Fire monitor system acceptance of the three standards
1, system settings 1.1 General provisions 1.1.1 water supply pipe should be the production of water pipes separately.
1.1.2 water supply pipe and the bubble should not be combined with the mixture supply pipe. Cold water supply pipes wet areas frost protection measures should be taken, excluding dry pipes should be located within the water pipes and air facilities. Pipeline should be designed to meet the design flow, pressure and open to the injection time requirements.
1.1.3 Fire water should not be less than the specified capacity of extinguishing time and cooling time, need to use water cannons, bubble guns, water curtain protection Sprinklers Water and water supply pipes and other water-filled sum. The capacity may be reduced by extinguishing time and cooling requirements of time to add water.
1.1.4 Fire Pump The water pressure system should be able to meet the water cannons, foam gun injection pressure requirements.
1.1.5 Extinguishing agent And the pressurized gas supply time should be less than 48h.
1.1.6 water cannon artillery system and the foam to the foam injection system from the start time of water or foam should not exceed 5min, dry powder gun system from dry start to the muzzle blast of the time not more than 2min.
1.2 Fire gun Layout 1.2.1 layout of indoor fire monitor the number of not less than two, the layout should ensure a high degree of artillery fire from the jet, the influence of the upper building structure and should allow two water cannons while the water jet protected areas to reach any part of.
Indoor system should be used wet water supply systems, fire emplacements Department should set the fire pump start button.
Set fire gun platform, its structural strength to be able to meet the requirements of fire monitor jet reaction force, the structure should be designed to meet the normal use of artillery fire requirements.
1.2.2 layout of outdoor fire monitor fire monitor jet should enable complete coverage of protected areas and protected objects, and should meet the fire requirements of strength and cooling intensity.
1. Fire monitor the protected areas should be set in the perennial dominant wind direction of the wind;
2. When the fire object height higher, larger, or fire bombs in the major obstacles to higher jet block should be set to fire the turret.
1.3. Water gun system 1.3.1 Design of the water gun range and flow shall meet the following requirements:
1. Water gun design a range of compliance requirements decorated artillery fire. Interior decorated water cannons and a range of indicators should be a range of value products, outdoor water cannons decorate the range of product range should be 90% of index value.
2. When the water cannons and product design working pressure not rated working pressure, it should also work under pressure in the product range of choice.
3. When calculating the design of water cannon artillery range of layout does not meet fire safety requirements should be adjusted number of original design of the water cannons, layout position or size models.
1.3.2 Layout of the water cannons outside the rated flow of not less than 30L / s.
1.3.3 fire fighting and cooling water cannon system, continuous water supply time should meet the following requirements:
1. Fighting indoor Fire Fire-fighting water to attack a time not less than 1.0h.
