Abstract
The utility model discloses a fire fighting water supply equipment with the pressure fixed by the nitrogen gas, which is provided for a voltage-stabilizing type water supply system. The utility model comprises a fire fighting pot and a nitrogen gas busbar, wherein, the nitrogen gas is on the upper part of the inside of the fire fighting; the water is on the lower part of the inside of the fire fighting pot; the outside of a pot body is provided with a water level gauge and a pressure gauge; the water input interface and the water output interface of the lower part of the pot are communicated with a life water supply network and a hydrant; the busbar comprises a nitrogen gas cylinder, a pressure-reducing valve, etc and a busbar pipeline is communicated with the pipe head of the gas input valve of the upper part of the fire fighting pot. Compared with the fire protection measures of an elevated water tank or the duplicate supply equipment, etc., the equipment is safe in operation but also is less in investment and convenient in management and operation.
Description
The utility model relates to a kind of standby waterworks, particularly a kind of pressurization by nitrogen gas water-supplying device for fire extinguishment.
At present aspect domestic water, replace elevated tank or water tower is more and more general from the beginning with stable-pressure device.This pressure-stabilized water-supplying device mainly is the feed pump by automatic control, with the domestic water that is located in ground or the underground storage tank (pond), be input in the vacuum tank, when the jar internal pressure reaches the bound that mixes up in advance, the electric contact pressure meter that is located on the jar will turn round to feed pump or stall control by electric cabinet, to keep the pressure stability of whole water system.But in case have a power failure, not only control system quits work, and feed pump can not replenish water supply, and the water that stores in the vacuum tank is used up at short notice.If the generation condition of a fire, this water system will be brought great harm to fire-fighting work.
The purpose of this utility model provides a kind of under the condition that the type voltage regulation water system has a power failure, and still can keep the fire demand water device of certain hour.
The purpose of this utility model is achieved in that this device is made up of fire-fighting jar and nitrogen pressure device.The fire-fighting jar is provided with water level and shows meter, pressure gauge, and the top or the top of jar are provided with the charge valve tube head, and its bottom is provided with the water inlet pipe and water outlet pipe interface, and a jar internal upper part is a nitrogen, and the bottom is a water.The nitrogen pressure device is to be made of the nitrogen cylinder and the pressure reducer that are connected on the bus-bar, and wherein the nitrogen tube on the bus-bar connects with charge valve tube head on being located at the fire-fighting jar, to reach the purpose of inflation pressurization in jar.And the water inlet pipe and water outlet pipe interface of fire-fighting jar bottom communicates with domestic water supplying system and fire hydrant.
The utility model water supply because the bottled nitrogen of employing pressurizes in the fire-fighting jar can not only be alleviated the defective that the pressure-stabilizing water supply system blackout is just cut off the water, and main is to provide emergent alternate source for fire-fighting.In addition, because the equipment of this cover alternate source all is set together with the low level water system with control, this not only is convenient to management and control, and reduced the position height of fire water box, compare with other (as setting up dual power supply or elevated tank) fire protections, not only simple in structure, construction investment is low, and reliable operation safety.
Describe concrete structure of the present utility model and operation principle in detail below in conjunction with drawings and Examples.
Fig. 1 is according to the fire-fighting jar profile in the pressurization by nitrogen gas fire plant that the utility model proposes.
Fig. 2 is the structural representation of nitrogen pressure device.
Fig. 3 is the fundamental diagram of pressurization by nitrogen gas water-supplying device for fire extinguishment and whole water system.
Shown in Figure 1 is the fire-fighting jar of pressurization by nitrogen gas water-supplying device for fire extinguishment.This tank body 1 is the vertical tank that is become by welded steel plate, on tank body 1, have intake valve tube head 2, board-like water level demonstration meter 3, pressure gauge 4, water inlet pipe and water outlet pipe interface 5 and support 6 respectively, wherein tube head 2 can be positioned at the top or the top of jar, interface 5 and support 6 then are positioned at the bottom of tank body 1, but this vertical tank if can correspondingly change the water level meter 3 on the fire-fighting jar, the installation site of pressure gauge 4, charge valve tube head 2 and water inlet pipe and water outlet pipe interface 5, this jar also can be horizontally-arranged.The space that charges into nitrogen is left on top in the tank body 1, and the bottom is a water.
As shown in Figure 2: another part of pressurization by nitrogen gas water-supplying device for fire extinguishment is the nitrogen bus-bar.Bus-bar is made up of bottle stand 7, nitrogen cylinder 8, nitrogen pressure-reducing valve 9 and bus-bar valve 10.Wherein the range of regulation that quantity and pressure-reducing valve 9 are set of nitrogen cylinder 8 is determined by output and pressure of supply water, and join through nitrogen tube that pressure-reducing valve 9 is drawn and the tube head 2 on Fig. 1 fire-fighting jar, after opening nitrogen cylinder 8, nitrogen charges in the tank body 1 through bus-bar valve 10, pressure-reducing valve 9, nitrogen main valve 11 and joint 2, to guarantee in the fire-fighting jar enough pressure being arranged, the water in jar is then incorporated in the water system by Inlet and outlet water interface 5.
Further narrate the operation principle of this fire plant below in conjunction with Fig. 3, share under the situation of pipe network at fire demand water and domestic water, this device is like this work: with feed pump 15 with water storage box 14(or cistern) in water input vacuum tank 17 earlier, owing to have the expansion glued membrane in the vacuum tank 17, when the jar internal pressure increased to certain value, water just entered water supply point 19 and fire hydrant 20.Meanwhile, the water in the system just enters in the fire-fighting jar via non-return valve 12 and Inlet and outlet water interface 5.Injected the water of a certain amount of (generally being not less than 10 minutes water consumptions) when the fire-fighting jar, and the hydraulic pressure of vacuum tank 17 is when having reached the upper limit force value of design, the electric contact pressure meter 18 that is located on the vacuum tank 17 just passes to signal electric cabinet 16, shut down by electric cabinet 16 control feed pumps 15 then, whole like this water system water is just provided by vacuum tank 17.Because the pipeline enclosure of feed pump 15 and fire-fighting jar Inlet and outlet water interface 5, employing be non-return valve 12, and the fire-fighting jar is when supplying water, and 19 of fire hydrants close with valve 13 again, so, the water in the termination of pumping fire-fighting jar also can not flowed out.When the hydraulic pressure in the vacuum tank 17 is lower than lower limit, electric contact pressure meter 18 will send by electric cabinet 16 again and open the pump signal.Under the situation of water system normal power supply, whole system is exactly to carry out pressure-stabilizing water supply in the above described manner.
But in case have a power failure, the condition of a fire perhaps occurs, in the time of must cutting off the electricity supply, as long as open nitrogen cylinder 8, pressure-reducing valve 9 and valve 11 and 13 are just the standby water in the fire-fighting jar can directly enter fire hydrant 20 or incorporate water supply network into.In addition, this fire-fighting jar also can be set up cover waterworks individually, or independent being located in the operating room.
