Specifically, the pipe diameter of the pipe network is determined according to the maximum water consumption of each system by the traditional independent pipe network, and a general factory building with the building height not exceeding 50 meters and a high-rise matched building are taken as an example. The general factory building is usually leased in the later period, the production products and the process are not clear, and the fire control can not be accurately and qualitatively performed, so that a fire control system needs to reserve a proper allowance so as to be convenient for the operation of later-period lessees. Therefore, most general-purpose plants are generally designed according to two categories of fire hazard. The pipe diameter requirements of the independent pipe network are shown in table 1; the pipe diameters of the combined pipe networks are shown in Table 2, and the pipe diameters and the steel consumption of the independent pipe networks and the combined pipe networks are shown in Table 3.

As can be seen from tables 4 and 5, the head loss of the combined pipe network is smaller, the requirement on the lift of the water supply pump can be reduced, the power of the driving motor can be further reduced, and the later operation and maintenance cost is low.

Assuming that the most unfavorable path length of the garden pipe network is 500 meters, the local head loss is 10% of the head loss along the head, and after a water supply system with a combined pipe network is adopted, the water supply pump lift of the indoor fire hydrant system can be reduced by 6.6 meters, and the water supply pump lift of the automatic water spraying fire extinguishing system can be reduced by 25.6 meters. After the water supply system using the combined pipe network is adopted, the pipe diameter of the pipe network is large, the head loss is reduced, and the lift of the water supply pump can be reduced.

In conclusion, compared with the traditional fire-fighting water supply system, the water supply system provided by the utility model can save steel consumption of pipes by using the pipe network, can save space occupied by laying the pipe network, reduces excavation amount and backfill amount, and has better overall economy; the head loss of the pipeline can be reduced, so that the operation and maintenance cost in the later stage is reduced.
