Pipeline elbow connector

The invention discloses a pipeline elbow connector which comprises a shell, wherein the inside of the shell is a spherical chamber, the shell is also provided with an inlet and an outlet, the inlet and the outlet respectively communicate with a material inlet pipe and a material outlet pipe, and the diameter of the spherical chamber is 3-6 times that of the diameter of the material inlet pipe and the diameter of the material outlet pipe. During working, because the diameter of the spherical chamber is greater than the diameter of the material inlet pipe and the diameter of the material outlet pipe, when a material enters the spherical chamber, firstly, because the flowing rate is inversely proportional to the sectional area, the flowing rate in the spherical chamber is greatly lower than the flowing rate in the material inlet pipe and the flowing rate in the material outlet pipe, and secondly, due to the structural characteristics of the spherical chamber, the material first entering the spherical chamber for
