La présente invention est un dispositif pour stopper les fuites de gaz domestique (ouverture de robinet de gazinière, de chauffe eau à gaz, rupture de conduit etc...) et avertir l'utilisateur de l'existence d'une fuite.GAS -SYSMmFOfl: t
DESCRIPTION
The present invention is a device for stopping leaks of domestic gas (opening of a gas tap, gas water heater, broken pipe, etc.) and warning the user of the existence of a leak.
Aucun système ne permet de stopper les fuites et d'avertir l'utilisateur de l'existence d'une fuite. No system can stop leaks and warn the user of the existence of a leak.
Le dispositif selon l'invention, ses différents modes de fabrications et d'applications permet de paiier ces deux inconvénients
Les déssins annexés illustrent le dispositif:
- la figure 1 représente le dispositif selon une première confi giration. The device according to the invention, its different manufacturing methods and applications makes it possible to pay for these two drawbacks
The annexed drawings illustrate the device:
- Figure 1 shows the device according to a first configuration.
- la figure 2 représente le dispositif selon un mode particulier de
fabrication.- Figure 2 shows the device according to a particular mode of
manufacturing.
- la figure 3 représente le dispositif selon un mode particulier de
fabrication et d'application.- Figure 3 shows the device according to a particular mode of
manufacturing and application.
- la figure 4 représente le dispositif résultant de la combinaison des
dispositifs des figures 1 et 2.- Figure 4 shows the device resulting from the combination of
devices of Figures 1 and 2.
II comporte en effet selon une première caractéristique fig 1 une unité centrale dordinateur(l) pré programmé pourvue d'un bouton de commande. L'unité (1) est aussi connecté à :un capteur (4) permettant de mesurer le débit ou la vitesse du gaz, plusieurs thermomètres (6), une centrale d'alarme (7) et un petit moteur électrique(8) . According to a first characteristic, FIG. 1 comprises a central computer unit (l) preprogrammed provided with a control button. The unit (1) is also connected to: a sensor (4) for measuring the gas flow or speed, several thermometers (6), an alarm center (7) and a small electric motor (8).
II comporte aussi un boîtier( 2) étanche relié à l'arrivé du gaz (3). It also includes a sealed housing (2) connected to the gas inlet (3).
Le capteur de débit(4) ainsi qu'une soupape(5) sont placé à l'intérieur du
boîtier( 2) . La soupape(5) peut être actionnée par le moteur électrique (8) grâce à un bras 9). The flow sensor (4) and a valve (5) are placed inside the
housing (2). The valve (5) can be actuated by the electric motor (8) thanks to an arm 9).
Lorsque le gaz circule à travers le boîtier( 2) vers la gazinière ou le chauffe eau le capteur (4) mesure le débit du gaz et transmet l'information à l'unité centrale (1). Au même moment les thermomètres (6) placé à proximité des feux transmettent la température au voisinage de chaque brûleur
Au débit correspond une température ou somme de températures minimales (programme de l'unité centrale) si celles-ci venaient à ne pas correspondre au dit débit, il y aurait donc fuite. L unité centrale(1) après quelque secondes va alors commandé le déclenchement de l'alarme ( 7) et
la mise en marche du moteur (8) qui va actionner la fermeture de la soupape ( 5) et obstruer ainsi le passage du gaz dans le boîtier( 2).When the gas flows through the housing (2) to the gas stove or the water heater, the sensor (4) measures the gas flow and transmits the information to the central unit (1). At the same time the thermometers (6) placed near the lights transmit the temperature in the vicinity of each burner
The flow corresponds to a minimum temperature or sum of temperatures (central unit program) if these did not correspond to said flow, there would therefore be a leak. The central unit (1) after a few seconds will then command the triggering of the alarm (7) and
starting the engine (8) which will actuate the closing of the valve (5) and thus obstruct the passage of gas in the housing (2).
Pour ré initialiser le système il suffira d'appuyer sur le bouton de commande de l'unité centrale(l). To reset the system, simply press the control button on the central unit (l).
Selon un mode particulier de fabrication Fig 2 le capteur de débit (4) de la Fig 1 peut être supprimé et des capteurs ( 10 potentiomètre) peuvent être placé directement sur les boutons de commandes de chaque brûleur et connecté à l'unité (i) qui peut ainsi mesurer le degré d'ouverture des brûleurs. According to a particular manufacturing method Fig 2 the flow sensor (4) of Fig 1 can be deleted and sensors (10 potentiometer) can be placed directly on the control buttons of each burner and connected to the unit (i) which can thus measure the degree of opening of the burners.
Lorsqu'un capteur (10) informe de l'ouverture d'un brûleur, l'unité centrale (i) analyse la température du thermomètre correspondant. En cas d'abs- cence de température correspondante comme dans le 1 er cas (fig 1) l'unité centrale (i) va commander, après quelques secondes, le déclenchement de l'alarme( 7) et la mise en marche du moteur ( 8) pour actionner la soupape( 5) et obstruer le passage du gaz dans le boîtier (2). When a sensor (10) informs of the opening of a burner, the central unit (i) analyzes the temperature of the corresponding thermometer. If there is no corresponding temperature as in the first case (fig 1) the central unit (i) will command, after a few seconds, the triggering of the alarm (7) and the starting of the engine (8) to actuate the valve (5) and obstruct the passage of gas in the housing (2).
Selon une variante:
-Un dispositif peut résulté de la combinaison des dispositifs des Fig 1 et 2. Ce troisième dispositif serait muni d'un capteur de débit (4) fig 1 et des capteurs permettant de mesurer le degré d'ouverture des brûleurs fig 2. According to a variant:
-A device can result from the combination of the devices of Fig 1 and 2. This third device would be provided with a flow sensor (4) fig 1 and sensors for measuring the degree of opening of the burners fig 2.
Selon un mode particulier de fabrication et d'application:
-Un autre capteur (4.1) fig 3 pourra être placé à la sortie du conduit de gaz et connecté à I' unité centrale (1) qui pourra comparer le débit entre l'arrivée et la sortie du gaz. Une éventuelle variation du débit pourrait alors être détecté entre les capteurs ( 4.) et (4.1). Si cette variation s'avérait négative, il y aurait donc une fuite du conduit entre les capteur (4) et (4.1), l'unité centrale ( 1) va alors, commander le déclenchement de l'alarme ( 7) et la mise en marche du moteur (8) pour obstruer le passage du gaz dans le boîtier (2) grâce à la soupape ( 5). Il est à noter que cet utilisation peut se faire, lorsqu'il s'agit juste de la surveillance du conduit, sons l'utilisation de thermomètres ( 6 ) ou de
capteur du type potentiornètre ( 10
II est à noter qu'il sera préférable, de placer l'unité (1) et la centrale alarme ( 7 ) le plus loin possible des feux, de renforcer les câbles conducteurs aux abords des feux. According to a particular mode of manufacture and application:
-Another sensor (4.1) fig 3 could be placed at the outlet of the gas pipe and connected to the central unit (1) which could compare the flow between the arrival and the outlet of the gas. A possible variation in the flow rate could then be detected between the sensors (4.) and (4.1). If this variation turns out to be negative, there would therefore be a leak in the conduit between the sensors (4) and (4.1), the central unit (1) will then order the triggering of the alarm (7) and the setting when the engine is running (8) to obstruct the passage of gas in the housing (2) thanks to the valve (5). It should be noted that this use can be done, when it is just a question of monitoring the duct, such as the use of thermometers (6) or
potentiometer type sensor (10
It should be noted that it will be preferable to place the unit (1) and the alarm center (7) as far as possible from the lights, to reinforce the conductive cables around the lights.
