- Parallel seating valves allow less disturbed fluid flow. But their design does not allow regulation.
- Full-flow valves are generally ball valves or cylindrical valves. These faucets reconstitute the fluid vein integrally but have two disadvantages.
- the first of these drawbacks is the difficulty of being able to perfectly seal the valve between upstream and downstream because the sealing surfaces rub against each other during maneuvers and are scratched, which makes the realization of these faucets in high pressure and high temperature impossible.
- the second disadvantage is the high torque required for the operation of the valve because of the significant friction of the sealing surfaces, making it difficult to produce these valves in large diameter and very difficult the control function.
- they generally have a retention zone.
- Butterfly valves can be used as regulators but are not very tight.
- the pressure drop is generated by the simple reduction of the fluid passage section and not by devices for varying the path of the fluid. Output speeds are therefore very important. They cause a disturbance of the fluid vein and are subject to oscillations.
- valves and valves currently used combine a regulating function and a closing and sealing function.
- regulatory ranges are often limited.

Le dispositif s'applique à toutes les fonctions pouvant être remplies par tous les types de vannes ou de robinets existants.The device applies to all functions that can be fulfilled by all types of existing valves or faucets.
Le dispositif a pour but de remplacer les vannes ou robinets existants actuellement, en diminuant les puissances nécessaires à leur manœuvre et en 2Q améliorant l'écoulement du fluide._The device is intended to replace the existing valves or valves currently, decreasing the powers necessary for their operation and Q 2 flow improvers fluide._
Etat de la technique antérieure et problème poséState of the prior art and problem
Les vannes, ou les robinets existants remplissent soit une fonction de 25 régulation de débit soit une fonction de fermeture et d'étanchéité. Aucun dispositif ne permet de remplir les deux fonctions. Quatre grands principes technologiques existent :The valves or existing fill valves is a function of flow control 25 is a function of closing and sealing. No device can fulfill both functions. Four major technological principles exist:
Les vannes à siège constituées par l'avancée d'un opercule contre un siège, les vannes à sièges parallèles constituées par deux opercules glissant «Q perpendiculairement à la veine fluide pour s'appuyer sur les sièges en fin de course, les robinets à tournant sphérique ou cylindrique où la fermeture est constituée par la rotation du noyau percé, et les vannes à papillon. Les vannes à siège présentent l'avantage de pouvoir étanchéifier des pressions très hautes et des températures élevées. Par contre dans ce type de « - vanne, le fluide doit passer au travers du siège. La tige qui tient l'opercule vient s'appuyer sur le siège, l'écoulement du fluide suit soit un parcours en forme de Z, soit un angle à 90°. Ceci induit une perturbation de l'écoulement et une perte de charge.
Les vannes à sièges parallèles permettent une circulation du fluide moins perturbée. Mais leur conception ne permet pas de faire de la régulation. L'écoulement est très perturbé pendant la fermeture, leur mécanisme est compliqué et elle enferme une quantité de fluide entre les deux opercules qui en cas de dépressurisation peut au mieux empêcher la vanne de s'ouvrir. De plus le frottement des opercules sur les sièges pendant les manœuvres raye les sièges et détériore la vanne.The seat valves consist of the advance of a cover against a seat, the parallel-seat valves constituted by two covers sliding " Q perpendicular to the fluid vein to rest on the seats at the end of the race, the taps to turn spherical or cylindrical where the closure is constituted by the rotation of the pierced core, and the butterfly valves. The seat valves have the advantage of being able to seal very high pressures and high temperatures. On the other hand, in this type of valve, the fluid must pass through the seat. The rod holding the lid comes to rest on the seat, the fluid flow follows either a Z-shaped path or a 90 ° angle. This induces a disturbance of the flow and a loss of charge. Parallel seating valves allow less disturbed fluid flow. But their design does not allow regulation. The flow is very disturbed during closure, their mechanism is complicated and it encloses a quantity of fluid between the two covers which in case of depressurization can at best prevent the valve from opening. In addition, the friction of the covers on the seats during the maneuvers scratches the seats and damages the valve.
Les robinets à passage intégral sont généralement des robinets à tournant sphérique ou cylindrique. Ces robinets reconstituent la veine fluide de façon intégrale mais présentent deux inconvénients. Le premier de ces inconvénients est la difficulté de pouvoir étanchéifîer parfaitement le robinet entre l'amont et l'aval car les surfaces d'étanchéité frottent les unes sur les autres lors des manœuvres et s'en trouvent rayées, ce qui rend la réalisation de ces robinets en haute pression et haute température impossible. Le deuxième inconvénient est le couple élevé nécessaire à la manœuvre du robinet du fait des frottements importants des surfaces d'étanchéité, rendant problématique la réalisation de ces vannes en gros diamètre et très difficile la fonction de régulation. De plus, elles possèdent généralement une zone de rétention. Les vannes à papillons peuvent être utilisées en organe de régulation mais ne sont pas très étanches. De plus, la perte de charge est générée par la simple réduction de la section de passage du fluide et non par des dispositifs de variation de la trajectoire du fluide. Les vitesses de sortie sont donc très importantes. Elles provoquent une perturbation de la veine fluide et sont sujettes à des oscillations.Full-flow valves are generally ball valves or cylindrical valves. These faucets reconstitute the fluid vein integrally but have two disadvantages. The first of these drawbacks is the difficulty of being able to perfectly seal the valve between upstream and downstream because the sealing surfaces rub against each other during maneuvers and are scratched, which makes the realization of these faucets in high pressure and high temperature impossible. The second disadvantage is the high torque required for the operation of the valve because of the significant friction of the sealing surfaces, making it difficult to produce these valves in large diameter and very difficult the control function. In addition, they generally have a retention zone. Butterfly valves can be used as regulators but are not very tight. In addition, the pressure drop is generated by the simple reduction of the fluid passage section and not by devices for varying the path of the fluid. Output speeds are therefore very important. They cause a disturbance of the fluid vein and are subject to oscillations.
Le problème posé par les vannes et les robinets actuellement utilisés est qu'aucune des réalisations existantes ne combinent une fonction de régulation et une fonction de fermeture et d'étanchéité. De plus, les plages de régulations sont souvent limitées.
The problem posed by the valves and valves currently used is that none of the existing embodiments combine a regulating function and a closing and sealing function. In addition, regulatory ranges are often limited.
Résumé de l'inventionSummary of the invention
Le dispositif objet de l'invention consiste à réaliser une vanne de régulation engendrant une perte de charge très faible à pleine ouverture et très importante en fin de course, voire une étanchéité autoclave sur siège permettant une bonne étanchéité en haute pression et en haute température tout en gardant un couple de manœuvre très faible.The device according to the invention consists in producing a control valve generating a very low pressure drop at full opening and very important at the end of the stroke, or even an autoclave seal on seat for good sealing at high pressure and at high temperature. keeping a very low maneuvering torque.
Pour ce faire, on place sur une conduite un support (2a), (2b), (2c), (2d), (2e) ou (2f) sur lequel on fixe une cartouche (3a), (3b), (3c), (3d), (3e) ou (3f) contenant la quasi-totalité des organes nécessaires au fonctionnement du dispositif. Le fluide passe à travers des ouvertures (6a) ou (6b) à travers une partie de la cartouche (3a), (3b), (3c), (3d), (3e) ou (3f). Un tube mobile (5) obture plus ou moins ces ouvertures (6a) ou (6b) suivant la perte de charge désirée. Des dispositifs de perte de charge additionnels peuvent compléter les ouvertures (6a) ou (6b) et adapter le dispositif aux différents écoulements. Un siège d'étanchéité est éventuellement placé en fin de course.To do this, a support (2a), (2b), (2c), (2d), (2e) or (2f) on which a cartridge (3a), (3b), (3c) is placed on a pipe is placed on a pipe. ), (3d), (3e) or (3f) containing almost all the organs necessary for the operation of the device. The fluid passes through openings (6a) or (6b) through a portion of the cartridge (3a), (3b), (3c), (3d), (3e) or (3f). A movable tube (5) closes more or less these openings (6a) or (6b) according to the desired pressure drop. Additional pressure drop devices can complete the openings (6a) or (6b) and adapt the device to the different flows. A sealing seat is possibly placed at the end of the race.
L'utilisation d'un tube mobile (5) comme opercule diminue les masses à déplacer et les forces de pression et donc l'énergie à mettre en œuvre pour manœuvrer le dispositif.The use of a movable tube (5) as a cap decreases the masses to move and the pressure forces and therefore the energy to implement to maneuver the device.
AvantagesAdvantages
Le dispositif permet de réaliser des vannes de régulation et de fermeture quelque soit la pression et la température et ceci avec une très faible perte de charge en position complètement ouverte. L'organe mobile de régulation (5) et de fermeture peut être léger, ce qui est particulièrement avantageux pour les gros diamètres. Il permet de choisir la force d'appui autoclave par le réglage de la position du contact entre le siège (4) et le tube mobile (5). Le faible poids des organes en mouvement ainsi que le réglage de la force autoclave engendrent un couple de manœuvre très faible, donc de petites motorisations.The device makes it possible to realize control and closing valves whatever the pressure and the temperature and this with a very small loss of load in completely open position. The mobile regulating member (5) and closing can be light, which is particularly advantageous for large diameters. It allows to choose the autoclave support force by adjusting the position of the contact between the seat (4) and the movable tube (5). The low weight of the moving parts as well as the adjustment of the autoclave force generate a very low maneuvering torque, therefore small engines.
Grâce à cela, la réalisation de vannes actionnées par générateur autonome est possible. En effet, la faible puissance nécessaire à la manœuvre peut-être générée à partir du fluide ou à partir de l'environnement extérieur, stockée, puis utilisée par un actionneur qui peut être commandé à distance par un transmetteur. Ceci représente par exemple un gros avantage pour l'application sur des oléoducs pour lesquels l'application du dispositif selon l'invention permet de supprimer les câblages pour l'alimentation, long parfois de plusieurs centaines de kilomètres.
Liste des figuresThanks to this, the realization of valves operated by autonomous generator is possible. Indeed, the low power required for the maneuver can be generated from the fluid or from the external environment, stored and then used by an actuator that can be controlled remotely by a transmitter. This represents for example a great advantage for the application on oil pipelines for which the application of the device according to the invention makes it possible to eliminate the wiring for the supply, sometimes sometimes several hundred kilometers long.

Exposé détaillé de l'utilisation du procédé selon l'inventionFigure 11 shows, exploded, another example of pressure loss device composed of balls (39). Detailed description of the use of the process according to the invention
La figure 1 décrit l'application préférée selon l'invention en position fermée, c'est-à-dire bloquant le passage du fluide. L'invention est constituée par un dispositif permettant de réaliser une perte de charge singulière variable et/ou la fermeture et l'étanchéité entre deux parties d'un circuit fluide. L'invention s'installe sur une conduite (1). Elle est constituée d'un corps (2a), fixé ici de façon démontable sur la conduite (1), portant, ici en porte-à-faux, une cartouche interne (3a). La fixation est faite par des vis (11).Figure 1 describes the preferred application according to the invention in the closed position, that is to say blocking the passage of the fluid. The invention consists of a device for achieving a variable singular pressure drop and / or closing and sealing between two parts of a fluid circuit. The invention is installed on a pipe (1). It consists of a body (2a), here detachably fixed on the pipe (1), carrying, here cantilevered, an inner cartridge (3a). Fixing is done by screws (11).
Cette cartouche (3a) est pour l'exemple fermée par un capot (25) qui permet les interventions de maintenance à l'intérieur de la cartouche (3a). Des ouvertures (6a) sont pratiquées à travers la cartouche (3a), à l'intérieur desquelles passe le fluide. Ces ouvertures sont pour l'exemple complétées de dispositifs de perte de charge composés d'un support (7) sur lequel sont fixées les plaques (33), (34), (35), (36) et (37). En passant à travers ce dispositif de perte de charge, le fluide perd de l'énergie. La figure 10 représente en détail ce dispositif de perte de charge. Le dispositif de perte de charge, sur la figure 1, est pour l'exemple fixé par des vis (13) sur la cartouche (3a). Les différentes plaques (33), (34), (35), (36) et (37) peuvent être montées et démontées sans démontage complet de la vanne. Ces plaques peuvent être adaptées à un écoulement particulier (nature du fluide, débit, pression, etc.). Le tube mobile (5), lorsqu'il coulisse, obture plus ou moins les ouvertures (6a) et donc les dispositifs de pertes de charge (7), faisant ainsi varier la perte de charge singulière que crée le dispositif sur l'écoulement. La forme des ouvertures (6a) peut aussi être adaptées en fonction des différentes applications. Lorsque le tube mobile (5) arrive en fin de course, il est en contact avec un siège (4), fixé pour l'exemple sur le support (2a) par des vis (12). Ce contact crée une étanchéité entre l'amont et l'aval du dispositif. Des butées (26) limitent la déformation du contact entre le siège (4) et le tube (5). Les figures 5a et 5b représentent en détail le rôle des butées (26). L'étanchéité ainsi créée est autoclave, c'est-à-dire que la pression amont applique une force sur le tube (5) allant dans le sens de la fermeture. Cette force peut être choisie par le rapport des surfaces du tube (5) et de son axe (18) soumises aux forces de pression amont et avaL Le tube (5) est poussé par un axe (18) guidé par un guidage (15) et
étanchéifié par un joint (14).This cartridge (3a) is for example closed by a cover (25) which allows maintenance operations inside the cartridge (3a). Openings (6a) are made through the cartridge (3a), within which the fluid passes. These openings are, for example, supplemented with pressure drop devices composed of a support (7) to which the plates (33), (34), (35), (36) and (37) are attached. By passing through this device for loss of charge, the fluid loses energy. Figure 10 shows in detail this pressure loss device. The pressure drop device, in Figure 1, is for example fixed by screws (13) on the cartridge (3a). The different plates (33), (34), (35), (36) and (37) can be mounted and disassembled without complete disassembly of the valve. These plates can be adapted to a particular flow (nature of the fluid, flow, pressure, etc.). The sliding tube (5), when it slides, more or less closes the openings (6a) and therefore the pressure drop devices (7), thereby varying the singular pressure drop that the device creates on the flow. The shape of the openings (6a) can also be adapted to different applications. When the movable tube (5) reaches the end of the stroke, it is in contact with a seat (4) fixed for the example on the support (2a) by screws (12). This contact creates a seal between the upstream and downstream of the device. Stops (26) limit the deformation of the contact between the seat (4) and the tube (5). Figures 5a and 5b show in detail the role of the stops (26). The seal thus created is autoclave, that is to say that the upstream pressure applies a force on the tube (5) going in the direction of closure. This force can be chosen by the ratio of the surfaces of the tube (5) and its axis (18) subjected to the upstream and downstream pressure forces. The tube (5) is pushed by an axis (18) guided by a guide (15). and sealed by a seal (14).
Le dispositif d'entraînement de l'axe (18) est pour l'exemple un système bielle (9a) et (9b) — manivelle (8), poussé par un actionneur (10).The drive device of the shaft (18) is for example a connecting rod system (9a) and (9b) - crank (8), pushed by an actuator (10).
Ce dispositif d'entraînement présente l'avantage d'être indépendant des variations de positionnement entre la cartouche (3 a) et le support (2a) dues par exemple aux dilations thermiques, aux forces de pression ou au poids de la cartouche (3a).This driving device has the advantage of being independent of the positioning variations between the cartridge (3a) and the support (2a) due for example to the thermal expansion, to the pressure forces or to the weight of the cartridge (3a). .
Lorsque Pactionneur (10) est désaccouplé du système bielle manivelle, l'ensemble de la cartouche (3a) et de toutes les pièces qu'elle porte, se démontent en un seul bloc après retrait des vis (11).When the actuator (10) is uncoupled from the crank system, all of the cartridge (3a) and all the parts that it carries, disassemble in one block after removal of the screws (11).
La figure 2 représente une variante de l'application préférée selon l'invention en position ouverte, c'est-à-dire engendrant une perte de charge minimale sur l'écoulement. Les ouvertures (6a) sont dans l'application préférée selon l'invention et pour l'exemple de forme rectangulaire, nues, et le déplacement du tube mobileFigure 2 shows a variant of the preferred application according to the invention in the open position, that is to say generating a minimal pressure drop on the flow. The openings (6a) are in the preferred application according to the invention and for the example of rectangular shape, bare, and the displacement of the moving tube
(5) fait varier la perte de charge engendrée sur le fluide lorsqu'il passe par les ouvertures (6a).(5) varies the pressure drop generated on the fluid as it passes through the openings (6a).
Le dispositif d'entraînement du tube (5) et de son axe (18) est une crémaillère (17) entraînée par un pignon (16) accouplé à un actionneur (29).The drive device of the tube (5) and its axis (18) is a rack (17) driven by a pinion (16) coupled to an actuator (29).
Une bride d'ouverture latérale (30) complète le support (2b) et permet l'accès à l'intérieur de la conduite (1) et du dispositif selon l'invention sans démontage total de ce dernier.A lateral opening flange (30) completes the support (2b) and allows access to the inside of the pipe (1) and the device according to the invention without total disassembly of the latter.
La cartouche (3b) ne comporte pas de capot de fermeture.The cartridge (3b) does not have a closure cap.
La figure 3 représente une variante de l'application selon l'invention en position ouverte.Figure 3 shows a variant of the application according to the invention in the open position.
Le support (2c) est ici de taille très réduite et la cartouche (3c) est interne à la conduite (1). Le dispositif d'entraînement du tube (5) et de son axe (18) est un vérin (19) commandé par un actionneur (22). Le fluide de commande est véhiculé dans des flexibles (20), rendant indépendant la position de la cartouche (3c) par rapport à la conduite (1).The support (2c) is here of very small size and the cartridge (3c) is internal to the pipe (1). The drive device of the tube (5) and its axis (18) is a jack (19) controlled by an actuator (22). The control fluid is conveyed in hoses (20), making the position of the cartridge (3c) independent with respect to the pipe (1).
Les ouvertures (6b) sont, pour l'exemple, de forme cylindrique.The openings (6b) are, for the example, of cylindrical shape.
La figure 4 représente une variante de l'application selon l'invention en position ouverte.Figure 4 shows a variant of the application according to the invention in the open position.
Le support (2d) est fixé de manière permanente à la conduite (1). Ce support
(2d) est de taille réduite et est interne à la conduite (1). Il supporte la cartouche (3d) qui porte un dispositif de génération autonome d'énergie composé d'une turbine (21) et d'un dispositif de stockage et d'actionnement (23). Le dispositif peut-être radiocommandé par le radiotransmetteur (24).The support (2d) is permanently fixed to the pipe (1). This support (2d) is of reduced size and is internal to the pipe (1). It supports the cartridge (3d) which carries an autonomous energy generation device consisting of a turbine (21) and a storage and actuating device (23). The device may be radio-controlled by the radiotransmitter (24).
Les supports percés (7) des dispositifs de perte de charge ont une taille inférieure aux ouvertures (6a). Ceci permet, en position ouverte, de n'engendrer que des pertes de charge minimes sur l'écoulement. Lorsque le tube (5) coulisse et commence à recouvrir Les supports percés (7), la perte de charge augmente plus rapidement. Cette disposition permet donc de ne créer qu'une perte de charge minime en pleine ouverture puis plus importante à partir d'une certaine course du tube (5).The drilled supports (7) of the pressure drop devices are smaller than the openings (6a). This allows, in the open position, to generate only minimal pressure losses on the flow. When the tube (5) slides and begins to cover the pierced brackets (7), the pressure drop increases more rapidly. This arrangement therefore makes it possible to create only a slight loss of pressure in full opening and then greater from a certain stroke of the tube (5).
Les figures 5a et 5b représentent des vues agrandies des organes de perte de charge et de fermeture du dispositif selon la figure 1. Les plaques (33), (34), (35), (36) et (37) ne sont ici pas représentées.FIGS. 5a and 5b show enlarged views of the pressure drop and closure members of the device according to FIG. 1. The plates (33), (34), (35), (36) and (37) are not here represented.
Ces figures permettent de mieux comprendre le fonctionnement des butées (26), qui limitent la déformation du contact cylindrique entre le siège (4) et le tube (5). En effet, le contact entre le tube (5) et le siège (4) se fait sur une surface faible et l'un ou l'autre du tube (5) ou du siège (4) est réalisé dans un matériau relativement mou. Sur la figure 5b, pour l'exemple, c'est le tube (5) qui est réalisé dans un matériau relativement mou et qui se déforme. Il y a une déformation importante sur la surface de contact qui risque de s'endommager. Cette déformation est néanmoins souhaitable pour assurer une bonne étanchéité.These figures make it possible to better understand the operation of the stops (26), which limit the deformation of the cylindrical contact between the seat (4) and the tube (5). Indeed, the contact between the tube (5) and the seat (4) is on a weak surface and one or the other of the tube (5) or the seat (4) is made of a relatively soft material. In Figure 5b, for the example, it is the tube (5) which is made of a relatively soft material and which is deformed. There is significant deformation on the contact surface that may be damaged. This deformation is nevertheless desirable to ensure a good seal.
Les butées (26), réalisées dans un matériau relativement dur, ne se déforment quasiment pas et fixent donc la valeur maximale de la déformation du tube (5), en limitant le déplacement du tube (5) par rapport au siège (4).The stops (26), made of a relatively hard material, do not deform almost and therefore set the maximum value of the deformation of the tube (5), limiting the movement of the tube (5) relative to the seat (4).
La figure 6 représente une variante de l'application selon l'invention en position ouverte.Figure 6 shows a variant of the application according to the invention in the open position.
Le support (2e) porte la cartouche (3e) de façon équilibrée et non plus en porte-à-faux comme dans les figures précédentes.The support (2e) carries the cartridge (3e) in a balanced manner and no longer cantilever as in the previous figures.

La figure 7 représente en vue de gauche coupée le support (2e) représenté dans la figure 6. Des secteurs sont découpés de manière à laisser passer le fluide.The actuator (10) pushes a toothed piece (27) which drives the tube (5) in translation through a rack (28). Figure 7 shows a left view cut off the support (2e) shown in Figure 6. Sectors are cut so as to let the fluid.
La figure 8 représente une variante de l'application selon l'invention en position ouverte.Figure 8 shows a variant of the application according to the invention in the open position.
Le support (2f) porte la cartouche (3f) de façon équilibrée et non plus en porte-à-faux comme dans les figures précédentes.The support (2f) carries the cartridge (3f) in a balanced manner and no longer cantilever as in the previous figures.
Le tube (5) est externe à la cartouche (3f). Le support (2f) est plein et le fluide passe à l'intérieur de la cartouche (3f), à travers les ouvertures (31),The tube (5) is external to the cartridge (3f). The support (2f) is solid and the fluid passes inside the cartridge (3f), through the openings (31),
(32) puis (6b).(32) then (6b).
La figure 9 représente en vue de gauche coupée le support (2f) représenté dans la figure 8. Ce support (2f) est plein de manière à forcer le passage du fluide par les ouvertures (31 ), (32) puis (6b).FIG. 9 is a left-side view of the support (2f) shown in FIG. 8. This support (2f) is solid so as to force the passage of the fluid through the openings (31), (32) and then (6b).
La figure 10 représente en détail un exemple de dispositif de perte de charge composé d'un support percé (7) ainsi que de grilles rainurées ou percés (33), (34), (35), (36) et (37), pour l'exemple au nombre de 5. Le trajet du fluide est représenté par la ligne épaisse fléchée.FIG. 10 shows in detail an example of a pressure drop device composed of a pierced support (7) as well as grooved or pierced grids (33), (34), (35), (36) and (37), for example the number of 5. The fluid path is represented by the thick arrow line.
La perte de charge est créée par le passage à travers les rainures et les trous du support (7) et des grilles (33), (34), (35), (36) et (37). La variation du coefficient de perte de charge de l'application selon l'invention est obtenue par l'obturation par le tube (5) d'un nombre variable de trous sur le support percé (7).The pressure drop is created by passing through the grooves and holes of the support (7) and grids (33), (34), (35), (36) and (37). The variation of the pressure drop coefficient of the application according to the invention is obtained by the closure by the tube (5) of a variable number of holes on the pierced support (7).
Le dispositif de perte de charge est aussi adaptable à un écoulement donné (nature du fluide, débit, pression, etc.) par la modulation, hors fonctionnement, du nombre et du positionnement des trous et ramures sur le support (7) et les grilles (33), (34), (35), (36) et (37)^ par la variation du nombre et de l'ordre des grilles, et enfin par la variation de la forme générale et de la nature des grilles et du support (7). Le nombre de dispositifs de perte de charge peut également être modulé puisqu'un ou plusieurs dispositifs de perte de charge peut être tout simplement enlevé ou bien remplacé par une plaque pleine. Ceci permet, par exemple, de linéariser la perte de charge en fonction du déplacement du tube (5).The pressure drop device is also adaptable to a given flow (nature of the fluid, flow rate, pressure, etc.) by the modulation, out of operation, of the number and positioning of the holes and branches on the support (7) and the grids (33) (34) (35) (36) and (37) ^ by varying the number and order of the gates, and finally the variation of the general shape and nature of the grids and support (7). The number of pressure drop devices can also be modulated since one or more pressure drop devices can simply be removed or replaced by a solid plate. This makes it possible, for example, to linearize the pressure drop as a function of the displacement of the tube (5).
La position régulation correspond au positionnement du tube (5) en face du support (7).
Pour permettre la variation de la perte de charge en position ouverte (hors régulation), le support (7) et les grilles (33), (34), (35), (36) et (37) peuvent être remplacés par des éléments de tailles différentes ayant la même fonction. Ceci permet d'adapter la perte de charge minimale lorsque le dispositif est en position ouverte. Sur la figure 10, pour l'exemple, le support (7) et les grilles (33), (34), (35), (36) et (37) sont de taille inférieure à l'ouverture (6a) de la cartouche (3a).The regulation position corresponds to the positioning of the tube (5) opposite the support (7). To allow the variation of the pressure drop in the open position (out of regulation), the support (7) and the grids (33), (34), (35), (36) and (37) can be replaced by elements of different sizes having the same function. This makes it possible to adapt the minimum pressure drop when the device is in the open position. In FIG. 10, for the example, the support (7) and the grids (33), (34), (35), (36) and (37) are smaller than the opening (6a) of the cartridge (3a).
Cette disposition permet une régulation entre zéro et cent pourcent du débit. Le montage et le démontage de ces dispositifs de perte de charge se font hors fonctionnement et indépendamment les uns des autres, mais sans démontage complet de la cartouche (3a). En effet, lorsque le tube (5) est en position ouverte, le support (7) peut être facilement démonté par le démontage des vis (13).This arrangement allows a regulation between zero and one hundred percent of the flow. The assembly and disassembly of these pressure drop devices are done out of operation and independently of each other, but without complete disassembly of the cartridge (3a). Indeed, when the tube (5) is in the open position, the support (7) can be easily disassembled by removing the screws (13).
La figure 11 représente en détail un autre exemple de dispositif de perte de charge composé d'un support percé (7) sur lequel est fixée une boîte (38) remplit de billes (39) et fermée par une plaque ajourée (40), Le fluide, en passant à travers les billes (39) comme représenté par la ligne épaisse fléchée, perd de l'énergie. Le diamètre des billes (39) ainsi que les dimensions de la boite (38) peuvent être modulés de manière à faire varier la perte de charge engendrée sur le fluide, à adapter le dispositif à un écoulement donné (nature du fluide, débit, pression, etc.) et éventuellement à linéariser la perte de charge en fonction du déplacement du tube (5).
FIG. 11 shows in detail another example of a pressure drop device composed of a pierced support (7) on which is fixed a box (38) filled with balls (39) and closed by a perforated plate (40), fluid, passing through the balls (39) as represented by the thick arrow line, loses energy. The diameter of the balls (39) and the dimensions of the box (38) can be modulated so as to vary the pressure drop generated on the fluid, to adapt the device to a given flow (nature of the fluid, flow, pressure , etc.) and optionally to linearize the pressure drop as a function of the displacement of the tube (5).
