Flared type seamless connector with composite ring

Abstract

The invention relates to a seamless connector, in particular to a flared type seamless connector with a composite ring. The flared type seamless connector with the composite ring has the characteristics of being wear resistant, corrosion resistant, high in strength and extrusion resistant; and in the meantime, the seamless connector is further characterized by being light in weight, simple in structure, easy to machine, low in the fabrication cost, easy to recycle in an environment-friendly manner, easy to popularize and easy to install and transport. The flared type seamless connector with the composite ring comprises a connection pipe, a first lining ring and a second lining ring. A flared opening is arranged at an end of the connection pipe. A first shoulder portion is arranged at the connecting position of the flared opening and the connection pipe. A first abutting-connected portion which is connected with the inner wall of the flared opening in an abutting manner is arranged at an end of the first lining ring, and a second shoulder portion is arranged at the other end of the first lining ring. A support portion for supporting the second lining ring is arranged on one side ofthe second shoulder portion. A second abutting-connected portion which is connected with the inner wall of the flared opening in an abutting manner is arranged on the periphery of the second lining ring. One end of the second lining ring is connected with the second shoulder portion in an abutting manner, and the other end of the second lining ring is connected with the first shoulder portion in an abutting manner.

Description

Technical field

[0001] The invention relates to a seamless joint, in particular to a flared seamless joint with a composite ring. Background technique

[0002] The current connection between plastic pipes or plastic composite pipes is mostly direct welding, or connection through movable metal flanges after welding flange roots, or connection through movable metal flanges after direct flanging. The disadvantage is that it is difficult to repair and replace the pipelines directly welded; the pipelines connected after welding with flange roots and the pipelines connected directly after flanging have limited use environment, floating on the water surface, and the joints are easy to break.

[0003] The use of seamless joints can effectively avoid the above-mentioned problems. Seamless joints mainly have the following forms:

[0004] 1. The flared seamless joint lined with metal ring (patent number ZL201120415234.4), the disadvantage is that the metal ring is directly exposed, heavy, easy...
