Abstract

The invention provides a three-way connector with a flow guide structure. The three-way connector comprises a three-way main body and a center flow guide structure and outlet flow guide structures which are arranged in the three-way main body; and the three-way main body comprises a branch pipe and a main pipe connected to the branch pipe, the center flow guide structure is arranged on the portion, right facing a flow dividing opening of the main pipe, of the inner wall of the branch pipe, and the two ends of the branch pipe are provided with the outlet flow guide structures respectively. The three-way connector is connected with an upstream pipeline and a downstream pipeline through an inlet end face flange and an outlet end face flange, installation and use are convenient, the center flow guide structure and the outlet flow guide structures are arranged in the three-way main body, the flow disturbing effect can be effectively achieved, a flow field of solid-containing fluid flowing through the three-way connector is changed, the flow characteristic is effectively improved, erosive wear is reduced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of pipeline protection design, and in particular relates to a tee joint with a diversion structure. Background technique [0002] Because pipeline transportation has the advantages of simple structure and good economy, it has been widely used in the field of oil and gas transportation and petrochemical industry. It is difficult to avoid solid particles in pipelines that transport gas, liquid or gas-liquid mixture. When the solid-containing fluid flows to some special positions of the pipeline, such as elbows and tees, the fluid flow direction changes sharply, resulting in changes in the pressure and flow velocity of the fluid-solid two-phase inside and outside the pipeline, especially near the inner and outer walls. The particles impact the inner wall of the pipe under the action of inertia, and will form erosion wear under long-term work. For the three-way joint, the junction of the three pipes will be imp...
