Description

Technical Field

[0001] The utility model belongs to the technical field of flange joints, and in particular relates to a novel flange conversion joint assembly. Background Art

[0002] Currently, the primary methods for connecting pipes are welding, threaded connections, and flange connections. Welded pipes cannot be disassembled, making them inconvenient for pipe repair or replacement. Threaded pipe connections require disassembly from the original connection point, making repair or replacement very cumbersome. A flange connection involves securing two pipes, fittings, or devices to be connected, each secured to a flange plate. A flange gasket is placed between the two flanges, and the flanges are then bolted together to complete the connection. Pipes or fittings of different specifications are converted using flange adapters.

[0003] However, existing flange adapters suffer from two major technical issues: a. Pipes and fittings can slip or loosen over extended periods of operation, leading to unstable connections and sometimes leaks or other failures; b. The lack of an effective flow control mechanism makes flow regulation difficult, making it impossible to precisely control flow. Therefore, resolving these issues is a pressing technical challenge within the industry. Utility Model Content

The fixing bolt 4 can be rotated through the threaded connection to apply a predetermined pressure, thereby tightening the connection between the first flange 1 and the second flange 2, ensuring that there is no gap between them and preventing fluid leakage. The fixing bolt 4 can transmit torque by engaging with the thread groove between the two flanges through the thread, making the connection more secure. The design of the threaded connection generally allows the fixing bolt 4 to be easily disassembled when necessary, facilitating maintenance or replacement of the connected components. A rubber ring 5 is provided between the first flange 1 and the second flange 2. This design is intended to provide additional sealing performance between the two flanges and ensure the leakage-proof capability of the connection.
