Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] See attached Figure 1-4 : The airflow regulating device includes a first pipe 1 , a second pipe 2 , a blade 3 , a blade body 5 , a diversion arc 6 , and a diversion groove 7 .
[0019] The first pipeline 1 and the second pipeline 2 are vertically arranged, and there is a diagonal line 4 at the corner where they are connected, and a row of multiple blades 3 is arranged along the diagonal line 4, and the plurality of blades 3 are located between the first pipeline 1 and the second pipeline. In the corner where the pipes 2 are connected, a row of multiple blades 3 is arranged vertically to the diagonal line 4 .
[0020] The angle a=15-20° between the diagonal line 4 and the horizontal line is preferably 18°; the angle b=15-20° between the blade 3 and the vertical line is preferably 18°; each blade of a row of multiple blades 3 There are different dista...

The invention relates to an airflow adjusting device for a ventilation pipeline system. The airflow adjusting device for the ventilation pipeline system comprises a first pipeline (1), a second pipeline (2) and blades (3), wherein the first pipeline and the second pipeline are perpendicular, a diagonal line (4) is arranged at the connection corner of the first pipeline and the second pipeline, therow of blades (3) are arranged along the diagonal line, the multiple blades are located in the connection corner of the first pipeline and the second pipeline, the row of blades (3) are perpendicularto the diagonal line, and the included angle between the diagonal line and the horizontal line is alpha. The airflow adjusting device for the ventilation pipeline system is characterized in that therow of blades (3) are in bilateral symmetry with respect to the middle blade and are spaced at different intervals, the intervals of the blades in the middle area are large, and the intervals of the blades in the areas on the two sides is small. The turbulence flow at the corner can be reduced, and the flow of the middle are is increased; and a good flow guide effect is achieved, the vortex of thedownstream end of the blades is reduced, and airflow uniformity is improved.
Description
technical field [0001] The invention relates to the field of ventilation systems, in particular to an airflow regulating device for a ventilation pipeline system. Background technique [0002] The corner of the ventilation duct system usually adopts an airflow adjustment device, such as arranging guide vanes. The existing airflow adjustment device has the problems of turbulent airflow at the corner, small flow rate, and eddy current at the downstream end of the blade. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an airflow regulating device for the ventilation duct system, which can reduce the turbulent flow at the corner and increase the flow rate in the middle area; The vortex at the downstream end of the blade improves the uniformity of the airflow. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An airflow regulati...
