Description

Technical Field

[0001] This utility model belongs to the field of pipe joints, specifically relating to a water-coal slurry pipe joint. Background Technology

[0002] Water-coal slurry pipeline systems are typically composed of pipes of different diameters, such as 300mm, 200mm, and 100mm, to adapt to different transportation needs and operating conditions.

[0003] During pipeline layout, it is often necessary to connect pipes of different diameters. The traditional method is to use reducers to transition between different diameters.

[0004] However, current reducing fittings are usually connected by welding or flanges. When repairing or replacing water-coal slurry pipeline systems, a large number of bolts need to be cut or removed, which is cumbersome and affects maintenance efficiency.

[0005] Therefore, we propose a water-coal slurry pipeline joint to solve the above problems. Utility Model Content

[0006] To address the problem that current reducing couplings typically use welding or flange connections, which require cutting or disassembling a large number of bolts during the maintenance or replacement of coal-water slurry pipeline systems, resulting in cumbersome operations, this utility model provides a coal-water slurry pipeline coupling.

[0007] The solution adopted by this utility model to solve its technical problem is: a water-coal slurry pipe joint, including a male joint and a female joint. The male joint is provided with a mating hole, a small joint hole and a middle joint hole from left to right. The mating hole, the small joint hole and the middle joint hole are interconnected. The inner walls of the small joint hole and the middle joint hole are respectively provided with internal threads.

[0008] The female connector has a large connection hole and a middle connection hole 2 from left to right. The large connection hole and the middle connection hole 2 are interconnected. The inner walls of the large connection hole and the middle connection hole 2 are respectively provided with internal threads 2.

[0009] The outer diameter of the female connector is adapted to the diameter of the mating hole, allowing the female connector to be inserted into the mating hole, and the female connector and the male connector can be detachably connected.

[0010] Preferably, the left end of the male connector is fitted with a flange, the left end of the female connector is fitted with a mating plate, a sealing gasket is provided between the flange and the mating plate, and they are connected by multiple bolts.

[0011] Preferably, a spacer ring is fixedly connected to the side of the mating hole near the small mating hole, and a sealing gasket and a small sealing gasket are respectively provided on the left and right sides of the spacer ring.

[0012] Preferably, a central sealing gasket is provided on the side of the central connection hole near the small connection hole.

[0013] Preferably, a large sealing gasket is provided on the side of the large connection hole near the second intermediate connection hole.

[0014] Preferably, the diameter of the large connector hole is 300mm, the diameters of the first and second intermediate connector holes are both 200mm, and the diameter of the small connector hole is 100mm.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the design of the small and medium connecting holes on the male connector and the large and medium connecting holes on the female connector, enables the connector to adapt to the connection requirements of 100mm, 200mm and 300mm pipes. The pipe is connected to the male and female connectors by threaded connection, which not only ensures the stability and sealing of the connection, but also facilitates the separation and disassembly of the female or male connector from the pipe. Furthermore, the male and female connectors can be separated by removing the bolts, which greatly reduces the amount of disassembly work and significantly improves maintenance efficiency.

[0017] 2. This utility model separates the male and female connectors, making it easy to connect them to the threaded ends of the pipes on both sides. On-site assembly can be completed simply by connecting the flanges and tightening the bolts, greatly reducing the difficulty of installation.

[0018] 3. By setting a sealing gasket 1, a sealing gasket 2, a small sealing gasket, a medium sealing gasket, and a large sealing gasket, this utility model can effectively fill the gaps when the pipeline is connected to the male or female joint, greatly preventing leakage of water-coal slurry during transportation and ensuring the safety and stability of the pipeline system.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-3 This utility model provides a technical solution for a water-coal slurry pipeline joint:

[0025] Example 1:

[0026] according to Figure 1-3 As shown, it includes a male connector 1 and a female connector 3. The male connector 1 has a mating hole 14, a small connecting hole 12 and a middle connecting hole 11 from left to right. The mating hole 14, the small connecting hole 12 and the middle connecting hole 11 are interconnected, so that the coal-water slurry can flow in the inner hole of the male connector 1. The inner walls of the small connecting hole 12 and the middle connecting hole 11 are respectively provided with internal threads to facilitate threaded connection with the threaded end of the pipe.

[0027] A spacer ring 5 is fixedly connected to the side of the connecting hole 14 near the small connecting hole 12. A sealing gasket 51 and a small sealing gasket 52 are respectively provided on the left and right sides of the spacer ring 5. A middle sealing gasket 13 is provided on the side of the middle connecting hole 11 near the small connecting hole 12. By setting the small sealing gasket 52 and the middle sealing gasket 13, the gap when the pipe is connected to the male connector 1 can be effectively filled, which greatly prevents leakage of water-coal slurry during transportation and ensures the safety and stability of the pipeline system operation.

[0028] The female connector 3 has a large connecting hole 31 and a second intermediate connecting hole 32 sequentially from left to right. The large connecting hole 31 and the second intermediate connecting hole 32 are interconnected, allowing the coal-water slurry to flow in the inner hole of the female connector 3. The inner walls of the large connecting hole 31 and the second intermediate connecting hole 32 are respectively provided with internal threads. A large sealing gasket 33 is provided on the side of the large connecting hole 31 near the second intermediate connecting hole 32. By setting the large sealing gasket 33 and the sealing gasket 51, the gap when the pipeline is connected to the female connector 3 can be effectively filled, which greatly prevents the coal-water slurry from leaking during transportation and ensures the safety and stability of the pipeline system.

[0029] The outer diameter of the female connector 3 is adapted to the diameter of the mating hole 14, so that the female connector 3 can be inserted into the mating hole 14. The left end of the male connector 1 is fitted with a flange 2, and the left end of the female connector 3 is fitted with a mating plate 4. By setting the male connector 1 and the female connector 3 separately, it is easy to connect the male connector 1 and the female connector 3 to the threaded ends of the pipes on both sides respectively. On-site assembly can be completed by simply mating the flange 2 and tightening the bolts 6, which greatly reduces the difficulty of installation.

[0030] A sealing gasket 2 7 is provided between the flange 2 and the mating plate 4, and they are connected by multiple bolts 6, which makes the female connector 3 and the male connector 1 detachable, greatly reducing the amount of disassembly work and significantly improving maintenance efficiency.

[0031] In practical use, the water-coal slurry pipe joint of this utility model first connects the threaded end of the pipe to the small hole 12 or the middle hole 11 of the male connector 1 according to the diameter of the pipe. Then, according to the diameter of the other pipe, the threaded end of the other pipe is connected to the large hole 31 or the middle hole 32 of the female connector 3.

[0032] After connecting and securing the male connector 1 and female connector 3 to the threaded ends of the two pipes respectively, align the female connector 3 with the mating hole 14 of the male connector 1 and manually insert the female connector 3 into the mating hole 14. Finally, place the sealing gasket 2 7 between the flange 2 and the mating plate 4, and use bolts 6 to connect and secure the flange 2 and the mating plate 4 to ensure a tight connection between the male connector 1 and the female connector 3.

[0033] Example 2:

[0034] Based on Example 1, such as Figure 1 As shown, the diameter of the large connecting hole 31 is 300mm, the diameters of the middle connecting holes 11 and 32 are both 200mm, and the diameter of the small connecting hole 12 is 100mm. This allows the connector to adapt to pipe connection requirements of 100mm, 200mm and 300mm, effectively solving the limitations of traditional reducers in pipe diameter adaptation and improving the versatility and practicality of pipe connectors.
