Rotating the handle 507 drives the square column 402, the valve stem 401 and the insert block 404 to rotate together through the square groove 508.

[0027] The usage and advantages of this utility model: The working process of this easy-to-open and close ball valve assembly is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the ball valve needs to be opened or closed, the operator holds the handle 507 and lifts it upwards, causing the locking block 505 to move from the locking groove 504 into the arc-shaped slide groove 503. Rotating the handle 507 drives the square column 402, valve stem 401, and insert block 404 to rotate together through the square groove 508. The insert block 404 drives the valve core 301 to rotate within the spherical cavity 202 through the groove 302. The rotation of the valve core 301 changes the alignment state between the flow channel 303 and the flow port 203, thereby realizing the flow on / off control. After rotating 90 degrees, pressing the handle 507 downwards causes the locking block 505 to move from the arc-shaped slide groove 503. The ball valve is locked in the locking slot 504. The operator can easily open and close the ball valve by simply lifting, rotating and pressing down the handle 507 without complicated tools or steps. At the same time, the locking mechanism prevents the valve stem 401 and valve core 301 from rotating accidentally due to external force or vibration. The valve stem 401 and valve core 301 are indirectly driven by the insert block 404. When the ball valve assembly needs maintenance or replacement of parts, the valve stem 401 can be easily removed, making it easier to access the valve core 301 and other internal parts. Convenient maintenance operations help to replace worn parts in a timely manner, thereby extending the service life of the entire ball valve assembly.
