Description

Technical Field

[0001] The invention relates to the technical field of pipe joints, and in particular to a three-way flow dividing joint with filtering function and easy cleaning. Background Art

[0002] During pipeline transportation, when the fluid containing solid particle impurities flows to some special positions of the pipeline, such as elbows and tees, the fluid flow direction changes dramatically, resulting in changes in the pressure and flow rate of the fluid-solid phases inside and outside the pipeline, especially near the inner and outer walls. At the same time, the solid particle impurities impact the inner wall of the pipeline under the action of inertia, which will cause erosion and wear under long-term operation. In addition, the internal structure of the existing three-way diverter joint is simple and cannot filter the fluid. The impurities after filtration are also not easy to clean, which can easily cause the three-way diverter joint to be blocked, affecting its use. Summary of the invention

[0003] The purpose of the present invention is to address the defects and shortcomings of the prior art and provide a three-way diverter joint with a reasonable design, easy use and easy-to-clean filtering function, which can filter the fluid during its circulation and can easily clean the filtered impurities after a period of time, thereby preventing blockage.

After filtration, the fluid is discharged through the discharge ports on both sides of the joint body, and the impurities in the fluid are retained on one side of the No. 1 filter plate and the No. 2 filter plate. After a period of time, the feed port position is blocked by the blocking mechanism, and at the same time, the No. 2 filter plate is driven to move to one side of the center of the joint body, so that the No. 1 filter plate and the fixed plate rotate with the shaft on the fixed plate as the axis, and at the same time, the blocking mechanism drives the limiting mechanism to rotate, so that the impurities fall from one side of the fixed plate into the collection box. When the collection box needs to be cleaned, the limiting mechanism is released to facilitate the removal of the collection box for cleaning.
