Description
La présente invention a pour objet un dispositif de ventouse pour évacuerThe present invention relates to a suction cup device for evacuating
l'air des conduites d'eau sous pression, air from pressurized water pipes,
permettant notamment d'éviter les coups de bélier. allowing in particular to avoid water hammer.
On connaît déjà de nombreux dispositifs de ventouse, qui permettent l'expulsion de l'air sur une conduite sous pression et l'entrée de l'air lors de la vidange de ladite conduite. Ces dispositifs sont notamment destinés à équiper des réseaux d'eau potable ou d'eaux usées. De manière générale ces dispositifs comprennent une enceinte qui communique avec la conduite et qui est disposée en un point haut du circuit, et qui comporte, de préférence supérieurement, un orifice pour le passage de l'air, apte à être ou non, selon le cas envisagé, bouché par un Numerous suction cup devices are already known, which allow the expulsion of air on a pressurized pipe and the entry of air during the emptying of said pipe. These devices are in particular intended to equip drinking water or wastewater networks. In general, these devices comprise an enclosure which communicates with the pipe and which is arranged at a high point of the circuit, and which comprises, preferably superiorly, an orifice for the passage of air, capable of being or not, depending on the envisaged case, blocked by a
flotteur disposé à l'intérieur de ladite enceinte. float disposed inside said enclosure.
Dans le cas d'une surpression, le flotteur s'élève et est amené à fermer l'orifice supprimant ainsi tous risques de fuite, dans le cas de dépression le flotteur est éloigné de In the case of an overpressure, the float rises and is brought to close the orifice thus eliminating any risk of leakage, in the case of depression the float is moved away from
l'orifice ce qui autorise la rentrée d'air. the orifice which authorizes the return of air.
Les dispositifs existants présentent des inconvénients, notamment en ce que le flotteur est associé à des moyens de guidage complexes et fragiles, qui de plus en ralentissent le fonctionnement et sont donc préjudiciables à la fonction du dispositif. Par ailleurs, ces dispositifs sont sensibles au dépôt de calcaire et, dans le cas d'une utilisation sur un circuit d'eaux usées, aux détritus en suspension, en sorte qu'à la The existing devices have drawbacks, in particular in that the float is associated with complex and fragile guide means, which moreover slow the operation thereof and are therefore detrimental to the function of the device. Furthermore, these devices are sensitive to lime deposits and, in the case of use on a wastewater circuit, to suspended detritus, so that at the

En référence aux figures 1 et 2, on peut voir qu'un dispositif de ventouse selon l'invention comprend une enceinte 1 de forme tubulaire, bordée supérieurement par une partie tronconique 2 présentant une ouverture centrale 20 débouchant sur l'extérieur, et bordée inférieurement par une partie tronconique 3 présentant une ouverture centrale 30 débouchant With reference to FIGS. 1 and 2, it can be seen that a suction device according to the invention comprises an enclosure 1 of tubular shape, bordered above by a frustoconical part 2 having a central opening 20 opening onto the outside, and bordered below by a frustoconical part 3 having a central opening 30 opening
sur la conduite 4 d'un circuit d'eau. on line 4 of a water circuit.
L'ouverture 20 donne sur une partie tubulaire 21, tandis The opening 20 opens onto a tubular part 21, while
qu'un joint torique 5 est disposé et fixé dans cette dernière. that an O-ring 5 is disposed and fixed in the latter.
On notera qu'il peut être prévu un épaulement dans la partie It should be noted that a shoulder may be provided in the part
tubulaire 21 pour caler le joint torique 5. tubular 21 for wedging the O-ring 5.
La partie tronconique 3 comporte à proximité de l'ouverture 30 et faisant saillie de sa paroi interne des plots The frustoconical part 3 comprises near the opening 30 and projecting from its internal wall of the studs
31 répartis sur le tout pourtour.31 distributed all around.
L'enceinte tubulaire renferme un flotteur 6 de forme sphérique destiné, lors d'une montée en pression, à venir se plaquer contre le joint torique 5 sous la montée P de l'eau après évacuation de l'air, et ainsi obturer l'ouverture 20, The tubular enclosure contains a float 6 of spherical shape intended, during a rise in pressure, to come to be pressed against the O-ring 5 under the rise P of the water after evacuation of the air, and thus to close the opening 20,
comme cela est représenté sur la figure 1. as shown in Figure 1.
On notera l'emplacement du joint torique 5, qui est placé dans la partie tubulaire 21, afin que la paroi de la partie Note the location of the O-ring 5, which is placed in the tubular part 21, so that the wall of the part
tronconique 2 réalise jusqu'à son extrémité sa fonction d'autocentrage du flotteur 6. tapered 2 performs its self-centering function of the float 6 to its end.
Lorsque la pression chute, tel que cela est représenté sur la figure 2, le flotteur descend dans l'enceinte 1 jusqu'à venir reposer sur les plots 31 qui consistent en des espaceurs permettant de soutenir le flotteur 6 tout en autorisant le passage de l'air, matérialisé par une flèche double A, entre le circuit et l'extérieur. Cette configuration est notamment When the pressure drops, as shown in FIG. 2, the float descends into the enclosure 1 until it comes to rest on the studs 31 which consist of spacers making it possible to support the float 6 while allowing the passage of the air, materialized by a double A arrow, between the circuit and the outside. This configuration is notably
