Price:Stainless steel fire tank
Product introduction:Suzhou Shanghai stainless steel factory, stainless steel water tank fire water tank, fire water tank, stainless steel manufacturers, the price of the heat preservation water tank, water tank, washing tank, stainless steel cylindri
As we all know, all the fires have a fire in the early days of the fire proved to extinguish the fire at the initial stage, is crucial to avoid big fire, fire water tank for storing water to extinguish initial fire. Fire water tank water storage, on the one hand, the fire water supply pipe filled with water, save fire water pump after opening full pipe time, for extinguishing fire won time. On the other hand, the pressurization, pressure stabilizing system and water tank provided by the roof can guarantee the full water column of the fire water gun, and play a decisive role in the success or failure of extinguishing the initial fire.
Setting condition of stainless steel fire water tank
Stainless steel fire tank should be set in what circumstances, fire design specifications clearly defined as follows:
Article 8.6.3 2.1 "architectural design code for fire protection": set the constant high pressure water supply system of buildings, such as to ensure the most unfavorable point fire hydrant and sprinkler equipment such as water and water pressure can be set fire water tank. Set up temporary high-pressure water supply system building, should be set fire water tank or pressure tank, water tower.
2.2, "high-rise building design fire code" article 7.4.7 stipulates: the use of high-pressure water supply system, can not be located high fire water tank, when the use of temporary high-pressure water supply system, should be located high fire water tank. In addition, the centralized water supply system in the area can not guarantee the water quantity and water pressure of the fire hydrant and the automatic water spraying equipment in the indoor most disadvantageous places, but the fire fighting water tank can not be provided. But when the regional centralized temporary high pressure water supply system is used, the roof should be provided with fire fighting water tank for extinguishing the initial fire water.
Setting, location and height of stainless steel fire water tank
The setting, location and height of stainless steel fire water tank are specified as follows:
3.1, "building design fire code" article 8.6.3 stipulates: should be in the highest part of the building gravity gravity fire water tank.
3.2, "high-rise building design fire code" article 22.214.171.124 stipulates: "high fire water tank settings height should guarantee the most adverse point hydrant static pressure.". When the building height is not more than 100m, the most unfavorable point of high-rise building fire hydrant hydrostatic pressure should not be less than 0.07MPa, when the building height exceeds 100m, the most unfavorable point of high-rise building hydrant hydrostatic pressure should not be less than 0.15MPa. When the high level fire water tank can not meet the above static pressure requirements, booster facilities should be installed.
Volume calculation of fire fighting water tank for stainless steel
The stainless steel fire fighting water tank is used for storing and extinguishing the water used in the early stage of fire, and the design code for fire protection is clearly stipulated as follows:
Article 8.6.3 4.1 "architectural design code for fire protection": indoor fire water tank (including water tank water supply system partition partition) should be stored in 10min when the indoor fire water, fire water does not exceed 25L/s, the calculation of more than 12m3 water storage tank fire, still using 12m3; when the indoor fire water more than 25L/s, the calculation more than 18m3 water storage tank fire, still using 18m3.
Article 126.96.36.199 4.2 "fire protection design of tall buildings": fire water fire water tank, a class of public buildings should not be less than 18m3; two kinds of public buildings and a residential building should not be less than 12m3; two residential buildings should not be less than 6.00m3.
Article 188.8.131.52 provides: parallel water supply zone, fire water tank capacity and high fire water tank the same.
In addition, with other use of hydration fire water tank volume, in addition to meet their own fire water reserves, but also to meet other water storage.
Other requirements for stainless steel fire water tank settings
5.1 fire water and other water tanks merged, fire water should not be used for technical measures.
5.2 after the fire, fire water supply for fire water should not enter the fire tank, should be in the fire water tank on the outlet pipe
Check valve set.
5.3 fire water tank should use life, production of water pipes filled with water.
5.4, high-rise building fire water tank should use two, in a water tank overhaul, still can save the necessary fire emergency water,
And should be connected at the bottom of the tank with a connecting pipe, the contact pipe set up the valve, the valve is normally open.
5.5 fire water tank should be combined with other water tanks, so that the water inside the tank is often in a state of flow renewal, to waterproof, qualitative change bad,
Other water can be supplied by siphon, top drilling and other measures.
The configuration and fire water tank accessories 5.6 fire water tank installation, can refer to the general layout of water tank, this is no longer that levin.
