Electric square air door

Abstract

The invention discloses an electric square air door. The electric square air door comprises a square framework, wherein a fixed pressure block is arranged at each of corners of the square framework; a plurality of air baffle plates capable of turning over are arranged in the frame of the square framework; the air baffle plates are parallel to one another; a control bar is further arranged on the square framework; a plurality of rollers are arranged on the control bar; the rollers are in one-to-one correspondence with the air baffle plates; a drive motor is further arranged on the square framework; the drive motor drives the rollers to rotate through the control bar while the rollers drive the air baffle plates to automatically turn over; the number of the air baffle plates and the rollers is not smaller than 10; the drive motor is a direct-current asynchronous motor; and the air baffle plates are made of elastic plastic. According to the electric square air door disclosed by the invention, the number of the air baffle plates is controlled to be greater than 10, and the air baffle plates are parallel to one another and are completely controlled by the rollers; and the area of each air baffle plate is relatively small, so that the air resistance, borne in a turnover process, of the corresponding air baffle plate is also small, and therefore, the requirements on a drive system are greatly reduced, the requirements on the drive motor and a drive shaft are especially reduced, and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a damper, more precisely, an electric square damper. Background technique [0002] The damper is a commonly used device in the air supply system. The electric damper is composed of an electric actuator and a damper. The adjustable electric damper can adjust the opening degree of the damper and control the size of the air volume. Control the size of the air volume. The two-position electric damper starts To the function of closing and opening, if there is a time requirement for opening and closing, the quick cut-off damper can be selected, and the whole time can be completed in 6 seconds or 3 seconds. The damper has a square damper and a round damper. [0003] The windshields of the commonly used electric square dampers generally have a relatively large area at present, and the number of windshields of a square damper is 3-4. Due to the large area of ​​the windshield, the motor needs to output larger power and output torque dur...

AI Technical Summary

Problems solved by technology

Due to the large area of ​​the windshield, the motor needs to output larger power and output torque during the process of driving the windshield to rotate, which not only has higher requirements on the motor, but also has higher strength on the driving shaft. requirements, higher manufacturing costs
