Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to an inverted cone joint suitable for pipes with multiple diameters. Background Art

[0002] The inverted cone joint is a joint used for pipe connection. It is designed with an externally threaded threaded sleeve and a gasket to achieve a tight connection. It is mainly used for the connection of PTFE, FEP, PFA and other pipes. When using it, just put the inverted cone plug and the pressure ring on the pipe and screw it into the interface. It has the advantages of easy operation, economy and durability.

[0003] The utility model patent with the authorization announcement number CN209781911U discloses an integrated inverted cone joint, which is used to connect pipe fittings with pipe fitting interfaces. The inverted cone joint is hollow, and the main body is a threaded section. The threaded section is provided with a truncated cone structure and a circular ring structure in sequence forward, and the threaded section is provided with a shoulder and a fastening component in sequence backward, and the various parts of the inverted cone joint are integrally formed. During the pipe connection process, no additional sealing ring is required, and the integrated inverted cone joint can be used multiple times, thereby saving costs; during disassembly, the pressure ring will not be difficult to remove from the interface after deformation, making it more convenient for operators to assemble and disassemble; the edge deformation of the circular ring structure is used to play the role of line sealing, overcoming the shortcomings of the previous joint using surface sealing, making the sealing effect better, and also greatly reducing the processing accuracy requirements of the interface and the inverted cone joint.

[0004] Although the integrated inverted cone joint improves the sealing effect, the device still has the following shortcomings in actual use. Specifically, in actual applications, it is often necessary to connect pipes of different diameters, and since the size of the main threaded section is fixed, it is difficult for the device to adapt to different pipe diameters. Therefore, when the device is used to meet the needs of connecting pipes of different diameters, its scope of use is limited to a certain extent. In view of this, we propose an inverted cone joint suitable for multiple pipe diameters. Utility Model Content
