Description
Auslöseglied für einen SprinklerTrigger link for a sprinkler
Die Erfindung betrifft ein Auslöseglied für einen Sprinkler für eine ortsfeste Feuerlöschanlage, wobei das aus einem Glasfäßchen bestehende und mit einer Sprengflüssigkeit gefüllte Auslöseglied den Ventilteller des Sprinklers geschlossen hält.The invention relates to a trigger element for a sprinkler for a fixed fire extinguishing system, wherein the trigger element, which consists of a small glass vessel and is filled with an explosive liquid, the valve disk keep the sprinkler closed.
Derartige Sprinkler sind seit vielen Jahrzehnten bekannt. Im Brandfalle wird die Sprengflüssigkeit von der Glaswand erwärmt, die ihrerseits von den Rauchgasen aufgewärmt wird. Zufolge der Wärmeaufnahme dehnt sich die Sprengflüssigkeit aus und übt damit von innen her einen Sprengdruck auf das Glasfäßchen aus.Such sprinklers have been known for many decades. In the event of a fire, the explosive liquid is heated by the glass wall, which in turn is heated by the smoke gases is warmed up. As a result of the heat absorption, the explosive liquid expands and thus exerts itself from the inside exerted a pressure on the glass vial.
Das Glasfäßchen muß eine bestimmte Wandstärke aufweisen, um damit den mechanischen Druck auszuhalten, der zum Verschließen des Sprinklers erforderlich ist. Je dicker die Glaswand des Auslösegliedes ist, um so länger ist die Zeitspanne, die erforderlich ist, die Sprengflüssigkeit auf Sprengdruck-Temperatur aufzuwärmen. Um diese Zeitspanne zu verkürzen, hat man dieThe glass vessel must have a certain wall thickness in order to withstand the mechanical pressure that is required to close the sprinkler. The thicker the glass wall of the release link, the longer it is is the time it takes to warm up the blasting liquid to blasting pressure temperature. To shorten this period of time, you have the
Wandstärke der Glasfäßchen immer dünner gemacht. Eine weitere Verdünnung der Glaswand ist aus Festigkeitsgründen nicht mehr möglich. Wall thickness of the glass vials made thinner and thinner. A further thinning of the glass wall is no longer possible for reasons of strength.
Der Erfindung liegt die Aufgabe zugrunde, die Auslösegeschwindigkeit eines Sprinklers zu erhöhen, um damit den Sprinkler sensibler zu machen.The invention is based on the object of the release speed of a sprinkler to make the sprinkler more sensitive.
Diese Aufgabe wird dadurch gelöst, daß innerhalb des Glasfäßchens ein Verdrängerkörper angeordnet ist, der aus einem Material mit einem Wärmeaufnahme-Vermögen besteht, das geringer ist als das Wärmeaufnahme-Vermögen der Sprengflüssigkeit. Der Verdrängerkörper kann beispielsweise aus Polytetrafluorethylen bestehen. Der Verdrängerkörper schwimmt lose innerhalb der Sprengflüssigkeit.This object is achieved in that a displacement body is arranged within the glass vessel, the consists of a material with a heat absorption capacity that is less than the heat absorption capacity the blasting liquid. The displacement body can for example consist of polytetrafluoroethylene. The displacer floats loosely within the explosive liquid.
Mit dieser Maßnahme wird das Volumen der Sprengflüssigkeit bei unveränderter mechanischer Festigkeit des Glasfäßchens wesentlich verringert. Die geringere Flüssigkeitsmenge nimmt schneller die Temperatur an, die zur Sprengung des Glasfäßchens erforderlich ist.With this measure, the volume of the explosive liquid is maintained with the mechanical strength of the Glass vial significantly reduced. The smaller amount of liquid takes on the temperature faster, which is necessary to blow up the glass vial.
Damit öffnet ein erfindungsgemäß ausgebildeter Sprinkler im Brandfalle schneller als die bisherigen Sprinkler ohne Verdrängerkörper.A sprinkler designed according to the invention thus opens faster than previous sprinklers in the event of a fire without displacer.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im nachfolgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below described.
Das Auslöseglied 1 besteht aus einem geschlossenen Glasfäßchen 2 mit einer bestimmten Wanddicke 3. Nachdem die Sprengflüssigkeit 5 eingefüllt und der Verdrängerkörper 6 eingelegt ist, wird das Ende 4 des Fäßchens 2 verschlossen. Mit 7 ist die übliche Luftblase bezeichnet.The trigger element 1 consists of a closed glass vessel 2 with a certain wall thickness 3. After the explosive liquid 5 is filled and the displacement body 6 is inserted, the end 4 of the Vessel 2 closed. With 7 the usual air bubble is referred to.
