摘要 |
A leaking block valve isolation tool for insertion through a vent duct and blocking valve of a gas flow duct. The isolation tool includes an outer tube (20) having proximal and distal ends, the outer tube having a diameter sized to extend through the vent duct (14) and blocking valve. An inner tube (22) having proximal and distal ends is arranged coaxially with and movable within the outer tube (20). An inflatable balloon (24) is attached to the distal end of the inner tube, wherein the isolation tool outer tube is insertable through the vent duct (14) to an opening in the gas flow duct. The inner tube is slidably insertable through the outer tube until the balloon is situated within a bore formed through the gas flow duct and is inflatable therein to block any gas leak through the gas flow duct. |
