An apparatus for inhibiting combustible fluid flowing through a conduit to a fire comprises a body (1) through which combustible fluid must flow before entering the conduit. The body (1) has an inlet (2) and an outlet (3). A nozzle (8) faces the inlet (2) of the body (1) and is disposed proximate the tapered end of a generally conical diffuser (4). …<??>If a fire breakes out in the conduit helium or other extinguishing fluid is released from a pressurized cylinder into the body (1) through nozzle (8). The helium travels towards the inlet (2) and is diffused across the entire cross-section of the body (1) as it hits the tapered sides of the generally conical diffuser (4). The helium forms a blanket which inhibits further combustible gas entering the conduit whilst at the same time purging the conduit. |
