Description

DOMAINE TECHNIQUE GENERAL ET ART ANTERIEURGENERAL TECHNICAL FIELD AND PRIOR ART

La présente invention concerne le domaine des réservoirs de liquide devant être vidangés, en particulier, un réservoir d'eau usée d'un véhicule ferroviaire.The present invention relates to the field of liquid tanks to be emptied, in particular, a waste water tank of a railway vehicle.

De manière connue, un véhicule ferroviaire pour le transport de passagers comporte des toilettes qui sont reliées, d'une part, à un réservoir d'eau neuve et, d'autre part, à un réservoir d'eau usée. Au fur et à mesure de l'utilisation des toilettes par les passagers du véhicule ferroviaire, le réservoir d'eau usée se remplit. Une fois le véhicule ferroviaire arrivé à sa destination finale, le réservoir doit être vidangé.In a known manner, a rail vehicle for the transport of passengers comprises toilets which are connected, on the one hand, to a new water reservoir and, on the other hand, to a wastewater reservoir. As the toilets are used by passengers of the railway vehicle, the waste water tank fills up. Once the rail vehicle has arrived at its final destination, the tank must be emptied.

En référence à la figure 1, il est représenté de manière schématique un dispositif de stockage d'eau usée 1 d'un véhicule ferroviaire, en particulier, pour les transports régionaux. Le dispositif de stockage 1 comporte un réservoir 2 qui est relié aux toilettes 3 par une canalisation d'entrée 23 et une vanne de vidange 4 qui est reliée au réservoir 2 par une canalisation de vidange 24. Lors de la vidange du réservoir 2, l'eau usée E doit être acheminée dans un récipient de stockage d'eau usée (non représenté) qui est connecté de manière fluidique à la vanne de vidange 4.With reference to the figure 1 it is schematically represented a waste water storage device 1 of a railway vehicle, in particular, for regional transport. The storage device 1 comprises a tank 2 which is connected to the toilet 3 by an inlet pipe 23 and a drain valve 4 which is connected to the tank 2 by a drain pipe 24. When the tank 2 is emptied, the tank 2 waste water E must be conveyed into a wastewater storage container (not shown) which is fluidly connected to the drain valve 4.

En pratique, le réservoir 2 est placé à une altitude plus élevée que celle des toilettes 3. Aussi, pour permettre à l'eau usée E des toilettes 3 de pénétrer dans le réservoir 2 via la canalisation d'entrée 23, le dispositif de stockage 1 comporte des moyens de dépression 5 configurés pour diminuer la pression d'air P2 dans le réservoir 2 afin d'aspirer l'eau usée E des toilettes 3 via la canalisation d'entrée 23. Les moyens de dépression 5 se présentent, par exemple, sous la forme d'un organe de tirage d'air connu de l'homme du métier qui est relié à la partie supérieure du réservoir 2 par une canalisation de dépression 25.In practice, the tank 2 is placed at a higher altitude than that of the toilet 3. Also, to allow the waste water E of the toilet 3 to enter the tank 2 via the inlet pipe 23, the storage device 1 comprises depression means 5 configured to reduce the air pressure P 2 in the tank 2 to suck up the wastewater E of the toilet 3 via the inlet pipe 23. The depression means 5 are, for example, example, in the form of an air draft member known to those skilled in the art which is connected to the upper part of the tank 2 by a vacuum pipe 25.

Pour permettre la vidange du réservoir 2, il est nécessaire de prévoir une vanne d'équilibrage de pression d'air 6 reliée audit réservoir 2 par une canalisation d'équilibrage 26. Cette vanne d'équilibrage 6 permet de relier le réservoir 2 à l'extérieur de manière à équilibrer la pression d'air P2 du réservoir 2 avec la pression atmosphérique Pext. Ainsi, il n'existe pas de risque que le réservoir 2 aspire l'eau usée du récipient de stockage lors d'une vidange. Comme illustré à la figure 2, le dispositif de stockage 1 comporte une manette de commande M configurée pour ouvrir simultanément la vanne de vidange 4 et la vanne d'équilibrage 6.To allow the tank 2 to be emptied, it is necessary to provide an air pressure equalizing valve 6 connected to said tank 2 by a balancing pipe 26. This balancing valve 6 makes it possible to connect the tank 2 to the tank 2. 'outside in order to balance the air pressure P 2 of the tank 2 with the atmospheric pressure P ext . Thus, there is no risk that the tank 2 sucks the waste water from the storage container during a drain. As illustrated in figure 2 , the storage device 1 comprises a control lever M configured to simultaneously open the drain valve 4 and the equilibration valve 6.

En pratique, au fur et à mesure de l'utilisation des toilettes 3 par les passagers du véhicule ferroviaire de transport, le réservoir 2 se remplit et son niveau augmente, ce qui augmente la pression d'air P2 à l'intérieur du réservoir 2. Si la pression d'air P4 à l'intérieur de la canalisation de vidange 24 est plus faible que la pression d'air P2 à l'intérieur du réservoir 2, de l'eau usée est aspirée par la canalisation de vidange 24 et vient en contact avec la vanne de vidange 4. Autrement dit, la canalisation de vidange 24 comporte un volume d'eau usée EP qui est piégé à proximité de la vanne de vidange 4 comme illustré à la figure 1.In practice, as and when the toilets 3 are used by the passengers of the railway transport vehicle, the tank 2 fills up and its level increases, which increases the air pressure P 2 inside the tank 2. If the air pressure P 4 inside the drain pipe 24 is lower than the air pressure P 2 inside the tank 2, waste water is sucked by the pipe of drain 24 and comes into contact with the drain valve 4. In other words, the drain pipe 24 comprises a waste water volume E P which is trapped near the drain valve 4 as shown in FIG. figure 1 .

La présence d'un tel volume d'eau usée EP n'est pas acceptable étant donné que lors d'opérations de maintenance, les opérateurs doivent ouvrir la vanne de vidange 4 sans pour autant réaliser une opération de vidange. Dans ce cas, le volume d'eau usée EP peut éclabousser les opérateurs qui sont alors salis.The presence of such a volume of waste water E P is not acceptable since during maintenance operations, operators must open the drain valve 4 without performing a drain operation. In this case, the volume of waste water E P can splash the operators who are then soiled.

Par ailleurs, le réservoir 2 est généralement placé à l'intérieur du véhicule ferroviaire et est donc protégé contre les conditions extérieures. A l'inverse, la vanne de vidange 4 est accessible depuis l'extérieur du véhicule ferroviaire et est sensible aux conditions extérieures. Aussi, le volume d'eau usée EP qui est piégé à proximité de la vanne de vidange 4 peut geler, ce qui peut entraîner une impossibilité de vidanger le réservoir ou un endommagement de la canalisation de vidange 24 et/ou de la vanne de vidange 4.Moreover, the tank 2 is generally placed inside the railway vehicle and is therefore protected against external conditions. Conversely, the drain valve 4 is accessible from outside the rail vehicle and is sensitive to external conditions. Also, the volume of waste water E P that is trapped near the drain valve 4 may freeze, which may result in an inability to drain the tank or damage to the drain pipe 24 and / or the valve. emptying 4.

Un des objectifs de la présente invention est de proposer un dispositif de stockage de liquide dont la fiabilité est améliorée.One of the objectives of the present invention is to provide a liquid storage device whose reliability is improved.

PRESENTATION GENERALE DE L'INVENTIONGENERAL PRESENTATION OF THE INVENTION

A cet effet, l'invention concerne un dispositif de stockage de liquide comportant un réservoir, une canalisation d'entrée reliée audit réservoir, des moyens de dépression configurés pour diminuer la pression d'air dans ledit réservoir afin d'aspirer du liquide via la canalisation d'entrée, une vanne de vidange reliée audit réservoir par une canalisation de vidange, une vanne d'équilibrage de pression d'air reliée audit réservoir par une canalisation d'équilibrage.For this purpose, the invention relates to a liquid storage device comprising a reservoir, an inlet pipe connected to said reservoir, vacuum means configured to reduce the air pressure in said reservoir in order to draw liquid through the reservoir. inlet pipe, a drain valve connected to said tank by a drain pipe, an air pressure equalization valve connected to said tank by a balancing pipe.

L'invention est remarquable en ce que la canalisation de vidange et la canalisation d'équilibrage sont reliées par une canalisation de jonction pour permettre l'équilibrage de la pression d'air dans la canalisation de vidange.The invention is remarkable in that the drain pipe and the balancing pipe are connected by a connecting pipe to allow the equalization of the air pressure in the drain pipe.

Ainsi, du fait de l'équilibre des pressions d'air entre le réservoir et la canalisation de vidange, il n'existe plus de risque que du liquide soit aspiré dans la canalisation de vidange lors du remplissage du réservoir. Cela permet avantageusement de protéger la vanne de vidange et la canalisation de vidange contre tout endommagement lié au gel. En outre, les opérateurs ne sont pas susceptibles d'être salis par le liquide lors d'une ouverture de la vanne de vidange.Thus, due to the balance of the air pressures between the reservoir and the drain pipe, there is more risk that liquid is sucked into the drain line during filling of the tank. This advantageously makes it possible to protect the drain valve and the drain pipe against any damage due to freezing. In addition, the operators are not likely to be soiled by the liquid during an opening of the drain valve.

De manière préférée, le dispositif de stockage de liquide comporte des moyens de commande adaptés pour, dans une configuration d'utilisation, connecter fluidiquement la canalisation d'équilibrage et la canalisation de jonction et déconnecter fluidiquement la canalisation d'équilibrage et la vanne d'équilibrage.Preferably, the liquid storage device comprises control means adapted to, in a configuration of use, fluidly connect the balancing pipe and the connecting pipe and fluidly disconnect the balancing pipe and the valve. balancing.

Les moyens de commande permettent avantageusement d'équilibrer la pression d'air entre le réservoir et la canalisation de vidange tout en maintenant une dépression étant donné que la vanne d'équilibrage est fermée.The control means advantageously allow to balance the air pressure between the reservoir and the drain line while maintaining a vacuum since the balancing valve is closed.

De manière préférée, le dispositif de stockage de liquide comporte des moyens de commande adaptés pour, dans une configuration de vidange, connecter fluidiquement la canalisation d'équilibrage et la vanne d'équilibrage et déconnecter fluidiquement la canalisation d'équilibrage et la canalisation de jonction.Preferably, the liquid storage device comprises control means adapted to, in a drain configuration, fluidly connect the balancing pipe and the balancing valve and fluidly disconnect the balancing pipe and the connecting pipe. .

Les moyens de commande permettent avantageusement d'éviter toute perte de rendement lors de la vidange étant donné que la canalisation d'équilibrage et la canalisation de jonction sont déconnectées.The control means advantageously make it possible to avoid any loss of efficiency during emptying since the balancing pipe and the junction pipe are disconnected.

Selon un aspect préféré, les moyens de commande se présentent sous la forme d'une vanne trois voies de manière à permettre de passer d'une première configuration à une deuxième configuration de manière rapide et pratique.According to a preferred aspect, the control means are in the form of a three-way valve so as to make it possible to go from a first configuration to a second configuration quickly and conveniently.

De préférence, les moyens de commande sont placés à l'interface entre la canalisation d'équilibrage et la canalisation de jonction. De préférence encore, les moyens de commande sont intégrés à la vanne d'équilibrage afin de limiter l'encombrement et permettre de transformer de manière pratique les dispositifs existants en remplaçant principalement la vanne d'équilibrage.Preferably, the control means are placed at the interface between the balancing pipe and the junction pipe. More preferably, the control means are integrated with the balancing valve in order to limit the space requirement and make it possible to conveniently transform the existing devices by replacing mainly the balancing valve.

De manière préférée, le dispositif de stockage de liquide comporte des moyens d'actionnement configurés, d'une part, pour fermer la vanne de vidange lorsque les moyens de commande sont configurés selon la configuration d'utilisation et, d'autre part, pour ouvrir la vanne de vidange lorsque les moyens de commande sont configurés selon la configuration de vidange. Ainsi, les moyens d'actionnement permettent de synchroniser l'ouverture/fermeture de la vanne de vidange par rapport à la configuration des moyens de commande. Cela est particulièrement avantageux étant donné que les opérateurs n'ont qu'à agir que sur les moyens d'actionnement pour modifier l'ouverture/la fermeture d'une pluralité de canalisations et de vannes. L'utilisation est ainsi grandement simplifiée.Preferably, the liquid storage device comprises actuation means configured, on the one hand, to close the drain valve when the control means are configured according to the use configuration and, on the other hand, to open the drain valve when the control means are configured according to the drain configuration. Thus, the actuating means make it possible to synchronize the opening / closing of the drain valve with respect to the configuration of the control means. This is particularly advantageous since the operators need only act on the actuating means to change the opening / closing of a plurality of pipes and valves. The use is thus greatly simplified.

Selon un aspect préféré, les moyens d'actionnement se présentent sous la forme d'une manette qui peut être aisément manipulée par un opérateur en l'absence d'outils spécifiques.In a preferred aspect, the actuating means is in the form of a joystick that can be easily manipulated by an operator in the absence of specific tools.

L'invention concerne également un véhicule ferroviaire comportant un dispositif tel que présenté précédemment et des toilettes reliées à la canalisation d'entrée dudit dispositif. Le dispositif de stockage peut ainsi stocker de manière temporaire les eaux usées issues desdites toilettes.The invention also relates to a railway vehicle comprising a device as presented above and a toilet connected to the inlet pipe of said device. The storage device can thus temporarily store the wastewater from said toilet.

De préférence, le réservoir est positionné à l'intérieur dudit véhicule tandis que la vanne de vidange est positionnée à l'extérieur dudit véhicule. Ainsi, la vanne de vidange est directement accessible pour un opérateur afin de connecter un récipient de stockage, le réservoir étant protégé contre les intempéries extérieures.Preferably, the tank is positioned inside said vehicle while the drain valve is positioned outside said vehicle. Thus, the drain valve is directly accessible for an operator to connect a storage container, the tank being protected against external weather.

L'invention concerne également un procédé de vidange d'un dispositif de stockage de liquide tel que présenté précédemment. A l'état initial, la vanne de vidange est fermée, la canalisation d'équilibrage et la canalisation de jonction sont connectées fluidiquement et la canalisation d'équilibrage et la vanne d'équilibrage sont déconnectées fluidiquement. Le procédé comporte :

  • une étape d'ouverture de la vanne de vidange,
  • une étape de connexion fluidique de la canalisation d'équilibrage et de la vanne d'équilibrage, et
  • une étape de déconnexion fluidique de la canalisation d'équilibrage et de la canalisation de jonction.
The invention also relates to a method of emptying a liquid storage device as presented above. In the initial state, the drain valve is closed, the balancing pipe and the connecting pipe are fluidly connected and the balancing pipe and the balancing valve are fluidly disconnected. The method comprises:
  • a step of opening the drain valve,

Néanmoins, l'invention s'applique de manière générale dans tout domaine nécessitant un stockage temporaire de liquide, en particulier, le transport routier, maritime ou aérien. L'invention est ici présentée pour le stockage d'eau usée mais il va de soi que d'autres liquides pourraient être stockés.A liquid storage device 10 according to the invention will be presented for application to a railway passenger transport vehicle comprising toilets. Nevertheless, the invention applies generally in any field requiring temporary storage of liquid, in particular, road, sea or air transport. The invention is here presented for the storage of waste water, but it goes without saying that other liquids could be stored.

En référence à la figure 3, il est représenté un véhicule comportant des toilettes 3 reliées à un dispositif 10 de stockage d'eau usée selon une forme de réalisation de l'invention. Les toilettes 3 comportent une cuvette qui peut être vidée par une vanne, en particulier, une chasse d'eau. Le dispositif 10 de stockage d'eau usée comporte un réservoir 2, par exemple, une cuve dont la contenance est de plusieurs centaines de litres. De préférence, le réservoir 2 est positionné dans le véhicule ferroviaire et est protégé des intempéries, en particulier, du gel.With reference to the figure 3 , there is shown a vehicle comprising toilets 3 connected to a device 10 for storing used water according to one embodiment of the invention. The toilet 3 comprises a bowl that can be emptied by a valve, in particular, a flush. The wastewater storage device 10 comprises a tank 2, for example a tank with a capacity of several hundred liters. Preferably, the tank 2 is positioned in the railway vehicle and is protected from the weather, in particular, the gel.

Le dispositif 10 de stockage d'eau usée comporte également une canalisation d'entrée 23 reliant les toilettes 3 audit réservoir 2, en particulier, à sa partie supérieure comme illustré à la figure 3. En outre, le dispositif 10 de stockage d'eau usée comporte des moyens de dépression 5 configurés pour diminuer la pression d'air P2 dans ledit réservoir 2 afin de permettre l'aspiration du liquide via la canalisation d'entrée 23. Les moyens de dépression 5 se présentent de préférence sous la forme d'un dispositif de tirage d'air automatique connu de l'homme du métier. Une dépression de l'ordre de - 0,4 bar (-400 hPa) est par exemple créée dans le réservoir 2. Dans cet exemple, une canalisation de dépression 25 est reliée aux moyens de dépression 5 et débouche dans la partie supérieure du réservoir 2.The waste water storage device 10 also comprises an inlet pipe 23 connecting the toilet 3 to said tank 2, in particular at its upper part. as shown in the figure 3 . In addition, the waste water storage device 10 comprises vacuum means 5 configured to reduce the air pressure P 2 in said tank 2 so as to allow the liquid to be drawn via the inlet pipe 23. The means Depression 5 are preferably in the form of an automatic air draw device known to those skilled in the art. A depression of the order of -0.4 bar (-400 hPa) is for example created in the tank 2. In this example, a vacuum pipe 25 is connected to the vacuum means 5 and opens into the upper part of the tank 2.

Toujours en référence à la figure 3, le dispositif 10 de stockage d'eau usée comporte une vanne de vidange 4 reliée audit réservoir 2 par une canalisation de vidange 24 et une vanne 6 d'équilibrage de pression d'air reliée audit réservoir 2 par une canalisation d'équilibrage 26. La canalisation de vidange 24 est configurée pour plonger dans le réservoir 2 de manière à être immergée lorsque le réservoir 2 est faiblement rempli. Au contraire, la canalisation d'équilibrage 26 débouche dans la partie supérieure du réservoir 2 comme illustré à la figure 3. La vanne de vidange 4 est adaptée pour être reliée à un récipient de stockage d'une installation fixe ou mobile, par exemple, une citerne de rétention. La vanne d'équilibrage 6 est adaptée pour mettre le réservoir 2 à la pression atmosphérique extérieure Pext. Autrement dit, lorsque la vanne d'équilibrage 6 est ouverte, la pression d'air P2 du réservoir 2 est égale à la pression extérieure Pext. Le principe d'utilisation de telles vannes 4, 6 est connu de l'homme du métier. Dans cet exemple, la vanne de vidange 4 comporte un clapet d'ouverture.Still referring to the figure 3 , the waste water storage device 10 comprises a drain valve 4 connected to said tank 2 by a drain pipe 24 and an air pressure equalizing valve 6 connected to said tank 2 by a balancing pipe 26. The drain line 24 is configured to dive into the tank 2 so as to be immersed when the tank 2 is weakly filled. On the contrary, the balancing pipe 26 opens into the upper part of the tank 2 as illustrated in FIG. figure 3 . The drain valve 4 is adapted to be connected to a storage container of a fixed or mobile installation, for example, a holding tank. The balancing valve 6 is adapted to put the tank 2 at the external atmospheric pressure P ext . In other words, when the balancing valve 6 is open, the air pressure P 2 of the tank 2 is equal to the external pressure P ext . The principle of using such valves 4, 6 is known to those skilled in the art. In this example, the drain valve 4 comprises an opening valve.

Selon l'invention, en référence à la figure 3, la canalisation de vidange 24 et la canalisation d'équilibrage 26 sont reliées par une canalisation de jonction 8 pour permettre d'équilibrer la pression d'air P4 dans la canalisation de vidange 24. En mettant en communication le volume d'air de la canalisation de vidange 24 avec le volume d'air du réservoir 2, les pressions P2, P4 s'équilibrent, ce qui empêche toute aspiration.According to the invention, with reference to the figure 3 , the emptying pipe 24 and the balancing pipe 26 are connected by a junction pipe 8 to allow the air pressure P 4 to be balanced in the drain pipe 24. By putting the volume of air of the the drain line 24 with the air volume of the tank 2, the pressures P 2 , P 4 are balanced, which prevents any aspiration.

Dans cet exemple, le dispositif 10 de stockage d'eau usée comporte également des moyens de commande 7 configurés pour, dans une configuration d'utilisation, connecter fluidiquement la canalisation d'équilibrage 26 et la canalisation de jonction 8 et déconnecter fluidiquement la canalisation d'équilibrage 26 et la vanne d'équilibrage 6 comme illustré aux figures 5 et 6. La configuration d'utilisation permet d'égaliser la pression d'air P2 du réservoir 2 avec la pression d'air P4 de la canalisation de vidange 24. Comme les pressions P2, P4 sont équilibrées, il n'existe plus de risque que de l'eau usée soit aspirée par la canalisation de vidange 24 en l'absence de vidange.In this example, the wastewater storage device 10 also comprises control means 7 configured for, in a configuration of use, fluidly connecting the balancing pipe 26 and the connecting pipe 8 and fluidly disconnecting the pipe of the pipe. balancing 26 and the valve 6 as shown in FIGS. Figures 5 and 6 . The use configuration makes it possible to equalize the air pressure P 2 of the tank 2 with the air pressure P 4 of the drain line 24. Since the pressures P 2 , P 4 are balanced, it no longer exists. risk of waste water being sucked through the drain pipe 24 in the absence of emptying.

Les moyens de commande 7 sont également configurés pour, dans une configuration de vidange, connecter fluidiquement la canalisation d'équilibrage 26 et la vanne d'équilibrage 6 et déconnecter fluidiquement la canalisation d'équilibrage 26 et la canalisation de jonction 8 comme illustré aux figures 7 et 6. La configuration de vidange permet d'égaliser la pression d'air P2 du réservoir 2 avec la pression d'air Pext de l'extérieur. Ainsi, l'eau usée peut être vidangée du réservoir 2 de manière pratique et rapide. En outre, comme la canalisation d'équilibrage 26 est déconnectée fluidiquement, le rendement lors de la vidange est élevé.The control means 7 are also configured for, in a drain configuration, fluidly connect the balancing pipe 26 and the balancing valve 6 and fluidly disconnect the balancing pipe 26 and the junction pipe 8 as illustrated in FIGS. Figures 7 and 6 . The emptying configuration makes it possible to equalize the air pressure P 2 of the tank 2 with the air pressure P ext from the outside. Thus, the waste water can be drained from the tank 2 conveniently and quickly. In addition, since the balancing pipe 26 is fluidly disconnected, the efficiency during the emptying is high.

De préférence, les moyens de commande 7 sont positionnés à l'interface entre la canalisation d'équilibrage 26 et la canalisation de jonction 8. De manière préférée, les moyens de commande 7 sont intégrés à la vanne d'équilibrage 6 afin de disposer d'un dispositif compact. Comme illustré aux figures 6 et 8, les moyens de commande 7 se présentent de manière préférée sous la forme d'une vanne trois voies mais il va de soi que d'autres types de moyens de commande 7 pourraient convenir, par exemple, un ensemble de vannes simples mais celles-ci présentent un encombrement augmenté et sont plus contraignantes à utiliser.Preferably, the control means 7 are positioned at the interface between the balancing pipe 26 and the junction pipe 8. Preferably, the control means 7 are integrated with the balancing valve 6 in order to provide a compact device. As illustrated in Figures 6 and 8 , the control means 7 are preferably in the form of a three-way valve but it goes without saying that other types of control means 7 could be suitable, for example, a set of simple valves but these have an increased size and are more restrictive to use.

De manière préférée, en référence aux figures 5 et 7, le dispositif 10 de stockage d'eau usée comporte des moyens d'actionnement 9 configurés, d'une part, pour fermer la vanne de vidange 4 lorsque les moyens de commande 7 sont configurés selon la configuration d'utilisation et, d'autre part, pour ouvrir la vanne de vidange 4 lorsque les moyens de commande 7 sont configurés selon la configuration de vidange. Dans cet exemple, les moyens d'actionnement 9 se présentent sous la forme d'une manette adaptée pour agir de manière simultanée sur les moyens de commande 7 (vanne trois voies) et sur l'ouverture de la vanne de vidange 4 (clapet d'ouverture). De tels moyens d'actionnement 9 permettent de centraliser l'ensemble des opérations de connexion/déconnexion/fermeture/ouverture, ce qui facilite le travail quotidien des opérateurs.Preferably, with reference to Figures 5 and 7 , the waste water storage device 10 comprises actuating means 9 configured, on the one hand, to close the drain valve 4 when the control means 7 are configured according to the configuration of use and, on the other hand, on the other hand, to open the drain valve 4 when the control means 7 are configured according to the emptying configuration. In this example, the actuating means 9 are in the form of a handle adapted to act simultaneously on the control means 7 (three-way valve) and on the opening of the drain valve 4 (valve d 'opening). Such actuating means 9 make it possible to centralize all the connection / disconnect / close / open operations, which facilitates the daily work of the operators.

De manière avantageuse, il est possible de transformer un dispositif de stockage selon l'art antérieur en un dispositif de stockage selon l'invention de manière pratique et peu coûteuse. En effet, il suffit de remplacer le module de vannes par un nouveau module de vannes comportant une canalisation de jonction 8 et une vanne trois voies.Advantageously, it is possible to transform a storage device according to the prior art into a storage device according to the invention in a practical and inexpensive way. Indeed, it suffices to replace the valve module with a new valve module comprising a junction pipe 8 and a three-way valve.

Un exemple de mise en oeuvre de l'invention va être dorénavant présenté.An exemplary implementation of the invention will now be presented.

Lorsque le véhicule ferroviaire est en service, la manette 9 est en configuration d'utilisation comme présenté précédemment. La vanne de vidange 4 est fermée, la canalisation d'équilibrage 26 et la canalisation de jonction 8 sont connectées fluidiquement tandis que la canalisation d'équilibrage 26 et la vanne d'équilibrage 6 sont déconnectées fluidiquement. Ainsi, comme la pression d'air P2 du réservoir 2 est égale à celle de la pression d'air P4 de la canalisation de vidange 24, il n'existe pas de risque que de l'eau usée soit aspirée dans la canalisation de vidange 24 lorsque le réservoir 2 se remplit. Autrement dit, les inconvénients de l'art antérieur sont supprimés.When the rail vehicle is in use, the lever 9 is in the configuration of use as presented above. The drain valve 4 is closed, the balancing pipe 26 and the connecting pipe 8 are fluidly connected while the balancing pipe 26 and the balancing valve 6 are fluidly disconnected. Thus, since the air pressure P 2 of the tank 2 is equal to that of the air pressure P 4 of the drain pipe 24, there is no risk that wastewater is sucked into the pipe emptying 24 when the tank 2 fills. In other words, the disadvantages of the prior art are removed.

Pour vidanger l'eau usée du réservoir, il suffit à l'opérateur d'actionner la manette 9 afin d'ouvrir la vanne de vidange 4, de connecter fluidiquement la canalisation d'équilibrage 26 et la vanne d'équilibrage 6 et de déconnecter fluidiquement la canalisation d'équilibrage 26 et la canalisation de jonction 8. Autrement dit, la manette 9 est en configuration de vidange comme présenté précédemment.To drain the wastewater from the tank, it is sufficient for the operator to operate the handle 9 to open the drain valve 4, to fluidly connect the balancing pipe 26 and the balancing valve 6 and to disconnect fluidically the balancing pipe 26 and the junction pipe 8. In other words, the lever 9 is in the empty configuration as presented above.

Lors de la rotation de la manette 9, la vanne trois voies 7 est actionnée simultanément au clapet d'ouverture de la vanne de vidange 4. Ainsi, la pression d'air P2 du réservoir 2 s'équilibre à la pression extérieure Pext pour permettre à l'eau usée d'être aspirée dans un récipient de stockage via la vanne de vidange 4. Comme la canalisation d'équilibrage 26 et la canalisation de jonction 8 sont déconnectées, il n'y a pas de perte de rendement lors de la vidange.During the rotation of the handle 9, the three-way valve 7 is actuated simultaneously with the opening valve of the drain valve 4. Thus, the air pressure P 2 of the tank 2 equilibrates with the external pressure P ext to allow the waste water to be drawn into a storage container via the drain valve 4. As the balancing pipe 26 and the connecting pipe 8 are disconnected, there is no loss of efficiency when of the drain.

L'étape d'ouverture, l'étape de connexion fluidique et l'étape de déconnexion fluidique sont réalisées simultanément de manière à limiter le nombre de manipulations par l'opérateur, tout en permettant une vidange rapide. Une fois la vidange terminée, la manette 9 est refermée et une dépression est de nouveau créée dans le réservoir 2.The opening step, the fluidic connection step and the fluidic disconnection step are performed simultaneously so as to limit the number of operations by the operator, while allowing rapid emptying. Once the emptying is complete, the handle 9 is closed and a vacuum is created again in the tank 2.

Grâce à l'invention, toute présence d'eau usée dans la canalisation de vidange 24 est évitée. Aussi, le dispositif de stockage 10 n'est pas susceptible de s'endommager en cas de gel ou de salir un opérateur.Thanks to the invention, any presence of waste water in the drain line 24 is avoided. Also, the storage device 10 is not likely to be damaged in case of frost or dirty operator.
