Description

Shuttle blade device for automobile painting workshop

technical field

The utility model relates to a vane device, in particular to a shuttle-type vane device for an automobile painting workshop.

Background technique

Air volume regulating valve is an indispensable central air-conditioning terminal fitting in ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in air conditioning and ventilation system pipes to adjust the air volume of branch pipes, and can also be used for fresh air and return air Wind mixing adjustment. There are also a certain number of air volume control valves used in the ventilation system of automobile painting workshops. Most of the foreign air volume control valves use aluminum profile blades, which are relatively expensive. Domestic air volume control valves are generally straight blades folded from plates. Reinforcing ribs, but the strength of the blades is not ideal. At the same time, due to the high positive wind pressure when the straight blades are switched, it is easy to cause the blades to vibrate or be damaged.
