AI Technical Summary
Traditional tee fittings generate significant noise during use, mainly due to turbulence, eddies, and pipe wall vibration caused by sudden changes in fluid direction or velocity.
Design a Y-type noise reduction tee fitting with an inlet section that is curved in opposite directions and a guide plate is installed on the inner wall of the lower side of the inlet section. The guide plate is in the same direction as the inlet section and is triangular in shape, used to guide and split the fluid.
By reducing abrupt changes in fluid direction or velocity, turbulence and eddies are reduced, resulting in significant noise reduction. Pressure loss is only 27% of that of traditional T-type tee fittings, and manufacturing is more convenient.
