INFLATABLE FLUID CONDUIT PLUG

摘要

An inflatable conduit plug is used to seal a conduit such as a floor drain or an air vent. The conduit plug includes a shroud that is removably sealed within the conduit so that fluids pass through the shroud opening. Axially disposed within the shroud is an inflatable bladder adapted for closing the shroud opening. The inflatable bladder is inflated by an inflation signal generated by a controller upon receipt of a contamination signal received from a remote contamination detector. The plug operates in a wireless environment and can be controlled remotely. The plug can also be adapted for diverting contamination away from sensitive lands and storm drains.
