Abstract

The invention relates to a device for rapidly plugging openings allowing access to the filters in gas pipes. It is made up of a plate 2 coming into abutment on a shoulder inside the flange to be welded 1 where a slope at 45 DEG has also been made to house the sealing gasket 11. Three keys 6 integral with the plate 2 serve to guide three sectors 3. These each have an oblique groove in which there slides a finger 5 integral with a lock bolt 4. By turning the handle 10, the three sectors are simultaneously moved apart and become wedged at the end of their travel onto a tapered machining in the component 1. The pin 9 limits the travel of the lock bolt. In the closed position, a stop-piece 8 as well as a bleed screw 7 prevent the assembly under pressure from being dismantled.

Description

Tout gaz, à un moment donné, a besoin d'être filtré en vue de son exploitation ou réexploitation ; des filtres doivent être mis en place, changés régulièrement, rapidement et en toute sécurité, d'où l'utilité de portes à ouvertures rapides d'accès à ceux-ci. Any gas, at a given moment, needs to be filtered for its exploitation or re-exploitation; filters must be installed, changed regularly, quickly and safely, hence the usefulness of doors with quick access to them.

Plusieurs réalisations sont connues à ce jour, par exemple
- Le système de couvercle vissé étanche sur une bride, présente l'avantage d'être une réalisetion simple, malgré tout de même, un usinage délicat du filetage.Several achievements are known to date, for example
- The tight screwed cover system on a flange, has the advantage of being a simple realization, despite all the same, delicate machining of the thread.

En effet, le filetage doit comporter un jeu non négligeable afin de pallier à la déformation ultérieure due à la soudure de la bride sur son support, mais il doit assurer un minimum de filets en prise car ce sont eux qui résistent à la pression. De plus, lors du montage et démontage du
couvercle, il est nécessaire d'effectuer plusieurs tours du couvercle par rapport à la bride, nécessitant un milieu ambiant propre, ce qui est rarement le cas.Indeed, the threading must include a significant play in order to compensate for the subsequent deformation due to the welding of the flange on its support, but it must ensure a minimum of threads in engagement because they are the ones which resist the pressure. In addition, during assembly and disassembly of the
cover, it is necessary to make several turns of the cover with respect to the flange, requiring a clean ambient environment, which is rarely the case.

- Le système se rapprochant le plus de notre invention est composé de trois pièces principales. - The system closest to our invention is made up of three main parts.

Un plateau vient en butée sur un épaulement à l'intérieur d'une bride à souder, une étanchéité est assurée entre ces deux pièces. Un couvercle, dans lequel des crans ont été usinés sur son diamètre extérieur, vient se loger sur le plateau à l'intérieur de la bride à souder. Celle-ci comporte les mêmes crans en intérieur afin de pouvoir insérer le couvercle dans la bride à souder. Une petite rotation du couvercle par rapport à la bride permet la fermeture rapide de l'ensemble. A plate abuts on a shoulder inside a welding flange, a seal is provided between these two parts. A cover, in which notches have been machined on its outside diameter, is housed on the plate inside the flange to be welded. It has the same notches inside to be able to insert the cover into the flange to be welded. A small rotation of the cover relative to the flange allows the fast closing of the assembly.

Ce principe de crans, très pratique à l'utilisation, a l'inconvénient majeur de nécessiter une exécution délicate. De plus, il demande un surplus matière afin de résister à la pression d'où augmentation du coûtet surtout de l'encombrement. En effet, un pas de crantage comporte une partie matière ou "pleine" et une partie sans matière. Pour introduire le couvercle à l'intérieur de la bride, il faut faire correspondre une partie "pleine" du couvercle avec une partie sans matière de la bride. Pour résister à une pression donnée, il faut compenser la partie sans matière par une augmentation de la partie "pleine" qui, elle, subit tous les efforts. This principle of notches, very practical in use, has the major drawback of requiring delicate execution. In addition, it requires extra material in order to resist the pressure, hence the cost and especially the bulk. Indeed, a notching pitch has a material or "solid" part and a part without material. To insert the cover inside the flange, you must match a "full" part of the cover with a non-material part of the flange. To resist a given pressure, it is necessary to compensate the part without matter by an increase in the "full" part which, it, undergoes all the efforts.

Selon l'invention, une rotation type "quart de tour" effectuée par l'opérateur, est transformée en une translation de trois secteurs circulaise logeant dans leur mouvement dans une gorge de la bride à souder, assurant ainsi un verrouillage, tout en nécessitant que le minimum de matière par rapport au calcul de résistance à une pression donnée.  According to the invention, a rotation type "quarter turn" performed by the operator, is transformed into a translation of three circulais sectors housed in their movement in a groove of the flange to be welded, thus ensuring locking, while requiring that the minimum of material compared to the calculation of resistance to a given pressure.

Les trois secteurs résultant de la division d'une couronne, et disposés à
1200, comportent sur leurs arcs extérieurs, une pente définissant une
surface tronconique d'appui sur une surface de pente correspondante, prévue
sur la bride à souder, de manière à assurer, lors du verrouillage, l'écrasement du joint d'étanchéité. Afin d'assurer la transformation du
mouvement de rotation "quart de tour" en une translation, une rainure
oblique est usinée sur chaque secteur selon un angle adéquat, de manière à
assurer le verrouillage rapide sans coincement.The three sectors resulting from the division of a crown, and arranged to
1200, have on their outer arches a slope defining a
frustoconical bearing surface on a surface of corresponding slope, provided
on the flange to be welded, so as to ensure, during locking, the crushing of the seal. In order to ensure the transformation of
"quarter turn" rotational movement in translation, groove
oblique is machined on each sector at an adequate angle, so that
ensure quick locking without jamming.

Il est à signaler que les trois secteurs résultent de la division d'une couronne en trois, moins un dégagement radial entre chaque secteur, d'une
longueur permettant de loger la butée maintenue par la vis de purge en
position de verrouillage.It should be noted that the three sectors result from the division of a crown into three, minus a radial clearance between each sector, from a
length to accommodate the stop held by the bleed screw
locking position.

all in middle position.

Le plateau (Rep. 2) vient se loger en butée sur un épaulement (Rep,
18) de la bride à souder (Rep. 1), de sorte qu'un joint d'étanchéité
(Rep. 11) vienne se loger dans la partie (Rep. 12) usinée à 450 dans la bride (Rep. 1). Trois secteurs (Rep. 3) usinés à partir de la même couronne coulissent sur la partie haute du plateau (Rep. 2) à l'aide de trois clavettes (Rep. 6) fixées sur ledit plateau et de trois rainures (Rep. 17) usinées sur les secteurs (Rep. 3).The plate (Rep. 2) is housed in abutment on a shoulder (Rep,
18) of the welding flange (Item 1), so that a seal
(Rep. 11) is housed in the part (Rep. 12) machined at 450 in the flange (Rep. 1). Three sectors (Rep. 3) machined from the same crown slide on the upper part of the plate (Rep. 2) using three keys (Rep. 6) fixed on said plate and three grooves (Rep. 17 ) machined on the sectors (Rep. 3).

Un verrou rotatif (Rep. 4) vient coiffer les trois secteurs (Rep. 3). A rotary lock (Rep. 4) covers the three sectors (Rep. 3).

Des pions (Rep. 5) sont solidaires du verrou (Rep. 4) et se positionnent dans des rainures obliques et rectilignes (Rep. 13) usinées dans les trois secteurs (Rep. 3) de sorte qu'en position repos, ces secteurs viennent buter centralement par leur face intérieure sur une partie centrale du verrou (Rep. 4). Ces rainures (Rep. 13) sont disposées selon un angle préférentiel de 650 plus ou moins 100 par rapport au plan radial vertical passant par le milieu du secteur concerné.Pawns (Rep. 5) are integral with the latch (Rep. 4) and are positioned in oblique and rectilinear grooves (Rep. 13) machined in the three sectors (Rep. 3) so that in the rest position, these sectors abut centrally by their inner face on a central part of the lock (Rep. 4). These grooves (Ref. 13) are arranged at a preferred angle of 650 plus or minus 100 relative to the vertical radial plane passing through the middle of the sector concerned.

Ainsi monté, lorsque l'utilisateur, grâce à une clé de manoeuvre
(Rep. 10), tourne le verrou d'environ un quart de tour, le mouvement de rotation est transformé en un mouvement de translation radiale extérieure des trois secteurs (Rep. 3) par l'intermédiaire des pions (Rep. 5) coulissants dans les rainures (Rep. 13). De ce fait, ces trois secteurs (Rep. 3) en s'écartant, rentrent dans une gorge (Rep. 14) prévue sur la face intérieure de la bride à souder (Rep. 1). So mounted, when the user, thanks to an operating key
(Rep. 10), turns the bolt about a quarter of a turn, the rotational movement is transformed into a movement of external radial translation of the three sectors (Rep. 3) via the sliding pins (Rep. 5) in the grooves (Ref. 13). Therefore, these three sectors (Rep. 3), deviating, enter a groove (Rep. 14) provided on the inner face of the flange to be welded (Rep. 1).

Les trois secteurs (Rep. 3) comportent sur leur partie supérieure de leur arc extérieur, une partie en pente définissant une surface tronconique d'appui sur une surface correspondante prévue sur la face supérieure de la gorge (Rep. 14) de manière à faciliter le coincement et permettant de presser le joint d'étanchéité (Rep. 11) lors du verrouillage. Un mouvement de rotation inverse du verrou (Rep. 4) permet de dévérouiller les trois secteurs (Rep. 3) de la bride à souder (Rep.1). Un axe (Rep. 9) formant butée, (Rep. 15) est vissé sur un épaulement central (Rep. 16) du plateau limite le jeu axial du verrou (Rep. 4). La vis de purge (Rep. 7) et la butée (Rep. 8) qu'elle supporte coopèrent avec les faces latérales radiales des secteurs. Lesdits vis (Rep. 7) et butée (Rep. 8) sont fixées sur le plateau (Rep. 2) entre deux secteurs (Rep. 3), dans la position relative écartée de verrouillage de ces derniers. Ainsi, le système ne peut être débloqué que si la vis (Rep. 7) et la butée (Rep. 8) sont enlevées, car le débloquage nécessite le retour en position centrale des secteurs et le rapprochement de leurs faces radiales qui viendrait en contact avec la butée (Rep. 8), d'où une sécurité pour l'utilisateur.  The three sectors (Rep. 3) have on their upper part of their external arc, a sloping part defining a frustoconical surface of support on a corresponding surface provided on the upper face of the groove (Rep. 14) so as to facilitate jamming and allowing the seal to be pressed (Ref. 11) during locking. A reverse rotation movement of the bolt (Rep. 4) enables the three sectors (Rep. 3) of the weld-on flange to be unlocked (Rep. 1). An axis (Rep. 9) forming a stop (Rep. 15) is screwed onto a central shoulder (Ref. 16) of the plate limits the axial play of the lock (Rep. 4). The bleed screw (Rep. 7) and the stop (Rep. 8) which it supports cooperate with the radial lateral faces of the sectors. Said screws (Rep. 7) and stop (Rep. 8) are fixed on the plate (Rep. 2) between two sectors (Rep. 3), in the relative locking position apart from the latter. Thus, the system can only be unlocked if the screw (Rep. 7) and the stop (Rep. 8) are removed, because the unlocking requires the sectors to return to the central position and the bringing together of their radial faces which would come into contact with the stop (Rep. 8), which provides security for the user.
