Description

Technical Field

[0002] With the development of society, sealing rings are widely used in the mechanical field. Sealing rings are a kind of annular mechanical parts with a circular cross-section. They are now mostly made of rubber or Teflon materials with a certain elasticity. Sealing rings are often used for static sealing between shafts and holes, mainly to prevent liquid or gas leakage.

[0003] In the prior art, when installing a mechanical tee, it is necessary to place the upper and lower clamps on the pipe, and use a set of bolts and nuts to fix the connection. Before installation, the bolts and nuts on both sides of the mechanical tee need to be removed, and then the upper and lower clamps are buckled together during installation, and the mechanical tee assembly is installed on the corresponding pipe using bolts and nuts. During installation, the bolts and nuts are easy to fall off, causing chaos on the installation site, low installation efficiency, and high labor costs. In order to ensure the sealing effect of the connection, a sealing ring is usually used. The existing rubber sealing ring has low compressive strength. During use, the sealing ring is subjected to a large pressure, which is easy to cause damage to the sealing ring and cannot be used for a long time. Utility Model Content
