Fire extinguishing sprinkler system

摘要

The extinguisher system comprises a nozzle, attached to a water pipe, through which passes a rod attached at its other end to a piston, which causes withdrawal of the rod in the event of a fire by means of a sensor and explosive charge.The water pipe (2) has an outlet nozzle (3) attached, sealed by a rod (7a) and O-ring (14). A support housing (4) carries a cylinder and piston (6) with a fire detector (11), the piston (8) forming the remote end of the rod. An explosive material (10) above the piston creates a driving gas in the event of a fire, driving the piston, and hence the rod out of the nozzle, releasing water
