[0002] Butterfly valves are characterized by their simple structure, small size, light weight, low material consumption, compact installation dimensions, rapid opening and closing (90° reciprocating rotation), and low driving torque. The streamlined design of the butterfly plate minimizes fluid resistance loss, and the through-stem structure, after heat treatment, provides excellent comprehensive mechanical properties, corrosion resistance, and abrasion resistance. Furthermore, butterfly valves offer diverse connection methods, including flange connections, wafer connections, butt-welded connections, and lug wafer connections. They also offer a variety of actuation options, such as manual, worm gear drive, electric, pneumatic, hydraulic, and electro-hydraulic linkage, enabling remote control and automated operation.

[0003] Currently, most butterfly valves on the market have handles that are not easy to remove. Users may need to spend more time and effort to disassemble and reassemble the valves during maintenance, which not only reduces maintenance efficiency but may also prolong production line downtime and negatively impact production efficiency.
