16, achieving a seal. Turning the handwheel 14 clockwise causes the connecting tube 3 7 and the locking block 18 to slide towards the sealing tube 16 and engage with the groove 19, thus tightly closing the sealing tube 16.

[0035] Working principle: The locking pin 8 on the housing 3 is aligned with and inserted into the slide groove 10. It slides downwards along the slide groove 10 to the locking slot 22. Rotating the housing 3 causes the locking pin 8 to slide inside the slide groove 10 and engage with the locking slot 22. The inclined surface of the wedge block 21 provides a limiting effect, ensuring a tight engagement between the locking pin 8 and the locking slot 22, thus achieving a fixed connection between connecting pipe 1 2 and connecting pipe 2 5. The spring rod 20 provides upward elastic support, ensuring a stable engagement and preventing accidental loosening. For disassembly, rotating the housing 3 in the opposite direction causes the locking pin 8 to slide out of the locking slot 22 along the inclined surface of the wedge block 21, disengaging from the slide groove 10, allowing for quick separation of connecting pipe 1 2 and connecting pipe 2 5.

[0036] Connecting pipe 3 7 is positioned by engaging with groove 19 via locking block 18. When the handwheel 14 is tightened, it pushes connecting pipe 3 7 inward, causing sealing ring 17 to fit tightly against the outer wall of pipe body 1, forming a seal. Connecting pipe 4 13 inside fixed pipe shell 6 is connected to external pipe via flange 4, sealing gasket 12, and fixing bolts 11. Limiting block 15 prevents over-connection of pipe body 1 with other connecting pipes, ensuring sealing accuracy. Connecting pipe 2 5 at the bottom of shell 3 and connecting pipe 1 2 in the middle of fixed pipe shell 6 form a multi-port layout, which, together with the rotating structure, enables rapid docking of pipes in different directions.

[0037] 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.
