Description
The present invention relates to a kind of method and system and actuating unit and operating means that hydraulic pressure in the pressure area is carried out closed loop or open loop control.
For the consideration of safety or technical elements, in highrise building, usually press the maximum hydraulic pressure on the standard-required restraint of labour water consumer (for example fire hose or sprinkle fire extinguisher).
If to highly being that fire hose in the 40th floor of 120 m is prepared pressure of supply water, for the consideration of (for example fireman) handling safety aspect, the maximum flowing pressure when water intaking in the underground garage can not surpass 8 bar (Bar) equally so.For protection fireman's consideration, with 80 MPa(8 bar) pressure is defined as the maximum reasonable limiting value.Although for many years from fire fighting equipment, removed these reducing valve according to standard (DIN 1988), usually limited pressure on the fire hose with pressure reducer in the past.
The technical specification of generally acknowledging during according to application, known have following two kinds of dissimilar equipment can limit maximum pressure:
-the first type is that building is divided into a plurality of hydraulic pressure district, lays independently pipeline can for all 10 floors here, gives these piped water supplies by independent supercharging equipment respectively.Can find the design scheme according to prior art in the DIN EN 1988-500 draft standard of publishing in 2008 in annex 1, i.e. design scheme B.
-the second device type is to supply water to building by standpipe, guarantees maximum pressure of supply water by pressure regulator and/or pressure reducer.Can find the design scheme according to prior art in the above-mentioned DIN EN 1988-500 draft standard in annex 1, i.e. design scheme C and/or design scheme D.
But these two types all have shortcoming: the first type of prior art if can not surpass the maximum pressure of regulation, just needs very high material and technical fee owing to needing to prepare a plurality of standpipes and booster pump, and this is just so that these design schemes are very expensive.In the second type, pressure-regulating valve and/or reducing valve are very responsive, are on the hazard thereby may make to supply water.Therefore use it in the fire water equipment very disputablely, should avoid using (with reference to DIN 1988).
In view of the situation, wish to develop a kind of equipment, this equipment provides desirable or required pressure on the one hand working water and/or the fire water equipment of each floor in the high-rise building, but then also can be in the situation that not working pressure adjuster and/or reducing valve only utilize a standpipe and a pump unit to provide required pressure according to corresponding pressure limit.
(control type with reference to the high building drinking water separating station that G tsch, Enrico delivered on May 6th, 2009 on the net according to the solution in a kind of equipment of prior art, network address: " http://www.gep-h2o.de/service/fachbibliothek/fachbeitrag-detail .html beitrag_id=87 "), adopt a certain pressure of supply water of preserving for each floor when triggering the fire water pattern in single channel control situation, this pressure of supply water can provide at required dry point required flowing pressure: roughly need 4.5 bar.When triggering the fire water warning in the 20th floor, pump must produce for example pressure of supply water of 15 bar, could reach 4.5 required bar at the 30th floor.Otherwise when the fire hose in the Underground Garage operatively, pump only need produce for example pressure of supply water of 5 bar, can reach identical flowing pressure.Corresponding value is saved, and in the situation that the value that trigger alarm only need be inquired about this floor on a certain floor.Can realize this point by speed-variable pump in the reality, for example can adopt to have the pump that the frequency conversion three phase alternating current motor drives.
But this way also has the distinct disadvantage the same with above-mentioned way, if put out a fire in the 20th floor, will have simultaneously so the pressure of supply water of 15 bar in underground garage.If fire occurs afterwards in underground garage, the maximum that will substantially exceed 8 bar so here allows flowing pressure.
Except this problem, in this kind equipment, also has fault detection problem.Detect fault (holding wire broken string or the short circuit at normally corresponding water intaking station) at the water intaking station and should cause the pressure of supply water adjustment or be adjusted to being equivalent to the maximum level that allows flowing pressure in this water intaking station, because must consider as far as possible that in this case (i.e. water intaking) provides the corresponding maximum pressure of supply water that allows to this water intaking station for a certain alarm signal.This is justified, because only have in the time of may attacking wire and fetch water the holding wire of standing before fire is detected by (smoke alarm), just will as far as possible at first carry out this fault detect under fire condition.Therefore this fault detect represents to exist the evidence of fire condition, possibly in the mode of corresponding adjustment pressure so that the fire water supply system this is done some preparations, thereby can in the situation that subsequently trigger alarm utilize immediately corresponding pressure of supply water to make a response.
A difficult problem that still exists now is, adjust or regulate hydraulic pressure, so that on the one hand at trigger alarm, namely in the water intaking situation, have the above available with fully (but also being maximum the permission) pressure of supply water of height correlation, also will adjust pressure in perspective mode according to fault detect result (especially according to broken string and/or short circuit recognition result) assurance but then.Why being difficult to accomplish, is because corresponding result also might be mutually relevant.If in the 8th floor, detect fire or the fire fighting water system has here sent warning, then caused water intaking at the 8th floor, when fire is attacked holding wire, may cause fault detect at other floor fully so.
Therefore with regard to the prior art background that above-mentioned G tsch announced on May 6th, 09, task of the present invention is to provide a kind of method and system that hydraulic pressure in the pressure area is carried out closed loop or open loop control, wherein, even can the cheap single channel equipment of use cost in the situation that fetch water simultaneously also according to the maximum flowing pressure limit on the different floor, and on the one hand can guarantee high as far as possible fire-fighting safety in the mode of making every effort to observe maximum pressure limitation, but then also can be with detection failure, especially in the mode of identification broken string or short circuit hydraulic pressure is carried out preventative adjustment.
Adopt the described method of the hydraulic pressure in pressure area being carried out to closed loop or open loop control of claim 1, can solve this task, described method is the same with the method that above-mentioned G tsch announced on May 6th, 09, after on the water intaking station, water intaking or fault being detected, at least according to the geodetic altitude at water intaking station, adopt the pump of the pump supplied water in the water intaking station to drive rotating speed and carry out the mode that closed loop or open loop are controlled, the maximum of adjusting corresponding water intaking station allows the pressure of supply water set-point to make flowing pressure be adapted to this water intaking station, but the invention is characterized in
-in the situation that at least another water intaking station detect water intaking,
New pressure of supply water is adjusted into the maximum that detects another water intaking station of fetching water allows the pressure of supply water set-point,
If-do not detect before water intaking, in the situation that another water intaking station detects fault at least,
New pressure of supply water is adjusted into the minimum pressure of supply water set-point at all water intaking stations that detect fault.
Also can be respectively adopt the pump of the supply-water pump 4 that water intaking station 2,2a are supplied water to drive the mode that rotating speed carries out closed loop or open loop control according to the geodetic altitude 9 of corresponding water intaking station 2,2a at least and adjust new pressure of supply water.
If detect another water intaking, then new pressure of supply water is adjusted into the maximum permissible value at another water intaking station.
If instead continue to detect fault (for example broken string, short circuit) and do not find before (detecting) water intaking, then new pressure of supply water is adjusted into the minimum pressure of supply water set-point at all water intaking stations that detect fault.
The maximum that new pressure of supply water can be adjusted in this case the extreme lower position water intaking station that detects fault allows the pressure of supply water set-point.If at the 50th floor, then at the 4th floor, then in the 3rd floor, detect fault, in any one floor, do not detect water intaking before, and the target flowing pressure in each floor is 4.5 bar, then can be according to suitable adjustment pressure of supply water of the present invention, make its flowing pressure that produces 4.5 bar at the 3rd floor, and produce smaller flowing pressure on the floor in the above.Can in described embodiment, operate fire water equipment by this way, thereby set the rotary speed setting value of pump drive in the time of can in underground garage, fire occurring, so that pump only produces the pressure (pressure of supply water) that can form 8 bar flowing pressures rather than produce 15 bar flowing pressures in underground garage.To consider consciously that at this flowing pressure for fire extinguishing descends at higher floor.The water intaking place of water intaking place afterwards before having precedence over because should be taken into account in practice to put out a fire during the water intaking place finally, water intaking place before shifts, should guarantee fire-fighting safety by readjusting hydraulic pressure now.
Method of the present invention also can guarantee because detecting fault hydraulic pressure to be carried out perspective adjustment, method is that the hydraulic pressure in the water intaking place of at first having found fault is adjusted, because consider here or neighbouringly may have burning things which may cause a fire disaster, and consider most possibly and here put out a fire, namely water intaking.
Trigger alarm is namely fetched water to have precedence over all the time according to the fault detect result and is adjusted hydraulic pressure, because should have the maximum flowing pressure that allows can supply to be used for as far as possible effectively stamping out a fire in the water intaking place.
Can set the rotating speed of pump drive, pump curve is kept among the memory for the computer system of carrying out the method for the invention, thereby can determine corresponding rotating speed for any setting pressure of supply water.Do not need in this case to measure pump pressure with sensor independently, namely pressure of supply water (operating pressure of=pressure area).But also can select to measure pressure of supply water (pressure that namely produces in the pressure area by pump) by means of pressure sensor, and can be with the rotary speed setting value of pump drive as the control variables of adjusting hydraulic pressure.
Preferably, not only according to geodetic altitude, and adjust pressure of supply water according to loss due to duct friction, for example can calibrate the water distributing equipment, and the value that finds in the pressure of supply water value that each floor is preserved takes in.
Can detect wherein with different modes and method and fetch water on the some water intakings station, for example can by means of a kind of measuring cell that can trigger when the manual operation dry point, perhaps adopt a kind of measuring cell that can when reaching and/or surpass certain water volume flow, trigger.Also can detect the fault on the water intaking station, the fault of the corresponding measuring cell that namely water intaking is stood, such as short circuit or disconnection fault can use normally closed interlock to substitute normally open contact.
If satisfy the requirement of DIN 14462 standards, must check one by one then whether all measuring cells break, short circuit and trigger alarm: such as certain dry point of manual operation or reach and/or surpass certain water volume flow.
Can as common mode, utilize a kind of speed governing (saying more accurately brushless) direct drive electrode as pump drive, the rotating speed of pump (more precisely pump drive) is carried out open loop or closed-loop control.But usually preferentially adopt at present the frequency-changing AC drive motors as pump drive.
Adopt method of the hydraulic pressure in the pressure area being carried out closed loop or switch control of the present invention, can adjust pressure of supply water for the situation of pressure decreased, (at least also can) in the following ways: so that actuator or adjuster preferably draining valve be held open or so that the step-down pump continues step-down always always, until reach or be lower than new pressure of supply water.
About removing method of the hydraulic pressure in the pressure area being carried out closed loop or open loop control of the present invention, should note stop that all water intakings detect and the station that stops to fetch water on all fault detects after, pressure of supply water be adjusted into be equivalent to maximum set-points that allow pressure of supply waters (maximum that is generally water intaking station, extreme higher position allows pressure of supply water) in all water intaking stations in the pressure area.If it is 20.5 bar that building has the maximum allowble pressure of 20 floors and the 20th floor, 20.5 bar standby pressures are adjusted to the pressure of supply water in the pressure area in then all detections in stopping all floors (fault detect and water intaking detect) afterwards, like this in the most disadvantageous situation, for example breaking out of fire in the 20th floor will have sufficient flowing pressure available on the dry point here immediately.
The method that the present invention is described here is problem in the situation that those long especially standpipes of use (high buildings and large mansions) may become, because for for following pipe section, the pressure in the standpipe will become quite high owing to water column.Be difficult in this case to reduce rapidly ducted pressure of supply water by means of drain valve and reach the maximum flowing pressure that allows, because the decline of water column (certainly wanting the high drain valve of use cost) may continue for some time, this might be oversize for lower zone.In having the conventional-type system of a plurality of pressure areas, usually this problem can not occur, because building can be divided into different pressure areas here, thereby limit the height of each standpipe.
Therefore in situation of the present invention, can carry out method of the present invention with a kind of decompressor, this decompressor is through design, so that feed pipe namely standpipe have at least one flap valve, this flap valve can be opened in the water (flow) direction that is directed upwards towards dry point from the hydraulic pressure source, and in the opposite direction only similar closed, because this valve has one through the opening of design, so that water can pass through in the direction opposite with above-mentioned flow direction under Action of Gravity Field, so that be positioned at the feed pipe zone (observing at flow direction upwards) of flap valve back can not be subject to exceeding the pressure outside the pressure that gravity causes when flap valve is closed effect.The compression coefficient of water very little (being 0.00021 m3/m3 K under 20 ° of C temperature), diameter is not more than 10 mm in the valve, the small sircle hole that particularly preferably is not more than 5 mm just is enough to so that water refluxes under Action of Gravity Field, thereby reduces pressure at a terrific speed.If be not that opening is designed to circular hole, namely it is not designed to boring, then substitute the opening size that represents with diameter with other geometry opening cross sectional area that equals (roughly) the circular hole area.
If water pipe (namely standpipe) is long, then can adopt the flap valve a plurality of separated by a distance of type of the present invention, by the pressure that causes owing to water column in the pipe in these flap valve restriction corresponding segment, because these valves only have very little opening at (returning) flow path direction that gravity produces.
Only for for the purpose of the integrality, should be mentioned in that be the present invention here described decompressor be not only can use with the present invention method and actuating unit thereof described here, but also can independently represent in liquid conducting pipes, the independent invention of especially in standpipe, reducing pressure, because can in a row be arranged among the pipeline successively separately or separated by a distance, can in pipeline, realize reduction of blood pressure in high-speed, also not have very high liquid (especially water) displaced volume flow.
Above all embodiments that hydraulic pressure in the pressure area carried out the method for closed loop or open loop control of the present invention all can move in the computer system of process relative set, described computer preferably has to control the interface rotary speed setting value of pump drive (be set) of actuator here, and/or have to read in the interface (being such as pressure sensor, water ga(u)ge or water intake valve sensor) of measured value or sensor states here.Method of the present invention also can be used as Downloadable computer program, for example is present on data medium or the electrical carrier signal.
Can make up a kind of according to open loop or the closed ring hydraulic pressure control system that the hydraulic pressure in the pressure area is carried out closed loop or open loop control of the present invention by means of unify corresponding measuring cell and/or executing agency's (actuator and/or sensor) of this department of computer science, described control system has a computer system that arranges as previously mentioned, and adopt the detector that detects water intaking or fault at the water intaking station, be connected to computer system by the interface that is used for connecting a detector or a plurality of detectors.Also adopt a pump of standing and supplying water and have pump drive to water intaking in this external this system, can be by being used for the rotating speed of interface setting pump drive of output speed set-point, computer system links to each other with pump drive by being used for the interface of output speed set-point.System of the present invention also preferably has a pressure sensor, and this sensor can be measured corresponding pressure of supply water (being also referred to as pump pressure), namely measures the operating pressure that pump causes in the pressure area.
Closed loop of the present invention or open loop water pressure control system are used for that preferably the floor at least one residence space especially is arranged in (around the high building), and above the ground the industrial water use of the high building more than 22 meters and/or drinking water supply hydraulic pressure carry out closed loop or open loop control.Described high building particularly preferably only has a unique pressure area that is used for water supply, namely only has a unique industrial water use water supply standpipe and/or a unique drinking water water supply standpipe.But what must mention is, have among (king-sized) building of a plurality of pressure areas, if building is for a unique pressure area and Yan Taida, in the situation that namely pressure on must the dry point in low floor can not become too high, when the distance between parallel two floors that supply water becomes too large mutually, also can use system of the present invention (the same with method of the present invention).In this case, the present invention can reduce the quantity of pressure area, because the present invention can arrange this quantity, thereby just can give mutually parallel water supply of two different floors, and the pressure on the low floor can not become too high at the dry point place, perhaps the pressure on the higher floor can not become too low.
Especially in high building, particularly preferably use the present invention as closed loop or the open-loop control system of fire water supply hydraulic pressure.In this case, the fire water network of high building also can only have a unique pressure area.If it is too large that pressure still becomes, also the present invention can be used for reducing at least the quantity of pressure area under the so this mode of occupation, this is the same with above-mentioned situation for industrial water use and/or drinking water supply.
Below will describe with reference to the accompanying drawings a kind of specific embodiment, but the present invention should not be limited to this embodiment and understands.Accompanying drawing is as follows:
Accompanying drawing 1 is the vertical section schematic diagram that a building only has the 50th floor height buildings in a fire water pressure district, has wherein used one embodiment of the present invention,
Accompanying drawing 2 is the longitudinal plans with a kind of standpipe according to decompressor embodiment of the present invention, and
Accompanying drawing 3 is one and has another according to the longitudinal plan of the standpipe of decompressor embodiment of the present invention.
Accompanying drawing 1 is the vertical vertical section schematic diagram that a building only has the 50th floor height buildings in a fire water pressure district, one embodiment of the present invention have wherein been used, high building 1 has the subterranean layer and 50 the floor OG that contain underground garage T, does not draw one by one all floors wherein.
In subterranean layer, also be provided with a water intaking station 2a among underground garage T.Computer system 5 can be by programming according to the method described in the present invention accordingly, and the fire water equipment according to the present invention to high building 1 carries out open loop or closed-loop control.
When triggering the fire water pattern, adopt for each floor preservation pressure of supply water and (be also referred to as pump pressure, the hydraulic pressure that produces in the pressure area of pump namely), this pressure of supply water provides desired flowing pressure-roughly require 4.5 bar at required dry point 2,2a.Report to the police if after this send fire water in the 50th floor 50.OG, then pump 4 must produce for example pressure of supply water of 20.5 bar, in order to reach desired 4.5 bar pressures at the 50th floor 50.OG.If instead operation fire hose 2a in underground garage T, then pump 4 is as long as form for example pressure of supply water of 5 bar, in order to reach 4.5 same bar flowing pressures here.Corresponding value is saved, and in the situation that some floor OG send warning only by computer 5 value that (internal memory and/or mass storage) inquires about this floor in memory, then by means of tachometer value pump 4 is carried out corresponding control, if perhaps there has been higher pressure, then open drain valve 11, until reach or (just) is lower than pressure, then again so that pump reaches required tachometer value.
At this moment, if cause occurring subsequently among the underground garage T event of fire after event of fire appears in the 50th floor 50.OG, the maximum that will substantially exceed 8 bar so here allows flowing pressure.
At this moment can adopt the present invention, the maximum that can not only the flowing pressure on corresponding water intaking station 2, the 2a be adjusted into this water intaking station 2 after detecting water intaking allows the hydraulic pressure set-point, can adjust according to 9 pairs of modes of carrying out closed-loop control for the pump drive rotating speed of water intaking station 2 supply-water pumps 4 by standpipe 3 of geodetic altitude at water intaking station 2 among the 50th the floor 50.OG in addition; In addition also can be in the situation that another water intaking station 2a(be here in underground garage T) detect water intaking and adjust the maximum permissible value that flowing pressure makes it to be adapted to detect the water intaking station 2a of (another) water intaking, the mode that also can (at least) adopts rotating speed to pump 4 to carry out closed-loop control according to the geodetic altitude of corresponding water intaking station 2,2a is adjusted, and/or adjust by drain valve 11, and/or adjust by step-down pump (namely adopting the mode of adjusting pressure of supply water).
Here preferably adopt the flap valve 10 of a butterfly shaped check valve form, this flap valve can be directed upwards towards from the hydraulic pressure source water (flow) direction of dry point and open, and in the opposite direction only similar closed, because this valve has the suitably opening of design of a process, so that water can be under Action of Gravity Field pass through along the direction opposite with above-mentioned flow direction, so that be positioned at the feed pipe zone (observing at flow direction upwards) of flap valve back can not be subject to exceeding the pressure outside the pressure that gravity causes when flap valve is closed effect.Therefore in the 50th floor 50.OG, set up after the pressure of supply water at water intaking station, can pressure of supply water be reduced to by means of a simple drain valve level of underground garage T, needn't use the expensive industrial valves with very large cross section.
So can proper handling fire water equipment, thus suitably set the rotary speed setting value of pump drive in the time of can in underground garage T, event of fire occurring, so that pump 4 only produces the pressure of 8 bar rather than 15 bar in underground garage T.Consider consciously that at this flowing pressure that is used for fire extinguishing among the 50th floor 50.OG descends, because at a time usually only have a fire extinguishing place.
Accompanying drawing 2 is depicted as a longitudinal plan with a kind of standpipe according to decompressor embodiment of the present invention.Standpipe 3(feed pipe) has a flap valve 10, here be a cover plate 13 that can move within the specific limits at the axial direction of water pipe 3 along guiding device 12, the water (flow) direction 14a that this flap valve can be directed upwards towards from the hydraulic pressure source dry point opens, because can force cover plate 13 upwards to move towards pillar 12b by pressure of supply water, thereby will be closed towards the segmentation of the pipeline 3 of this direction, and it is only almost closed to be in the rightabout 14b place that the pipe section in this direction hides fully at cover plate, because adopted the suitably opening 15 of design of a process, so that water can pass through in the direction opposite with above-mentioned flow direction 14a under Action of Gravity Field, so that feed pipe 3 zones (observing at flow direction 14a upwards) that are positioned at flap valve 10 back can not be subject to the effect of the pressure outside the pressure that gravity causes when flap valve 10 is closed.
Accompanying drawing 3 is depicted as one and has another kind according to the longitudinal plan of the standpipe of decompressor embodiment of the present invention.Here can see also that a feed pipe 3(equally also is standpipe here), this feed pipe has a flap valve 10, this flap valve can be opened at the water (flow) direction 14a that is directed upwards towards dry point from the hydraulic pressure source, namely can be around the valve block 13a of axle 12c swing by means of one, here also preferably towards pillar 12b compressing valve block, it is opened more than 90 ° at least, and can make it remain closed by hydraulic pressure, and 14b place in the opposite direction, the valve block 13a that does not have complete vertical unlocking by the water of downward outflow to lower compression, and therefore and only similar closed.Because the suitably opening 15 of design of a process is arranged, so that water can pass through in the direction opposite with above-mentioned flow direction 14a under Action of Gravity Field, so that feed pipe 3 zones (observing at flow direction 14a upwards) that are positioned at flap valve 10 back can not be subject to the effect of the pressure outside the pressure that gravity causes when flap valve 10 is closed.
