Abstract
A valve locking system for safely and economically locking out control valves. The valve locking system includes a valve locking assembly for preventing manipulation of a valve including a rotating handle. The handle includes at least one aperture extending through the handle. The assembly includes a brace designed for coupling around a neck of the valve such that the brace is prevented from rotating around the neck of the valve. A cable includes a first end loop and a second end loop. The first end loop is coupled to the brace. The second end of the cable is insertable through the aperture in the handle. A locking member for coupling the first end loop to the second end loop such that the cable ties the handle to the brace whereby the handle is prevented from being rotated.
Claims15
A valve locking assembly for preventing manipulation of a valve having a rotating handle, the handle having at least one aperture extending through the handle, the assembly comprising:
- a brace adapted for coupling around a neck of the valve such that said brace is prevented from rotating around the neck of the valve;
- a cable having a first end loop and a second end loop, said first end loop being coupled to said brace;
- wherein said second end of said cable is insertable through the aperture in the handle;
- a locking member for coupling said first end loop to said second end loop such that said cable ties the handle to said brace whereby the handle is prevented from being rotated;
- said brace having a slot extending inwardly from an edge of said brace, said slot being adapted for engaging a protrusion extending outwardly from the neck of the valve whereby said brace is prevented from rotating around the neck of the valve when said slot engages the protrusion.
A valve locking assembly for preventing manipulation of a valve having a rotating handle, the handle having at least one aperture extending through the handle, the assembly comprising:
- a brace adapted for coupling around a neck of the valve such that said brace is prevented from rotating around the neck of the valve;
- a cable having a first end loop and a second end loop, said first end loop being coupled to said brace;
- wherein said second end of said cable is insertable through the aperture in the handle;
- a locking member for coupling said first end loop to said second end loop such that said cable ties the handle to said brace whereby the handle is prevented from being rotated;
- said brace having a medial ring portion adapted for engaging the neck of the valve;
- said brace having a pair of ends couplable to each other to close said medial ring portion around the neck of the valve;
- and
- a distal ring portion adapted for extending outwardly from the neck of the valve when said brace is coupled to the neck of the valve.
A valve locking assembly comprising:
- a valve having a handle, said handle having at least one aperture extending through said handle;
- said valve having an opening passing orthogonally through a medial portion of a neck of said valve for forming a generally O-shaped neck portion;
- a cable having a first end loop and a second end loop, said first end loop being coupled to said neck portion of said valve;
- wherein said second end of said cable is insertable through the aperture in said handle;
- a locking member for coupling said first end loop to said second end loop such that said cable ties said handle to said neck portion of said valve whereby said handle is prevented from being rotated.
A valve locking assembly for preventing manipulation of a valve having a rotating handle, the handle having at least one aperture extending through the handle, the assembly comprising:
- a brace adapted for coupling around a neck of the valve such that said brace is prevented from rotating around the neck of the valve;
- a cable having a first end loop and a second end loop, said first end loop being coupled to said brace;
- wherein said second end of said cable is insertable through the aperture in the handle;
- a locking member for coupling said first end loop to said second end loop such that said cable ties the handle to said brace whereby the handle is prevented from being rotated;
- said locking member including a tag extending from said locking member for providing a visual indicator that the valve is locked out from use;
- said brace having a slot extending inwardly from an edge of said brace, said slot being adapted for engaging a protrusion extending outwardly from the neck of the valve whereby said brace is prevented from rotating around the neck of the valve when said slot engages the protrusion;
- a first end of said cable being clamped to an interior portion of said cable proximate said first end to form said first end loop;
- a second end of said cable being clamped to an interior portion of said cable proximate said second end to form said second end loop;
- said brace having a medial ring portion adapted for engaging the neck of the valve;
- said brace having a pair of ends couplable to each other to close said medial ring portion around the neck of the valve;
- a distal ring portion adapted for extending outwardly from the neck of the valve when said brace is coupled to the neck of the valve;
- a cable aperture extending through a wall of said distal ring portion, said cable passing through said cable aperture whereby said cable is coupled to said distal ring portion of said brace;
- and
- said slot being located in a wall of said medial ring portion of said brace.
