Description

Technical Field

[0001] The utility model relates to the technical field of flue elbows, in particular to a flue elbow for a flue guide plate. Background Art

[0002] When the fluid passes through the pipe elbow, eddy currents will be formed. The eddy currents will reduce the fluid flow rate and increase the transmission energy consumption. At the same time, the fluid has a great impact on the elbow, and the elbow is easily damaged. Adding a guide plate at the elbow can avoid the generation of eddy currents, increase the fluid flow rate at the elbow, and reduce energy consumption.
