Overpressure of fire hydrant and its solution measures;

Analysis of mathematic model in indoors fire hydrant systems;

Approaching to the way or water supply of indoor fire hydrant for high-rise building;

Combined with fire protection code in architecture design and actual situation of Yangquan city the matters needing attention in fire fighting design in multistory buildings are discussed according to the distribution of fire cock, pump adapter in high pressure system and other aspects.

According to fire control standard,it introduces water supply for fire control of commercial building from selection of fire pump、fire cock、collocation of spraying systematical water pump and selection of fire rolling screen,which to perfect design of fire control.

Probing into Supply Water Way of Hydrant in High Building;

The author introduces the theoretical definition of the underground garage and the content in the water supply and drainage design,discusses how to reasonably carry out the water supply and drainage design and the fire protection design in the underground garage design,puts forward the concrete drainage method,describes the arrangement of the hydrant and the nozzle in the fire protection design.

A new idea is proposed for calculation of the protective radius of hydrants, and through comparison of the practical example with the conventional way of calculation, the difference between the two ways is analyzed, which can be a reference for determination of the interval of hydrant layout in engineering design.
