L'invention a pour objet un procédé de montage de vannes dites 2 papillons sur des éléments de tuyauterie. The subject of the invention is a method for mounting so-called 2 butterfly valves on pipe elements.

L'invention trouve une application particulière pour l'équipement de tuyauterie å destination de l'industrie agroalimentaire. re
On a voulu anAllorer l'opération de montage et soudage de vannes papillons sur Tes chantiers, où les ensembles de vannes sont présentés monobloc prêt & souder.The invention finds particular application for piping equipment intended for the food industry. re
We wanted to anAllour the operation of assembly and welding of butterfly valves on your sites, where the valve assemblies are presented in one piece ready & welded.

A cet effet, et selon l'invention, la vanne papillon est livrée en ti t en éléments séparés et démontés comprenant un élément. constituant un flasque avec portée lisse, un second élément constituant une bride support de l'opercule et agencé dans sa partie inférieure avec une portée filetée, et un troisième élément formant bague-écrou avec portée lisse. Selon le procédé de l'invention, on positionne bout a bout par une opération de soudage la portée lisse du flasque contre un tuyau en-regard, puis la portée de la bague écrou avec le second tuyau en regard, on positionne et fixe la bride support de l'opercule sur -le flasque, et on rapproche et fixe par des moyens de liaison appropriés le flasque et la bride support de l'opercule et on adapte la bague écrou sur la portée filetée de ladite bride. For this purpose, and according to the invention, the butterfly valve is delivered in ti t in separate and dismantled elements comprising one element. constituting a flange with a smooth surface, a second element constituting a support flange for the cover and arranged in its lower part with a threaded surface, and a third element forming a ring-nut with a smooth surface. According to the method of the invention, the smooth surface of the flange is positioned end to end by a welding operation against a facing pipe, then the surface of the nut ring with the second facing pipe, the flange is positioned and fixed. support of the cap on the flange, and the flange and the flange support of the cap are brought together and fixed by suitable connecting means, and the nut ring is fitted to the threaded surface of said flange.

Ainsi selon l'invention, le montage est plus rapide et de bnnne qualité. Thus according to the invention, the assembly is faster and of good quality.

Pour fixer l'objet de l'invention illustrée d'une manière non limitative aux figures des dessins où
- La figure 1 est une vue en perspective éclatée des différents éléments de la vanne dite papillon avant montage.To fix the object of the invention illustrated in a non-limiting manner to the figures of the drawings where
- Figure 1 is an exploded perspective view of the various elements of the so-called butterfly valve before assembly.

- la figure 2 est une vue relative à la phase suivante de rapprochement et positionnenent de la bride support de l'opercule sur le premier flasque. - Figure 2 is a view relating to the next phase of approximation and positioning of the support flange of the cover on the first flange.

- Ta figure 3 est une vue relative à la phase suivante de fermeture de la vanne papillon. - Your FIG. 3 is a view relating to the next phase of closing the butterfly valve.

Afin de rendre-plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative aux figurer du dessi n. In order to make the object of the invention more concrete, it will now be described in a non-limiting manner to the figures of the drawing n.

La vanne papillon est référencée dans son ensemble par < 1) et s'adapte par soudure entre deux tuyaux (T1-T2). La vanne comprend un premier élément < 2) comprenant un anneau forant; flasque < 2') de grand diamètre, une partie épaulée (22) avec un évidement < 23) en se prolongeant par un congé de raccordement avec une portée lisse (24) de plus petite section destinée à venir en prolongement et appui bout à bout sur le tuyau (T1) contre lequel elle est soudée. Le second élément < 3 > constitue une bride support de l'opercule (4 > . Cette bride comprend une forme en anneau < 4' > destinée à venir en regard et appui contre la partie complémentaire du premier élément.Cette bride est agencée avec une empreinte pour recevoir l'axe < 5 > d'articulation de l'opercule < 4 > , tandis qu'un joint d'étanchéité est disposé sur la bride pour venir s'auto-centrer dans l'évidement (23). En outre, la bride ' présente dans sa partie arrière une portée filetée (3).La bague écrou (6) vient s'adapter sur la portée (3= > et présente directement ou de manière rapportée une portée (6') extérieure lisse destinée à venir bout å bout avec le second tuyau < T2 > . Un joint d'étanchéité (7) est disposé entre la bague écrou et la portée < 3= > . Le procédé selon l'invention vise à solidariser par soudage l'extrémité du premier élément < 2 > par sa portée lisse bout à bout avec le tuyau (T1) correspondant, à faire de même entre la portée associée (6') à la bague écrou (6) et le second moyen (T2), puis à fixer par boulonnage (8) ou autres moyens de liaison la bride support de l'opercule sur le premier élément < 2) puis à monter la bague écrou sur la portée filetée. The butterfly valve is referenced as a whole by <1) and fits by welding between two pipes (T1-T2). The valve comprises a first element <2) comprising a drilling ring; flange <2 ') of large diameter, a shouldered part (22) with a recess <23) extending by a connection fillet with a smooth surface (24) of smaller section intended to come as an extension and end-to-end support on the pipe (T1) against which it is welded. The second element <3> constitutes a support flange for the cover (4>. This flange comprises a ring shape <4 '> intended to come opposite and support against the complementary part of the first element. This flange is arranged with a cavity to receive the axis <5> of articulation of the cover <4>, while a seal is arranged on the flange to come to self-center in the recess (23). , the flange 'has a threaded seat (3) in its rear part. The nut ring (6) fits onto the seat (3 => and directly or indirectly has a smooth outer seat (6') intended for come end to end with the second pipe <T2>. A seal (7) is arranged between the nut ring and the bearing surface <3 =>. The method according to the invention aims to secure the end of the first by welding element <2> by its smooth end-to-end bearing with the corresponding pipe (T1), to do the same between the associated bearing (6 ') to the ecru ring u (6) and the second means (T2), then to fix by bolting (8) or other connecting means the support flange of the cover on the first element <2) then to mount the nut ring on the threaded seat.

L'opérateur peut alors utiliser une clé de manoeuvre < > pour l'orientation désirée de l'opercule. On a représenté par les différentes flèches (F1) les opérations de soudage, par (F20 l'opération de rapprochement et de fixation du premier élément avec la bride support, et par (F3) le montage de la bague écrou. The operator can then use an operating key <> for the desired orientation of the cover. The various arrows (F1) represent the welding operations, by (F20 the operation of bringing together and fixing the first element with the support flange, and by (F3) the mounting of the nut ring.

On souligne les avantages de montage rapide selon l'invention, l'absence de détérioriation en particulier des joints absents du montage lors des opérations de soudure. The advantages of rapid assembly according to the invention, the absence of deterioration, in particular of the joints absent from the assembly during welding operations, are emphasized.

En outre, tels que réalisée et montée la vanne peut entre vendue en bottier d'emballage sous forme de kit de montage. In addition, as produced and assembled, the valve can be sold as a package in the form of an assembly kit.
