Description

Air volume regulating valve for purification equipment

technical field

The utility model relates to the technical field of air volume regulating valves, in particular to an air volume regulating valve used for purification equipment.

Background technique

In the automatic control of modern factories, regulating valves play a very important role. The production of these factories depends on the correct distribution and control of the flowing medium. Whether these controls are energy exchange, pressure reduction or simple container feeding, Some final control components are required to complete. The regulating valve plays the role of variable resistance in the pipeline. The air volume regulating valve is a common component in the purification equipment, which can ensure the normal operation of the purification equipment. , through the driving device to drive a connecting rod and fan blades to rotate, and adjust the opening and closing angle of the fan blades to adjust the air volume of the purification equipment. It is more troublesome and requires a lot of space for the fan blades to rotate. In order to prevent the dust and impurities inside the pipeline from entering the external environment through the regulating valve, the purification equipment usually installs a filter inside the regulating valve. After a long time of use, the surface of the filter will become dirty A large amount of dust and impurities are collected.
