Definitions
- the invention relates to an alarm valve station, in particular a wet alarm valve station, a fire extinguishing system, with an alarm valve with an extinguishing fluid inlet and an extinguishing fluid outlet, the alarm valve having a closing body which can be moved back and forth between a locked state and a released state, the fluid inlet chamber and the fluid outlet chamber being separated from one another in the locked state and communicate fluidly with one another in the release state, an alarm triggering device for triggering a fire alarm, which is connected to the alarm valve, and a delay tank for delaying the triggering of the fire alarm, the alarm valve being fluidly connected to a fluid inlet of the delay tank and a fluid outlet of the delay tank with the Alarm triggering device is connected.
- the invention further relates to a fire extinguishing system with such an alarm valve station.
- Alarm valve stations of fire extinguishing systems are used to trigger a fire alarm.
- known alarm valve stations regularly determine the fluid flow of the extinguishing fluid between the extinguishing fluid inlet, which is usually fluidly connected to an extinguishing fluid supply, and the extinguishing fluid outlet, which is usually fluidly connected to a sprinkler arrangement via a fluid line system.
- the sprinkler nozzles of the sprinkler arrangement open so that the pressure level in the line system of the sprinkler arrangement and thus also at the extinguishing fluid outlet of the alarm valve drops.
- the pressure drop leads to the formation of a pressure difference between the extinguishing fluid inlet and the extinguishing fluid outlet of the alarm valve.
- the closing body arranged in the alarm valve and closed when the alarm valve is in the idle state is opened.
- the extinguishing fluid inflow is released from the inside of the alarm valve, for example into a spur line, which is usually referred to as an alarm line.
- the stub is (almost) fluid-free in the rest position of the closing body and depressurized.
- the spur line is fluidly connected to a pressure sensor which detects the pressure change in the spur line caused by the inflowing extinguishing fluid.
- the pressure sensor is part of an alarm triggering device.
- the extinguishing fluid supply is subject to temporary pressure fluctuations, for example due to water hammer in the supply network.
- the pressure sensor is regularly preceded by a hydraulic delay tank.
- the delay tank only builds up pressure at the pressure sensor, which is evaluated as an event for the generation of an alarm signal when a sufficiently large amount of extinguishing fluid flows into the alarm line or the delay tank and a corresponding pressure builds up at the pressure sensor prevents temporary pressure fluctuations in the extinguishing fluid supply from triggering a fire alarm unintentionally.
- the fluid outlet of known delay tanks is some, as in US2505761 or GB327676 Disclosed, alarm valve stations fluidly connected to several separate components, for example with several different or the same pressure sensors and / or with alarm devices such as alarm bells.
- the delay tank is connected to branch lines which distribute the extinguishing fluid pressure or the extinguishing fluid flow present at the delay tank.
- various fittings are usually used, such as T-shaped or Y-shaped line branches arranged at the fluid outlet of the delay container.
- this causes a high level of assembly and maintenance work, and on the other hand such a line arrangement leads to an increased risk of leakage and thus a functional impairment or even a functional failure.
- DE 10 2007 049 588 A1 relates to a dry alarm valve with the extinguishing fluid outlet an alarm trigger device is connected.
- a delay tank with a fluid inlet and a fluid outlet is arranged between the dry alarm valve and the alarm triggering device.
- the object underlying the invention is to provide a way to fluidly connect the delay tank of an alarm valve station (outlet side) with several separate components, the assembly and maintenance effort and / or the risk of leakage being reduced in comparison to the known solutions and to arrange the delay container within the alarm valve station to save space.
- the object is achieved with an alarm valve station of the type mentioned at the outset, the delay container having a plurality of fluid inlets and / or a plurality of fluid outlets.

Description
Die Erfindung betrifft eine Alarmventilstation, insbesondere Naßalarmventilstation, einer Feuerlöschanlage, mit einem Alarmventil mit einem Löschfluideinlass und einem Löschfluidauslass, wobei das Alarmventil einen zwischen einem Sperrzustand und einem Freigabezustand hin- und her bewegbaren Schließkörper aufweist, wobei die Fluideintrittskammer und die Fluidaustrittskammer im Sperrzustand voneinander getrennt sind und im Freigabezustand fluidleitend miteinander kommunizieren, einer Alarmauslöseeinrichtung zum Auslösen eines Brandalarms, welche mit dem Alarmventil verbunden ist, und einem Verzögerungsbehälter zum Verzögern des Auslösens des Brandalarms, wobei das Alarmventil fluidleitend mit einem Fluideinlass des Verzögerungsbehälters verbunden ist und ein Fluidauslass des Verzögerungsbehälters mit der Alarmauslöseeinrichtung verbunden ist. Die Erfindung betrifft ferner eine Feuerlöschanlage mit einer solchen Alarmventilstation.The invention relates to an alarm valve station, in particular a wet alarm valve station, a fire extinguishing system, with an alarm valve with an extinguishing fluid inlet and an extinguishing fluid outlet, the alarm valve having a closing body which can be moved back and forth between a locked state and a released state, the fluid inlet chamber and the fluid outlet chamber being separated from one another in the locked state and communicate fluidly with one another in the release state, an alarm triggering device for triggering a fire alarm, which is connected to the alarm valve, and a delay tank for delaying the triggering of the fire alarm, the alarm valve being fluidly connected to a fluid inlet of the delay tank and a fluid outlet of the delay tank with the Alarm triggering device is connected. The invention further relates to a fire extinguishing system with such an alarm valve station.
Alarmventilstationen von Feuerlöschanlagen dienen zum Auslösen eines Brandalarms. Hierzu ermitteln bekannte Alarmventilstationen regelmäßig den Fluidfluss des Löschfluids zwischen dem Löschfluideinlass, welcher üblicherweise fluidleitend mit einer Löschfluidversorgung verbunden ist, und dem Löschfluidauslass, welcher üblicherweise über ein Fluidleitungssystem fluidleitend mit einer Sprinkleranordnung verbunden ist.Alarm valve stations of fire extinguishing systems are used to trigger a fire alarm. For this purpose, known alarm valve stations regularly determine the fluid flow of the extinguishing fluid between the extinguishing fluid inlet, which is usually fluidly connected to an extinguishing fluid supply, and the extinguishing fluid outlet, which is usually fluidly connected to a sprinkler arrangement via a fluid line system.
Im Brandfall öffnen sich die Sprinklerdüsen der Sprinkleranordnung, sodass das Druckniveau im Leitungssystem der Sprinkleranordnung und somit auch am Löschfluidauslass des Alarmventils abfällt. Der Druckabfall führt zu einer Ausbildung eines Druckunterschieds zwischen dem Löschfluideinlass und dem Löschfluidauslass des Alarmventils. Bei Erreichen eines bestimmten Druckunterschieds wird der im Alarmventil angeordnete und im Ruhezustand des Alarmventils geschlossene Schließkörper geöffnet..In the event of a fire, the sprinkler nozzles of the sprinkler arrangement open so that the pressure level in the line system of the sprinkler arrangement and thus also at the extinguishing fluid outlet of the alarm valve drops. The pressure drop leads to the formation of a pressure difference between the extinguishing fluid inlet and the extinguishing fluid outlet of the alarm valve. When a certain pressure difference is reached, the closing body arranged in the alarm valve and closed when the alarm valve is in the idle state is opened.
Gleichzeitig mit der Öffnung des Schließkörpers zwischen dem Löschfluideinlass und dem Löschfluidauslass wird der Löschfluidzufluss aus dem Inneren des Alarmventils freigegeben, beispielsweise in eine Stichleitung, welche üblicherweise als Alarmleitung bezeichnet wird. Die Stichleitung ist in Ruhestellung des Schließkörpers (nahezu) fluidfrei und drucklos. Ferner ist die Stichleitung fluidleitend mit einem Drucksensor verbunden, welcher die durch das einströmende Löschfluid hervorgerufene Druckänderung in der Stichleitung detektiert. Der Drucksensor ist Teil einer Alarmauslöseeinrichtung. Die Löschfluidversorgung unterliegt, beispielsweise aufgrund von Wasserschlägen im Versorgungsnetz, temporär auftretenden Druckschwankungen. Diese Druckschwankungen können dazu führen, dass die Stichleitung, welche fluidleitend mit dem Drucksensor verbunden ist, kurzzeitig mit Löschfluid druckbeaufschlagt wird. Damit Druckschwankungen der Löschfluidversorgung nicht zu einem Auslösen eines Brandalarm führen, ist dem Drucksensor regelmäßig ein hydraulischer Verzögerungsbehälter vorgeschaltet. Durch den Verzögerungsbehälter baut sich am Drucksensor erst dann ein Druck auf, der als Ereignis für die Erzeugung eines Alarmsignals gewertet wird, wenn eine ausreichend große Menge Löschfluid in die Alarmleitung bzw. den Verzögerungsbehälter einströmt und sich ein entsprechender Druck am Drucksensor aufbaut.. Somit wird verhindert, dass temporär auftretende Druckschwankungen in der Löschfluidversorgung zu einem unbeabsichtigten Auslösen eines Brandalarms führen.Simultaneously with the opening of the closing body between the extinguishing fluid inlet and the extinguishing fluid outlet, the extinguishing fluid inflow is released from the inside of the alarm valve, for example into a spur line, which is usually referred to as an alarm line. The stub is (almost) fluid-free in the rest position of the closing body and depressurized. Furthermore, the spur line is fluidly connected to a pressure sensor which detects the pressure change in the spur line caused by the inflowing extinguishing fluid. The pressure sensor is part of an alarm triggering device. The extinguishing fluid supply is subject to temporary pressure fluctuations, for example due to water hammer in the supply network. These pressure fluctuations can cause the stub line, which is connected to the pressure sensor in a fluid-conducting manner, to be briefly pressurized with extinguishing fluid. To ensure that pressure fluctuations in the extinguishing fluid supply do not trigger a fire alarm, the pressure sensor is regularly preceded by a hydraulic delay tank. The delay tank only builds up pressure at the pressure sensor, which is evaluated as an event for the generation of an alarm signal when a sufficiently large amount of extinguishing fluid flows into the alarm line or the delay tank and a corresponding pressure builds up at the pressure sensor prevents temporary pressure fluctuations in the extinguishing fluid supply from triggering a fire alarm unintentionally.
Der Fluidauslass bekannter Verzögerungsbehälter ist bei einigen, wie in
Die der Erfindung zugrunde liegende Aufgabe ist es eine Möglichkeit zu schaffen, den Verzögerungsbehälter einer Alarmventilstation (auslassseitig) fluidleitend mit mehreren separaten Komponenten zu verbinden, wobei der Montage- und Wartungsaufwand und/oder das Risiko einer Leckage im Vergleich zu den bekannten Lösungen verringert ist und den Verzögerungsbehälters innerhalb der Alarmventilstation platzsparend anzuordnen.The object underlying the invention is to provide a way to fluidly connect the delay tank of an alarm valve station (outlet side) with several separate components, the assembly and maintenance effort and / or the risk of leakage being reduced in comparison to the known solutions and to arrange the delay container within the alarm valve station to save space.
Die Aufgabe wird gelöst mit einer Alarmventilstation der eingangs genannten Art, wobei der Verzögerungsbehälter mehrere Fluideinlässe und/oder mehrere Fluidauslässe aufweist.The object is achieved with an alarm valve station of the type mentioned at the outset, the delay container having a plurality of fluid inlets and / or a plurality of fluid outlets.
Die Erfindung macht sich die Erkenntnis zunutze, dass die Aufteilung des Fluidflusses bzw. -druckes nicht zwangsläufig außerhalb des Verzögerungsbehälters durch eine geeignete Leitungsanordnung erfolgen muss. Durch die Aufteilung des Fluidflusses durch den Verzögerungsbehälter kann auf eine nachgeschaltete Leitungsanordnung zur Aufteilung des Fluidflusses verzichtet werden. Somit wird der Montage- und Wartungsaufwand sowie das Risiko einer Leckage, sowie insbesondere der Platzbedarf erheblich reduziert.The invention makes use of the knowledge that the distribution of the fluid flow or pressure does not necessarily have to take place outside the delay container by means of a suitable line arrangement. By dividing the fluid flow through the delay tank, a downstream line arrangement for dividing the fluid flow can be dispensed with. Thus, the assembly and maintenance effort as well as the risk of leakage and in particular the space requirement is considerably reduced.
Vorzugsweise ist der Löschfluideinlass des Alarmventils dazu eingerichtet, fluidleitend mit einer Löschfluidversorgung verbunden zu werden. Alternativ oder zusätzlich ist der Löschfluidauslass des Alarmventils dazu eingerichtet, fluidleitend mit einer Sprinkleranordnung verbunden zu werden. Außerdem ist ein Verzögerungsbehälter bevorzugt, welcher zwei, drei oder vier Fluideinlässe und/oder zwei, drei oder vier Fluidauslässe aufweist.The extinguishing fluid inlet of the alarm valve is preferably set up to be connected in a fluid-conducting manner to an extinguishing fluid supply. Alternatively or additionally, the extinguishing fluid outlet of the alarm valve is set up to be connected in a fluid-conducting manner to a sprinkler arrangement. In addition, a delay tank is preferred which has two, three or four fluid inlets and / or two, three or four fluid outlets.
Die erfindungsgemäße Alarmventilstation wird dadurch vorteilhaft weitergebildet, dass ein Fluidauslass oder mehrere oder sämtliche der mehreren Fluidauslässe des Verzögerungsbehälters jeweils mit einer oder mehreren Alarmauslöseeinrichtungen verbunden sind. Unter der Alarmauslöseeinrichtung wird erfindungsgemäß jene funktionale Einheit verstanden, die die Erfassung eines Ereignisses umfasst, welches das Erzeugen des Alarmsignals erfordert, etwa den ausreichenden Anstieg des Drucks im Verzögerungsbehälter, sowie die Mittel zur Erzeugung des Alarmsignals. Vorzugsweise umfasst zumindest eine Alarmauslöseeinrichtung einen Drucksensor, welcher dazu eingerichtet ist, eine Druckänderung zu detektieren und in ein elektrisches Signal zu wandeln. Vorzugsweise ist der Drucksensor als Druckschalter ausgebildet.The alarm valve station according to the invention is advantageously further developed in that a fluid outlet or a plurality or all or all of the plurality of fluid outlets of the delay container are each connected to one or more alarm triggering devices. According to the invention, the alarm triggering device is understood to mean that functional unit which comprises the detection of an event which requires the generation of the alarm signal, for example the sufficient increase in the pressure in the delay tank, and the means for generating the alarm signal. At least one alarm triggering device preferably comprises a pressure sensor, which is set up to detect a pressure change and convert it into an electrical signal. The pressure sensor is preferably designed as a pressure switch.
Der Drucksensor ist vorzugsweise signalleitend mit einer Brandmelder- und/oder Löschsteuerzentrale verbunden. Die Brandmelder- und Löschsteuerzentrale verarbeitet vorzugsweise das von dem Drucksensor empfangene Signal, um Alarmeinrichtungen, wie etwa eine oder mehrere elektrisch betriebene Alarmhupen oder eine oder mehrere hydraulisch betriebene Alarmglocken zu steuern und/oder um Alarmmeldungen an ständig besetzte Stellen und die Feuerwehr zu senden. Die Brandmelder- und/oder Löschsteuerzentrale überwacht vorzugsweise kontinuierlich die Feuerlöschanlage, in welcher die erfindungsgemäße Alarmventilstation zum Einsatz kommt. Insbesondere kommuniziert die Brandmelder- und/oder Löschsteuerzentrale mit Gefahrenmanagementsystemen oder über Webinterfaces mit internetfähigen Geräten.The pressure sensor is preferably connected in a signal-conducting manner to a fire alarm and / or extinguishing control center. The fire alarm and extinguishing control center preferably processes the signal received by the pressure sensor in order to control alarm devices, such as one or more electrically operated alarm horns or one or more hydraulically operated alarm bells, and / or to send alarm messages to permanently manned locations and the fire brigade. The fire alarm and / or extinguishing control center preferably continuously monitors the fire extinguishing system in which the alarm valve station according to the invention is used. In particular the fire alarm and / or extinguishing control center communicates with hazard management systems or via web interfaces with internet-enabled devices.
Alternativ oder zusätzlich ist der Drucksensor in einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Alarmventilstation signalleitend mit einer elektrisch betriebenen Alarmeinrichtung verbunden. Die elektrisch betriebene Alarmeinrichtung umfasst vorzugsweise eine Alarmhupe.Alternatively or additionally, in a further preferred embodiment of the alarm valve station according to the invention, the pressure sensor is connected in a signal-conducting manner to an electrically operated alarm device. The electrically operated alarm device preferably comprises an alarm horn.
In einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Alarmventilstation umfasst zumindest eine Alarmauslöseeinrichtung eine hydraulisch betriebene Alarmeinrichtung. Die hydraulisch betriebene Alarmeinrichtung umfasst vorzugsweise eine hydraulische Alarmglocke. Die Alarmglocke dient der Alarmierung der unmittelbaren Umgebung.In a further preferred embodiment of the alarm valve station according to the invention, at least one alarm triggering device comprises a hydraulically operated alarm device. The hydraulically operated alarm device preferably comprises a hydraulic alarm bell. The alarm bell is used to alert the immediate surroundings.
In einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Alarmventilstation sind auf einer ersten Seite des Verzögerungsbehälters mehrere Fluidauslässe angeordnet und auf einer zweiten gegenüberliegenden Seite des Verzögerungsbehälters ist zumindest ein Fluideinlass angeordnet. Dadurch, dass auf der ersten Seite des Verzögerungsbehälters mehrere Fluidauslässe angeordnet sind und auf der zweiten gegenüberliegenden Seite des Verzögerungsbehälters zumindest ein Fluideinlass angeordnet ist, ist das Löschfluid durch den zumindest einen Fluideinlass auf der zweiten Seite des Verzögerungsbehälters in den Verzögerungsbehälter einleitbar. Nachdem der Verzögerungsbehälter vollständig oder im Wesentlichen vollständig mit Löschfluid befüllt ist, fließt Löschfluid durch die mehreren Fluidauslässe auf der ersten Seite des Verzögerungsbehälters aus dem Verzögerungsbehälter bzw. pflanzt sich der durch das in den Verzögerungsbehälter einströmende Fluid aufbauende Druck zu den Fluidauslässen fort.. Durch die gegenüberliegende Anordnung des zumindest einen Fluideinlasses und der mehreren Fluidauslässe kommt es somit zu einer Ausnutzung des gesamten oder im Wesentlichen gesamten Volumens des Verzögerungsbehälters, wodurch eine maximale Verzögerung erreicht wird. Auf der zweiten Seite des Verzögerungsbehälters ist vorzugsweise zusätzlich zu dem Fluideinlass ein Fluidauslass angeordnet. Durch den zusätzlichen Fluidauslass auf der zweiten Seite des Verzögerungsbehälters ist der Verzögerungsbehälter beispielsweise entleerbar. Die Entleerung des Verzögerungsbehälters erfolgt vorzugsweise kontinuierlich, jedoch mit einer geringen Entleerungsrate. Auf diese Weise wird sichergestellt, dass nach einer vollständigen oder teilweisen Befüllung des Verzögerungsbehälters ein Entleerungsprozess stattfindet, sodass das gesamte Volumen des Verzögerungsbehälters bei der darauffolgenden Befüllung zur Verzögerung des hydraulischen Signals zur Verfügung steht. Es ist ferner bevorzugt den Verzögerungsbehälter derart auszurichten, dass die zweite Seite des Verzögerungsbehälters und somit der zumindest eine Fluideinlass und der zusätzliche Fluidauslass unterhalb des Innenraums des Verzögerungsbehälters angeordnet sind, sodass eine Entleerung durch den zusätzlichen Fluidauslass auf der zweiten Seite des Verzögerungsbehälters durch Ausnutzung der Schwerkraft und ohne den Einsatz einer Fluidfördereinrichtung erfolgen kann.In a particularly preferred embodiment of the alarm valve station according to the invention, a plurality of fluid outlets are arranged on a first side of the delay container and at least one fluid inlet is arranged on a second opposite side of the delay container. Because several fluid outlets are arranged on the first side of the delay container and at least one fluid inlet is arranged on the second opposite side of the delay container, the extinguishing fluid can be introduced into the delay container through the at least one fluid inlet on the second side of the delay container. After the delay tank is completely or substantially completely filled with extinguishing fluid, extinguishing fluid flows through the plurality of fluid outlets on the first side of the delay tank out of the delay tank or the pressure building up through the fluid flowing into the delay tank propagates to the fluid outlets Opposing arrangement of the at least one fluid inlet and the plurality of fluid outlets thus results in utilization of the entire or essentially the entire volume of the delay container, as a result of which a maximum delay is achieved. A fluid outlet is preferably arranged on the second side of the delay container in addition to the fluid inlet. The delay container can be emptied, for example, by the additional fluid outlet on the second side of the delay container. The delay container is preferably emptied continuously, but at a low emptying rate. This ensures that an emptying process takes place after the delay container has been completely or partially filled, so that the entire volume of the delay container is available for delaying the hydraulic signal during the subsequent filling stands. It is further preferred to align the delay container in such a way that the second side of the delay container and thus the at least one fluid inlet and the additional fluid outlet are arranged below the interior of the delay container, so that emptying through the additional fluid outlet on the second side of the delay container by utilizing gravity and can be done without the use of a fluid delivery device.
In einer bevorzugten Weiterbildung der erfindungsgemäßen Alarmventilstation ist der zumindest eine Fluideinlass auf der zweiten Seite des Verzögerungsbehälters zu keinem der mehreren Fluidauslässe auf der ersten Seite des Verzögerungsbehälters fluchtend ausgerichtet. Das durch den zumindest einen Fluideinlass in den Verzögerungsbehälter einströmende Löschfluid weist regelmäßig ein Druckniveau auf, welches insbesondere bei anfänglicher Befüllung des Verzögerungsbehälters zur Ausbildung eines Löschfluidstrahls führt. Bei fluchtender Ausrichtung des zumindest einen Fluideinlasses zu einem der mehreren Fluidauslässe besteht das Risiko, dass trotz der Tatsache, dass der Verzögerungsbehälter noch nicht vollständig oder im Wesentlichen vollständig mit Löschfluid befüllt ist, durch den Löschfluidstrahl bereits Löschfluid durch den fluchtend zu dem Fluideinlass ausgerichteten Fluidauslass herausströmt und der Drucksensor ohne Verzögerung oder mit einer zu geringen Verzögerung ein Alarmsignal erzeugt.In a preferred development of the alarm valve station according to the invention, the at least one fluid inlet on the second side of the delay container is not aligned with any of the several fluid outlets on the first side of the delay container. The extinguishing fluid flowing into the delay container through the at least one fluid inlet regularly has a pressure level which leads to the formation of an extinguishing fluid jet, in particular when the delay container is initially filled. If the at least one fluid inlet is aligned with one of the plurality of fluid outlets, there is a risk that, despite the fact that the delay container is not yet completely or substantially completely filled with extinguishing fluid, extinguishing fluid will already flow out through the fluid outlet aligned with the fluid inlet through the extinguishing fluid jet and the pressure sensor generates an alarm signal without delay or with too little delay.
In einer vorteilhaften Ausführungsform der erfindungsgemäßen Alarmventilstation weist der Verzögerungsbehälter eine Längsachse auf, welche sich von der ersten Seite zu der zweiten Seite des Verzögerungsbehälters erstreckt. Ein Fluideinlass oder mehrere oder sämtliche Fluideinlässe sind beabstandet von der Längsachse angeordnet. Alternativ oder zusätzlich ist ein Fluidauslass oder sind mehrere oder sämtliche Fluidauslässe des Verzögerungsbehälters beabstandet von der Längsachse angeordnet. Der Verzögerungsbehälter ist vorzugsweise zumindest abschnittsweise rotationssymmetrisch um eine Mittenachse ausgebildet, wobei die Längsachse der Mittenachse entspricht. Durch die Beabstandung von der Längsachse ist der jeweilige Fluideinlass oder der jeweilige Fluidauslass seitlich am Verzögerungsbehälter angeordnet. Jeder Fluideinlass und Fluidauslass ist mittels eines geeigneten Kopplungsmittels, beispielsweise eines Rohrleitungsfittings, fluidleitend mit einem Rohrleitungsabschnitt oder einer anderen Komponente fluidleitend verbindbar. Die seitliche Anordnung der jeweiligen Fluideinlässe und der jeweiligen Fluidauslässe erlaubt trotz einer Mehrzahl von Fluideinlässen und/oder Fluidauslässen diese Kopplung. Insgesamt kann der Verzögerungsbehälter hierdurch auf platzsparende Art und Weise in die Alarmventilstation integriert werden.In an advantageous embodiment of the alarm valve station according to the invention, the delay container has a longitudinal axis which extends from the first side to the second side of the delay container. One or more or all of the fluid inlets are spaced apart from the longitudinal axis. Alternatively or additionally, there is a fluid outlet or several or all of the fluid outlets of the delay container are arranged at a distance from the longitudinal axis. The delay container is preferably at least sectionally rotationally symmetrical about a central axis, the longitudinal axis corresponding to the central axis. Due to the spacing from the longitudinal axis, the respective fluid inlet or the respective fluid outlet is arranged on the side of the delay tank. Each fluid inlet and fluid outlet can be fluidly connected to a pipeline section or another component by means of a suitable coupling means, for example a pipeline fitting. The lateral arrangement of the respective fluid inlets and the respective fluid outlets permits this coupling despite a plurality of fluid inlets and / or fluid outlets. Overall, the delay container can hereby be integrated into the alarm valve station in a space-saving manner.
Die erfindungsgemäße Alarmventilstation wird dadurch vorteilhaft weitergebildet, dass der Verzögerungsbehälter mehrteilig ausgebildet ist. Durch die mehrteilige Ausbildung des Verzögerungsbehälters wird einerseits die Herstellung des Verzögerungsbehälters vereinfacht und andererseits die Anpassbarkeit des Verzögerungsbehälters gesteigert. Ferner ist die Montage und Wartung des Verzögerungsbehälters vereinfacht.The alarm valve station according to the invention is advantageously further developed in that the delay container is constructed in several parts. The multi-part design of the delay container on the one hand simplifies the manufacture of the delay container and on the other hand increases the adaptability of the delay container. Furthermore, the assembly and maintenance of the delay container is simplified.
In einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Alarmventilstation weist der Verzögerungsbehälter ein erstes Behälterteil und ein von dem ersten Behälterteil lösbares, vorzugsweise reversibel und zerstörungsfrei lösbares, zweites Behälterteil auf. Durch die zwei separaten und voneinander lösbaren Behälterteile wird die Universalität des Verzögerungsbehälters weiter gesteigert.In a particularly preferred embodiment of the alarm valve station according to the invention, the delay container has a first container part and a second container part that is detachable, preferably reversible and non-destructively detachable from the first container part. The universality of the delay container is further increased by the two separate and detachable container parts.
Ferner ist eine erfindungsgemäße Alarmventilstation bevorzugt, bei welcher das erste Behälterteil und das zweite Behälterteil jeweils einen Flanschabschnitt aufweisen, wobei die Flanschabschnitte des ersten Behälterteils und des zweiten Behälterteils zum gegenseitigen Verbinden ausgebildet sind. Vorzugsweise ist der jeweilige Flanschabschnitt einstückig mit dem jeweiligen Behälterteil ausgebildet. Es ist ferner bevorzugt, dass der Flanschabschnitt des ersten Behälterteils und der Flanschabschnitt des zweiten Behälterteils als umlaufender Flanschabschnitt ausgebildet sind. Vorzugsweise erstreckt sich der Flanschabschnitt des ersten Behälterteils und der Flanschabschnitt des zweiten Behälterteils von dem Innenraum des jeweiligen Behälterteils radial nach außen.Furthermore, an alarm valve station according to the invention is preferred, in which the first container part and the second container part each have a flange section, the flange sections of the first container part and the second container part being designed for mutual connection. The respective flange section is preferably formed in one piece with the respective container part. It is further preferred that the flange section of the first container part and the flange section of the second container part are designed as a circumferential flange section. The flange section of the first container part and the flange section of the second container part preferably extend radially outward from the interior of the respective container part.
In einer weiteren bevorzugten Ausführungsform der erfindungsgemäßen Alarmventilstation sind das erste Behälterteil und das zweite Behälterteil identisch. Auf diese Weise kommt es zu einer erheblichen Reduzierung der Herstellungskosten, beispielsweise der Modellkosten für die Fertigung von Gussteilen. Insbesondere weist das erste Behälterteil des Verzögerungsbehälters mehrere, vorzugsweise zwei Fluidauslässe auf. Insbesondere weist das zweite Behälterteil des Verzögerungsbehälters zumindest einen Fluideinlass auf. Das zweite Behälterteil des Verzögerungsbehälters weist darüber hinaus vorzugsweise zusätzlich zu dem Fluideinlass einen Fluidauslass auf.In a further preferred embodiment of the alarm valve station according to the invention, the first container part and the second container part are identical. In this way, there is a considerable reduction in the manufacturing costs, for example the model costs for the production of castings. In particular, the first container part of the delay container has several, preferably two, fluid outlets. In particular, the second container part of the delay container has at least one fluid inlet. The second container part of the delay container also preferably has a fluid outlet in addition to the fluid inlet.
Die erfindungsgemäße Alarmventilstation wird ferner dadurch vorteilhaft weitergebildet, dass das erste Behälterteil und das zweite Behälterteil in verschiedenen Drehwinkelstellungen miteinander verbindbar sind. Dadurch, dass das erste Behälterteil und das zweite Behälterteil in verschiedenen Drehwinkelstellungen miteinander verbindbar sind, kann die Position der Fluidauslässe und des zumindest einen Fluideinlasses des Verzögerungsbehälters verändert werden. Beispielsweise sind das erste Behälterteil und das zweite Behälterteil in insgesamt 4 verschiedenen Drehwinkelstellungen miteinander verbindbar, wobei
- in einer ersten Drehwinkelstellung das erste Behälterteil und das zweite Behälterteil keine Verdrehung aufweisen, also die Anschlüsse fluchtend angeordnet sind,
- in einer zweiten Drehwinkelstellung das erste Behälterteil und das zweite Behälterteil zueinander insgesamt um 90 Grad um eine Mittenachse des Verzögerungsbehälters verdreht sind,
- in einer dritten Drehwinkelstellung das erste Behälterteil und das zweite Behälterteil zueinander insgesamt um 180 Grad um die Mittenachse des Verzögerungsbehälters verdreht sind und
- in einer vierten Drehwinkelstellung das erste Behälterteil und das zweite Behälterteil zueinander insgesamt um 270 Grad um die Mittenachse des Verzögerungsbehälters verdreht sind.
- in a first angle of rotation position, the first container part and the second container part have no rotation, that is to say the connections are arranged in alignment,
- in a second angle of rotation position, the first container part and the second container part are rotated by a total of 90 degrees relative to one another about a central axis of the delay container,
- in a third angle of rotation position, the first container part and the second container part are rotated relative to one another by a total of 180 degrees around the central axis of the delay container and
- in a fourth angle of rotation position, the first container part and the second container part are rotated with respect to one another by a total of 270 degrees about the central axis of the delay container.
Ferner sind ebenfalls Verzögerungsbehälter bevorzugt, deren erstes Behälterteil und deren zweites Behälterteil in insgesamt zwei, drei, vier, fünf, sechs, sieben, acht, neun oder zehn verschiedenen Drehwinkelstellungen miteinander verbindbar sind. Vorzugsweise umfasst das erste Behälterteil eine Anzahl von Bohrungen am Flanschabschnitt und das zweite Behälterteil eine identische Anzahl von Bohrungen, wobei die Anzahl der Bohrungen in den jeweiligen Behälterteilen der Anzahl der möglichen Drehwinkelstellungen entspricht. Vorzugsweise umfassen das erste Behälterteil und das zweite Behälterteil jeweils insgesamt zwei, drei, vier, fünf, sechs, sieben, acht, neun oder zehn Bohrungen.Delay containers are also preferred, the first container part and the second container part of which can be connected to one another in a total of two, three, four, five, six, seven, eight, nine or ten different rotational angle positions. The first container part preferably comprises a number of bores on the flange section and the second container part an identical number of bores, the number of bores in the respective container parts corresponding to the number of possible angular positions. The first container part and the second container part preferably each comprise a total of two, three, four, five, six, seven, eight, nine or ten bores.
In einer bevorzugten Ausführungsform der erfindungsgemäßen Alarmventilstation ist zwischen dem ersten Behälterteil und dem zweiten Behälterteil ein Dichtungselement angeordnet, welches in den Innenraum des Verzögerungsbehälters hineinragt.In a preferred embodiment of the alarm valve station according to the invention, a sealing element is arranged between the first container part and the second container part, which protrudes into the interior of the delay container.
In einer vorteilhaften Ausführungsform der erfindungsgemäßen Alarmventilstation weisen der Fluideinlass oder die Fluideinlässe des Verzögerungsbehälters jeweils eine Mittelachse auf, wobei das Dichtungselement derart in den Innenraum des Verzögerungsbehälters hineinragt, dass die Mittelachse des einen Fluideinlasses oder der mehreren Fluideinlässe das Dichtungselement schneidet bzw. schneiden. Das Dichtungselement dient somit als Prallelement für in den Verzögerungsbehälter eintretendes Löschfluid. Das Dichtungselement umfasst vorzugsweise eine elastische Dichtlippe, welche vorzugsweise sich in den Innenraum des Verzögerungsbehälters erstreckt.In an advantageous embodiment of the alarm valve station according to the invention, the fluid inlet or the fluid inlets of the delay container each have a central axis, the sealing element protruding into the interior of the delay container such that the central axis of the one fluid inlet or the plurality of fluid inlets intersects or intersects the sealing element. The sealing element thus serves as an impact element for extinguishing fluid entering the delay container. The sealing element preferably comprises an elastic one Sealing lip, which preferably extends into the interior of the delay container.
Bevorzugt ist auch eine erfindungsgemäße Alarmventilstation, bei welcher der Fluideinlass oder die Fluideinlässe des Verzögerungsbehälters zu einem oder zu mehreren Fluidauslässen des Verzögerungsbehälters fluchtend ausgerichtet ist/sind. Die fluchtende Anordnung des Fluideinlasses oder der Fluideinlässe des Verzögerungsbehälters zu einem oder zu mehreren Fluidauslässen des Verzögerungsbehälters ist insbesondere dann bevorzugt, wenn der Verzögerungsbehälter ein als Prallelement wirkendes Dichtungselement aufweist. Durch das Prallelement wird verhindert, dass auch bei fluchtender Ausrichtung des Fluideinlasses oder der Fluideinlässe des Verzögerungsbehälters zu einem oder zu mehreren Fluidauslässen des Verzögerungsbehälters, kein Risiko besteht, dass sich innerhalb des Verzögerungsbehälters ein Löschfluidstrahl zwischen einem Fluideinlass und einem Fluidauslass ausbildet und der Drucksensor ohne Verzögerung oder mit einer zu geringen Verzögerung ein elektrisches Signal erzeugt.Also preferred is an alarm valve station according to the invention, in which the fluid inlet or the fluid inlets of the delay container is / are aligned with one or more fluid outlets of the delay container. The alignment of the fluid inlet or the fluid inlets of the delay container with one or more fluid outlets of the delay container is particularly preferred when the delay container has a sealing element which acts as a baffle element. The impact element prevents that, even when the fluid inlet or the fluid inlets of the delay container are aligned with one or more fluid outlets of the delay container, there is no risk that an extinguishing fluid jet will form between a fluid inlet and a fluid outlet and the pressure sensor without delay or generates an electrical signal with too little delay.
In einer vorteilhaften Weiterbildung der erfindungsgemäßen Alarmventilstation ist ein Fluidauslass des Verzögerungsbehälters fluidleitend mit einer Entleerungseinrichtung verbunden, welche dazu eingerichtet ist, den Verzögerungsbehälter selbsttätig zu entleeren. Alternativ oder zusätzlich dient ein Fluideinlass des Verzögerungsbehälters temporär ebenfalls als Fluidauslass. Vorzugsweise sind auf einer ersten Seite des Verzögerungsbehälters mehrere, insbesondere zwei Fluidauslässe und auf einer gegenüberliegenden zweiten Seite des Verzögerungsbehälters sind ein Fluideinlass und ein fluidleitend mit der Entleerungseinrichtung verbundener Fluidauslass angeordnet. Insbesondere weist das erste Behälterteil des Verzögerungsbehälters mehrere, vorzugsweise zwei Fluidauslässe auf und das zweite Behälterteil des Verzögerungsbehälters weist einen Fluideinlass und einen fluidleitend mit der Entleerungseinrichtung verbundenen Fluidauslass auf. Zwischen dem Alarmventil und dem Verzögerungsbehälter bzw. zwischen Alarmventil und Alarmeinrichtung ist bzw. sind vorzugsweise ein Schmutzfänger, ein oder mehrere Drosseln und/oder Absperrventile angeordnet.In an advantageous development of the alarm valve station according to the invention, a fluid outlet of the delay container is connected in a fluid-conducting manner to an emptying device which is set up to empty the delay container automatically. Alternatively or additionally, a fluid inlet of the delay container also temporarily serves as a fluid outlet. A plurality of, in particular two, fluid outlets are preferably arranged on a first side of the delay container and a fluid inlet and a fluid outlet connected to the emptying device in a fluid-conducting manner are arranged on an opposite second side of the delay container. In particular, the first container part of the delay container has a plurality of, preferably two, fluid outlets and the second container part of the delay container has a fluid inlet and a fluid outlet that is connected in a fluid-conducting manner to the emptying device. A dirt trap, one or more throttles and / or shut-off valves are or are preferably arranged between the alarm valve and the delay container or between the alarm valve and the alarm device.
Vorzugsweise verhindert ein Rückschlagventil, dass im Bereitschaftszustand der Feuerlöschanlage, d.h. wenn kein Sprinkler der Feuerlöschanlage geöffnet ist, bei sinkendem Druck der Löschfluidversorgung auch der Druck im Rohrnetz der Sprinkleranordnung absinkt. Somit wird auch bei sinkendem Löschfluidversorgungsdruck die Funktionsbereitschaft der Feuerlöschanlage aufrecht erhalten. Das Rückschlagventil verringert außerdem das Risiko, dass bei wieder ansteigendem Löschfluidversorgungsdruck Wasser in das Rohrnetz der Sprinkleranordnung strömt und hierdurch unbeabsichtigt einen Alarm auslöst.A non-return valve preferably prevents the fire extinguishing system from being ready, ie if no sprinkler of the fire extinguishing system is open, and the pressure in the pipe network of the sprinkler arrangement also drops as the pressure of the extinguishing fluid supply falls. Thus, the operational readiness of the fire extinguishing system is maintained even when the extinguishing fluid supply pressure drops. The check valve also reduces the risk that if the extinguishing fluid supply pressure rises again Water flows into the pipe network of the sprinkler arrangement and thereby unintentionally triggers an alarm.
Vorzugsweise ist der Verzögerungsbehälter aus Kunststoff oder aus Edelstahl ausgebildet.The delay container is preferably made of plastic or stainless steel.
Die der Erfindung zugrunde liegende Aufgabe wird außerdem gelöst mit einer Feuerlöschanlage, mit einer Alarmventilstation, einer Löschfluidversorgung und einer Sprinkleranordnung. Die Alarmventilstation der erfindungsgemäßen Feuerlöschanlage ist gemäß einer der vorstehend beschriebenen Ausführungsformen ausgebildet. Die Löschfluidversorgung ist fluidleitend mit dem Löschfluideinlass des Alarmventils verbunden. Die Sprinkleranordnung ist fluidleitend mit dem Löschfluidauslass des Alarmventils verbunden. Hinsichtlich der Vorteile der erfindungsgemäßen Feuerlöschanlage wird auf die Vorteile der erfindungsgemäßen Alarmventilstation verwiesen.The object underlying the invention is also achieved with a fire extinguishing system, with an alarm valve station, an extinguishing fluid supply and a sprinkler arrangement. The alarm valve station of the fire extinguishing system according to the invention is designed in accordance with one of the embodiments described above. The extinguishing fluid supply is fluidly connected to the extinguishing fluid inlet of the alarm valve. The sprinkler arrangement is fluidly connected to the extinguishing fluid outlet of the alarm valve. With regard to the advantages of the fire extinguishing system according to the invention, reference is made to the advantages of the alarm valve station according to the invention.
