Description
The present invention relates to a kind of method and system and actuating unit and operating means that hydraulic pressure in pressure zone is carried out to closed loop or open loop control.
For the consideration of safety or technical elements, in skyscraper, conventionally press for example, maximum hydraulic pressure on standard-required restriction work water consumer (fire hose or sprinkle fire extinguisher).
If to being highly that fire hose in the 40th floor of 120 m is prepared pressure of supply water, for example, for the consideration of (fireman) handling safety aspect, the maximum flowing pressure in the time of water intaking in underground garage can not exceed 8 bar (Bar) equally so.For protection fireman's consideration, by 80 MPa(8 bar) pressure is defined as maximum reasonable ultimate value.Although for many years removed these reduction valve according to standard (DIN 1988) from fire fighting equipment, conventionally limited the pressure on fire hose with decompressor in the past.
According to generally acknowledged technical manual of when application, known have following two kinds of dissimilar equipment can limit maximum pressure:
-the first type is that buildings is divided into multiple hydraulic pressure district, lays independently pipeline can to all 10 floors here, gives these piped water supplies respectively by independent pressure generating equipment.In the DIN EN 1988-500 draft standard of publishing for 2008 in annex 1, can find the design proposal according to prior art, i.e. design proposal B.
-the second device type is to supply water to buildings by standpipe, ensures maximum pressure of supply water by pressure governor and/or decompressor.In above-mentioned DIN EN 1988-500 draft standard in annex 1, can find the design proposal according to prior art, i.e. design proposal C and/or design proposal D.
But these two types all have shortcoming: the first type of prior art, because needs are prepared multiple standpipes and supercharge pump, if can not exceed the maximum pressure of regulation, just needs very high material and technical fee, and this just makes these design proposals very expensive.In the second type, pressure-regulating valve and/or reduction valve are very responsive, are on the hazard thereby may make to supply water.Therefore use it in fire water equipment very disputable, should avoid use (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 high-rise, also can, the in the situation that of working pressure regulator not and/or reduction valve, only utilize a standpipe and a pumping unit to provide required pressure according to corresponding pressure limit but then.
According to (the high building potable water separating station control type of delivering on the net on May 6th, 2009 with reference to G tsch, Enrico of 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 "), trigger fire water pattern in single channel control situation time, adopt a certain pressure of supply water of preserving for each floor, this pressure of supply water can provide required flowing pressure at required dry point: roughly need 4.5 bar.In the time triggering fire water warning in the 20th floor, pump must produce for example pressure of supply water of 15 bar, could on the 30th floor, reach 4.5 required bar.Otherwise in the time of fire hose in Underground Garage operatively, pump only needs to produce for example pressure of supply water of 5 bar, can reach identical flowing pressure.Corresponding value is saved, and the value that only needs to inquire about this floor trigger alarm in the situation that on a certain floor.In reality, can realize this point by speed-variable pump, for example can adopt and there is the pump that 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 underground garage, will there is so the pressure of supply water of 15 bar in the 20th floor simultaneously.If there is afterwards fire 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.On water intaking station, detect that fault (signal wire broken string or the short circuit at normally corresponding water intaking station) should cause 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 alerting signal.This is justified, because only have when may attacking wire and fetch water the signal wire of standing before fire being detected by (smoke alarm), just will under fire condition, as far as possible first carry out this fault detect.Therefore this fault detect represents to exist the evidence of fire condition, in the mode of corresponding adjustment pressure, fire water supply system is done some preparations to this possibly, thereby can the in the situation that of trigger alarm subsequently, utilize immediately corresponding pressure of supply water to make a response.
The difficult problem still existing is now, adjust or regulate hydraulic pressure, to make on the one hand at trigger alarm, namely to have the above available with fully (but being also maximum permission) pressure of supply water of height correlation, also to adjust pressure in perspective mode according to fault detect result (especially according to broken string and/or short circuit recognition result) guarantee but then in water intaking situation.Why being difficult to accomplish, is because corresponding result is also likely mutually relevant.If detect fire in the 8th floor or the fire fighting water system here has sent warning, on the 8th floor, cause water intaking, in the time that fire is attacked signal wire, may on other floor, cause fault detect completely so.
Therefore with regard to above-mentioned G tsch on May 6th, 09 announce prior art background with regard to, task of the present invention is to provide a kind of method and system that hydraulic pressure in pressure zone is carried out to closed loop or open loop control, wherein, even also can the cheap single channel equipment of use cost in the situation that of water intaking according to the maximum flowing pressure limit on different floors simultaneously, and on the one hand can be to make every effort to ensureing high as far as possible fire-fighting safety in accordance with the mode of 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 to preventative adjustment.
The method of described in employing claim 1, the hydraulic pressure in pressure zone being carried out to closed loop or open loop control, can solve this task, described method is the same with the method that above-mentioned G tsch announced on May 6th, 09, water intaking or fault detected on water intaking station after, the mode that at least adopts the pump of the pump being supplied water in water intaking station to drive rotating speed to carry out closed loop or open loop control according to the geodetic altitude at water intaking station, the maximum of adjusting corresponding water intaking station allows 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 detects water intaking on standing,
New pressure of supply water is adjusted into and detects that the maximum at another water intaking station of fetching water allows pressure of supply water set-point,
-if water intaking do not detected before, in the situation that at least another water intaking detects fault on standing,
New pressure of supply water is adjusted into the minimum pressure of supply water set-point at all water intakings station that fault detected.
The mode that also can at least adopt the pump of the make-up pump 4 that water intaking station 2,2a are supplied water to drive rotating speed to carry out closed loop or open loop control according to the geodetic altitude 9 of corresponding water intaking station 2,2a is respectively adjusted new pressure of supply water.
If another water intaking detected, new pressure of supply water is adjusted into the maximum permissible value at another water intaking station.
For example, if instead continue to detect fault (broken string, short circuit) and do not find before (detecting) water intaking, new pressure of supply water being adjusted into the minimum pressure of supply water set-point at all water intakings station that fault detected.
The maximum that new pressure of supply water can be adjusted in this case to the extreme lower position water intaking station that fault detected allows pressure of supply water set-point.If at the 50th floor, then at the 4th floor, then fault detected in the 3rd floor, in any one floor, water intaking do not detected before, and the target flowing pressure in each floor is 4.5 bar, can be according to suitable adjustment pressure of supply water of the present invention, make its flowing pressure that produces 4.5 bar on the 3rd floor, and produce smaller flowing pressure on floor in the above.Can in described embodiment, operate by this way fire water equipment, thereby can there is fire in underground garage time, set the rotary speed setting value of pump drive, pump is only produced can in underground garage, form 8 bar flowing pressures instead of produce the pressure (pressure of supply water) of 15 bar flowing pressures.To consider consciously that at this flowing pressure for putting out a fire declines at higher floor.The water intaking place of water intaking place afterwards before having precedence over, because should be taken into account in practice from putting out a fire during water intaking place finally, water intaking place before and shift, should ensure fire-fighting safety by readjusting hydraulic pressure now.
Method of the present invention also can ensure, because fault being detected, hydraulic pressure is carried out to perspective adjustment, method is that the hydraulic pressure in the water intaking place to 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 fault detect result and is adjusted hydraulic pressure, because should there be the maximum flowing pressure that allows can supply to be used for as far as possible effectively stamping out a fire in water intaking place.
Can set the rotating speed of pump drive, pump curve is kept among the storer of the computer system for 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, namely pressure of supply water (working pressure of=pressure zone) with sensor independently.But also can select to measure pressure of supply water (pressure producing in pressure zone by pump) by means of pressure transducer, and can be using the rotary speed setting value of pump drive as the control variable 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 water distributing equipment, and the value finding in the pressure of supply water value that each floor is preserved takes in.
Can detect wherein and fetch water on some water intakings station by different modes and method, for example can be by means of a kind of measuring sensor that can trigger when the manual operation dry point, or adopt a kind of measuring sensor that can trigger in the time reaching and/or exceed certain water volume flow.Also can detect the fault on water intaking station, the namely fault of the corresponding measuring sensor at water intaking station, such as short circuit or disconnection fault, can be used normally closed interlock to substitute normally open contact.
If meet the requirement of DIN 14462 standards, must check one by one whether all measuring sensors break, short circuit and trigger alarm: such as certain dry point of manual operation or reach and/or exceed certain water volume flow.
Can be 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 to open loop or closed-loop control.But conventionally preferentially adopt at present frequency-changing AC drive motor as pump drive.
Adopt method of the hydraulic pressure in pressure zone being carried out to 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: make actuator or regulator preferably draining valve be held open always or make step-down pump to continue step-down always, until reach or lower than new pressure of supply water.
About removing method of the hydraulic pressure in pressure zone being carried out to closed loop or open loop control of the present invention, should note after all water intakings detect and stop all fault detects on water intaking station, pressure of supply water being adjusted into and being equivalent to the maximum set-point that allows pressure of supply water (maximum that is generally water intaking station, extreme higher position allows pressure of supply water) in all water intakings station in pressure zone stopping.If it is 20.5 bar that buildings has the maximum allowble pressure of 20 floors and the 20th floor, afterwards the pressure of supply water in pressure zone is adjusted to 20.5 bar standby pressures in all detections (fault detect and water intaking detect) that stop in all floors, 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 present invention's method (high buildings and large mansions) in the situation that of those uses especially long standpipe described here may become problem, because for the pipe section far away from below, the pressure in standpipe will become quite high due to water column.Be difficult in this case to reduce rapidly ducted pressure of supply water by means of bleed valve and reach the maximum flowing pressure that allows, because the decline of water column (certainly wanting the high bleed valve of use cost) may continue for some time, this is likely oversize for lower zone.In the conventional-type system with multiple pressure zones, conventionally there will not be this problem, because buildings can be divided into different pressure zones here, thereby limited the height of each standpipe.
Therefore in situation of the present invention, can carry out method of the present invention with a kind of reliever, this reliever is through design, make feed pipe namely standpipe there is at least one non-return valve, this non-return valve can be opened in the water (flow) direction that is directed upwards towards dry point from hydraulic pressure source, and in the opposite direction only similar closed, because this valve has an opening through design, water can be passed through in the direction contrary with above-mentioned flow direction under Action of Gravity Field, in the time that non-return valve is closed, can not be subject to exceeding the effect of the pressure outside the pressure that gravity causes to make to be positioned at feed pipe region after non-return valve (observing at flow direction upwards).The compressibility coefficient very little (being 0.00021 m3/m3 K at 20 ° of C temperature) of water, in valve, diameter is not more than 10 mm, the small sircle hole that is particularly preferably not more than 5 mm is just enough to make water to reflux under Action of Gravity Field, thereby reduces pressure at a terrific speed.If not opening is designed to circular hole, be not namely designed to boring, substitute with other geometric configuration opening cross sectional area that equals (roughly) circular hole area the opening size representing with diameter.
If water pipe (namely standpipe) is long, can adopt the non-return valve multiple separated by a distance of type of the present invention, by the pressure causing due to the interior water column of pipe in these non-return valve restriction corresponding segment, because (returning) flow path direction that these valves only produce at gravity has very little opening.
Only for the purpose of integrality, what should be mentioned in that is to use together with the present invention's method that here described reliever not only can be described here with the present invention and actuating unit thereof, but also can independently represent the independent invention of reducing pressure at liquid conducting pipes, especially in standpipe, because can in a row be arranged in successively among pipeline separately or separated by a distance, can in pipeline, realize reduction of blood pressure in high-speed, also there is no very high liquid (especially water) withdrawal volume flow.
All embodiments of method of the hydraulic pressure in pressure zone being carried out to closed loop or open loop control of the present invention all can move through in the computer system of relative set above, described computing machine preferably has the interface (being the rotary speed setting value of setting pump drive) for controlling actuator here, and/or has the interface (being such as pressure transducer, water ga(u)ge or water intake valve sensor) for reading in measured value or sensor states here.Method of the present invention also can be used as Downloadable computer program, is for example present in data carrier or electrical carrier signal.
Can build a kind of according to open loop or the closed ring hydraulic pressure control system that the hydraulic pressure in pressure zone is carried out to closed loop or open loop control of the present invention by means of unify corresponding measuring sensor and/or topworks's (actuator and/or sensor) of this department of computer science, described control system has a computer system arranging as previously mentioned, and adopt the detecting device that detects water intaking or fault on water intaking station, be connected to computer system by the interface that is used for connecting a detecting device or multiple detecting devices.In this external this system, also adopt a pump that supplies water to water intaking station and there is pump drive, can be by being used for the rotating speed of interface setting pump drive of output speed set-point, computer system is connected with pump drive by being used for the interface of output speed set-point.System of the present invention also preferably has a pressure transducer, and this sensor can be measured corresponding pressure of supply water (also referred to as pump pressure), namely measures the working pressure that pump causes in pressure zone.
Closed loop of the present invention or open loop water pressure control system are preferably used for that the floor at least one residence space is especially arranged in to (around high building), and above the ground process water and/or the drinking water supply hydraulic pressure of 22 meters of above high buildings carry out closed loop or open loop control.Described high building particularly preferably only has a unique pressure zone for supplying water, namely only has a unique process water water supply standpipe and/or a unique potable water water supply standpipe.But what must mention is, have among (king-sized) buildings of multiple pressure zones, if buildings is for a unique pressure zone and Yan Tai great, namely the pressure on must the dry point in lower floor can not become too high, when 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 zone, because the present invention can arrange this quantity, thereby just can give two different floors parallel water supply mutually, and it is too high that the pressure on lower floor can not become at dry point place, or pressure in higher floor can not become too low.
Especially in high building, particularly preferably use closed loop or the open-loop control system of the present invention as fire water supply hydraulic pressure.In this case, the fire water network of high building also can only have a unique pressure zone.If it is too large that pressure still becomes, under so this service condition, also the present invention at least can be used for reducing the quantity of pressure zone, this is the same with the above-mentioned situation for process water 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 longitudinal profile schematic diagram that a building only has the 50 floor height buildings in a fire water pressure district, has wherein used one embodiment of the present invention,
Accompanying drawing 2 be one have a kind of according to the longitudinal diagram of the standpipe of reliever embodiment of the present invention, and
Accompanying drawing 3 is one and has another according to the longitudinal diagram of the standpipe of reliever embodiment of the present invention.
Accompanying drawing 1 is the vertical longitudinal profile schematic diagram that a building only has the 50 floor height buildings in a fire water pressure district, one embodiment of the present invention are wherein used, high building 1 has subterranean layer and 50 the floor OG containing underground garage T, does not draw one by one all floors wherein.
On each floor OG, all have water intaking station 2, these water intaking stations are all connected to a unique common water lines 3,3a(leads to floor OG above as standpipe 3), supply water to water intaking station 2 from the pump 4 that is arranged in subterranean layer by this pipeline.Pump 4 has a pump drive that rotating speed is adjustable, and computer system 5 can be controlled this pump drive by being used for the interface of output speed set-point 6.In addition computer system (computing machine) 5 is also connected to for detecting on the detecting device 7 of water intaking at water intaking station 2,2a place by an interface.This interface 7 is connected with the corresponding detecting device on dry point 2,2a, thereby the trigger pip of detecting device can be sent to computer system 5 by signal wire 8,8a.Preferably these signal wires 8,8a are and are star connected to computing machine 5, whether especially preferably monitor these signal wires breaks and/or short circuit, for example can use corresponding path monitoring model (a kind of model that comprises resistor network, for example Walluszek GmbH, the circuit monitoring system of 01591 Riesa company).Preferably as far as possible jointly be laid among a bunch of cables or by its adjacent being laid on same cable testing bridge being signal wire 8,8a that star leads to detecting device from computing machine 5, make the fire in a certain place roughly attack signal wire simultaneously.If this thing happens, will detect all wires is all short circuit and/or broken string, namely detects a fault.According to of the present invention, this will cause pressure of supply water (as long as water intaking not detected before) to be adjusted into the minimum hydraulic pressure set-point at the water intaking station that fault detected.If for example second and the 3rd floor 2.OG, 3.OG between on fire, so after the short time, all signal wires 8 of second floor 2.OG top all will send the signal that produces fault, because the fire here will be attacked all these wires, then cause short circuit or (afterwards) even to break.Otherwise the wire of first and second floor 1.OG, 2.OG still keeps not damaged.Now, can suitably adjust pressure of supply water according to the computing machine 5 of the method for the invention operation, make it equal pressure of supply water set-point, this set-point is equivalent to the minimum hydraulic pressure set-point at the water intaking station that fault detected.The minimum hydraulic pressure set-point that the water intaking station of fault detected is exactly the hydraulic pressure set-point of the 3rd floor 3.OG in this case.Pressure of supply water is adjusted to this value like this, then just can use for the fire-fighting operation here.Except traditional star signal wire lay with the broken string of common type/short circuit monitoring, naturally also can select modern bus system, this bus system for example has regularly by bus to control center, namely sends active signal detecting device and/or other active signal element of standby ready signal to computing machine 5.If lack this standby ready signal (being similar to secured pushbutton switch) within a certain fixing setting period, there is certain fault in this position, and for example broken string, short circuit or signal detector are malfunctioning.If signal detector is connected to control center by second other signal bus in another independently, is namely arranged on the circuit on other space path in addition, can whether be so just that this circuit produces fault (broken string or short circuit) or detecting device produces fault with very high probability difference.If detecting device is only logined on one of them signal wire of two signal wires, another circuit has fault; If divide on the circuit being arranged and all do not login in two spaces, detecting device itself probably exists in the surrounding environment of fault or detecting device and has event of failure (such as fire).
In subterranean layer, be also 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.
In the time triggering fire water pattern, adopt for each floor and preserve pressure of supply water (also referred to as pump pressure, the hydraulic pressure that namely pump produces in pressure zone), 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, pump 4 must produce for example pressure of supply water of 20.5 bar, to reach desired 4.5 bar pressures at the 50th floor 50.OG.If instead operate fire hose 2a in underground garage T, pump 4 is as long as form for example pressure of supply water of 5 bar, to reach 4.5 same bar flowing pressures here.Corresponding value is saved, and the value that only (internal memory and/or mass storage) inquires about this floor in storer by computing machine 5 in the situation that some floor OG send warning, then by means of tachometer value, pump 4 is carried out to corresponding control, if or there is higher pressure, open bleed valve 11, until reach or (just) lower than pressure, then again make pump reach required tachometer value.
Now, if there is subsequently event of fire cause underground garage T after event of fire appears in the 50th floor 50.OG in, 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 2,2a be adjusted into this water intaking station 2 after water intaking being detected allows hydraulic pressure set-point, can adjust the mode of carrying out closed-loop control to by standpipe 3 the pump drive rotating speed of water intaking station 2 make-up pumps 4 according to the geodetic altitude 9 at water intaking station 2 in the 50th floor 50.OG in addition; In addition can be also here in underground garage T at another water intaking station 2a() adjust flowing pressure water intaking detected in the situation that and make it to be adapted to the maximum permissible value of the water intaking station 2a that (another) water intaking detected, also can (at least) adopt the mode that the rotating speed of pump 4 is carried out to closed-loop control to adjust according to the geodetic altitude of corresponding water intaking station 2,2a, and/or adjust by bleed valve 11, and/or adjust by step-down pump (namely adopting the mode of adjusting pressure of supply water).
Here preferably adopt the non-return valve 10 of a butterfly shaped check valve form, this non-return valve can be directed upwards towards from hydraulic pressure source the 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, water can be under Action of Gravity Field be passed through along the direction contrary with above-mentioned flow direction, in the time that non-return valve is closed, can not be subject to exceeding the effect of the pressure outside the pressure that gravity causes to make to be positioned at feed pipe region after non-return valve (observing at flow direction upwards).Therefore set up the pressure of supply water at water intaking station in the 50th floor 50.OG after, can pressure of supply water be reduced to by means of a simple bleed valve to the level of underground garage T, needn't use the expensive industrial valves with very large transversal section.
So just energy proper handling fire water equipment, thus the suitable rotary speed setting value of setting pump drive can there is event of fire in underground garage T time makes pump 4 in underground garage T, only produce the pressure of 8 bar instead of 15 bar.Consider consciously in the 50th floor 50.OG and decline for the flowing pressure of putting out a fire at this, because at a time conventionally only have a fire extinguishing place.
Attachedly Figure 2 shows that one has a kind of according to the longitudinal diagram of the standpipe of reliever embodiment of the present invention.Standpipe 3(feed pipe) there is a non-return valve 10, here be a cover plate 13 that can move within the specific limits at the axial direction of water pipe 3 along guide piece 12, the water (flow) direction 14a that this non-return valve can be directed upwards towards from hydraulic pressure source dry point opens, because can force cover plate 13 upwards to move towards pillar 12b by pressure of supply water, thereby by the segmentation closure of the pipeline towards this direction 3, and the reverse direction 14b place pipe section being in this direction being hidden completely at cover plate is only almost closed, because adopted the suitably opening 15 of design of a process, water can be passed through in the direction contrary with above-mentioned flow direction 14a under Action of Gravity Field, in the time that non-return valve 10 is closed, can not be subject to the effect of the pressure outside pressure that gravity causes to make to be positioned at feed pipe 3 regions below of non-return valve 10 (observing at flow direction 14a upwards).
Attachedly Figure 3 shows that one has another kind of according to the longitudinal diagram of the standpipe of reliever embodiment of the present invention.Here also can see that a feed pipe 3(is equally also standpipe here), this feed pipe has a non-return valve 10, this non-return valve can be opened at the water (flow) direction 14a that is directed upwards towards dry point from hydraulic pressure source, by means of a valve block 13a that can swing around axle 12c, here also preferably towards pillar 12b compressing valve block, it is at least opened more than 90 °, and can make it remain closed by hydraulic pressure, and in the opposite direction 14b place, there is no the valve block 13a of complete vertical unlocking to lower compression by the water of downward outflow, and therefore and only similar closed.Because there is the suitably opening 15 of design of a process, water can be passed through in the direction contrary with above-mentioned flow direction 14a under Action of Gravity Field, in the time that non-return valve 10 is closed, can not be subject to the effect of the pressure outside pressure that gravity causes to make to be positioned at feed pipe 3 regions below of non-return valve 10 (observing at flow direction 14a upwards).
