摘要

This invention relates to an arrangement for sealing a closed chamber in which equipment is to be replaced and especially to a chamber in which equipment is to be replaced while the chamber is to be maintained closed. The arrangement includes a channel filled with a fluid, such as water, and a skirt arranged to extend into the fluid to form the seal. As the skirt extends down into the liquid, a portal space is formed at the opening in the chamber and the opening preferably includes a gate for closing the chamber from the portal space and the outside.
