AI Technical Summary
Existing ball valves are prone to jamming during use, which affects normal operation and poses safety risks. They also have poor operational stability, complex structure, and are inconvenient to maintain.
A detachable filter device, including a filter element and a plug, is installed upstream of the valve body. The rotation trajectory of the ball core is stabilized by an annular groove and an elastic positioning device to prevent jamming caused by solid impurities, and the plug is prevented from falling out by the elastic positioning device.
It effectively reduces the ball core rotation obstruction caused by solid impurities, improves the stability and safety of the ball valve, facilitates maintenance, and reduces the failure rate.
