Description

La présente invention concerne une lance à incendie comportant un dispositif de sécurité pour l'empêcher de se déplacer sous l'action de l'eau assurant son alimentation.The present invention relates to a fire hose comprising a security device to prevent it from moving under the action of water ensuring its food.
Le document US-A-2002451 montre un dispositif de sécurité pour un tuyau d'alimentation en eau qui évacue une partie du fluide sous pression, et absorbe par-là les coups de bélier résultants de l'inertie du mouvement d'eau lorsque la valve d'alimentation en eau est brusquement fermée.Document US-A-2002451 shows a safety device for a water supply pipe which evacuates part of the fluid under pressure, and thereby absorbs the water hammers resulting from the inertia of the water movement when the water supply valve is abruptly closed.
Lorsque de l'eau sous pression entre brusquement ou circule par à-coups dans une lance à incendie, elle soumet à chaque fois cette dernière à des forces produisant des coups de bélier plus ou moins intenses.When pressurized water suddenly enters or circulates jerks in a fire hose, she submits each time this last to forces producing more or less water hammer intense.
Or, sous l'action de ces coups de bélier, la lance à incendie a tendance à se déplacer de façon désordonnée par rapport au sol, risquant de blesser les personnes ou d'endommager les objets se trouvant sur sa trajectoire.Now, under the action of these water hammers, the fire hose has tendency to move disordered to the ground, risk of hurting people or damaging objects finding on its trajectory.
La présente invention se propose plus particulièrement de remédier à ces inconvénients et, pour se faire, elle a pour objet une lance à incendie du type indiqué au premier paragraphe ci-dessus, cette lance à incendie étant caractérisée en ce que le dispositif de sécurité comprend un corps tubulaire destiné à être raccordé à un tuyau d'alimentation en eau, un papillon comprenant deux tourillons coaxiaux montés pivotants sur le corps tubulaire, sur un axe horizontal s'étendant perpendiculairement à la direction d'écoulement de l'eau, le papillon étant déplaçable à l'intérieur du corps tubulaire entre une position d'ouverture dans laquelle il autorise la circulation de l'eau et une position de fermeture dans laquelle il limite cette circulation, un levier de commande extérieur solidaire de l'un des tourillons, et un déclencheur porté par le levier de commande et s'appuyant contre le sol en maintenant le papillon dans sa position d'ouverture lorsque le levier de commande exerce sur lui, sous l'action de l'eau circulant sur le papillon, une force verticale dirigée vers le bas.The present invention is intended more particularly to remedy these drawbacks and, to do so, it has for its object a fire hose of the type indicated in the first paragraph above, this fire hose being characterized in that the safety device comprises a tubular body intended to be connected to a water supply pipe, a butterfly comprising two coaxial journals pivotally mounted on the tubular body, on a horizontal axis extending perpendicular to the direction water flow, the butterfly being movable inside the tubular body between an open position in which it allows the circulation of water and a closed position in which it limits this circulation, a control lever outside of one of the pins, and a trigger carried by the control lever and leaning against the ground by now the butterfly in its open position when the lever of control exerts on him, under the action of water flowing on the butterfly, a vertical force directed downwards.
Grâce à cet ensemble de dispositions, les risques pour que la lance à incendie conforme à l'invention se déplace par rapport au sol sous l'action de coups de bélier produits par l'eau sont totalement éliminés.Thanks to this set of provisions, the risks for the fire hose according to the invention moves relative to the soil under the action of water hammers are totally eliminated.
Dès que la lance se déplace par rapport au sol, que ce soit verticalement, horizontalement ou dans une autre direction, le levier de commande cesse en effet d'agir verticalement sur le déclencheur. Or, en l'absence de cette action, l'eau circulant dans le corps tubulaire déplace immédiatement le papillon de sa position d'ouverture à sa position de fermeture, ce qui a pour conséquence de réduire fortement le débit de l'eau et d'immobiliser ainsi la lance pratiquement instantanément.As soon as the spear moves in relation to the ground, whether vertically, horizontally or in another direction, the control lever ceases indeed to act vertically on the trigger. However, in the absence of this action, the water circulating the tubular body immediately moves the butterfly from its position opening at its closed position, which has the consequence of greatly reduce the flow of water and thus immobilize the lance almost instantly.
Selon un mode de réalisation particulier de l'invention, le corps tubulaire peut avoir une section transversale circulaire et être traversé, par exemple diamétralement, par l'axe de pivotement des tourillons.According to a particular embodiment of the invention, the tubular body can have a circular cross section and to be traversed, for example diametrically, by the pivot axis trunnions.
Avantageusement, la partie du papillon qui est en amont de l'axe de pivotement des tourillons, par rapport à la direction d'écoulement de l'eau, est dirigée vers le bas.Advantageously, the part of the butterfly which is upstream of the pivot axis of the trunnions, with respect to the direction flow of water, is directed downwards.
Comme la partie amont du papillon est inclinée vers le bas, l'eau possède une plus grande prise sur ce dernier et peut donc le déplacer rapidement de sa position d'ouverture à sa position de fermeture dès que le déclencheur n'est plus soumis à l'action d'une force verticale.As the upstream part of the butterfly is inclined downwards, the water has a bigger hold on it and so can the quickly move from its open position to its position of closing as soon as the trigger is no longer subject to the action of a vertical force.
De préférence, la lance à incendie conforme à l'invention comporte une butée qui, lorsque l'eau ne circule pas, maintient le papillon dans une position de repos dans laquelle le déclencheur est éloigné du sol.Preferably, the fire hose according to the invention has a stop which, when the water is not flowing, maintains the butterfly in a rest position in which the trigger is away from the ground.
Grâce à cette butée, le déclencheur demeure donc au-dessus du sol lorsque l'eau ne circule pas, et ne risque par conséquent pas d'être sali ou détérioré quand la lance n'est pas utilisée.With this stop, the trigger remains above the soil when the water is not flowing, and therefore does not risk to be dirty or deteriorated when the spear is not used.
La butée peut avantageusement être portée par la partie du papillon qui est en aval de l'axe de pivotement des tourillons, par rapport à la direction d'écoulement de l'eau, et s'appuyer contre la face interne du corps tubulaire pour maintenir le papillon dans sa position de repos.The stop may advantageously be carried by the part of the butterfly which is downstream of the pivot axis of the trunnions, by relative to the flow direction of the water, and lean against the inner face of the tubular body to hold the butterfly in its rest position.
Etant à l'intérieur même du corps de la lance, la butée est parfaitement protégée contre les risques de détérioration d'origine externe.Being inside the body of the spear, the stop is perfectly protected against the risk of deterioration of origin external.
Pour faciliter les opérations de fabrication et réduire le prix de revient de la lance à incendie, le levier de commande peut être pourvu d'un orifice parallèle à l'axe de pivotement des tourillons tandis que le déclencheur peut comporter une tige se terminant par un crochet enfilé dans l'orifice du levier de commande. To facilitate manufacturing operations and reduce the price of the fire hose, the control lever can be provided with an orifice parallel to the axis of pivoting of the journals while the trigger can include a rod ending in a hook threaded into the hole of the control lever.
La tige peut par ailleurs comporter à son extrémité opposée au crochet un embout prenant appui contre le sol lorsque le papillon est en position d'ouverture.The rod may further comprise at its end opposite the hook a tip taking support against the ground when the butterfly is in the open position.
Pour qu'un opérateur puisse facilement ramener le papillon dans sa position d'ouverture, le levier de commande peut avantageusement comprendre une poignée de manoeuvre à son extrémité opposée au déclencheur, la poignée de manoeuvre s'étendant alors vers le haut lorsque le papillon est dans sa position d'ouverture.For an operator to easily return the butterfly to its open position, the control lever can advantageously include a maneuvering handle at its opposite end to trigger, the maneuvering handle then extending upwards when the butterfly is in its open position.
Un mode d'exécution de la présente invention sera décrit ci-après à titre d'exemple nullement limitatif en référence aux dessins annexés dans lesquels :
  • la figure 1 est une vue de côté schématique d'une lance à incendie conforme à l'invention, cette lance étant fixée à l'extrémité libre d'un tuyau d'alimentation en eau ;
  • la figure 2 est une vue en bout, avec arrachement partiel, du dispositif de sécurité de la lance visible sur la figure 1 ;
  • la figure 3 est une vue de côté schématique du dispositif de sécurité, montrant le papillon dans sa position d'ouverture, l'eau circulant sans à-coup dans la lance à incendie ;
  • la figure 4 est une vue analogue à la figure 3, mais montrant le dispositif de sécurité après la production d'un coup de bélier par l'eau circulant dans la lance, celle-ci ayant reculé à partir de sa position d'origine représentée en traits mixtes ; et
  • la figure 5 est une vue analogue à la figure 3, mais montrant le dispositif de sécurité lorsque le papillon est dans sa position de fermeture, la position d'origine de la lance étant encore représentée en traits mixtes.
An embodiment of the present invention will be described hereinafter by way of non-limiting example with reference to the accompanying drawings in which:
  • Figure 1 is a schematic side view of a fire hose according to the invention, the lance being attached to the free end of a water supply pipe;
  • Figure 2 is an end view, partially broken away, of the safety device of the lance visible in Figure 1;
  • Figure 3 is a schematic side view of the safety device, showing the butterfly in its open position, the water smoothly flowing in the fire hose;
  • Figure 4 is a view similar to Figure 3, but showing the safety device after the production of a water hammer by the water circulating in the lance, the latter having moved back from its original position represented in phantom lines; and
  • Figure 5 is a view similar to Figure 3, but showing the safety device when the butterfly is in its closed position, the original position of the lance is still shown in phantom.
La lance à incendie que l'on peut voir sur la figure 1 se distingue des lances classiques uniquement par le dispositif de sécurité 1 qui est prévu à son entrée et par l'intermédiaire duquel elle est reliée à un tuyau d'alimentation en eau 2.The fire hose that can be seen in Figure 1 is distinguished from conventional lances only by the device of security 1 which is provided at its entry and through which it is connected to a water supply pipe 2.
Le dispositif de sécurité 1 comprend un corps tubulaire 3 relié au tuyau 2 par un raccord conventionnel 4, ce raccord étant constitué de deux éléments complémentaires portés respectivement par le corps tubulaire 3 et le tuyau 2.The safety device 1 comprises a tubular body 3 connected to the pipe 2 by a conventional connector 4, this connection being consisting of two complementary elements carried respectively by the tubular body 3 and the pipe 2.
Le corps tubulaire 3 renferme un papillon 5 déplaçable entre une position d'ouverture (visible sur la figure 3) dans laquelle il autorise la circulation de l'eau et une position de fermeture (visible sur la figure 5) dans laquelle il limite cette circulation.The tubular body 3 encloses a movable butterfly 5 between an open position (visible in FIG. 3) in which it allows the circulation of water and a closed position (visible in Figure 5) in which it limits this circulation.
Le papillon 5 est porté par deux tourillons coaxiaux 6 montés pivotants sur le corps tubulaire 3, sur un axe horizontal s'étendant perpendiculairement à la direction d'écoulement de l'eau.The butterfly 5 is carried by two coaxial journals 6 mounted pivoting on the tubular body 3, on a horizontal axis extending perpendicular to the direction of flow of the water.
Dans le mode de réalisation représenté sur les dessins, le corps tubulaire 3 a une section transversale circulaire et est traversé diamétralement par l'axe de pivotement des tourillons 6, comme le montre clairement la figure 2.In the embodiment shown in the drawings, the tubular body 3 has a circular cross section and is traversed diametrically by the pivot axis of the journals 6, as clearly shown in Figure 2.
Il va de soi cependant que l'on ne sortirait pas du cadre de la présente invention si la section transversale du corps tubulaire 3 avait une autre forme et/ou si l'axe de pivotement des tourillons 6 n'était pas diamétral.It goes without saying, however, that we would not go beyond the scope of present invention if the cross section of the tubular body 3 had another shape and / or if the pivot axis of the trunnions 6 was not diametrical.
Le dispositif de sécurité 1 comprend par ailleurs un levier de commande extérieur 7 solidaire de l'un des tourillons 6, et un déclencheur 8 porté par le levier 7 et dont la fonction sera décrite ci-après.The safety device 1 also comprises a lever of external control 7 secured to one of the pins 6, and a trigger 8 carried by the lever 7 and whose function will be described below.
En se reportant plus particulièrement aux figures 3 à 5, on remarquera que la partie 5a du papillon qui est en amont de l'axe de pivotement des tourillons 6, par rapport à la direction d'écoulement de l'eau, est dirigée vers le bas.Referring more particularly to FIGS. note that the part 5a of the butterfly which is upstream of the axis of pivoting of the journals 6, with respect to the direction of flow water, is directed down.
On remarquera également que la partie aval 5b du papillon porte sur sa face inférieure une butée 9 constituée par une tige cylindrique s'appuyant contre la face interne du corps tubulaire 3 lorsque la lance n'est pas alimentée en eau.It will also be noted that the downstream portion 5b of the butterfly on its underside a stop 9 constituted by a rod cylindrical bearing against the inner face of the tubular body 3 when the lance is not supplied with water.
Dans cette situation parfaitement visible sur la figure 2, la butée 9 maintient le papillon 5 dans une position de repos dans laquelle le déclencheur 8 est maintenu légèrement au-dessus du sol.In this perfectly visible situation in FIG. stop 9 keeps the butterfly 5 in a rest position in which trigger 8 is held slightly above the ground.
Comme cela ressort de la figure 3, le déclencheur 8 a pour fonction de maintenir le papillon 5 dans sa position d'ouverture lorsque le levier de commande 7 exerce sur lui, sous l'action de l'eau circulant sur la partie amont 5a du papillon, une force verticale le pressant contre le sol.As is apparent from Figure 3, the trigger 8 has for function to keep the butterfly 5 in its open position when the control lever 7 exerts on it, under the action of the water circulating on the upstream part 5a of the butterfly, a force vertical pressing it against the ground.
Il a également pour fonction de permettre au papillon de venir dans sa position de fermeture dès que l'eau circulant dans le corps tubulaire 3 produit un coup de bélier provoquant un déplacement de la lance à incendie par rapport au sol. It also serves to allow the butterfly to come in its closed position as soon as the water circulating in the body tubular 3 produces a water hammer causing a displacement of the fire hose from the ground.
A la suite de ce déplacement, le levier 7 cesse en effet d'exercer une force verticale sur le déclencheur 8. Or, comme celui-ci n'est plus en mesure de maintenir le papillon 5 dans sa position d'ouverture, l'eau contraint ce dernier à venir dans sa position de fermeture en exerçant sur sa partie amont 5a une pression dirigée vers le bas.As a result of this movement, the lever 7 ceases indeed to exert a vertical force on the trigger 8. Now, like this one no longer able to hold the butterfly 5 in its position opening, the water forces the latter to come into its position of closing by exerting on its upstream portion 5a a directed pressure down.
Dans le mode de réalisation représenté, le levier de commande 7 comporte à son extrémité la plus proche du sol un orifice 10 s'étendant parallèlement à l'axe de pivotement des tourillons 6.In the embodiment shown, the control lever 7 has at its end the closest to the ground an orifice 10 extending parallel to the pivot axis of the journals 6.
Quant au déclencheur 8, il comporte une tige 8a se terminant par un crochet 8b enfilé dans l'orifice 10, ainsi qu'un embout 8c vissé sur la tige 8a, du côté opposé au crochet 8b, et destiné à prendre appui contre le sol lorsque le papillon est en position d'ouverture.As for the trigger 8, it comprises a stem 8a ending by an 8b hook threaded into the orifice 10, and a tip 8c screwed on the rod 8a, on the side opposite the hook 8b, and intended to bear against the ground when the butterfly is in position opening.
Le déclencheur 8 pourrait bien entendu être différent de celui qui vient d'être décrit. Par exemple, un dispositif à rotule interposé entre le levier 7 et l'embout 8c pourrait remplacer la tige 8a sans que l'on sorte du cadre de la présente invention.The trigger 8 could of course be different from the one which has just been described. For example, a ball-and-socket device interposed between the lever 7 and the tip 8c could replace the 8a rod without departing from the scope of the present invention.
Enfin, on précisera que le levier de commande 7 comprend une poignée de manoeuvre 11 à son extrémité opposée au déclencheur 8, cette poignée s'étendant obliquement vers le haut lorsque le papillon 5 est dans sa position d'ouverture.Finally, it will be specified that the control lever 7 comprises a operating handle 11 at its end opposite the trigger 8, this handle extending obliquely upwards when the butterfly 5 is in its open position.
On va maintenant décrire succinctement le fonctionnement du dispositif de sécurité 1 de la lance à incendie conforme à l'invention, lorsque celui-ci est raccordé au tuyau d'alimentation 2 et que la lance à incendie repose sur le sol.We will now briefly describe the operation of the safety device 1 of the fire hose according to the invention, when it is connected to the supply pipe 2 and that the fire hose rests on the ground.
On positionne tout d'abord le papillon 5 dans sa position de repos en agissant sur la poignée 11 de telle sorte que la butée 9 vienne s'appuyer contre la face interne du corps tubulaire 3, comme représenté sur les figures 1 et 2.The butterfly 5 is first positioned in its position of rest by acting on the handle 11 so that the stop 9 come to bear against the inner face of the tubular body 3, as shown in Figures 1 and 2.
On ouvre ensuite la vanne (non représentée) reliant le tuyau 2 à la source d'alimentation en eau. Lorsque l'eau s'écoule sans à-coup dans le dispositif de sécurité 1, elle contraint le papillon 5 à venir dans sa position d'ouverture en le faisant pivoter dans le sens de la flèche représentée sur la figure 3. Une fois que le papillon est dans cette position, le levier de commande 7 applique le déclencheur 8 contre le sol en exerçant sur lui une force verticale dirigée vers le bas. Le papillon reste par conséquent dans sa position d'ouverture.The valve (not shown) connecting the pipe 2 is then opened at the source of water supply. When water flows smoothly in the safety device 1, it forces the butterfly 5 to come into its open position by rotating it in the direction of the arrow shown in Figure 3. Once the butterfly is in this position, the control lever 7 applies the trigger 8 against the ground by exerting on him a force vertical downward. The butterfly therefore remains in its open position.
Si maintenant le débit de l'eau varie brutalement au point que la lance à incendie soit contrainte de se déplacer par rapport au sol, le levier 7 cesse d'agir verticalement sur le déclencheur 8. Le papillon 5 n'étant plus retenu dans sa position d'ouverture, l'eau le fait immédiatement pivoter jusqu'à ce qu'il vienne dans sa position de fermeture représentée sur la figure 5.If now the flow of water varies suddenly to the point that the fire hose is forced to move relative to the the lever 7 stops acting vertically on the trigger 8. butterfly 5 is no longer held in its open position, the water immediately rotate it until it comes into closing position shown in Figure 5.
Une fois que la lance est immobilisée sur le sol, il suffit maintenant de saisir la poignée de manoeuvre 11 pour amener le papillon dans sa position de repos visible sur les figures 1 et 2. Lorsque cette opération est réalisée, l'eau qui circule dans le corps tubulaire 3 exerce alors sur la partie amont 5a du papillon une pression sous l'action de laquelle ce dernier vient dans sa position d'ouverture visible sur la figure 3.Once the spear is immobilized on the ground, it is sufficient now to grab the handle 11 to bring the butterfly in its rest position visible in Figures 1 and 2. When this operation is carried out, the water circulating in the tubular body 3 then exerts on the upstream portion 5a of the butterfly pressure under the action of which the latter comes into his opening position visible in Figure 3.
