Introduction of fire water tank
Fire water tank is provide water for the fire brigade in fire fighting and rescue activity of fire control facilities, according to the purposes are divided into circulating water tank and the circulating water tank. Have good water quality, clean and no pollution, high strength, light weight, etc. On the one hand, make the fire water pipe filled with water, save time full of pipes after fire pump open, won the time to put out the fire. Another aspect, roof pressurization, voltage regulation system and enrich the water tank can ensure fire hoses, to put out a fire early success has a decisive role.
Classification of fire water tank:
Fire water tank according to the different purposes of points: fire water tank is divided into circulating water tank and the circulating water tank. Circulating water tank at ordinary times maintain connection with the city tap water pipe network, the water in the tank in the circular flow state, when the earthquake struck, with the tap water pipe network automatically cut off, in order to make sure the tank is filled with clean water. It in addition to provide fire extinguishing the fire water, mainly used in the large-scale disasters as earthquake, when the city tap water pipe network paralysis for citizens to provide clean drinking water. Main set of circulation water tank in schools, parks, hospitals and other earthquake disasters occur for citizens to the place of refuge. The circulating water tank is not connect with tap water pipe network, the inside of the water undrinkable. Its role mainly in the fire hydrant cannot be used, fire-fighting water for the fire brigade.
Fire water tank material selection:
At present there are many kinds of suitable materials for the tank, the most common material with steel plate, stainless steel, reinforced concrete, glass, enamel materials such as steel, but they each have advantages and disadvantages.
Carbon steel tank plates welded together, the inner surface anti-corrosion treatment, and anti-corrosion material shall not be hazardous to health requirement.
At the scene of the reinforced concrete perfusion of the water tank, the weight is big, long construction period, and the piping side it is easy to leak, when cleaning the surface material is easy to fall off.
Enamel steel water tank is not affected by water quality pollution, to prevent steel corrosion, installation convenient and quick, not restricted by the civil progress, reasonable structure, sturdy and beautiful, deformation is not leaking, suitability is wide.
Glass fiber reinforced plastic water tank without being limited by the architectural space, strong adaptability, light weight, no corrosion, no leakage, good appearance, long service life, heat preservation performance is good, safe and reliable, convenient installation, cleaning maintenance is simple.
Stainless steel water tanks, polluting the water quality, corrosion resistance, no leakage, convenient cleaning, light weight, no breeding ground for algae, easy to heat preservation, beautiful, construction is convenient, but the price is high.
Fire water tank volume calculation:
Fire water tank is used to store early extinguish fire with water, fire fighting design specification clearly stipulated as follows:
"Code for fire protection design of buildings" article 8.6.3 regulation: indoor fire water tank water supply system (including partition partition tank) should be stored for 10 min fire consumption, not more than 25 l/s when indoor fire water, fire water stored more than 12 m3 tank via computation, still can use 12 m3; More than 25 l/s when indoor fire water supply, fire water tank via computation more than 18 m3, still can use 18 m3.
"Code for fire protection design of tall buildings" article 7.4.7.1 regulation: high fire water tank, fire water, a class of public buildings should not be less than 18 m3; 2 kinds of public buildings and a residential building should be not less than 12 m3; 2 kinds of residential building should be not less than 6.00 m3.
Article 7.4.7.3 regulation: parallel feed way of the partition of fire water tank capacity and high water tank is the same.
In addition, the fire water tank volume with other water share, in addition to meet their own fire water supply, also should satisfy other water supply.
Fire water tank other requirements:
Fire water a merger with other water tank, should have a fire water do not make his technical measures.
A fire, the fire pump fire water supply, should not enter the water tank should be set on the outlet pipe of fire water tank check valve.
Fire water tank should be in life and production water supply pipeline water filling.
In high-rise building fire water tank, appropriate USES two when a tank maintenance, still can save the necessary fire emergency water, and be at the bottom of the tank with contact tube connection, contact tube set on the valve, the valve is in a normally open state.
Share, the appropriate fire water tank and other water tank to tank of water flow in status updates, often with waterproof quality bad, other top drilling and other measures can be adopted siphon water supply.
Fire water tank accessories configuration and fire water tank installation, arrangement can be reference to the general water tank.
Fire water tank to note:
In the process of fire water tank cleaning, disinfection personnel must wear protective glasses, mask, such as tank feel discomfort, dizziness, eye pain, the heart is frowsty, gas tight, will leave pool, wash eyes, breathe the fresh air can be restored. Except clutter and qing pool, mud with shovel shovel out first in the pool and all kinds of sediment, then use broom or nylon brush from the top of the glass fiber reinforced plastic water tank - all round the walls - order of glass fiber reinforced plastic water tank bottom, repeatedly scrub in turn. Scrub is flush with water cannon whole again, discharge of sewage.
Fire water tank features:
1, USES the food grade resin, so the water quality is good, clean pollution-free;
2, have high strength, light weight;
3, corrosion resistance, good appearance, long service life, convenient maintenance management, etc.
Fire water tank price:
A. of glass fiber reinforced plastic water tank, fire water tank raw and auxiliary materials and accessories to choose a qualified supplier of fixed-point procurement.
B. whether or not to the supplier validated measures, shall be for incoming goods inspection.
C. of glass fiber reinforced plastic water tank of glass fiber products (including glass fiber surface mat, glass fiber needled mat, glass fiber yarn) tested surface density and linear density, moisture content and organic matter content testing, in line with the raw material, acceptance index before release.
D. of glass fiber reinforced plastic water tank for resin viscosity, solid content and gel time, meet the requirements, can be used.
E. except by testing the physical and chemical properties of raw and auxiliary materials, also deal with the appearance test, quantity, packing, inspection with the method of sampling the physical and chemical properties
