Abstract
The utility model relates to the technical field of pipe fitting connection, and provides a pipe fitting connection mechanism for glass-lined pipes, which includes: a glass-lined pipe fitting main body and two flange plates, and further includes: a connection component arranged at one end of the glass-lined pipe fitting main body. The connection component includes: an extension pipe fixedly arranged on one side of the flange plate, and a sealing ring fixedly arranged on the outer surface of the extension pipe; an annular plate fixedly arranged on the side of the flange plate close to the extension pipe, and a thread groove is opened on the outer surface of the annular plate. The extension pipe on one side of the flange plate is embedded into the interior of the glass-lined pipe fitting main body. The extension pipe can not only improve the stability of the flange plate, but also improve the sealing performance through the sealing ring. The annular plate is sleeved on one end of the glass-lined pipe fitting main body, and a thread sleeve is sleeved on the outer surface of the glass-lined pipe fitting main body, so that the thread sleeve is connected with the annular plate through the thread groove. After the thread sleeve is installed on the outer surface of the annular plate, the thread sleeve is positioned by a positioning bolt.
