ABSTRACT:
The locking valve apparatus includes a valve housing containing a rotatable cylinder lock with a keyway extending into the cylinder from one end and with a stationary cylindrical member of the valve housing encircling this rotatable cylinder. An alignment element on the outside of this stationary cylindrical member is adapted to position, align and guide a removable handle for the valve. This removable handle includes a sleeve defining a socket which is adapted to nest over the stationary cylindrical member of the valve housing when the handle is engaged for operating the valve. A key is located inside of this sleeve socket, being adjustably secured therein, and the socket is provided with a slot, which the user of the handle must align with the alignment element, otherwise the handle cannot be positioned on the valve housing. Accordingly, when the handle socket is placed on the valve housing with the slot being slid over the alignment element, the key becomes properly positioned for entry into the keyway and the handle becomes properly positioned for operating the locking valve mechanism. Furthermore, the interior end of this slot connects with a second arcuate slot adapted to receive the alignment element for permitting the handle to be turned relative to the valve housing only when the socket has been fully seated, thereby protecting the key itself from being twisted until is has been fully inserted into the keyway.
