Description

Component for a fire protection system, method for producing the same and fire protection system with selbiger

The present invention relates to a component for a fire protection system with a housing.

Fire protection systems of the aforementioned type are known. Such fire protection systems can be, for example, but not exclusively, fire extinguishing systems, spark extinguishing systems, fire alarm systems, smoke extraction systems and / or a combination of these. Here are fire extinguishing systems permanently operational facilities that serve for the distribution of extinguishing agents to extinguish by the extinguishing agent already formed fires.

Spark extinguishing systems, on the other hand, serve preventive fire protection by detecting and switching off potential firing initiators before the fire even starts. To this end, spark extinguishing systems have so-called spark detectors, which detect the heat radiation emitted by the sparks or other firing initiation and thus detect them. When sparks or other firing initiations are detected, the spark detectors then send a corresponding signal to a radio control center of the spark extinguishing system. The radio control center then initiates the deletion process.

Fire alarm systems are also used for preventive fire protection. Fire alarm systems usually include a fire alarm panel and one or more fire alarms, which serve the detection of fire events. This fire alarm can be configured here as a fire gas or flue gas detector, as a smoke detector, as a flame detector and / or as a heat detector.

In response to the detection of a (potential) fire event, the fire alarm center receives a corresponding signal from the one or more corresponding fire detectors. The fire panel then causes an output of a danger message by the fire alarm system. In response to such a hazard message, a number of different actions can then be taken, such as triggering an alarm, alerting a fire department, closing fire protection shutdowns, triggering an extinguishing system, or the like. In this way, fires or Zündinitiale can be detected at an early stage in places where no people at the time. A further spread can be prevented if necessary.

Smoke extraction systems serve to dissipate smoke that arises in the event of fire from the interior of a building to the outside. Smoke extraction systems can be triggered manually and / or automatically by the above-mentioned fire alarm and / or the fire alarm system. Alternatively or additionally, tripping may also be effected by thermal triggers, ie temperature-sensitive elements. Typically, smoke extraction systems should be able to be triggered in particular manually. An automatic release mechanism can be added depending on the requirements of the smoke extraction system.

All these systems have in common that they serve the fire protection, in particular the prevention and / or containment of fires. In the case of such fires usually heat in the area of the fire protection system. It is essential that the fire protection systems still function reliably even when the heat is generated. This requires in particular that certain components of the fire protection system maintain their functionality even at high temperatures.

Such components for a fire protection system may in particular be components that are installed inside the fire protection system, especially water-bearing components of a fire protection system such as valves or the like. Alternatively or additionally, such components may also be electronic components used for controlling the fire protection system or comparable applications become. The electronic components are here dressed Favor, so that the electronics is not damaged when initiating a deletion process. In particular, these can be disguised electronic components that are housed within the room in which the fire protection system is installed. As a first example, electronics cabinets are to be mentioned in which circuits or the like are housed, for example, serve the control of the fire protection system and should therefore retain their functionality even in case of fire. Another example is cooling systems that serve, for example, the cooling of electronics or other elements and for which it is also advantageous that their functionality is maintained in case of fire. To ensure the heat resistance of these components, it is common to make them from materials or to dress them with materials that have a very high melting temperature. The materials to be used for this purpose are defined in particular by corresponding standards and guidelines, such as fire protection standards for stationary extinguishing systems such as the VdS CEA 4100 guidelines, which must be complied with in the manufacture and / or lining of the components. Conventional materials for producing a housing or a cladding of these components are, for example, cast iron or brass. The connectors, especially pipes, between the components and the fire alarm system are typically made of steel.

These materials have on the one hand a high melting temperature and thus a high heat resistance, on the other hand they are characterized by a high strength. This combination of high melting temperature and strength makes the mentioned materials particularly suitable for use in fire protection systems.

A disadvantage of these materials, however, is their high specific gravity. Especially in the case of larger components, these have, due to the high specific weight of the material from which they are made, usually a very high weight on. This causes on the one hand, that the production of components made of these materials is relatively expensive, on the other hand, the handling of the components during transport, during installation and / or maintenance is difficult. This increased effort in manufacturing and / or transport causes an increase in the cost of manufacturing and distribution of components.

Another disadvantage of the materials commonly used is also their susceptibility to corrosion. This causes the components to be additionally need to be coated corrosion protection, which requires a further step in the manufacturing process and additional material costs This increases the cost of manufacturing even further.

It is therefore desirable to replace the currently used materials with materials which do not have these disadvantages. Against this background, the invention is therefore the object of further developing the above-mentioned components for a fire protection system so that they can be manufactured and transported more efficiently and inexpensively, and facilitate easier handling during installation, maintenance and / or transport. The invention solves the underlying object in a first aspect, in which at least one nozzle for discharging extinguishing fluid is arranged on the component on the housing or in the vicinity of the housing, wherein the nozzle is connectable to an extinguishing fluid supply.

The invention is based on the recognition that there are already a large number of materials which have a lower specific weight compared to the materials customarily used for the abovementioned components, but at the same time have comparable properties in terms of their strength. However, the necessary melting temperatures of these lighter materials are too low to use for the manufacture of components for fire protection systems. It was recognized that the problem of lower melting temperature for lighter materials can be circumvented by providing the components with a self-protection mechanism in the form of a nozzle for applying extinguishing fluid to the heat generated in a fire. By applying extinguishing fluid, the component is cooled in case of fire, whereby the melting of the component can be prevented, even if it is made of a material having a lower melting temperature than that of the previously customary materials. According to the invention, it is provided that the temperatures at the component in the event of a fire in particular below a threshold of 200 ° C, even more preferably to keep below a threshold of 100 ° C. For this purpose, it is necessary to discharge the extinguishing fluid with the appropriate operating pressure of the nozzle, and thus in an appropriate amount, from the nozzle. Depending on the nozzle should be Operating pressure here above 5 bar, preferably above 10 bar, more preferably above 15 bar. For example, a K40 sprinkler could be used as the nozzle. At an operating pressure of 16 bar, 160 liters of extinguishing fluid can escape from the sprinkler per minute. Such an amount should be sufficient to cool the component provided with the nozzle (the K40 sprinkler) to below 100 ° C.

According to the invention, it is provided that, in the event of fire, an extinguishing fluid escapes through the nozzle. The fact that the nozzle is mounted on the housing or in the vicinity of the housing, the discharged through the nozzle extinguishing fluid passes directly to the component, or to the housing of the component. By deleting fires on the housing or in the vicinity of the housing, the heat generated by the fire is reduced and prevents melting and / or deformation of the component or the housing of the component. As a result, materials with a lower melting temperature, such as light metals or plastics, can be used for the components. According to the invention, a nozzle is to be understood as any type of protective element from which an extinguishing fluid having a predetermined performance characteristic can flow. In particular, the nozzle can be designed as a sprinkler or extinguishing nozzle. Particularly preferably, the nozzle can be designed as a standing sprinkler, which is arranged on the housing of the component. A sprinkler here is to be understood as a sprinkler head. Such sprinkler heads are supplied with a quenching fluid by a fluid supply, usually a sprinkler system. In the normal state, the sprinklers are closed with a temperature-sensitive element, such as a glass ampule filled with a liquid. In case of fire, the liquid inside the glass ampule heats up and expands. The ampoule bursts, causing the sprinkler to open and the extinguishing fluid to escape. The nozzle can also be designed as an extinguishing nozzle. Such extinguishing nozzles are typically arranged on extinguishing fluid supply lines such as pipes. By introducing an extinguishing fluid into the extinguishing fluid supply line, the extinguishing nozzle is exposed to the extinguishing fluid and thereby triggered. Extinguishing nozzles are often used in spark extinguishing systems. In some embodiments, the triggering may also be performed by a temperature meter that detects the temperature at and in the vicinity of the nozzle and / or the component and triggers at a certain temperature. The triggering temperature can preferably correspond to the triggering temperature of the extinguishing fluid outlets of the fire protection system. In some embodiments, the trip temperature is 60 to 70 ° C. Alternatively or additionally, the triggering temperature may also be below or above the triggering temperature of the extinguishing fluid outlets of the fire protection system. In some embodiments, the triggering of the at least one nozzle can also be effected by means of an electronic circuit. Here, the electronic circuit is preferably set up so that it transmits a corresponding signal to the nozzle when it is determined that a cooling of the component is necessary. In response to the signal, the nozzle can then be triggered. According to the invention, the nozzle can be arranged directly on the housing of the component. This can be done directly in the manufacturing process with the nozzle attached to the housing during fabrication. Alternatively, it is also possible to retrofit a housing with such a nozzle to equip, for example, a component subsequently protected against fire. Alternatively, the nozzle can be arranged in the vicinity of the housing. In this case, the near zone should be chosen such that it is ensured that the extinguishing fluid discharged through the nozzle reaches the component which is to be protected by the nozzle. Furthermore, the extinguishing fluid should be able to reach the area around the component, in particular into the area below the component. In this case, the near zone is to be selected such that it encompasses the region in which it can be ensured that the component is cooled by the extinguishing fluid emerging from the nozzles in such a way that the component or its housing can be made of a material , which has a melting temperature of less than 800 ° C. The nozzles should therefore be arranged so that they can accomplish a sufficient cooling of the component. For this purpose, the short-range area comprises in particular a range of 1 to 100 cm around the housing. This means that the nozzle is placed at a distance of 1 to 100 cm from the housing.

Preferably, the near zone comprises a range of 1 to 50 cm. The advantage of attaching the nozzle at a distance of at most 50 cm from the housing is that at this distance a very good distribution of the extinguishing fluid over the entire component can be achieved, since the extinguishing fluid spread on the way from the nozzle to the component can. Still more preferably, the near zone comprises a range of 1 to 20 cm around the housing. Advantage of this preferred embodiment, in which the nozzle is arranged at a maximum distance of 20 cm from the housing, is the good adjustability of the extinguishing surface of the extinguishing fluid. That is, the alignment of the nozzle to the effect that the extinguishing fluid can be distributed as evenly as possible over the component, is greatly facilitated at a distance of 20 cm maximum. In particular, here depending on the desired adjustability and available space, the nozzle at a distance of 1 or 2 cm from the housing, or even at a distance of 3, 4, 5, 6, 7, 8, 9 or 10 cm, or each Distance between 10 and 20 cm can be arranged. The extinguishing fluid discharged through the nozzle may be configured as an extinguishing liquid, such as water, or water with additives (eg, foam). Alternatively, the quenching fluid may also be gaseous or comprise a mixture of a gas and a liquid. In a specific embodiment, the quenching fluid may comprise perfluoro-2-methyl-3-pentanone (C6F12O). The advantage of this extinguishing fluid is that it can also be used to extinguish metals or the like.

The application of the extinguishing fluid according to the invention serves both the cooling of the component and the fire fighting. This means, on the one hand causes the applied to the component and distributed in the vicinity of the component extinguishing fluid, a reduction in the temperature of the component - in particular of the housing - and on the other causes the (then) spent on the fire extinguishing fluid, which previously or simultaneously the cooling the component serves, a fire fighting in the area of the component. In some embodiments, the effect of the quenching fluid is such that there is a ratio of 60% cooling to 40% firefighting.

Advantageously, the extinguishing fluid is applied to the component and into the vicinity of the component for a certain time in order to ensure satisfactory cooling and firefighting. This time may in particular depend on the nature and extent of the fire event.

The invention is advantageously developed, in which the housing is completely or partially formed from a material having a melting temperature of less than 800 ° C. In a further preferred embodiment, the housing is completely or partially formed from a plastic and / or a light metal. Preferably, the housing of the component is completely or partially made of a material having a melting temperature of less than 800 ° C. In this case, materials are particularly suitable which have the lowest possible specific weight and high strength. Plastics and / or light metals that meet these requirements for weight and strength are considered to be particularly advantageous in this context.

The advantage of using a plastic and / or light metal for complete or partial production of the housing is that these materials are very easy to manufacture and do not require additional corrosion protection. Furthermore, these materials have a lower specific weight, so that the housing made of them for the components have a reduced weight compared to the prior art. This facilitates handling during transport, as well as during installation and maintenance. By using a plastic and / or a light metal, therefore, on the one hand, costs and outlay on production can be reduced and, on the other hand, the costs for transport and the expenditure on installation.

A particularly preferred plastic for the production of components for a fire protection system is a material from the group of polyamides with a glass fiber content. Polyamides in a fiber composite with glass fibers have very good mechanical properties. In particular, the strength and impact resistance of this combination can be tailored to the application by adapting the fiber composite.

A light metal suitable for use in a component for a fire protection system is, for example, aluminum, but other light metals such as titanium may also be used. In a preferred embodiment, the component for a fire protection system is made of aluminum and water is used as extinguishing fluid. In case of fire, the component is cooled accordingly by applying water by means of the nozzles, preferably below 100 ° C, and prevents melting of the component.

The molding of the housing for the component of the material, in particular the plastic and / or the light metal can be achieved by a variety of methods by which the material can be brought into the desired shape. Examples of such methods are casting, bending, printing, milling, joining, or the like. In this case, the shaping furthermore also includes the provision of housing openings and housings. seanschlüssen for connection to other components, such as the fire protection system. For example, the molding of the housing can be carried out by means of a casting process. For this purpose, different casting methods such as casting, ingot casting, continuous casting, or the like can be used. When molding, the mold filling can be done by gravity casting, centrifugal casting or die casting, depending on the desired result and existing manufacturing equipment. The molding of the housing can also be done by means of a method from the group Bending. Again, different bending methods, such as free bending, swaging, roll bending, swivel bending or the like, applicable. Alternatively or additionally, the molding of the housing can also be carried out by means of additive manufacturing. The housing is built up layer by layer on the basis of digital 3D design data by depositing material. Advantage of this manufacturing process is the reduced cost of materials, as instead of for example to separate pieces from a block to obtain openings and channels, the channels are built up layer by layer from the outset.

In a further preferred embodiment, the component comprises an extinguishing fluid inlet, which is fluid-conductively connected to the nozzle.

Under an extinguishing fluid inlet in the context of the invention, each inlet for the extinguishing fluid to understand. This extinguishing fluid inlet preferably serves to supply the nozzle. In this case, the inlet can be configured as an opening in the housing of the component, the fluid-conducting connection being provided by a fluid-conducting channel running in the interior of the housing or on the housing. The extinguishing fluid inlet may be further equipped with a seal and a fitting. In this way, a fluid-tight connection to an extinguishing fluid supply, for example a fire-extinguishing system or a separate supply system, can be ensured.

Preferably, the extinguishing fluid inlet is arranged on the housing of the component and the channel for the fluid-conducting connection between the extinguishing fluid inlet and the nozzle runs in the interior of the component. This embodiment is particularly advantageous in the case of fluid-conducting components for the fire protection system. These fluid-conducting components usually already have an extinguishing fluid inlet for the fluid line. Further, by arranging this extinguishing fluid inlet to supply the nozzle with extinguishing fluid, the number of housing openings of the housing for the component can be reduced, thereby reducing the manufacturing cost. In some embodiments, the nozzle may be here be supplied directly by the extinguishing fluid supply to the component with extinguishing fluid. Alternatively or additionally, the supply can be effected by the fluid channel extending in the interior or exterior of the component, which establishes the fluid-conducting connection between the extinguishing fluid inlet and the nozzle. In some embodiments, the fluid channel also serves to connect the quench fluid supply of the component to the nozzle.

Likewise preferably, the extinguishing fluid inlet is arranged on the housing of the component or directly on the nozzle, so that the channel for the fluid-conducting connection between the extinguishing fluid inlet and the nozzle extends outside the component. In this case, the channel for the fluid-conducting connection can be provided, for example, by a tube running outside the component or a tube lying outside the component. This embodiment is particularly advantageous for components that are not fluid-conducting and in which it is undesirable for the quenching fluid to enter the interior of the component, such as electronic components. According to a preferred embodiment, the nozzle comprises a plurality of nozzle outlet openings, at least one triggering device and an alignment element, wherein the plurality of nozzle outlet openings are arranged in a geometrically predetermined arrangement on the alignment element.

It is preferred that the nozzle can deploy the quenching fluid as evenly as possible on the housing and in the area around the housing. Such a uniform application can be achieved in particular in that the nozzle comprises a plurality of nozzle outlet openings, from which the extinguishing fluid can be discharged.

These nozzle outlet openings are arranged in a geometrically predetermined arrangement on the nozzle. Here, the term geometrically predetermined to mean that the Düsenauslassöffnungen are arranged according to a predetermined pattern on the alignment element. This pattern preferably determines the distance between the individual nozzle outlet openings to one another, how many nozzle outlet openings are arranged on the alignment element and on which position of the alignment element the nozzle outlet openings are arranged.

In this case, the nozzle outlet openings can in particular in the direction of a bottom surface and / or in the direction of a ceiling surface and / or in the direction of a side wall of a Be aligned. The nozzle outlet openings can therefore be arranged on the upper side and / or the lower side and / or on the sides of the alignment element-and thus of the nozzle. In this case, the alignment element can in particular be selected such that the nozzle outlet openings are aligned in different directions, ie in the direction of the top side and / or bottom side and / or to the sides.

In this case, the arrangement of the nozzle outlet openings and the shaping of the alignment element can preferably be effected as a function of the component to be protected, that is to be cooled, since different components can have different geometries and thus require different extinguishing characteristics for the extinguishing fluid in order to cool the component efficiently can. Since the alignment element and the geometrical arrangement of the nozzle outlet openings determine the directional characteristic of the extinguishing fluid for the nozzle, they must always be selected such that they permit optimum extinguishing-fluid application to the component to be protected.

In some embodiments, the alignment element is disposed at or near the housing. In this case, the alignment element can in particular be designed so that it can be attached to an extinguishing fluid supply line of the component. In these cases, the alignment element is preferably formed annular. In some embodiments, the geometry of the placement member may also be non-annular, but rectangular, triangular, or the like. The geometry here is always to be determined with regard to the geometry of the component to be protected and the position at which the alignment element is to be attached. In some embodiments, position of the alignment member, geometry of the component, and geometric arrangement of the nozzle outlet openings are correlated to determine the optimum nozzle formation. Under a triggering device is understood here an element of the nozzle, which is adapted to activate the extinguishing fluid supply for the nozzle, so trigger. For this purpose, such a triggering device can in particular comprise a closure element, which in the closed, ie not triggered, state is in a closure position in which a nozzle connection opening of the extinguishing fluid supply line is closed, so that no extinguishing fluid can enter the nozzle. In the triggered state, the closure element is moved from the closure position to an open position in which the closure element releases the quench fluid flow from the quench fluid supply line through the nozzle port. For this purpose, the triggering device may further comprise a triggering element, in particular a thermal or electrical triggering element, which holds the closure element in the closed position. In some embodiments, the triggering element is preferably configured as a temperature-sensitive element of a sprinkler. For example, the triggering element can be designed as a glass ampoule filled with liquid, whereby the liquid within the glass ampoule heats up and expands in case of fire. This leads to a bursting of the glass ampoule, ie to a triggering of the triggering element.

In the case of this release, the closure element is no longer held in the closing position, but moves from the closed position to the open position. As a result, the fluid flow through the nozzle connection opening is released.

When the extinguishing fluid exits the nozzle connection opening, it reaches the alignment element. The alignment element preferably has one or more directional surfaces, which act on the extinguishing fluid with a predetermined directional characteristic. For this purpose, the extinguishing fluid emerging from the nozzle connection opening is preferably guided onto a surface which has a specific surface structure. The extinguishing fluid is directed by this surface structure in a certain direction and can be acted upon with a predetermined directional characteristic.

In one development, the alignment element is designed as an extinguishing fluid-carrying nozzle channel, which is set up to direct the extinguishing fluid to the plurality of nozzle outlet openings.

In some embodiments, the alignment element is designed in particular as a fluid-tight channel. In this embodiment, the nozzle outlet openings are preferably designed as openings in the channel. Again, the Düsenauslassöffnungen can be arranged again at the top and / or bottom and / or sides of the channel. The channel may in this case have an annular cross-section. Alternatively, the cross section may also be rectangular, square, triangular or the like. The geometry of the channel cross-section is preferably adapted to the requirements of the component to be protected. The fluid-tight channel is preferably connected via the nozzle connection opening with an extinguishing fluid supply, in particular with the extinguishing fluid supply line of the component. In the case of triggering the trigger element and a corresponding moving of the closure element from the closure to the open position, the fluid flow is released through the nozzle port and the quenching fluid enters the nozzle channel. The extinguishing fluid is led to the nozzle outlet openings via the nozzle channel and is discharged from the nozzle through them. This embodiment is particularly suitable in cases where the extinguishing fluid supply line of the component is under a comparatively low pressure.

In a further embodiment, the nozzle is arranged at or in the vicinity of a bottom side of the housing.

In some embodiments, the nozzle is preferably located at or near the bottom of the component or housing. Under the underside is in this case the side of the component, or the housing understood, which is directly opposite a bottom surface, above which the component is arranged. The component further has an upper surface which, starting from the bottom surface, lies further away from the latter. In a closed room, the top faces the ceiling.

The nozzle is preferably arranged on the underside of the housing - and thus on the underside of the component - or in the vicinity of the underside. This embodiment is based on the recognition that in an arrangement at the top of the housing this forms a kind of fluid shadow for the emerging from the nozzle extinguishing fluid. As a result, the quenching fluid can not be evenly distributed to the component. In particular, the fluid shadow prevents distribution of the extinguishing fluid to the underside of the component and to the area below the component that is closer to the bottom surface.

This is particularly problematic if this area is heated in the event of fire first. In some particularly unfavorable cases of fire, the fire occurs immediately under the component or in the immediate vicinity of the component. In these cases, the area below and in the lower part of the component requires particularly adequate cooling. By arranging the nozzle at or in the vicinity of the bottom of this cooling can be achieved. In this case, the nozzle is preferably equipped with an outlet characteristic which directs the extinguishing fluid to the underside and to the sides of the component. In this way, an efficiency of cooling - and thus a limitation of the temperature increase - can be achieved. It is also possible to use the component at least one nozzle, which is arranged at or in the vicinity of the underside of the housing, and at least one nozzle, which is arranged at or in the vicinity of the top of the housing, equip. As a result, the cooling can be further improved.

According to a further preferred embodiment, the fire protection system comprises a fire extinguishing system, in particular a sprinkler system, wherein the nozzle can be connected to the extinguishing fluid supply of the fire extinguishing system.

In one embodiment, the fire protection system has at least one fire extinguishing system. As mentioned in the introduction, fire-extinguishing systems are systems which are always ready for operation and serve to extinguish fires by means of an extinguishing fluid. Fire extinguishing systems can be formed in a variety of ways and use a variety of extinguishing fluids. By way of example, mention should be made here of water extinguishing systems in which the extinguishing fluid comprises water, powder extinguishing systems in which powder is used as the extinguishing agent, or gas extinguishing systems which use, for example, inert gases or carbon dioxide as extinguishing fluid. A fire extinguishing system according to the invention can be designed in particular as a sprinkler system. Sprinkler systems are a form of automatically functioning water extinguishing systems. They have a sprinkler pipe network that supplies a large number of sprinklers with the extinguishing fluid. Each of these sprinklers is sealed with a temperature-sensitive element, such as a glass ampule. Outside of a fire, the temperature-sensitive elements retain their shape and / or position and thus keep all the sprinklers closed, resulting in a constant pressure of the extinguishing fluid within the pipe network. In the event of a fire, the temperature-sensitive elements located near the source of the fire heat up and thus change their shape and / or position - the glass ampoules burst, for example - whereby extinguishing fluid can escape from the corresponding sprinkler or the corresponding sprinklers. This leakage of extinguishing fluid leads to a pressure drop in the pipe network. The pressure drop then leads to the opening of the above mentioned alarm valves - which accordingly have to keep their functionality during the fire - and optionally to activate further components such as pumps or similar. This, in turn, causes further extinguishing fluid to be introduced into the pipe network, through which the extinguishing fluid is passed at high pressure and then exits through all open sprinklers. As a result, the spread of the fire can be prevented or minimized. All fire extinguishing systems have in common that they have an extinguishing fluid supply to supply the fire extinguishing system with extinguishing fluid. It is preferred that the component of the fire protection system comprising the fire extinguishing system be supplied by the extinguishing fluid supply of the fire extinguishing system. This eliminates the need to provide an additional external extinguishing fluid supply to the nozzle. This has the advantage that, on the one hand, the production is simplified, since the component or the housing of the component only has to be equipped with an extinguishing fluid inlet and / or an extinguishing fluid connection for connection to the extinguishing fluid supply and then can be integrated directly into the system. The need to make an additional extinguishing fluid supply and other components and elements that ensure a reliable supply of the component with extinguishing fluid is bypassed here.

In a further preferred embodiment of the component, the nozzle is connected to a switching element which is arranged to close when a predetermined pressure threshold value is exceeded, the component being connected to an alarm element which is arranged to issue an alarm in response to the closing of the switching element ,

The embodiments described above provide a triggering of the nozzle and thus a cooling of the component in case of fire. It is preferred that the component, preferably the nozzle, also has an alarm function. For this purpose, the component for a fire protection system may further comprise a switching element, in particular a pressure switch, which is accommodated within the component, in particular within a fluid connection between the extinguishing fluid inlet and an extinguishing fluid outlet within the component. Alternatively or additionally, the switching element can also be accommodated within a channel which serves to extinguish the fluid supply to the component, or within a dedicated and / or external alarm line. The switching element is preferably set up so that it switches from a first switching position to a second switching position upon a change in the pressure acting on it-that is to say when the pressure within the fluid connection and / or the channel and / or the alarm line changes.

It is particularly preferred here that the switching element reacts to an exceeding of a predetermined pressure threshold value. Even more preferably, the switching element closes in response to the pressure threshold being exceeded. This causes the output of a A signal which is transmitted to an alarm element which triggers a corresponding alarm in response to this signal.

In the locked state, the fluid connection and / or the channel and / or the alarm line are in this case under atmospheric air pressure. If the water flows into the fluid connection and / or the channel and / or the alarm line by opening a blocking element and / or a closure element, a water pressure is established, ie a change in pressure takes place. The pressure threshold value for the triggering of the switch is corresponding thereto the characteristics of the fire protection system. Preferably, the switching element switches at a threshold value of 0.55 bar. Alternatively, the switching element may also be set up to be closed in normal operation and to open only when the pressure threshold value is exceeded. In this case, the opening of the switching element causes a signal that serves to trigger the alarm element.

The alarm element can in this case be arranged directly on the component. Alternatively or additionally, the fire protection system may also comprise a separate alarm element. The alarm element may in particular be designed to output an audible and / or visible signal.

In a further preferred embodiment, the component is embodied as an extinguishing fluid-carrying component for a fire protection system, in particular a fire extinguishing system, wherein the component comprises the extinguishing fluid inlet and also an extinguishing fluid outlet, which is fluid-conductively connected to the extinguishing fluid inlet. In a preferred development of this embodiment, the extinguishing fluid inlet is connected to the nozzle by a fluid channel extending within the component.

According to one embodiment, the component for the fire protection system is an extinguishing fluid-carrying component, ie a component through which the extinguishing fluid for the fire protection system is guided. For this purpose, the component has an extinguishing fluid inlet as described above, ie an inlet, such as an opening in the housing of the component, through which the extinguishing fluid can enter the component and which can be equipped with a seal and / or a connection piece to form a fluid-tight connection to ensure an extinguishing fluid supply. Further, the extinguishing fluid carrying components include an extinguishing fluid outlet fluidly connected to the extinguishing fluid inlet. The extinguishing fluid outlet is a further opening in the housing of the component arranged in the flow direction of the extinguishing fluid, through which the extinguishing fluid can leave the component again. The extinguishing fluid outlet can also be equipped with a seal and / or a connecting piece in order to ensure a fluid-tight connection to the extinguishing fluid supply of the fire protection system, in particular the sprinklers and / or extinguishing nozzles of a fire extinguishing or spark extinguishing system.

The extinguishing fluid inlet and the extinguishing fluid outlet are fluidly connected to one another. This fluid-conducting connection can in particular be provided by a main chamber running inside the component from the extinguishing-fluid inlet to the extinguishing-fluid outlet in the direction of flow of the extinguishing-fluid. Preferably, the main chamber has a barrier member which interrupts the connection between the extinguishing fluid inlet and the extinguishing fluid outlet in a blocking position, thus dividing the main chamber into a separate fluid inlet chamber on the side of the extinguishing fluid inlet and a separate fluid outlet chamber on the side of the extinguishing fluid outlet. In an unlocking position, the fluid inlet chamber and the fluid outlet chamber are fluid-conductively connected. In the blocking position, therefore, no extinguishing fluid can flow from the extinguishing fluid inlet to the extinguishing fluid outlet. In contrast, in the unlocked position, the extinguishing fluid can flow from the extinguishing fluid inlet to the extinguishing fluid outlet.

Extinguishing fluid-carrying components are used in particular in fire extinguishing systems, but also in spark extinguishing systems. As an example of such extinguishing fluid-carrying components, fire extinguishing system valves should be mentioned in this connection. Under fire extinguishing systems valves in the context of the invention, the genus is understood in particular both passive and active alarm valves for use in fire extinguishing systems, especially fire extinguishing systems with water-based extinguishing agents (for example, water, water with additives, etc.). The best-known examples of these alarm valves are wet and dry alarm valves and spray water valves.

In this case, a passive alarm valve is understood to mean a valve which automatically opens when the predetermined pressure differences between the extinguishing fluid inlet and the extinguishing fluid outlet are exceeded, that is, the blocking element is moved independently from the blocking position into the unlocking position. In this case, the alarm is usually triggered by the valve in response to detecting an opening state of the valve, for example by means disposed in an external alarm line switching element, in particular a pressure switch, which then controls an alarm element, such as an electrically operated alarm horn. Alternatively or additionally, the alarm may also be triggered by the control of the extinguishing agent flow to a hydraulically operated alarm element connected fluidly to the alarm valve, such as a water-operated alarm bell.

An active alarm valve is understood to be a valve which actively releases the fluid flow and triggers an alarm after an input of a corresponding signal from external fire detection means, such as the above-mentioned fire detectors, or as a function of external control interventions, by opening the blocking element.

If the nozzle is arranged on such an extinguishing fluid-carrying component, it is advantageous if the nozzle is supplied with extinguishing fluid directly via the extinguishing fluid inlet of the component. The nozzle is thus made connectable to the extinguishing fluid supply of the fire protection system. Such a connection can in this case be realized, in particular, by a fluid feed line from the extinguishing fluid inlet to the nozzle.

Preferably, the nozzle may be supplied by a fluid channel extending inside the component which connects the extinguishing fluid inlet of the component and the nozzle in a fluid-conducting connection. In this case, it is particularly preferred that the nozzle is arranged such that the fluid channel can be designed as a branch from the main chamber, which fluidly connects the extinguishing fluid inlet to the extinguishing fluid outlet of the component. The nozzle may in this case preferably be arranged on the same surface of the component as the extinguishing fluid outlet. In this case, the fluid channel may be implemented as an L-shaped channel within the component. The advantage of this design is that no additional supply of the nozzle with extinguishing fluid and no external connecting pieces for supplying the nozzle are required here, but the nozzle can be supplied with the extinguishing fluid passed through the component directly via a fluid connection running within the component. This can save manufacturing costs and reduce the weight of the component. In a preferred embodiment, the fluid channel may be configured to fluidly direct the nozzle to the fluid inlet chamber and the extinguishing fluid inlet and to the fluid outlet chamber and the extinguishing fluid outlet combines. In this case, therefore, the extinguishing fluid via the fluid channel is not only fed to the nozzle, but can also be directed away from it.

In the event that the component is an extinguishing fluid-carrying component, there is also the further advantage that by guiding the extinguishing fluid through the component, the latter not only by the discharge of the extinguishing fluid through the nozzles and in the vicinity of the component is cooled, but also from the inside through the flowing through them extinguishing fluid. This achieves an improved cooling effect.

In a further preferred development of the embodiment, the fluid channel comprises at least one valve element.

Advantageously, the fluid channel is further protected by a valve element. The valve element can preferably be arranged in a section which connects the fluid inlet chamber of the component with the fluid channel or with the fluid-conducting connection to the nozzle. In particular, the valve element can be arranged at the inlet of the fluid channel. In this embodiment, the valve element can preferably be designed as a check valve, which is set up so that the extinguishing fluid can flow from the fluid inlet chamber into the fluid channel, but can no longer leave it in the direction of the fluid inlet chamber. The check valve thus preferably serves to open the transition from the fluid inlet chamber to the fluid channel in the direction of the nozzle and to close it in the opposite direction.

By this embodiment, it can be ensured that the fluid channel is always filled with extinguishing fluid and so the nozzle can be safely supplied with extinguishing fluid in case of fire.

Alternatively or additionally, however, the or an additional valve element can also be arranged at another point of the fluid channel. If the fluid channel has a feed line to the fluid outlet chamber, a valve element can also be arranged in the connection section with the fluid outlet chamber. In this case, the valve element is preferably arranged to block the connection between the fluid channel and the fluid outlet chamber when the blocking element is in a blocking position and opens the connection when the blocking element moves into the unlocking position. In this way it can be ensured that the fluid channel for supplying the nozzle is part of the extinguishing fluid circuit represents when the blocking element is moved to the unlocked position and the extinguishing fluid supply is opened.

In an alternative embodiment, the component is embodied as a non-extinguishing fluid-carrying component, wherein the extinguishing fluid inlet, which is fluid-conductively connected to the nozzle, can be connected to the extinguishing fluid supply via an external connecting element. In a preferred development of this embodiment, the extinguishing fluid inlet has a connection element, wherein the connection element can be connected to the external connection element.

In a further embodiment of the invention, the component for the fire protection system is a component through which no extinguishing fluid is passed. Such components may in particular be electronic components, such as control cabinets, gearboxes, measuring devices, pumps or fire detectors, which must continue to function in the event of a fire. These components are advantageously designed as disguised components. This means that the housing is used to cover the corresponding internal electronic components. According to the invention, the housing must therefore be able to protect in particular the interior of the components from the penetration of the extinguishing fluid. It is therefore preferred that the components are at least splash-proof, in particular protected against spraying water on all sides with elevated pressure. In this case, the housing is thus preferably manufactured at least in accordance with the IP protection class IP54. In this case, since electronic components are located inside the component, it is preferable that the quenching fluid is not conducted to the nozzle through the inside of the component, or the inside of the housing. Rather, the fluid supply should be made from the extinguishing fluid supply to the nozzle outside the housing, in particular along the housing. This extinguishing fluid supply can be designed separately and serve only to supply the nozzle. Alternatively, the extinguishing fluid supply to the nozzle can also be effected via the extinguishing fluid supply of the fire protection system, if present.

According to the invention, an extinguishing fluid inlet is provided for this purpose, through which the extinguishing fluid can not get into the interior of the component in which the electronic components are located. In one embodiment, the housing may, in particular, include a dedicated nozzle port area that is spatially separated from the remainder of the component and includes the quench fluid inlet and a corresponding fluid channel. The extinguishing The drain is then connected to the extinguishing fluid supply by means of an external connection element. Such a connecting element can be configured for example in the form of a tube or a hose. It should be noted that the material from which the pipe or hose is made should be as fire-resistant as possible, so that a supply of the nozzle in case of fire can be ensured.

It is preferred that the connecting element and the extinguishing fluid inlet are fluid-tightly connectable to each other. For this purpose, the extinguishing fluid inlet to a connection element, which is preferably designed as a seal. Alternatively or additionally, the connecting element may also have a seal. By sealing the connection between the connecting element and the extinguishing fluid inlet, it is possible to prevent extinguishing fluid from the extinguishing fluid supply from reaching the component outside of the fire.

The nozzle is supplied by supplying the extinguishing fluid through the connecting element into the extinguishing fluid inlet. The quenching fluid passes through the quench fluid inlet and is directed to the nozzle via the fluid channel. For this purpose, the nozzle is preferably arranged at the nozzle connection region. It is advantageous in this case if the nozzle connection region and / or the nozzle also have one or more seals. In this way it can be ensured that the extinguishing fluid escapes from the opening of the nozzle in the event of fire at high pressure and can not previously escape through the connection between nozzle and nozzle connection area. The invention has been described above with reference to a first aspect with reference to the component for the fire protection system itself.

However, in a further aspect, the invention also relates to a nozzle for a component of the aforementioned type, comprising: a plurality of nozzle outlet openings, at least one triggering device and an alignment element, wherein the plurality of nozzle outlet openings are arranged in a geometrically predetermined arrangement on the alignment element , In a further development of this embodiment, the alignment element is embodied as an extinguishing-fluid-carrying nozzle channel, which is set up to direct the extinguishing fluid to the plurality of nozzle outlet openings.

The nozzle according to the invention makes use of the advantages and preferred embodiments of the component according to the invention. The preferred embodiments and developments of the component are therefore at the same time preferred embodiments and developments of the nozzle. In a still further aspect, the invention relates to a fire protection system, in particular a fire extinguishing system, which comprises at least one component according to the embodiments set out above.

In a further aspect, the invention relates to a method for producing a component for a fire protection system. The method comprises the steps of disposing at least one nozzle for applying quenching fluid to the component to a housing or in the vicinity of a housing and connecting the nozzle to an extinguishing fluid supply. In a preferred embodiment, the method further comprises a molding of the housing - completely or partially - from a material having a melting temperature of less than 800 ° C. In a development, the method further comprises providing, within the component, an extinguishing fluid inlet and an extinguishing fluid outlet, which is fluid-conductively connected to the extinguishing fluid inlet, and connecting the extinguishing fluid inlet to the nozzle through a fluid channel extending within the component.

In accordance with this aspect, the quench fluid is used to maintain the housing of an extinguishing fluid-carrying component and / or the quench fluid-carrying component as a whole below the melting temperature. Thus, cooling at a temperature below the melting temperature is understood to mean that the quenching fluid should maintain the temperature of the housing and / or the component at a value below the melting temperature value.

More particularly, in one aspect, the invention relates to a method for protecting an extinguishing fluid carrying component, in particular a valve, such as an alarm valve, comprising an extinguishing fluid inlet and an extinguishing fluid outlet, the extinguishing fluid inlet and the extinguishing fluid outlet forming a fluid passage within the component, the method comprising the steps comprising: arranging a nozzle at or in the vicinity of a housing of the component and supplying the nozzle with an extinguishing fluid from the fluid channel.

Embodiment.

1 shows a component 1 for a fire protection system 100 according to a first, preferred embodiment of the invention.

In this embodiment, the component 1 is designed as an extinguishing fluid-carrying component in the form of a wet alarm valve. The component 1 comprises a nozzle 10, a housing 1 1, an inlet-side connecting piece 1 13 with the extinguishing fluid inlet 1 1 1 and an outlet-side connecting piece 1 14 with the extinguishing fluid outlet 1 12. The housing 1 1 and / or the inlet-side connecting piece 1 13 and / or the outlet-side connecting piece 1 14 are preferably at least partially made of a light metal or a plastic.

The nozzle 10 is designed as a stand-on sprinkler arranged on the housing 11 and is supplied with extinguishing fluid through a fluid channel (not shown in FIG. 1) running inside the component 1. By arranging the nozzle 10 on the housing 1 1 ensures that the emerging in case of fire from the nozzle 10 extinguishing fluid can get directly to the housing 1 1 and this protects accordingly.

The extinguishing fluid-carrying component 1 is connected through the inlet-side connecting piece 1 13 to an extinguishing fluid supply of the fire protection system, in particular a fire extinguishing system. The inlet-side connecting piece 1 13 comprises an extinguishing fluid inlet 1 1 1, through which the extinguishing fluid enters the interior of the component 1.

The extinguishing fluid-carrying component 1 is further connected by an outlet-side connecting piece 1 14 to the extinguishing fluid supply to the fire protection system and forms thus an element within the extinguishing fluid supply. The outlet-side connection connection piece 114 comprises an extinguishing-fluid outlet 1 12, through which the extinguishing fluid can leave the interior of the component 1 again, in order to reach further components of the fire protection system, such as, for example, the sprinkler heads or extinguishing nozzles. In the event of a fire, the ambient temperature of the nozzle 10 heats up. In this embodiment, in which the nozzle 10 is designed as a standing sprinkler, this heating destroys the temperature-sensitive element and the nozzle 10 is triggered and applies extinguishing fluid to the component 1 in order to protect it.

FIG. 2 shows the extinguishing fluid-carrying component 1 from FIG. 1 in a schematic, spatial cross-sectional view.

The extinguishing fluid passes through the extinguishing fluid inlet 11 1 in the inlet-side connecting piece 1 13 of the extinguishing fluid supply of the fire protection system in the interior of the extinguishing fluid leading component 1. To make the connection of the inlet side connecting piece with the extinguishing fluid supply of the fire protection system fluid-tight, comprising the inlet side connecting piece 113 a connection and Sealing element 115, which connects a supply line of the extinguishing fluid supply with the inlet-side connecting piece 113.

Inside the component runs a main chamber 12, which is divided by the blocking element 116 into a fluid inlet chamber 121 and a fluid outlet chamber 122. A fluid channel 117 extends from the fluid inlet chamber 121 of the main chamber 12 in the direction of the nozzle 10 and thus connects the nozzle 10 with the extinguishing fluid supply of the fire protection system.

In the embodiment of FIG. 2, the fluid channel 117 comprises a feed line to the nozzle and also a discharge in the direction of the fluid exit chamber 122, on which a valve element 118 is arranged. In the fluid inlet chamber 121 there is a permanent water pressure (1 to 21 bar) and thus also in the fluid channel 117 and on the nozzle 10.

The fluid channel 1 17 acts as a bypass line, which is able to compensate for small pressure differences of about 15 l / min. As soon as the flow rate through the fluid channel 117 exceeds a flow rate of approximately 15 l / min, ie if the flow rate is higher than 15 l / min, the blocking element opens and the alarm is triggered. The valve element 118 is designed here as a check valve, which prevents the backflow of possible contaminated water, dead and stale water, from the sprinkler piping network and at the same time keeping the water within the sprinkler piping network under pressure.

If the blocking element 16 moves into the unlocking position, the extinguishing fluid can flow through the main chamber 12 from the extinguishing fluid inlet 11 into the direction of the extinguishing fluid outlet 11 and then through the fire protection system. For this purpose, the component 1 is integrated by the outlet-side connecting piece 1 14 in the extinguishing fluid supply. Also, the outlet-side connecting piece 1 14 preferably has a sealing element such as a sealing ring in order to produce a fluid-tight connection with the extinguishing fluid supply. FIG. 3 shows a component 2 for a fire protection system according to a further preferred embodiment.

Component 2 of FIG. 3 is a non-extinguishing fluid-carrying component in the form of a control cabinet for electronics. The non-extinguishing fluid-carrying component 2 comprises a nozzle 20 designed as a standing sprayer for self-protection of the component 2 and a housing 21.

The housing 21 includes a nozzle port area 222 for locating the nozzle on the housing. The nozzle connection region 222 comprises an extinguishing fluid inlet 221, through which the extinguishing fluid passes into a fluid inlet chamber (not shown in FIG. 3) within the nozzle connection region 222 and from there to the nozzle 20. The nozzle connection region 222 is connected in a fluid-tight manner to an external connection element 225 via a connection element 223, which is preferably designed as a seal. The housing 21 and the nozzle connection area 222 are preferably made of a light metal or a plastic. The housing 21 should also be manufactured splash-proof. The external connection element 225 is preferably designed as a tube or hose and serves to supply extinguishing fluid from an extinguishing fluid supply. This extinguishing fluid supply can be either a dedicated extinguishing fluid supply or an extinguishing fluid supply to a fire protection system.

In the event of fire, the area around the nozzle 20 heats up and triggers the nozzle 20. In this case, extinguishing fluid escapes from the nozzle 20 and is applied to the component 20 in order to protect it during the fire. FIG. 4 shows an extinguishing fluid-carrying component T in a further preferred embodiment. The component T according to FIG. 4 largely corresponds to the component 1 of FIG. 1, that is to say the component T is also configured in the form of a wet alarm valve. As already described in connection with FIG. 1, the component 1 'comprises a nozzle 10, a housing 11, an inlet-side connecting piece 113 with the extinguishing-fluid inlet 111 and an outlet-side connecting piece 114 with the extinguishing-fluid outlet 112, the housing 11 and / or the inlet-side connecting piece 113 and / or the outlet-side connecting piece 114 are preferably at least partially made of a light metal or a plastic. Unlike in the embodiment of FIG. 1, in the embodiment according to FIG. 4, the nozzle 10 is not designed as a standing-type sprinkler arranged on the upper side of the housing 11, but is arranged on the underside of the housing 11. The nozzle 10 is - in analogy to the embodiment of Figure 1 - supplied by a running inside the component T fluid channel with extinguishing fluid. The advantage of this embodiment, in which the nozzle 10 is arranged on the underside of the housing 11, is here to be seen in that - unlike in some embodiments, in which the nozzle 10 is arranged at the top of the housing 1 1 - in the present If there is no fluid shadow for the extinguishing fluid through the housing 11 on its underside, which could cause the extinguishing fluid can not be distributed anywhere along the housing 11 and, at the locations where the extinguishing fluid does not arrive, to an increase in temperature of the housing 11 (and the other parts of the component 1) can lead. By arranging at the bottom of this temperature rise can therefore be limited.

In a further preferred embodiment, the component T can also be changed so that it has both at least one nozzle 10 on the upper side and at least one nozzle 10 on the lower side. This allows even better cooling, since the nozzle 10, which is arranged at the top, the component T from above cools and the nozzle 10, which is arranged at the bottom, the component T from below cools. FIG. 5 shows a modification of the preferred embodiment according to FIG. 4. In order to avoid repetition, we will not deal with the following details of component 1 ", which correspond to those of component 1 and T according to FIGS. 1 and 4, but the differences to show the previous figures. In the embodiment according to FIG. 5, the at least one nozzle 10 is not arranged on the housing 1 1 itself, but in the vicinity of the housing 1 1. In the specific embodiment of FIG. 5, the nozzle 10 is arranged in the vicinity of the underside of the housing 11. In other embodiments, however, the nozzle 10 can also be arranged in the vicinity of the top of the housing 1 1 and / or in the vicinity of the housing center of the housing 1 1 from the top and bottom or at other positions. Further possibilities of arranging are conceivable. It is also possible to arrange a plurality of nozzles 10 in the vicinity of the housing 1 1 in this way.

In the embodiment of Fig. 5, the nozzle 10 is connected to a jet extinguishing fluid supply 19, which serves to supply the nozzle 10 with extinguishing fluid. In this case, the nozzle extinguishing fluid supply 19 can preferably be designed as part of the extinguishing fluid supply of the fire protection system. Thus, the nozzle 10 is supplied via the nozzle extinguishing fluid supply 1 19 with extinguishing fluid, which is derived directly from the extinguishing fluid supply to the fire protection system. In this way it can be ensured that always sufficient extinguishing fluid is available. In other embodiments, the jet extinguishing fluid supply 1 19 may also be configured as an additional jet extinguishing fluid supply, which is independent of the extinguishing fluid supply of the fire protection system.

By providing a nozzle 10 in the vicinity of the housing 1 1, in particular a better distribution of the extinguishing fluid for cooling the component 1 "can be achieved. In some embodiments, the nozzle 10 in the vicinity of the housing 1 1 with one or more of the housing 1 1 arranged nozzles 10 are combined.

FIG. 6 schematically shows an exploded view of a nozzle 3 according to one aspect of the present invention. The nozzle 3 includes a plurality of nozzle outlet ports 301, an aligning element 302 and two triggering devices 30. The nozzle 3 is disposed on an extinguishing fluid supply line 4 of a component. The extinguishing fluid supply line 4 of the component is for this purpose at least one nozzle connection opening 41, the principle of which will be explained in more detail in connection with FIG.

In the specific embodiment of FIG. 6, the alignment element 302 is composed of two individual elements 302a and 302b, which are fluid-tightly connected by means of connecting elements 302c, which are designed as screws in FIG. The

Nozzle outlet openings 301 are arranged in the embodiment of FIG. 6 at the top of the alignment element 302 (and thus at the top of the nozzle 3). Alternatively or additionally, however, the nozzle outlet openings 301 can also be arranged on the underside of the alignment element 302. The alignment element 302 also has a plurality of openings 303, of which only one is shown in FIG. 6. These openings 303 serve to receive the triggering devices 30. In this case, the triggering device 30 is inserted into the opening 303 and arranged in the opening 303 such that the triggering device 30 closes the opening 303 in a fluid-tight manner.

This principle is shown once more schematically in FIG. 7, which shows a cross-sectional view of the nozzle according to the embodiment of FIG. 6. In FIG. 7, the triggering device 30 is arranged in the opening 303 and the nozzle connection opening 41. Here, the triggering device 30 is designed such that the opening 303 terminates in a fluid-tight manner with the triggering device 30. Furthermore, the nozzle connection opening 41 with the combination of alignment element 302 and triggering device 30 also terminates in a fluid-tight manner.

As FIGS. 6 and 7 furthermore show, the triggering devices comprise a triggering element 31 and a closure element 32. In the specific embodiment, the triggering element 31 is designed as a thermal triggering element. As can be seen in FIG. 7, the triggering element 31 holds the closure element 32 in a closure position 33, in which the closure element 32 closes the nozzle connection opening 41 in a fluid-tight manner and thus prevents supply of the nozzle 3 with extinguishing fluid from the extinguishing fluid supply line 4. When the trigger element 31 triggers, that is bursts or otherwise moved out of position, the closure element 32 is no longer held in the closed position, but moves into the open position 34. Thereby, the fluid flow through the nozzle port 41 is released. The extinguishing fluid thus passes through the nozzle connection opening 41 into the alignment element 302 and is distributed in this. When the alignment member 302 is filled with quenching fluid, the quenching fluid then exits through the nozzle outlet apertures 301 at the top of the alignment member 302.

The nozzle 3 according to the embodiment of FIGS. 6 and 7 is particularly suitable for being arranged at or in the vicinity of an underside of a component. In this case, the nozzle 3 can be arranged in particular on the extinguishing fluid supply line 4, which-in the case of an extinguishing fluid-carrying component-supplies the component with extinguishing fluid. The extinguishing fluid exiting from the nozzle outlet openings 301 is then directed towards the bottom of the component, thus cooling both the housing 11 and the component itself, as well as the vicinity of the component. This makes it possible to make the housing 11 entirely or partially of a material having a lower melting temperature than materials according to the prior art. FIG. 8 schematically shows a nozzle 3 'according to a further preferred embodiment comprising a plurality of nozzle outlet openings 301 and two triggering devices 30. The mode of operation of the nozzle outlet openings 301 corresponds to the mode of operation as explained in connection with FIGS. 6 and 7. The principle of the triggering device 30 is largely analogous to the operation as explained in connection with Figures 6 and 7. Also in this embodiment, the shutter member 32 is held by the trigger member 31 in a closed position in which the flow of fluid from the extinguishing fluid supply pipe 4 through the nozzle port holes 41 through the shutter member 32 is inhibited. In the embodiment of FIG. 8, however, the triggering of the triggering element 31, which can again be embodied as a thermal triggering element, causes the closure element 32 not to be moved into an open position. Instead, the shutter member 32 is released and then "drops" out of the shutter position to release the nozzle port 41. Preferably, the triggering device 30 is arranged on the aligning element 302 'or connected thereto, that the triggering device 30, and in particular the triggering element 31, so far unprotected that there are possible temperature changes in the area around the nozzle 3', ie on the housing 11 or in the vicinity the housing 11 of the component is directly exposed. As a result, a rapid triggering of the nozzle 3 'can be ensured.

The alignment member 302 'also consists of two individual members 302'a and 302'b interconnected by two connectors 302'c, which in the specific embodiment are designed as screws. The decisive difference from the embodiment of FIGS. 6 and 7 lies in the embodiment of FIG. 8, in particular in that the aligning element 302 'is not designed as a fluid-tight ring, but rather as a disk which is opened upwards and downwards. This embodiment of the nozzle 3 'is particularly suitable in cases where the extinguishing fluid is led under high pressure in the extinguishing fluid supply line 4 and accordingly with high pressure from the nozzle connection opening 41 penetrates when it is opened. The openings of the disc serve as nozzle outlet openings 301 of the nozzle 3 ', which comprises the alignment element 302'. The nozzle 3 'thus has nozzle outlet openings 301 on the top side and the bottom side. However, the alignment element 302 'of the nozzle 3' can also be configured such that the nozzle 3 'has nozzle outlet openings 301 only at the top side or only at the bottom side. FIG. 9 shows the nozzle 3 'in a cross-sectional view. As FIG. 9 shows, the alignment element 302' comprises a plurality of straightening surfaces 301a arranged inside the nozzle outlet openings 301 on the outer ring of the disk in the direction of the extinguishing fluid supply line 4. These aiming surfaces 301a serve, after triggering of the nozzle 3 'by the triggering device 30, to align the extinguishing fluid guided from the extinguishing fluid supply line 4 into the nozzle along the nozzle connection opening 41 along a specific directional characteristic so as to obtain an optimum distribution of the extinguishing fluid on the component 10 enable.

For this purpose, the straightening surfaces 301a can be formed in different ways. In the embodiment of Figure 9, the straightening surfaces 301a are rounded, for example. In other embodiments, however, the straightening surfaces 301a may also be formed as smooth surfaces, as wavy surfaces, in an angular or in another geometric design. The size and surface shape of the straightening surfaces 301a should here be selected with regard to the component to be protected, the position of the nozzle 3 'in the ratio of the component, as well as with regard to pressure and composition of the extinguishing fluid.

In the embodiments of FIGS. 6 to 9, the nozzle 3, 3 'has been arranged on the extinguishing fluid supply line 4 of a component such as component 1, V and 1 ". This arrangement can preferably take place along the fluid direction in front of the component 1, V, 1 "-thus on the underside of the component 1, V, 1" -or in the fluid direction according to the component 1, V, 1 "-thus at the top of the component 1, V, 1 Arranging on the extinguishing fluid supply line 4 means that the nozzle 3, 3 'is arranged at some distance from the component 1, V, 1 "in its vicinity.

Alternatively or additionally, however, the nozzle 3, 3 'can also be arranged directly on the component. Such a component 1 '", which is suitable for enabling a connection of a nozzle 3, 3', is shown schematically in FIG. The component 1 '"of FIG. 10 corresponds largely to the components 1, V, 1" as described in more detail in connection with Figures 1, 2, 4 and 5. To avoid repetition, we refer in this respect to the description of these figures.

Unlike the components 1, 1 'and 1 "of Figures 1, 2, 4 and 5, the component 1 of Figure 10 is suitable for the connection of a nozzle 3, 3'. For this purpose, the component 1 '"comprises at least one nozzle connection opening 41. This at least one nozzle connection opening 41 is preferably arranged on the inlet-side connecting piece 1 13' and / or on the outlet-side connecting piece 1 14 '. The nozzle 3, 3 'can then be either at Einlass- side connecting piece 1 13 'or at the outlet side connecting piece 1 14' are arranged and as described in connection with Figures 6 to 9. It should be noted that the design of the nozzle 3, 3 'according to the embodiment of Figures 6 and 7 or according to the embodiment of Figures 8 and 9 may be configured. It is also possible to use a combination of both embodiments or a different embodiment. It is important at this point to adapt the arrangement of the nozzle 3, 3 'and the geometric arrangement of the nozzle outlet openings 301 and the triggering devices 30 to the respective conditions of the individual components.
