I. System Introduction
This experimental system is divided into two parts: automatic sprinkler fire extinguishing system, fire hydrant system and fire alarm linkage control center, as shown in the figure:
1) The fire hydrant system is arranged as a temporary high-pressure system, which consists of a low-level fire water tank, a roof fire water tank, a fire water pump, a pressure-stabilizing and boosting device, a fire hydrant box, a water hose, a water gun, etc. It can demonstrate the basic composition of the fire hydrant system and the startup and operation principle of the system when a fire occurs;
2) The automatic sprinkler fire extinguishing system and the fire hydrant system share the low-level fire water tank and the roof fire water tank, and are composed of a fire water pump, a pressure-stabilizing and boosting device, an *r pump, a wet alarm valve, a dry alarm valve, a deluge alarm valve, a pre-action alarm valve, a water flow indicator, a nozzle, and a terminal water test device to form a complete automatic sprinkler fire extinguishing system, which can demonstrate the composition and working principle of the wet automatic sprinkler, dry, deluge, and pre-action fire extinguishing systems.
3) The fire alarm linkage control center realizes the fire alarm detector to automatically control the start and stop of the fire pump and the pressure switch, water flow indicator and other actions to link the fire alarm and control the start and stop of the fire pump.
2. System module combination scheme The fire hydrant of
this building fire demonstration system is used together with the part before the alarm valve of the automatic sprinkler fire extinguishing system. The part after the alarm valve can be divided into a fire hydrant fire extinguishing system and a wet automatic sprinkler fire extinguishing system. The automatic sprinkler fire extinguishing system can also be made into a dry automatic sprinkler fire extinguishing system, a pre-action system automatic sprinkler fire extinguishing system, a water spray type automatic sprinkler fire extinguishing system, and a water curt*n type automatic sprinkler fire extinguishing system according to requirements. The specific module combination scheme is shown in the table below.
