VANNE D'ALIMENTATION D'UNE POMPE DE VEHICULE DE LUTTE
CONTRE L'INCENDIE
La présente invention concerne une vanne d'alimentation d'une pompe de véhicule de lutte contre l'incendie par exemple. Ce type de pompe présente la particularité d'être alimenté soit par une citerne embarquée sur le véhicule, soit, sur les lieux d'intervention, par une source extérieure.VALVE FOR SUPPLY OF A CONTROL VEHICLE PUMP
FIRE FIGHTING
The present invention relates to a supply valve of a fire fighting vehicle pump for example. This type of pump has the particularity of being supplied either by a tank on board the vehicle, or, at the intervention site, by an external source.
L'entrée de la pompe comporte une vanne trois voies qui permet de sélectionner soit la citerne, soit la source extérieure. The pump inlet has a three-way valve that allows you to select either the tank or the external source.
L'invention propose une vanne trois voies exclusive qui répond aux exigences de ce type d'application et, en particulier, présente l'avantage d'être particuliérement compacte. The invention proposes an exclusive three-way valve which meets the requirements of this type of application and, in particular, has the advantage of being particularly compact.
La vanne selon l'invention comporte un corps muni d'un premier orifice communiquant avec la tubulure d'aspiration de la pompe, un second orifice relié à une citerne installée sur le véhicule, et un troisième orifice relié à une source d'alimentation extérieure, lequel corps renferme un boisseau qui tourne autour d'un axe, lequel boisseau est muni d'un canal centré sur ledit axe et d'un orifice périphérique radial débouchant dans ledit canal, ce dernier orifice étant en relation avec l'orifice du corps relié à la citerne, lequel boisseau renferme dans son canal axial, en amont dudit orifice périphérique radial, un papillon monté sur un axe qui est perpendiculaire à celui dudit canal, lequel axe est guidé dans ledit boisseau et se prolonge à l'extérieur du corps pour permettre à la fois la manoeuvre dudit boisseau et celle dudit papillon, lequel axe est muni de moyens faisant office de butées, lesquels moyens sont guidés dans une lumière aménagée sur ledit corps de façon à permettre soit l'ouverture de l'orifice communiquant avec la citerne, par rotation du boisseau, soit l'ouverture de l'orifice relié à l'alimentation externe, par rotation dudit papillon. The valve according to the invention comprises a body provided with a first orifice communicating with the suction pipe of the pump, a second orifice connected to a tank installed on the vehicle, and a third orifice connected to an external power source , which body contains a plug which rotates about an axis, which plug is provided with a channel centered on said axis and with a radial peripheral orifice opening into said channel, this latter orifice being in relation to the orifice of the body connected to the tank, which plug contains in its axial channel, upstream of said radial peripheral orifice, a butterfly mounted on an axis which is perpendicular to that of said channel, which axis is guided in said plug and extends outside the body to allow both the operation of said plug and that of said butterfly, which axis is provided with means acting as stops, which means are guided in a light arranged on said horn ps so as to allow either the opening of the orifice communicating with the tank, by rotation of the plug, or the opening of the orifice connected to the external supply, by rotation of said butterfly.
Selon une disposition préférentielle de l'invention, le boisseau se présente sous la forme d'un tube centré sur l'axe d'entrée de la pompe, et guidé de façon étanche dans le corps de la vanne. Ce boisseau comporte un orifice périphérique radial dont le diamétre est inférieur de 25 à 30 % à celui de son canal cylindrique interne. According to a preferred arrangement of the invention, the plug is in the form of a tube centered on the inlet axis of the pump, and guided in sealed manner in the body of the valve. This plug has a radial peripheral orifice whose diameter is 25 to 30% smaller than that of its internal cylindrical channel.
Toujours selon l'invention, la lumière aménagée sur le corps de la vanne est centrée sur un plan radial par rapport à l'axe du boisseau, pour permettre la manoeuvre de ce dernier entre sa position ouverte et sa position fermée, les parois latérales de ladite lumière servant de guides aux moyens faisant office de butées, qui se présentent sous la forme d'une came solidaire de l'axe qui porte le papillon, laquelle came maintient ce dernier en position fermée lorsqu'elle est engagée dans la lumière, laquelle lumière comporte à l'une de ses extrémités qui correspond à la position de fermeture du boisseau, un aménagement qui permet de libérer ladite came de façon à autoriser la rotation dudit papillon pour le faire passer de la position fermée à la position ouverte selon les besoins. Still according to the invention, the light arranged on the valve body is centered on a radial plane relative to the axis of the plug, to allow the maneuver of the latter between its open position and its closed position, the side walls of said light serving as guides to the means acting as stops, which are in the form of a cam integral with the axis which carries the butterfly, which cam keeps the latter in the closed position when it is engaged in the light, which light comprises at one of its ends which corresponds to the closed position of the plug, a arrangement which makes it possible to release said cam so as to allow the rotation of said throttle to move it from the closed position to the open position as required .
Toujours selon l'invention, la came se présente sous la forme d'un levier qui s'étend dans un secteur en forme de quart de cercle aménagé à l'une des extrémités de la lumière. De préférence ce levier s'étend symétriquement de part et d'autre de l'axe du papillon et comporte à chacune de ses extrémités, un roulement en contact avec les parois guides de la lumière. Still according to the invention, the cam is in the form of a lever which extends in a sector in the form of a quarter of a circle arranged at one of the ends of the lumen. Preferably, this lever extends symmetrically on either side of the axis of the butterfly and comprises at each of its ends, a bearing in contact with the light guide walls.
L'invention sera encore détaillée à l'aide de la description suivante et des dessins annexés, donnés à titre indicatif, et dans lesquels: - la figure 1 est une vue schématique montrant une pompe sur laquelle est greffée une vanne trois voies selon l'invention, représentée en coupe - la figure 2 représente schématiquement et à plat, la lumière aménagée sur le corps cylindrique de la vanne; - la figure 3 représente la came qui permet de verrouiller le papillon dans sa position fermée. The invention will be further detailed with the aid of the following description and of the appended drawings, given for information only, and in which: - Figure 1 is a schematic view showing a pump on which is grafted a three-way valve according to the invention, shown in section - Figure 2 shows schematically and flat, the light provided on the cylindrical body of the valve; - Figure 3 shows the cam which allows to lock the butterfly in its closed position.
La pompe 1 représentée figure 1, comporte un orifice d'entrée 2 centré sur un axe 3. La vanne trois voies 4 comporte un corps 5 dont un premier orifice 6 est mis en communication avec l'entrée 2 de la pompe, lequel corps 5 est fixé directement sur l'orifice 2. Le corps 5 comporte un second orifice 7 qui est raccordé au moyen d'une tubulure 9 à une citerne 10 qui est par exemple installée sur le châssis, non représenté, d'un véhicule de lutte contre l'incendie par exemple. The pump 1 shown in FIG. 1 has an inlet port 2 centered on an axis 3. The three-way valve 4 comprises a body 5, a first port 6 of which is placed in communication with the inlet 2 of the pump, which body 5 is fixed directly to the orifice 2. The body 5 has a second orifice 7 which is connected by means of a tube 9 to a tank 10 which is for example installed on the chassis, not shown, of a vehicle for fighting against fire for example.
Le corps 5 comporte un troisième orifice 11. Cet orifice 11 est centré sur l'axe 3, dans le prolongement de l'orifice 6, alors que l'orifice 7 est disposé perpendiculairement à l'axe 3. The body 5 has a third orifice 11. This orifice 11 is centered on the axis 3, in the extension of the orifice 6, while the orifice 7 is arranged perpendicular to the axis 3.
L'orifice 11 reçoit une tubulure 12 qui est elle-même reliée à une source d'alimentation externe non représentée comme un cours d'eau, un étang ou encore un réseau d'eau prévu à cet effet. The orifice 11 receives a tube 12 which is itself connected to an external power source not shown as a stream, a pond or even a water network provided for this purpose.
Le corps 5 présente donc une forme cylindrique et il comporte une cavité interne dans laquelle est logé un boisseau 13. Ce boisseau 13, de forme tubulaire, peut tourner dans le corps 5; il est centré sur l'axe 3 c'est-à-dire l'axe longitudinal du corps 5. Ce boisseau 13 comporte un canal central 14 qui s'étend entre les orifices 6 et il du corps 5. Ce canal 14 a un diamètre qui correspond à celui de l'orifice 1 1 et il est centré sur l'axe 3. The body 5 therefore has a cylindrical shape and it has an internal cavity in which is housed a plug 13. This plug 13, of tubular shape, can rotate in the body 5; it is centered on the axis 3, that is to say the longitudinal axis of the body 5. This plug 13 has a central channel 14 which extends between the orifices 6 and it of the body 5. This channel 14 has a diameter which corresponds to that of the orifice 1 1 and it is centered on the axis 3.
Le boisseau 13 comporte un orifice périphérique 15 centré sur un axe radial, perpendiculaire à l'axe 3. Cet orifice 15 permet de mettre en communication l'orifice 7 avec le canal 14 et l'entrée de la pompe par l'orifice 6 du corps 5. The plug 13 has a peripheral orifice 15 centered on a radial axis, perpendicular to the axis 3. This orifice 15 makes it possible to put the orifice 7 in communication with the channel 14 and the inlet of the pump through the orifice 6 of the body 5.
Le diamètre de l'orifice 15 est inférieur à celui de l'orifice 11, de 25 à 30 % environ, par exemple. The diameter of the orifice 15 is less than that of the orifice 11, by 25 to 30% approximately, for example.
Entre l'orifice 11 et l'orifice 15, on remarque, logé dans le canal 14, un papillon 16 représenté en position fermée en traits forts et en position ouverte en traits mixtes fins. Ce papillon 16 est situé en amont de l'orifice 15 et de l'orifice 7. Il permet de fermer l'alimentation extérieure. Between the orifice 11 and the orifice 15, we note, housed in the channel 14, a butterfly 16 shown in the closed position in strong lines and in the open position in thin dashed lines. This butterfly 16 is located upstream of the orifice 15 and the orifice 7. It makes it possible to close the external supply.
Ce papillon 16 est monté sur un axe 17 qui est guidé dans le boisseau 13. Cet axe 17 est disposé perpendiculairement à l'axe longitudinal 3. Il traverse le corps 5 et il est guidé dans une lumière 19 qui apparaît plus clairement figure 2, laquelle lumière est aménagée dans la paroi dudit corps 5. This butterfly 16 is mounted on an axis 17 which is guided in the plug 13. This axis 17 is arranged perpendicular to the longitudinal axis 3. It passes through the body 5 and it is guided in a lumen 19 which appears more clearly in FIG. 2, which light is arranged in the wall of said body 5.
Cet axe 17 est manoeuvré au moyen d'un levier 20 qui fait office de manivelle pour faire pivoter le papillon 16 entre la position ouverte et la position fermée. This axis 17 is maneuvered by means of a lever 20 which acts as a crank to rotate the butterfly 16 between the open position and the closed position.
Cet axe 17 qui est guidé dans les alésages 21 et 22 du boisseau 13, sert également à la manoeuvre dudit boisseau par un mouvement de rotation autour de l'axe 3, lequel mouvement est autorisé par la lumière 19 qui s'étend dans un plan radial 23, perpendiculaire à l'axe 3, pour permettre l'ouverture et la fermeture dudit boisseau 13, c'est-à-dire le dégagement ou l'obturation de l'orifice 7 du corps 5. This axis 17 which is guided in the bores 21 and 22 of the plug 13, also serves for the operation of said plug by a rotational movement around the axis 3, which movement is authorized by the light 19 which extends in a plane radial 23, perpendicular to the axis 3, to allow the opening and closing of said plug 13, that is to say the opening or closing of the orifice 7 of the body 5.
Cette manoeuvre de l'axe 17 pour déplacer le boisseau 13, peut s'effectuer au moyen d'une poignée 24 disposée à l'extrémité de l'axe 17, associée par exemple au levier 20. This maneuver of the axis 17 to move the plug 13, can be carried out by means of a handle 24 disposed at the end of the axis 17, associated for example with the lever 20.
Pour obtenir une vanne trois voies de type exclusive, I'axe 17 comporte une butée en forme de came 26, laquelle came est guidée dans la glissière 19 et en particulier entre les parois 27 et 29 de ladite glissière, comme représenté figure 2. To obtain an exclusive type three-way valve, the axis 17 includes a cam-shaped stop 26, which cam is guided in the slide 19 and in particular between the walls 27 and 29 of said slide, as shown in FIG. 2.
Ainsi, comme représenté à la partie supérieure de la figure 2, I'axe 17 est positionné à une extrémité de la lumière 29 et la came 26 en forme de simple levier, s'étend longitudinalement dans la lumière 19, centrée sur l'axe 23. On remarque la position du levier 20, dans le prolongement de l'axe 23 de la lumière 19, laquelle position correspond à la position fermée du papillon 16 et à la position normale d'ouverture du boisseau 13 qui ouvre l'orifice 7 et met la citerne 10 en communication avec la pompe 1. Dans cette position, la poignée 24 qui sert à manoeuvrer la boisseau est perpendiculaire à l'axe 23. Thus, as shown in the upper part of FIG. 2, the axis 17 is positioned at one end of the lumen 29 and the cam 26 in the form of a single lever, extends longitudinally in the lumen 19, centered on the axis 23. Note the position of the lever 20, in the extension of the axis 23 of the light 19, which position corresponds to the closed position of the butterfly 16 and to the normal position of opening of the plug 13 which opens the orifice 7 and places the tank 10 in communication with the pump 1. In this position, the handle 24 which is used to maneuver the plug is perpendicular to the axis 23.
Cette poignée 24 permet par exemple de déplacer l'axe 17 pour l'amener dans la partie basse de la figure 2, à l'autre extrémité de la lumière 19.This handle 24 makes it possible, for example, to move the axis 17 to bring it into the lower part of FIG. 2, at the other end of the light 19.
Cette autre extrémité de la lumière 19 comporte un aménagement 30 en forme de secteur circulaire qui correspond à un quart de cercle. La came 26 peut être manoeuvrée pour passer d'une position parallèle à l'axe 23 de la lumière 19 à une position perpendiculaire comme représenté sur la figure 2, qui correspond à l'alignement de l'axe longitudinal 3 du corps et du boisseau 13 et dans cette position, le papillon 16 est ouvert. This other end of the light 19 has an arrangement 30 in the form of a circular sector which corresponds to a quarter of a circle. The cam 26 can be maneuvered to pass from a position parallel to the axis 23 of the light 19 to a perpendicular position as shown in FIG. 2, which corresponds to the alignment of the longitudinal axis 3 of the body and the plug 13 and in this position, the butterfly 16 is open.
La poignée 24 est positionnée dans l'alignement de l'axe 23 de la lumière 19. The handle 24 is positioned in alignment with the axis 23 of the light 19.
La figure 3 représente une variante de la came 26 qui comporte en fait deux leviers ou cames disposés de part et d'autre de l'axe 17. Les cames 26 et 26' comportent chacune à leurs extrémités, un roulement 32 qui est en contact avec les parois 27 et 29 de la lumière 19. Ces roulements 32 permettent une manoeuvre plus aisée du levier 17 pour faire passer le boisseau 13 de la position ouverte à la position fermée tout en maintenant le papillon 16 en position fermée. FIG. 3 represents a variant of the cam 26 which in fact comprises two levers or cams arranged on either side of the axis 17. The cams 26 and 26 ′ each have at their ends a bearing 32 which is in contact with the walls 27 and 29 of the light 19. These bearings 32 allow easier operation of the lever 17 to move the plug 13 from the open position to the closed position while keeping the butterfly 16 in the closed position.
Dans le cas d'une came avec deux branches 26 et 26', I'extrémité de la lumière comporte un aménagement 30' qui correspond à une symétrie de l'aménagement 30 par rapport à l'axe 17 lorsque cet axe est situé comme représenté figure 2 à l'extrémité de la lumière 19 dans le bas de ladite figure 2. In the case of a cam with two branches 26 and 26 ′, the end of the light has an arrangement 30 ′ which corresponds to a symmetry of the arrangement 30 with respect to the axis 17 when this axis is located as shown Figure 2 at the end of the light 19 at the bottom of said Figure 2.
