Abstract
A fire suppression sprinkler device 100 includes a sprinkler bulb 140, a nozzle manifold 160, and a conduit 190 for supplying fluid to the nozzle manifold 160. The sprinkler device 100 is arranged so that breakage of the sprinkler bulb 140 permits fluid communication from the interior of the conduit 180 to the nozzle manifold 160. The nozzle manifold 160 is disposed about the conduit 190.
Claims18
A fire suppression sprinkler device comprising:
- a sprinkler bulb;
- a nozzle manifold;
- and
- a conduit for supplying fluid to the nozzle manifold;
- wherein the sprinkler device is arranged so that fluid may flow through the sprinkler device while the sprinkler bulb is intact and so that breakage of the sprinkler bulb permits fluid communication from the interior of the conduit to the nozzle manifold;
- wherein the sprinkler device is arranged so that the conduit is connectable to supply pipes at opposite ends thereof;
- wherein the nozzle manifold is disposed about the conduit;
- wherein the sprinkler bulb is positioned vertically upwards above the conduit;
- and
- wherein the nozzle manifold comprises a plurality of nozzles, at least one nozzle being configured to eject fluid downwards and allow fluid in the nozzle manifold to drain under gravity.

A method of fire suppression comprising:
- flowing fluid through a sprinkler device while a sprinkler bulb of the sprinkler device is intact;
- and
- in the event of breakage of the sprinkler bulb, supplying fire suppression fluid from an interior of a conduit to a distribution volume about the conduit, and further comprising supplying the fluid from the distribution volume to a nozzle of a nozzle manifold disposed about the conduit,
- wherein the sprinkler device is arranged so that the conduit is connectable to supply pipes at opposite ends thereof;
- wherein the sprinkler bulb is positioned vertically upwards above the conduit;
- and
- wherein the nozzle manifold comprises a plurality of nozzles, at least one nozzle being configured to eject fluid downwards and allow fluid in the nozzle manifold to drain under gravity.
