A nozzle dam automatically latches on an annular ledge surrounding the nozzle opening. A pivotal latch arm on the dam, biased to the locked position is forced toward the unlocked position by a cam on the ledge as the nozzle is pressed on the ledge, and snaps into engagement with the ledge when the dam is fully seated over the opening. A bias arm may be operated by a wrench to pivot the latch arm toward the unlocked position until a detent locks the latch arm in the unlocked position.

Quick installation non-bolted nozzle dam system

In an enclosure of a heat exchanger that includes a wall having an opening for access to the enclosure and a nozzle for fluid flow through the wall, an articulate hoist for bringing an articulate manipulator into the enclosure is attached to the wall outside the opening. The lifting portion of the hoist, which is in the enclosure brings the manipulator into the enclosure. The manipulator which is is then attached to the wall outside the opening is adapted for reaching through the opening from inside the enclosure. A tool operator portion of the manipulator is adapted for engaging a nozzle dam for inserting the dam in the nozzle. One type of nozzle dam which the apparatus can install is one that falls within the description of a claim of U.S. Pat. No. 4,957,215.
