[0002] Butterfly valves are commonly used control components in industrial pipeline systems and are widely used in water supply and drainage, petrochemical, and power industries. During long-term use, the valve body is prone to rust formation due to media corrosion and oxidation. This rust layer not only affects the valve's sealing performance, increasing the risk of leakage, but also increases the valve's opening and closing resistance, reduces its service life, and may even cause pipeline system failures.

[0003] A search revealed existing technology (application number: CN212578315U), which describes "a rust removal device for a butterfly valve cavity." This utility model uses a micro motor to drive a rotating shaft to drive a grinding wheel for rust removal. Simultaneously, a micro water pump sprays rust removal liquid from a storage bottle through a hose, a distribution pipe, and a nozzle to assist in rust removal. Finally, a brush head cleans the valve, achieving a rust removal method of grinding, spraying, and cleaning. However, this device has drawbacks such as low automation, reliance on manual rust removal operation, and inability to achieve stable clamping of the butterfly valve and efficient all-round rust removal.
