Claims

[Scope of Claim for Utility Model Registration] (1) A ball having a through hole is airtightly and rotatably housed in a valve chamber of a valve body having a through hole connected to a pipeline through a seat, In a ball valve with an existing configuration in which the valve is opened and closed by rotating a spindle connected to the handle at a set angle, a lock bolt is screwed into a part of the handle so that it can be screwed in vertically up and down directions, and the lock bolt When the lock bolt is screwed back up, the valve can be opened and closed using the handle. If you try to turn the handle with the lock bolt screwed down, the lower end of the lock bolt will hit the outer surface of the valve body, making it impossible to turn the handle. In other words, a ball valve with a locking mechanism, characterized in that the valve is configured to be locked in an open or closed state. (2) The ball valve with a locking mechanism as set forth in claim 1 of the utility model registration claim, wherein an engagement structure is formed on the head of the locking bolt for screwing the locking bolt forward and backward with a simple special tool. (3) The head and lower end of the lock bolt are formed to have a larger diameter than the threaded part screwed into the handle, so that the lock bolt does not slip out above or below the handle when screwing forward or backward. A ball valve with a locking mechanism according to claim 1 of the registered utility model claim. (4) The head of the locking bolt is located in the bolt insertion hole of the handle, and the top surface of the locking bolt is located approximately at the top of the handle when the locking bolt is screwed back and up. Ball valve with locking mechanism as described in . (5) The ball valve with a locking mechanism according to claim 1, wherein a nut for attaching the handle to the spindle is fitted into a recessed hole in the handle.
