Abstract

The invention discloses a ventilation system adjustable drift diameter circle air door and a design method thereof; the ventilation system adjustable drift diameter circle air door comprises an air door pedestal (100), a movable plate (200), a rotary arm (220), a plurality of blades (300), a fixed plate (400), an adjusting handle (500), an adjusting box (600) and a seal cover plate (700); the features are that the adjusting box (600) is fixedly connected with the air door pedestal (100); the movable plate (200) is arranged in the air door pedestal; the rotary arm (220) on the movable plate (200) extends into the adjusting box (600); the blades (300) are evenly stacked on the movable plate (200). The ventilation system adjustable drift diameter circle air door can be applied to the ventilation system with high air quantity adjusting requirements, and the blades are staggered and stacked so as to prevent deformation and wearing, so the ventilation system adjustable drift diameter circle air door can work in long time with good reliability.

Description

technical field [0001] The invention discloses a circular damper with an adjustable diameter in a ventilation system and a design method thereof. Background technique [0002] The damper is widely used in industrial production and daily life to adjust the flow rate. Its main working principle is that when the air supply flows through the pipe equipped with a throttling damper, due to the local resistance of the damper, part of the energy loss occurs, so that the air behind the damper The fluid pressure is reduced; at the same time, the installation of dampers will change the characteristics of the corresponding outlet pipes and reduce the air supply volume after passing through the dampers. [0003] At present, the dampers used in the ventilation systems of industrial plants and buildings are all fixed calibers and cannot be adjusted. When the deviation from the required value of the corresponding working condition is within the controllable range, the problem will be ignore...
