Abstract
Description
Die Erfindung betrifft eine Feuerlösch-Trockensprinkler-Anlage und ein Verfahren zum Betreiben einer Feuerlösch-Trockensprinkler- Anlage. Trockensprinkler-Anlagen sind bekannt. Sie werden vielfach in frostgefährdeten Räumen eingesetzt, um zu vermeiden, dass ein mit Löschwasser gefülltes Sprinklerrohrnetz einfriert. Mittels eines Kompressors wird das Sprinklerrohrnetz vorzugsweise mit 2,5 bar mit Druckluft gefüllt. Zwischen dem Sprinklerrohrnetz und der Löschwasserleitung ist ein Trockenalarmventil geschaltet, dessen Ventilteller aufgrund eines Druckausgleiches zwischen Luftdruck und Wasserdruck geschlossen gehalten wird. Öffnet im Brandfalle ein Sprinkler, dann entweicht die Druckluft aus dem Sprinklerrohrnetz und damit aus der Luftkammer des Trockenalarmventils. Damit wird aufgrund des höheren Druckes des Löschwassers der Ventilteller des Trockenalarmventils geöffnet, so dass sich das Rohrleitungssystem bis zu den Sprinklern mit Löschwasser füllt und sodann zum Löschen eines Brandes aus den Sprinklern austritt. Bis zu dem Zeitpunkt an dem das Löschwasser aus den Sprinklern austritt, vergeht eine Zeit, in der sich ein Brand ausbreiten kann.The invention relates to a fire-extinguishing dry sprinkler system and a method of operating a fire extinguishing dry sprinkler system. Dry sprinkler systems are known. They become many used in frost-prone areas to avoid that a sprinkler pipe network filled with extinguishing water freezes. By means of a compressor is the sprinkler pipe network preferably filled with 2.5 bar with compressed air. Between the Sprinkler pipe network and the extinguishing water pipe is a dry alarm valve switched, the valve disc due to a Pressure equalization between air pressure and water pressure closed is held. Opens a sprinkler in case of fire, then escapes the compressed air from the sprinkler pipe network and thus from the air chamber of the dry alarm valve. This is due to the higher pressure of the fire water of the valve disk opened the dry alarm valve, so that the piping system fills with extinguishing water up to the sprinklers and then to extinguish a fire from the sprinklers emerges. Until that time the extinguishing water from the sprinklers A time passes in which a fire spreads can.
Ein Verfahren und eine Vorrichtung zum Betreiben einer Feuerlösch-Trockensprinkler-Anlage sind beschrieben in der (nicht veröffentlichten) älteren Patentanmeldung DE 196 01 777 A1. Hierbei handelt es sich um eine Feuerlöschanlage mit einem Trockenventil und einem Rohrleitungssystem, das mit Sprinklern verbunden ist. Das Trockenalarmventil wird durch Druckausgleich auf der Luft- und der Löschwasserseite geschlossen gehalten und bei Druckabfall auf der Luftseite geöffnet. Ein von einer Brandmeldezentrale gesteuertes Magnet ventil wirkt einer ausgangsseitigen Druckentlastung der Sprinklerleitung. An dem Trockenalarmventil ist eine Pneumatikkammer vorgesehen, die im Auslösefall über ein Magnetventil entlastet wird und dadurch zusätzlich ein schnelleres Öffnen des Trockenalarmventils bewirkt.A method and apparatus for operating a Fire extinguisher dry sprinkler system are described in the (unpublished) earlier patent application DE 196 01 777 A1. This is a fire extinguishing system with a Drying valve and a piping system with sprinklers connected is. The dry alarm valve will go through Pressure equalization on the air and extinguishing water side closed held and opened at pressure drop on the air side. A magnet controlled by a fire alarm panel Valve acts an output side pressure relief of the Sprinkler. On the dry alarm valve is a Pneumatic chamber provided in the case of release via a solenoid valve is relieved and thereby additionally a faster Opening the dry alarm valve causes.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zu schaffen, mit der das Sprinklerrohrnetz schneller entlüftet und damit die volle Löschwasserleistung schneller an den Sprinklern ansteht.The invention has for its object to provide a device create, with which vented the sprinkler pipe network faster and thus the full extinguishing water faster to the Sprinklers is pending.
Die Feuerlösch-Trockensprinkler-Anlage nach einer ersten Variante
der Erfindung ist durch den Patentanspruch 1 definiert.The fire extinguisher dry sprinkler system according to a first variant
The invention is defined by the
Eine zweite Variante der Erfindung weist die Merkmale des Patentanspruchs
12 auf. A second variant of the invention has the features of the
Bei der ersten Variante erfolgen die Entlüftung des Rohrleitungssystems und die Öffnung des Alarmventiles über getrennte Einrichtungen. Bei der zweiten Variante werden sowohl die Offnung des Alarmventils, als auch die Schnellöffnung für das Entlüften des Rohrleitungssystems von einer Brandmeldezentrale gesteuert. Dabei wird die Schnellöffnung für das Entlüften des Rohrleitungssystems mit elektrisch gesteuerten Mitteln durchgeführt. Die Öffnung des Alarmventils wird pneumatisch oder elektrisch unterstützt.In the first variant done the ventilation of the piping system and the Opening the alarm valve via separate devices. In the second variant, both the opening of the Alarm valve, as well as the quick opening for venting the piping system controlled by a fire alarm panel. Here is the quick opening for the Vent the piping system performed with electrically controlled means. The Opening the alarm valve is pneumatically or electrically supported.
Mit dieser Maßnahme wird erreicht, daß das Löschwasser schneller am Sprinkler ansteht und daß außerdem die einzelnen Sprinklergruppen mit einem Trockenalarmventil volumenmäßig vergrößert werden können.This measure ensures that the extinguishing water is faster at the sprinkler and that also the individual sprinkler groups with a dry alarm valve can be increased in volume.
Bisher wurde mit den Richtlinien vorgeschrieben, daß das Löschwasser nach dem Öffnen eines Sprinklers mindestens innerhalb von 2 Min. dort ansteht. Neuerdings wurde die Richtlinie derart geändert, daß das Wasser bereits innerhalb von 60 Sek. am Sprinkler anstehen muß. Um diese 60 Sek. zu erreichen, konnte das Luftvolumen des Sprinklerrohrsystems maximal 4 m3 betragen.So far, it has been prescribed by the guidelines that the extinguishing water is there after opening a sprinkler at least within 2 min. Recently, the directive has been changed so that the water must already be pending within 60 seconds on the sprinkler. To achieve this 60 sec., The air volume of the sprinkler pipe system could be a maximum of 4 m 3 .
Werden die 60 Sek. nicht erreicht, muß die Sprinklergruppe aufgeteilt und jeder Gruppe, mit einem verkleinerten Volumen, eine gesonderte Trockenalarmventilstation zugeordnet werden. If the 60 seconds are not reached, the sprinkler group must be divided and each group, associated with a reduced volume, a separate dry alarm valve station become.
Mit der Erfindung wird erreicht, daß aufgrund der schnelleren Entlüftung des Rohrleitungssystems und der schnelleren Öffnung des Trockenalarmventils die Ventilgruppe volumenmäßig vergrößert und damit weniger Trockenalarmventilstationen zu installieren sind. Aufgrund des erfindungsgemäßen Verfahrens wird auch der Investitionsaufwand verringert.With the invention it is achieved that due to the faster venting of the Piping system and the faster opening of the dry alarm valve the Valve group increases in volume and thus fewer dry alarm valve stations to install. Due to the inventive method is also the Capital expenditure reduced.
