ABSTRACT:
This invention relates to a conduit that is at least partially encased within a containment housing. The containment housing provides structure for containment of fluids from a leaking or totally failed conduit and for automatically shutting off the flow of fluid through the leaking conduit. More particularly, the apparatus comprises at least one conduit that is at least partially received within a containment housing. A valve is attached to the conduit so that it is in fluid flow relationship with the conduit. The valve is biased toward a closed position, but is held in the open position by a release located within the containment chamber, defined as the space between the exterior of the conduit and the interior of the containment housing. When a predetermined fluid leaks from the conduit into the containment chamber the block expands and thereby operatively engages the release so that the valve moves to the closed position blocking the flow of fluid through the conduit.
