Description

INSERT A DEBIT REGLABLE POUR FLEXIBLE SANITAIRE ADJUSTABLE FLOW INSERT FOR SANITARY FLEXIBLE
La présente invention a pour objet un insert dont l'orifice de passage de l'eau peut se régler, au gré de l'utilisateur, destiné à équiper les flexibles hydrauliques des installations sanitaires en particulier les flexibles utilisés pour raccorder les douchettes à la robinetterie d'arrivée d'eau.The present invention relates to an insert whose water passage orifice can be adjusted, at the discretion of the user, intended to equip the hydraulic hoses of sanitary installations in particular the hoses used to connect the showers to the taps water inlet.
L'intérêt d'un tel dispositif est de permettre à chaque utilisateur de calibrer facilement l'orifice du passage de l'eau dans le flexible afin de maîtriser la consommation qu'il juge utile, en fonction des conditions d'utilisation de l'installation.The advantage of such a device is to allow each user to easily calibrate the orifice of the passage of water in the hose in order to control the consumption which he deems useful, according to the conditions of use of the installation.
Différents dispositifs existent pour aboutir à cet objectif de maîtrise de la consommation d'eau, mais en règle générale : - il est nécessaire d'avoir un modèle spécifique pour s'adapter aux caractéristiques de l'un des raccords terminaux mâle ou femelle équipant le flexible, lors de la mise en place ou d'un démontage (pour échange par ex.), ce type de dispositif peut tomber ou se perdre, rendant caducs les résultats d'économies escomptés, il peut, comme nous l'exposerons plus loin, être positionné en sortie de flexible ce qui n'est pas l' optimum, enfin d'une manière générale, très peu sont réglables, sans avoir à procéder à l'échange du dispositif pour un modèle supérieur ou inférieur ou alors, le réglage n'est pas proportionnel à l'avancement du pas de vis du dispositif de réglage.Different devices exist to achieve this objective of controlling water consumption, but as a general rule: - it is necessary to have a specific model to adapt to the characteristics of one of the male or female end fittings equipping the flexible, during installation or disassembly (for exchange, for example), this type of device can fall or be lost, rendering the expected savings results obsolete, it can, as we will explain below , be positioned at the hose outlet which is not the optimum, finally in general, very few are adjustable, without having to exchange the device for a higher or lower model or else, the adjustment is not proportional to the advancement of the screw thread of the adjusting device.
Un flexible comporte habituellement à chacune de ses extrémités :A hose usually has at each of its ends:
- un écrou 1 de raccordement mâle ou femelle, un insert 2 se logeant à l'intérieur de l' écrou 1, un conduit d'eau 3, en matériau souple dans lequel s'enfonce à chacune de ses 2 extrémités l' insert 2, - une virole de sertissage 4 venant serrer le conduit 3 sur l' insert 2 afin d'assurer l'étanchéité de la liaison des éléments 2 et 3, enfin, et facultativement en fonction des caractéristiques mécaniques du conduit 3 (épaisseur, résistance à la pression...) , une gaine de protection 8 constituée soit par une spirale en feuillard métallique (laiton chromé habituellement) ou une tresse (fil inox ou nylon haute résistance) s' enroulant et protégeant le conduit 3, dans ce cas, la virole recouvre l'ensemble des éléments 3 et 4 pour les bloquer sur l' insert 2.- a nut 1 of male or female connection, an insert 2 being housed inside the nut 1, a water pipe 3, made of flexible material in which the insert 2 is inserted at each of its 2 ends , - a crimping ferrule 4 tightening the conduit 3 on the insert 2 in order to seal the connection of the elements 2 and 3, finally, and optionally depending on the mechanical characteristics of the conduit 3 (thickness, resistance to pressure, etc.), a protective sheath 8 constituted either by a metal strip spiral (usually chromed brass) or a braid (stainless or nylon wire high resistance) winding and protecting the conduit 3, in this case, the shell covers all of the elements 3 and 4 to block them on the insert 2.
Le dispositif proposé consiste à loger directement dans le trou central de passage d'eau existant à l'intérieur de l' insert 2, au moyen d'un filetage 7 pratiqué dans ce trou dans lequel vient se positionner une vis spécifique de réglage 13 au pas correspondant dudit trou. Cette vis comporte un trou intérieur longitudinal non débouchant, percée d'une pour plusieurs lumières radiales de passage d'eau, positionnées préférentielle ent côté zone non débouchante du trou intérieur, lesdites lumières communiquant avec ledit trou. II est alors possible au moyen d'un tournevis de visser ou dévisser la vis de réglage pour choisir l'ouverture nécessaire des lumières afin d'obtenir le débit désiré en sortie de flexible.The proposed device consists of being housed directly in the central hole for the passage of water existing inside the insert 2, by means of a thread 7 made in this hole in which a specific adjusting screw 13 is positioned at not corresponding of said hole. This screw has a non-opening longitudinal inner hole, pierced with one for several radial water passage openings, preferentially positioned on the non-opening zone side of the internal hole, said openings communicating with said hole. It is then possible by means of a screwdriver to screw or unscrew the adjusting screw to choose the necessary opening of the lights in order to obtain the desired flow rate at the hose outlet.
Il est recommandé de positionner cet insert au point de raccordement du robinet de commande afin d' éviter - lorsque l'on désire réduire le débit donc la consommation - d'engendrer des efforts de pression dynamiques non prévus sur la partie souple du flexible. Le matériau n'étant pas conçu pour subir en permanence de tels efforts en particulier pour les flexibles se raccordant aux douchettes. C'est également ce qui arrive lorsque les douchettes sont équipées d'un moyen permettant de réduire le débit d'eau. Les flexibles subissent alors cet effort non prévu, ce qui réduit leur durée d'utilisation en favorisant l'éclatement ou le dessertissage du conduit 3.It is recommended to position this insert at the connection point of the control valve in order to avoid - when it is desired to reduce the flow rate and therefore the consumption - to generate dynamic pressure forces not provided for on the flexible part of the hose. The material not being designed to undergo such efforts permanently, in particular for the hoses connecting to the showers. This is also what happens when the showers are equipped with a means to reduce the flow of water. The hoses then undergo this unexpected force, which reduces their duration of use by promoting the bursting or the disengagement of the conduit 3.
Sur le type de flexible destiné au raccordement des douchettes, il est très facile, compte-tenu des normalisations en vigueur, de déterminer où l' insert réglable doit être positionné. En effet, actuellement l'une des extrémités des flexibles comporte un écrou conique normalisé destiné à faciliter l'accrochage de la douchette sur son support. L' insert 2 doit donc être positionné à l'autre extrémité. Le flexible travaille alors dans des conditions normales sans subir aucun effort perturbant. Ce dispositif permet également de régler les problèmes occasionnés par les pressions trop élevées que l'on rencontre très souvent sur les réseaux d'alimentation - pression dépassant fréquemment 3 bars. De ce fait, les jets sont trop forts, piquants et désagréables.On the type of hose intended for the connection of the showers, it is very easy, taking into account the standards in force, to determine where the insert adjustable must be positioned. Indeed, currently one of the ends of the hoses comprises a standard conical nut intended to facilitate the attachment of the shower head to its support. The insert 2 must therefore be positioned at the other end. The hose then works under normal conditions without undergoing any disturbing force. This device also makes it possible to resolve the problems caused by the excessively high pressures which are very often encountered on supply networks - pressure frequently exceeding 3 bars. As a result, the jets are too strong, pungent and unpleasant.
A titre d'exemple, une forme d'exécution du dispositif proposé est décrite ci-après :By way of example, an embodiment of the proposed device is described below:
Fig.l et 2 sont une coupe longitudinale d'une extrémité du flexible à raccord femelle - fig.l et d'une extrémité mâle - fig.2 - ce flexible étant protégé par sa gaine 8.Fig.l and 2 are a longitudinal section of one end of the hose with female connector - fig.l and of a male end - fig.2 - this hose being protected by its sheath 8.
Fig.3 est une coupe longitudinale de l' insert complet 2. - Fig.4 celle d'une coupe de la vis de réglage 13.Fig.3 is a longitudinal section of the complete insert 2. - Fig.4 that of a section of the adjusting screw 13.
L' insert 2 comporte une collerette périphérique 5 se logeant à l'intérieur du raccord 1, l'emmanchement 6, cylindrique de préférence pénétrant à l'intérieur du conduit souple 3 comprend préférentiellement des formes de rétention « r » qui vont se combiner avec les caractéristiques de souplesse du matériau composant le conduit 3 afin d'améliorer le sertissage lors de la mise en place de la virole pour éviter que le conduit 3 ne se désolidarise de l' insert 2 lorsqu'il est soumis à un effort de traction selon T. Un filetage 7 est pratiqué à l'intérieur du trou central de passage d'eau 10, dans lequel viendra se visser la vis 13 décrite ci-après. Sur la collerette 5, un dégagement intérieur 9, à la périphérie du filetage 7 est pratiqué pour créer une zone d'arrivée d'eau spécifique vers les lumières 15 de la vis 13. Cette zone d'arrivée 9 est déterminée d'une part pour que sa surface d'entrée soit du moins égale à la surface de sortie d'eau du trou 17 et de la vis 13 et d'autre part pour avoir un écartement « e » permettant le passage des particules n'ayant pas une dimension supérieure à celles des lumières 15 afin d'éviter leur obturation. En complément, un léger épaulement externe 11 est pratiqué à la périphérie du dégagement 9 afin de favoriser le détournement de ces particules indésirables vers la zone de périphérie de la collerette. La vis 13 comporte un filetage 7 complémentaire de celui pratiqué dans l' insert 2. Le trou central longitudinal non débouchant 17, possède à sa partie supérieure les formes 14 nécessaires au vissage. Les lumières radiales 15, pratiquées préférentiellement du côté opposé à la zone de sortie d'eau du trou 17 débouchent dans ledit trou 17 afin de permettre le passage de l'eau. La somme des surfaces d'entrée des lumières 15 est au moins égale à celle de la surface de la section du trou 17. De plus, elles sont préférentiellement composées d'une forme semi-polygonale ou semi-circulaire dont la plus grande base 16 est parallèle au plan de la collerette, ceci afin d'obtenir une progression de leur ouverture de passage d'eau pratiquement proportionnelle à l'avancement du pas de vis 7. Ce qui n'est pas le cas si les lumières étaient par exemple circulaires. Afin de stopper la course de la vis 7 lorsque les lumières ont un degré d'ouverture minimale (par exemple fermeture totale des lumières ou simplement une ouverture correspondant à un débit minimum) , le filetage 7 pratiqué dans l' insert 2 s'arrête au point limite 12, tout vissage étant alors impossible. Par ailleurs, les tolérances de fabrication des filetages mâle/femelle 7 seront de préférence d'un type « serré » pour éviter que le réglage ne se modifie lors de vibrations parasites (coups de bélier par exemple) que peut subir l'installation. The insert 2 comprises a peripheral flange 5 housed inside the fitting 1, the fitting 6, preferably cylindrical penetrating inside the flexible duct 3 preferably comprises retention forms "r" which will combine with the flexibility characteristics of the material making up the conduit 3 in order to improve the crimping when the ferrule is put in place to prevent the conduit 3 from becoming detached from the insert 2 when it is subjected to a tensile force according to T. A thread 7 is made inside the central water passage hole 10, into which the screw 13 described below will be screwed. On the collar 5, an internal clearance 9, at the periphery of the thread 7 is made to create a specific water inlet zone towards the slots 15 of the screw 13. This inlet zone 9 is determined on the one hand so that its entry surface is at least equal to the water exit surface of the hole 17 and the screw 13 and on the other hand to have a spacing "e" allowing the passage of particles not having a dimension greater than those of the slots 15 in order to avoid their obturation. In addition, a slight external shoulder 11 is made at the periphery of the clearance 9 in order to promote the diversion of these undesirable particles towards the zone of the periphery of the collar. The screw 13 has a thread 7 complementary to that used in the insert 2. The non-opening longitudinal central hole 17 has at its upper part the shapes 14 necessary for screwing. The radial slots 15, preferably made on the side opposite the water outlet zone from the hole 17 open into the said hole 17 in order to allow the passage of the water. The sum of the inlet surfaces of the lights 15 is at least equal to that of the area of the section of the hole 17. In addition, they are preferably composed of a semi-polygonal or semi-circular shape, the largest base 16 is parallel to the plane of the collar, this in order to obtain a progression of their water passage opening practically proportional to the advancement of the screw thread 7. This is not the case if the lights were for example circular . In order to stop the travel of the screw 7 when the lights have a minimum degree of opening (for example total closing of the lights or simply an opening corresponding to a minimum flow), the thread 7 made in the insert 2 stops at limit point 12, all screwing then being impossible. Furthermore, the manufacturing tolerances of the male / female threads 7 will preferably be of a "tight" type to prevent the adjustment from being modified during parasitic vibrations (water hammer for example) that the installation may undergo.
