Abstract

The invention relates to a cock with a rotating spherical spool 1. d e of the two annular seals 6 and 7 serves as a support for the base 20 of a non-return valve 18. Tightening takes place by screwing the element 9 of the body in the element 8. Application: one-part cock of small size with built-in non-return valve.

Description

La présente invention est relative à une vanne distributrice à boisseau tournant, du genre de celles qu'on intercale sur une canalisation pour ouvrir ou fermer un passage permettant la circulation d'un liquide ou d'un gaz. Elle concerne plus particulièrement une vanne à boisseau tournant sphérique, c'est -à-dire dont l'ouverture et la fermeture s'effectuent par simple rotation du boisseau suivant une amplitude angulaire d' un quart de tour. The present invention relates to a distributing valve with a rotating plug, of the kind that is inserted on a pipe to open or close a passage allowing the circulation of a liquid or a gas. It relates more particularly to a spherical rotary plug valve, that is to say the opening and closing of which is effected by simple rotation of the plug according to an angular amplitude of a quarter turn.

Il est connu d'intercaler une vanne à boisseau sphérique sur une canalisation, notamment à proximité d'un compteur d'eau potable. Dans ce cas,outre la vanne distributrice, il est nécessaire de placer aussi sur la canalisation un clapet anti-retour afin d'interdir tnut éventuel retour d'eau polluée dans le circuit d'eau potable. Pour cela, l'encombre- ment du clapet anti-retour s'ajoute à celui de la vanne distributrice, d'autant plus qu'entre les deux doit rester disponible une certaine longueur de canalisation. En définitive, 1' installation de l'ensemble utilise beaucoup de main d'oeuvre et oblige à un encombrement important, pas toujours compatible avec l'espace dont dispose l'installateur. It is known to insert a ball valve on a pipe, especially near a drinking water meter. In this case, in addition to the distributor valve, it is also necessary to place a non-return valve on the pipe in order to prevent any possible return of polluted water to the drinking water circuit. For this, the size of the non-return valve is added to that of the distribution valve, all the more so since between the two must remain available a certain length of pipe. Ultimately, one installation of the assembly uses a lot of manpower and requires a large footprint, not always compatible with the space available to the installer.

La présente invention a pour but d'éviter ces inconvénients en réalisant sous une forme monobloc à encombrement minimum, une vanne distributrice à l'intérieur de laquelle est directement intégré un clapet anti-retour. The object of the present invention is to avoid these drawbacks by producing, in a one-piece form with minimum overall dimensions, a dispensing valve inside which a non-return valve is directly integrated.

Une vanne distributrice à boisseau sphérique selon l'invention comporte un corps dont l'arrivée et le refoulement sont situés en amont et en aval d'un boisseau rotatif sphérique à perforation transversale par rapport à l'axe de rotation, ce boisseau étant serré entre deux sièges annulaires, et elle est carctérisée en ce que l'arrière d'un de ces sièges annulaires serte son tour d'appui au socle d'un clapet anti-retour , lequel socle est bridé par un épaulement du corps de la vanne. A ball valve distribution valve according to the invention comprises a body whose inlet and outlet are located upstream and downstream of a ball valve with transverse perforation relative to the axis of rotation, this valve being clamped between two annular seats, and it is characterized in that the rear of one of these annular seats clamps its support turn to the base of a non-return valve, which base is clamped by a shoulder of the valve body.

En pratique, on constate que l'invention permet de réaliser cet ensemble monobloc sous un encombrement en longueur pratiquement égal à celui d'une vanne connue, ne comportant pas le clapet anti-retour. In practice, it can be seen that the invention makes it possible to produce this monobloc assembly in a space requirement in length practically equal to that of a known valve, not comprising the non-return valve.

Le dessin annexé, donné à titre d'exemple non limitatif, permet de mieux comprendre l'invention et les avantages qu'elle est susceptible de procurer. The appended drawing, given by way of nonlimiting example, allows a better understanding of the invention and the advantages which it is likely to provide.

Figure 1 est une coupe axiale d'une vanne distributrice selon l'invention lorsqu'elle est assemblée" prête à servir, le boisseau étant ouvert. Figure 1 is an axial section of a dispensing valve according to the invention when assembled "ready to serve, the plug being open.

Figure 2 est une coupe analogue avec le boisseau fermé. Figure 2 is a similar section with the plug closed.

Figure 3 est une vue éclatée montrant les éléments constitutifs de la vanne. Figure 3 is an exploded view showing the components of the valve.

La vanne distributrice montrée sur les dessins comprend un boisseau sphérique 1 qu'une poignée 2 permet de faire tourner autour d'un axe géométrique 3. Le boisseau 1 est traversé par une perforation tranversale 4 dont l'axe géométrique 5 est perpendiculaire à l'axe 3. The dispensing valve shown in the drawings comprises a ball valve 1 which a handle 2 allows to rotate around a geometric axis 3. The valve 1 is crossed by a transverse perforation 4 whose geometric axis 5 is perpendicular to the axis 3.

Le boisseau 1 est serré entre deux sièges annulaires d'étanchéité 6 et 7, dont l'axe colncide avec l'axe 5. The plug 1 is clamped between two annular sealing seats 6 and 7, the axis of which coincides with the axis 5.

L'ensemble est disposé entre les deux éléments 8 et 9 qui forment le corps de la vanne.The assembly is arranged between the two elements 8 and 9 which form the body of the valve.

L'élément amont 8 possède un embout de raccordement 10 pourvu d'un filetage extérieur 11 et qui définit le passage d'arrivée 12 à la vanne
L'élément aval 9 possède un embout lisse 13 pourvu à son extrémité une collerette 14 qui retient un écrou prisonnier 15 d'un type en lui-même connu pour raccorder la vanne à une canalisation aval non représentée. A l'intérieur, l ' em- bout 13 définit le passage de refoulement 16 de la vanne.The upstream element 8 has a connection nozzle 10 provided with an external thread 11 and which defines the inlet passage 12 to the valve
The downstream element 9 has a smooth end piece 13 provided at its end with a flange 14 which retains a captive nut 15 of a type in itself known for connecting the valve to a downstream pipe not shown. Inside, the end piece 13 defines the discharge passage 16 of the valve.

L'assemblage des deux éléments 8 et 9 s'effectue par vissage le long d'un filetage 17 centré sur l'axe géométrique 5. The two elements 8 and 9 are assembled by screwing along a thread 17 centered on the geometric axis 5.

Selon l'invention, on loge à l'intérieur de l'un des éléments 9 du corps, un clapet anti-retour 18 d'un type en lui-même connu. Ce clapet comporte un obturateur 19 mobile devant son siège qui est porté par un socle annulaire 20. According to the invention, there is housed inside one of the elements 9 of the body, a non-return valve 18 of a type known per se. This valve comprises a shutter 19 movable in front of its seat which is carried by an annular base 20.

Ici, le socle 20 prend appui directement contre le siège annulaire 7 qui lui correspond, et il y est repoussé par épaulement 21 prévu à l'intérieur de l'élément 9.Here, the base 20 bears directly against the annular seat 7 which corresponds to it, and it is pushed back there by shoulder 21 provided inside the element 9.

Le- fonctionnement est le suivant
A l'assemblage, il suffit, après mise en place des divers organes, de visser l'un dans l'autre (filetage 17) les deux éléments 8 et 9 pour serrer entre eux - à la fois les deux sièges dçétanchéité 6 et 7 du boisseau 1; - et le socle 20 du clapet anti-retour 18 qui est désormais
fixé en place de façon étanche.The operation is as follows
During assembly, it suffices, after fitting the various members, to screw one into the other (thread 17) the two elements 8 and 9 to clamp them - both the two sealing seats 6 and 7 bushel 1; - and the base 20 of the non-return valve 18 which is now
tightly fixed in place.

On comprend que la structure de cet ensemble monobloc permet d'économiser du temps de main d'oeuvre (donc de réduire les couts) aussi bien pour la fabrication que pour 1' installation de la vanne sur un réseau. It is understood that the structure of this monobloc assembly makes it possible to save labor time (therefore to reduce costs) both for the manufacture and for the installation of the valve on a network.

Par ailleurs, l'encombrement en longueur 22 de la vanne reste pratiquement le même que celui d'une vanne connue, c'est-à-dire ne comportant pas de clapet 18 incorporé. En particulier, cet encombrement n'est pas augmenté de la longueur 23 du clapet 18. Cet avantage résulte en particulier de la structure de l'élément 9 qui permet de disposer le clapet 18 essentiellement à l'intérieur de l'embout 13 dont la longueur reste de toute façon nécessaire au débattement longitudinal de l'écrou prisonnier 15.  Furthermore, the overall length 22 of the valve remains practically the same as that of a known valve, that is to say having no valve 18 incorporated. In particular, this space is not increased by the length 23 of the valve 18. This advantage results in particular from the structure of the element 9 which makes it possible to arrange the valve 18 essentially inside the end piece 13, the length remains anyway necessary for the longitudinal movement of the captive nut 15.
