Abstract
The invention discloses a combined ventilation door used for control over pipeline medium flow. The combined ventilation door comprises a framework, ventilation plates, a drive shaft, a driven shaft, and connecting mechanisms arranged between the drive shaft and the driven shaft. The framework comprises a frame, a top frame, a bottom frame and a middle beam, and is a pair of square frame bodies spliced from steel channels. The middle beam is located between the pair of square frame bodies. The drive shaft and the driven shaft penetrate through fixing holes in the frame to be fixed to the corresponding ventilation plates located in the square frame bodies. The connecting rod mechanism is arranged on the outer sides of the square frame bodies and connected with the drive shaft and the driven shaft. Servo motors on the corresponding connecting rod mechanisms are arranged at the two ends of the drive shaft correspondingly. Under driving of the servo motors, the drive shaft rotates, the connecting rod mechanisms drive the driven shaft to move reversely, and accordingly the ventilation plates are driven to be opened or closed. The combined ventilation door provided by the invention is reasonable in structure; the ventilation door is partitioned, and opening and closing of the ventilation plates are precisely controlled so as to control the flow of media flowing through the pipeline ventilation door; and the combined ventilation door has the advantage of easy operation and low cost.
