Adjustable uniform-air distributing device of air system

Abstract

The invention discloses an adjustable uniform-air distributing device of an air system. The adjustable uniform-air distributing device comprises a central pipe and guiding pipelines. The central pipe is serially connected in a main air pipe of the air system, and at least one connecting port is reserved on the wall of the central pipe. The guiding pipelines are connected with branch air pipes and comprise outlet sections and inlet sections, wherein the inlet sections of the guiding pipelines penetrate the connecting ports to extend into the central pipe, the inlet direction of air inlets of the guiding pipelines are consistent with that of the main air pipe of the air system; movable guiding plates are arranged at openings of the walls of the guiding pipelines, the front ends of the movable guiding plates are hinged with the walls of the inlet sections via hinge points, the rear end of the movable guiding plates are connected with adjusting pull rods which move in reciprocation along axial perpendicular direction of the central pipe, the adjusting pull rods penetrate holes on the outer wall of the central pipe to extend outside the central pipe, and positioning devices for fixing the adjusting pull rods on the outer wall are arranged between the adjusting pull rods and the holes on the outer wall of the central pipe. The adjustable uniform-air distributing device of the air system is simple to operate, high in adjusting precision, convenient to process and mount and low in cost, and has good application prospect and social benefits.

Description

technical field [0001] The invention relates to the technical field of ventilation and air conditioning, in particular to an easily adjustable and uniform air distribution device for an air system. Background technique [0002] At present, in all-air air conditioning systems and ventilation systems at home and abroad, many air system branch ducts and air outlets are usually set to meet the requirements of uniform air supply in large spaces, so the air volume of each air system branch air duct and air outlets needs to be adjusted. In order to meet the needs of air volume adjustment, it is usually necessary to install an air volume regulating valve on the branch air pipe of the air system, or set a baffle between the branch air pipe of the air system and the main air pipe of the air system to adjust the air volume. Some also directly adjust the air volume by changing the area of ​​the air supply and return air outlets. These methods often have disadvantages such as difficulty...
