Description
Dispositif de sécurité pour conduit flexible d'alimentation en eau pour appareils électro-ménagers. Safety device for flexible water supply duct for household appliances.
Il est destiné à assurer immédiatement et automatiquement, sans débordement l'arrêt de l'alimentation en cas de surpression ou autre. It is intended to immediately and automatically ensure, without overflow, that the supply stops in the event of overpressure or otherwise.
Il existe de multiples dispositifs de sécurité pour appareil ménager fonctionnant à l'eau mais utilisant des systèmes complexes de vannes magnétiques ou autres afin d'arrêter la distribution du fluide sous pression et assurer son évacuation en cas d'obturation ou autre. There are multiple safety devices for household appliances operating with water but using complex systems of magnetic valves or the like in order to stop the distribution of the fluid under pressure and ensure its evacuation in the event of a blockage or the like.
Le dispositif suivant l'invention supprime ces inconvénients et entre autre ceux découlant des entartrages ou risques d'électrocution, et permet par son intégration à l'entrée du tuyau d'alimentation reliant le réseau sous pression à l'appareil récepteur d'obturer automatiquement et d'une façon irréversible la sortie d'eau au branchement, tout en donnant l'avantage de présenter une seconde sécurité en assurant l'arrêt de l'écoulement dans le cas extrême ou le flexible se rompant, en même temps que la mise hors service de la double enveloppe. The device according to the invention eliminates these drawbacks and inter alia those arising from scaling or risk of electrocution, and allows, by its integration at the inlet of the supply pipe connecting the pressurized network to the receiving device, to automatically shut off and irreversibly the water outlet at the connection, while giving the advantage of presenting a second safety by ensuring the flow stop in the extreme case or the flexible hose breaking, at the same time as the setting out of service of the double envelope.
Il est constitué par la combinaison du circuit distributeur formé par la conduite débouchant dans la chambre d'admission comportant un siège de clapet relié au tuyau et flexible de l'appareil électro-ménager avec le circuit de sécurité formé par la double gaine communiquant avec la chambre de commande comportant une membrane élastique solidaire d'un piston et du clapet situé dans l'axe de la chambre et du siège de clapet. It consists of the combination of the distributor circuit formed by the pipe opening into the intake chamber comprising a valve seat connected to the hose and hose of the household appliance with the safety circuit formed by the double sheath communicating with the control chamber comprising an elastic membrane integral with a piston and the valve located in the axis of the chamber and the valve seat.
Sur les dessins annexés, donnés à titre d exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 est une vue en coupe et en élévation du dispositif dans son ensemble.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 is a sectional view in elevation of the device as a whole.
La figure 2 représente également vu en coupe et en élévation, mais à une échelle différente le détail constructif et fonctionnel du clapet obturateur. Figure 2 also shows in section and in elevation, but on a different scale the constructive and functional detail of the shutter valve.
Le corps 1 comporte un conduit 2 relié à la conduite 3 par un orifice 4 formant siège de clapet débouchant dans la chambre 5. The body 1 comprises a duct 2 connected to the duct 3 by an orifice 4 forming a valve seat opening into the chamber 5.
Son extrémité 6 est reliée au flexible 7 débouchnant dans l'appareil électro-ménager où peut se produire une surpression. Its end 6 is connected to the hose 7 opening into the household appliance where overpressure may occur.
Le corps 1 comporte un épaulement périphérique ö sur lequel se fixe l'enveloppe ou double gaine 9 cerclant le conduit excentré 10 débouchant dans la chambre 11. The body 1 has a peripheral shoulder ö on which the envelope or double sheath 9 is fixed, encircling the eccentric duct 10 opening into the chamber 11.
Dans l'axe de cette chambre 11 est disposé un palier 12 intégré au cloisonnement 13 formant monture fixe. In the axis of this chamber 11 is disposed a bearing 12 integrated into the partition 13 forming a fixed frame.
Ce palier supporte un clapet 14 situé dans l'axe du siège 4 et dont la tige coulissante 15 pourvue de joints toriques 16, 17 constitue un piston mobile dont le flasque de poussée est solidaire d'une garniture étanche 18 pourvue périphériquement d'un joint souple et élastique 19. This bearing supports a valve 14 located in the axis of the seat 4 and whose sliding rod 15 provided with O-rings 16, 17 constitutes a movable piston whose thrust flange is integral with a tight seal 18 provided peripherally with a seal flexible and elastic 19.
Ce piston et son flasque se déplacent dans la cage 20 pourvus d'un orifice 21 d'échappement d'air. This piston and its flange move in the cage 20 provided with an orifice 21 for air exhaust.
La monture rigide 13 est séparée du secteur de passage de fluide et étanchéisée par le joint 22. The rigid frame 13 is separated from the fluid passage sector and sealed by the seal 22.
On conçoit dès lors le fonctionnement de ce dispositif en marche normale le clapet 14, le piston 15 et la membrane 18 sont repoussés dans la cloche 11 par la pression du réseau. It is therefore conceivable the operation of this device in normal operation the valve 14, the piston 15 and the membrane 18 are pushed back into the bell 11 by the network pressure.
Par contre, si le flexible 7 éclate, l'eau au lieu de se répandre sur le sol avant toute intervention de l'usager, va se répandre dans l'espace 23 puis passer dans le conduit 10 et arriver dans la cloche 11. On the other hand, if the hose 7 bursts, the water instead of spreading on the ground before any intervention by the user, will spread in the space 23 then pass through the conduit 10 and arrive in the bell 11.
La membrane 18 subit la pression et par son secteur d'élasticité 19 agit sur le piston 15 qui fait plaquer le clapet 14 sur le siège 4. The membrane 18 is subjected to pressure and by its sector of elasticity 19 acts on the piston 15 which causes the valve 14 to be pressed against the seat 4.
L'arrivée d'eau est obturée et le risque d'inondation écarté. The water supply is blocked and the risk of flooding eliminated.
Dans le cas où l'enveloppe 9 viendrait à céder à son tour, la pression chute dans le flexible et dans la cloche 11. In the event that the casing 9 should fail in turn, the pressure drops in the hose and in the bell 11.
En cette occasion le clapet 14 reste plaqué sur son siège 4 par la pression d'un réseau d'adduction débouchant et retenu dans la chambre 5. On this occasion, the valve 14 remains pressed against its seat 4 by the pressure of a supply network emerging and retained in the chamber 5.
En tout état de cause, l'arrêt de l'eau est maintenu et les risques d'inondations supprimés partant d'un ensemble de moyens mécaniquement indéréglable et ne demandant aucun entretien particulier ni un apport d'énergie autre que celui du fluide distribué par le réseau. In any event, the stopping of the water is maintained and the risks of floods eliminated, starting from a set of mechanically foolproof means and requiring no particular maintenance or an energy supply other than that of the fluid distributed by the network.
Le joint torique 17, figure 2, a de multiples fonctions. The O-ring 17, Figure 2, has multiple functions.
Il empêche d'abord les salissures, les entartrages ou autres de pénétrer sur la paroi du cylindre 24.It first prevents dirt, scaling or the like from entering the wall of the cylinder 24.
Par son action, le joint 16 pourra coulisser librement lorsque le clapet fonctionnera. Il assure enfin par son diamètre l'étanchéisation totale de l'orifice 4 d'adduction d'eau à l'appa reil. By its action, the seal 16 can slide freely when the valve operates. Finally, by its diameter, it completely seals the orifice 4 for the supply of water to the device.
Enfin par son diamètre plus grand que celui du joint 16 il évite tout retour du piston dans -le cylindre. Finally by its diameter larger than that of the seal 16 it prevents any return of the piston in the cylinder.
Cette action de retenue est complétée par les ergots élastiques 26 solidaires du piston 25 qui s'écartent dès qu'ils sortent du cylindre 24 et empêchent tout retour du piston dans son logement et lui faisant conserver sa position d 'obturation de l'orifice 4. This retaining action is completed by the elastic lugs 26 integral with the piston 25 which move away as soon as they leave the cylinder 24 and prevent any return of the piston in its housing and making it retain its position for closing the orifice 4 .
Enfin l'orifice 21 d'échappement d'air comporte une tige 27 qui émerge sous l'effet de la poussée et constitue une signalisation visuelle qui peut éventuellement déclencher un dispositif d'alerte ou de coupure automatique d'arrivée d'eau. Le signal peut être commandé par la course du piston 25. Finally, the air exhaust orifice 21 comprises a rod 27 which emerges under the effect of the thrust and constitutes a visual signaling which can possibly trigger an alert device or automatic cutoff of water supply. The signal can be controlled by the stroke of the piston 25.
Ce fonctionnement est automatique et comporte une triple sécurité par le jeu des joints et ergots élastiques du piston au clapet obturateur suivant la figure 2. This operation is automatic and includes triple security by the play of the elastic seals and lugs of the piston to the shutter valve according to FIG. 2.
Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalent comme d'ailleurs les matières utilisées pour leur fabrication sans changer pour cela, la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture without changing for this, the general design of the invention which has just been described.
