Abstract

The invention relates to a system for transporting a fluid (gas, oil) comprising a valve (1) integral with a first rotating spindle (1a), and an actuator driving in rotation a second rotating spindle (2a). The actuator (2), which is controlled by a control circuit, actuates the valve (1) into open or closed position. The invention concerns an interposed device (9) for self-disengaging control of valves enabling to trouble-shoot the circuit control and/or the actuator (2) and or the valve (1). Said interposed device (9) comprises a mechanism for: disengaging the rotating spindle of the valve (1) from the rotating spindle (2a) of the actuator (2), manoeuvring the valve (1) into open or close position, coupling or preparing for automatic disengagement the rotating spindle (1a) of the valve (1) to the rotation shaft (2a) of the actuator (2), after the valve (1) has been manoeuvred into the required position. Thus, the trouble-shooting only requires one trip to the site of the valve.

Description

Procédé et dispositif de commande débrayable pour vannes- La présente invention concerne un procédé et un dispositif de commande débrayable pour vannes. The present invention relates to a disengageable control method and device for valves.
Dans le domaine des circuits de transport de fluides, notamment du transport de gaz ou de pétrole, il est nécessaire de pouvoir isoler des parties d'un circuit en cas de dysfonctionnement ou de panne. Pour répondre à cette nécessité, on utilise des vannes qui permettent d'arrêter la circulation du fluide dans le circuit de transport. Ces vannes sont généralement manœuvrées en position ouverte, fermée ou intermédiaire par un servomoteur ou "actionneur", lui-même piloté à distance.In the field of fluid transport circuits, in particular the transport of gas or oil, it is necessary to be able to isolate parts of a circuit in the event of a malfunction or breakdown. To meet this need, valves are used which stop the circulation of the fluid in the transport circuit. These valves are generally operated in the open, closed or intermediate position by a servomotor or "actuator", itself remotely controlled.
Les dysfonctionnements ou pannes susceptibles d'affecter un circuit de transport de fluides nécessitent toutefois de manœuvrer manuellement les vannes, pour permettre le dépannage du circuit.Malfunctions or breakdowns likely to affect a fluid transport circuit, however, require manual operation of the valves, to allow troubleshooting of the circuit.
A l'heure actuelle, les vannes motorisées sont, en principe, équipées d'une commande de secours qui permet de les manœuvrer manuellement en position ouverte, fermée ou intermédiaire. En cas de dysfonctionnement, un technicien doit se rendre sur le site de la vanne. Au moyen d'un volant, il actionne une vis sans fin qui entraîne la rotation de l'axe de l'actionneur et de l'axe de la vanne. Ainsi il ouvre ou ferme la vanne manuellement mais, lors de la remise en service du circuit, la vanne demeure bloquée de manière irréversible en position ouverte, fermée ou intermédiaire. La remise en service ultérieure de l'actionneur par envoi de fluide moteur dans ses circuits ne produit aucun effet car son axe de rotation est bloqué. La vanne reste dans la position qu'elle occupe. Dès lors, le technicien doit se rendre une nouvelle fois sur le site de la vanne et tourner le volant dans l'autre sens afin de dégager la vis sans fin. L'actionneur peut alors de nouveau fonctionner par l'envoi de fluide moteur.At present, motorized valves are, in principle, equipped with an emergency control which allows them to be operated manually in the open, closed or intermediate position. In the event of a malfunction, a technician must go to the valve site. By means of a handwheel, it actuates an endless screw which drives the rotation of the actuator axis and the valve axis. Thus it opens or closes the valve manually but, when the circuit is put back into service, the valve remains irreversibly blocked in the open, closed or intermediate position. The subsequent return to service of the actuator by sending working fluid into its circuits has no effect because its axis of rotation is blocked. The valve remains in the position it occupies. From then on, the technician must go once again to the site of the valve and turn the handwheel in the other direction in order to release the worm. The actuator can then operate again by sending working fluid.
Si l'on envisage d'améliorer les commandes de secours existantes à l'heure actuelle, en vue de faciliter le dépannage d'un circuit, il est impératif de concevoir une solution qui puisse respecter les infrastructures existantes. En raison du coût représenté, c'est à la commande de secours de s'adapter au circuit existant et non l'inverse.If you plan to improve the existing emergency controls to facilitate troubleshooting of a circuit, it is imperative to design a solution that can respect existing infrastructure. Because of the cost represented, it is up to the emergency control to adapt to the existing circuit and not the reverse.
La solution, afin que le technicien n'ait plus qu'un seul déplacement à effectuer sur le site de la vanne, consiste à substituer à la commande de secours existante un dispositif intercalaire de commande manuelle débrayable et réembrayable automatiquement.The solution, so that the technician only has to make one trip to the valve site, consists in replacing the existing emergency control with an intermediate manual control device that can be disengaged and re-clutched automatically.
Ainsi conçue comme une simple substitution d'une pièce par une autre, l'installation de ce dispositif intercalaire peut être effectuée à moindre coût aussi bien sur un circuit existant que sur un circuit nouveau.Thus conceived as a simple substitution of one part by another, the installation of this intermediate device can be carried out at lower cost both on an existing circuit than on a new circuit.
L'invention s'applique à un système pour transporter un fluide, notamment du gaz ou du pétrole. Ce système comprend une vanne solidaire d'un premier axe de rotation et un actionneur qui entraîne en rotation un second axe de rotation et qui actionne la vanne en position ouverte, fermée ou intermédiaire. L'actionneur est contrôlé par un circuit de commande.The invention applies to a system for transporting a fluid, in particular gas or petroleum. This system comprises a valve integral with a first axis of rotation and an actuator which rotates a second axis of rotation and which actuates the valve in the open, closed or intermediate position. The actuator is controlled by a control circuit.
L'invention concerne un dispositif intercalaire de secours pour manœuvrer la vanne en cas de panne dudit circuit de commande et/ou dudit actionneur et/ou de ladite vanne. Ledit dispositif intercalaire est destiné à se substituer à la liaison mécanique située entre l'actionneur et la vanne.The invention relates to an emergency interlayer device for operating the valve in the event of failure of said control circuit and / or of said actuator and / or of said valve. Said intermediate device is intended to replace the mechanical connection located between the actuator and the valve.
Ainsi, l'installation dudit dispositif intercalaire peut être effectuée sur un système de transport de fluide existant.Thus, the installation of said intermediate device can be carried out on an existing fluid transport system.
Ledit dispositif intercalaire peut également être installé entre l'actionneur et la vanne en lieu et place de la liaison mécanique.Said intermediate device can also be installed between the actuator and the valve in place of the mechanical connection.
Ledit dispositif intercalaire comprend un mécanisme actionnable par un technicien.Said intermediate device comprises a mechanism operable by a technician.
Ce mécanisme permet tout d'abord de désaccoupler ledit premier axe de rotation de la vanne dudit second axe de rotation de l'actionneur, afin que la manœuvre de la vanne puisse être effectuée manuellement, indépendamment de l'actionneur, après le désaccouplement automatique du servomoteur.This mechanism firstly makes it possible to decouple said first axis of rotation from the valve from said second axis of rotation of the actuator, in order to that the valve can be operated manually, independently of the actuator, after the automatic decoupling of the actuator.
Ce mécanisme permet ensuite de manœuvrer manuellement la vanne en position ouverte, fermée ou intermédiaire, selon la position requise.This mechanism then makes it possible to manually operate the valve in the open, closed or intermediate position, depending on the required position.
Ce mécanisme permet enfin d'accoupler à nouveau ou de mettre en attente d'accouplement automatique ledit premier axe de rotation de la vanne et ledit second axe de rotation de l'actionneur, après que la vanne aura été manœuvrée dans la position requise. Ainsi, il n'est pas nécessaire que le technicien retourne sur le site de la vanne après dépannage pour ouvrir ou fermer celle-ci, puisque l 'actionneur actionne de nouveau la vanne, grâce au dispositif de réembrayage automatique.This mechanism finally makes it possible to couple again or to put on hold for automatic coupling said first axis of rotation of the valve and said second axis of rotation of the actuator, after the valve has been operated in the required position. Thus, it is not necessary for the technician to return to the site of the valve after troubleshooting to open or close it, since the actuator actuates the valve again, thanks to the automatic re-clutch device.
De préférence, pour désaccoupler ou accoupler ledit premier axe de rotation de la vanne et ledit second axe de rotation de l 'actionneur, ledit mécanisme comprend des premiers moyens d'accouplement audit premier axe de rotation de ladite vanne. Lesdits premiers moyens d'accouplement comprennent des cannelures, ou un autre moyen, mobiles en translation. Ledit mécanisme comprend également des seconds moyens d'accouplement audit second axe de rotation de l 'actionneur. Lesdits seconds moyens d'accouplement comprennent des tenons coopérant avec des mortaises.Preferably, for uncoupling or coupling said first axis of rotation of the valve and said second axis of rotation of the actuator, said mechanism comprises first means of coupling to said first axis of rotation of said valve. Said first coupling means comprise grooves, or another means, movable in translation. Said mechanism also comprises second coupling means to said second axis of rotation of the actuator. Said second coupling means comprise tenons cooperating with mortises.
Avantageusement, selon une variante de réalisation, lesdits tenons et lesdites mortaises ont une forme conique. De préférence, selon l'invention, les moyens d'accouplement sont actionnés par un technicien au moyen d'un levier.Advantageously, according to an alternative embodiment, said tenons and said mortises have a conical shape. Preferably, according to the invention, the coupling means are actuated by a technician by means of a lever.
De préférence, selon l'invention, pour manœuvrer la vanne en position ouverte, fermée ou intermédiaire, ledit mécanisme comporte un moyen de commande actionnable par le technicien, pour entraîner en rotation ledit premier axe de rotation de ladite vanne.Preferably, according to the invention, to operate the valve in the open, closed or intermediate position, said mechanism comprises a control means operable by the technician, to drive in rotation of said first axis of rotation of said valve.
De préférence, selon l'invention, ledit moyen de commande est composé dudit levier monté sur rotule.Preferably, according to the invention, said control means is composed of said lever mounted on a ball joint.
L'invention concerne également un procédé pour dépanner ledit circuit de commande et/ou ledit actionneur et/ou ladite vanne. Le procédé est réalisé au moyen d'un mécanisme actionnable par un technicien.The invention also relates to a method for troubleshooting said control circuit and / or said actuator and / or said valve. The process is carried out by means of a mechanism operable by a technician.
Le procédé, selon l'invention, comprend plusieurs étapes.The method according to the invention comprises several steps.
Il comprend l'étape de désaccoupler ledit premier axe de rotation de la vanne dudit second axe de rotation de l 'actionneur. Ainsi, la manœuvre de la vanne peut être effectuée manuellement, indépendamment de l 'actionneur.It comprises the step of uncoupling said first axis of rotation from the valve from said second axis of rotation of the actuator. Thus, the operation of the valve can be carried out manually, independently of the actuator.
Il comprend également l 'étape de manœuvrer la vanne en position ouverte, fermée ou intermédiaire, selon la position requise.It also includes the step of operating the valve in the open, closed or intermediate position, depending on the required position.
Il comprend enfin l 'étape d'accoupler ou de mettre en attente d'accouplement automatique ledit premier axe de rotation de la vanne audit second axe de rotation de l'actionneur, après que la vanne aura été manœuvrée dans la position requise.Finally, it comprises the step of coupling or putting on hold for automatic coupling said first axis of rotation of the valve to said second axis of rotation of the actuator, after the valve has been operated in the required position.
Ainsi, il n'est pas nécessaire que le technicien retourne sur le site de la vanne après dépannage pour ouvrir ou fermer celle-ci, puisque l'actionneur actionne de nouveau la vanne.Thus, it is not necessary for the technician to return to the valve site after troubleshooting to open or close it, since the actuator actuates the valve again.
De préférence, pour accoupler ou désaccoupler ledit premier a e de rotation de la vanne et ledit second axe de rotation de l'actionneur, le procédé, selon l'invention, comprend plusieurs étapes.Preferably, for coupling or uncoupling said first rotation axis of the valve and said second axis of rotation of the actuator, the method according to the invention comprises several stages.
Le procédé comprend l 'étape de rapprocher ou d'écarter l 'une de l'autre des pièces d'entraînement par tenons et mortaises, l'une au moins des pièces d'entraînement étant solidaire dudit second axe de rotation de l'actionneur.The method comprises the step of bringing one or the other of the drive parts by tenons and mortises, at least one of the drive parts being integral with said second axis of rotation of the actuator .
Il comprend également l 'étape de translater l 'une par rapport à l 'autre des pièces d'entraînement comportant des cannelures, l'une au moins des pièces d'entraînement étant solidaire dudit premier axe de rotation de ladite vanne.It also includes the step of translating one with respect to the other of the drive parts comprising grooves, at least one of the drive parts being integral with said first axis of rotation of said valve.
Avantageusement, lesdites pièces d'entraînement par tenons et mortaises ont une forme conique. De préférence, selon l'invention, pour manœuvrer la vanne en position ouverte, fermée ou intermédiaire, on actionne un levier en prise avec ledit premier axe de rotation de la vanne.Advantageously, said tenon and mortise drive parts have a conical shape. Preferably, according to the invention, to operate the valve in the open, closed or intermediate position, a lever is actuated in engagement with said first axis of rotation of the valve.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description de variantes de réalisation de l 'invention, données à titre d'exemple indicatif et non limitatif, et de : la figure 1 qui représente le dispositif intercalaire de commande en position embrayée (l'axe de rotation de la vanne et l'axe de rotation de l'actionneur sont accouplés) et la figure 2 qui représente le dispositif intercalaire de commande en position débrayée (l'axe de rotation de la vanne et l'axe de rotation de l 'actionneur sont désaccouplés).Other characteristics and advantages of the invention will appear on reading the description of alternative embodiments of the invention, given by way of non-limiting example, and from: FIG. 1 which represents the intermediate control device in the engaged position (the axis of rotation of the valve and the axis of rotation of the actuator are coupled) and FIG. 2 which represents the intermediate control device in the disengaged position (the axis of rotation of the valve and the the axis of rotation of the actuator are uncoupled).
On précisera que les éléments qui sont hachurés de la même manière sont solidaires les uns des autres.It will be noted that the elements which are hatched in the same way are integral with each other.
L'invention s'applique à un système pour transporter un fluide (gaz, pétrole). Ce système comprend une vanne 1 solidaire d'un premier axe de rotation la et un actionneur 2 qui entraîne en rotation un second axe de rotation 2a. L'actionneur 2 actionne l'obturateur de la vanne 1 en rotation.The invention applies to a system for transporting a fluid (gas, oil). This system comprises a valve 1 integral with a first axis of rotation la and an actuator 2 which rotates a second axis of rotation 2a. The actuator 2 actuates the valve shutter 1 in rotation.
Il est lui-même contrôlé à distance au moyen d'un circuit de commande.It is itself remotely controlled by means of a control circuit.
Entre l'actionneur 2 et la vanne 1 est installé un dispositif intercalaire 9, prenant appui sur l'embase l b de la vanne 1. Ce dispositif 9 vient remplacer une liaison mécanique amovible, habituellement installée entre l 'actionneur 2 et la vanne 1. Ainsi, le dispositif intercalaire 9 peut être installé aussi bien sur un circuit de transport de fluides préexistant que sur un nouveau circuit. Le dispositif intercalaire 9 comprend un mécanisme actionnable par un technicien. Ce mécanisme comprend un baladeur mobile 7, commandé par un levier 6. Le baladeur 7 comporte des moyens d'accouplement à l'axe de rotation la de la vanne 1 au moyen de cannelures 3a solidaires d'un corps 10, dans lesquelles coulissent des cannelures 3b, solidaires du baladeur mobile 7. Le baladeur mobile 7 comporte également des moyens d'accouplement à l'axe de rotation 2a de l'actionneur 2. L'axe de rotation 2a de l'actionneur 2 comprend un tenon conique 4 qui s'emboîte dans une mortaise 5 du baladeur mobile 7. Un ressort de rappel 8 maintient par pression le baladeur mobile 7 en position haute, c'est-à-dire accouplé à l'axe de rotation 2a de l'actionneur 2.Between the actuator 2 and the valve 1 is installed an intermediate device 9, bearing on the base lb of the valve 1. This device 9 replaces a removable mechanical connection, usually installed between the actuator 2 and the valve 1. Thus, the intermediate device 9 can be installed both on a pre-existing fluid transport circuit as on a new circuit. The intermediate device 9 comprises a mechanism operable by a technician. This mechanism comprises a mobile player 7, controlled by a lever 6. The player 7 includes means for coupling to the axis of rotation of the valve 1 by means of grooves 3a secured to a body 10, in which slide splines 3b, integral with the mobile player 7. The mobile player 7 also includes means for coupling to the axis of rotation 2a of the actuator 2. The axis of rotation 2a of the actuator 2 comprises a conical pin 4 which fits into a mortise 5 of the mobile player 7. A return spring 8 maintains by pressure the mobile player 7 in the high position, that is to say coupled to the axis of rotation 2a of the actuator 2.
Lorsque le circuit de transport de fluides fonctionne sans anomalies, l'axe de rotation 2a de l'actionneur 2 est accouplé à l'axe de rotation la de la vanne 1 , ainsi qu'on l'a représenté sur la figure 1. La manœuvre de la vanne 1 est ainsi commandée par l'actionneur 2.When the fluid transport circuit operates without anomalies, the axis of rotation 2a of the actuator 2 is coupled to the axis of rotation la of the valve 1, as shown in FIG. 1. The operation of valve 1 is thus controlled by actuator 2.
Lorsqu'un dysfonctionnement ou une panne quelconque survient, il est nécessaire de pouvoir conserver le contrôle de l 'ouverture et de la fermeture de la vanne 1, alors même que le fonctionnement du circuit en mode automatique n'est plus opérationnel. Il faut alors se rendre sur le site de la vanne 1.When any malfunction or breakdown occurs, it is necessary to be able to maintain control of the opening and closing of valve 1, even though the operation of the circuit in automatic mode is no longer operational. You must then go to the site of valve 1.
Lorsqu'on exerce une pression sur le levier 6 vers le haut, cela a pour effet de faire translater le baladeur 7 vers le bas. Les cannelures 3a et 3 b coulissent les unes par rapport aux autres. Le mécanisme est débrayé. L'axe de rotation 2a de l 'actionneur 2 se trouve alors désolidarisé de l 'axe de rotation la de la vanne 1. On peut ensuite, en manœuvrant le levier 6 horizontalement, faire pivoter le corps 10 autour de l'axe 11 du dispositif intercalaire 9. Le corps 10 est en prise avec l'axe de rotation la de la vanne 1, via les cannelures 3a et 3b, respectivement solidaires du corps 10 et de l'axe de rotation la de la vanne 1. L'axe de rotation la de la vanne 1 pivote ainsi indépendamment de l'axe de rotation 2a de l 'actionneur 2. On peut ainsi manuellement et selon la position requise manœuvrer la vanne 1 en position ouverte, fermée ou intermédiaire.When pressure is exerted on the lever 6 upwards, this has the effect of causing the player 7 to translate downwards. The grooves 3a and 3b slide relative to each other. The mechanism is disengaged. The axis of rotation 2a of the actuator 2 is then disconnected from the axis of rotation of the valve 1. It is then possible, by operating the lever 6 horizontally, to pivot the body 10 around the axis 11 of the intermediate device 9. The body 10 is engaged with the axis of rotation la of the valve 1, via the grooves 3a and 3b, respectively integral with the body 10 and the axis of rotation la of the valve 1. The axis of rotation of valve 1 thus pivots independently of the axis of rotation 2a of the actuator 2. It is thus possible manually and according to the required position to operate the valve 1 in the open, closed or intermediate position.
Dès lors que la vanne 1 a été manœuvrée dans la position requise, on relâche la pression sur le levier 6. Grâce à l 'action du ressort de rappel 8, le baladeur mobile 7 reprend sa position haute. L'axe de rotation la de la vanne 1 et l'axe de rotation 2a de l'actionneur 2 sont ainsi ré-accouplés. Lorsque l'actionneur 2 sera de nouveau actionné par envoi d'air comprimé, il entraînera en rotation l'axe de rotation la de la vanne 1. Le circuit de transport de fluides retrouvera ainsi son fonctionnement automatique.As soon as the valve 1 has been operated in the required position, the pressure is released on the lever 6. Thanks to the action of the return spring 8, the mobile player 7 returns to its high position. The axis of rotation la of the valve 1 and the axis of rotation 2a of the actuator 2 are thus re-coupled. When the actuator 2 is again actuated by sending compressed air, it will rotate the axis of rotation of the valve 1. The fluid transport circuit will thus resume its automatic operation.
Dans le cas où l'actionneur 2 est en position "vanne ouverte" alors que l'axe de rotation la de la vanne 1 est en position "vanne fermée", ou inversement, le fonctionnement automatique ne sera à nouveau opérationnel qu'après une rotation d'un quart de tour de l'axe de rotationIn the case where the actuator 2 is in the "open valve" position while the axis of rotation of the valve 1 is in the "closed valve" position, or vice versa, the automatic operation will only be operational again after a quarter-turn rotation of the axis of rotation
2a de l 'actionneur 2 (rotation nécessaire pour que la position de l'actionneur 2 coïncide à nouveau avec celle de la vanne 1 ).2a of the actuator 2 (rotation necessary so that the position of the actuator 2 again coincides with that of the valve 1).
Ainsi, le mécanisme, selon l'invention, présente l'avantage de ne nécessiter qu'un seul déplacement sur le site de la vanne 1 en cas de dysfonctionnement du circuit de transport de fluides ou du circuit d'asservissement et de commande de l'actionneur 2.
