On the relationship between the fire water and outdoor fire water supply system in accordance with an outdoor fire water consumption, size, and degree of perfection of the outdoor fire water pipe network of protected areas, to meet the different requirements of different places, might read as follows: (1) When the fire-fighting Protected radius of not more than 150m, and the fire water and no more than 25L / s, due to the protection of the protected area are within a radius of fire water, and the volume of the smaller buildings, or factories, warehouses less combustible, outdoor fire water system requirements can be reduced accordingly, when the fire occurred, outdoor fire by the fire in the fire-fighting water directly out the fire. If the indoor fire system set fire pump adapter, the fire-fighting should be set in the range from pumps engagement of 15m ~ 40m. (2) When the protection is not greater than the radius of the fire pond 150m, outdoor fire water and more than 25L / s, if the municipal water supply is branched or only one inlet pipe for fire water absorbent can be used as a direct fire outdoor fire alternate water sources, which is equivalent to a second water main pipe in fire water pipe-line within 15m ~ 40m range must set the fire in order to connect the adapter to the outdoor pipe network by the fire when the fire. (3) When the protection is not greater than the radius of the fire pond 150m, municipal water pipe, inlet pipe can not meet the indoor and outdoor fire water, fire water and the sum is greater than 25L / s, taking into account such buildings are generally larger, flammable It was more larger fire water, usually less than the municipal water supply pipe network capacity required to be provided to improve the outdoor fire pipe network and fire pumps, in order to timely and effective delivery of fire water supply in case of fire. As shown in Figure 3. Figure 3 fire water sum> 25L / s (4) When the protection is greater than the radius of the fire pond 150m, because it has more than the radius of fire protection, so regardless of the size of fire water, are to be set up perfect outdoor fire tube Network and fire pressurized pump.
