Abstract
The utility model discloses special water supply equipment for the fire protection of a pressure reinforcement and stabilization system of a roof of a high-rise building. The utility model comprises a high cistern for roof fire protection, pressure reinforcement pump, an air pressure water tank, a fluid flow controller, an electric control cabinet, an air admittance check valve, an air reinforcement tank, an air reinforcement check valve, an electro connecting pressure gauge, a water level controller, etc.; besides, the utility model is additionally provided with two electromagnetic valves; in order to prevent water waste, a water discharge pump is also arranged on the utility model. The utility model has the advantages of simple and reasonable structure, convenient fabrication and installation, supermatic air and pressure reinforcement, safety and reliability, and is the self rescue and requisite packaged product for the roof fire protection of the high-rise building in the initial stage of fire hazard.
Description
The utility model relates to a kind of water supply facilities, relates in particular to a kind of highrise building roofing supplementary pressure, pressure-stabilized water-supplying equipment.
The problem that existing high building fire fighting often is ubiquitous is: when the roofing fire water box, and insufficient height, and cause fire initial stage roof number layer fire fighting hydraulic pressure deficiency.
The purpose of this utility model is: the special-purpose water supply facilities of the fire-fighting that provides a kind of draining that is applicable to that auto-pneumatic cylinder, air supply tank are lower than the situation of roofing fire water box, tonifying Qi process can not flow into high level cistern again certainly.
The utility model comprises roofing fire-fighting high level cistern, augments press pump, auto-pneumatic cylinder, liquid flowing controller, electrical control cubicles, breather check valve, air supply tank, tonifying Qi flap valve, electro connecting pressure gauge, water level controller etc., and has set up two electromagnetic valves; Be the water that avoids waste, be provided with drainage pump, at this moment, also saved the capital cost that roofing is built supplementary pressure system water pump house.
The utility model is simple and reasonable, make easy for installation, tonifying Qi, supplementary pressure are increasingly automated, safe and reliable, meeting the requirement of " Code for fire protection design of high rise buildings GB50045-95 " (version in 1997), is the indispensable complete sets of products of fire of high-rise building initial stage roofing fire-fighting self-rescue; The utility model can replace the function of stabilized pressure pump in the fire-fighting main pump, can not establish stabilized pressure pump, has saved investment, has improved the security reliability of fire-fighting.And its air mends the air compensation into auto-pneumatic cylinder, can be controlled by the time relay, also can for reducing cost, can not adopt time relay control scheme by the low water level electrode control of water level controller.
Accompanying drawing: be structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model comprises roofing fire-fighting high level cistern 1, augments press pump 2, auto-pneumatic cylinder 6, liquid flowing controller 7, electrical control cubicles 8, breather check valve 9, air supply tank 10, tonifying Qi flap valve 11, electro connecting pressure gauge 12, safety valve 13 and water level controller 14 etc.Auto-pneumatic cylinder 6, air supply tank 10 are lower than roofing fire-fighting high level cistern, have additional electromagnetic valve 5 at auto-pneumatic cylinder 6 and 10 of air supply tanks, and have additional electromagnetic valve 4, drainage pump 3 successively at air supply tank 10 and 1 of roofing fire-fighting high level cistern.Air supply tank 10 is from the water inlet of auto-pneumatic cylinder 6 bottoms, supplementary pressure, and water is from the bottom water outlet in the air pressure tank 6.
Its principle and running are as follows:
After auto-pneumatic cylinder lost gas, the interior water level of auto-pneumatic cylinder surpassed the highest design water level when stopping to augment press pump 2, is provided with the level electrode of water level controller 14 at the peak level place, and control electromagnetic valve 4 is opened with pump 3 and opened, and electromagnetic valve 5 cuts out.The air supply tank draining is air-breathing, and after the water emptying was filled air, electromagnetic valve 4 closes and pump 3 stops, and electromagnetic valve 5 leaves, and by water-head in water level in the air pressure tank 6 and the air supply tank 10, the air in the air supply tank 10 is mended in the air pressure tank 6 through one way valve 11.
The time length that (water pump 3 also leaves) electromagnetic valve 5 closes opened by electromagnetic valve 4 so that the air in the air supply tank is mended fully into auto-pneumatic cylinder is as the criterion, by time relay control electromagnetic valve and drainage pump, or control by the water level controller low water level electrode, air compensation is then irrelevant with the time relay, only with high and low level electrode between volume relevant.
Tonifying Qi is through behind the certain hour, if water level is lower than the peak level electrode in the auto-pneumatic cylinder, the state that then still keeps electromagnetic valve 4 passes [drainage pump 3 also stops], electromagnetic valve 5 to open, the peak level electrode still in water or another time open and augment press pump 2, water level rises, the peak level electrode is not had by water logging, then repeats the tonifying Qi action again.Until reaching peak level is again fire house when needing maximum working pressure (the maximum working pressure electrode that is set by supplementary pressure pump performance and electro connecting pressure gauge is determined), augments press pump, drainage pump quits work, and leave electromagnetic valve 4 passes, 5.Auto-pneumatic cylinder 6 is in the guard state that guarantees water retention capacity and pressurize.
Work as breaking out of fire, during fluid level controller 7 actions, must design on the drainage system circuit of (containing drainage pump 3 and drain solenoid valve 4) has normally closed (moving the opening) of liquid flowing controller contact; And often the opening of fluid level controller (moving closing) contact arranged on the circuit of augmenting press pump 2 of supplementary pressure system.So just can reach designing requirement.By standard, supplementary pressure system input was put out a fire after 30 seconds, and main fire pump drops into fire extinguishing (or other measure is put out a fire main fire pump input) in succession.At this moment, the supplementary pressure system can excise.Fire-fighting finishes, and manual-lock master fire pump, augments press pump, to quit work.
