Classification of water mist extinguishing system

1, according to the use of pressure classification can be divided into high, medium and low pressure systems

① high-pressure system

Refers to the system of pipe network can withstand greater pressure 3.5Mpa or water mist extinguishing system.

② medium pressure systems

Refers to the system of pipe network can withstand greater but less than 3.5Mpa 1.2Mpa pressure water mist system.

③ low pressure system

Refers to the system of pipe network can withstand 1.2Mpa or smaller pressure water mist extinguishing system.

2, by the use of the media can be divided into single-phase and two-phase fluid medium system fluid medium system. Single-phase fluid media system medium is water.

Two-phase system is generally a dielectric fluid medium is water, another medium is air, an inert gas such as nitrogen.

3, can be divided into categories according to application mode total flooding fire extinguishing systems and local application fire fighting systems.

① total flooding fire extinguishing system for fighting fires in enclosed spaces.

② local application fire fighting systems for relatively large space enclosed within the specific protected object fires.

4, can be divided into categories according to product mix bottle group type, pump-and bottle-type group and pump combination

① cylinders from the storage container type, gas storage containers, one-way valve, manifold, pressure relief safety devices, control valves, nozzles, pipes, pipe fittings and pressure switches, backpack sprayers detectors, alarm controller and other components of automatic fire extinguishing system. The system pressure standby state storage containers, pressure gas containers.

② pump from the tank, filters, pumps, manifolds, pressure relief safety devices, control valves, sprinklers, pipes, pipe fittings and pressure switches, detectors, alarm controller and other components of the automatic fire extinguishing system. The system standby storage tank fire all the required amount of water.

③ cylinders and pump knot full ceremony by storage tanks, filters, pumps, water containers, gas containers, check valves, manifolds, pressure relief safety devices, control valves,bottle sprayer sprinklers, pipes, pipe fittings and pressure switches, detectors, alarm controller and other components of the automatic fire extinguishing system.

5, according to the specific requirements of protected sites can be designed as a unit independent systems and combined distribution system

① unit stand-alone system is protected by a fire extinguishing system, a protection zone or the protection of objects.

② combined distribution system is protected with a fire-extinguishing system of two or more of the protection zone, or the protected object.
