When the ball 1 is worn and can no longer fit tightly with the sealing seat 6, the locking lever 26 is pulled out, causing the protrusion 21 to be pulled out from the groove 24. The ball 1 is then removed and replaced, and placed inside the ball valve 4. Block 21 is inserted into the groove 24. Under the action of the retaining ring 22 and the annular groove, the protrusion 21 can be locked inside the groove 24, thereby achieving the function of fixation. Under the action of the limiting rod 23 and the circular groove 25, the protrusion 21 will not rotate inside the groove 24, thereby achieving the function of limiting. When the retaining ring 22 is inserted into the annular groove, under the action of the first spring 27, the retaining rod 26 is inserted into the protrusion 21 in a self-locking state, thereby achieving the function of fixation, thus achieving the function of replacing ball 1.
