Description

Technical Field

[0002] Stainless steel pipes are widely used in today's society. In some specific installation situations, stainless steel pipes of different lengths often need to be sealed and connected. Traditional connection methods mostly use welding connections, which directly seal the stainless steel pipes. In the later stage, the stainless steel pipes need to be cut for maintenance, which has disadvantages. At present, mechanical sealing connection methods such as conical connection and threaded connection are also used. The conical connection force is small, which easily causes the interface to be unsealed. Although the threaded connection has a large connection force, there are gaps in the mutual matching of the threads, which easily causes the interface to be poorly sealed.

The left pipe wall and the right pipe wall are connected by a threaded mechanism, and a sealing rubber pad is arranged at the end of the inner thread groove of the left pipe wall, and the front end of the outer thread of the right pipe wall is closely attached to the sealing rubber pad. A T-shaped sealing pad is arranged at the end face of the outer connection of the left pipe wall and the right pipe wall, and the upper part of the T-shaped sealing pad covers the outer wall surface of the left pipe wall and the right pipe wall. It adds a new sealing link to the structural technology of the traditional threaded connection seal, so that the connected stainless steel pipes are fully and tightly combined together, the sealing is stronger and more stable, and does not affect the later maintenance and disassembly.
