Abstract

Une chemise en élastomère (4) revêt le boîtier (1) du robinet, qui ressort radialement des faces frontales du boîtier (1) de robinet et sert d'étanchéité aux brides, des bourrelets (5) de bordure de la chemise (4) disposés dans les régions des brides, étant supportés par des appuis, prévus dans le boîtier (1). L'invention permet de réduire le travail nécessaire jusqu'à présent pour la réalisation des appuis, du fait que ceux-ci sont formés par des anneaux indéformables (6) qui sont insérés dans la chemise. Les détalonnages nécessaires dans les boîtiers connus et destinés à loger et à soutenir la chemise en élastomère, sont donc superflus.An elastomeric jacket (4) covers the valve housing (1), which emerges radially from the end faces of the valve housing (1) and serves as a seal for the flanges, the beads (5) on the edge of the jacket (4) arranged in the regions of the flanges, being supported by supports, provided in the housing (1). The invention makes it possible to reduce the work necessary until now for the production of the supports, owing to the fact that these are formed by non-deformable rings (6) which are inserted into the sleeve. The reliefs required in known housings intended to house and support the elastomeric jacket are therefore superfluous.

Description

À La présente invention concerne un robinet d'arrêt comportant une chemiseThe present invention relates to a shut-off valve comprising a jacket

en matériau élastomère, revêtant son boîtier, qui ressort radialement des faces frontales du boîtier et sert d'étanchéité aux brides, des bourrelets de bordure de la chemise, disposés dans les régions des brides, étant supportés  made of elastomeric material, covering its housing, which protrudes radially from the front faces of the housing and serves as a seal for the flanges, the edges of the jacket edge, arranged in the regions of the flanges, being supported

par des appuis, prévus dans le boîtier.  by supports, provided in the housing.

Un avantage important des robinets d'arrêt centrés, avec chemise en élastomère, réside dans le fait qu'un robinet de ce type n'a pas besoin d'organes d'étanchéité de bride supplémentaires. La chemise en élastomère est telle qu'elle peut assurer cette fonction. A cet effet, elle ressort des faces frontales du boîtier de robinet; lorsque le boîtier de robinet est monté,  An important advantage of centered shut-off valves with an elastomer jacket is that a valve of this type does not require additional flange seals. The elastomer shirt is such that it can perform this function. For this purpose, it emerges from the front faces of the valve housing; when the valve housing is fitted,

cette partie de la chemise est pressée contre la bride adjacente.  this part of the shirt is pressed against the adjacent flange.

Il faut toutefois signaler que le serrage simple décrit n'est pas suffisant pour toutes les conditions de service. Dans le cas d'une dépression à l'intérieur du boîtier de robinet, une force dirigée vers l'intérieur, agit sur la chemise du robinet. Pour éviter que la chemise ne soit progressivement  It should be noted, however, that the simple tightening described is not sufficient for all operating conditions. In the event of a vacuum inside the valve housing, a force directed inwards acts on the valve jacket. To prevent the shirt from being gradually

extraite de sa fixation, il faut prévoir des appuis dans le boîtier de robinet.  extracted from its fixing, it is necessary to provide supports in the tap housing.

Ces appuis qui sont connus dans différentes variantes sont constitués, pour l'essentiel, de barrettes qui sont formées par des détalonnages des faces frontales du boîtier de robinet (par ex. brevets DE 32 03 374, EP 103 070 et US 35 40 691). Des bourrelets de bordure de la chemise en élastomère s'engagent dans les détalonnages. Lorsque le boîtier de robinet est monté, ils  These supports, which are known in different variants, essentially consist of bars which are formed by bends of the front faces of the tap housing (for example patents DE 32 03 374, EP 103 070 and US 35 40 691) . Edges of the border of the elastomer shirt engage in the beadings. When the valve housing is mounted, they

sont ma;ntenus par concordance de forme.  are maintained by concordance of form.

Pour réaliser les détalonnages dans le boîtier de robinet, il faut, soit procéder à des opérations supplémentaires, soit adopter des moyens particuliers pour couler le boîtier. Si les détalonnages ne doivent pas être réalisés par usinage mécanique du boîtier, il faut les réaliser en formant un  To carry out the descaling in the valve housing, it is necessary either to carry out additional operations or to adopt special means for pouring the housing. If the uncalibrations are not to be made by mechanical machining of the housing, they must be made by forming a

noyau de coulée séparé ou en disposant à plat le boîtier, lors de la coulée.  separate casting core or by placing the housing flat, during casting.

Dans les deux cas, il n'est pas possible d'avoir une occupation optimale de la  In both cases, it is not possible to have an optimal occupation of the

L'invention se propose de réaliser un robinet d'arrêt du type précité, permettant de rendre superflue la réalisation d'un détalonnage du boîtier de  The invention proposes to produce a stop valve of the aforementioned type, making it unnecessary to carry out a calibration of the housing.

robinet, pour fixer la chemise en élastomère.  tap, to fix the elastomer jacket.

Ce but est atteint suivant l'invention par le fait que les languettes d'appui sont formées par des anneaux indéformables qui sont insérés dans la chemise. Le boîtier du robinet d'arrêt suivant l'invention qui, dans la région d'application de la chemise en élastomère, doit avoir une surface lisse, doit être réalisé à l'aide d'un modèle de coulée qui permette une disposition relativement dense des boîtiers de robinet, avec une division optimale des boîtiers. Il n'est pas nécessaire de procéder à une rectification mécanique de la paroi du boîtier, dans la région de serrage de la chemise bridée. D'une part, les anneaux indéformables insérés sont maintenus dans leur position par la chemise et, d'autre part, ils soutiennent la chemise contre une traction, dirigée vers l'intérieur, de la même manière que les appuis, formés par les  This object is achieved according to the invention by the fact that the support tabs are formed by non-deformable rings which are inserted in the jacket. The stopcock housing according to the invention which, in the region of application of the elastomer jacket, must have a smooth surface, must be produced using a casting model which allows a relatively dense arrangement. faucet housings, with optimal division of the housings. It is not necessary to make a mechanical rectification of the wall of the housing, in the region of tightening of the flanged jacket. On the one hand, the inserted non-deformable rings are held in their position by the jacket and, on the other hand, they support the jacket against a traction, directed inwards, in the same way as the supports, formed by the

détalonnages, dans les robinets d'arrêt connus.  descaling, in known stopcocks.

Les anneaux indéformables peuvent être des anneaux fermés ou ouverts, jointifs frontalement. Les anneaux ouverts présentent des avantages de fabrication et de montage, par rapport aux anneaux fermés. Mais même le montage d'anneaux fermés ne pose pas de problèmes, puisqu'ils peuvent être  The non-deformable rings can be closed or open rings, joined frontally. Open rings have manufacturing and mounting advantages over closed rings. But even the fitting of closed rings poses no problems, since they can be

coupe longitudinale d'un robinet d'arrêt avec chemise en élastomère.  longitudinal section of a stopcock with elastomer jacket.

Ce robinet d'arrêt comporte un boîtier 1 dans lequel un arbre 2 est monté tournant. Sur l'arbre 2 est monté un disque d'obturateur 3. Le boîtier 1 est pourvu d'un revêtement en élastomère 4 dans lequel, à l'état fermé, le  This shut-off valve comprises a housing 1 in which a shaft 2 is mounted to rotate. On the shaft 2 is mounted a shutter disc 3. The housing 1 is provided with an elastomer coating 4 in which, in the closed state, the

disque d'obturateur 3 pénètre avec tout son pourtour.  shutter disc 3 penetrates with its entire periphery.

La chemise en élastomère ressort par les faces frontales du boîtier de robinet 1. Elle possède, à cet endroit, des bourrelets de bordure 5 qui servent d'organes d'étanchéité aux brides, entre le boîtier de robinet et les brides d'une tuyauterie, non représentée. Dans la chemise en élastomère 4 ou derrière les bourrelets 5, on monte des anneaux métalliques 6 qui sont entourés, de tous côtés, par la chemise en élastomère 4 et par le boîtier 1. A l'état monté du robinet d'arrêt, ils constituent une partie des parois logeant les bourrelets 5. Ils empêchent ainsi la chemise en élastomère 4 d'être tirée  The elastomer jacket emerges from the front faces of the valve housing 1. It has, at this point, edge beads 5 which serve as sealing members for the flanges, between the valve housing and the flanges of a pipe. , not shown. In the elastomer jacket 4 or behind the beads 5, metal rings 6 are mounted which are surrounded, on all sides, by the elastomer jacket 4 and by the housing 1. In the assembled state of the shut-off valve, they constitute a part of the walls housing the beads 5. They thus prevent the elastomer jacket 4 from being pulled

vers l'intérieur, dans le cas d'un vide s'établissant dans le boîtier de robinet.  inward, in the event of a vacuum being established in the valve housing.

En cas de pression intérieure, la chemise en élastomère 4 prend appui contre  In the event of internal pressure, the elastomer jacket 4 presses against
