Abstract

The valve consists of a housing (12) for mounting on the extinguisher reservoir (2), containing a movable shutter (16) which opens by moving axially away from the reservoir after the removal of a locking member (34) that holds it in its closed position. The shutter slides in a bore (18) in the valve housing which has an outlet (30) for the extinguishing substance and a seat (20) for the shutter, while a spring (54) moves the shutter away from the seat and opens the outlet when the locking member is removed.

Description

L'invention a trait à un robinet pour extincteur portable à pression permanente et à un extincteur portable à pression permanente équipé d'un tel robinet.The invention relates to a tap for a portable fire extinguisher. with permanent pressure and a portable pressure fire extinguisher permanent fitted with such a tap.

Un robinet est monté sur le débouché d'un réservoir d'extincteur à pression permanente pour contrôler la décharge du fluide de traitement d'incendie. Ce robinet peut être relié à un diffuseur ou à un tuyau flexible à l'extrémité libre duquel est montée une tête de pulvérisation permettant de diriger le produit, cette tête étant éventuellement équipée d'un mécanisme d'obturation commandée.A tap is mounted on the outlet of a fire extinguisher tank at permanent pressure to control the discharge of the fire treatment fluid. This tap can be connected to a diffuser or flexible hose at the free end which is mounted a spray head allowing direct the product, this head possibly being equipped a controlled shutter mechanism.

Par le document FR-A-2 741 811, on connaít un extincteur à pression permanente comprenant un robinet pourvu d'une tête de pulvérisation. Une gâchette de cette tête de pulvérisation est en prise avec un levier prévu pour déplacer un clapet du robinet de l'extincteur contre la force de la pression régnant dans le réservoir, afin de mettre en communication le volume intérieur du réservoir et un orifice de sortie du robinet. Le tait que le clapet est déplacé à l'encontre de la pression régnant dans le réservoir rend cette manoeuvre relativement difficile dans la mesure où cette pression s'oppose au mouvement d'ouverture du clapet. En outre, un moyen de verrouillage du clapet en position ouverte doit être prévu, faute de quoi le clapet est refermé dès que l'utilisateur cesse d'exercer sur le levier un effort de déplacement du clapet, en particulier lorsqu'il se sert de l'extincteur pour éteindre un incendie. Une petite tige de verrouillage est utilisée pour ce faire, mais cette tige est de faibles dimensions et le plus grand soin doit être apporté lors du montage pour qu'elle soit positionnée correctement, et au cours de la durée de vie de l'extincteur pour qu'elle ne soit pas égarée, par exemple lors des opérations de maintenance de l'extincteur. En outre, le système connu prévoit la manoeuvre du clapet par la tête de pulvérisation, ce qui impose le positionnement relatif du clapet, de son levier de commande et de la tête de pulvérisation dans la position de repos. Ceci peut ne pas être opportun, notamment sur le plan ergonomique. Enfin, lors d'une manoeuvre rapide de la tête de pulvérisation, notamment en cas de panique devant un incendie, l'utilisateur peut ne pas tirer sur la tête de pulvérisation dans un sens permettant la manoeuvre du levier de commande du clapet, ce qui induit la rupture de la gâchette et la non-ouverture du robinet.Document FR-A-2 741 811 discloses a fire extinguisher permanent pressure comprising a tap with a head spray. A trigger of this spray head is engaged with a lever provided to move a valve from the fire extinguisher valve against prevailing pressure in the tank, in order to port the volume inside the tank and a tap outlet. The was that the valve was moved against the pressure reigning in the tank makes this maneuver relatively difficult since this pressure is opposed to the movement opening the valve. In addition, a locking means the valve in the open position must be provided, otherwise the valve is closed as soon as the user stops exercising on the lever an effort to move the valve, in particular when using the extinguisher to extinguish a fire. A small locking rod is used for do this but this rod is small and the most great care must be taken during assembly for it to be positioned correctly, and over the lifetime of the extinguisher so that it is not lost, for example when fire extinguisher maintenance operations. In addition, the known system provides for the operation of the valve by the head of spraying, which requires the relative positioning of the valve, its control lever and the spray head in the rest position. This may not be timely, especially ergonomically. Finally, during a rapid operation of the spray head, especially in the event of panic in the face of fire, user may not fire on the spray head in a direction allowing the operation of the valve control lever, which induces the trigger failure and failure to open the valve.

Par ailleurs, il est connu de DE-A-42 25 997 de réaliser une vanne à ouverture rapide au moyen d'une cartouche pyrotechnique apte à agir sur un piston, de telle sorte que sont libérées des billes d'ancrage d'un élément cylindrique dans un manchon fixe, l'élément cylindrique étant alors libéré pour permettre un mouvement de retrait d'un clapet monté en partie supérieure d'un réservoir. Un tel système est particulièrement complexe sur le plan mécanique et peut présenter des défauts de fiabilité, notamment en cas de grippage des billes qui peuvent demeurer dans leur logement pendant plusieurs années. En outre, la charge pyrotechnique doit être alimentée en courant pour déclencher l'étincelle nécessaire à l'expansion du gaz, ce qui requiert l'utilisation d'une ligne d'alimentation électrique à partir d'une source de tension, une telle construction n'étant pas adaptée à un extincteur portable. Dans tous les cas, un tel système est particulièrement onéreux et doit être réservé à des installations élaborées.Furthermore, it is known from DE-A-42 25 997 to carry out a quick-opening valve by means of a cartridge pyrotechnic capable of acting on a piston, so that are released from the anchor balls of a cylindrical element in a fixed sleeve, the cylindrical element then being released to allow a withdrawal movement of a valve mounted in upper part of a tank. Such a system is particularly mechanically complex and may have reliability defects, especially in the event of seizure of the balls who can stay in their accommodation for several years. In addition, the pyrotechnic charge must be supplied running to trigger the spark needed for expansion gas, which requires the use of a line power supply from a voltage source, such a construction not being suitable for a fire extinguisher portable. In any case, such a system is particularly expensive and must be reserved for installations developed.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention, en proposant un robinet dont l'ouverture est facilitée par rapport aux robinets de l'état de la technique et qui ne nécessite ni l'utilisation d'un levier de manoeuvre d'un clapet, ni l'utilisation d'un organe de verrouillage d'un tel levier en position ouverte du robinet, ni le recours à un système électro-mécanique complexe avec charge pyrotechnique.It is to these disadvantages that we hear more particularly remedy the invention, by proposing a tap whose opening is facilitated compared to the taps of the state of the technical and which does not require the use of a operation of a valve, or the use of a locking of such a lever in the open position of the valve, nor the use of a complex electro-mechanical system with pyrotechnic charge.

Dans cet esprit, l'invention concerne un robinet pour extincteur portable à pression permanente, ce robinet comprenant un corps prévu pour être monté sur l'orifice d'un réservoir de fluide de traitement d'incendie et un clapet mobile en translation entre une position de d'ouverture et une position de fermeture du robinet, alors que ce clapet est prévu pour passer de la position de fermeture à la position d'ouverture du robinet par un mouvement de translation dans un sens d'éloignement par rapport au réservoir. Ce robinet comprend un organe amovible de verrouillage du clapet en position de fermeture du robinet, cet organe étant prévu pour s'opposer au mouvement de translation du clapet dans le sens d'éloignement par rapport au réservoir.In this spirit, the invention relates to a tap for portable fire extinguisher with permanent pressure, this tap comprising a body intended to be mounted on the orifice of a tank of fire treatment fluid and a movable valve in translation between an open position and a valve closing position, while this valve is intended to pass from the closed position to the position opening of the tap by a translational movement in a sense of distance from the tank. This tap includes a removable valve locking member in valve closing position, this member being provided for oppose the movement of translation of the valve in the direction distance from the tank.

Grâce à l'invention, le mouvement du clapet, lors de l'ouverture du robinet ne nécessite pas de vaincre la pression régnant à l'intérieur du réservoir, mais a lieu dans un sens compatible avec cette pression, quelle que soit sa valeur. Le robinet peut être construit de telle sorte que le clapet s'efface du trajet du fluide vers l'orifice de sortie du robinet, c'est-à-dire est écarté de ce trajet et ce, sans utilisation d'un levier ou de moyens compliqués de blocage en position ouverte. L'organe amovible de verrouillage peut être aisément manipulé par un utilisateur et être formé d'un dispositif de construction simple, de telle sorte que son coût est modique alors qu'il remplit sa fonction de façon particulièrement fiable, sans risque de coincement et/ou nécessité d'une alimentation électrique.Thanks to the invention, the movement of the valve, during opening the tap does not require overcoming the pressure prevailing inside the tank but takes place in one direction compatible with this pressure, whatever its value. The valve can be constructed so that the valve disappears from the path of the fluid towards the outlet of the tap, that is to say is removed from this path and this, without use of a lever or complicated means of locking in open position. The removable locking member can be easily handled by a user and formed of a simple construction device, so that its cost is modest while fulfilling its function particularly reliable, without risk of jamming and / or necessity a power supply.

Selon un premier aspect avantageux de l'invention, le corps comprend un alésage dans lequel est logé, à coulissement, le clapet, un conduit de sortie du robinet étant ménagé dans ce corps et débouchant dans cet alésage. Cet alésage guide efficacement le clapet sur toute la longueur de sa course. Des moyens aptes à charger élastiquement le clapet dans un sens d'éloignement par rapport au réservoir peuvent être prévus. En particulier, l'alésage forme avantageusement un épaulement interne d'appui d'un ressort de compression, alors que le clapet porte un épaulement externe correspondant, le ressort étant disposé entre ces épaulements. D'autre part, l'alésage définit avantageusement un siège de portée du clapet, alors que le clapet porte un joint torique apte à venir en appui contre ce siège.According to a first advantageous aspect of the invention, the body includes a bore in which is housed, slidingly, the valve, a tap outlet conduit being provided into this body and opening into this bore. This bore effectively guides the valve over the entire length of its race. Means capable of elastic loading of the valve away from the tank can be planned. In particular, the bore advantageously forms an internal support shoulder for a compression spring, while the valve carries a corresponding external shoulder, the spring being disposed between these shoulders. On the other hand, the bore advantageously defines a seat of range of the valve, while the valve carries an O-ring suitable for come to rest against this seat.

Selon un mode de réalisation de l'invention, le clapet est apte à passer de sa position de fermeture du robinet à sa position d'ouverture sous l'effet des seules forces de pression exercées par le fluide contenu dans le réservoir, sans action d'un moyen mécanique tel qu'un ressort, le clapet étant pourvu d'au moins un joint d'étanchéité avec la surface radiale d'un alésage du corps dans lequel peut coulisser le clapet.According to one embodiment of the invention, the valve is able to move from its closed valve position to its open position under the effect of the forces of pressure exerted by the fluid contained in the reservoir, without the action of a mechanical means such as a spring, the valve being provided with at least one seal with the surface radial of a bore in the body in which the valve.

Selon un autre aspect avantageux de l'invention, l'organe de verrouillage est avantageusement une goupille extractible prévue pour être reçue dans le corps du robinet dans une position globalement perpendiculaire à la direction de déplacement du clapet. La face du clapet opposée au réservoir peut porter un pion apte à pénétrer dans un logement correspondant de cette goupille. Ce pion contribue au blocage en position de la goupille par rapport au robinet. On peut également prévoir que le fond de l'alésage comprend un logement de réception de ce pion en position d'ouverture du clapet.According to another advantageous aspect of the invention, the organ advantageously is a removable pin intended to be received in the valve body in a position generally perpendicular to the direction of moving the valve. The side of the valve opposite the tank can carry a pawn capable of entering a corresponding housing of this pin. This pawn contributes to blocking in position of the pin in relation to the valve. We can also provide that the bottom of the bore includes a housing for receiving this pin in the open position of the valve.

En variante, on peut prévoir que le fond de l'alésage porte un moyen d'amortissement de l'impact du clapet contre ce fond.Alternatively, it can be provided that the bottom of the bore carries a means of damping the impact of the valve against this background.

L'invention concerne également un extincteur portable à pression permanente qui comprend un robinet tel que précédemment décrit. Un tel extincteur est particulièrement simple d'utilisation puisqu'il suffit de libérer le clapet pour que celui-ci ne s'oppose plus au passage du fluide de traitement d'incendie sans prendre des précautions particulières pour bloquer le clapet en position d'ouverture.The invention also relates to a portable fire extinguisher with permanent pressure which includes a tap as above described. Such a fire extinguisher is particularly simple of use since it suffices to release the valve so that this no longer prevents the passage of the treatment fluid without taking special precautions to lock the valve in the open position.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaítront plus clairement à la lumière de la description qui va suivre de deux modes de réalisation d'un extincteur conforme à son principe donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

Un clapet 16 est mobile à l'intérieur d'un alésage 18 formé dans le corps 12. On note X-X' l'axe de symétrie de l'alésage 18. L'alésage 18 définit un siège 20 à portée conique destiné à coopérer avec le clapet 16 en position fermée du robinet 10, comme représenté aux figures 3 et 4. Le clapet 16 comprend une tête 22 de diamètre inférieur à la partie principale 24 du clapet 16, de telle sorte qu'il définit un épaulement 26 de réception d'un joint torique 28, ce joint étant prévu pour venir en appui contre le siège 20 dans la position des figures 2 à 4.As can be seen more clearly from FIG. 2, a tap 10 is provided to be mounted on the orifice 2 a of the reservoir 2 and comprises a body 12 intended to be screwed into the orifice 2 a , thanks to an external thread 12 a , by being connected to a dip tube 14 whose open lower end, not shown, is disposed within the fire treatment fluid. A valve 16 is movable inside a bore 18 formed in the body 12. The axis of symmetry of the bore 18 is denoted XX ′. The bore 18 defines a seat 20 with a conical bearing intended to cooperate with the valve 16 in the closed position of the valve 10, as shown in Figures 3 and 4. The valve 16 comprises a head 22 of diameter less than the main part 24 of the valve 16, so that it defines a shoulder 26 for receiving an O-ring 28, this seal being intended to come into abutment against the seat 20 in the position of FIGS. 2 to 4.

Un perçage 30 est prévu dans le corps 12 selon une direction Y1-Y1' globalement perpendiculaire à l'axe X-X' et reçoit un raccord 32 de connexion du tube flexible 6.A bore 30 is provided in the body 12 in a direction Y 1 -Y 1 ′ generally perpendicular to the axis XX ′ and receives a connector 32 for connecting the flexible tube 6.

Dans la position des figures 2 à 4, le clapet 16 obture l'alésage 18 au niveau du siège 20 et le perçage 30 au niveau de sa zone de raccordement à l'alésage 18. Le clapet 16 est maintenu dans sa position des figures 2 à 4 par une goupille 34 solidaire de l'anneau 8 visible à la figure 1. Cette goupille, qui peut être réalisée en métal ou en matière plastique telle qu'en polyamide, est prévue pour traverser de part en part l'alésage 18 selon une direction Y2-Y2' et également perpendiculaire à l'axe X-X'.In the position of FIGS. 2 to 4, the valve 16 closes the bore 18 at the seat 20 and the bore 30 at its connection zone with the bore 18. The valve 16 is held in its position in FIGS. 2 to 4 by a pin 34 secured to the ring 8 visible in Figure 1. This pin, which can be made of metal or plastic such as polyamide, is intended to pass right through the bore 18 according to a direction Y 2 -Y 2 'and also perpendicular to the axis X-X'.

Le corps 12 est équipé d'un bouchon 36, alors que la douille 12b du corps 12 dans laquelle est ménagé l'alésage 18 est pourvue de deux encoches 12c et 12d qui ne sont pas complètement obturées lorsque le bouchon 36 est vissé en partie supérieure de la douille 12b. Il est ainsi possible d'insérer la goupille 34 dans le sens de la flèche F à la figure 3. Dans cette position, la goupille 36 bloque le clapet 16 dans une position de fermeture du robinet.The body 12 is equipped with a plug 36, while the socket 12 b of the body 12 in which the bore 18 is formed is provided with two notches 12 c and 12 d which are not completely closed when the plug 36 is screwed in the upper part of the socket 12 b . It is thus possible to insert the pin 34 in the direction of the arrow F in FIG. 3. In this position, the pin 36 blocks the valve 16 in a position for closing the valve.

Afin de positionner, avec une précision acceptable, la goupille 34 par rapport au clapet et au corps 12, la face 38 du clapet 16 opposée au réservoir 2 est équipée d'un pion 40 au niveau de sa partie centrale, c'est-à-dire au niveau de l'axe X-X'. Par ailleurs, la goupille 34 est équipée d'un logement 42 de réception de l'extrémité du pion 40. Ainsi, la coopération des éléments 40 et 42 résulte dans la création d'un point dur lors de l'introduction de la goupille 34 dans l'alésage 18, ce qui permet à un opérateur de détecter le bon positionnement de la goupille par rapport au clapet. Ce point dur diminue également les risques de déplacement intempestif de la goupille lorsque celle-ci est en place, c'est-à-dire de déverrouillage inopiné du robinet 10. Par ailleurs, la goupille 34 possède une face en biseau 44 qui facilite son introduction, dans le sens de la flèche F, car son extrémité avant est fine, alors que son extraction dans le sens opposé à la flèche F est également facilitée car l'effet exercé par la clapet 16 tend à chasser la goupille.In order to position, with acceptable precision, the pin 34 relative to the valve and to the body 12, the face 38 of the valve 16 opposite the tank 2 is equipped with a pin 40 at the level of its central part, that is to say at the level of the axis XX '. Furthermore, the pin 34 is equipped with a housing 42 for receiving the end of the pin 40. Thus, the cooperation of elements 40 and 42 results in creation of a hard point when introducing the pin 34 in bore 18, which allows an operator to detect the correct positioning of the pin relative to the valve. This point hard also reduces the risk of accidental displacement of the pin when it is in place, i.e. unexpected release of valve 10. In addition, the pin 34 has a bevelled face 44 which facilitates its introduction, in the direction of arrow F, because its end front is fine, while its extraction in the opposite direction arrow F is also facilitated because the effect exerted by the valve 16 tends to drive out the pin.

Le bouchon 36 porte, sur sa face interne dirigée vers l'alésage 18, un logement 46 de réception du pion 40 en position ouverte du robinet, comme cela ressort de la figure 5.The plug 36 carries, on its internal face directed towards the bore 18, a housing 46 for receiving the pin 40 in open position of the tap, as shown in the figure 5.

Selon une variante non représentée de l'invention, la face 38 du clapet 16 peut ne pas porter de pion du type du pion 40, la goupille étant alors maintenue en place uniquement grâce à la pression exercée par le clapet.According to a variant not shown of the invention, the face 38 of valve 16 may not bear a pin of the type of pin 40, the pin then being held in place only thanks to the pressure exerted by the valve.

L'alésage 18 forme un épaulement interne 48 alors que le clapet 16 possède, au niveau de sa face arrière 38, une base 50 de diamètre supérieur à sa partie principale 24, de telle sorte qu'il est créé un épaulement externe 52 sur le clapet 16. Un ressort 54 est disposé, entre les épaulements 48 et 52, à l'intérieur de l'alésage 18, autour de la partie principale 24 du clapet 16. Ce ressort charge élastiquement le clapet 16 dans une direction d'éloignement du siège 20, c'est-à-dire dans une direction d'éloignement par rapport au réservoir 2, ce qui correspond à l'ouverture du robinet 10.The bore 18 forms an internal shoulder 48 while the valve 16 has, at its rear face 38, a base 50 of diameter greater than its main part 24, such so that an external shoulder 52 is created on the valve 16. A spring 54 is arranged, between the shoulders 48 and 52, inside bore 18, around the main part 24 of the valve 16. This spring resiliently loads the valve 16 in a direction away from the seat 20, that is to say in a direction away from the reservoir 2, which corresponds to the opening of tap 10.

Le fonctionnement est le suivant :The operation is as follows:

Lorsqu'il est nécessaire de se servir de l'extincteur 1, l'utilisateur tire sur l'anneau 8 afin de le séparer de la coiffe 4, de telle sorte que la goupille 34 est extraite de l'alésage 18, par un déplacement dans le sens inverse de la flèche F de la figure 3. L'effort combiné de la pression s'exerçant sur la tête 22 et de la force de compression du ressort 54 a pour effet de repousser le clapet 16 contre le bouchon 36, libérant ainsi un passage entre le tube plongeur 14 et le perçage 30, ce passage permettant la circulation du fluide de traitement d'incendie jusque vers la tête de décharge 7. Le robinet est alors dans la position ouverte de la figure 5.When it is necessary to use extinguisher 1, the user pulls on the ring 8 in order to separate it from the cap 4, so that the pin 34 is extracted from the bore 18, by a movement in the opposite direction of the arrow F in figure 3. The combined force of pressure exerted on the head 22 and the compression force of the spring 54 has the effect of pushing the valve 16 against the plug 36, thus freeing a passage between the dip tube 14 and the bore 30, this passage allowing the circulation of the fire treatment fluid to the head of discharge 7. The valve is then in the open position of Figure 5.

Le déplacement du clapet 16 de sa position des figures 2 à 4 à sa position de la figure 5 est réalisé automatiquement dès que la goupille 34 est retirée et sans intervention de leviers et/ou d'organes de verrouillage. En d'autres termes, l'ouverture du robinet 10 a lieu directement, dès le retrait de la goupille 34.The displacement of the valve 16 from its position in the figures 2 to 4 at its position in Figure 5 is performed automatically as soon as the pin 34 is removed and without intervention of levers and / or locking devices. In other words, tap 10 is opened directly upon removal of the pin 34.

En outre, la mise sous pression du tuyau flexible 6 qui résulte de l'ouverture du robinet 10 a lieu sans manipulation de la tête 7, de sorte que la séquence de mise en oeuvre de l'extincteur est particulièrement simple et logique pour un utilisateur, même paniqué :

  • il dégoupille le robinet 10 ;
  • il prend en main la tête 7 pour la diriger vers les flammes et il contrôle le jet de fluide de traitement au moyen du levier 7b.
In addition, the pressurization of the flexible hose 6 which results from the opening of the valve 10 takes place without manipulation of the head 7, so that the sequence of implementation of the extinguisher is particularly simple and logical for a user. , even panicked:
  • he pins the tap 10;
  • he takes the head 7 in hand to direct it towards the flames and he controls the jet of treatment fluid by means of the lever 7 b .

L'anneau 8 et la goupille 34 peuvent être solidarisés après le montage du robinet 10 sur le réservoir 2 et la mise en place de la coiffe 4.Ring 8 and pin 34 can be secured after mounting the valve 10 on the tank 2 and putting in place of the cap 4.

Un indicateur de pression 60 est monté sur un piquage 62 du corps 12 en communication avec le volume intérieur du réservoir 2 afin de connaítre en permanence la pression régnant à l'intérieur de ce réservoir. Un raccord 64 muni d'une valve 66 permet d'alimenter, à travers un filtre 68, le volume intérieur du réservoir 2 en fluide de pressurisation.A pressure indicator 60 is mounted on a nozzle 62 of the body 12 in communication with the interior volume of the tank 2 in order to constantly know the pressure prevailing inside this tank. A fitting 64 provided a valve 66 makes it possible to feed, through a filter 68, the internal volume of the reservoir 2 in pressurization fluid.

Compte tenu de ce qui précède, il est possible de monter le robinet 10 sur le réservoir 2 alors que la goupille 34 est en place dans l'alésage 18 et que le clapet 16 est maintenu en position fermée. On procède alors à la mise en pression du réservoir 2, à travers la valve 66, ce qui peut être contrôlé grâce à l'indicateur de pression 60. Il est ensuite possible de monter la coiffe 4 autour du robinet 10 en partie supérieure du réservoir 2 et de solidariser la goupille 34 et l'anneau 8 par tout moyen approprié, alors que la coiffe 4 laisse apparaítre l'indicateur de pression 60, comme représenté à la figure 1. La pose d'un scellé, dont la rupture permet de détecter un déplacement de la goupille 34 peut être effectué avant mise en place de la coiffe 4, un tel scellé étant ensuite protégé par la coiffe.In view of the above, it is possible to climb the valve 10 on the tank 2 while the pin 34 is in place in bore 18 and that valve 16 is held in the closed position. We then pressurize the tank 2, through valve 66, which can be controlled thanks to the pressure indicator 60. It is then possible mount the cover 4 around the tap 10 at the top of the reservoir 2 and securing the pin 34 and the ring 8 by any appropriate means, while the cap 4 reveals the pressure indicator 60, as shown in Figure 1. The installation of a seal, the breaking of which can detect a displacement of the pin 34 can be carried out before fitting the cap 4, such a seal then being protected by the cap.

De la même manière, lors des intervention de maintenance sur l'extincteur de l'invention, il est possible d'ouvrir la coiffe 4 pour accéder au robinet 10, notamment à son raccord de mise en pression 64.Similarly, during maintenance interventions on the fire extinguisher of the invention, it is possible to open the cover 4 to access the tap 10, in particular to its connection pressurization 64.

L'invention a été présentée avec un robinet 10 protégé par une coiffe et relié à un tube flexible. Elle est cependant applicable indépendamment d'une telle coiffe 4 et, notamment, dans le cas d'un robinet relié directement à une buse de projection branchée directement sur son orifice de sortie, comme représenté aux figures 6 et 7, où les éléments analogues à ceux du mode de réalisation des figures 1 à 5 portent des références identiques. Une bague 101 permet de visser le robinet 10 sur un filet externe 102 de l'orifice 2a du réservoir 2. Le corps 12 du robinet 10 se prolonge par une poignée 103 sur un côté alors qu'il porte, sur le côté opposé, une buse 104 de pulvérisation du produit contenu dans le réservoir. La buse 104 est reliée au volume intérieur du corps 12 par un conduit 30 de sortie du fluide de traitement d'incendie. Un clapet 16 est logé dans un alésage 18 du corps 12 et fonctionne comme indiqué en référence au premier mode de réalisation, le clapet étant représenté en position fermée du robinet 10 sur la gauche de la figure 7 et en position ouverte sur la droite de cette figure. Le mouvement de recul du clapet dans le corps 12 dans un sens d'éloignement par rapport au réservoir est limité par un bouchon 36. Une goupille 34 peut bloquer ce mouvement par insertion dans des encoches du corps 12, dont une seule est visible avec la référence 12c. Un indicateur de pression 60 est raccordé sur un piquage 62 du corps 12.The invention has been presented with a tap 10 protected by a cap and connected to a flexible tube. It is however applicable independently of such a cap 4 and, in particular, in the case of a tap connected directly to a projection nozzle connected directly to its outlet orifice, as shown in FIGS. 6 and 7, where the elements similar to those of the embodiment of FIGS. 1 to 5 bear identical references. A ring 101 makes it possible to screw the tap 10 onto an external thread 102 of the orifice 2 a of the reservoir 2. The body 12 of the tap 10 is extended by a handle 103 on one side while it carries, on the opposite side, a nozzle 104 for spraying the product contained in the tank. The nozzle 104 is connected to the interior volume of the body 12 by a conduit 30 for the outlet of the fire treatment fluid. A valve 16 is housed in a bore 18 of the body 12 and operates as indicated with reference to the first embodiment, the valve being shown in the closed position of the valve 10 on the left of FIG. 7 and in the open position on the right of this figure. The recoil movement of the valve in the body 12 in a direction away from the reservoir is limited by a plug 36. A pin 34 can block this movement by insertion in the notches of the body 12, only one of which is visible with the reference 12 c . A pressure indicator 60 is connected to a nozzle 62 of the body 12.

Le clapet 16 est équipé de deux joints toriques 128a et 128b destinés à venir en appui respectivement contre deux parties 118a et 118b de la surface radiale de l'alésage 18 qui sont de diamètres différents. Les joints 128a et 128b constituent ainsi des segments d'étanchéité entre le clapet 16 et l'alésage 18. Un épaulement 48 prévu, dans le corps 12, entre les surfaces 118a et 118b coopère avec un épaulement correspondant 148 prévu sur le clapet 16.The valve 16 is equipped with two O-rings 128 a and 128 b intended to bear respectively against two parts 118 a and 118 b of the radial surface of the bore 18 which are of different diameters. The seals 128 a and 128 b thus constitute sealing segments between the valve 16 and the bore 18. A shoulder 48 provided, in the body 12, between the surfaces 118 a and 118 b cooperates with a corresponding shoulder 148 provided on the valve 16.

Aucun ressort n'est prévu pour charger élastiquement le clapet 16 en direction du bouchon 36 car la pression régnant dans le réservoir 2 est suffisante pour pousser le piston en position d'ouverture du robinet, telle que représentée sur la droite de la figure 7, dès que la goupille 34 a été retirée.No spring is provided to elastically load the valve 16 in the direction of the plug 36 because the pressure prevailing in tank 2 is sufficient to push the piston in valve opening position, as shown in the right of Figure 7, as soon as the pin 34 has been removed.

Le couvercle 36 porte un pion central 136 autour duquel est immobilisée, par coopération de formes, une bague élastique 137 en élastomère ou équivalent qui permet d'amortir l'impact du clapet 16 contre le bouchon 36 lors de son passage de sa position fermée à sa position ouverte.The cover 36 carries a central pin 136 around which is immobilized, by cooperation of forms, a ring elastic 137 made of elastomer or equivalent which allows cushioning the impact of the valve 16 against the plug 36 during its passage from its closed position to its open position.

Selon une variante non représentée de ce second mode de réalisation de l'invention, la poignée 103 peut être amovible par rapport au corps 12.According to a variant not shown of this second mode of embodiment of the invention, the handle 103 can be removable relative to the body 12.

Quel que soit le mode de réalisation considéré, le corps 12 peut être en métal, notamment en laiton, ou en matière plastique alors que le clapet peut également être en métal ou en matière plastique, notamment en polyamide chargé de fibres de renfort.Whatever the embodiment considered, the body 12 may be made of metal, in particular brass, or of material plastic while the valve can also be made of metal or made of plastic, especially of polyamide filled with fibers reinforcement.

Dans le premier mode de réalisation, l'invention a été représentée avec un tube plongeur 14, elle est cependant applicable en l'absence d'un tel tube plongeur, notamment lorsque l'extincteur est prévu pour être utilisé "tête en bas".In the first embodiment, the invention was shown with a dip tube 14, it is however applicable in the absence of such a dip tube, in particular when the extinguisher is intended to be used "head on low".
