Technical Field

[0001] The present application relates to the technical field of pipeline connection, and in particular to a corrosion-resistant pipe concentric head connector. Background Art

[0002] In pipeline engineering and fluid transmission systems, pipe connection technology has always been an important factor in ensuring the normal operation of the entire system. In recent years, with the acceleration of industrialization and the continuous improvement of technology, industrial pipeline systems have been widely used in many industries such as chemical, petroleum, and shipbuilding. Pipeline connection is not only related to the stability of the system, but also directly affects production efficiency and safety. Therefore, research and development of efficient pipeline connection technology is of great significance to promoting the modernization and automation of industrial production.

[0003] At present, the pipe connection methods commonly used in the industry mainly include flange connection, welding connection and threaded connection. Flange connection fixes two pipes together through bolts on the flange plate, which is suitable for the connection of large-diameter pipes; welding connection uses welding technology to permanently connect two pipes together, which is suitable for occasions requiring high-strength connection; threaded connection is to process threads on both ends of the pipe and achieve connection by screwing, which is suitable for quick connection of small-diameter pipes. In addition, there are some special connectors, such as compression fittings and quick-plug fittings. These connectors are usually designed with specific locking mechanisms that can achieve quick connection and disassembly without the use of tools.

[0004] Regarding the above-mentioned related technologies, flange connection requires a large installation space and a long assembly time, and is prone to sealing failure in the case of frequent disassembly and assembly; although the welding connection has high strength, once there is a problem with the welding point, the maintenance cost is high; although the threaded connection is easy to operate, it is difficult to ensure the coaxiality of the pipe fittings during the connection process, which is prone to leakage. These problems seriously affect the reliability and service life of the existing connection technology in some special application scenarios. Therefore, how to effectively improve the convenience of pipe connection is still a technical problem that needs to be solved urgently. Summary of the invention

Through the design of the adjustment rod, it is ensured that the connector can be flexibly adjusted at different positions to adapt to various installation requirements, thereby improving the scope of application of the connector; the wavy plug-in ring design of the plug-in can effectively increase the contact area and improve the sealing performance.

[0054] Reference Figure 8In order to make the plug-in ring 542 have anti-corrosion properties, on the one hand, the surface of the plug-in ring 542 can be provided with an anti-corrosion layer, which is made of epoxy resin material. Epoxy resin has excellent corrosion resistance and can effectively resist the erosion of various chemical substances. The thickness of the anti-corrosion layer is 0.8 mm, which can provide sufficient protection without significantly increasing the weight and cost of the connector. In addition to epoxy resin, other high-performance anti-corrosion coatings can also be selected, such as polyurethane, fluorocarbon paint, etc. These materials also have excellent anti-corrosion properties; on the other hand, the material of the plug-in ring 542 can also be carbon steel, which is an economical and affordable The material has high mechanical strength and good processing performance, but the corrosion resistance of carbon steel itself is poor.

Through observation by personnel, the rotating member 35 is started, and the pipes 6 connected to the fasteners 33 are adjusted. When the pipes 6 are adjusted to a suitable position, the guide cylinder 41 in the guide component 4 is started so that the two magnets 43 can be attracted to each other, and then the pipes 6 are further fixed by the two connectors 53 in the connecting component 5. Then the adjusting component 2 is started to connect the two connectors 54 on the pipes 6. After that, the personnel further seal and fix the connection between the two pipes 6.

[0057] When the connecting part 53 is needed to fix the pipeline 6, first, when the pipeline 6 needs to be fixed, start the pushing cylinder 533, and the pushing cylinder 533 drives the second arc plate 534 to move away from each other. The personnel moves the two sliding rods 531, and through observation, the sliding rods 531 are moved to the appropriate position. Then, start the two pushing cylinders 533, and the pushing cylinders 533 can push the second arc plates 534 to move toward each other, so that the two second arc plates 534 fix the pipeline 6. Then, when the adjusting component 2 drives the pipeline 6 to move, the sliding rod 531 slides in the through groove 3321 until the connection of the two connectors 54 is completed.
