Description

La présente invention concerne un corps de vanne et un arrangement de déclenchement d'au moins un corps de vanne selon le préambule des revendications 1 et 10.The present invention relates to a valve body and a trigger arrangement of at least one valve body according to the preamble of claims 1 and 10.

Un arrangement de déclenchement est connu de DE3314905A1 . Un dispositif d'éjection connu d'un agent (liquide et/ou gaz) d'extinction de feu ou de refroidissement est représenté en figure 1 et comprend au moins une bouteille (Bol, Bo2, ...) sous haute pression (par exemple 300 bar) contenant le dit agent, ladite bouteille étant couplée à une vanne de déclenchement afin d'expulser l'agent sous une pression pouvant être régulée (par exemple sous une pression de sortie de 40bar). Selon la figure 1, la vanne de déclenchement comprend elle-même un corps de vanne (Co1, Co2,...) généralement vissé en partie supérieure de la bouteille, le dit corps de vanne (Co1, Co2,...) comprenant :

  • une vanne de décharge (V1, V2,...) de l'agent comprenant un gaz et/ou un liquide, la dite vanne déchargeant par un canal de sortie (Cs1, Cs2,...) pour la décharge en pression à une sortie de décharge (Sd1, Sd2,...) de corps de vanne ;
  • une entrée de déclenchement de vanne (Ed1, Ed2,...) reliée par un canal de déclenchement (Cd1, Cd2,...) à un dispositif d'amorçage de décharge de la vanne (V1, V2,...) ;
  • une sortie en pression (Sb1, Sb2,...) couplée par un canal de dérivation (D1, D2,...) au canal de sortie (Cs1, Cs2,...).
A triggering arrangement is known to DE3314905A1 . A known ejection device of an agent (liquid and / or gas) for extinguishing fire or cooling is represented in FIG. figure 1 and comprises at least one bottle (Bol, Bo2, ...) under high pressure (for example 300 bar) containing said agent, said bottle being coupled to a trigger valve in order to expel the agent under a pressure that can be regulated (for example at an outlet pressure of 40bar). According to figure 1 , the tripping valve itself comprises a valve body (Co1, Co2, ...) generally screwed to the upper part of the bottle, the said valve body (Co1, Co2, ...) comprising:
  • a discharge valve (V1, V2, ...) of the agent comprising a gas and / or a liquid, said valve discharging through an outlet channel (Cs1, Cs2, ...) for the pressure discharge at a discharge outlet (Sd1, Sd2, ...) of the valve body;
  • a valve triggering input (Ed1, Ed2, ...) connected by a triggering channel (Cd1, Cd2, ...) to a discharging device for discharging the valve (V1, V2, ...) ;
  • a pressure output (Sb1, Sb2, ...) coupled by a bypass channel (D1, D2, ...) to the output channel (Cs1, Cs2, ...).

Sur cette base de dispositif d'éjection « bouteille/corps de vanne (Bo1, Co1)», la figure 1 représente un arrangement de déclenchement de plusieurs (ici 4) dispositifs dont les sorties de décharge (Sd1, Sd2, Sd3, Sd4) sont couplées à des canaux de distribution (Out1, Out2, Ou3, Out4) convergeant vers une tuyauterie (Out) d'éjection de l'agent. Les canaux de distribution peuvent prévoir des clapets anti-retour (Car_d1, Car_d2, Car_d3, Car_d4) permettant notamment de ne pas perturber les profils de décharge de chacun des dispositifs d'éjection et leurs corps de vanne respectifs destinés à être déclenchés en série.On this basis of ejection device "bottle / valve body (Bo1, Co1)", the figure 1 represents a triggering arrangement of several (here 4) devices whose discharge outputs (Sd1, Sd2, Sd3, Sd4) are coupled to distribution channels (Out1, Out2, Ou3, Out4) converging to a pipe (Out) d ejection of the agent. The channels of distribution may provide check valves (Car_d1, Car_d2, Car_d3, Car_d4) in particular not to disturb the discharge profiles of each of the ejection devices and their respective valve body to be triggered in series.

Généralement, le premier dispositif d'éjection comprenant le premier corps de vanne (Co1) est dénommé « maitre », car son entrée de déclenchement de vanne (Ed1) est couplée à un actionneur tel qu'un solénoïde (So1) ou un générateur de pression/gaz en tant que dispositif d'amorçage de décharge de la vanne (V1). Alternativement, le dispositif d'amorçage peut être conçu différemment afin de déclencher une ouverture de la vanne (V1), par exemple au moyen d'un système pneumatique, pyrotechnique, et/ou mécanique aboutissant à mettre la vanne (V1) en ouverture de décharge
Ensuite, le deuxième dispositif d'éjection comprenant le deuxième corps de vanne (Co2) est dénommé « esclave », car son entrée de déclenchement de vanne (Ed2 ou Ed2') est couplée à la sortie en pression (Sb1) du premier dispositif « maitre ». En d'autres termes et grâce à la dérivation (D1) du premier dispositif « maitre », le déclenchement du deuxième dispositif « esclave » (en aval) est activé par une sortie dérivée et prélevée sur la décharge du premier dispositif « maitre » (en amont). Ainsi, le déclenchement de la deuxième vanne (V2) est généré en pression au moyen d'une entrée (Ed2') du deuxième corps de vanne (Co2) complémentairement à l'entrée de déclenchement (Ed2), ce dernier étant usuellement prévue pour un système autonome de génération de gaz/pression tel que le solénoïde (So1), ladite entrée de bossage (Ed2) étant reliée par le canal de déclenchement (Cd2) et assurant le rôle du dispositif d'amorçage « esclave » de décharge de la deuxième vanne (V2). L'entrée de déclenchement (Ed2) usuellement prévue est ainsi condamnée de manière étanche par un bouchon fileté.Generally, the first ejection device comprising the first valve body (Co1) is called "master" because its valve trigger input (Ed1) is coupled to an actuator such as a solenoid (So1) or a generator. pressure / gas as the discharge device of the valve (V1). Alternatively, the priming device can be designed differently to trigger an opening of the valve (V1), for example by means of a pneumatic, pyrotechnic and / or mechanical system resulting in setting the valve (V1) to open. discharge
Then, the second ejection device comprising the second valve body (Co2) is called a "slave" because its valve triggering input (Ed2 or Ed2 ') is coupled to the pressure output (Sb1) of the first device " master ". In other words and thanks to the derivation (D1) of the first device "master", the triggering of the second device "slave" (downstream) is activated by a derivative output and taken on the discharge of the first device "master" ( upstream). Thus, the tripping of the second valve (V2) is generated in pressure by means of an inlet (Ed2 ') of the second valve body (Co2) in addition to the tripping input (Ed2), the latter being usually provided for an autonomous gas / pressure generating system such as the solenoid (So1), said boss input (Ed2) being connected by the trigger channel (Cd2) and providing the role of the "slave" discharge device for discharging the second valve (V2). The triggering input (Ed2) usually provided is thus sealed in a sealed manner by a threaded plug.

Enfin, à l'inverse du premier dispositif d'éjection « maitre », les deuxième, troisième et quatrième dispositifs successivement « esclaves » présentent un obturateur en pression (bouchon, capot, ...) sur toutes leurs sorties (Sb2, Sb3, Sb4) usuellement couplées respectivement par un canal de dérivation (D2, D3, D4) à leur canal de sortie (Cs2, Cs3, Cs4). En effet, seule le premier dispositif d'éjection « maitre » génère par sa sortie « dérivée » (Sb1) l'amorçage successif en pression des vannes « esclaves » (V2, V3, V4) couplées en série par leur entrées et sorties de bossage (Ed2', Sb2', Ed3', Sb3', Ed4') sous forme d'un canal unique de distribution de pression de déclenchement des dites vannes (V2, V3, V4), ledit canal de distribution de pression de déclenchement étant uniquement mis sous pression par la sortie en décharge du premier dispositif « maitre ».Finally, unlike the first ejection device "master", the second, third and fourth devices successively "slaves" have a shutter pressure (cap, hood, ...) on all their outputs (Sb2, Sb3, Sb4) usually coupled respectively by a bypass channel (D2, D3, D4) to their output channel (Cs2, Cs3, Cs4). Indeed, only the first "master" ejection device generates by its "derivative" output (Sb1) the successive priming in pressure of the "slave" valves (V2, V3, V4) coupled in series by their inputs and outputs of boss (Ed2 ', Sb2', Ed3 ', Sb3', Ed4 ') in the form of a single trigger pressure distribution channel of said valves (V2, V3, V4), said trigger pressure distribution channel being only pressurized by the discharge output of the first device "master".

Un tel arrangement à N corps de vannes couplés en série par un canal de déclenchement présente plusieurs inconvénients :

  • Les corps de vannes (Co1, Co2, ..., CoN) étant généralement réalisés sous une seule géométrie qu'ils soient associés à un dispositif d'éjection « maitre ou esclave », ils requièrent deux profils différents d'entrées spécifiques de déclenchement alternatif (Edi, Edi') (0<i<N+1), ainsi que trois profils de sorties en pression (Sdi, Sbi, Sbi'). Le nombre de ces entrées et sorties compliquent la conception des corps de vanne et la rende ainsi plus complexe et coûteuse
  • Les corps de vannes (Co1, Co2, ..., CoN) nécessitent aussi de prévoir un fort grand nombre de raccords ou bouchons, capuchons ou autres obturateurs afin de permettre le couplage ou le verrouillage en série du canal de distribution de pression de déclenchement des dites vannes (Vi) : par exemple sur la figure, le premier corps de vanne (Co1) dit « maitre » prévoit deux obturateurs sur son entrée (Ed1') et sortie (Sb1') de bossage pour condamner un déclenchement de type « esclave » ; le deuxième corps de vanne (Co2) de type « esclave » prévoit deux obturateurs sur son entrée (Ed2) et sa sortie (Sb2) de bossage pour ne permettre qu'un déclenchement de type « esclave » pour le troisième corps de vanne (Co3) ; le troisième corps de vanne (Co3) de type « esclave » prévoit deux obturateurs sur son entrée (Ed3) et sa sortie (Sb3) de bossage pour ne permettre qu'un déclenchement de type « esclave » pour le quatrième et dernier corps de vanne (Co4) ; enfin, le dernier et quatrième corps de vanne (Co4) de type « esclave » prévoit trois obturateurs sur son entrée (Ed4) et ses deux sorties (Sb4, Sb4') de bossage pour finaliser le déclenchement du quatrième dispositif de type « esclave ». Outre ce nombre élevé de raccords et obturateurs/capuchons, ceux-ci requièrent aussi d'être installés sans erreur et d'être maintenus/contrôlés, ce qui implique un effort considérable pour l'installation et la maintenance de système étendu. Inévitablement, le risque de fuite potentielle est proportionnel au nombre de ces composants de raccord ou d'obturation.
  • Un arrangement comprenant des dispositifs d'éjection en série selon la figure 1 prévoit un dispositif « maitre » en amont étant le déclencheur des autres dispositifs « esclaves » disposés en aval sous un accouplage en série. Toutefois, en raison d'un risque que le solénoïde (Sol) ou/et la vanne (V1) du dispositif « maitre » présente un disfonctionnement ou une panne de manière accidentelle, il est prévu selon la figure 3, un dispositif d'amorçage redondant par mesure de protection, par exemple en disposant un nouveau solénoïde sur le deuxième corps de vanne, ici (Co2) en figure 3, ou dans le cas de la figure 1, sur l'entrée de déclenchement (Ed2). Il s'avère de plus pour des raisons de performance que l'arrangement selon la figure 1, dans le cas où le nombre de bouteilles N est élevé, il soit nécessaire d'avoir une redondance intermédiaire de dispositifs de déclenchement mécanique ou par la pression, tel que par des solénoïdes supplémentaires ou bien comme montré dans la figure 5 par déclenchement périodique (toutes les 20 bouteilles) issu de la sortie en décharge (Sb1, Sb20), par exemple dès que la série des dispositifs « esclaves » comprend au moins environ 20 dispositifs. Le premier et le vingtième corps de vanne imposent alors une mise en place d'obturateur sur chacune de leur sortie de déclenchement (Sb1', Sb20'). Alternativement, l'installation et la maintenance de solénoïdes est aussi rendue plus complexe si leur nombre est accru.
Such an arrangement with N valve bodies coupled in series by a trigger channel has several disadvantages:
  • Since the valve bodies (Co1, Co2, ..., CoN) are generally made in a single geometry, whether they are associated with a "master or slave" ejection device, they require two different profiles of specific trigger inputs. alternatively (Edi, Edi ') (0 <i <N + 1), as well as three pressure output profiles (Sdi, Sbi, Sbi'). The number of these inlets and outlets complicates the design of the valve bodies and makes them more complex and expensive.
  • The valve bodies (Co1, Co2, ..., CoN) also require a large number of connections or plugs, caps or other shutters to be provided in order to allow coupling or locking in series of the trigger pressure distribution channel. said valves (Vi): for example in the figure, the first valve body (Co1) said "master" provides two shutters on its input (Ed1 ') and output (Sb1') boss to condemn a trigger type "slave"; the second valve body (Co2) of the "slave" type has two shutters on its inlet (Ed2) and its boss outlet (Sb2) to allow only a "slave" type tripping for the third valve body (Co3 ); the third valve body (Co3) of "slave" type provides two shutters on its input (Ed3) and its output (Sb3) boss to allow a trigger type "slave" for the fourth and last valve body (Co4); finally, the last and fourth valve body (Co4) type "slave" provides three shutters on its input (Ed4) and its two outputs (Sb4, Sb4 ') boss to finalize the triggering of the fourth device type "slave" . In addition to this high number of fittings and plugs / caps, these also require error-free installation and maintenance / control, which requires considerable effort for extended system installation and maintenance. Inevitably, the potential for leakage is proportional to the number of these connection or shutter components.
  • An arrangement comprising ejection devices in series according to the figure 1 provides a "master" device upstream is the trigger other "slave" devices arranged downstream under a series coupling. However, because of a risk that the solenoid (Sol) or / and the valve (V1) of the "master" device malfunction or failure accidentally, it is provided according to the figure 3 , a redundant priming device for protection, for example by placing a new solenoid on the second valve body, here (Co2) in figure 3 , or in the case of figure 1 , on the trigger input (Ed2). It turns out for performance reasons that the arrangement according to the figure 1 in the case where the number of bottles N is high, it is necessary to have an intermediate redundancy of mechanical trigger devices or by the pressure, such as by additional solenoids or as shown in FIG. figure 5 by periodic trigger (every 20 bottles) from the discharge output (Sb1, Sb20), for example as soon as the series of "slave" devices comprises at least about 20 devices. The first and the twentieth valve body then impose a shutter placement on each of their tripping output (Sb1 ', Sb20'). Alternatively, the installation and maintenance of solenoids is also made more complex if their number is increased.

Enfin, l'ensemble des entrées/sorties (Ed1, Ed1',Sb1) peut être un élément rapporté sur le corps de vanne (Co1), ou bien être intégré à celui-ci.Finally, all the inputs / outputs (Ed1, Ed1 ', Sb1) may be an element attached to the valve body (Co1), or be integrated therewith.

Un but de la présente invention est de proposer un corps de vanne à géométrie simple, particulièrement en limitant le nombre de ses entrées et sorties nécessaires pour l'interconnexion liées au déclenchement d'au moins deux corps de vanne géométriquement identiques, et indépendamment du fait que les dits corps de vanne soient associés à des dispositifs d'éjection de type « maitres » ou « esclaves ».An object of the present invention is to provide a simple geometry valve body, particularly by limiting the number of its inputs and outputs necessary for interconnection related to the triggering of at least two geometrically identical valve bodies, and independently of the fact that said valve bodies are associated with ejection devices of the type "masters" or "slaves".

Idéalement, ce corps de vanne devrait être facile à installer et à maintenir, particulièrement dès qu'il est intégré à un arrangement interconnectant plusieurs corps de vanne. Principalement, cela revient à limiter voire s'affranchir de trop nombreux moyens de raccordement et/ou d'obturation à disposer sur des entrées ou sorties du corps de vanne, particulièrement pour des interconnexions liées au déclenchement d'au moins deux corps de vanne géométriquement identiques.Ideally, this valve body should be easy to install and maintain, especially as it is integrated with an arrangement interconnecting multiple valve bodies. In principle, this amounts to limiting or even eliminating too many connection and / or closure means to be arranged on the inlets or outlets of the valve body, particularly for interconnections related to tripping of at least two geometrically identical valve bodies.

Par ailleurs, le corps de vanne proposé devrait être apte à supprimer une mise en place redondante ou périodique de dispositifs d'amorçage, tels que montré selon la figure 3 ou 5, par utilisation d'une bouteille asservie en déclenchement par la/les bouteilles dite(s) « maîtres », pour piloter une série de bouteilles suivantes dite « esclaves », si par exemple le nombre de dispositifs d'éjection excède 20.Furthermore, the proposed valve body should be able to suppress a redundant or periodic installation of priming devices, as shown in the figure 3 or 5 , by using a slaved cylinder triggered by the / said bottles (s) "master" to control a series of following bottles called "slaves", if for example the number of ejection devices exceeds 20.

Enfin, le corps de vanne proposé devrait être apte à augmenter les conditions dynamiques de déclenchement d'un arrangement comprenant plusieurs dispositifs d'éjection disposés en série.Finally, the proposed valve body should be able to increase the dynamic conditions of triggering an arrangement comprising several ejection devices arranged in series.

Ainsi, l'invention comprend deux revendications 1 et 10 proposant respectivement un tel corps de vanne et un arrangement d'au moins deux corps de vanne.Thus, the invention comprises two claims 1 and 10 respectively providing such a valve body and an arrangement of at least two valve bodies.

Un ensemble de sous-revendications présente également des avantages de l'invention.A set of subclaims also has advantages of the invention.

Figure 2 présente un arrangement de 4 dispositifs d'éjection principalement structurés selon la figure 1, c'est-à-dire dont les corps de vanne (Co1, Co2, Co3, Co4) sont accouplés en série au moyen d'un canal de déclenchement en décharge initiée par le premier dispositif d'éjection de type « maitre » comprenant la bouteille (Bo1) et un corps de vanne (Co1) selon l'invention.
Le corps de vanne selon l'invention peut être illustré le plus clairement sur la base du deuxième, du troisième ou du quatrième corps de vanne (Co2, Co3, Co4). Toutefois, sachant que les corps de vanne se doivent d'être si possible identiques pour faciliter leur conception et leur manufacture, le premier corps de vanne (Co1) est aussi conçu pour satisfaire aux exigences de l'invention. Considérons ainsi ici au plus simple le cas du deuxième corps de vanne (Co2) selon l'invention. Figure 2 presents an arrangement of 4 mainly structured ejection devices according to the figure 1 , i.e. whose valve bodies (Co1, Co2, Co3, Co4) are coupled in series by means of a discharge tripping channel initiated by the first "master" type ejection device comprising the bottle (Bo1) and a valve body (Co1) according to the invention.
The valve body according to the invention can be illustrated most clearly on the basis of the second, third or fourth valve body (Co2, Co3, Co4). However, knowing that the valve bodies must be identical if possible to facilitate their design and manufacture, the first valve body (Co1) is also designed to meet the requirements of the invention. Consider here the simplest case of the second valve body (Co2) according to the invention.

A partir d'un corps de vanne (Co2,...) comprenant :

  • une vanne de décharge (V2,...) d'un agent comprenant un gaz et/ou un liquide, la dite vanne déchargeant par un canal de sortie (Cs2,...) pour la décharge en pression à une sortie de décharge (Sd2,...) de corps de vanne ;
  • une entrée de déclenchement de vanne (Ed2,...) reliée par un canal de déclenchement (Cd2,...) à un dispositif d'amorçage de décharge de la vanne (V2,...) ;
  • une sortie en pression (Sb2,...) couplée par un canal de dérivation (D2,...) au canal de sortie (Cs2,...) ;
l'invention prévoit que le canal de dérivation (D2,...) est accouplé en pression au canal de déclenchement (Cd2,...) au moyen d'un canal de ramification (R2).From a valve body (Co2, ...) comprising:
  • a discharge valve (V2, ...) of an agent comprising a gas and / or a liquid, said valve discharging through an outlet channel (Cs2, ...) for the pressure discharge at a discharge outlet (Sd2, ...) of the valve body;
  • a valve trigger input (Ed2, ...) connected by a trigger channel (Cd2, ...) to a valve discharge priming device (V2, ...);
  • a pressure output (Sb2, ...) coupled by a bypass channel (D2, ...) to the output channel (Cs2, ...);
the invention provides that the bypass channel (D2, ...) is coupled in pressure to the trigger channel (Cd2, ...) by means of a branch channel (R2).

Par ce biais, il est possible qu'un canal « global » de déclenchement (Cd1, R1, Cc12, Cd2, R2, Cc23, Cd3, R3, Cc34, Cd4) de tous les dispositifs d'éjection soit configuré au travers des entrées et sorties usuelles (Edi, Sbi) (1<i<N) des dits dispositifs. En d'autres termes et en comparaison de la figure 1, les entrées et sorties (Edi', Sbi') spécifiques de déclenchement des corps de vanne ne sont plus nécessaires. Grâce à cette limitation du nombre d'entrée et sorties, la géométrie du corps de vanne est considérablement simplifiée, ainsi que sa conception, sa manufacture et son coût. Les efforts de montage ainsi que les risques et coût de maintenance sont aussi fort avantageusement réduits surtout dans le cas de mise en série de nombreux dispositifs d'éjection d'agent. En raison du nombre limité (ici 3) d'entrées et sorties (externes à la bouteille), le corps de vanne peut enfin être nettement plus compact et plus léger que des corps tels que représentés en figure 1. Il en ressort ainsi que le nombre de raccords ou obturateurs est aussi largement réduit : ici seul le quatrième et dernier corps de vanne (Co4) prévoit un obturateur sur sa sortie (Sb4) inutilisée de déclenchement. Le montage et la maintenance sont donc fort simplifiés, allégés et plus rapides.By this means, it is possible for a "global" trigger channel (Cd1, R1, Cc12, Cd2, R2, Cc23, Cd3, R3, Cc34, Cd4) of all the ejection devices to be configured through the inputs and usual outputs (Edi, Sbi) (1 <i <N) of said devices. In other words and in comparison to the figure 1 the specific inputs and outputs (Edi ', Sbi') for triggering the valve bodies are no longer necessary. With this limitation of the number of inputs and outputs, the geometry of the valve body is greatly simplified, as well as its design, manufacture and cost. Mounting efforts as well as the risks and cost of maintenance are also very advantageously reduced especially in the case of serialization of many devices ejection agent. Due to the limited number (here 3) of inputs and outputs (external to the bottle), the valve body can finally be significantly smaller and lighter than bodies such as represented in FIG. figure 1 . It follows that the number of connections or shutters is also greatly reduced: here only the fourth and last valve body (Co4) provides a shutter on its output (Sb4) unused tripping. Assembly and maintenance are therefore much simplified, lighter and faster.

Ainsi sous sa forme la plus simple, le corps de vanne selon l'invention comprend un nombre maximal d'entrée et de sorties utiles au déclenchement de la décharge (et externes à la bouteille), à savoir une entrée et une sortie de déclenchement de la décharge (Edi, Sbi'), une sortie en décharge (Sbi).Thus in its simplest form, the valve body according to the invention comprises a maximum number of inputs and outputs useful for triggering the discharge (and external to the bottle), namely an input and a trigger output of the discharge (Edi, Sbi '), a discharge exit (Sbi).

Il est à noter que l'invention prévoit une configuration unique de tous les corps de vanne afin de simplifier leur conception/manufacture/installation et plusieurs cas de figures se posent afin de converger vers la solution d'un unique corps de vanne optimal décrit ci-dessus :

  1. 1) Si le déclenchement « maitre » du premier corps de vanne (Co1) est mécanique via le canal (Cd1), l'accouplement en pression des canaux de dérivation (D1) et de déclenchement (Cd1) autorise le passage en pression de l'agent (liquide et/ou gaz) au travers de la ramification (R1).
  2. 2) De toutes les manières, les deuxième, troisième, etc. corps de vanne (Co2, Co3,...) exigent un déclenchement « esclave » sous pression via leur canal de déclenchement (Cd2, Cd3, ...) ce qui est toujours actif via le canal de dérivation (D1), et les canaux de ramification (R2, R3,...).
It should be noted that the invention provides a unique configuration of all valve bodies to simplify their design / manufacture / installation and several scenarios arise in order to converge towards the solution of a single optimal valve body described herein. -above :
  1. 1) If the "master" tripping of the first valve body (Co1) is mechanical via the channel (Cd1), the pressure coupling of the bypass (D1) and tripping channels (Cd1) allows the pressure to change to pressure. agent (liquid and / or gas) through the branching (R1).
  2. 2) Anyway, second, third, etc. valve bodies (Co2, Co3, ...) require a "slave" trigger under pressure via their trigger channel (Cd2, Cd3, ...) which is always active via the bypass channel (D1), and the branching channels (R2, R3, ...).

Dans le cas d'un arrangement à plusieurs dispositifs d'éjection couplés en série et quel que soit le type de déclenchement « maitre ou esclave », l'invention prévoit donc pour garantir une configuration unique/universelle de corps de vanne un canal de ramification (Ri) dit en pression, c'est-à-dire présentant une géométrie (cylindrique) creuse dans le corps de vanne. A cet effet, il est aussi préférentiel que les entrées de déclenchement (Ed1, Ed2, ...) et les canaux de déclenchement (Cd1, Cd2, ...) présentent une géométrie (cylindrique) creuse afin de permettre idéalement deux cas de figures :

  • garantir un canal de ramification (R1, R2,...) d'accouplement entre les canaux de dérivation (D1, D2,...) débouchant vers les sorties en pression (Sb1, Sb2,...) et les canaux de déclenchement (Cd1, Cd2,...) également sous pression. Ce cas de figure est nécessaire dans le cas d'un dispositif d'éjection « esclave ».
  • garantir de pouvoir disposer un élément mécanique percuteur fixé sur une entrée de déclenchement (Ed1, Ed2, ...) et mobile dans le canal de déclenchement (Cd1, Cd2, ...). Ce cas de figure est nécessaire dans le cas d'un dispositif d'éjection « maitre ».
In the case of an arrangement with several ejection devices coupled in series and regardless of the type of trigger "master or slave", the invention therefore provides to ensure a single / universal configuration of valve body branching channel (Ri) said pressure, that is to say having a geometry (cylindrical) hollow in the valve body. For this purpose, it is also preferable that the tripping inputs (Ed1, Ed2, ...) and the triggering channels (Cd1, Cd2, ...) have a hollow (cylindrical) geometry in order to ideally allow two cases of figures:
  • guarantee a coupling channel (R1, R2, ...) for coupling between the bypass channels (D1, D2, ...) leading to the pressure outputs (Sb1, Sb2, ...) and the triggering channels (Cd1, Cd2, ...) also under pressure. This case is necessary in the case of a "slave" ejection device.
  • guarantee to be able to have a mechanical striker element fixed on a trigger input (Ed1, Ed2, ...) and mobile in the trigger channel (Cd1, Cd2, ...). This case is necessary in the case of a "master" ejection device.

Le corps de vanne ainsi proposé selon l'invention apporte donc une solution bivalente suivant la modularité « maitre/esclave » associée aux arrangements en série de dispositifs d'éjection.The valve body thus proposed according to the invention therefore provides a two-way solution according to the "master / slave" modularity associated with the series arrangements of ejection devices.

Enfin, de part les accouplements en pression (Cdi, Ri, Di), le corps de vanne selon l'invention permet que, d'un dispositif d'éjection à l'autre, la pression et le débit utiles au déclenchement sont intrinsèquement régénérés dans d'excellentes conditions à chaque sortie (Sbi) de corps de vanne (maitre ou esclave) ainsi qu'à l'entrée (Edi+1) du prochain corps de vanne en série, à l'inverse de l'état de l'art où seule la première vanne maitre (V1) est le déclencheur de tous les autres dispositifs d'éjection, d'où une perte/fuite le long d'un ensemble de corps de vanne en série qui pourrait exiger une régénération (ajout d'une redondance intermédiaire d'amorçage par la pression) par exemple toutes les 20 bouteilles dans les cas usuels de dispositifs actuels d'extinction de feu. Au moyen du corps de vanne selon l'invention dans chacun des dispositifs d'éjection, un nombre illimité de dispositifs d'éjection couplés en série peut ainsi fort avantageusement être possible, si au moins le premier ou le dernier dispositif d'éjection de la série comprend un système d'amorçage en déclenchement (solénoïde).Finally, because of the pressure couplings (Cdi, Ri, Di), the valve body according to the invention allows that, from one ejection device to another, the pressure and the flow rate that are useful for triggering are intrinsically regenerated. under excellent conditions at each valve body outlet (Sbi) (master or slave) and at the inlet (Edi + 1) of the next valve body in series, in contrast to the state of the where only the first master valve (V1) is the trigger for all other ejectors, resulting in loss / leakage along a series valve body assembly that may require regeneration (addition of an intermediate pressure redundancy), for example every 20 bottles in the usual cases of current fire extinguishing devices. By means of the valve body according to the invention in each of the ejection devices, an unlimited number of ejection devices coupled in series can thus very advantageously be possible, if at least the first or the last ejection device of the ejection device. series includes triggering triggering system (solenoid).

A la figure 3 , il est présenté au moins un type de corps de vanne sous un arrangement d'au moins deux corps de vanne (Col, Co2, ..., CoN) selon la figure 1 incluant une redondance d'amorçage (= sous une configuration « maitre » redondante). L'arrangement comprend une pluralité N de dispositifs d'éjection couplés en série : le premier et le deuxième corps de vanne (Col, Co2) comprennent ainsi respectivement un solénoïde (So1, So2) en tant que dispositif d'amorçage en décharge des vannes (V1, V2). Cette configuration redondante des premiers et deuxième corps de vanne et leurs solénoïdes permet de palier à une panne d'une de leurs vannes et/ou déclencheurs (solénoïdes). Cette mise en redondance se fait par fixation du solénoïde (So2) sur l'entrée de déclenchement du deuxième corps de vanne à partir d'un arrangement selon la figure 1.To the figure 3 It is introduced at least one type of valve body in an arrangement of at least two valve body (Col, Co2, ..., CoN) of figure 1 including boot redundancy (= under a redundant "master" configuration). The arrangement comprises a plurality N of ejection devices coupled in series: the first and the second valve body (Col, Co2) thus respectively comprise a solenoid (So1, So2) as a triggering device for discharging the valves (V1, V2). This redundant configuration of the first and second valve bodies and their solenoids makes it possible to overcome a failure of one of their valves and / or triggers (solenoids). This redundancy is done by fixing the solenoid (So2) on the trigger input of the second valve body from an arrangement according to the figure 1 .

Parallèlement à la figure 3, la figure 4 présente au moins un type de corps de vanne selon l'invention et disposé sous un arrangement d'au moins deux corps de vanne (Co1, Co2, ..., CoN), ledit arrangement selon l'invention comprenant une redondance d'amorçage. Afin de palier à une panne d'une de leurs vannes et/ou déclencheurs (solénoïdes), un dispositif d'éjection « maitre » et un autre dispositif d'éjection « maitre » redondant peuvent être installés au début et en fin de série de l'arrangement de dispositifs couplés si chaque dispositif d'éjection (i=1, 2, ..., N) comprend le corps de vanne selon l'invention. En particulier, sachant qu'aucune régénération de débit/pression n'est requise artificiellement, il est possible de disposer fort avantageusement un nombre illimité de bouteille entre ces deux dispositifs redondants de type « maitre », sans devoir ajouter au moins un quelconque troisième dispositif d'amorçage (pour régénérer) toutes les 20 bouteilles par exemple.Along with the figure 3 , the figure 4 has at least one type of valve body according to the invention and arranged under an arrangement of at least two valve bodies (Co1, Co2, ..., CoN), said arrangement according to the invention comprising a priming redundancy . In order to overcome a failure of one of their valves and / or triggers (solenoids), a "master" ejection device and another redundant "master" ejection device can be installed at the beginning and at the end of the series. the arrangement of coupled devices if each ejection device (i = 1, 2, ..., N) comprises the valve body according to the invention. In particular, knowing that no regeneration of flow / pressure is required artificially, it is possible to have very advantageously an unlimited number of bottles between these two redundant devices of the "master" type, without having to add at least one third device priming (to regenerate) every 20 bottles for example.

Les dispositions suivantes s'appliquent aux figures 2 et 4 et permettent de présenter et décrire plus spécifiquement le corps de vanne selon l'invention et un arrangement comprenant au moins deux corps de vanne associés.The following provisions apply to figures 2 and 4 and allow to more specifically present and describe the valve body according to the invention and an arrangement comprising at least two associated valve bodies.

Le corps de vanne selon l'invention prévoit que le canal de déclenchement (Cd1, Cd2) comprend au moins un interstice vide permettant :

  • dans le cas d'un premier type de corps de vanne (Co1) dit maitre, d'y disposer un élément mécanique de poussée ou de créer une pression de déclenchement de vanne sous contrôle du module d'activation (So1) (= dispositif d'amorçage en décharge tel qu'un solénoïde) tel que respectivement un percuteur ou un générateur de pression ;
  • dans le cas du second type de corps de vanne (Co2) dit esclave, d'assurer une pression et un débit suffisants de la sortie de raccordement (Sb1) de la première vanne (V1) transmise à l'entrée de raccordement (Eb2) couplée au canal de déclenchement(Cd2) de la deuxième vanne (V2).
The valve body according to the invention provides that the trigger channel (Cd1, Cd2) comprises at least one empty gap allowing:
  • in the case of a first type of valve body (Co1) called master, to have there a mechanical element of thrust or to create a valve release pressure under control of the activation module (So1) (= device d discharge priming such as a solenoid) such as a striker or a pressure generator, respectively;
  • in the case of the second type of valve body (Co2) called slave, to ensure a sufficient pressure and flow of the connection output (Sb1) of the first valve (V1) transmitted to the connection input (Eb2) coupled to the trigger channel (Cd2) of the second valve (V2).

Ainsi, l'entrée/canal de déclenchement ou d'amorçage de chaque corps de vanne est de géométrie bivalente afin de pouvoir être activé par pression ou par voie mécanique.Thus, the entry / triggering channel or priming of each valve body is of bivalent geometry in order to be activated by pressure or mechanically.

De la sorte, les corps de vanne (Co1, Co2) de type maitre et esclave et leurs entrées et sorties peuvent ainsi être géométriquement identiques, donc universels.In this way, the master and slave valve bodies (Co1, Co2) and their inputs and outputs can thus be geometrically identical and therefore universal.

En particulier pour les dispositifs d'éjection « esclave », le canal de déclenchement (Cd3) est mis sous pression complémentaire par une mise sous pression due au canal de ramification (R2) au moyen du canal de dérivation (D2) extrait du canal de sortie (Cs2). En supposant que la première vanne (V1) ne puisse pas suffisamment être amorcée pour une raison technique, cette pression complémentaire peut lui permettre une activation forcée.In particular for the "slave" ejection devices, the triggering channel (Cd3) is pressurized further by pressurization due to the branching channel (R2) by means of the bypass channel (D2) extracted from the channel. output (Cs2). Assuming that the first valve (V1) can not be sufficiently primed for a technical reason, this additional pressure may allow it to forced activation.

Afin de bien assurer un maintien en pression et un débit suffisants en sortie (Sb1, Sb2,...) au-dessus de valeurs seuils pour garantir les déclenchements de toutes les vannes, chaque corps de vanne selon l'invention prévoit que, par exemple sur le deuxième corps de vanne (Co2) :

  • la ramification (R2) comprend un réducteur (Red1) de diamètre et de taille significative ou non.
    Et/ou
  • le canal de dérivation (D2) comprend un réducteur (Red2) de diamètre et de taille significative ou non.
In order to ensure a sufficient maintenance pressure and a sufficient output flow (Sb1, Sb2, ...) above threshold values to guarantee the triggering of all the valves, each valve body according to the invention provides that, by example on the second valve body (Co2):
  • branching (R2) comprises a reducer (Red1) of significant diameter and size or not.

  • the bypass channel (D2) comprises a reducer (Red2) of significant diameter and size or not.

Sur l'exemple du deuxième corps de vanne (Co2), le canal de dérivation (D2) comprend un clapet anti-retour (Car2) afin de conserver la pression de déclenchement du canal « global » de déclenchement (Cd1, R1, Cc12, Cd2, R2, Cc23, Cd3, R3, Cc34, Cd4) de tous les dispositifs d'éjection. Pendant, en fin, ou après l'éjection de l'agent (liquide et/ou gaz), un dispositif intégré ou non au corps de vanne ou à ce canal « global » permet de dépressuriser/retirer la pression de ce canal « global ».In the example of the second valve body (Co2), the bypass channel (D2) comprises a nonreturn valve (Car2) in order to maintain the triggering pressure of the "global" triggering channel (Cd1, R1, Cc12, Cd2, R2, Cc23, Cd3, R3, Cc34, Cd4) of all the ejection devices. During, at the end, or after the ejection of the agent (liquid and / or gas), a device integrated or not integrated with the valve body or with this "global" channel makes it possible to depressurize / withdraw the pressure of this "global" channel ".

Préférentiellement, un canal de déclenchement (Cd2), la ramification (R2), le canal de dérivation (D2), les réducteurs éventuels (Red1 et/ou Red2) et le clapet anti-retour (Car2) sont internes au premier corps de vanne, idéalement de manière monobloc. Il en résulte un corps de vanne robuste et compact.Preferably, a trigger channel (Cd2), the branch (R2), the bypass channel (D2), the possible reducers (Red1 and / or Red2) and the non-return valve (Car2) are internal to the first valve body ideally monoblock. The result is a robust and compact valve body.

L'arrangement selon l'invention est adapté afin que les corps de vanne des première et deuxième vannes et leurs entrées et sorties soient géométriquement simplement identiques/universels.The arrangement according to the invention is adapted so that the valve bodies of the first and second valves and their inputs and outputs are geometrically simply identical / universal.

Le dit arrangement peut s'étendre à au moins trois corps de vanne selon l'invention comprenant respectivement une des vannes (V1, V2) et une troisième vanne (V3). Les dits corps de vannes sont fort simplement couplés en série, en ce qu'un canal de connexion (Cc23) relie sous pression une sortie de raccordement (Sb2) du deuxième corps de vanne (V2) à une entrée de déclenchement (Ed3) couplée à un canal (Cd3) de déclenchement de la troisième vanne (V3).The said arrangement can extend to at least three valve bodies according to the invention respectively comprising one of the valves (V1, V2) and a third valve (V3). Said valve bodies are simply simply coupled in series, in that a connection channel (Cc23) connects under pressure a connection output (Sb2) of the second valve body (V2) to a coupled trigger input (Ed3). a channel (Cd3) for tripping the third valve (V3).

Plus généralement, l'arrangement selon l'invention peut comprendre au moins une pluralité (N) de corps de vanne (Co1, Co2, ..., CoN) comprenant respectivement une des vannes (V1, V2, ..., VN), les dits corps de vanne étant disposés en série pour lequel la première vanne (V1) est couplée au moyen du canal de déclenchement (Cd1) au module d'activation (So1) d'amorçage en pression de sortie de ladite première vanne et une autre quelconque des vannes (Vi) avec 1<i<N est couplée au moyen d'un canal de déclenchement (Cdi) à éventuellement un second module d'activation (So2) d'amorçage en pression de sortie de la dite quelconque des vannes (Vi), les dites autres vannes (Vk) (k≠1 ; k≠i) étant libres de couplage à un module d'activation, idéalement i=N.More generally, the arrangement according to the invention may comprise at least a plurality (N) of valve bodies (Co1, Co2,..., CoN) respectively comprising one of the valves (V1, V2, ..., VN). , said valve bodies being arranged in series for which the first valve (V1) is coupled by means of the trigger channel (Cd1) to the activation module (So1) for priming the outlet pressure of said first valve and a any other of the valves (Vi) with 1 <i <N is coupled by means of a triggering channel (Cdi) to possibly a second activation module (So2) for priming the output pressure of said one of the valves (Vi), said other valves (Vk) (k ≠ 1; k ≠ i) being free of coupling to an activation module, ideally i = N.

Le dit arrangement permet avantageusement que N>20 par exemple, idéalement et pratiquement N<1000. Ainsi, des séries de fort nombreux dispositifs d'éjection couplés sont réalisables et ne comprennent simplement qu'un ou, pour une protection sécuritaire de redondance, que deux modules d'activation (So1, So2).Said arrangement advantageously allows N> 20 for example, ideally and practically N <1000.
