when the ball valve body is closed and needs to be closed, the first rotating plate 26 and the second rotating plate 28 are started to rotate towards the side close to the elliptic cylinder 25, the controller controls the air pump outside the connecting pipe 1 to pump outside air, the outside air is conveyed into the conveying channel through the pipeline, then the outside air is conveyed into the air cavity 30 through the conveying channel, the hand controller controls the electromagnetic valve in the pipeline communicated with the air bag 31 to be opened, air in the air cavity 30 is conveyed into the air bag 31 through the pipeline, the air bag 31 is gradually expanded, the expanded air bag 31 is contacted with the second rotating plate 28, the second rotating plate 28 is contacted with the air bag 31, the second rotating plate 28 is matched with the air bag 31, the conical pipe 21 is blocked by the air bag 31, the conical pipe 21 is isolated from the ball valve body, and the impact of water acts on the second rotating plate 28 and the air bag 31, and the force generated by partial water hammer effect is further counteracted.
