Abstract
Description
L'invention vise à assurer une meilleure diffusion de l'agent extincteur et, dans ce but, elle prévoit, dans un extincteur en forme de bouteille à fond concave, de monter, dans un orifice de sortie du gaz ménagé au centre du fond, un obturateur logé dans un boîtier étanche au gaz, dont la paroi comporte une pluralité de trous d'axes sensiblement orthogonaux à l'axe du dit orifice et répartis radialement autour de cet axe à un niveau tel que les dits axes des trous rencontrent la paroi concave du fond de l'extincteur, des moyens étant prévus pour déplacer l'obturateur dans le sens de ltouver- ture du dit orifice. The invention aims to ensure better diffusion of the extinguishing agent and, for this purpose, it provides, in a bottle-shaped fire extinguisher with concave bottom, to mount, in a gas outlet orifice formed in the center of the bottom, a shutter housed in a gas-tight housing, the wall of which comprises a plurality of axis holes substantially orthogonal to the axis of said orifice and distributed radially around this axis at a level such that said axes of holes meet the wall concave of the bottom of the fire extinguisher, means being provided for moving the shutter in the direction of opening of said orifice.
On voit qu'au moment de l'ouverture, l'agent extincteur pénètre dans le boîtier et en sort par les trous de sa paroi sous forme de jets radiaux qui viennent frapper la paroi du fond concave de l'extincteur et sont réfléchis par cette paroi. We see that at the time of opening, the extinguishing agent enters the housing and leaves it through the holes in its wall in the form of radial jets which strike the wall of the concave bottom of the extinguisher and are reflected by this wall.
Il en résulte la formation d'un cône dont l'ouverture angulaire dépend de la forme du fond de l'extincteur et du niveau des trous du boîtier Grace à la turbulence créée dans le fond de l'extincteur, on obtient une excellente diffusion de l'agent extincteur
Les moyens de déplacement de l'obturateur peuvent être des moyens mécaniques ou pyrotechniques, fonctionnant manuellement > automatiquement ou telecommandes
A titre nullement limitatif, on a représenté au dessin annexé un exemple de réalisation d'extincteur selon l'invention, dessin dont la figure-unique est une vue en coupe axiale de la partie inférieure de l'extincteur.This results in the formation of a cone, the angular opening of which depends on the shape of the bottom of the extinguisher and the level of the holes in the housing. Thanks to the turbulence created in the bottom of the extinguisher, excellent diffusion is obtained. extinguishing agent
The displacement means of the shutter can be mechanical or pyrotechnic means, operating manually> automatically or by remote control
By way of non-limiting example, there is shown in the accompanying drawing an embodiment of a fire extinguisher according to the invention, a drawing of which the single figure is a view in axial section of the lower part of the fire extinguisher.
Dans l'exemple représenté, c'est un obturateur à ouverture pyrotechnique, commandé électriquement, qui est monté dans l'orifice (7) central du fond concave (8) de la bouteille (9) contenant le gaz extincteur. In the example shown, it is a shutter with electrically controlled pyrotechnic opening, which is mounted in the central orifice (7) of the concave bottom (8) of the bottle (9) containing the extinguishing gas.
L'obturateur comporte un clapet (6) en appui contre un siège (10) prévu dans le corps, ou bortier, (1) de l'obturateur. Cette soupape repose sur une entretoise cylindrique en verre (5),portée elle-même par le bouchon (3). Dans ce cylindre entretoise (5),est logé un allumeur (2) actionnable électriquement et reposant sur un porte allumeur (4). La paroi du bottier (1) est percée de trous radiaux (il, 11') dont les axes sont situés dans un plan de niveau légèrement supérieur à celui de la base de la bouteille (9). The shutter comprises a valve (6) bearing against a seat (10) provided in the body, or bortier, (1) of the shutter. This valve rests on a cylindrical glass spacer (5), itself carried by the plug (3). In this spacer cylinder (5), is housed an electrically actuable igniter (2) resting on an igniter holder (4). The wall of the shoemaker (1) is pierced with radial holes (11, 11 ') whose axes are located in a plane of level slightly higher than that of the base of the bottle (9).
Lorsqu'on commande l'allumage de l'allumeur (2), on provoque la rupture de l'entretoise (5). La soupape (6), soumis à la pression du gaz, est projeté vers le bas et le gaz sort alors par les trous (11, Il'). Ces jets radiaux frappent la paroli (8) du fond et sont réflechis vers le bas. De ce fait, et sous l'action de la turbulence dans ce fond (8), le jet de gaz extincteur se développe sous forme d'un c8ne,d'ouverture 60 environ, permettant, par cette bonne diffusion,l'extinction d'un foyer par inondation totale. When controlling the ignition of the igniter (2), the spacer (5) is broken. The valve (6), subjected to the pressure of the gas, is projected downwards and the gas then exits through the holes (11, II '). These radial jets strike the paroli (8) from the bottom and are reflected downwards. As a result, and under the action of turbulence in this bottom (8), the jet of extinguishing gas develops in the form of a cone, of aperture 60 approximately, allowing, by this good diffusion, the extinction of 'a home by total flooding.
Dans l'exemple décrits l'obturateur est de type pyrotechnique, mais il pourrait être d'un autre type, par exemple, d'un type similaire aux "sprinkler", c'est-à-dire dans lequel la soupape de l'obturateur s'ouvre automatiquement sous l'action d'une élévation locale de température, ou bien être mécanique à commande manuelle. In the example described, the shutter is of the pyrotechnic type, but it could be of another type, for example, of a type similar to "sprinklers", that is to say in which the valve of the shutter opens automatically under the action of a local temperature rise, or else be mechanical with manual control.
