#CMT# #/CMT# The sprinkler has a joint armature (A) e.g. ball joint, which is positioned between a sprinkler unit (1) and a fire water pipe connection (6) and generates an alarm during position change by trigger contacts. The sprinkler unit is connected to a sprinkler piping system at a specified position in a system area. The fire water pipe connection staying under primary pressure is connected to a housing of the armature over recesses. Amount of fire water discharged from the housing over cross-sections of an inner contour and over housing openings during the position change is determined. #CMT#USE : #/CMT# Safety sprinkler for a fire extinguishing system that is utilized in a building or installation and in a fork-lift truck. #CMT#ADVANTAGE : #/CMT# The joint armature is positioned between the sprinkler unit and the fire water pipe connection, thus enabling compensation of kinetic energy that acts on the normally positioned sprinkler during improper handling with goods, tools or furniture, preventing damage caused by mechanical energy with trigger contacts in a trigger direction, and avoiding relevant water damage caused by damaged sprinkler. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a safety sprinkler in a normal position. A : Joint armature 1 : Sprinkler unit 2 : Rotatable body 6 : Fire water pipe connection 8 : Water flow rate. |
