Description of drawings
Fig. 1 is the structural representation of gas roof pressure fire water supply equipment of the present utility model: 1 valve; 2 air gauges; 3 water pressure gauges; 4 check-valves; 5 water level meters; 6 diaphragm type pressurized tanks; 7 pressure-reducing valves; 8 water pumps; 9 gas roof pressure compensating tanks.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Fig. 1 is the structural representation of gas roof pressure fire water supply equipment of the present utility model, and gas roof pressure compensating tank is connected with the building fire_fighting pipe network; Gas roof pressure compensating tank is connected on the water tank by diaphragm type pressurized tank 6 and water pump group 8; Gas roof pressure compensating tank is provided with water level meter 5 and air-stopping valve 1; And also be connected with low pressure air compressor on the gas roof pressure compensating tank.
Gas roof pressure compensating tank is connected with gas cylinder by pressure-reducing valve 7 and Pressure gauge, is connected with High Pressure Air Compressor on the gas cylinder.High Pressure Air Compressor, low pressure air compressor, Pressure gauge 2 are connected on the switch board by circuit; The operation of switch board control whole system, switch board is equipped with uninterrupted power source, guarantees the operation of entire equipment.。
Gas pressure stabilizing device operation principle: at first start the water filling in gas roof pressure compensating tank and system of water pump 8 equipment before the operation of gas roof pressure device start, after reaching certain water level, water pump quits work, water pump preferably adopts the using and the reserved working method, when at this moment the pressure pressure that is in default rolls off the production line, air compressor machine tonifying Qi in trend gas roof pressure compensating tank, when reaching certain setting pressure, air compressor machine quits work, this is finishing of a voltage stabilizing cycle, when gas roof pressure compensating tank water level drops to certain water level, water pump 8 starts moisturizing in system automatically, when water level rises to certain water level in the gas roof pressure compensating tank, water pump 8 quits work, in order to guarantee to prevent that in the moisturizing process gas roof pressure compensating tank internal pressure is too high, when being higher than certain voltage-stabilizing system pressure, the magnetic valve 1 at gas roof pressure compensating tank top is opened pressure release automatically, balance with gas pressure in water level liquid level position in the assurance gas roof pressure compensating tank and the gas roof pressure compensating tank jar, when if the interior gas pressure of gas roof pressure compensating tank this moment does not reach setting pressure, air compressor system starts tonifying Qi in gas roof pressure compensating tank automatically, when the force value of default, air compressor machine quits work automatically, so circular flow is worked to guarantee that voltage-stabilizing system is in water level in the gas roof pressure compensating tank of setting and the pressure limit, reaches the purpose of voltage stabilizing.
Gas cylinder system: gas cylinder system is equipped with the gas cylinder group, each gas cylinder group is passed through pipeline, valve is connected with gas roof pressure compensating tank air inlet, the gas cylinder internal pressure is set between the 12MPA-15MPA, outlet pressure is set in certain pressure and rolls off the production line, gas cylinder system is kept pressure always in the time of usual, devote oneself to work when having the fire-fighting fire to take place, during whole fire-fighting system breaking out of fire, gas voltage stabilizing compensating tank internal pressure sharply descends, when dropping to certain pressure, the gases at high pressure of gas cylinder group and the gases at high pressure of air pump add to rapidly in the gas roof pressure compensating tank, fire-fighting emergent water in the gas roof pressure compensating tank is ejected in the fire-fighting fire extinguishing pipeline, to guarantee ten minutes water recharging of fire-fighting emergent fire extinguishing.
Air compressor system: native system can be set one or two air compressor machine work, the working method of an air compressor machine is, keep-up pressure at ordinary times pipeline or gas cylinder group, collaborative gas cylinder system was got to the fire-fighting emergent water in the gas roof pressure compensating tank in the fire protection pipeline system with the fastest speed when fire was arranged.The working method of two air compressor machines is: big air compressor machine is in the cotton for wadding state at ordinary times, only when fire takes place or small air compressor just start when breaking down, small air compressor plays voltage stabilizing pressurize effect at ordinary times, therefore in the large-scale preferred working method that adopts two air compressor machines in fire-fighting system the inside, small-sized fire extinguishing system preferably adopts the working method of an air compressor machine.
The big small air compressor course of work: open the outlet of pumping system pipeline and be connected with the top air inlet pipe of gas roof pressure compensating tank, a check valve 4 is adorned in every air compressor machine outlet, the water that guarantees voltage stabilizing gas and pipeline the inside can not be back in air compressor machine or the gas cylinder group, small air compressor starts to voltage-stabilizing system and pipe-line system when voltage-stabilizing system pressure drops to certain pressure, gas cylinder system is suppressed, reach on the pressure set points in limited time up to gas roof pressure compensating tank internal pressure, air compressor machine quits work, when the small air compressor fault or pressure sharply drop to pressure and set when rolling off the production line, big air compressor machine work reaches voltage-stabilizing system pressure and sets needs.Through above-mentioned circular flow process, guarantee that voltage-stabilizing system and gas cylinder system are stabilized in the pressure limit of setting, reach the pressure stability needs of an air compressor machine or multiple air compressors fire-fighting voltage-stabilizing system.
Fire-fighting start-up course: when the fire-fighting fire incident, fire hydrant, spray system outlet valve and shower nozzle are opened, when at this moment voltage-stabilizing system pressure quickly falls to setting pressure, magnetic valve 9 is opened rapidly, gas cylinder system, the tonifying Qi in gas roof pressure compensating tank compensating tank simultaneously of big or small air compressor system, gas roof pressure compensating tank jar internal gas pressure raises, in the process that this moment, the pressure in gas roof pressure compensating tank raise fire-fighting emergent water in the gas roof pressure compensating tank is reached in the fire protection pipeline, guarantee that 10 minutes fire-fighting emergent water needs.
In order to prevent that gas from entering in the fire demand water pipeline, guarantee the water safety of fire protection pipeline, increase by a cover vacuum at gas roof pressure compensating tank delivery port and suppress negative pressure shutoff device 5, to guarantee that gas can not enter in the fire protection pipeline system in the gas roof pressure compensating tank, to guarantee fire protection pipeline fire-fighting fire extinguishing water safety.
When electrical system during malfunctioning or fault, in order to insure, simultaneously also in order to prevent that water enters in gas cylinder or the air compressor machine in the gas roof pressure compensating tank, gas stabilized pressure pump group water inlet installs a water level fluid level control valve additional in gas roof pressure compensating tank, as above-mentioned fault appears, gas pressure stabilizing device delivery port is closed, water level rests on gas roof pressure compensating tank top once on the designated water level position, water level no longer raises, to guarantee that fire demand water can not enter in gas voltage stabilizing pipeline and air compressor machine, the gas cylinder, guarantee air pressure voltage-stabilizing system safety.
