Hydrant hydrant water pressure should not be greater than 0.80MPa, when greater than 0.80MPa, you should take sub district water supply system. When hydrant outlet pressure is greater than 0.50MPa, hydrant system should be equipped with pressure reducing device.
The hydrant hydrant should be 1.10M from the ground, and the direction of the water outlet should be downward or perpendicular to the wall of the hydrant.
The fire hydrant spacing should be calculated, and the high-rise building should be no more than 30m, the podium should not be greater than 50m.
Hydrant water column full water column should be determined by hydraulic calculation, and the building height is not more than 100mm of high-rise buildings should not be less than 10m; building height of more than 100m high-rise buildings should not be less than 13m.
Fire hydrant should be located in the aisle, near the stairs and other obvious easy to use the place, fire hydrant spacing should ensure that the same floor, there are two parts of fire hydrant water column, full water column at the same time.
