Abstract
The utility model discloses a water supply device for fire control for tall buildings, which is provided with an air pressure water storage tank. An air pressure water level balancing device is connected between the air pressure water storage tank and a living water tank, and the air pressure water storage tank is also communicated with the water supply pipe of a water pump via an air-water compensating pipe. In the short time when the water inlet ball float valve of the living water tank is closed and the water pump is delayed to be closed, air and water in the air-water compensating pipe enter the air pressure water storage tank to realize the air-water compensation. When air pressure or water level in the water storage tank exceeds the predetermined value, the superfluous air or water is drained into the water tank via the air pressure water level balancing device, so that the pressure and the water quantity in the air pressure water storage tank are kept to be stable.
Description
The utility model relates to a kind of fire-fighting watering device, for the usefulness of high building fire fighting.
For highrise building, the fire fighting supply facility is absolutely necessary.General way is that two combine into one with water for fire and living water use, uses a water tank.But because of the pressure height of the pressure ratio living water use of water for fire, so water tank must be raised to increase pressure.Do the attractive in appearance of not only influence building like this, but also increased the operating cost of construction cost and water system.Sometimes for the attractive in appearance of highrise building in addition increase build one deck building so that and the high level cistern harmony, this is just more uneconomical.In order to address this problem, have the people once to propose the air pressure tank water supply installation, it has an air pressure water tank, in adorn required water for fire, and fill air with certain pressure.In order to keep jar interior pressure also need be equipped with a cover air compression plant and a control system, so that give tonifying Qi in the air pressure tank regularly.Thereby the complex structure of this fire-fighting watering device, expense height need be established the special messenger and operate, safeguard.For above-mentioned reasons, this fire-fighting watering device is in fact seldom adopted by the people.
The purpose of this utility model is to overcome above-mentioned weak point in the prior art, provides a kind of simple in structure and can keep the fire-fighting watering device of the certain pressure and the water yield automatically.
Task of the present utility model realizes by following approach.Fire-fighting watering device decides device by air pressure water tank, air pressure water level weighing apparatus and the air water compensating pipe is formed.Dress water for fire and fill air in the air pressure water tank with certain pressure.The end that air pressure water level weighing apparatus is decided device communicates with the air pressure water tank, and the opening of this end is positioned at giving of air pressure water tank and decides the water level place; The other end that air pressure water level weighing apparatus is decided device communicates with water supply tank.One end of air water compensating pipe communicates with air pressure tank, and the other end communicates with water service pipe from water pump.On the air water compensating pipe, be provided with an one way valve.
It is that a water supply tank is filled water on one side and static pressure that another side had that above-mentioned air pressure water level weighing apparatus is decided device, equals the communicating pipe that the air pressure water tank gives level pressure power.
The operating principle of this device is such: when the water of water supply tank arrives predetermined water level, the water inlet float valve of water supply tank is closed automatically by waterpower, water pump delay a period of time closes, at this moment, water and ducted air enter the air pressure water tank by the air water compensating pipe, and the pressure that compensation produces because of leakage falls.Air pressure in the air pressure water tank surpasses rated pressure or water storage and surpasses and give when deciding water level, and unnecessary air or water are decided device by air pressure water level weighing apparatus and is discharged in the water supply tank.Because whenever cutting out, water pump replenishes a G﹠W once just for the air pressure water tank, so the air pressure water tank can keep giving the fixed air pressure and the water yield all the time at ordinary times.
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is a kind of structure chart that air pressure water level weighing apparatus is decided device.
Below in conjunction with accompanying drawing content of the present utility model is specifically described.
As shown in Figure 1, the air pressure water tank be an airtight container, interior dress water for fire, and filling giving the air of level pressure power, its bottom is connected to outlet pipe 13.It is U-shaped pipes that pressure water level weighing apparatus is decided device 6, and the one end communicates with the bottom of water supply tank 9, and the other end communicates with air pressure water tank 5, and its end is a decurved slightly elbow, and the opening 8 of this elbow is positioned at giving of water tank 5 and decides water level face place.The height h of the pipeline between the bottom of the bottom of U-shaped pipe 6 and water supply tank 9 determines by following formula:
H=(P)/(r) (centimetre)
In the formula: P is that the air in the air pressure storage tank gives level pressure power (KGf/cm
2), r is the proportion (KGf/Cm of water
3).Be that the air that the static pressure of water in the pipeline 7 equals in the air pressure water tank gives level pressure power.One end of air water compensating pipe 3 feeds from the top of air pressure water tank 5, and the other end communicates with water service pipe 2 by tee piece 10, and tee piece 10 also communicates with water supply tank 9.On air water compensating pipe 3, be provided with an one way valve 4.When water tank water intake float valve 11 is opened, during water tank 9 water inlets, one way valve 4 is not opened.When in the water supply tank 5 and water level arrive when giving alignment, water inlet float valve 11 is closed, this moment, the controller by water pump 1 made water pump 1 postpone a period of time to cut out (as several seconds or determined by design for tens seconds), because water intaking valve 11 is closed, the water pump operation operating point moves to left, and the pressure in the air water compensating pipe 3 increases, and one way valve 4 is opened, water and ducted air enter air pressure water tank 5, thereby realize the air water compensation.After water pump 1 cut out, water supply tank 9 water levels reduced, and the water inlet float valve is opened, and the water in the air water compensating pipe flow to water supply tank (9), and mends air in the air water compensating pipe.Air pressure in air pressure water tank 5 surpasses the level pressure power of giving, that is when surpassing the static pressure of water in the pipeline 7, unnecessary air enters water tank 9 by U-shaped pipe 6 and emits, when air pressure drops to predetermined value till.When the water storage water level surpassed elbow opening 8, unnecessary water was discharged in the water tank 9 by U-shaped pipe 6, drops to up to water level on the position of opening 8.Therefore, remaining in the air pressure water tank and giving fixed pressure and moisture storage capacity.
In order to increase each air water compensation rate, an air water supply jar 12 can be set at the front end of air water compensating pipe 3.
Air pressure water level weighing apparatus is decided device can also adopt as shown in Figure 2 structure, and it is made up of interior pipe 14 and outer tube 15.One end and the water supply tank 9 of interior pipe 14 join, and the other end inserts the bottom of outer tube 15, and the upper end of outer tube 15 joins by pipeline and air pressure water tank.
The utility model compared with prior art, that its advantage is is simple in structure, cost is low, owing to utilized domestic water supplying system to realize air water compensation and balance, so pneumatic water storage tank can often keep giving fixed pressure and moisture storage capacity automatically. In addition, in the operating pressure water storing tank water circuit also so that the water storage in the pneumatic water storage tank undergo no deterioration.
