Zusammenfassung:A ball valve of the present invention allows a locking member to be installed on a ball and enables the locking member to block the rotation of the ball until a lock release key changes the locked state of the locking member into an unlocked state so as to rotate the handle of the valve to prevent a flow path from being opened. Accordingly, the locking member is not changed to the unlocked state until the lock release key is inserted into and mounted on the handle. Therefore, the handle can be randomly operated in a state where the valve is not in use so that the flow path of the valve can be prevented from being opened. 본 발명의 볼 밸브는, 볼 상에 락킹부재를 설치하고, 잠금해제키가 락킹부재의 락킹 상태를 언락 상태로 변경하기 전에는 락킹부재가 볼의 회전을 막아 밸브의 핸들을 회전시켜 유로가 개방되는 것을 방지하여 핸들에 잠금해제키가 삽입되어 장착되기 전까지 락킹부재가 언락 상태로 상태가 변경되지 않는다. 따라서, 밸브를 사용하지 않은 상태에서 임의로 핸들이 조작되어 밸브의 유로가 개방되는 것을 방지할 수 있다.
