Pipe fitting and saddle connection structure

Abstract

The invention relates to the field of pipe structures, in particular to a pipe fitting and saddle connection structure. A connection hole is formed in the side wall of a pipe body of the structure. Aconnecting ring is arranged on the outer side wall of the end portion of a cylinder body in a surrounding manner. A first connecting groove and a second connecting groove are formed in a ring-shaped connecting part, wherein an opening of the first connecting groove and an opening of the second connecting groove are arranged away from each other. The edge of the connection hole is embedded into thefirst connecting groove. The edge of the connection hole is connected to the inner wall of the first connecting groove in an abutting-against manner. The connecting ring is embedded into the second connecting groove. The connecting ring is connected to the inner wall of the second connecting groove in an abutting against manner, thus the connecting part can be closely connected to the pipe body and the cylinder body, the connecting grooves in the connecting parts can seal the connecting portion of the pipe body and the cylinder body, and can also locate and fasten the pipe body and the cylinder body to enable the pipe body and the cylinder body to be connected closely, the connecting part can avoid the phenomenon of swelling between the pipe body and the cylinder body, and the sealing performance of the pipe body and the cylinder body is ensured.

Description

technical field [0001] The invention relates to the field of pipe structures, in particular to a saddle connection structure for pipe fittings. Background technique [0002] The connection between the branch pipe and the main pipe of the existing fluid conveying pipeline is generally connected in the form of saddle connection, that is, the side wall of the main pipe is provided with a saddle port, the branch pipe is inserted into the saddle port, and the branch pipe and the main pipe are locked by self-tapping screws. The connection between the main pipe and the branch pipe is adaptively injected with silicone to improve the sealing of the connection. Because there is a certain deviation between the saddle mouth on the main pipe and the arc edge on the plug-in end of the branch pipe, after the main pipe and the branch pipe are locked with self-tapping screws, there will be a bulge at some connections, that is, the partial connection between the main pipe and the branch pipe ...
