Especially in critical or hazardous environments, such as chemical production and high-pressure gas transportation, misoperation of ball valves can have serious consequences.
[0003] To address this issue, some ball valve designs with anti-accidental operation features have emerged on the market. These designs typically prevent accidental rotation of the handle by adding an extra locking mechanism or limiting device. However, these designs are often complex in structure, inconvenient to operate, and may affect the normal use of the ball valve in certain situations.
