Abstract

The detection method uses a flow meter with magnetic contacts. When water flows either for use or because of a leak the contacts operate at a preset sensitivity and operate a timer relay (4). The timer relay activates two timing units (5,6). The first unit (5) prevents premature water valve (7) closure and the second (6) defines the time beyond which the water valve should close. Two further relays (8,9) close the water valve and maintain it closed as well as illuminating a visual alarm (11). The system may be reset by a contact (10).

Description

DESCRIPTION
La présente invention concerne un dispositif révélant la présence d'une ou plusieurs fuite(s) d'eau sur une installation domestique ou industrielle.DESCRIPTION
The present invention relates to a device revealing the presence of one or more water leaks in a domestic or industrial installation.

La connaissance d'une fuite d'eau (WC, chauffe--eau, canalisation éclatée,...etc.) sur une installation domestique ou industrielle oblige l'utilisateur à contrôler périodiquement sa consommation en eau indiquée par son compteur. Cette méthode implique un effk > rt répétitif et n'est pas fiable . Knowledge of a water leak (WC, water heater, exploded pipe, etc.) on a domestic or industrial installation obliges the user to periodically control his water consumption indicated by his meter. This method involves repetitive effk> rt and is not reliable.

Le dispositif selon l'invention permet de remédier à à cet inconvenient . n comporte en effet selon une première caractéristique, un débitmètre à flotteur à contact magnétique . Le contact magnétique placé sur l'une des valeurs de la plage de mesure du débitmètre permet de sélectionner un débit adéquat . L'utilisateur choisi un temps d'écoulement d'eau à l'aide d'une tempofisation . Quand le temps d'écoulement d'eau dépasse celui sélectionné à l'aide de la temporisation, une électrovanne placée en amont du débitmètre coupe l'alimentation générale en eau . L'utilisateur est ainsi alerté sur la présence d'une fuite sur son réseau ou sur une utilisation abusive en eau. Après vérfication de son réseau, l'utilisateur peut réarmer son installation . Lorsqu'il n'y a aucune consommation en eau, le système électrique de la présente invention est hors tension. The device according to the invention makes it possible to remedy this drawback. n indeed has, according to a first characteristic, a float flow meter with magnetic contact. The magnetic contact placed on one of the values of the measuring range of the flowmeter allows to select an adequate flow. The user chooses a water flow time using a tempofisation. When the water flow time exceeds that selected using the time delay, a solenoid valve placed upstream of the flow meter cuts off the general water supply. The user is thus alerted to the presence of a leak on his network or to excessive use of water. After verifying his network, the user can rearm his installation. When there is no water consumption, the electrical system of the present invention is switched off.

Selon des modes particuliers de réalisation:
- la plage de mesure du débitmètre peut avoir différentes amplitudes de débit
- tout type de débitmètre peut-être utilisé (débitmètre compact,...etc.)
- l'électrovanne peut-être placée en amont ou en aval du débitmètre
- les temporisations peuvent être mécaniques, et/ou électriques et/ou électroniques
et leurs plages horaires peuvent être variables
- I'alimentation électrique de la présente invention peut avoir différentes tensions
- le réarmement peut être réalisé à l'aide d'un boîtier électronique (commande à
distance...etc. ) et/ou manuel.According to particular embodiments:
- the measuring range of the flow meter can have different flow amplitudes
- any type of flowmeter can be used (compact flowmeter, ... etc.)
- the solenoid valve can be placed upstream or downstream of the flow meter
- the timers can be mechanical, and / or electrical and / or electronic
and their time slots can be variable
- the power supply of the present invention may have different voltages
- resetting can be carried out using an electronic unit (command to
distance ... etc. ) and / or manual.

-l'alarme peut-être sonore et/ou lumineuse
Les dessins annexés illustrent l'invention:
La figure 1 représente schématiquement le débitmètre, l'électrovarme, le compteur.-the alarm may be audible and / or bright
The accompanying drawings illustrate the invention:
Figure 1 shows schematically the flow meter, the solenoid valve, the meter.

La figure 2 représente le schéma électrique de la présente invention. Figure 2 shows the electrical diagram of the present invention.

En référence à ces dessins, lors d'un écoulement d'eau dû à un besoin de l'utilisateur ou à la présence d'une fuite, le flotteur (1) du débitmètre actionne le contact magnétique (2) placé sur l'une des valeurs de la plage de mesure (12) du débitmètre (3) . La valeur de débit sélectionnée doit-être fiable afin que le système électrique de la présente invention soit mis en tension dés le moindre passage en eau . Le contact magnétique (2) alimente en basse tension le relais (4) , lequel déclenche les temporisations (5) et (6) . La temporisation (5) pré-réglée permet d'éviter la fermeture prématurée de électrovanne (7).  With reference to these drawings, during a flow of water due to a need of the user or the presence of a leak, the float (1) of the flow meter actuates the magnetic contact (2) placed on one values of the measuring range (12) of the flow meter (3). The value of flow rate selected must be reliable so that the electrical system of the present invention is put under tension as soon as the slightest passage in water. The magnetic contact (2) supplies the relay (4) with low voltage, which triggers the timers (5) and (6). The pre-set time delay (5) avoids premature closing of the solenoid valve (7).

La temporisation (6) préalablement réglée par l'utilisateur détennine le temps d'écoulement en eau au-delà duquel l'électrovanne (7) se firme . Cette fermeture est assurée par les relais (8) et (9) . Le relais (8) déclenche la fermeture de l'électrovanne
(7) . Le relais (9) assure le maintien automatique de la fermeture de l'électrovanne (7) et
déclenche parallèlement l'alarme visuelle (11). Le contact (10) permet de réarmer
l'installation en provoquant la réouverture de l'électrovanne . Les temporisations se ré
initialisent automatiquement lorsque l'écoulement en eau cesse. The time delay (6) previously set by the user determines the water flow time beyond which the solenoid valve (7) is closed. This closure is ensured by relays (8) and (9). The relay (8) triggers the closing of the solenoid valve
(7). The relay (9) automatically maintains the closing of the solenoid valve (7) and
also triggers the visual alarm (11). The contact (10) allows to reset
the installation by reopening the solenoid valve. The timers re
initialize automatically when the water flow stops.

Le dispositif selon l'invention est particulièrement destiné à la révélation d'une ou
plusieurs fuite(s) d'eau sur une installation domestique ou industrielle. The device according to the invention is particularly intended for revealing one or more
several water leaks on a domestic or industrial installation.
