Fire gas top pressure water supply equipment
Product overview
Building fire water supply system is usually used to replace the high pressure tank water tank, 10 minutes early to meet the fire with water, but often use an ordinary pressure tank to occupy a larger space, our company produces DLC series gas top pressure fire water supply equipment is based on the GB27898-2011 standard for the new fixed fire extinguishing device production basis. Pressure tank volume of the device is normal pressure tank 1/3~1/5, save the area, water supply pressure is stable, large emergency fire pressure water supply equipment ideal.
Working principle
Fire gas top pressure water supply equipment in the fire pressure tank is the water storing component, the available water capacity of not less than 3m fand. The pressure tank adopts air pressure tank type. This kind of equipment by the large pressure tank to provide early 10min fire water, no fire pumps, fire pump group has only. The main difference is that the gas top pressure device using high pressure gas storage cylinder group dynamic fire control work when the power source and the pressure tank, when the fire command to start, top pressure system to meet the input pressure tank of compressed gas pressure in the tank fire, fire and water replacement discharge, fire water supply with constant pressure fire part.
Daily pump work will be sent to the network and water pressure tank, pressure tank when the liquid level reaches the set value limit, water pump stops working. The air supply system working pressure is low, when the pressure regulator to the upper limit, stop the air. The system usually causes Water Leakage pipeline pressure drop, pump start water level controller by the control system; the lack of gas by pressure controller of air supply system (air compressor) start stop air pressure tank; it can do the daily vapor-liquid equilibrium, the pressure and liquid level interlock. When a fire occurs, the fire signal input, gas top pressure system power source release, uniform filling pressure tank in the water into the top of the fire pipe network, provide not less than 10min to the fire water pipe network.
Equipment composition
Equipment by the touch screen type intelligent control system, pump group, pneumatic water tank, high pressure cylinders, gas top pressure regulator system, pump, automatic gas stop device, a liquid level control device, control instrumentation, piping and valves etc..
Product features
DLC series of gas top pressure fire water supply equipment, using programmable man-machine interface control technology, with an independent gas source and intuitive liquid level display device, effectively ensure the safe and stable operation of the equipment. Its main features are as follows:
1, the product has advanced multi-function programming control, the picture shows the running state, can receive a variety of fire signals and can be connected with the fire center.
2, the product has two power interface, with automatic switching function.
3, the device is equipped with a dry battery backup power supply, the fire can still work under the condition of power failure.
4, compact structure, small footprint, easy to use.
5, safe and reliable, complete protection function, ensure that no danger of anything going wrong operation.
6, the product can be stored for 10 minutes of fire water, can replace the indoor fire water tank, with investment, short construction period, construction and installation is simple, easy to realize the advantages of automatic control.
Volume 7, design the same effective fire water required pressure tank than normal pressure water supply equipment to. The top of gas and water gas pressure equipment, pressure tank volume ratio of 10% to 90%, the proportion of common type is about (65%-75%): (35%-25%); as shown in Figure 4 the total volume of air pressure tank 20m fand, using gas top pressure equipment can provide effective 18m fand fire water, and ordinary pressure equipment up to provide effective fire water fand 12m;
8, effective fire top pressure equipment to provide water supply with constant pressure mode, solves the common fire pressure water supply equipment in the constant pressure tank volume (for the equipment area no longer increase) cases, in order to increase the effective supply of water to meet the fire problem, inconvenience and cost increase waste water pressure difference brings to the pipeline pressure design;
9, based on the characteristics of the 1 important components, small pressure storage tank area equipment, can be placed on the ground floor or basement, especially suitable for low rise buildings, light material building, workshop, warehouse and set the high water tank construction inconvenience;
10, the power source system of top pressure equipment is relatively independent of the water supply network, just start working at the required fire, so to achieve daily regulated working pressure is lower than the pressure in the fire work, compared with the ordinary pressure water supply device can greatly reduce the operation cost.
11, the whole system has the advantages of low cost, due to the same water condition, the total volume of air pressure tank equipment is greatly reduced, small occupied area, fire facilities connected with the pressure level is well controlled, and even can be reduced, by using this type of equipment can make the automatic sprinkler system benefit in the aspects of design, installation and use etc..
Gas top pressure fire water supply equipment has the above characteristics, so that the type of equipment in recent years has been more and more accepted by the design department, the majority of users, and its promotion in line with the requirements of the establishment of a conservation oriented society.
Product use
Gas top pressure fire water supply equipment used for fire emergency fire 10 minutes, suitable for hotels, hotels, entertainment, residential, warehouse, airport, especially suitable for buildings in earthquake areas, concealed works and temporary buildings and architectural arts requirements should not be set high water tank construction.
Gas pressure type fire fighting water supply equipment is advanced, reliable, practical and economical fire water supply equipment
