The two ends of the ring have guide surfaces (13, 14) designed to centre it in relation to the valve housing, with the rear section (7) of guide (14) acting as the seat for the valve shutter (6).

Description

- Rondelle de sureté de présence de battant de clapet antiretour ouvrable rapidement
L'invention consiste en une rondelle de sureté, de forme particulière, solidaire du battant d'un clapet anti retour dont la présence est indispensable à l'étanchéité des deux parties du corps.
- Safety washer for the presence of a rapidly opening non-return valve leaf
The invention consists of a safety washer, of particular shape, secured to the leaf of a non-return valve, the presence of which is essential for sealing the two parts of the body.

Les clapets anti-retour tels que décrits dans les brevets 90 13422 et 91 11589, sont, de part leur conception, ouverts couramment à des fins de lavage et d'inspection. The check valves as described in patents 90 13422 and 91 11589 are, by design, commonly opened for washing and inspection purposes.

Lors de ces opérations, le battant y est extrait puis réintroduit avant la fermeture du corps par un verrou circulaire. Toutefois il est possible de refermer le corps et de remettre l'installation en service, sans y avoir réintroduit le battant, pouvant ainsi causer de graves préjudices.During these operations, the leaf is extracted there and then reintroduced before the body is closed by a circular lock. However, it is possible to close the body and return the installation to service, without having reintroduced the leaf, which could cause serious damage.

L'invention a pour but de rendre le battant indispensable à l'étanchéité entre les deux parties du corps. The invention aims to make the leaf essential for sealing between the two parts of the body.

L'invention est caractérisée par l'adjonction d'une sorte de rondelle, dans laquelle coulisse le battant. Elle est Pincée entre les deux parties du corps de clapet. Elle est solidarisée au battant par un jonc d'arret placé sur les lamelles de guidage du battant. The invention is characterized by the addition of a kind of washer, in which the leaf slides. It is pinched between the two parts of the valve body. It is secured to the leaf by a stop ring placed on the leaf guiding strips.

Pour empécher toute fermeture du corps de clapet sans la présence de la rondelle de sureté, le développement de l'invention qui en tient compte est caractérisé en ce que l'épaisseur de la rondelle, comprise entre ses deux faces de pincement, est supérieure à la distance de serrage possible par le verrou circulaire qui maintient entre-elles, les deux parties du corps de clapet. To prevent any closure of the valve body without the presence of the safety washer, the development of the invention which takes this into account is characterized in that the thickness of the washer, comprised between its two gripping faces, is greater than the possible clamping distance by the circular lock which holds the two parts of the valve body between them.

Pour empêcher toute insertion de la rondelle de sureté sans le battant, un développement de l'invention qui en compte prévoit qu'un jonc d'arret, soit apposé sur les lamelles de guidage du battant, et en ce que le démontage de ce jonc d'arret, nécessite un outillage spécifique que l'opérateur n'utilise pas pour ouvrir ou fermer le corps. To prevent any insertion of the safety washer without the leaf, a development of the invention which takes this into account provides that a stop ring is affixed to the guide strips of the wing, and in that the disassembly of this ring stop, requires specific tools that the operator does not use to open or close the body.

Pour délimiter le recul maximum du battant, un développement de l'invention qui en tient compte est caractérisé en ce que le positionnement du jonc d'arret sur les lamelles de guidage est tel que sa butée contre la rondelle corresresponde à l'ouverture maximum du battant. To delimit the maximum recoil of the leaf, a development of the invention which takes account of it is characterized in that the positioning of the stop ring on the guide strips is such that its abutment against the washer corresponds to the maximum opening of the beating.

Pour assurer une bonne étanchéité entre le battant et la rondelle, il convient que celle-ci soit correctement centrée sur l'emmanchement d'amont, un développement de l'invention qui en tient compte, prévoit, à la base de la face amont de la rondelle, un prolongement de guidage apte à s'emboiter dans l'emmanchement d'amont du corps de clapet. To ensure a good seal between the leaf and the washer, the latter should be correctly centered on the upstream fitting, a development of the invention which takes this into account, provides, at the base of the upstream face of the washer, a guide extension capable of fitting into the upstream fitting of the valve body.

Pour ne pas perturber le déplacement de la tete du battant à l'intérieur du corps de clapet. il est impératif que l'emmanchement d'amont avec la rondelle soit correctement centre dans le corps de clapet. Un développement de l'invention qui en tient compte Prévoit, pour la face aval de la rondelle, un prolongement de centrage, apte à s'emboiter dans l'entrée de la partie aval du corps de clapet. In order not to disturb the movement of the head of the leaf inside the valve body. it is imperative that the upstream fitting with the washer is correctly centered in the valve body. A development of the invention which takes this into account Provides, for the downstream face of the washer, a centering extension, capable of fitting into the inlet of the downstream part of the valve body.

Pour assurer la fonction principale de clapet antiretour compte tenu de l'adjonction de la rondelle de sureté, un développement de l'invention qui en tient compte prévoit que l'extrémité aval du guide de centrage d'aval, dans le sens de déplacement du fluide, soit le siège de la tete du battant. To ensure the main function of non-return valve taking into account the addition of the safety washer, a development of the invention which takes account of this provides that the downstream end of the downstream centering guide, in the direction of movement of the fluid, or the seat of the wing head.

Pour obtenir une bonne étanchéité entre le siège et la tete du battant, il convient qu'il soit correctement guidé. To obtain a good seal between the seat and the head of the leaf, it should be correctly guided.

Un développement de l'invention qui en tient compte est carcérisé en ce que l'alésage de la rondelle de sureté est guide de centrage et de coulissement des lamelles du battant.A development of the invention which takes this into account is characterized in that the bore of the safety washer is a guide for centering and sliding the blades of the leaf.

On explique maintenant, plus précisement l'invention à propos des dessins annexés, dans lesquels; la figure 1 représente, en coupe longitudinale, un clapet anti retour ouvrable rapidement pourvu d'une rondelle de sureté de présence de battant; la figure 2 représente, en coupe et à plus grande échelle, le battant en position d'ouverture maximum, solidarisé à la rondelle de sureté par le jonc d'arret. The invention will now be explained more precisely with reference to the accompanying drawings, in which; FIG. 1 shows, in longitudinal section, a rapidly opening non-return valve provided with a safety washer for the presence of a leaf; Figure 2 shows, in section and on a larger scale, the leaf in the maximum open position, secured to the safety washer by the stop ring.

Sur la figure 1 on a désigné par 1 l'emmanchement d'amont par 2 le verrou circulaire qui, en s'agrippant derrière les crochets 3, relie entre elles, la partie 1 et la partie 4 qui est la partie aval du corps de clapet, par 5 les lamelles de guidage du battant, par 6 la tete du battant qui épouse le siège 7 de la rondelle de sureté 8, par 9 le jonc d'arret et de solidarisation de la rondelle 8 au battant ainsi formé par la tete 6 et les lamelles de guidage 5, et par 10 le ressort de rappel du battant. In Figure 1 is designated by 1 the upstream fitting by 2 the circular latch which, by gripping behind the hooks 3, connects between them, part 1 and part 4 which is the downstream part of the body of flap, by 5 the leaf guiding strips, by 6 the head of the leaf which marries the seat 7 of the safety washer 8, by 9 the stop ring and the connection of the washer 8 to the leaf thus formed by the head 6 and the guide blades 5, and by 10 the return spring of the leaf.

Sur la figure 2 on a désigné par 5 les lamelles de gui dage du battant, par 6 la tete du battant, par 7 le siège de la rondelle 8, par 9 le jonc d'arret et de solidarisation, représenté ici en position de butée de fin de course du battant, par 11 la face amont de Pincement, par 12 le joint d'étanchéité formant la face d'aval de la rondelle de sureté, par 14 le prolongement de guidage d'amont qui s'emboite dans l'emmanchement d'entrée 1, par 14 le prolongement de guidage d'aval, de la rondelle de sureté, qui s'emboite dans l'entrée du corps de clapet 4 pour centrer la rondelle de sureté et par 15 l'alésage intérieur de la rondelle (8) qui sert de guide de centrage et de coulissement des lamelles (5) du battant. In FIG. 2, the guiding strips for the leaf are designated by 5, by 6 the head of the leaf, by 7 the seat of the washer 8, by 9 the stop and fastening ring, shown here in the stop position. end of stroke of the leaf, by 11 the upstream face of Pinching, by 12 the seal forming the downstream face of the safety washer, by 14 the upstream guide extension which fits into the inlet fitting 1, by 14 the downstream guide extension, of the safety washer, which fits into the inlet of the valve body 4 to center the safety washer and by 15 the internal bore of the washer (8) which serves as a guide for centering and sliding the blades (5) of the leaf.

Après l'ouverture du corps et l'extraction du battant à des fins de lavage ou d'inspection, et compte tenu de la solidarisation du battant (5 et 6) à la rondelle de sureté 8 le jonc d'arret 9 d'une part, et compte tenu que l'épaisseur entre les parties 11 et 12 de la rondelle de sureté 8 est supérieure aux possibilités de serrage par le verrou circulaire 2 d'autre part, il ne sera pas possible d'obtenir une étanchéité entre les parties 1 et 4 du corps de clapet sans y avoir réintroduit le battant solidarisé à la rondelle 8. After opening the body and extracting the leaf for washing or inspection purposes, and taking into account the connection of the leaf (5 and 6) to the safety washer 8 the stop ring 9 of a part, and given that the thickness between the parts 11 and 12 of the safety washer 8 is greater than the possibilities of tightening by the circular lock 2 on the other hand, it will not be possible to obtain a seal between the parts 1 and 4 of the valve body without having reintroduced the flap secured to the washer 8.

Ainsi, la rondelle de sureté 8 est l'organe d'étanchéité indispensable entre les parties 1 et 4 du corps de clapet, elle est aussi le siège d'étanchéité 7 du battant ainsi son guide de coulissement, elle est enfin l'organe centreur entre les parties 1 et 4 par ses guides de centrage 13 et 14.Thus, the safety washer 8 is the essential sealing member between the parts 1 and 4 of the valve body, it is also the sealing seat 7 of the leaf and its sliding guide, it is finally the centering member. between parts 1 and 4 by its centering guides 13 and 14.

Outre la fonction de solidarisation entre le battant et la rondelle de sureté, le jonc 9 est l'organe de butée de fin de course du battant. In addition to the securing function between the leaf and the safety washer, the rod 9 is the end of stroke stop member of the leaf.

L'invention s'applique principalement au clapet antiretour ouvrable rapidement.  The invention mainly applies to the rapidly opening non-return valve.
