1、 Terminology
1-1 fire separation water curtain
Instead, it is composed of open sprinkler or water curtain sprinkler, deluge alarm valve group or temperature sensitive deluge alarm valve, etc. in case of fire, it is a water curtain system that forms a water wall or water curtain by dense spraying.
1-1.1 protective cooling water curtain
Instead, it is composed of water curtain sprinkler, deluge alarm valve group or temperature sensing deluge alarm valve, which is used to cool fire-proof rolling curtain, fire-proof glass wall and other fire separation facilities in case of fire.
1-1.2 protective cooling system
Instead, it is composed of closed sprinkler, wet alarm valve group, etc., which is used to cool the fire separation facilities such as fire rolling shutter and fire glass wall in case of fire.
The fire separation water curtain and the protective cooling water curtain are both water curtain systems, which are open systems. The protective cooling system is a wet system, which is a closed system.
The fireproof cooling water curtain and protective cooling system are used to cool the fireproof rolling curtain and fireproof glass wall; Fire separation water curtain is used to replace fire rolling curtain or fire glass wall for fire separation.
2、 System requirements
Protective cooling water curtain shall indirectly spray water to the protected object; Fire separation water curtain should not be used for sizes exceeding 15m (width) × 8m (high) opening (except stage opening).
The scope of application of the fire separation water curtain is limited. The purpose is never to recommend the use of the fire separation water curtain as a fire separation facility within the fire compartment. The practice that a large amount of stored fire water is used for active fire prevention because it is not necessary to put out the fire immediately does not conform to the principle that active fire fighting should be carried out in case of fire.
