Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve cleaning, in particular to a pneumatic butterfly valve cleaning device. Background Art

[0002] Pneumatic butterfly valves are composed of pneumatic actuators and butterfly valves. Pneumatic butterfly valves use a circular butterfly plate that rotates with the valve stem to open and close the valves, and are mainly used as shut-off valves.

[0003] After long-term use, the existing pneumatic butterfly valve has a lot of impurities in the fluid. When it flows through the valve body cavity, the impurities in the fluid will be retained in the valve body cavity. The long-term accumulation of impurities will affect the closure of the valve plate, so the butterfly valve needs to be cleaned regularly. When cleaning the butterfly valve, the butterfly valve is disassembled, and then the valve plate and valve seat are cleaned separately. When cleaning the valve seat cavity, the staff currently use a handheld cleaning brush with water to scrub. The manual scrubbing of the staff is inefficient and there are areas where cleaning is missed, resulting in poor cleaning effect. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content
