Abstract

Gas high-pressure fire-extinguishing equipment (1) comprises a gaseous extinguishing agent stored under high pressure in at least one gas bottle (2-4) provided with a quick-opening valve (5-7) connected to a collecting pipe (11) from which one or more range valves (15-17) with operating-pressure-reducing devices (18-20) lead to fire-extinguishing lines (21-23) with fire-extinguishing nozzles (24). A further pressure-reducing device (25, 28) is arranged between at least one quick-opening valve and the operating-pressure-reducing devices.

Description

Die Neuerung betrifft eine Gas-Hochdruck-Feuerlöschanlage, bei der das gasförmige Löschmittel unter hohem Druck in einer oder mehreren Gasflaschen gelagert ist, die jeweils mit einem Schnellöffnungsventil versehen sind, an die Anschlußschläuche angeschlossen sind, die zu einem Sammelrohr und einer Druckreduziereinrichtung und von dort bei Einbereichslöschanlagen zu einem oder bei Mehrbereichslöschanlagen zu mehreren Bereichsventilen und von dort über Löschleitungen zu Löschdüsen geführt sind.The innovation concerns a gas high-pressure fire extinguishing system, at of the gaseous extinguishing agent under high pressure in one or several gas cylinders is stored, each with one Quick opening valve are provided on the connecting hoses are connected to a manifold and a pressure reducing device and from there to single-zone extinguishing systems one or, in the case of multi-zone extinguishing systems, to several zone valves and from there via extinguishing lines to extinguishing nozzles are.

Derartige Feuerlöschanlagen werden bisher mit einem mit 200 bar in Hochdruck-Gasflaschen gelagerten Löschmittel betrieben. Die Bevorratung des Löschmittels unter hohem Druck erfolgt aus wirtschaftlichen Gründen. Hochdruck-Gasflaschen für eine Löschanlage benötigen einen geringeren Platzbedarf gegenüber einer Löschanlage mit Niederdruck-Gasflaschen. So ist beispielsweise bei m2-Grundflächenpreisen von DM 6.000,- und mehr in Bürohochhäusern jeder eingesparte m2 ein Gewinn. Beim Einsatz von Hochdruck-Gasflaschen kann die Anzahl der Flaschen, gegenüber den Niederdruck-Gasflaschen, wesentlich verringert werden. Mit weniger Gasflaschen werden die Transport-, Montage- und Wartungskosten erheblich geringer.Such fire extinguishing systems have so far been operated with an extinguishing agent stored at 200 bar in high-pressure gas bottles. The extinguishing agent is stored under high pressure for economic reasons. High-pressure gas bottles for an extinguishing system require less space than an extinguishing system with low-pressure gas bottles. For example, with m 2 floor space prices of DM 6,000 and more in office skyscrapers, every m 2 saved is a profit. When using high-pressure gas bottles, the number of bottles can be significantly reduced compared to low-pressure gas bottles. With fewer gas bottles, the transport, assembly and maintenance costs are significantly lower.

Löschdüsen mit einem gasförmigen Löschmittel mit einem Druck von 200 bar zu beaufschlagen ist unwirtschaftlich und auch gefährlich, wenn das Löschmittel mit dem hohen Druck aus den Löschdüsen austritt. Um diese Nachteile zu vermeiden, wurde das Löschmittel hinter dem Sammlerohr auf einen Druck von 60 bar oder weniger reduziert. Dadurch konnte auch das Rohrnetz und die Löschdüsen wirtschaftlicher hergestellt werden.Extinguishing nozzles with a gaseous extinguishing agent at a pressure to pressurize from 200 bar is uneconomical and also dangerous, if the extinguishing agent with the high pressure from the Extinguishing nozzles emerges. To avoid these disadvantages, the Extinguishing agent behind the collector pipe to a pressure of 60 bar or less reduced. This also enabled the pipe network and the extinguishing nozzles are manufactured more economically.

Weil aus Sicherheitsgründen ein Prüfdruck von 750 bar verlangt wird, verursachen insbesondere die Anlagenteile vom Schnellöffnungsventil bis einschließlich zur Betriebs-druckreduziereinrichtung bei der Herstellung hohe Kosten.Because a safety pressure of 750 bar is required for safety reasons cause especially the system parts of the quick opening valve up to and including the operating pressure reducing device high cost of manufacture.

Der Neuerung liegt die Aufgabe zugrunde, bei einer Gas-Hochdruck-Feuerlöschanlage die Bevorratung des gasförmigen Löschmittels durch den Einsatz von einfachsten Mitteln von 200 bar auf 300 bar umzustellen.The innovation is based on the task of a gas high-pressure fire extinguishing system the storage of the gaseous extinguishing agent by using the simplest means of 200 bar to switch to 300 bar.

Diese Aufgabe wird dadurch gelöst, daß zwischen dem Schnellöffnungsventil und der bisherigen Druckreduziereinrichtung eine vorgeschaltete weitere Druckreduziereinrichtung vorgesehen ist.This object is achieved in that between the quick opening valve and the previous pressure reducing device upstream further pressure reducing device is provided.

Mit dieser Maßnahme wird durch die zusätzliche frühe Druckreduziereinrichtung unmittelbar hinter dem Schnellöffnungsventil der Hochdruck-Massenaustrag aus einer Hochdruck-Gasflasche auf einen Systemdruck niedriger Stufe minimiert. So wird zum Beispiel der Gasdruck in der ersten Stufe von 300 bar auf 200 bar reduziert und das Löschgas tritt mit diesem reduzierten Druck in das Hochdruck-Sammelrohr ein. In der Druckreduziereinrichtung wird in der zweiten Stufe der Gasdruck von 200 bar auf 60 bar oder weniger reduziert. Ab dem Sammelrohr kann die bisherige "200 bar - Technik" ohne Veränderung verwendet werden, jedoch mit der Ausnahme, daß eine zusätzliche Sicherheitseinrichtung für Drücke über 240 bar zu installieren ist. Zu diesem Zweck ist vorzugsweise an dem den Löschdüsen abgewandten Ende des Sammelrohres eine ins Freie geführte Verlängerungsleitung vorgesehen, in die eine Sicherheitseinrichtung, wie eine Berstscheibe oder ein Sicherheitsventil, eingebaut ist. Diese Sicherheitseinrichtung muß ausreichend dimensioniert sein, um sicherzustellen, daß im Störfall der Gasmassenstrom mit Sicherheit ins Freie gelangt. Die sich ergebende Strahlkraft kann noch durch Zerstäubung, Umleitung od.dgl. minimiert werden.With this measure, the additional early pressure reducing device immediately behind the quick opening valve the high pressure mass discharge from a high pressure gas bottle minimizes a low level system pressure. So becomes Example of gas pressure in the first stage from 300 bar to 200 bar reduced and the extinguishing gas occurs with this reduced Pressure into the high pressure manifold. In the pressure reducing device the gas pressure will rise to 200 bar in the second stage Reduced 60 bar or less. From the manifold, the previous one "200 bar technology" can be used without modification, however with the exception that an additional safety device must be installed for pressures above 240 bar. To this The purpose is preferably at the end facing away from the extinguishing nozzles of the collector pipe is an extension line that is led outside provided in which a safety device, such as a rupture disc or a safety valve is installed. This Safety device must be dimensioned sufficiently to ensure that in the event of a malfunction the gas mass flow is certain got outside. The resulting radiance can still by atomization, diversion or the like. be minimized.

Die frühe zusätzliche Druckreduzierung kann unmittelbar hinter dem Schnellöffnungsventil oder unmittelbar vor dem Sammelrohr vorgenommen werden. Diese Druckreduzierung erfolgt durch eine Querschnittsveränderung mittels einer Drosselscheibe mit einer Bohrung von vorzugsweise 10 mm Durchmesser. Diese berechnete Bohrung ist der Löschanlage nach Einsatzzweck angepaßt ausgelegt.The early additional pressure reduction can be immediately behind the quick-opening valve or immediately in front of the manifold be made. This pressure reduction is done by a Cross-sectional change using a throttle disc with a Bore of preferably 10 mm in diameter. This calculated The bore of the extinguishing system is designed according to the application.

Die frühe Druckreduzierung mittels einer der Drosseleinrichtungen hat den weiteren Vorteil, daß bei einer Einbereichs-Feuerlöschanlage auf das Hochdruck-Sammelrohr verzichtet und dafür ein Niederdruck-Sammelrohr eingesetzt werden kann. Denn in diesem Fall erfolgt die Druckreduzierung bereits vor dem Sammelrohr von 200 bar auf 60 bar oder weniger. Für diesen Druck ist ein Hochdruck-Sammelrohr nicht erforderlich. Demzufolge kann das Löschmittel ohne weitere Druckreduzierung direkt zu den Löschdüsen geführt werden.The early pressure reduction using one of the throttling devices has the further advantage that in a single-zone fire extinguishing system dispenses with the high-pressure manifold and a low-pressure manifold can be used for this. Because in this case, the pressure is reduced before Collector tube from 200 bar to 60 bar or less. For this A high pressure manifold is not required for pressure. As a result the extinguishing agent can be used directly without further pressure reduction to the extinguishing nozzles.

Aufgrund der Druckreduzierung unmittelbar hinter dem Schnellöffnungsventil können vorhandene Niederdruck-Feuerlöschanlagen ohne große Umstellung auf Hochdruck-Feuerlöschanlagen umgerüstet werden.Due to the pressure reduction immediately behind the Quick opening valves can use existing low pressure fire extinguishing systems without major changeover to high pressure fire extinguishing systems be converted.

Die Neuerung ist nachfolgend in einem Ausführungsbeispiel für eine Mehrbereits-Feuerlöschanlage mit mehreren Gasflaschen näher erläutert.The innovation is below in an embodiment for a multi-purpose fire extinguishing system with several gas bottles explained in more detail.

Stand der TechnikState of the art

Die bisher bekannten Gas-Hochdruck-Feuerlöschanlagen werden mit einer sogenannten "200 bar - Technik" betrieben. Hierbei sind die Gasflaschen für das Löschmittel mit einem Gasdruck von 200 bar gefüllt. Aus diesem Grund mußten die Schnellöffnungsventile, die Anschlußschläuche, das Sammelrohr und die Verteilerleitungen mit den Bereichsventilen, einschließlich der Druckreduziereinrichtung kostenaufwendig für einen Betriebsdruck von 240 bar und einem Prüfdruck von 750 bar ausgelegt werden. Die Druckreduziereinrichtungen reduzierten den Druck auf <= 60 bar. The previously known gas high-pressure fire extinguishing systems are included a so-called "200 bar technology" operated. Here are the gas bottles for the extinguishing agent with a gas pressure of 200 bar filled. For this reason, the quick opening valves, the connecting hoses, the manifold and the distribution lines with the range valves, including the pressure reducing device costly for an operating pressure of 240 bar and a test pressure of 750 bar. The Pressure reducing devices reduced the pressure to <= 60 bar.

Die "200 bar - Technik" wird neuerungsgemäß beibehalten, obwohl neuerungsgemäß mit einem Flaschendruck von 300 bar gearbeitet wird.The "200 bar technology" is retained according to the innovation, although worked according to the innovation with a bottle pressure of 300 bar becomes.

Mehrbereichs-Feuerlöschanlage nach Figur 1Multi-zone fire extinguishing system according to Figure 1

Die Gasflaschen 2 bis 4 der Mehrbereichs-Anlage 1 mit den Schnellöffnungsventilen 5 bis 7 sind mit einem Gasdruck von 300 bar gefüllt. Entweder sind die Schnellöffnungsventile 5 bis 7 mit Druckreduziereinrichtungen 25 bis 27 oder das Hochdruck-Sammelrohr 11 mit Druckreduziereinrichtungen 28 bis 30 versehen. Nur eine der beiden Druckreduziereinrichtungen, also 25 oder 28 - siehe Figur 2, wird eingebaut. Über Anschlußschläuche 8 bis 10 sind die Schnellöffnungsventile 5-7 mit dem Sammelrohr 11 verbunden. An das Sammelrohr 11 schließen sich Verteilerleitungen 12 bis 14 zu den Mehrbereichs-Ventilen 15 bis 17 mit den Druckreduziereinrichtungen 18 bis 20 und die Löschleitungen 21 bis 23 mit den Löschdüsen 24 an. Am anderen Ende des Sammelrohres 11 ist eine durch das Hallendach 41 in's Freie geführte Verlängerungsleitung 38 angeschlossen, in die eine Scheibenhalterung 40 mit einer Berstscheibe 39 als Sicherheitseinrichtung eingebaut ist.The gas bottles 2 to 4 of the multi-range system 1 with the Quick opening valves 5 to 7 are with a gas pressure of 300 bar filled. Either the quick opening valves are 5 to 7 with pressure reducing devices 25 to 27 or the high pressure manifold 11 provided with pressure reducing devices 28 to 30. Only one of the two pressure reducing devices, i.e. 25 or 28 - see Figure 2, is installed. Via connection hoses 8 to 10 are the quick opening valves 5-7 with the Collector tube 11 connected. Connect to the manifold 11 Distribution lines 12 to 14 to the multi-range valves 15 to 17 with the pressure reducing devices 18 to 20 and the Extinguishing lines 21 to 23 with the extinguishing nozzles 24. At the other The end of the collecting pipe 11 is through the hall roof 41 in Free guided extension line 38 connected into the a disc holder 40 with a rupture disc 39 as a safety device is installed.

Die Schnellöffnungsventile 5 bis 7 werden am Beispiel des Schnellöffnungsventils 5 gemäß Figur 2 beschrieben.The quick opening valves 5 to 7 are based on the example of the Quick opening valve 5 described in Figure 2.

Das Schnellöffnungsventil 5 besteht aus einem Ventilkörper 43, der mittels einer unteren Gewindebohrung 44 auf den Hals 45 der Gasflasche 2 aufgeschraubt ist. Ein Steuerkolben 46 mit einer Kolbenplatte 47 und einer Dichtungsplatte 48 mit Dichtung 49 ist innerhalb des Ventilkörpers 43 eingebaut. Mittels Federn 50 wird die Dichtplatte 48 gegen die Dichtung 49 gedrückt und damit das Schnellöffnungsventil 5 geschlossen gehalten. Eine obere Eintrittsöffnung 51 ist mittels einer Ventilkappe 52 mit Anschlußstutzen 53 für eine Steuerleitung 55 verschlossen. Zwischen der Kolbenplatte 47 und der Dichtplatte 48 ist im Ventilkörper 43 eine Austrittsbohrung 54 für das Löschmittel vorgesehen, die in einen Stutzen 31 übergeht. Innerhalb des Stutzens 31 ist eine Drosselscheibe 33 mit einer Bohrung eingebaut. Mittels eines Verbindungsstückes 35 als Rückflußverhinderer ist der Anschlußschlauch 8 an das Schnellöffnungsventil 5 angeschlossen. Die zuvor beschriebenen Teile 31, 33 und 35 bilden die Drosseleinrichtung 25. Die Drosseleinrichtung 28 ist mit dem Hochdruck-Sammelrohr 11 verbunden und besteht aus dem Stutzen 32 und dem Verbindungsstück 36 für das Anbringen des anderen Ende des Anschlußschlauches 8. In den Stutzen 32 ist eine mit einer Bohrung versehene Drosselscheibe 34 und eine Rückschlagklappe 42 eingebaut.The quick opening valve 5 consists of a valve body 43, which by means of a lower threaded bore 44 on the neck 45 of the Gas bottle 2 is screwed on. A control piston 46 with a Piston plate 47 and a seal plate 48 with seal 49 is installed inside the valve body 43. Using springs 50 the sealing plate 48 is pressed against the seal 49 and thus the quick opening valve 5 kept closed. A upper inlet opening 51 is also by means of a valve cap 52 Connection piece 53 closed for a control line 55. Between the piston plate 47 and the sealing plate 48 is in the valve body 43 an outlet bore 54 is provided for the extinguishing agent, which merges into a nozzle 31. Within the Nozzle 31, a throttle disc 33 is installed with a bore. By means of a connecting piece 35 as a backflow preventer is the connecting hose 8 to the quick opening valve 5 connected. Form the previously described parts 31, 33 and 35 the throttle device 25. The throttle device 28 is connected to the high pressure manifold 11 and consists of the Port 32 and the connector 36 for attaching the other end of the connecting hose 8. In the socket 32 is a throttled disk 34 with a bore and one Check valve 42 installed.

Für die Steuerung der Feuerlöschanlage 1 ist eine Brandmeldezentrale (BMZ) 56 vorgesehen, an die einerseits eine von einem Brandmelder 58 ausgehende Steuerleitung 57 und andererseits eine zu dem Schnellöffnungsventil 5 geführte Steuerleitung 55 angeschlossen sind.A fire alarm control panel is used to control the fire extinguishing system 1 (BMZ) 56 provided, on the one hand one of one Fire detector 58 outgoing control line 57 and on the other hand a control line 55 leading to the quick opening valve 5 are connected.

Das gasförmige Löschmittel ist mit 300 bar in den Gasflaschen 2 bis 4 bevorratet. Die Schnellöffnungsventile 5 sind geschlossen. Im Brandfalle wird über den Brandmelder 58 die BMZ 56 angesteuert und von dort über die Steuerleitung 55 ein Druck auf die Kolbenplatte 47 eines oder mehrerer Schnellöffnungsventile 5-7 ausgeübt. Demzufolge wird die Kolbenplatte 47 nach Überwindung des Federdruckes der Feder 50 nach unten gedrückt und damit das angesteuerte Schnellöffnungsventil 5-7 geöffnet. Jetzt fließt das Löschmittel - jenachdem welche Drosseleinrichtung eingebaut ist - entweder durch die Drosseleinrichtung 25 oder 28, wobei es auf 200 bar reduziert wird, in das Sammelrohr 11 und weiter zu den Druckreduziereinrichtungen 18 -20. Hier wird der Druck des Löschmittels ein zweites Mal auf 60 bar oder weniger reduziert. Mit diesem Druck gelangt das Löschmittel über das Niederdruck-Rohrnetz 21-23 zu den Löschdüsen 24.The gaseous extinguishing agent is at 300 bar in the gas bottles 2 stocked up to 4. The quick opening valves 5 are closed. In the event of a fire, the BMZ 56 is activated via the fire detector 58 and from there on the control line 55 a pressure the piston plate 47 of one or more quick opening valves 5-7 exercised. As a result, the piston plate 47 after overcoming the spring pressure of the spring 50 pressed down and thus the controlled quick opening valve 5-7 opened. Now the extinguishing agent flows - depending on which throttle device is installed - either by the throttle device 25 or 28, whereby it is reduced to 200 bar, into the collecting pipe 11 and on to the pressure reducing devices 18 -20. Here will the pressure of the extinguishing agent a second time to 60 bar or less reduced. With this pressure, the extinguishing agent arrives via the low-pressure pipe network 21-23 to the extinguishing nozzles 24.

Einbereichs-Löschanlage mit mehreren GasflaschenSingle-zone extinguishing system with several gas bottles

Bei einer "300 bar Einbereichs-Löschanlage" entfallen die Verteilerleitungen 13,14 mit den Bereichsventilen 16,17, den Druckreduziereinrichtungen 19,20 und die Löschleitungen 22,23 mit den Löschdüsen 24. In diesem Falle wird das Löschmittel aus dem Hochdruck-Sammelrohr 11 nur über die Verteilerleitung 12 mit dem Bereichsventil 15 und der Druckreduziereinrichtung 18 durch die Löschleitung 21 zu den Löschdüsen 24 geführt.With a "300 bar single-zone extinguishing system", the distribution lines are not required 13,14 with the range valves 16,17, Pressure reducing devices 19, 20 and the extinguishing lines 22, 23 with the extinguishing nozzles 24. In this case the extinguishing agent is out the high-pressure manifold 11 only via the distribution line 12 with the range valve 15 and the pressure reducing device 18 through the extinguishing line 21 to the extinguishing nozzles 24.
