- the device according to the invention is applicable wherever sprinkler systems, in particular sprinkler drying systems, are present. This is the case in frost-prone areas or in areas with very high temperatures.
- Pipe nets of sprinkler drying plants are filled with compressed air or inert gas. Only after opening a sprinkler does water get into the pipe network.
- Hanging sprinklers in particular for frost-prone areas of a sprinkler system, are for example out DE 28 26 141 A1 known. So that water can escape from the open sprinkler even at low temperatures, fillers such as granules, liquid, alcohol or brine can be added to the piping network in front of the sprinkler so as to ensure that the extinguishing water can escape without difficulty.
- fillers such as granules, liquid, alcohol or brine can be added to the piping network in front of the sprinkler so as to ensure that the extinguishing water can escape without difficulty.
- a solution is described in which a jarred granulate is arranged in the downpipe of the sprinkler, which is discharged with the extinguishing water after triggering of the sprinkler.
- DE 10 2005 043 213 B4 describes a sprinkler system for frost-prone or cooled areas, in which extinguishing water and antifreeze are in the lines to the sprinkler, with antifreeze is located in the lower part of the downpipe in front of the sprinkler in the frost-prone area.
- dry sprinklers whose supply lines are empty and depressurized.
- the seal at the water connection is made mechanically via a rod or a pipe directly through the opposite, bursting at a certain temperature glass ampoule.
- the mechanical dry sprinklers are preferred in practice, since there is no risk of unnoticed entry of water, which could cause the dry sprinkler to fail at low temperatures.
- Dry alarm valves serve a sprinkler piping network to separate the low air / gas pressure of the pipe network to produce against the high pressure of the water supply and release the flap to the water supply at falling pressure in Sprinklerrohrnetz after opening a sprinkler via a lever mechanism, so that the extinguishing water can flow to the sprinklers.
- a lever mechanism is also known for triggering a sprinkler. So is in CH 662281 A a sprinkler described in which a lever assembly serves as a trigger mechanism for a sprinkler.
- US 2010/0038099 describes and shows a device for triggering a fire extinguishing system by a sprinkler, wherein the device between the conduit for the extinguishing agent and the sprinkler is arranged.
- the device consists of a multi-arm joint, which deflects a force over the axis of a disc.
- the joint described and illustrated is not a toggle joint because the effects of a bellcrank (translation of a force or a path) are not met by this device, but the movement or force is directed through the device only in a different direction ,
- SU 1025435A Although shows a toggle joint, which is arranged between a sprinkler and the associated spray plate, however, this toggle joint is not a toggle joint, which is arranged between a sprinkler and a pipe for the extinguishing agent.

- the load axis of the trigger element corresponds in some of the axis of symmetry of the vertically suspended sprinkler.
- a multi-armed toggle joint is understood to mean a multi-arm joint with which a force or a travel is translated, that is to say that a change in the acting force or of the travel is achieved via the toggle joint.
- amplification or reduction of the acting force or a shortening or lengthening of the way over the toggle joint can be achieved.
- the sealing element seals the pipeline for the extinguishing agent gas-tight. It can be a valve disk against which the multi-arm toggle joint acts.
- an adjusting device with respect to the sealing element or the valve disk.
- This may be an adjustment screw on the opposite end wall.
- Other suitable devices that fulfill the purpose of adjusting the pressure on the valve disk, are conceivable.
- the toggle joint can be a multi-armed as a two- or four-armed toggle joint.
- the four-armed toggle joint consists of four Articulated arms and four joints. The articulated arms and the joints are each arranged opposite one another, so that the toggle joint forms a kind of parallelogram.
- hinge connections can be arranged horizontally or vertically on the supports or bearing surfaces.
- the articulated arms may be rods or tubes made of steel, plastic or light metal.
- joint connections which act on the closure of the sprinkler and on the housing
- joint connections which act on the sealing element or the valve disk and the adjusting device or the housing wall.
- connection adapter on the pipeline for the extinguishing agent.
- the solution according to the invention has the advantage that dry sprinklers whose ampoules can absorb only small mechanical forces can also be arranged for use on pipelines, which have large inlet cross sections, large volume flows and high pressures, since the forces occurring from the pipeline only partially must be taken by the sprinkler ampule. Furthermore, it is advantageous that the sealing force of the sealing element can be adjusted by means of an actuator.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a device according to the preamble of the first claim.
Die erfindungsgemäße Vorrichtung ist überall dort anwendbar, wo Sprinkleranlagen, insbesondere Sprinkler-Trockenanlagen, vorhanden sind. Das ist in frostgefährdeten Bereichen oder in Bereichen mit sehr hohen Temperaturen der Fall.The device according to the invention is applicable wherever sprinkler systems, in particular sprinkler drying systems, are present. This is the case in frost-prone areas or in areas with very high temperatures.
Rohrnetze von Sprinkler-Trockenanlagen sind mit Druckluft oder Inertgas gefüllt. Erst nach Öffnen eines Sprinklers gelangt Wasser in das Rohrnetz.Pipe nets of sprinkler drying plants are filled with compressed air or inert gas. Only after opening a sprinkler does water get into the pipe network.
Hängende Sprinkler, insbesondere für frostgefährdete Bereiche einer Sprinkleranlage, sind beispielsweise aus
Üblich sind auch Trockensprinkler, deren Zuleitungen leer und drucklos sind. Die Abdichtung am Wasseranschluß erfolgt mechanisch über eine Stange oder ein Rohr direkt durch die gegenüberliegende, bei einer bestimmten Temperatur platzende Glasampulle. Die mechanisch arbeitenden Trockensprinkler werden in der Praxis bevorzugt, da hier nicht die Gefahr des unbemerkten Eintritts von Wasser besteht, die den Trockensprinkler bei niedrigen Temperaturen versagen lassen könnten.Also common are dry sprinklers whose supply lines are empty and depressurized. The seal at the water connection is made mechanically via a rod or a pipe directly through the opposite, bursting at a certain temperature glass ampoule. The mechanical dry sprinklers are preferred in practice, since there is no risk of unnoticed entry of water, which could cause the dry sprinkler to fail at low temperatures.
Hebelmechanismen im Zusammenhang mit Feuerlöschanlagen sind grundsätzlich bei Trockenalarmventilen für Sprinklerrohrnetze bekannt und beispielsweise in
Ein Hebelmechanismus ist auch zum Auslösen eines Sprinklers bekannt. So ist in
Aus
Sprinklerampullen oder Auslöseelemente weisen bei jüngsten Entwicklungen nur noch einen geringen Durchmesser auf. Die zu verschließenden Öffnungen zu den Rohrleitungen werden zugunsten der gewünschten höheren Durchflussmengen immer größer, was dazu führt, daß Auslöseelemente mit geringem Durchmesser nicht mehr eingesetzt werden können, da sie vor Erreichen ihrer Auslösetemperatur durch den anstehenden Druck in der Rohrleitung bersten könnten.Sprinklerampullen or tripping elements have in recent developments only a small diameter. The openings to be closed to the pipes are becoming larger in favor of the desired higher flow rates, with the result that tripping elements with small diameter can not be used because they could burst before reaching their release temperature by the pressure in the pipeline.
Möglichkeiten, einen Trockensprinkler in einem Rohrleitungssystem mit einem großen Eintrittsquerschnitt an einen Sprinkler mit einer Ampulle mit einem geringen Durchmesser einzusetzen, zeigen die genannten Lösungen nicht auf.Possibilities to use a dry sprinkler in a piping system with a large inlet cross-section of a sprinkler with a small diameter ampoule, not show the solutions mentioned.
Es ist daher Aufgabe der Erfindung, eine Vorrichtung zum Auslösen einer Feuerlöschanlage mittels Sprinkler zu entwickeln, mit der die aus dem Druck der Löschanlage resultierende Kraft, die über der Lastaufnahmefähigkeit des abstützenden wärmeempfindlichen Elementes liegt, so verringert wird, daß die auf das wärmeempfindliche Element wirkende abzustützende Last das wärmeempfindliche Element nicht vorzeitigt auslöst.It is therefore an object of the invention to develop a device for triggering a fire extinguishing system by means of sprinklers, with which the force resulting from the pressure of the extinguishing system, which is above the load-carrying capacity of the supporting heat-sensitive element, is reduced so that acting on the heat-sensitive element to be supported load the thermosensitive element does not prematurely triggers.
Diese Aufgabe wird durch eine Vorrichtung nach den Merkmalen des ersten Patentanspruches gelöst.This object is achieved by a device according to the features of the first claim.
Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.Subclaims give advantageous embodiments of the invention again.
Die erfindungsgemäße Lösung sieht eine Vorrichtung zum Auslösen einer Feuerlöschanlage durch einen Sprinkler vor, die zwischen der Rohrleitung für das Löschmittel und dem Sprinkler angeordnet ist. Erfindungsgemäß handelt es sich um ein mehrarmiges Kniehebel-Gelenk, welches zwischen der Belastungsachse des Auslöseelements und einem Abdichtelement und einem Winkel zwischen 100 und 80 Grad, vorzugsweise im etwa rechten Winkel angeordnet ist.The solution according to the invention provides a device for triggering a fire extinguishing system by means of a sprinkler, which is arranged between the pipeline for the extinguishing agent and the sprinkler. According to the invention is a multi-arm toggle joint, which is disposed between the load axis of the trigger element and a sealing member and an angle between 100 and 80 degrees, preferably at approximately right angles.
Die Belastungsachse des Auslöseelements entspricht in etwas der Symmetrieachse des senkrecht hängenden Sprinklers.The load axis of the trigger element corresponds in some of the axis of symmetry of the vertically suspended sprinkler.
Unter einem mehrarmigen Kniehebelgelenk ist ein mehrarmiges Gelenk zu verstehen, mit dem eine Kraft oder ein Weg übersetzt wird, das heißt, dass über das Kniehebelgelenk eine Änderung der wirkenden Kraft oder des Weges erreicht wird. Somit kann ein Verstärken oder ein Reduzieren der wirkenden Kraft bzw. eine Verkürzung oder Verlängerung des Weges über das Kniehebelgelenk erreicht werden.A multi-armed toggle joint is understood to mean a multi-arm joint with which a force or a travel is translated, that is to say that a change in the acting force or of the travel is achieved via the toggle joint. Thus, an amplification or reduction of the acting force or a shortening or lengthening of the way over the toggle joint can be achieved.
Das Abdichtelement verschließt die Rohrleitung für das Löschmittel gasdicht. Es kann sich dabei um einen Ventilteller handeln, gegen den das mehrarmige Kniehebel-Gelenk wirkt.The sealing element seals the pipeline for the extinguishing agent gas-tight. It can be a valve disk against which the multi-arm toggle joint acts.
Vorteilhaft ist es, gegenüber dem Abdichtelement oder dem Ventilteller eine Einstelleinrichtung anzuordnen. Das kann eine Einstellschraube an der gegenüberliegenden Stirnwand sein. Andere geeignete Einrichtungen, die den Zweck erfüllen, den Druck auf den Ventilteller einzustellen, sind denkbar.It is advantageous to arrange an adjusting device with respect to the sealing element or the valve disk. This may be an adjustment screw on the opposite end wall. Other suitable devices that fulfill the purpose of adjusting the pressure on the valve disk, are conceivable.
Bei dem Kniehebel-Gelenk kann es sich um ein mehrarmiges wie ein zwei- oder vierarmiges Kniehebel-Gelenk handeln. Das vierarmige Kniehebelgelenk besteht aus vier Gelenkarmen und vier Gelenkverbindungen. Die Gelenkarme und die Gelenkverbindungen sind jeweils gegenüberliegend angeordnet, so daß das Kniehebel-Gelenk eine Art Parallelogramm bildet.The toggle joint can be a multi-armed as a two- or four-armed toggle joint. The four-armed toggle joint consists of four Articulated arms and four joints. The articulated arms and the joints are each arranged opposite one another, so that the toggle joint forms a kind of parallelogram.
Vorteilhaft ist es, die Gelenkverbindungen als punktförmige Verbindung auszuführen, die jeweils mittig gegen ihre Auflagepunkte wirken. Denkbar sind aber auch scharnierartige Gelenke oder eine Kombination von scharnierartigen und/oder punktförmigen Gelenkverbindungen. Die Scharnierverbindungen können waagerecht oder senkrecht auf den Auflagen oder Auflageflächen angeordnet sein. Bei den Gelenkarmen kann es sich um Stangen oder Rohre aus Stahl, Kunststoff oder Leichtmetall handeln.It is advantageous to perform the joints as a point-like connection, each acting centrally against their support points. However, hinge-like joints or a combination of hinge-like and / or punctiform joint connections are also conceivable. The hinge connections can be arranged horizontally or vertically on the supports or bearing surfaces. The articulated arms may be rods or tubes made of steel, plastic or light metal.
Gegenüber angeordnet sind jeweils die Gelenkverbindungen, die auf den Verschluß des Sprinklers und auf das Gehäuse wirken, und die Gelenkverbindungen, die auf das Abdichtelement oder den Ventilteller und die Einstelleinrichtung oder die Gehäusewand wirken.Opposite are arranged in each case the joint connections, which act on the closure of the sprinkler and on the housing, and the joint connections, which act on the sealing element or the valve disk and the adjusting device or the housing wall.
Vorteilhaft ist es, zwischen Sprinkler und Kniehebel-Gelenk ein Fall- und ein Stützrohr anzuordnen. Das erlaubt, den Sprinkler beispielsweise an einer Seite einer Wand anzuordnen und die Rohrleitung an der anderen Seite einer Wand.It is advantageous to arrange a drop and a support tube between sprinkler and toggle joint. This allows the sprinkler to be placed, for example, on one side of a wall and the pipe on the other side of a wall.
Weiterhin ist es vorteilhaft, das mehrarmige Kniehebel-Gelenk in einem T-förmigen Gehäuse anzuordnen.Furthermore, it is advantageous to arrange the multi-arm toggle joint in a T-shaped housing.
Darüber hinaus wird es als vorteilhaft angesehen, an der Rohrleitung für die Löschmittel einen Anschlußadapter anzuordnen.In addition, it is considered advantageous to arrange a connection adapter on the pipeline for the extinguishing agent.
Die erfindungsgemäße Lösung hat den Vorteil, daß Trockensprinkler, deren Ampullen nur geringe mechanische Kräfte aufnehmen können, auch für den Einsatz an Rohrleitungen angeordnet sein können, die große Eintrittsquerschnitte, große Volumenströme und hohe Drücke aufweisen, da die auftretenden Kräfte aus der Rohrleitung nur zum Teil von der Sprinklerampulle aufgenommen werden müssen. Weiterhin ist vorteilhaft, daß die Dichtkraft des Abdichtelementes mittels Stellgliedes eingestellt werden kann.The solution according to the invention has the advantage that dry sprinklers whose ampoules can absorb only small mechanical forces can also be arranged for use on pipelines, which have large inlet cross sections, large volume flows and high pressures, since the forces occurring from the pipeline only partially must be taken by the sprinkler ampule. Furthermore, it is advantageous that the sealing force of the sealing element can be adjusted by means of an actuator.
