Description
La présente invention se rapporte à un dispositif d'ouverture/fermeture intégrale et rapide de tubulure de réacteur, également connue sous la dénomination de trou d'homme.The present invention relates to a device for opening / closing integral and fast reactor tubing, also known as the manhole.
L'invention concerne plus particulièrement un dispositif d'ouverture/fermeture intégrale et rapide de trou d'homme de réacteur émaillé comportant des systèmes de manivelles à came.The invention more particularly relates to an integral and rapid opening / closing device enamelled reactor manhole having cam crank systems.
Une tubulure de réacteur de type trou d'homme est un piquage réalisé sur un réacteur chimique permettant à une personne de pénétrer dans le réacteur, notamment en vue de son nettoyage, de son contrôle, de sa maintenance ou de son remplissage avec des produits chimiques.A manhole type reactor manifold is a stitching made on a chemical reactor allowing a person to enter the reactor, in particular for cleaning, checking, maintenance or filling with chemicals. .
Un tel piquage est bordé par une bride sur laquelle vient se monter un tampon permettant de fermer le trou d'homme du réacteur.Such stitching is bordered by a flange on which is mounted a buffer for closing the manhole of the reactor.
Habituellement le tampon est maintenu en place sur la bride du piquage par un système de crampons mis en place et répartis sur le pourtour de la bride, ces crampons venant enserrer le rebord du tampon et celui de la bride. Le serrage de l'écrou de chaque crampon permet de plaquer fermement le tampon sur la bride du piquage. Cette étape de serrage est très longue et fastidieuse, car chaque crampon doit être serré, tout en veillant à ce que la force de serrage soit appliqué de manière uniforme et que chaque crampon soit serré de manière sensiblement équivalente.Usually the buffer is held in place on the flange of the stitching by a system of studs placed and distributed around the perimeter of the flange, these studs coming to grip the edge of the pad and that of the flange. Tightening the nut of each clamp makes it possible to firmly press the pad onto the flange of the stitching. This clamping step is very long and tedious, because each clamp has to be tightened, while ensuring that the clamping force is uniformly applied and that each clamp is tightened in a substantially equivalent manner.
Lors de l'ouverture du trou d'homme du réacteur, il faut effectuer l'opération inverse, à savoir desserrer tous les crampons et les retirer du pourtour de la bride.When opening the manhole of the reactor, perform the opposite operation, ie loosen all the crampons and remove them from around the flange.
Le tampon étant monté à articulation sur le réacteur par l'intermédiaire d'une charnière ou d'une potence, il n'est pas nécessaire de le retirer entièrement, il suffit de le basculer en ouverture sur le côté.The buffer being hingedly mounted on the reactor by means of a hinge or a bracket, it is not necessary to remove it entirely, it is sufficient to tilt it in opening on the side.
On comprendra bien que le système de crampons, s'il est relativement efficace et peu coûteux, ne permet pas d'ouverture ou de fermeture rapide d'un trou d'homme.It will be understood that the spike system, while relatively efficient and inexpensive, does not allow rapid opening or closing of a manhole.
En outre, lorsque le réacteur a subit des vibrations et/ou des changements de température, il peut arriver que les crampons se grippent, ce qui complique encore la tâche déjà très longue de desserrage des tous les crampons.In addition, when the reactor is subjected to vibrations and / or changes in temperature, it may happen that the crampons seize, which further complicates the already very long task of loosening all the crampons.
D'autres solutions ont donc été développées pour l'ouverture et la fermeture des trous d'homme de réacteur.Other solutions have therefore been developed for opening and closing the reactor manholes.
Parmi les systèmes développés, on connaît notamment des dispositifs à manivelle centrale qui, par l'intermédiaire d'un système de tringlerie, permet d'actionner simultanément plusieurs moyens de verrouillage en ouverture ou en fermeture.Among the systems developed, there are known including central crank devices which, via a linkage system, allows to operate simultaneously several locking means opening or closing.
En plus d'être encombrants et fragiles, bien qu'ils permettent habituellement de verrouiller et déverrouiller un trou d'homme rapidement, ces dispositifs ne sont pas satisfaisants pour de nombreuses raisons.In addition to being bulky and fragile, although they usually allow you to lock and unlock a manhole quickly, these devices are unsatisfactory for many reasons.
Lorsque le système de tringlerie et/ou les moyens de verrouillage sont situés sous le tampon refermant le trou d'homme, ils sont soumis aux vapeurs et éclaboussure des produits chimiques, souvent corrosifs, contenus dans le réacteur. Il en résulte une détérioration rapide du dispositif d'ouverture/fermeture.When the linkage system and / or the locking means are located under the buffer closing the manhole, they are subjected to vapors and splashing chemicals, often corrosive, contained in the reactor. This results in a rapid deterioration of the opening / closing device.
Ces dispositifs comportent généralement des pièces qui sont solidarisées sur le réacteur et/ou sur son tampon. Aussi, leur maintenance et leur remplacement sont complexes et coûteux, et nécessitent parfois de remplacer tout ou partie du réacteur et/ou de son tampon.These devices generally comprise parts which are secured to the reactor and / or its buffer. Also, their maintenance and replacement are complex and expensive, and sometimes require replacing all or part of the reactor and / or its buffer.
De même, ces dispositifs ne peuvent habituellement pas être adaptés à tous les types de réacteurs actuels et anciens.Similarly, these devices can not usually be adapted to all types of current and old reactors.
Ils n'exercent pas toujours un effort suffisant pour assurer l'étanchéité entre le tampon et la bride du trou d'homme, notamment en cas de température et/ou de pression élevée dans le réacteur.They do not always exert sufficient force to ensure the seal between the buffer and the flange of the manhole, especially in case of temperature and / or high pressure in the reactor.
Dans le cas des réacteurs émaillés, il arrive fréquemment que la planéité de la bride du trou d'homme soit légèrement déformée lors du chauffage intense effectué lors de l'émaillage du réacteur. Les dispositifs d'ouverture/fermeture de trou d'homme existants ne permettent généralement pas de tenir compte de cette légère déformation et ne garantissent pas une étanchéité satisfaisante en fermeture.In the case of enamelled reactors, it frequently happens that the flatness of the flange of the manhole is slightly deformed during the intense heating carried out during the enameling of the reactor. Existing opening / closing devices manhole generally do not allow to take into account this slight deformation and do not guarantee a satisfactory seal closure.
Enfin, ces dispositifs ne permettent pas toujours une ouverture et une fermeture rapides, nécessitent parfois un grand effort physique et/ou des outils pour leurs manipulation, ne sont pas toujours compatibles avec les charnières ou potences permettant de déplacer le tampon, ni avec les piquages susceptibles d'être prévus sur le tampon.Finally, these devices do not always allow rapid opening and closing, sometimes require great physical effort and / or tools for handling, are not always compatible with the hinges or brackets to move the buffer, or with the taps likely to be provided on the buffer.

Les éléments structurellement et fonctionnellement identiques présents sur plusieurs figures distinctes, sont affectés d'une même référence numérique ou alphanumérique.The structurally and functionally identical elements present in several separate figures are assigned a same numerical or alphanumeric reference.
Le dispositif d'ouverture/fermeture (1) rapide de l'invention est prévu pour équiper une tubulure ou un piquage (2) présentant une ouverture (3) bordée par une bride (4) ou un rebord et fermée par un tampon (5). Bien que l'invention ne se limite pas à cette application, le dispositif d'ouverture/fermeture (1) rapide de l'invention sera décrit dans le cas où il équipe le trou d'homme (2, 6) d'un réacteur chimique (7) émaillé. Ainsi, bien que l'invention puisse s'adapter à n'importe quel(le) tubulure ou piquage (2), elle sera décrite ici dans le cas où le piquage (2) est un trou d'homme (2, 6). The rapid opening / closing device (1) of the invention is adapted to equip a tubing or stitching (2) having an opening (3) bordered by a flange (4) or a flange and closed by a buffer (5). ). Although the invention is not limited to this application, the rapid opening / closing device (1) of the invention will be described in the case where it equips the manhole (2, 6) of a reactor chemical (7) enamelled. Thus, although the invention can be adapted to any (the) tubing or stitching (2), it will be described here in the case where the stitching (2) is a manhole (2, 6) .
L'ouverture (3) d'un tel trou d'homme (2, 6) est habituellement fermée par un tampon (5) monté à articulation sur le réacteur (7) par l'intermédiaire d'un dispositif de basculement (8) à charnière ou à potence qui peut être actionné ou assisté par un vérin (9). Ce tampon (5) peut lui-même présenter un ou plusieurs piquages (2b), et une poignée (10) pour sa manipulation en ouverture et en fermeture.The opening (3) of such a manhole (2, 6) is usually closed by a buffer (5) pivotally mounted on the reactor (7) via a tilting device (8) hinge or stem which can be actuated or assisted by a jack (9). This buffer (5) can itself have one or more taps (2b), and a handle (10) for its manipulation in opening and closing.
Le dispositif d'ouverture/fermeture (1) rapide de l'invention comprend une bride intermédiaire (11) prévue pour être montée entre la bride (4) du trou d'homme (2, 6) et le tampon (5). Cette bride intermédiaire (11) n'est pas systématiquement émaillée et est préférentiellement fabriquée avec une base en acier noir ou inoxydable et d'un surmoulage de type TFM, PFA ou PTFE pour la zone en contact avec le ciel réactionnel.The quick opening / closing device (1) of the invention comprises an intermediate flange (11) adapted to be mounted between the flange (4) of the manhole (2, 6) and the pad (5). This intermediate flange (11) is not systematically enamelled and is preferably manufactured with a black or stainless steel base and overmoulding type TFM, PFA or PTFE for the zone in contact with the reaction sky.
La bride intermédiaire (11) est solidarisée sur la bride (4) du trou d'homme (2, 6), par exemple au moyen de crampons (12) munis chacun d'un écrou (13) et répartis sur le pourtour de la bride intermédiaire (11). Par le serrage de l'écrou (13) de chaque crampon (12), ces crampons (12) viennent serrer la face supérieure de la bride (4) du trou d'homme (2, 6) contre la face inférieure de la bride intermédiaire (11). The intermediate flange (11) is secured to the flange (4) of the manhole (2, 6), for example by means of crampons (12) each provided with a nut (13) and distributed around the periphery of the intermediate flange (11). By tightening the nut (13) of each crampon (12), these crampons (12) tighten the upper face of the flange (4) of the manhole (2, 6) against the underside of the flange. intermediate (11).
Les crampons (12) peuvent être d'une seule pièce avec la bride intermédiaire (11), ou vissés sous sur celle-ci.The crampons (12) can be in one piece with the flange intermediate (11), or screwed under on it.
Les crampons (12) sont préférentiellement prévus de sorte de laisser libre la face supérieure de la bride intermédiaire (11). The crampons (12) are preferably provided so as to leave the upper face of the intermediate flange (11) free.
Le serrage l'écrou (13) de chaque crampon (12) permet de plaquer fermement la bride intermédiaire (11) sur la bride (4) du trou d'homme (2, 6). Cette opération n'est effectuée qu'une fois lors de la mise en place du dispositif d'ouverture/fermeture (1) rapide de l'invention sur un trou d'homme (2, 6). Ces écrous (13) n'auront pas à être manipulés lors des phases ultérieures d'ouverture ou de fermeture du trou d'homme (2, 6). Tightening the nut (13) of each crampon (12) makes it possible to firmly press the intermediate flange (11) onto the flange (4) of the manhole (2, 6). This operation is performed only once during the introduction of the quick opening / closing device (1) of the invention on a manhole (2, 6). These nuts (13) will not have to be handled during the subsequent phases of opening or closing the manhole (2, 6).
Cette bride intermédiaire (11) permet d'adapter l'ensemble du dispositif d'ouverture/fermeture (1) rapide de l'invention sur n'importe quel trou d'homme (2, 6) existant. Elle sert en effet de support pour tous les éléments constitutifs du dispositif (1) de l'invention, y compris le tampon (5) et son dispositif de basculement (8). Une fois cette bride intermédiaire (11) solidarisée sur le trou d'homme (2, 6), il n'est pas nécessaire qu'un autre élément constitutif du dispositif (1) de l'invention soit solidarisé au réacteur (7). This intermediate flange (11) makes it possible to adapt the assembly of the quick opening / closing device (1) of the invention to any existing manhole (2, 6) . It serves in effect support for all the constituent elements of the device (1) of the invention, including the buffer (5) and its tilting device (8). Once this intermediate flange (11) secured to the manhole (2, 6), it is not necessary that another component of the device (1) of the invention is secured to the reactor (7).
La bride intermédiaire (11) permet également de compenser un éventuel défaut de planéité de la bride (4) du trou d'homme (2, 6), afin d'offrir par sa face supérieure, une surface plane sans défaut sur laquelle peut reposer le tampon (5) pour une parfaite étanchéité.The intermediate flange (11) also makes it possible to compensate for any lack of flatness of the flange (4) of the manhole (2, 6), in order to provide on its upper face a flawless flat surface on which can rest the buffer (5) for a perfect seal.
L'étanchéité entre la bride intermédiaire (11) et la bride (4) du trou d'homme (2, 6) est améliorée par la fourniture d'une première garniture d'étanchéité (14) prévue entre ces deux pièces (11, 4). Cette première garniture d'étanchéité (14) comprend préférentiellement un joint plat (15) prévu sur la zone de contact située entre la face supérieure de la bride (4) du trou d'homme (2, 6) et la face inférieure de la bride intermédiaire (11). The seal between the intermediate flange (11) and the flange (4) of the manhole (2, 6) is improved by the provision of a first seal (14) provided between these two parts (11, 4). This first seal (14) preferably comprises a flat seal (15) provided on the contact zone situated between the upper face of the flange (4) of the manhole (2, 6) and the lower face of the intermediate flange (11).
Une seconde garniture d'étanchéité (16) est également prévue entre la face supérieure de la bride intermédiaire (11) et la face inférieure du tampon (5). Cette seconde garniture d'étanchéité (16) peut comporter une bague d'étanchéité (17) montée sur l'ouverture de la bride intermédiaire (11), comportant un méplat horizontal (18) en appui sur la face supérieure de la bride intermédiaire (11). Un joint torique (19) est monté dans une gorge (20) prévue sur la face supérieure du méplat horizontal (18). Une autre gorge (21) peut également être prévue sur la face supérieure de la bride intermédiaire (11), au niveau de son rebord interne, pour recevoir le méplat horizontal (18) et ainsi maintenir la bague d'étanchéité (17) en position. La bague d'étanchéité (17) est préférentiellement fabriquée en PTFE, PFA ou TFM.A second seal (16) is also provided between the upper face of the intermediate flange (11) and the underside of the buffer (5). This second seal (16) may comprise a sealing ring (17) mounted on the opening of the intermediate flange (11), comprising a horizontal flattening (18) resting on the upper face of the intermediate flange ( 11). An O-ring (19) is mounted in a groove (20) provided on the upper face of the horizontal flat (18). Another groove (21) may also be provided on the upper face of the intermediate flange (11), at its inner rim, to receive the horizontal flat (18) and thus maintain the sealing ring (17) in position . The sealing ring (17) is preferably made of PTFE, PFA or TFM.
Le dispositif d'ouverture/fermeture (1) rapide de l'invention comprend également des systèmes de verrouillage (22) qui sont montés sur la bride intermédiaire (11). Le dispositif (1) de l'invention comprend préférentiellement trois systèmes de verrouillage (22) qui sont répartis en triangle de manière équidistante sur le pourtour de la bride intermédiaire (11). The fast opening / closing device (1) of the invention also comprises locking systems (22) which are mounted on the intermediate flange (11). The device (1) of the invention preferably comprises three locking systems (22) which are distributed in a triangle equidistantly around the periphery of the intermediate flange (11).
Il est bien entendu possible de prévoir un nombre différent de systèmes de verrouillage, notamment en fonction du diamètre de l'ouverture (3) de trou d'homme (2, 6). L'utilisation d'un plus grand nombre de systèmes de verrouillage (22) augmente le coût du dispositif (1) et le temps nécessaire à sa manipulation en ouverture et en fermeture, tandis que l'utilisation d'un plus faible nombre de systèmes de verrouillage (22) affecte négativement l'étanchéité du dispositif (1) en position fermée.It is of course possible to provide a different number of locking systems, in particular according to the diameter of the opening (3) of manhole (2, 6). The use of a larger number of locking systems (22) increases the cost of the device (1) and the time required for its manipulation in opening and closing, while the use of a smaller number of systems locking device (22) negatively affects the sealing of the device (1) in the closed position.
Selon un exemple de mise en oeuvre de l'invention, le dispositif d'ouverture/fermeture comprend au moins trois systèmes de verrouillage répartis en triangle de manière équidistante sur le pourtour de la bride intermédiaire. Selon les diamètres de l'ouverture de trou d'homme, le nombre de systèmes de verrouillage pourra être variable.According to an exemplary implementation of the invention, the opening / closing device comprises at least three locking systems distributed in a triangle equidistantly around the periphery of the intermediate flange. Depending on the diameters of the manhole opening, the number of locking systems may be variable.
Les systèmes de verrouillage (22) de l'invention sont de préférence sous la forme de systèmes de manivelles à came (23), dont chaque came (24) est prévue pour venir se positionner au-dessus du tampon (5) par pivotement puis venir en appui sur celui-ci pour assurer sa fermeture, l'ouverture se faisant par le déplacement inverse.The locking systems (22) of the invention are preferably in the form of cam crank systems (23), each cam (24) is provided to be positioned above the buffer (5) by pivoting and then come to bear on it to ensure its closure, the opening being done by the reverse movement.
Chaque système de manivelles à came (23) comporte une embase (25) prévue pour être solidarisée par vissage ou par soudage sur la face supérieure de la bride intermédiaire (11). Each cam crank system (23) comprises a base (25) provided to be secured by screwing or welding on the upper face of the intermediate flange (11).
Chaque système de manivelles à came (23) comprend également un organe de manipulation (26), par exemple pourvu de poignées (27) permettant de facilement lui transmettre un couple de rotation. Cet organe de manipulation (26) est prévu en partie supérieure de chaque système (23) et présente un volume creux (28) central cylindrique fileté prévu pour être engagé sur le filetage complémentaire d'une tige verticale filetée (29) montée sur la bride intermédiaire (11), à travers l'embase (25). Cette tige verticale filetée (29) est maintenue en place par une vis d'immobilisation (30) qui vient appuyer transversalement sur son filetage, ce qui empêche également sa rotation.Each cam crank system (23) also comprises a handling member (26), for example provided with handles (27) to easily transmit a torque to it. This manipulation member (26) is provided in the upper part of each system (23) and has a threaded cylindrical central hollow space (28) intended to be engaged on the complementary thread of a vertical threaded rod (29) mounted on the flange. intermediate (11), through the base (25). This vertical threaded rod (29) is held in place by an immobilizing screw (30) which bears transversely on its thread, which also prevents its rotation.
Une bague tournante (31) comportant une came (24) est montée autour de la partie inférieure de l'organe de manipulation (26), avec une partie se prolongeant vers le bas au-delà de l'organe de manipulation (26) pour former un retour en direction de la tige verticale filetée (29). A rotating ring (31) having a cam (24) is mounted around the lower portion of the manipulator (26), with a portion extending downwardly beyond the manipulator (26) for form a back towards the vertical threaded rod (29).
Un autre dispositif de maintien (32), par exemple sous la forme d'un torique fendu (33), est logé dans deux gorges (34, 35) en vis-à-vis, à savoir une gorge (34) prévue sur le flanc interne de la bague tournante (31) et une gorge (35) prévue sur le flanc externe de l'organe de manipulation (26), permettant ainsi, après assemblage de l'organe de manipulation (26) dans la bague tournante (31), de rendre ces deux pièces (26, 31) mutuellement inamovibles.Another holding device (32), for example in the form of a split ring (33), is housed in two grooves (34, 35) facing each other, namely a groove (34) provided on the internal flank of the rotating ring (31) and a groove (35) provided on the outer side of the manipulation member (26), thus allowing, after assembly of the manipulation member (26) in the rotating ring (31); ), to make these two pieces (26, 31) mutually irremovable.
La bague tournante (31) comporte une came (24) prévue pour verrouiller le tampon (5) lorsqu'elle est pivotée en position de fermeture et pour dégager le tampon (5) lorsqu'elle est pivotée en position d'ouverture.The rotating ring (31) has a cam (24) for locking the pad (5) when pivoted in the closed position and for disengaging the pad (5) when pivoted to the open position.
La bague tournante (31) est entraînée à rotation par un joint à friction (37) prévu entre la bague tournante (31) et l'organe de manipulation (26) de sorte que lorsque l'organe de manipulation (26) est pivoté, la bague tournante (31) est également pivotée. Le joint à friction (37) est préférentiellement logé en partie supérieure de la bague tournante (31) afin de protéger des roulements (38) montés entre l'organe de manipulation (26) et l'organe de manipulation (26). The rotating ring (31) is rotated by a friction seal (37) provided between the rotating ring (31) and the manipulator (26) so that when the manipulator (26) is rotated, the rotating ring (31) is also rotated. The friction seal (37) is preferably housed in the upper part of the rotating ring (31) in order to protect bearings (38) mounted between the manipulation member (26) and the manipulation member (26).
Ces roulements (38) sont prévus verticalement et horizontalement entre les surfaces de contact de l'organe de manipulation (26) avec l'organe de manipulation (26) afin de guider le pivotement de la bague tournante (31) autour de l'organe de manipulation (26) et de la tige verticale filetée (29) These bearings (38) are provided vertically and horizontally between the contact surfaces of the manipulation member (26) with the manipulation member (26) to guide the pivoting of the rotating ring (31) around the member manipulator (26) and vertical threaded rod (29)
L'embase (25) de chaque système de manivelles à came (23) comprend également une bague de butée (39) montée fixe sur la tige verticale filetée (29). Cette bague de butée (39) est logée dans l'embase (25) de manière à ce que son rebord supérieur (40) fasse saillie au-dessus de l'embase (25). Ce rebord supérieur en saillie (40) est reçu dans un logement central (41) de forme complémentaire prévu dans le rebord inférieur de la bague tournante (31). The base (25) of each cam crank system (23) also comprises an abutment ring (39) fixedly mounted on the vertical threaded rod (29). This stop ring (39) is housed in the base (25) so that its upper flange (40) protrudes above the base (25). This protruding upper rim (40) is received in a central recess (41) of complementary shape provided in the lower rim of the rotating race (31).
Le rebord supérieur en saillie (40) présente une découpe (42), par exemple présente sur un quart de son pourtour, et prévue pour recevoir l'extrémité libre d'une vis, d'un goujon ou de tout autre élément de butée (43), par exemple sensiblement horizontal et prévu transversalement dans la partie inférieure de la bague tournante (31) de sorte que lorsque l'organe de manipulation (26) est pivoté, la bague tournante (31) pivote également, l'élément de butée (43) se déplaçant alors librement dans le volume libre délimité par les flancs verticaux de ladite découpe (42). Pendant cette phase de rotation, par exemple d'un quart de tour, la rotation de l'organe de manipulation (26) fait pivoter la bague tournante (31) de quatre-vingt-dix degrés de sorte que la came (24) de celle-ci s'engage au-dessus du tampon (5) lorsqu'il s'agit d'un pivotement horaire de fermeture, ou se dégage du tampon (5) lorsqu'il s'agit d'un pivotement antihoraire d'ouverture.The protruding upper flange (40) has a cutout (42), for example present on a quarter of its periphery, and adapted to receive the free end of a screw, a stud or any other abutment element ( 43), for example substantially horizontal and provided transversely in the lower part of the rotating ring (31) so that when the handling member (26) is pivoted, the rotating ring (31) also pivots, the stop element (43) then moving freely in the free volume defined by the vertical flanks of said cutout (42). During this phase of rotation, for example a quarter turn, the rotation of the manipulation member (26) rotates the rotating ring (31) by ninety degrees so that the cam (24) of it engages above the buffer (5) when it is a closing time pivot, or disengages the buffer (5) when it is a counterclockwise opening pivot.
L'organe de manipulation (26) étant engagé sur le filetage de la tige verticale filetée (29), sa rotation le fait descendre conjointement avec la bague tournante (31) lorsqu'il s'agit d'un pivotement horaire de fermeture ou le fait remonter conjointement avec la bague tournante (31) lorsqu'il s'agit d'un pivotement antihoraire d'ouverture.The manipulation member (26) being engaged on the thread of the vertical threaded rod (29), its rotation causes it to descend together with the rotating ring (31) when it is a closing clockwise pivot or the is raised together with the rotating ring (31) when it is a counterclockwise pivoting opening.
Lorsque l'élément de butée (43) arrive en fin de découpe (42), sa butée contre un des deux flancs verticaux de la découpe (42) empêche tout pivotement supplémentaire de la bague tournante (31) lorsque l'opérateur continue de tourner l'organe de manipulation (26). When the abutment element (43) reaches the end of cutting (42), its abutment against one of the two vertical flanks of the cutout (42) prevents any further pivoting of the rotating race (31) when the operator continues to turn the manipulation member (26).
Manipuler l'organe de manipulation (26) en rotation le fait alors seulement se déplacer conjointement avec la bague tournante (31), vers le bas lorsqu'il s'agit d'un pivotement horaire de fermeture, ou vers le haut lorsqu'il s'agit d'un pivotement antihoraire d'ouverture.Manipulating the manipulator (26) in rotation then only makes it move together with the rotating ring (31), down when it is a closing time pivot, or upward when This is a counter-clockwise rotation.
Le pivotement horaire de fermeture permet alors de faire appuyer la came (24) sur le dessus du tampon (5) pour le verrouiller en fermeture.The closing clockwise pivot then makes it possible to press the cam (24) on top of the buffer (5) to lock it in closing.
Grâce au seul pivotement horaire ou antihoraire, chaque système de manivelles à came (23) permet ainsi de verrouiller ou de déverrouiller le tampon (5), ce qui fait à la fois pivoter la came (24) pour la mettre dans une position adaptée au verrouillage ou au déverrouillage du tampon (5), et à la fois descendre ou remonter la came (24) pour la faire appuyer sur le tampon (5) ou l'en dégagerThanks to the single clockwise or counterclockwise pivoting, each cam crank system (23) thus makes it possible to lock or unlock the buffer (5), which both pivots the cam (24) to a position adapted to the cam (24). locking or unlocking the buffer (5), and at the same time lowering or raising the cam (24) so as to press it on the buffer (5) or to disengage it
Dans la variante de l'invention représentée sur les figures, la découpe (42), du rebord supérieur (40) de la bague de butée (39) est présente sur un quart de son pourtour, ce qui se traduit par un pivotement d'un quart de tour de la came (24) pour la déplacer de sa position d'ouverture à sa position de verrouillage à sa position de verrouillage, et inversement.In the variant of the invention shown in the figures, the cutout (42) of the upper rim (40) of the stop ring (39) is present on a quarter of its periphery, which results in a pivoting of a quarter of a turn of the cam (24) to move from its open position to its locking position to its locking position, and vice versa.
L'homme du métier pout bien entendu adapter l'invention pour un déplacement différent, par exemple avec une découpe (42) présente sur la moitié du pourtour du rebord supérieur (40) pour un pivotement d'un demi-tour de la came (24) pour la déplacer d'une position d'ouverture à une position de verrouillage, et inversement.Those skilled in the art can of course adapt the invention for a different displacement, for example with a cutout (42) present on the half of the periphery of the upper flange (40) for pivoting a half-turn of the cam ( 24) to move it from an open position to a lock position, and vice versa.
De manière générale, il est évident que la présente description ne se limite pas aux exemples explicitement décrits, mais comprend également d'autres modes de réalisation et/ou de mise en oeuvre. Ainsi, une caractéristique technique décrite peut être remplacée par une caractéristique technique équivalente sans sortir du cadre de la présente invention et une étape décrite de mise en oeuvre du procédé peut être remplacée par une étape équivalente sans sortir du cadre de l'invention tel que défini par les revendications.In general, it is obvious that the present description is not limited to the examples explicitly described, but also includes other embodiments and / or implementation. Thus, a described technical characteristic can be replaced by an equivalent technical characteristic without departing from the scope of the present invention and a described step of implementing the method can be replaced by an equivalent step without departing from the scope of the present invention. the invention as defined by the claims.
Bien que le dispositif d'ouverture/fermeture (1) rapide de l'invention prévu pour le trou d'homme (2, 6) d'un réacteur chimique (7) émaillé, il est évident pour l'homme du métier de l'adapter à tout type de tubulure ou de piquage (2), pour la fermeture à l'aide d'un tampon (5) de n'importe quelle ouverture (3) bordée par une bride (4) ou un rebord.Although the quick opening / closing device (1) of the invention provided for the manhole (2, 6) of an enameled chemical reactor (7) , it is obvious to those skilled in the art adapting to any type of tubing or stitching (2), for closure with a buffer (5) of any opening (3) bordered by a flange (4) or a flange.
