Description
La présente invention est relative à un dispositif permettant deThe present invention relates to a device for
commander, simultanément, l'ouverture des robinets d'une installation de simultaneously control the opening of the valves of a heating installation
distribution d'eau.water distribution.
Il est connu que dans une installation de distribution d'eau sanitaire les risques de développement de germes pathogènes, tels que ceux susceptibles de provoquer la légionellose, sont d'autant plus importants que l'eau stagne It is known that in a sanitary water distribution installation the risks of the development of pathogenic germs, such as those capable of causing legionellosis, are all the greater when water stagnates.
dans les canalisations.in the pipes.
C'est le cas, notamment, dans des locaux présentant de très nombreux This is the case, in particular, in premises with very many
points de puisage dont certains sont très peu utilisés. tapping points, some of which are very little used.
La solution pour prévenir ce risque de propagation consiste à rincer les canalisations ce qui conduit, à intervalles réguliers, à ouvrir tous les robinets d'une même installation pour que l'eau s'écoule pendant un temps prédéterminé. Cette solution est difficile à mettre en oeuvre lorsqu'il s'agit de robinets ordinaires, mais elle est quasi impossible pour de grandes installations du The solution to prevent this risk of spreading consists in rinsing the pipes which leads, at regular intervals, to open all the taps of the same installation so that the water flows for a predetermined time. This solution is difficult to implement in the case of ordinary taps, but it is almost impossible for large installations of the
genre de celles qu'on rencontre dans les hôpitaux par exemple. kind of those you find in hospitals for example.
En effet, ces installations utilisent des robinets, traditionnels ou temporisés, qu'il n'est pas possible d'ouvrir et de maintenir ouverts le temps nécessaire pour effectuer le rinçage qui nécessite, en général, plusieurs In fact, these installations use taps, traditional or timed, that it is not possible to open and keep open the time necessary to perform the rinsing which generally requires several
minutes.minutes.
Dans un robinet temporisé, de type connu, le clapet est appliqué contre son siège par la force exercée par la pression de l'eau contenue dans une chambre normalement obturée par un piston, ledit piston comportant un joint In a timed tap, of known type, the valve is applied against its seat by the force exerted by the pressure of the water contained in a chamber normally closed by a piston, said piston comprising a seal.
à lèvre et un trou calibré permettant à l'eau de pénétrer dans ladite chambre. lip and a calibrated hole allowing water to enter said chamber.
Pour ouvrir le robinet on repousse le piston en chassant l'eau contenue dans la chambre et qui s'échappe en franchissant le joint à lèvre ce qui a simultanément pour effet d'entraîner le soulèvement du clapet: l'eau s'écoule librement. Durant l'écoulement, une partie de l'eau pénètre dans la chambre par le trou calibré, repousse le piston et ramène le clapet contre son siège après un certain temps, ou temps de temporisation, qui dépend, entre autres, du volume de la chambre, de la section du trou calibré, voire de la To open the valve, the piston is pushed back by expelling the water contained in the chamber and which escapes by crossing the lip seal, which simultaneously has the effect of raising the valve: the water flows freely. During the flow, part of the water enters the chamber through the calibrated hole, pushes the piston and brings the valve back against its seat after a certain time, or time delay, which depends, among other things, on the volume of the chamber, of the calibrated hole section, or even of the
force d'un ressort interposé entre le fond de ladite chambre et ledit piston. force of a spring interposed between the bottom of said chamber and said piston.
Dans une installation, comportant de tels robinets, il est difficile de prévoir une personne à chaque robinet qui maintient le piston enfoncé et ce d'autant plus que la plupart des robinets comportent des dispositifs de sécurité qui empêchent l'interruption de la temporisation. En d'autres termes, même si l'utilisateur maintient le poussoir de commande enfoncé cette action est sans effet sur le temps de temporisation et à la fin de ce temps une nouvelle action sur le poussoir est nécessaire pour permettre l'écoulement de In an installation comprising such taps, it is difficult to provide a person for each tap which keeps the piston depressed, all the more so since most taps include safety devices which prevent the interruption of the time delay. In other words, even if the user keeps the control button pressed this action has no effect on the delay time and at the end of this time a new action on the push button is necessary to allow the flow of
l'eau.the water.
Certains robinets, tels que ceux utilisés dans les installations de douches comportent une commande dite à distance. En fait, la chambre de temporisation est reliée, par une canalisation, à un robinet auxiliaire de décharge comportant un clapet commandé par un poussoir qui permet de mettre ladite chambre à l'air libre et, par suite, de provoquer le soulèvement du clapet du robinet principal. Le problème reste le même: il n'est pas possible de maintenir un utilisateur devant chaque robinet auxiliaire de décharge, opération qui s'avérerait illusoire étant donné que ces robinets de décharge sont généralement pourvus d'un dispositif de sécurité qui empêche Some taps, such as those used in shower installations, have a so-called remote control. In fact, the delay chamber is connected, by a pipe, to an auxiliary discharge valve comprising a valve controlled by a pusher which makes it possible to put said chamber in the open air and, consequently, to cause the valve to be raised from the main tap. The problem remains the same: it is not possible to keep a user in front of each auxiliary relief valve, an operation which would prove illusory since these relief valves are generally provided with a safety device which prevents
l'utilisateur d'inhiber la durée de la temporisation. the user to inhibit the duration of the timer.
Le dispositif de l'invention est remarquable en ce que l'ensemble des robinets d'une installation est relié à une vanne auxiliaire permettant lorsque The device of the invention is remarkable in that all of the valves of an installation are connected to an auxiliary valve allowing when
celle-ci est ouverte de maintenir ouverts tous lesdits robinets de l'installation. the latter is open to keep all of said installation taps open.
Par l'expression " l'ensemble des robinets ", il faut entendre l'ensemble des robinets définissant une unité de gestion telle que l'ensemble des robinets de différents locaux ou l'ensemble des robinets de l'étage d'un By the expression "the set of taps" is meant the set of taps defining a management unit such as the set of taps from different premises or the set of taps on the floor of a
local par exemple.local for example.
Chaque chambre de temporisation est reliée par une canalisation Each delay chamber is connected by a pipe
appropriée à la vanne précitée.suitable for the aforementioned valve.
La présente invention sera mieux comprise par la description qui va The present invention will be better understood from the description which follows
suivre faite en se référant au dessin annexé à titre d'exemple indicatif, seulement, sur lequel: -la figure est une vue schématique, en coupe, montrant un robinet temporise d'un type connu; -la figure 2 est une vue analogue à la figure 1 montrant la mise en oeuvre du dispositif de l'invention; -la figure 3 est une vue à plus petite échelle montrant une installation follow made with reference to the attached drawing as an indicative example only, in which: the figure is a schematic view, in section, showing a timed tap of a known type; FIG 2 is a view similar to Figure 1 showing the implementation of the device of the invention; FIG. 3 is a view on a smaller scale showing an installation
conforme à l'invention.according to the invention.
En se reportant à la figure 1, on voit que de la façon connue, le robinet comporte un corps 1 présentant une entrée d'eau 2 et une sortie 3 séparé par un clapet 4 porté par une tige 5 présentant un piston 6, muni d'un joint à Referring to Figure 1, we see that in known manner, the valve comprises a body 1 having a water inlet 2 and an outlet 3 separated by a valve 4 carried by a rod 5 having a piston 6, provided with 'a joint to
lèvre connu, obturant une chambre 7. known lip, closing a chamber 7.
De la façon connue, le piston 6 communique avec la chambre 7 par As is known, the piston 6 communicates with the chamber 7 by
l'entremise d'un orifice calibré 8. through a calibrated orifice 8.
En enfonçant la tige 5, on soulève le clapet et on repousse le piston 6, By pushing in the rod 5, the valve is raised and the piston 6 is pushed back,
l'eau contenue dans la chambre s'échappant par la périphérie dudit piston. the water contained in the chamber escaping through the periphery of said piston.
L'eau pénètre alors dans la chambre 7 en empruntant l'orifice et repousse le piston jusqu'au moment o le clapet est de nouveau appliqué contre son siège et est maintenu par la pression de l'eau à l'intérieur de ladite chambre cette action est renforcée par un ressort, non représenté, interposé The water then enters the chamber 7 via the orifice and pushes the piston until the valve is again applied against its seat and is maintained by the pressure of the water inside said chamber this action is reinforced by a spring, not shown, interposed
entre le piston et le fond de la chambre. between the piston and the bottom of the chamber.
Selon l'invention, la chambre 7 est connectée, par une canalisation 9, According to the invention, the chamber 7 is connected, by a pipe 9,
ou canalisation de décharge, à une vanne 10. or discharge line, to a valve 10.
Si on ouvre la vanne 10 la pression dans la chambre 7 chute et le clapet du robinet se soulève. Si après un certain temps (celui nécessaire pour effectuer le rinçage) on referme la vannelO, le robinet effectue sa If the valve 10 is opened, the pressure in the chamber 7 drops and the valve flap rises. If after a certain time (the time necessary to perform the rinsing) the vannelO is closed, the tap performs its
temporisation et se referme.timeout and closes.
Il est à noter que, lorsque la vanne 10 est ouverte, l'eau de rinçage It should be noted that, when the valve 10 is open, the rinsing water
traverse l'orifice calibré 8 et effectue, aussi, le rinçage de la canalisation 9. crosses the calibrated orifice 8 and also rinses the pipe 9.
A la sortie de chaque robinet, un clapet anti-retour 11 est interposé sur la canalisation de décharge 9 pour s'opposer à la circulation de l'eau dans le sens vanne robinet. En effet, en l'absence de clapet anti-retour, l'ouverture normale d'un robinet entraînerait l'ouverture de tous les robinets connectés ensemble. La commande de la vanne 10 peut être manuelle ou asservie par une At the outlet of each tap, a non-return valve 11 is interposed on the discharge pipe 9 to oppose the circulation of water in the tap valve direction. Indeed, in the absence of a non-return valve, the normal opening of a tap would open all the taps connected together. The control of the valve 10 can be manual or controlled by a
horloge programmable ou par tout système électronique de programmation. programmable clock or by any electronic programming system.
Selon une variante, on peut concevoir que chaque robinet soit associé à une vanne de décharge commandée à distance à partir d'un poste de commande utilisant une liaison filaire dédiée, une liaison filaire par courant porteur, ou le réseau téléphonique, ou commandée par un signal radio reçu et According to a variant, it is conceivable that each tap is associated with a discharge valve controlled remotely from a control station using a dedicated wired link, a wired link by carrier current, or the telephone network, or controlled by a radio signal received and
traité par une interface adéquate. processed by a suitable interface.
