Description
The utility model relates to water supply installation, particularly life-fire-fighting watering device.
What water for fire generally adopted at present is the measure of drawing water from the living water use pipeline or from storage cistern and pressurizeing, in modern high-rise building, adopt pressure water supply, the water supply installation that is used for living water use can't guarantee fire fighting supply amount and pressure, yet the water application efficiency that fire-fighting is used is low, therefore, fire-fighting and living water use can not use simultaneously.
Chinese patent has proposed to guarantee life and the common water supply installation of fire-fighting in " the shared pressure watering device of life-fire-fighting " literary composition of bulletin on September 26 nineteen ninety, be mainly the air pressure closed tank and connect life pipe-line system and firemain system, two level relays are housed respectively on the air pressure closed tank and are connected with the storage cistern pipeline, living pump and air supply tank are equipped with in the centre, storage cistern is connected with firemain system simultaneously, and fire pump is equipped with in the centre.Yet, use or water level drops to below the life pipeline air shuttle valve first, after air shuttle valve is closed, there is pressure differential with the life pipeline that communicates with atmosphere in the basin, air shuttle valve is difficult for opening when use for the first time maybe will recover ordinary water level.When living water use, fire pump, air compressor are all inoperative.Shelve for a long time, the equipment rust corrosion that makes moist, however equipment is out of control easily when promptly needing with fire fighting supply.
It is a kind of simple in structure that the purpose of this utility model is to provide, and can guarantee living water use; Can guarantee simultaneously the shared pressure watering device of life-fire-fighting of water for fire again.
For reaching above-mentioned purpose, the utility model has adopted the shared pressure watering device of a kind of life-fire-fighting, it is installed on the supply channel, the shared pressure watering device of life-fire-fighting, living water use pipeline and water for fire pipeline are installed below the pressurized seal basin, and between living water use pipeline and water for fire pipeline, bypass pipe is set, simultaneously on the pipeline between life pipeline and the pressurized seal basin, pressure regulator valve is set, its end is equipped with uses penstock, joint, bottom in the front end of living water use pipeline and the pressurized seal basin is provided with ball float and ends valve, be equipped with on the side in the pressurized seal basin, following content gauge, be connected by pipeline and air compressor on the another side of its pressurized seal basin, electro connecting pressure gauge and safety valve are equipped with in the top of pressurized seal basin.
The utility model has the advantages that:
(1) simple in structure, easy to maintenance, cost is low;
(2) realize Automatic Control, and guaranteed life and shared output of fire-fighting and hydraulic pressure.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the shared pressure watering device schematic diagram of the utility model life-fire-fighting.
As shown in Figure 1, the shared pressure watering device of the utility model life-fire-fighting, it is installed on the supply channel, the shared pressure watering device of this life-fire-fighting is installed living water use pipeline 2 and water for fire pipeline 1 below pressurized seal basin 15, and between living water use pipeline 2 and water for fire pipeline 1, bypass pipe 21 is set, simultaneously on the pipeline between life pipeline and the pressurized seal jar 15, pressure regulator valve 7 is set, its end is equipped with penstock 18 and middle the placement installs valve 8, joint, bottom in the front end of living water use pipeline 2 and the pressurized seal basin 15 is provided with ball float and ends valve 6, on a side of 15 of pressurized seal basin, be equipped with, following content gauge 3,4, be connected by pipeline and air compressor 16 on the another side of its pressurized seal basin 15, electro connecting pressure gauge 13 and safety valve 14 are equipped with in the top of pressurized seal basin 15.
In the middle of the said living water use pipeline pressure regulator valve 7 is housed, its hydraulic pressure is decided by living water use.
The corresponding site of said pipeline is equipped with general gate valve 19 and flap valve 20, the power supply of this device is controlled by electrical control cubicles 17, the water level of living water use is by content gauge 3,4 controls, the water level of water for fire is guaranteed by air shuttle valve 5, air compressor 16 is controlled by contact pressure table 13, in order to guaranteeing the air pressure in the pressurized seal basin, water pump 11,12 is by content gauge 3,4 and electrical control cubicles 17 controls, thereby realized that the shared water of life-fire-fighting controls automatically.
The course of work of the shared pressure watering device of the utility model life-fire-fighting:
Open the gate valve 10 on the bypass pipe 21, electrical control cubicles 17 enters auto state, water pump 11,12 water filling in trend pressurized seal basin 15 that links to each other with reservoir, pump trip when water level rises to content gauge 3, air compressor 16 startups simultaneously are inflated to electro connecting pressure gauge 13 upper limits.This moment, pressurized seal basin 15 interior air water balances were closed life pipeline gate valve 9 then, made ball float end valve 6 and relied on automatic buoyancy to open under pressure balance, and closing gate valve 10 again; Open life pipeline gate valve 9, preparation finishes, and enters normal operating conditions.
The living water process is as follows:
Open the arbitrary water tap 18 on the life pipeline 2, water storage is supplied water to the life pipeline 2 that is connected to pressure regulator valve 7 under compressed-air actuated effect in the pressurized seal basin 15, when the drawdown in the pressurized seal jar 15 during to content gauge 4, water pump 11 starts to supply water in the pressurized seal jars 15 to content gauge 4 and stops.When drawdown was to content gauge 4 for the second time, water pump 12 started, circulation successively, and water pump 11,12 alternations have guaranteed the living water use supply.When using living water use to enter the peak; water pump 11 or 12 independent unlatchings still can be satisfied; be that pressurized seal basin 15 interior water levels do not reach content gauge 3; time relay control in the electrical control cubicles 17; double pump starts water filling simultaneously; stop until content gauge 3; move in circles and reach the purpose of uninterrupted water supply; when having a power failure or cut off the power supply; be the gentle pressure of the fire-fighting water yield that guarantees that pressurized seal basin 15 is specified; when water level was reduced to air shuttle valve 5, air shuttle valve 5 was closed automatically, sent after the electricity; starting mode of pump; open gate valve 10 so that air shuttle valve 5 starts, to content gauge just often; closing gate valve 10; promptly enter normal operating conditions again, at this moment, gas loss in the pressurized seal basin 15; the water pump moisturizing is to content gauge; electro connecting pressure gauge 13 is down in limited time, and air compressor 16 starts, in gas replenishment process; liquid level drops to content gauge 4; water pump 11; 12 start water filling, close air compressor 16 simultaneously, treat that water is to content gauge 3 upper limits; air pressure still is lower than electro connecting pressure gauge 13 lower limits; air compressor 16 starts tonifying Qi to the upper limit shuts down, and has so far finished the tonifying Qi work of waterworks, has guaranteed the air water balance in the pressurized seal basin.
The fire fighting supply process is as follows:
Under power failure or powering-off state, start the hydrant in the fire main 1, the fire-fighting water yield of storing in the pressurized seal basin 1 enters pipeline under gas pressure, can put out a fire.Provide water for fire to reduce to air shuttle valve 6 to pressurized seal basin 15 interior water levels after ten minutes, air shuttle valve 6 is closed automatically, prevents that gases flow into fire mains in the pressurized seal basin 15.Fire extinguishing finishes, and power supply is normal identical with living water.If power supply is normal, then water pump 11,12 alternately or jointly supplies water for fire main.
