Abstract
A storage tank hatch isolation system for a storage tank having a vertical riser attached to a top of the storage tank and having a cover with an aperture, a connecting member extending from a side of the vertical riser, a distal end of the connecting member being attached to a tank hatch, and a valve assembly assessable through the aperture in the cover, the valve assembly configured to be moved from an open position in which flow through the vertical riser to the connecting member is not obstructed, and a closed position in which flow through the vertical riser to the connecting member is obstructed.

A storage tank hatch isolation system for a storage tank, comprising:
- a vertical riser attached to a top of the storage tank and having a cover with an aperture;
- a connecting member extending from a side of the vertical riser, a distal end of the connecting member being attached to a tank hatch;
- and
- a valve assembly assessable through the aperture in the cover, the valve assembly configured to be moved from an open position in which flow through the vertical riser to the connecting member is not obstructed, and a closed position in which flow through the vertical riser to the connecting member is obstructed.
A system configured to isolate a tank hatch from a storage tank, the system comprising:
- a vertical riser configured to be attached to a top of the storage tank and having a cover with an aperture;
- a connecting member configured to extend between the vertical riser and the tank hatch;
- a valve assembly assessable through the aperture;
- and
- a lever assembly configured to move the valve assembly from an open position in which the vertical riser is not obstructed at a position equal to or below a connection to the connecting member, and a closed position in which the vertical riser is obstructed at the position equal to or below the connection to the connecting member to isolate the storage tank.
A storage tank hatch isolation system, comprising:
- a vertical riser attached to a top of a storage tank and having a cover with an aperture;
- a connecting member extending between the vertical riser and a tank hatch;
- and
- a valve assembly, comprising:
- a stem extending through the aperture in the cover;
- a valve plate attached to the stem;
- a valve seat attached to the vertical riser at a position equal to or below an opening to the connecting member;
- wherein the valve plate is held within the vertical riser at a position equal to or above the opening to the connecting member, and a closed position in which the valve plate is on the valve seat to isolate the storage tank.
