Pipeline elbow connector

Abstract

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 forms vortex in the spherical chamber, so that materials entering the spherical chamber subsequently cannot easily directly scour the inner surface of the spherical chamber, thus effectively prolonging the service life of the product, reducing product change times, and further avoiding occurrence of conditions with adverse effect caused by change of products.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a pipeline elbow joint. Background technique [0002] Elbows are the fastest-wearing parts of dense medium coal preparation pipelines in coal preparation plants. When the fluid flows through the corner, under the action of inertial force, it will wash away the outer inner surface of the elbow, which will be worn through quickly, seriously reducing the service life of the elbow, and frequent replacement of the elbow is required in daily work. This will cause equipment shutdown, affect coal washing production, increase the maintenance workload of employees, increase on-site unsafe factors, and at the same time bring problems such as on-site running, emitting, dripping and leaking that are difficult to control, and a poor image of civilization and hygiene. Contents of the invention [0003] In view of this, the object of the present invention is to provide a pipe e...
