Description

L'invention se rapporte aux extincteurs d'incendie pour CO₂ et a plus précisemment pour objet une nouvelle vanne de distribution à sécurités multiples.The invention relates to fire extinguishers for CO₂ and more specifically relates to a new multiple safety distribution valve.

Les extincteurs du type à CO₂ sont, on le sait, essentiellement constitués d'un réservoir sur une ouverture duquel est vissée une tête ou vanne de distribution du gaz vers un tromblon de sortie. La vanne est équipée d'une poignée de portage et d'un levier de commande qui, une fois déverrouillé, agit sur un poussoir de manoeuvre d'un clapet obturateur dont l'ouverture fait communiquer le réservoir au tromblon. La chambre de distribution intérieure à la vanne, en amont du clapet, est reliée à un dispositif de sécurité de surpression utilisant un opercule qui se brise à une pression déterminée et provoque le vidage du réservoir par des petits orifices de sécurité.Fire extinguishers of the CO₂ type are, as we know, essentially constituted by a reservoir onto an opening of which is screwed a head or valve for distributing the gas towards an outlet blunderbolt. The valve is equipped with a carrying handle and a control lever which, once unlocked, acts on a push-button for operating a shutter valve, the opening of which communicates the tank with the blunderbuss. The distribution chamber inside the valve, upstream of the valve, is connected to an overpressure safety device using a seal which breaks at a determined pressure and causes the tank to be emptied by small safety orifices.

Une vanne de ce type est donc vissée à force sur le réservoir, et quand il s'agit de remplacer le CO₂, après l'utilisation de l'extincteur ou une fuite de gaz par le dispositif de sécurité, il convient de dévisser la vanne et de la remplacer car elle n'est plus réutilisable. Le fait que cette vanne ne soit pas rénovable est un inconvénient économique certain auquel la Demanderesse entend par conséquent remédier.A valve of this type is therefore forcibly screwed onto the tank, and when it comes to replacing the CO₂, after using the extinguisher or a gas leak by the safety device, the valve should be unscrewed and replace it because it is no longer reusable. The fact that this valve cannot be renovated is a certain economic disadvantage which the Applicant therefore intends to remedy.

Hormis cela, il est apparu que cette vanne connue n'offre pas toujours toute garantie de sécurité en cas de choc accidentel. En effet l'appareil est livré généralement sans que le tromblon soit vissé sur la vanne.Apart from that, it appeared that this known valve does not always offer any guarantee of safety in the event of accidental impact. In fact, the device is generally delivered without the blunderbuss being screwed onto the valve.

Certes la goupille de verrouillage qui bloque le levier de commande et par conséquent l'ouverture du clapet est censée garantir cet incident. Mais son déclenchement accidentel n'est toutefois pas totalement exclu. En outre le maniement de l'appareil, l'arrachage de la goupille et l'orientation du réservoir vers le foyer d'incendie liée à la position du tromblon par rapport à la vanne, présentent des difficultés qui ont conduit la Demanderesse à repenser une nouvelle vanne de distribution qui complète la sécurité passive, connue en soi, mettant en oeuvre l'opercule brisable, par une sécurité active en cas d'ouverture accidentelle du clapet quand le tromblon n'est pas monté.Certainly the locking pin which blocks the control lever and consequently the opening of the valve is supposed to guarantee this incident. However, its accidental triggering is not entirely excluded, however. In addition, the handling of the device, the pulling out of the pin and the orientation of the tank towards the fire hearth linked to the position of the blunderbuss relative to the valve, presents difficulties which have led the Applicant to rethink a new distribution valve which completes the passive safety, known per se, putting in place operates the breakable cover, by active safety in case of accidental opening of the valve when the blunderbuss is not mounted.

Cette disposition est particulièrement importante quand on sait à quelle pression peut s'échapper le CO₂ de la vanne de distribution. La vanne de distribution selon l'invention apporte aussi un certain nombre d'avantages par rapport aux vannes connues notamment en ce qu'elle est réutilisable après remplacement du CO₂, et en ce qu'elle est mieux adaptée au montage direct d'un tromblon, ou au montage du tromblon en haut d'un flexible.This is particularly important when you know what pressure CO peut can escape from the distribution valve. The distribution valve according to the invention also brings a certain number of advantages compared to known valves in particular in that it is reusable after replacement of the CO₂, and in that it is better suited to the direct mounting of a blunderbuss , or when mounting the blunderbuss at the top of a hose.

L'invention a donc pour objet une vanne de distribution pour extincteur d'incendie, raccordé par un tube-plongeur à un réservoir de CO₂, comportant un levier de commande manoeuvrable après action sur un organe de déverrouillage pour assurer l'ouverture d'un clapet obturateur qui met en communication une chambre interne de distribution reliée à un réservoir de CO₂, avec un tromblon de sortie de gaz, ladite chambre interne étant reliée à un purgeur de sécurité à opercule brisable constituant une sécurité passive en cas de surpression dans le réservoir, ladite vanne étant équipée, d'au moins un dispositif complémentaire de sécurité active en cas d'ouverture accidentelle du clapet, dispositif qui est localisé au niveau du raccord de la vanne au tromblon, et d'au moins un dispositif complémentaire au dispositif de sécurité passive à purgeur.The invention therefore relates to a distribution valve for fire extinguisher, connected by a dip tube to a CO₂ tank, comprising a control lever that can be maneuvered after action on an unlocking member to ensure the opening of a shutter valve which connects an internal distribution chamber connected to a CO₂ tank, with a gas outlet blunderbuss, said internal chamber being connected to a safety vent valve with breakable cover constituting passive safety in the event of overpressure in the tank , said valve being equipped with at least one additional active safety device in the event of accidental opening of the valve, a device which is located at the connection of the valve to the blaster, and at least one device complementary to the passive safety valve.

Selon une caractéristique particulière de l'invention, le dispositif complémentaire de sécurité active est constitué d'une bille placée à l'intérieur du raccord, qui est appliquée par un petit ressort contre une bague rapportée à l'intérieur dudit raccord, et le dispositif complèmentaire de sécurité passive est constitué d'un capot protecteur ayant la forme d'une double-coquille qui enveloppe complétement la vanne de distribution et qui est muni de lumières faisant communiquer l'intérieur du capot avec l'extérieur.According to a particular characteristic of the invention, the additional active safety device consists of a ball placed inside the fitting, which is applied by a small spring against a ring attached to the inside of said fitting, and the device additional passive safety system consists of a cover protector in the form of a double-shell which completely envelops the distribution valve and which is provided with lights communicating the inside of the cover with the outside.

Selon une autre caractéristique de l'invention, la chambre interne de distribution se développe horizontalement dans le corps de vanne et communique par un passage avec le raccord de sortie vers le tromblon, raccord qui est orienté vers le haut, et le purgeur de sécurité à opercule brisable est vissé sur un bouchon qui ferme la chambre interne de distribution.According to another characteristic of the invention, the internal distribution chamber develops horizontally in the valve body and communicates by a passage with the outlet connection towards the blaster, connection which is oriented upwards, and the safety trap at breakable cover is screwed onto a stopper which closes the internal distribution chamber.

D'autres caractéristiques particulières et avantages de l'invention ressortiront de la description qui va suivre d'une forme de réalisation faisant référence aux dessins annexés qui représentent :Other particular characteristics and advantages of the invention will emerge from the description which follows of an embodiment referring to the appended drawings which represent:

figure 1 une vue schématique en élévation de l'extincteur.Figure 1 a schematic elevational view of the fire extinguisher.

figure 2 une vue en coupe à plus grande échelle de la vanne de distribution.Figure 2 a sectional view on a larger scale of the dispensing valve.

La figure 1 présente une vue générale d'un réservoir 2 d'extincteur sur la partie ouverte duquel est montée une vanne de distribution 1 qui fait communiquer le réservoir et le tromblon 3 de projection du CO₂.Figure 1 shows a general view of a fire extinguisher tank 2 on the open part of which is mounted a distribution valve 1 which communicates the tank and the blaster 3 for projecting CO₂.

La vanne, ainsi que le réservoir sont maintenus par une poignée de portage 4 et un levier de commande 5 permet d'ouvrir la vanne 1 sous réserve du déverrouillage d'une tirette de verrouillage 6. Enfin la vanne est coiffée d'un capot de protection 7 ayant la forme d'une double coquille maintenue à ladite vanne par les vis 8.The valve, as well as the reservoir are held by a carrying handle 4 and a control lever 5 makes it possible to open the valve 1 subject to the unlocking of a locking pull tab 6. Finally the valve is capped with a cover. protection 7 having the form of a double shell held at said valve by screws 8.

En se référant maintenant à la figure 2, on décrit la vanne de distribution 1. Le corps de vanne renferme un conduit intérieur 10 qui met en communication le réservoir 2 avec une chambre interne de distribution 11, elle-même reliée par un passage 12 au raccord de sortie 13. On remarquera que le conduit intérieur 10, sensiblement vertical, débouche dans la chambre 11 qui se développe horizontalement dans le corps de vanne, et que le passage 12 est en communication directe avec le raccord de sortie 13 orienté vers le haut. Les avantages de cette disposition particulière apparaitront plus loin. Un clapet obturateur 14, appliqué contre son siège par un ressort 15 et situé dans la chambre de distribution obture le passage 12. Le clapet peut être ouvert par action sur le levier de commande 5 agissant sur un poussoir 16 en appui contre ledit clapet, quand la tirette 6 a été déverrouillée. La chambre 11 est fermée par un bouchon 17 muni d'une ouverture centrale dans laquelle est vissé un purgeur de sécurité 18 obturé par un opercule 19, qui se brise dès que la pression du CO₂ dans la chambre interne dépasse une valeur prédéterminée. Ce purgeur à sécurité passive est avantageusement placé coaxialement au bouchon 17. Avant remplissage, en démontant le bouchon, on peut accéder aisément au clapet obturateur sans avoir à désolidariser la vanne du réservoir.Referring now to FIG. 2, the distribution valve 1 is described. The valve body contains an internal conduit 10 which places the reservoir 2 in communication with an internal distribution chamber 11, itself connected by a passage 12 to the outlet connection 13. It will be noted that the substantially vertical inner conduit 10 opens into the chamber 11 which develops horizontally in the valve body, and that the passage 12 is in direct communication with the outlet connector 13 facing upwards. The advantages of this particular arrangement will appear below. A shutter valve 14, applied against its seat by a spring 15 and located in the distribution chamber closes the passage 12. The valve can be opened by action on the control lever 5 acting on a pusher 16 bearing against said valve, when zipper 6 has been unlocked. The chamber 11 is closed by a plug 17 provided with a central opening into which is screwed a safety trap 18 closed by a cover 19, which breaks as soon as the pressure of the CO₂ in the internal chamber exceeds a predetermined value. This passive safety trap is advantageously placed coaxially with the plug 17. Before filling, by removing the plug, the shutter valve can be easily accessed without having to separate the valve from the tank.

Cette sécurité passive est complétée par une sécurité active localisée au niveau du raccord de sortie 13. Elle comprend essentiellement une bille 20 d'un diamètre inférieur au diamètre du raccord, qui est maintenue par un petit ressort 21, appliquée contre une bague 22 rapportée à l'intérieur du raccord. Quand le tromblon n'est pas vissé sur celui-ci, la bille obture l'orifice central de la bague, sous l'action du ressort 21. Normalement, puisque le clapet obturateur 14 est fermé, il n'y a pas de pression de CO₂ dans le passage 12. Néammoins en cas d'action intempestive sur le levier de commande 5 ou en cas de choc, qui aboutirait à l'ouverture du clapet, la forte pression de CO₂ qui s'établirait dans le passage 12 complèterait la poussée sur la bille 20 et la fermeture étanche du raccord. Ainsi, tant que le tromblon 3 n'est pas monté sur la vanne, il n'y a aucun risque d'échappement de gaz. Par contre le vissage du tromblon 3 sur le raccord 13 a pour effet d'enfoncer la bille dans l'intérieur du raccord à l'encontre du petit ressort 21, et de mettre ainsi en communication le passage 12 avec le tromblon. Cela se fait par exemple grâce à un pointeau placé dans la tubulure d'admission du tromblon.This passive safety is supplemented by active safety located at the outlet connection 13. It essentially comprises a ball 20 with a diameter less than the diameter of the connection, which is held by a small spring 21, applied against a ring 22 attached to inside the fitting. When the blunderbuss is not screwed onto it, the ball closes the central orifice of the ring, under the action of the spring 21. Normally, since the shutter valve 14 is closed, there is no pressure CO₂ in the passage 12. However, in the event of untimely action on the control lever 5 or in the event of an impact, which would lead to the opening of the valve, the high pressure of CO₂ which would be established in the passage 12 would complete the thrust on the ball 20 and the tight closure of the fitting. Thus, as long as the blunderbuss 3 is not mounted on the valve, there is no risk of gas escape. On the other hand, the screwing of the blunderbuss 3 on the fitting 13 has the effect of driving the ball into the interior of the fitting against the small spring 21, and thus putting the passage 12 into communication with the blunderbuss. This is done for example thanks to a needle placed in the intake pipe of the blunderbuss.

Une sécurité supplémentaire est assurée par le capot protecteur 7. En effet celui-ci enveloppe complètement la vanne de distribution 1. Du côté du bouchon 17 il est percé de lumières 23 qui font communiquer l'intérieur du capot avec l'extérieur. L'utilisateur de l'extincteur n'a donc pas accès au bouchon 17 sauf à démonter les vis 8. Il n'y a donc pas de risque de dévissage malencontreux du bouchon ni du purgeur. En outre, en cas de rupture de l'opercule de sécurité 19, le CO₂ s'échappant du purgeur est diffusé vers l'extérieur par les lumières 23.Additional security is provided by the protective cover 7. In fact, the cover completely envelops the distribution valve 1. On the side of the plug 17 it is pierced with lights 23 which make the inside of the cover communicate with the outside. The user of the extinguisher therefore has no access to the plug 17 except for removing the screws 8. There is therefore no risk of unintentional unscrewing of the plug or of the trap. In addition, in the event of the safety cover 19 breaking, the CO₂ escaping from the trap is diffused towards the outside by the lights 23.

Au niveau de son raccordement avec le réservoir 2 la vanne de distribution 1 est vissée audit réservoir mais se termine - dans le prolongement du conduit 10, par un tube plongeur 24 clipsé sur la vanne par un clips d'agrafage 25. Le montage et le démontage de la vanne s'en trouvent simplifiés. La vanne ainsi équipée, l'appareil est facilement saisi et manoeuvré par l'utilisateur. Grâce à la tirette de déverrouillage qui se trouve au-dessus, et qui se déplace vers le haut, l'utilisateur - qu'il soit droitier ou gaucher saura aisément déverrouiller l'appareil et actionner le levier de commande. On notera aussi que la sortie verticale du raccord 13, qui se prête au montage direct du tromblon comme le montre la figure 1, facilite aussi le montage d'un flexible entre le raccord et le tromblon.At its connection with the tank 2 the distribution valve 1 is screwed to said tank but ends - in the extension of the conduit 10, by a dip tube 24 clipped on the valve by a stapling clips 25. The mounting and the disassembly of the valve is thereby simplified. With the valve thus equipped, the device is easily gripped and operated by the user. Thanks to the unlocking zipper which is located above, and which moves upwards, the user - whether right-handed or left-handed - can easily unlock the device and actuate the control lever. It will also be noted that the vertical outlet of the connector 13, which lends itself to direct mounting of the blinker as shown in Figure 1, also facilitates the mounting of a hose between the connector and the blinker.

L'invention ne se limite pas à l'exemple de réalisation décrit, mais en englobe aussi les variantes constructives.The invention is not limited to the embodiment described, but also encompasses the constructive variants.
