Description

Obturateur en ligne comportant une plaque d’obturation configurée pour être indexée en position  In-line shutter having a shutter plate configured to be indexed in position
La présente invention concerne le domaine des installations pour la production, le traitement ou le transport d’un fluide dans au moins une canalisation. Un tel fluide peut notamment être un liquide, un gaz, un produit sous forme pâteuse ou un produit à l’état de poudre. The present invention relates to the field of installations for the production, treatment or transport of a fluid in at least one pipe. Such a fluid can in particular be a liquid, a gas, a product in pasty form or a product in the powder state.
Plus précisément, l’invention se rapporte au domaine des obturateurs en ligne comportant une plaque d’obturation mobile dans un plan P et étant destinés à être montés sur une telle canalisation pour par exemple effectuer une opération de maintenance sur un organe agencé en aval de cet obturateur en ligne. More specifically, the invention relates to the field of in-line shutters comprising a shutter plate movable in a plane P and being intended to be mounted on such a pipe, for example for performing a maintenance operation on a member arranged downstream of this shutter online.
De façon connue, de tels obturateurs en ligne ont notamment été décrits par le Demandeur dans le document FR 3057 933. De tels obturateurs en ligne comportent ainsi généralement une plaque d’obturation monolithique en métal apte à réaliser une obturation étanche ou une circulation fluidique dans la canalisation. Un organe de suivi peut être solidarisé de manière rigide avec la plaque d’obturation. Cet organe de suivi est alors agencé de manière déportée latéralement par rapport à la plaque d’obturation et peut permettre de réaliser un indexage en position de la plaque d’obturation par rapport à un corps de l’obturateur au moyen d’un organe d’indexage solidarisé avec le corps. Cependant, un tel assemblage rigide entre la plaque d’obturation et l’organe de suivi peut se révéler problématique pour réaliser un indexage en position qui soit simple et rapide à mettre en œuvre manuellement par un opérateur actionnant la plaque d’obturation. En effet, un tel indexage en position ne peut être obtenu qu’en positionnant précisément en regard un doigt d’indexage de l’organe d’indexage avec un alésage de forme sensiblement complémentaire ménagé dans l’organe de suivi. In known manner, such in-line shutters have in particular been described by the Applicant in document FR 3057 933. Such in-line shutters thus generally comprise a monolithic shutter plate made of metal capable of producing a tight shutter or a fluid circulation in the pipeline. A follow-up member can be rigidly secured to the closure plate. This monitoring member is then arranged in a laterally offset manner relative to the shutter plate and may allow indexing in position of the shutter plate relative to a body of the shutter by means of a shutter member. indexing secured to the body. However, such a rigid assembly between the closure plate and the monitoring member may prove to be problematic for carrying out indexing in position which is simple and rapid to implement manually by an operator actuating the closure plate. Indeed, such indexing in position cannot be obtained by precisely positioning an indexing finger of the indexing member with a bore of substantially complementary shape made in the monitoring member.
Or, la plaque d’obturation présente généralement un jeu important de fonctionnement par rapport au corps de l’obturateur. Ainsi, le guidage de la plaque d’obturation et donc également de l’organe de suivi solidaire de la plaque d’obturation est peu précis par rapport au corps de l’obturateur. However, the shutter plate generally has a large clearance of operation relative to the body of the shutter. Thus, the guidance of the shutter plate and therefore also of the monitoring member integral with the shutter plate is imprecise with respect to the body of the shutter.
La présente invention a alors pour objet de proposer un obturateur en ligne permettant de s’affranchir des limitations mentionnées ci-dessus. En effet, un but de l’invention est de fournir une solution optimale pour permettre un indexage en positon simple et rapide d’une plaque d’obturation avec un corps d’obturateur. The object of the present invention is therefore to propose an on-line shutter making it possible to overcome the limitations mentioned above. Indeed, an object of the invention is to provide an optimal solution to allow indexing in simple and rapid position of a closure plate with a shutter body.
Comme déjà évoqué, l’invention concerne un obturateur en ligne permettant de réaliser une obturation étanche, et inversement, une circulation fluidique dans une canalisation entre une conduite amont agencée en amont de l’obturateur en ligne selon un sens de circulation fluidique et une conduite aval agencée en aval de l’obturateur en ligne selon le sens de circulation fluidique, l’obturateur en ligne comportant : As already mentioned, the invention relates to an in-line shutter making it possible to produce a sealed shutter, and conversely, a fluid circulation in a pipe between an upstream pipe arranged upstream of the inline shutter in a direction of fluid flow and a pipe downstream arranged downstream of the in-line shutter in the direction of fluid flow, the in-line shutter comprising:

Selon l’invention, un tel obturateur en ligne est remarquable en ce qu’il comporte des moyens de guidage configurés pour guider indépendamment des mouvements de l’organe de suivi par rapport au corps lors des déplacements relatifs de la plaque d’obturation par rapport au corps et en ce que la plaque d’obturation coopère avec l’organe de suivi selon une liaison mécanique de type présentant au moins un deg ré de liberté. According to the invention, such an in-line shutter is remarkable in that it comprises guide means configured to guide independently of the movements of the tracking member relative to the body during the relative movements of the plate. shutter relative to the body and in that the shutter plate cooperates with the monitoring member according to a mechanical connection of the type having at least one deg re of freedom.
Autrement dit grâce aux moyens de guidage, le guidage de l’organe de suivi par rapport au corps peut être dissocié du guidage de la plaque d’obturation par rapport au corps. De plus, l’organe de suivi présente alors une capacité de déplacement relative par rapport à la plaque d’obturation pour permettre d’éventuelles variations de guidage entre l’organe de suivi et la plaque de guidage. In other words, thanks to the guide means, the guide of the tracking member with respect to the body can be dissociated from the guide of the closure plate with respect to the body. In addition, the tracking member then has a relative displacement capacity relative to the closure plate to allow possible variations in guidance between the tracking member and the guide plate.
En outre, la plaque d’obturation et l’organe de suivi peuvent décrire différents types de mouvements par rapport au corps de l’obturateur. De tels mouvements peuvent par exemple être choisis parmi le groupe comportant les mouvements de translation dans le plan P et les mouvements de rotation dans le plan P. In addition, the shutter plate and the tracking device can describe different types of movement relative to the shutter body. Such movements can for example be chosen from the group comprising the translational movements in the plane P and the rotational movements in the plane P.
Ainsi selon un premier exemple de réalisation de l’invention, les moyens de guidage peuvent être configurés pour guider en translation les mouvements de l’organe de suivi par rapport au corps. Selon ce premier exemple de réalisation, pour réaliser un tel guidage en translation, les moyens de guidage peuvent comporter des paliers réalisés dans un matériau à faible coefficient de frottement tel que par exemple du Polytétrafluoroéthylène (PTFE) ou encore du bronze autolubrifiant. De tels moyens de guidage peuvent également comporter des roulements ou douilles présentant des éléments roulants à billes, à rouleaux ou à aiguilles permettant de réaliser un roulement sans frottement lors des mouvements de translation relatifs entre l’organe de suivi et le corps ou toute autre pièce solidaire ou rapportée sur le corps. Selon un second exemple de réalisation de l’invention, les moyens de guidage peuvent être configurés pour guider en rotation les mouvements de l’organe de suivi par rapport au corps. Thus according to a first embodiment of the invention, the guide means can be configured to guide in translation the movements of the tracking member relative to the body. According to this first exemplary embodiment, to achieve such translational guidance, the guide means may include bearings made of a material with a low coefficient of friction such as for example Polytetrafluoroethylene (PTFE) or even self-lubricating bronze. Such guide means may also include bearings or sockets having rolling elements with balls, rollers or needles making it possible to produce a frictionless bearing during relative translational movements between the tracking member and the body or any other part. united or attached to the body. According to a second embodiment of the invention, the guide means can be configured to guide the movements of the tracking member in rotation relative to the body.
De même selon ce second exemple de réalisation pour réaliser un tel guidage en rotation les moyens de guidage peuvent comporter des paliers réalisés dans un matériau à faible coefficient de frottement tel que par exemple du Polytétrafluoroéthylène (PTFE) ou encore du bronze autolubrifiant. De tels moyens de guidage peuvent également comporter des roulements ou douilles présentant des éléments roulants à billes, à rouleaux ou à aiguilles permettant de réaliser un roulement sans frottement lors des mouvements de rotation relatifs entre l’organe de suivi et le corps ou toute autre pièce solidaire ou rapportée sur le corps. Similarly, according to this second embodiment to achieve such rotational guidance, the guide means may include bearings made of a material with a low coefficient of friction such as for example Polytetrafluoroethylene (PTFE) or even self-lubricating bronze. Such guide means may also include bearings or bushings having rolling elements with balls, rollers or needles making it possible to produce a rolling without friction during relative rotational movements between the tracking member and the body or any other part. united or attached to the body.
Avantageusement, les moyens de guidage peuvent comporter au moins une pièce de guidage solidarisée avec le corps, la (ou les) pièce(s) de guidage présentant un orifice au travers duquel l’organe de suivi est apte à se déplacer avec un jeu de guidage adapté. Advantageously, the guide means can comprise at least one guide piece secured to the body, the guide piece (s) having an orifice through which the tracking member is able to move with a set of adapted guidance.
En d’autres termes, l’orifice de la (ou des) pièce(s) de guidage et l’organe de suivi comportent des formes complémentaires permettant de limiter les degrés de liberté à une direction en translation correspondant au premier exemple de réalisation ou à une direction en rotation correspondant au second exemple de réalisation. Par ailleurs selon une première variante de l’invention, l’organe d’indexage peut être solidarisé avec la (ou les) pièce(s) de guidage. In other words, the orifice of the guide piece (s) and the monitoring member comprise complementary shapes making it possible to limit the degrees of freedom to a direction in translation corresponding to the first exemplary embodiment or to a rotating direction corresponding to the second embodiment. Furthermore, according to a first variant of the invention, the indexing member can be secured to the guide piece (s).
Ainsi selon cette première variante de l’invention, l’organe d’indexage et la (ou les) pièce(s) de guidage sont agencés en liaison de type encastrement et ne présentent aucun degré de liberté l’un par rapport à l’autre. Thus, according to this first variant of the invention, the indexing member and the guide piece (s) are arranged in built-in type connection and have no degree of freedom from each other.
Selon une seconde variante de l’invention, l’obturateur peut comporter des moyens de serrage/écartement permettant de serrer, et inversement, d’écarter les demi-corps amont et aval par rapport à la plaque d’obturation pour permettre un serrage/écartement relatif des demi-corps amont et aval par rapport à la plaque d’obturation, et l’organe d’indexage peut être solidarisé avec un tiroir agencé mobile selon au moins un degré de liberté en translation par rapport à la (ou aux) pièce(s) de guidage, le tiroir étant mobile entre une position de travail dans laquelle l’organe d’indexage est apte à indexer en position la plaque d’obturation par rapport au corps et une position de repos dans laquelle l’organe d’indexage n’est pas apte à indexer en position la plaque d’obturation par rapport au corps, le tiroir comportant au moins un crochet configuré pour, en position de travail, empêcher une manipulation des moyens de serrage/écartement et inversement, en position de repos, permettre une manipulation des moyens de serrage/écartement. Selon cette seconde variante de l’invention, l’organe d’indexage et le tiroir sont agencés en liaison de type encastrement et ne présentent aucun degré de liberté l’un par rapport à l’autre. Le tiroir et la (ou aux) pièce(s) de guidage peuvent quant à eux être agencés en liaison de type glissière et présentent l’un par rapport à l’autre un degré de liberté en translation dans un plan perpendiculaire par rapport au plan P. According to a second variant of the invention, the shutter may comprise clamping / spacing means making it possible to tighten, and conversely, to separate the upstream and downstream half-bodies relative to the closure plate to allow clamping / relative spacing of the upstream and downstream half-bodies with respect to the closure plate, and the indexing member can be secured with a drawer arranged movable according to at least one degree of freedom in translation relative to the (or) guide piece (s), the slide being movable between a working position in which the indexing member is capable of indexing in position the closure plate relative to the body and a rest position in which the d indexing is not suitable for indexing the closure plate in position relative to the body, the drawer comprising at least one hook configured to, in the working position, prevent manipulation of the clamping / spacing means and vice versa ent, in the rest position, allow manipulation of the clamping / spacing means. According to this second variant of the invention, the indexing member and the drawer are arranged in connection of the embedding type and have no degree of freedom with respect to one another. The drawer and the guide piece (s) can, for their part, be arranged in a slide-type connection and have, in relation to each other, a degree of freedom in translation in a plane perpendicular to the plane. P.
De plus selon cette seconde variante de l’invention, lorsque le tiroir est agencé dans la position de travail, les moyens de serrage/écartement ne peuvent être actionnés. En outre, l’organe d’indexage peut être avantageusement actionné au moyen d’une clé insérée dans une serrure ménagée dans le châssis de l’organe d’indexage. Dans ce cas, la présence de la clé dans la serrure permet alors d’agencer le doigt d’indexage dans la première position extrémale par rapport au châssis et l’absence de la clé dans la serrure permet alors d’agencer le doigt d’indexage dans la seconde position extrémale par rapport au châssis. In addition, according to this second variant of the invention, when the drawer is arranged in the working position, the clamping / spacing means cannot be actuated. In addition, the indexing member can be advantageously actuated by means of a key inserted in a lock provided in the chassis of the indexing member. In this case, the presence of the key in the lock then makes it possible to arrange the indexing finger in the first extreme position relative to the chassis and the absence of the key in the lock then makes it possible to arrange the finger indexing in the second extreme position relative to the chassis.
Par ailleurs, le(s) degré(s) de liberté de la liaison mécanique entre la plaque d’obturation et l’organe de suivi peu(ven)t être de différentes natures et correspondre à différents modes de réalisation de l’invention tels que décrits ci-dessous. Furthermore, the degree (s) of freedom of the mechanical connection between the closure plate and the monitoring member can be of different types and correspond to different embodiments of the invention such as described below.
Ainsi, selon un premier mode de réalisation de l’invention, le(s) degré(s) de liberté de la liaison mécanique peu(ven)t être un (ou des) degré(s) de liberté en translation. Thus, according to a first embodiment of the invention, the degree (s) of freedom of the mechanical connection can be (one or more) degree (s) of freedom in translation.
Dans ce premier mode de réalisation, la plaque d’obturation et l’organe de suivi peuvent se déplacer l’un par rapport à l’autre au moins en translation dans au moins une direction inscrite dans un plan perpendiculaire au plan P. Selon un deuxième mode de réalisation de l’invention, le(s) degré(s) de liberté de la liaison mécanique peu(ven)t être un (ou des) degré(s) de liberté en rotation. In this first embodiment, the closure plate and the tracking member can move relative to each other at least in translation in at least one direction inscribed in a plane perpendicular to the plane P. According to a second embodiment of the invention, the degree (s) of freedom of the mechanical connection can be a (or) degree (s) of freedom in rotation.
Dans ce second mode de réalisation, la plaque d’obturation et l’organe de suivi peuvent alors se déplacer l’un par rapport à l’autre au moins en rotation selon un axe de rotation orienté suivant une direction quelconque. In this second embodiment, the shutter plate and the tracking member can then move relative to each other at least in rotation along an axis of rotation oriented in any direction.
Selon un troisième mode de réalisation de l’invention, la plaque d’obturation peut coopérer avec l’organe de suivi selon une liaison mécanique de type ponctuelle présentant cinq degrés de liberté, deux degrés de liberté en translation et trois degrés de liberté en rotation. According to a third embodiment of the invention, the closure plate can cooperate with the monitoring member according to a mechanical connection of the point type having five degrees of freedom, two degrees of freedom in translation and three degrees of freedom in rotation.
Dans ce troisième mode de réalisation, la plaque d’obturation et l’organe de suivi peuvent alors se déplacer l’un par rapport à l’autre en translation dans deux directions perpendiculaires formant un plan perpendiculaire au plan P et en rotation selon trois axes de rotation orientés de façon perpendiculaire les uns par rapport aux autres. Ainsi, un premier axe de rotation peut être agencé parallèlement au plan P et les deux autres axes de rotation peuvent être inscrits dans un plan perpendiculaire au plan P. In this third embodiment, the closure plate and the tracking member can then move relative to each other in translation in two perpendicular directions forming a plane perpendicular to the plane P and rotating along three axes. of rotation oriented perpendicularly to each other. Thus, a first axis of rotation can be arranged parallel to the plane P and the other two axes of rotation can be inscribed in a plane perpendicular to the plane P.
Selon un quatrième mode de réalisation de l’invention, la plaque d’obturation peut coopérer avec l’organe de suivi selon une liaison élastique de type déformable présentant six degrés de liberté, trois degrés de liberté en translation et trois degrés de liberté en rotation. According to a fourth embodiment of the invention, the closure plate can cooperate with the monitoring member according to an elastic connection of the deformable type having six degrees of freedom, three degrees of freedom in translation and three degrees of freedom in rotation .
Selon un tel quatrième mode de réalisation, la plaque d’obturation et l’organe de suivi peuvent alors se déplacer l’un par rapport à l’autre en translation dans trois directions perpendiculaires et en rotation selon trois axes de rotation orientés de façon perpendiculaire les uns par rapport aux autres. Ces trois directions ou axes de rotation comportent ainsi une première direction ou premier axe de rotation agencé parallèlement au plan P et les deux autres directions ou axes de rotation peuvent être inscrits dans un plan perpendiculaire au plan P. L’invention et ses avantages apparaîtront avec plus de détails dans le cadre de la description qui suit avec des exemples donnés à titre illustratif en référence aux figures annexées qui représentent : - les figures 1 et 2, des vues en perspective d’un obturateur en ligne selon un premier exemple de réalisation conforme à l’invention, According to such a fourth embodiment, the closure plate and the tracking member can then move relative to each other in translation in three perpendicular directions and in rotation along three axes of rotation oriented perpendicularly. one to another. These three directions or axes of rotation thus comprise a first direction or first axis of rotation arranged parallel to the plane P and the other two directions or axes of rotation can be inscribed in a plane perpendicular to the plane P. The invention and its advantages will appear with more details in the context of the description which follows with examples given by way of illustration with reference to the appended figures which represent: FIGS. 1 and 2, perspective views of an in-line shutter according to a first embodiment example according to the invention,

- la figure 5, une vue de face d’un obturateur en ligne selon un second exemple de réalisation conforme à l’invention. - Figure 5, a front view of an in-line shutter according to a second embodiment according to the invention.
En outre, les éléments présents dans plusieurs figures distinctes peuvent être affectés d’une seule et même référence. In addition, the elements present in several separate figures can be assigned a single reference.
Comme déjà évoqué l’invention se rapporte à un obturateur en ligne permettant de réaliser une obturation étanche, et inversement, une circulation fluidique dans une canalisation entre une conduite amont agencée en amont de l’obturateur en ligne selon un sens de circulation fluidique et une conduite aval agencée en aval de l’obturateur en ligne selon le sens de circulation fluidique. As already mentioned, the invention relates to an in-line shutter making it possible to produce a sealed shutter, and conversely, a fluid circulation in a pipe between an upstream pipe arranged upstream of the inline shutter in a direction of fluid flow and a downstream pipe arranged downstream of the shutter in line in the direction of fluid flow.
Ainsi tel que représenté à la figure 1, l’obturateur en ligne 1 comporte une plaque d’obturation 2 mobile dans un plan P entre une position d’obturation arrêtant la circulation fluidique et une position de circulation permettant la circulation fluidique. Une telle plaque d’obturation 2 comporte alors une portion pleine 3 pour arrêter la circulation fluidique et une portion ajourée 4 pour permettre la circulation fluidique dans la canalisation. Par ailleurs, l’obturateur en ligne 1 comporte également un corps 5 formé par un demi-corps amont 6 et un demi-corps aval 7 agencés respectivement en amont et en aval de la plaque d’obturation 2. Ces demi-corps amont et aval 6 et 7 sont alors mobiles en translation l’un par rapport à l’autre perpendiculairement par rapport au plan P. De plus, ces demi- corps amont et aval 6 et 7 présentent respectivement un orifice amont 8 et un orifice aval 9 permettant de réaliser la circulation fluidique entre la conduite amont et la conduite aval. En outre, un tel obturateur en ligne 1 comporte également au moins un organe d’indexage 13, 13’ pour indexer en position la plaque d’obturation 2 par rapport au corps 5 dans la position d’obturation et alternativement pour indexer en position la plaque d’obturation 2 par rapport au corps 5 dans la position de circulation. Thus, as shown in FIG. 1, the in-line shutter 1 comprises a shutter plate 2 movable in a plane P between a shutter position stopping the fluid circulation and a circulation position allowing the fluid circulation. Such a closure plate 2 then comprises a solid portion 3 to stop the fluid circulation and an openwork portion 4 to allow the fluid circulation in the pipeline. Furthermore, the in-line shutter 1 also comprises a body 5 formed by an upstream half-body 6 and a downstream half-body 7 arranged respectively upstream and downstream of the closure plate 2. These upstream half-body and downstream 6 and 7 are then movable in translation relative to each other perpendicular to the plane P. In addition, these upstream and downstream half-bodies 6 and 7 respectively have an upstream orifice 8 and a downstream orifice 9 making it possible to carry out the fluid circulation between the upstream pipe and the downstream pipe. In addition, such an in-line shutter 1 also comprises at least one indexing member 13, 13 'for indexing in position the shutter plate 2 relative to the body 5 in the shutter position and alternatively for indexing in position the closure plate 2 with respect to the body 5 in the circulation position.
Un tel organe d’indexage 13, 13’ comporte alors un châssis 14, 14’ et au moins un doigt d’indexage 15, 15’ mobile entre deux positions extrémales par rapport au châssis 14, 14’. Une première position extrémale du doigt d’indexage 15, 15’ correspond à une position déployée dans laquelle l’organe d’indexage 13, 13’ indexe en position la plaque d’obturation 2 par rapport au corps 5. Une seconde position extrémale du doigt d’indexage 15, 15’ correspond à une position rétractée dans laquelle l’organe d’indexage 13, 13’ donne une liberté de mouvement à la plaque d’obturation 2 par rapport au corps 5. Such an indexing member 13, 13 'then comprises a chassis 14, 14' and at least one indexing finger 15, 15 'movable between two extreme positions relative to the chassis 14, 14'. A first extreme position of the indexing finger 15, 15 ′ corresponds to a deployed position in which the indexing member 13, 13 ′ indexes the closure plate 2 in position relative to the body 5. A second extreme position of the indexing finger 15, 15 'corresponds to a retracted position in which the indexing member 13, 13' gives freedom of movement to the closure plate 2 relative to the body 5.
Au surplus, l’obturateur en ligne 1 comporte également un organe de suivi 16 déporté latéralement par rapport à la plaque d’obturation 2. Un tel organe de suivi 16 est ainsi configuré pour suivre les déplacements de la plaque d’obturation 2 mobile dans le plan P entre la position d’obturation et la position de circulation. De plus, l’organe de suivi 16 comporte au moins deux alésages 17, 18 aptes à coopérer respectivement avec le doigt d’indexage 15, 15’ agencé dans la première position extrémale par rapport au châssis 14, 14’. Ainsi, un premier alésage 17 peut coopérer avec le doigt d’indexage 15 d’un premier organe d’indexage 13 lorsque la plaque d’obturation 2 est positionnée dans la position d’obturation et alternativement un deuxième alésage 18 peut coopérer avec le doigt d’indexage 15’ d’un second organe d’indexage 13’ lorsque la plaque d’obturation 2 est positionnée dans la position de circulation. In addition, the in-line shutter 1 also includes a tracking member 16 offset laterally relative to the shutter plate 2. Such a tracking member 16 is thus configured to follow the movements of the shutter plate 2 movable in the plane P between the closed position and the circulation position. In addition, the monitoring member 16 comprises at least two bores 17, 18 able to cooperate respectively with the indexing finger 15, 15 'arranged in the first extreme position relative to the chassis 14, 14'. Thus, a first bore 17 can cooperate with the indexing finger 15 of a first indexing member 13 when the closure plate 2 is positioned in the closure position and alternatively a second bore 18 can cooperate with the finger indexing 15 'of a second indexing member 13' when the closure plate 2 is positioned in the circulation position.
En outre tel que représenté à la figure 1, l’obturateur en ligne 1 comporte également des moyens de guidage 20 configurés pour guider indépendamment des mouvements de l’organe de suivi 16 par rapport au corps 5 lors des déplacements relatifs de la plaque d’obturation 2 par rapport au corps 5. In addition as shown in FIG. 1, the in-line shutter 1 also includes guide means 20 configured to independently guide the movements of the tracking member 16 relative to the body 5 during the relative movements of the plate. obturation 2 relative to the body 5.
De plus, la plaque d’obturation 2 peut coopérer avec l’organe de suivi 16 selon une liaison mécanique de type présentant au moins un degré de liberté telle que par exemple une liaison de type appui-plan présentant deux degrés de liberté en translation dans un plan P’ perpendiculaire au plan P et un degré de liberté en rotation autour d’un axe de rotation Oz perpendiculaire au plan P’. In addition, the shutter plate 2 can cooperate with the monitoring member 16 according to a mechanical connection of the type having at least one degree of freedom such as for example a connection of the flat support type having two degrees of freedom in translation in a plane P 'perpendicular to the plane P and a degree of freedom in rotation about an axis of rotation Oz perpendicular to the plane P'.
Tels que représentés aux figures 1 à 4 correspondant à un premier exemple de réalisation de l’invention, de tels moyens de guidage 20 sont configurés pour guider en translation suivant l’axe Oz les mouvements de l’organe de suivi 16 par rapport au corps 5. As shown in Figures 1 to 4 corresponding to a first embodiment of the invention, such guide means 20 are configured to guide in translation along the axis Oz the movements of the tracking member 16 relative to the body 5.
Par ailleurs, les moyens de guidage 20 comportent au moins une pièce de guidage 23 solidarisée avec le corps 5. Une telle pièce de guidage 23 présente ainsi un orifice 24 au travers duquel l’organe de suivi 16 peut se déplacer avec un jeu de guidage adapté. Dans ce cas, l’obturateur en ligne 1 peut alors comporter deux organes d’indexage 13, 13’ solidarisés avec la pièce de guidage 23. L’utilisation de deux organes d’indexage 13, 13’ peut en effet être avantageuse pour permettre "d’inter-verrouiller" l’indexage en position de la plaque d’obturation 2 avec des moyens de serrage/écartement 48 permettant de serrer, et inversement, d’écarter les demi-corps amont et aval 6 et 7 par rapport à la plaque d’obturation 2 pour permettre un serrage/écartement relatif des demi-corps amont et aval 6 et 7 par rapport à la plaque d’obturation 2. Furthermore, the guide means 20 comprise at least one guide piece 23 secured to the body 5. Such a guide piece 23 thus has an orifice 24 through which the tracking member 16 can move with a guide clearance adapted. In this case, the in-line shutter 1 can then comprise two indexing members 13, 13 ′ secured to the guide piece 23. The use of two indexing members 13, 13 ′ may indeed be advantageous to allow "inter-locking" the indexing in position of the closure plate 2 with clamping / spacing means 48 making it possible to clamp , and conversely, to separate the upstream and downstream half-bodies 6 and 7 relative to the closure plate 2 to allow a relative tightening / spacing of the upstream and downstream half-bodies 6 and 7 relative to the plate shutter 2.
Un tel inter-verrouillage garantit ainsi un verrouillage en position des moyens de serrage/écartement 48 tant que la plaque d’obturation 2 n’est pas agencée dans la position d’obturation ou alternativement dans la position de circulation. Such interlocking thus guarantees locking in position of the clamping / spacing means 48 as long as the shutter plate 2 is not arranged in the shutter position or alternatively in the circulation position.
Par les termes "clé" et "serrure" utilisés pour décrire de tels moyens d’inter-verrouillage, on entend tout type de clé présentant un code d’identification personnel telle une pièce mécanique rigide comportant par exemple à une extrémité des dents, des formes ou des encoches pour actionner un pêne complémentaire. Cependant, l’invention ne se limite pas à cet unique mode de réalisation, les termes "clé" et "serrure" pouvant également désigner une carte ou un support intégrant des organes magnétiques, électroniques ou électromagnétiques de stockage d’un code d’identification. Dans ce cas, les serrures complémentaires peuvent comporter respectivement chacune un dispositif de lecture magnétique, électronique ou électromagnétique pour lire les informations stockées dans les clés distinctes l’une de l’autre. By the terms "key" and "lock" used to describe such interlocking means is meant any type of key having a personal identification code such as a rigid mechanical part comprising, for example at one end of the teeth, shapes or notches to activate a complementary bolt. However, the invention is not limited to this single embodiment, the terms "key" and "lock" can also denote a card or a support incorporating magnetic, electronic or electromagnetic organs for storing an identification code . In this case, the complementary locks may each comprise a magnetic, electronic or electromagnetic reading device, respectively, for reading the information stored in the keys which are separate from one another.
Tel que représenté, l’obturateur en ligne 1 peut alors être équipé de moyens d’inter-verrouillage permettant d’imposer à un opérateur une séquence d’obturation pour réaliser l’obturation étanche de la (ou des) canalisation(s) et une séquence inverse pour réaliser l’ouverture de la (ou des) canalisation(s). De tels moyens d’inter-verrouillage comportent alors au moins deux clés 41 et 47 distinctes l’une de l’autre et au moins deux jeux de deux serrures 42, 43 et 45, 46 complémentaires. As shown, the in-line shutter 1 can then be equipped with interlocking means making it possible to impose on an operator a shutter sequence to achieve the tight shutter of the pipe (s) and reverse sequence to open the pipe (s). Such interlocking means then comprise at least two keys 41 and 47 distinct from each other and at least two sets of two locks 42, 43 and 45, 46 complementary.
En outre, l’insertion d’une clé supplémentaire 50 dans le premier organe d’indexage 13 permet à la fois de rétracter le doigt d’indexage 15 à l’intérieur du châssis 14 et de libérer la clé 41 de la serrure 42 d’un organe d’inter-verrouillage 40. Un opérateur peut extraire la clé 41 de la serrure 42 et placer alors la clé 41 dans la serrure 43 agencée au niveau des moyens de serrage/écartement 48. De cette manière, les moyens de serrage/écartement 48 comportent les deux clés 41 et 47 insérées respectivement dans les serrures 43 et 46 et un volant 49 peut être manœuvré par l’opérateur pour écarter relativement l’un de l’autre les demi-corps amont et aval 6 et 7. In addition, the insertion of an additional key 50 into the first indexing member 13 makes it possible both to retract the indexing finger 15 inside the chassis 14 and to release the key 41 from the lock 42 d an interlocking member 40. An operator can extract the key 41 from the lock 42 and then place the key 41 in the lock 43 arranged at the clamping / spacing means 48. In this way, the clamping means / spacing 48 comprise the two keys 41 and 47 inserted respectively in the locks 43 and 46 and a steering wheel 49 can be operated by the operator to move the upstream and downstream half-bodies 6 and 7 relatively apart from one another.
Tel que représenté à la figure 2, une fois l’écartement des demi-corps amont et aval 6 et 7 réalisé, l’opérateur peut alors saisir la clé 47 présente dans la serrure 46 et placer cette clé 47 dans la serrure 45 d’un autre organe d’inter-verrouillage 44. L’insertion de cette clé 47 dans la serrure 45 a alors pour effet de rétracter un doigt d’indexage 15" à l’intérieur d’un châssis 14" de l’organe d’inter-verrouillage 44. As shown in FIG. 2, once the separation of the upstream and downstream half-bodies 6 and 7 has been achieved, the operator can then grasp the key 47 present in the lock 46 and place this key 47 in the lock 45 d ' another interlocking member 44. The insertion of this key 47 into the lock 45 then has the effect of retracting an indexing finger 15 "inside a chassis 14" of the interlock 44.
De cette manière, l’opérateur fait sortir le doigt d’indexage 15" d’un alésage 29 ménagé dans l’organe de suivi 16 et libère ainsi l’organe de suivi 16 qui peut alors être déplacé par rapport à la pièce de guidage 23. L’opérateur peut alors déplacer la plaque d’obturation 2 mobile dans le plan P entre la position de circulation et la position d’obturation. In this way, the operator brings out the indexing finger 15 "from a bore 29 formed in the tracking member 16 and thus frees the tracking member 16 which can then be moved relative to the guide piece. 23. The operator can then move the movable closure plate 2 in the plane P between the circulation position and the closure position.
Une fois le déplacement de la plaque d’obturation 2 réalisé, l’opérateur peut alors saisir à nouveau la clé 47 présente dans la serrure 45 de l’organe d’inter-verrouillage 44 et replacer cette clé 47 dans la serrure 46 des moyens de serrage/écartement 48. Le retrait de la clé 47 de la serrure 45 provoque la sortie du doigt d’indexage 15" vers l’extérieur du châssis 14" et vient coopérer avec un alésage 19 ménagé dans l’organe de suivi 16. Par ailleurs, l’insertion de cette clé 47 dans la serrure 46 a alors pour effet de libérer les moyens de serrage/écartement 48. Once the closure plate 2 has been moved, the operator can then re-enter the key 47 present in the lock 45 of the interlocking member 44 and replace this key 47 in the lock 46 of the means tightening / spacing 48. The withdrawal of the key 47 from the lock 45 causes the indexing finger 15 "to exit towards the outside of the chassis 14" and comes to cooperate with a bore 19 made in the monitoring member 16. Furthermore, the insertion of this key 47 in the lock 46 then has the effect of releasing the clamping / spacing means 48.
Ensuite, l’opérateur manœuvre le volant 49 en sens inverse pour serrer à nouveau les demi-corps amont et aval 6 et 7 contre la plaque 2. Then, the operator operates the flywheel 49 in the opposite direction to tighten the upstream and downstream half-bodies 6 and 7 again against the plate 2.
L’opérateur peut saisir la clé 41 présente dans la serrure 43 et placer cette clé 41 dans la serrure 42 de l’organe d’inter- verrouillage 40. L’insertion de cette clé 41 dans la serrure 42 a alors pour effet de libérer une clé 51 du second organe d’indexage 13’. The operator can grasp the key 41 present in the lock 43 and place this key 41 in the lock 42 of the interlocking member 40. The insertion of this key 41 in the lock 42 then has the effect of releasing a key 51 of the second indexing member 13 '.
L’opérateur peur alors saisir la clé 51 et l’extraire de second organe d’indexage 13’ ce qui a pour effet de déployer le doigt d’indexage 15’ à l’intérieur du deuxième alésage 18 agencé en regard. The operator can then enter the key 51 and extract it from the second indexing member 13 ’, which has the effect of deploying the indexing finger 15’ inside the second bore 18 arranged opposite.
En outre, en fonction de la clé 50 ou 51 libre et non connectée avec le premier ou le second organe d’indexage 13 ou 13’ un opérateur peut connaître l’état de fermeture ou d’ouverture d’un tel obturateur en ligne 1 et donc la position de la plaque d’obturation 2 par rapport au corps 5. In addition, depending on the key 50 or 51 free and not connected with the first or second indexing member 13 or 13 'an operator can know the state of closing or opening of such a shutter in line 1 and therefore the position of the closure plate 2 relative to the body 5.
Par ailleurs tel que représenté à la figure 3, un autre type d’obturateur en ligne 11 peut quant à lui comporter un autre type de moyens de serrage/écartement 10 permettant de serrer, et inversement, d’écarter les demi-corps amont et aval 6 et 7 par rapport à une plaque d’obturation 12 pour permettre un serrage/écartement relatif des demi-corps amont et aval 6 et 7 par rapport à la plaque d’obturation 12. Par ailleurs dans ce cas, deux organes d’indexage 13, 13’ peuvent être solidarisés avec un tiroir 35 agencé mobile selon au moins un degré de liberté en translation par rapport à une pièce de guidage 33 des moyens de guidage 30 solidarisée avec le corps 5. En outre, ce tiroir 35 est agencé mobile entre une position de travail dans laquelle les organes d’indexage 13, 13’ sont aptes à indexer en position la plaque d’obturation 12 par rapport au corps 5 et une position de repos dans laquelle les organes d’indexage 13, 13’ ne peuvent pas indexer en position la plaque d’obturation 12 par rapport au corps 5. Furthermore, as shown in FIG. 3, another type of in-line shutter 11 may in turn include another type of clamping / spacing means 10 making it possible to tighten, and conversely, to separate the upstream half-bodies and downstream 6 and 7 relative to a closure plate 12 to allow relative tightening / spacing of the upstream and downstream half-bodies 6 and 7 relative to the closure plate 12. Furthermore, in this case, two indexing members 13, 13 ′ can be secured to a slide 35 arranged movable according to at least one degree of freedom in translation relative to a guide piece 33 of the guide means 30 secured to the body 5. In addition, this drawer 35 is arranged movable between a working position in which the indexing members 13, 13 'are capable of indexing in position the closure plate 12 relative to the body 5 and a rest position in which the indexing members 13, 13 ′ cannot index the closure plate 12 relative to the body 5 in position.
De plus, le tiroir 35 comporte au moins un crochet 36 configuré pour, en position de travail, empêcher une manipulation des moyens de serrage/écartement 10 en coopérant avec un levier 37 et inversement, en position de repos, permettre une manipulation des moyens de serrage/écartement 10 en libérant le levier 37. In addition, the drawer 35 has at least one hook 36 configured to, in the working position, prevent manipulation of the clamping / spacing means 10 by cooperating with a lever 37 and conversely, in the rest position, allow manipulation of the tightening / spacing 10 by releasing the lever 37.
Dans ce cas, la plaque d’obturation 12 peut coopérer avec l’organe de suivi 16 avec des vis de pression 38 et 39 permettant de réaliser une liaison mécanique de type ponctuelle présentant cinq degrés de liberté, deux degrés de liberté en translation dans le plan P’ et trois degrés de liberté en rotation suivant trois axes perpendiculaires entre eux, deux axes Ox , Oy étant inscrits dans le plan P’ et un axe Oz étant perpendiculaire au plan P’. In this case, the closure plate 12 can cooperate with the monitoring member 16 with pressure screws 38 and 39 allowing a point-type mechanical connection having five degrees of freedom, two degrees of freedom in translation in the plane P 'and three degrees of freedom in rotation along three axes perpendicular to each other, two axes Ox, Oy being inscribed in the plane P' and an axis Oz being perpendicular to the plane P '.
En outre à la figure 3, la plaque d’obturation 12 de l’obturateur en ligne 11 est représentée dans une position de circulation permettant la circulation fluidique. Dans ce cas, la clé 51 est extraite d’une serrure 53 et permet au doigt d’indexage 15’ d’être agencé dans une première position extrémale en coopérant avec un premier alésage 17 de l’organe de suivi 16. Telle que représentée à la figure 4, la plaque d’obturation 12 de l’obturateur en ligne 11 est agencée dans une position d’obturation arrêtant la circulation fluidique. Dans ce cas, la clé 50 est extraite d’une serrure 52 et permet au doigt d’indexage 15 d’être agencé dans une première position extrémale en coopérant avec un second alésage 18 de l’organe de suivi 16. In addition, in FIG. 3, the closure plate 12 of the in-line shutter 11 is shown in a circulation position allowing fluid circulation. In this case, the key 51 is extracted from a lock 53 and allows the indexing finger 15 ′ to be arranged in a first extreme position by cooperating with a first bore 17 of the tracking member 16. As shown in Figure 4, the shutter plate 12 of the in-line shutter 11 is arranged in a shutter position stopping the fluid circulation. In this case, the key 50 is extracted from a lock 52 and allows the indexing finger 15 to be arranged in a first extreme position by cooperating with a second bore 18 of the tracking member 16.
De même que précédemment à la figure 1, en fonction de la clé 50 ou 51 libre et non connectée avec le premier ou second organe d’indexage 13 ou 13’ un opérateur peut connaître de façon certaine et à distance l’état de fermeture ou d’ouverture d’un tel obturateur en ligne 11. As previously in FIG. 1, as a function of the key 50 or 51 which is free and not connected with the first or second indexing member 13 or 13 ′, an operator can know in a certain and remote manner the closed state or opening such a shutter in line 11.
Par ailleurs, une fois l’introduction de l’une des clés 50 ou 51 dans l’une des serrures 52 ou 53 réalisée, l’opérateur peut alors exercer un effort sur la clé considérée 50 ou 51, cet effort étant orienté suivant la direction d’introduction de la clé 50 ou 51. Furthermore, once the introduction of one of the keys 50 or 51 into one of the locks 52 or 53 has been carried out, the operator can then exert a force on the key considered 50 or 51, this force being oriented according to the direction of insertion of the key 50 or 51.
Un tel effort exercé par l’opérateur peut alors provoquer instantanément le déplacement du tiroir 35 par rapport à une pièce de guidage 33 et permet de positionner le tiroir 35 en position de repos. Such an effort exerted by the operator can then instantly cause the drawer 35 to move relative to a guide piece 33 and makes it possible to position the drawer 35 in the rest position.
En outre tels que représentés à la figure 5 correspondant à un second exemple de réalisation de l’invention, l’obturateur en ligne 21 peut comporter des moyens de guidage 30 configurés pour guider en rotation suivant un axe Oz’ les mouvements de l’organe de suivi 26 par rapport au corps 25. Dans ce cas, la plaque d’obturation 22 est également mobile en rotation par rapport au corps 25. In addition as shown in FIG. 5 corresponding to a second embodiment of the invention, the in-line shutter 21 may include guide means 30 configured to guide in rotation along an axis Oz ′ the movements of the member. tracking 26 relative to the body 25. In this case, the closure plate 22 is also movable in rotation relative to the body 25.
De plus, la plaque d’obturation 22 peut quant à elle coopérer avec l’organe de suivi 26 selon une liaison élastique de type déformable présentant six degrés de liberté, trois degrés de liberté en translation suivant des axes Ox\ Oy’ et Oz’ et trois degrés de liberté en rotation suivant les axes Ox\ Oy’ et Oz’. In addition, the closure plate 22 can in turn cooperate with the tracking member 26 according to an elastic connection of the deformable type having six degrees of freedom, three degrees of freedom. in translation along the axes Ox \ Oy 'and Oz' and three degrees of freedom in rotation along the axes Ox \ Oy 'and Oz'.
Une telle liaison élastique peut par exemple être réalisée au moyen d’un organe déformable 27 agencé à au moins une extrémité de l’organe de suivi 26. Un tel organe déformable 27 peut par exemple être formé en tout ou partie dans un matériau polymère élastique comportant des capacités de déformation en translation et en rotation suivant les trois axes Ox\ Oy’ et Oz’. Such an elastic connection may for example be produced by means of a deformable member 27 arranged at at least one end of the tracking member 26. Such a deformable member 27 may for example be formed wholly or partly in an elastic polymer material with deformation capacities in translation and in rotation along the three axes Ox \ Oy 'and Oz'.
Naturellement, la présente invention est sujette à de nombreuses variations quant à sa mise en œuvre. Bien que plusieurs modes de réalisation aient été décrits, on comprend bien qu’il n’est pas concevable d’identifier de manière exhaustive tous les modes possibles. Il est bien sûr envisageable de remplacer un moyen décrit par un moyen équivalent sans sortir du cadre de la présente invention. Naturally, the present invention is subject to numerous variations as to its implementation. Although several embodiments have been described, it is understood that it is not conceivable to identify exhaustively all the possible modes. It is of course conceivable to replace a means described by an equivalent means without departing from the scope of the present invention.
