Description

Technical Field

[0001] The utility model relates to the field of air valves, in particular to an air valve which is convenient for controlling wind direction. Background Art

[0002] The air volume regulating valve, also known as the wind valve, is an indispensable central air-conditioning terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. The wind valve is generally installed on the pipeline to adjust the flow rate of the gas medium or cut off the gas medium. It can also be used for the mixing adjustment of fresh air and return air.

[0003] China Publication No.: CN213451858U discloses a wind valve for controlling wind direction, including a T-shaped wind duct, a main valve and an auxiliary valve. The main valve and the auxiliary valve are both provided with two leaves, and the two main valves are arranged side by side in the front of the interior of the T-shaped wind duct, and the two auxiliary valves are respectively arranged on both sides of the rear of the interior of the T-shaped wind duct. A motor is installed on the upper surface of the front of the T-shaped wind duct. The device of the application makes the main valve and the auxiliary valve rotate synchronously through the cooperation of the motor, the first bevel gear, the second bevel gear, the third bevel gear, the fourth bevel gear, the connecting rod, the rotating shaft, the pulley and the belt. The opening and closing angle of the main valve is used to control the wind volume, and the auxiliary valve rotates to the left or right to control the wind direction to the left or right. The main valve and the auxiliary valve rotate simultaneously, so that the wind volume and wind direction inside the wind valve are easy to control, and it is convenient to use. However, in this application, the main valve and the auxiliary valve are opened and closed synchronously by an electric motor, which makes it inconvenient to adjust only one of the valves. In addition, this application does not provide a positioning component for the main valve and the auxiliary valve, which makes it easy for the main valve and the auxiliary valve to rotate automatically under a large air volume, resulting in failure of air volume and wind direction control, and easily causing damage to the motor.
