10 Des dispositifs de ce type sont connus de longue date.Devices of this type have been known for a long time.
Ils trouvent leur application et ont été proposés essentiellement dans le domaine de la désinfection des lavabos en domaine hospitalier ou dans les établissements publics.They find their application and have been proposed mainly in the field of disinfecting sinks in hospitals or in public establishments.
Ainsi la demande de brevet en FRANCE 80-23772 au nomThus the patent application in FRANCE 80-23772 in the name
15 du demandeur décrit un dispositif du type rappelé ci-dessus. Dans ce dispositif, un piston est actionné par pression différentiel¬ le, en l'occurrence un venturi, et une chambre de mélange permet de mélanger un bactéricide avec le fluide vecteur, à savoir l'eau s'écoulant dans l'installation sanitaire équipée du dispositif.15 of the applicant describes a device of the type recalled above. In this device, a piston is actuated by differential pressure, in this case a venturi, and a mixing chamber makes it possible to mix a bactericide with the carrier fluid, namely the water flowing in the sanitary installation equipped of the device.
20 Bien -qu'il donne entière satisfaction, ce dispositif présente un certain nombre d'inconvénients.Although it is entirely satisfactory, this device has a certain number of drawbacks.
Il est en effet souhaitable, contrairement à ce qui se passe dans ce dispositif, que le mélange entre les deux fluides, s'il doit intervenir, s'opère sur le lieu même où il doit agir,It is indeed desirable, contrary to what happens in this device, that the mixture between the two fluids, if it has to intervene, takes place on the very place where it must act,
25 de manière à être efficient. Le mélange dans le dispositif et donc le stockage du produit mélangé diminue en effet l'efficacité du produit bactéricide.25 so as to be efficient. The mixing in the device and therefore the storage of the mixed product in fact reduces the effectiveness of the bactericidal product.
La présente invention a pour objet de remédier à cet inconvénient. 30 Elle a également, par extension, pour objet de proposer un dispositif qui permette de distribuer une quantité dosée d'un fluide quelconque, avec éjection simultanée et également dosée d'une quantité de fluide vecteur. Conformément à l'invention ce résultat est obtenu avec un dispositif du type décrit en préambule, caractérisé en ce que ledit piston est un piston .à trois étages dont chacun délimite une chambre correspondante, à savoir respectivement et successivement, une chambre de dosage, une chambre de mise à l'air atmosphérique et une seconde chambre de dosage, la première chambre de dosage étant reliée par un clapet anti-retour au réseau de circulation du fluide vecteur en amont du venturi et comportant un orifice d'expulsion, la seconde chambre de dosage étant reliée à un orifice d'aspiration du fluide â doser et à distribuer et à un orifice d'expulsion de celui-ci, l'orifice d'aspiration étant obturé ou dégagé par un piston soumis à l'effet venturi au travers d'un orifice situé en aval dudit venturi, orifice auquel est également reliée la chambre de commande du piston.The object of the present invention is to remedy this drawback. It also has, by extension, the object of providing a device which makes it possible to dispense a metered quantity of any fluid, with simultaneous ejection and also metered a quantity of carrier fluid. In accordance with the invention, this result is obtained with a device of the type described in the preamble, characterized in that said piston is a three-stage piston, each of which delimits a corresponding chamber, namely respectively and successively, a metering chamber, a atmospheric air chamber and a second metering chamber, the first metering chamber being connected by a non-return valve to the vector fluid circulation network upstream of the venturi and comprising an expulsion orifice, the second chamber metering device being connected to a suction port of the fluid to be metered and dispensed and to an expulsion port thereof, the suction port being closed or released by a piston subjected to the venturi effect through an orifice located downstream of said venturi, orifice to which the piston control chamber is also connected.
Dans tout ce qui suit, on se limitera à un exemple dans lequel l'installation est une installation sanitaire, en l'occurrence un lavabo, le fluide vecteur étant de l'eau et. le fluide à doser un bactéricide. H est clair cependant que l'invention ne doit pas être comprise comme se limitant à cette application.In what follows, we will limit ourselves to an example in which the installation is a sanitary installation, in this case a sink, the carrier fluid being water and. the fluid to dose a bactericide. It is clear, however, that the invention should not be understood as being limited to this application.
Ainsi le fluide vecteur peut être par exemple un gaz, tel que azote, air comprimé ou gaz carbonique. La pression différentielle peut également être remplacée par tout système fonctionnellement équivalent.Thus the carrier fluid can be for example a gas, such as nitrogen, compressed air or carbon dioxide. The differential pressure can also be replaced by any functionally equivalent system.
De même, le fluide à doser peut être de toute nature,' par exemple liquide, gazeux, pâteux ou solide, â l'état de poudre ou granuleux, c'est-à-dire susceptible de s'écouler. Ainsi, par exemple, le fluide à doser pourrait être du grain pour l'alimentation animale, un produit à doser pour l'industrie alimentaire et la conserverie, etc..Similarly, the fluid to be assayed can be of any kind, 'for example liquid, gaseous, pasty or solid in the state of powder or granular, that is to say capable of flowing. Thus, for example, the dosing fluid could be grain for animal feed, a dosing product for the food industry and the canning industry, etc.
On comprendra mieux l'invention à l'aide de la description ci-après d'un mode avantageux de mise en oeuvre, donné à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels : - la figure 1 est une vue schématique illustrant l'utilisation du dispositif de l'invention monté sur la conduite d'écoulement d'un lavabo.The invention will be better understood with the aid of the description below of an advantageous embodiment, given by way of nonlimiting example with reference to the appended drawings in which: - Figure 1 is a schematic view illustrating the use of the device of the invention mounted on the flow pipe of a sink.
- la figure 2 est une vue en coupe longitudinale du dispositif conforme à l'invention.- Figure 2 is a longitudinal sectional view of the device according to the invention.
Le dispositif (1) conforme à l'invention est disposé entre la conduite d'évacuation (2) d'un lavabo (3) et un réservoir de stockage (4) d'un produit à doser et à amener, au travers dudit dispositif (1), dans la conduite d'évacuation (2). II s'agira- par exemple d'un produit bactéricide.The device (1) according to the invention is disposed between the evacuation pipe (2) of a sink (3) and a storage tank (4) of a product to be dosed and brought, through said device (1), in the discharge line (2). It will, for example, be a bactericidal product.
Le dispositif (1) comporte une chambre de dosage d'eauThe device (1) comprises a water metering chamber
(5) et une chambre de dosage de bactéricide (6). Ces deux chambres sont séparées par une chambre de sécurité (7) évitant le(5) and a bactericide metering chamber (6). These two chambers are separated by a security chamber (7) avoiding the
' mélange entre les deux liquides à l'intérieur du dispositif. Ceci sera explicité plus en détails ultérieurement. Mixing between the two liquids within the device. This will be explained in more detail later.
La chambre (6) et la chambre (5) sont chacune reliées par une conduite (8,9) au conduit d'évacuation (2) du lavabo. De préférence, la conduite (9) débouchera au dessus de laThe chamber (6) and the chamber (5) are each connected by a pipe (8,9) to the evacuation pipe (2) of the sink. Preferably, the pipe (9) will open above the
•conduite (8), de manière telle que l'eau entraine le bactéricide '" par ruissellement. • pipe (8), in such a way that the water carries the bactericide '"by runoff.
Le dispositif (1) fonctionne de manière automatique sous l'effet de l'arrivée d'eau du lavabo, dont on a représenté le tuyau d'arrivée (10), sur lequel est ménagée une dérivationThe device (1) operates automatically under the effect of the water supply from the sink, of which the inlet pipe (10) is shown, on which a bypass is provided
(11) qui traverse le dispositif. Sur cette dérivation est montée un venturi qui commande le dispositif (1).(11) which passes through the device. On this branch is mounted a venturi which controls the device (1).
On décrira maintenant plus en détails le dispositif (1) en référence à la figure 2.The device (1) will now be described in more detail with reference to FIG. 2.
Le dispositif (1) se présente extérieurement sous la forme d'un carter (12) de forme générale cylindrique. II comporte respectivement une chambre de commandeThe device (1) is externally in the form of a casing (12) of generally cylindrical shape. II respectively has a control chamber
(13), ainsi que les chambres de dosage d'eau (5) et de liquide à doser et à distribuer (6) précédemment citées. Les deux chambres (5) et (6) sont séparées par une zone de sécurité constituée par la chambre de sécurité (7) précitée. Les chambres (5,7,13) sont de forme générale cylindri¬ que. La chambre (6) est en T, chaque barre étant constituée par une portion cylindrique, le pied étant d'axe commun avec Taxe longitudinal des chambres (5,7,13) ou parallèle à celui-ci. Sur ledit axe se déplace un piston unique (14) à trois étages.(13), as well as the metering chambers of water (5) and of liquid to be metered and dispensed (6) previously mentioned. The two chambers (5) and (6) are separated by a security zone constituted by the aforementioned security chamber (7). The chambers (5,7,13) are generally cylindrical in shape. The chamber (6) is T-shaped, each bar being constituted by a cylindrical portion, the base being of common axis with the longitudinal axis of the chambers (5,7,13) or parallel to it. On said axis moves a single piston (14) with three stages.
Le carter (12) renferme un venturi (15) que l'on va décrire plus en détails. Sur la conduite d'arrivée d'eau (10) est ménagée une dérivation (11) qui amène l'eau d'alimentation du lavabo à traverser le dispositif (1) au niveau du venturi (15). Ce venturi est de type classique et comporte deux orifices de venturi respectivement amont (16) et aval (17). L'eau d'alimenta- tion qui entre dans le venturi par l'orifice (18) en sort par l'orifice (19) vers les robinets -du lavabo.The casing (12) contains a venturi (15) which will be described in more detail. On the water inlet pipe (10) is provided a bypass (11) which brings the sink supply water through the device (1) at the venturi (15). This venturi is of conventional type and comprises two venturi orifices upstream (16) and downstream (17) respectively. The feed water which enters the venturi through the orifice (18) leaves it through the orifice (19) towards the taps -of the sink.
Le jeu pression-dépression au niveau des orifices (16,17) conditionne le fonctionnement de l'ensemble du dispositif A cet effet, le dispositif comporte intérieurement ledit piston (14) mobile en translation.The pressure-vacuum clearance at the level of the orifices (16, 17) conditions the operation of the entire device. To this end, the device internally comprises said piston (14) movable in translation.
Le piston (14) comporte trois étages dont chacun se déplace dans une des chambres décrites précédemment.The piston (14) has three stages, each of which moves in one of the chambers described above.
Le premier étage (20) est disposé entre la chambre de commande (13) et la chambre de dosage d'eau (5). Sa face arrière (21) est soumise à la pression déterminée par l'orifice de venturi aval (17) .The first stage (20) is arranged between the control chamber (13) and the water metering chamber (5). Its rear face (21) is subjected to the pressure determined by the downstream venturi orifice (17).
La face avant (22) est soumise par contre à la pression déterminée par l'orifice de venturi amont (16). Celui-ci est en effet relié par une conduite d'amenée (23) à la chambre de dosage (5), au travers d'un orifice (43) muni d'un clapet anti-retou (38). De la même manière, la chambre de dosage d'eau (5) est reliée à un orifice d'expulsion (24) par un orifice (42) muni d'un clapet anti-retour (25) muni d'un ressort taré (26) . Le second étage (27) du piston délimite avec le carter la chambre de mise à l'air atmosphérique (7), reliée donc à l'atmosphère par une conduite de mise à l'air (28).The front face (22) is however subjected to the pressure determined by the upstream venturi orifice (16). The latter is in fact connected by a supply pipe (23) to the metering chamber (5), through an orifice (43) provided with a non-return valve (38). In the same way, the water metering chamber (5) is connected to an expulsion orifice (24) by an orifice (42) provided with a non-return valve (25) provided with a calibrated spring ( 26). The second stage (27) of the piston defines with the housing the atmospheric venting chamber (7), therefore connected to the atmosphere by a venting pipe (28).
Le troisième étage (29) du piston se déplace dans la chambre (6) en T précitée. Cette chambre comporte en outre, sur sa portion perpendiculaire à l'axe du dispositif, deux clapets anti-retour (30-31) aptes à masquer ou libérer respecti¬ vement l'orifice d'aspiration (32) du liquide à doser et l'orifice d'expulsion (33) dudit liquide. - 5 -The third stage (29) of the piston moves in the aforementioned T-chamber (6). This chamber also comprises, on its portion perpendicular to the axis of the device, two non-return valves (30-31) capable of masking or releasing respecti¬ vely the suction orifice (32) of the liquid to be dosed and l 'expulsion orifice (33) of said liquid. - 5 -
Le clapet (31) est de type simple se déplaçant dans un alésage du dispositif et étant rappelé par un ressort (34) taré.The valve (31) is of simple type moving in a bore of the device and being returned by a calibrated spring (34).
Le clapet (30) est soumis pour sa part à la pression régnant dans la chambre de commande (13) précitée. Celle-ci est en effet munie d'un orifice (35) qui débouche sur une conduite d'amenée (36) traversant le dispositif pour déboucher sur la face arrière (37) du piston du clapet (30). Le piston dudit clapet (30) détermine en outre entre la conduite (36) et la chambre (6) une chambre secondaire de mise à l'air atmosphérique (39) débouchant sur l'extérieur par une conduite de mise à l'air (40). Le clapet (30) est sollicité par un ressort (41) qui tend à le ramener en position d'ouverture de l'orifice (32).The valve (30) is subjected for its part to the pressure prevailing in the aforementioned control chamber (13). The latter is in fact provided with an orifice (35) which opens onto a supply line (36) passing through the device to open onto the rear face (37) of the piston of the valve (30). The piston of said valve (30) further determines between the line (36) and the chamber (6) a secondary atmospheric air chamber (39) opening onto the outside via an air line ( 40). The valve (30) is biased by a spring (41) which tends to return it to the opening position of the orifice (32).
Le fonctionnement du dispositif est le suivant, illustré par des flèches aidant à la compréhension. S'il n'y a aucune circulation d'eau dans la conduiteThe operation of the device is as follows, illustrated by arrows to aid understanding. If there is no water circulation in the pipe
(10), et donc dans le venturi (15) f l'effet de ce dernier est nul. La force totale exercée sur la paroi (21) du premier(10), and therefore in the venturi (15) f the effect of the latter is zero. The total force exerted on the wall (21) of the first
" étage du piston étant supérieure à celle exercée sur la paroi"piston stage being greater than that exerted on the wall
(22) du même étage, le piston est disposé vers la droite par rapport au dessin.(22) of the same stage, the piston is arranged to the right with respect to the drawing.
Dés qu'une circulation d'eau s'établit dans la conduite (10) l'eau traverse le venturi (15). L'effet venturi entraine une surpression sur l'orifice (16) et une dépression sur l'orifice (17). La surpression sur l'orifice (16) ouvre le clapet anti-retour (38) et amène cette surpression sur la face (22) du piston. Parallèlement, l'effet venturi crée une dépression sur l'orifice (17) et donc une aspiration par cet orifice de l'eau contenue dans la chambre (13). La face (21) du piston vient donc se plaquer contre le fond (44) de la chambre (13), tandis que la chambre (5)se remplit totalement d'eau.As soon as a circulation of water is established in the pipe (10) the water passes through the venturi (15). The venturi effect causes an overpressure on the orifice (16) and a depression on the orifice (17). The overpressure on the orifice (16) opens the non-return valve (38) and brings this overpressure on the face (22) of the piston. At the same time, the venturi effect creates a depression on the orifice (17) and therefore a suction through this orifice of the water contained in the chamber (13). The face (21) of the piston therefore presses against the bottom (44) of the chamber (13), while the chamber (5) is completely filled with water.
Le ressort (26) du clapet (25) est calculé de manière telle que, malgré la pression régnant dans la chambre (5) à cet instant, il ne puisse s'ouvrir.The spring (26) of the valve (25) is calculated in such a way that, despite the pressure prevailing in the chamber (5) at this instant, it cannot open.
Dans le même temps, la dépression dans la chambre (13) est transmise par l'orifice (35) et la conduite (36) sur la face arrière (37) du piston du clapet (30). Avec l'aide du ressort (41) le piston se déplace vers le haut par rapport au dessin.At the same time, the vacuum in the chamber (13) is transmitted through the orifice (35) and the line (36) on the rear face (37) of the valve piston (30). With help of the spring (41) the piston moves upward relative to the drawing.
Simultanément, le ressort (4 l) recule. L'orifice (32) étant dégagé, la chambre de dosage (6) se remplit du produit à doser. Le clapet (31) empêche l'aspiration par l'orifice (7).At the same time, the spring (4 l) moves back. The opening (32) being cleared, the metering chamber (6) is filled with the product to be metered. The valve (31) prevents suction through the orifice (7).
Si Teau s'arrête de circuler, l'effet venturi est stoppé. Le piston (14) quitte la paroi (44) et se déplace vers la droite par rapport au dessin.If the water stops circulating, the venturi effect is stopped. The piston (14) leaves the wall (44) and moves to the right with respect to the drawing.
L'eau contenue dans la chambre (5) est expulsée par l'orifice (24), via le clapet (42,25), le clapet anti-retour (38) empêchant le passage de l'eau par cette issue.The water contained in the chamber (5) is expelled through the orifice (24), via the valve (42,25), the non-return valve (38) preventing the passage of water through this outlet.
La pression étant également rétablie dans la conduitePressure is also restored in the line
(36), le piston du clapet (30) revient obturer l'orifice (32) et le liquide à doser contenu dans la chambre (6) est, sous l'effet du déplacement du piston (14), expulsé par l'orifice (33).Le ressort du clapet (31) est taré en conséquence.(36), the piston of the valve (30) returns to close the orifice (32) and the metering liquid contained in the chamber (6) is, under the effect of the displacement of the piston (14), expelled by the orifice The valve spring (31) is calibrated accordingly.
Dès qu'il y a circulation à nouveau de l'eau, le cycle recommence. Ainsi, dès que l'utilisateur a terminé l'usage de l'appareil sanitaire et qu'il coupe l'alimentation en eau, le dispositif entre en fonctionnement.As soon as there is water circulation again, the cycle starts again. Thus, as soon as the user has finished using the sanitary appliance and cuts off the water supply, the device enters into operation.
Les orifices de mise à l'air (28,40) empêchent tout mélange de Teau et du bactéricide dans l'appareil.The air vents (28,40) prevent water and bacteria from mixing in the device.
Si malgré tout un mélange est désiré, il peut être opéré hors de l'appareil en reliant les deux conduites (24) et (33). Ceci ne pose aucun problème puisque l'éjection des deux liquides est simultanée et proportionnelle.If, despite everything, a mixture is desired, it can be operated outside the device by connecting the two pipes (24) and (33). This poses no problem since the ejection of the two liquids is simultaneous and proportional.
Le même dispositif peut être utilisé pour le soutirage de plusieurs liquides en multipliant d'autant les chambres (6) et leurs organes fonctionnels. The same device can be used for drawing off several liquids by multiplying the chambers (6) and their functional organs accordingly.
