Abstract

The fluid evacuation regulation is based on the movement of the fluid inside the regulating tank and not on its level inside the regulating tank. For example, in case of ram storm, the rising of the water level in the regulating tank controls the closing of the evacuation and the end of this rising stage, i.e. the end of the thunderstorm, controls the opening of the evacuation. In one version, the movement of the fluid moves a float which acts on a pulse emitting device which controls an electro-valve. Alternatively, the float directly controls the electro-valve.

Description

La présente invention concerne la commande de l'écoulement de liteau monte nue dans des réservoirs et plus spécialement dans les réservoirs régulateurs d'écoulement d'eau pluviale. The present invention relates to the control of the flow of strip mounted bare in tanks and more particularly in rainwater flow regulating tanks.

Dans les réalisations de ce genre les diamètres des orifices d'évacuation sont calculés pour que l'évacuation se prolonge pendant un temps assez long pour ne pas surcharger les collecteurs situés en Aval. In constructions of this kind, the diameters of the evacuation orifices are calculated so that the evacuation is prolonged for a time long enough not to overload the collectors located downstream.

Lorsque le collecteur Aval est saturé il est indispensable, en plus, que ltévacuation dans ce collecteur ne débute que lorsque la saturation commence à décroitre, en fait à partir d'un certain temps après la fin de l'orage. When the downstream collector is saturated, it is essential, moreover, that the evacuation in this collector does not begin until the saturation begins to decrease, in fact from a certain time after the end of the storm.

Le dispositif envisagé permet de fermer 1 1évacuation des réservoirs régulateurs pendant tout le temps de l'orage. The envisaged device makes it possible to close the drain on the regulating tanks during the entire storm.

La montée du niveau d'eau dans le réservoir régulateur commande la fermeture de l'évacuation et c'est l'art de cette montée de niveau qui provoque l'ouverture de l'évacuation. The rise in the water level in the regulating tank controls the closing of the evacuation and it is the art of this level rise that causes the opening of the evacuation.

C'est donc une commande basée sur un mouvement et non sur une hauteur déterminée de niveau. It is therefore a command based on a movement and not on a determined height of level.

Le dispositif comprend en fait deux dispositifs qui peuvent agir ensemble ou séparément. The device in fact comprises two devices which can act together or separately.

Le premier Fig. 1 est fondé sur une commande par impulsion d'une électrovanne Fig. A. Le deuxième est fondé sur une obturation d'évacuation commandée par le remplissage d'un réservoir primaire Fig. 2-i. Le premier comprend un flotteur qui monte B mesure que le niveau monte Fig. 1-B. The first Fig. 1 is based on a pulse control of a solenoid valve FIG. A. The second is based on an evacuation shutter controlled by filling a primary tank. 2-i. The first includes a float which rises B as the level rises. 1-B.

Ce flotteur anime, par un moyen mécanique quelconque, un appareil émetteur d'impulsion tel que dynamo. This float drives, by any mechanical means, a pulse-emitting device such as a dynamo.

Cette impulsion commande la fermeture d'une électro-vanne et l'évacuation est condamnée. This pulse controls the closing of a solenoid valve and the evacuation is condemned.

Qpand le niveau ne monte plus, il n'y a plus d'impulsion et les vannes sont ouvertes. When the level no longer goes up, there is no more impulse and the valves are open.

Le deuxième comprend un réservoir primaire qui se remplit dès que le premier volume d'eau s' écoule dans le régulateur Fig. 2-B. Il est de faible contenance et donc vite plein. A sa base se situe la surface d'obturation de l'orifice d'écoulement du régulateur qui est condamné dès le début de l'orage. The second includes a primary tank which fills as soon as the first volume of water flows into the regulator. 2-B. It is of small capacity and therefore quickly full. At its base is the shutter surface of the flow orifice of the regulator which is condemned from the start of the storm.

Un orifice très faible et indépendant évacue liteau de ce réservoir primaire Fig. 2-C. A very small and independent orifice discharges the batten from this primary reservoir Fig. 2-C.

L'orifice est calculé pour que l'évacuation de l'eau dure le temps nécessaire pour que la saturation du collecteur Aval aie cessé et donc pour que l'évacuation du réservoir régulateur puisse s'effectuer. The orifice is calculated so that the evacuation of the water lasts the time necessary for the saturation of the downstream collector to have ceased and therefore for the evacuation of the regulating tank to be carried out.

Dès que ce réservoir primaire est vide il devient flottant et en s'élevant dégage l'orifice d'évacuation du régulateur. As soon as this primary tank is empty, it becomes floating and, as it rises, clears the discharge port of the regulator.

Avec ces dispositifs ou l'un d'eux seulement, les vannes sont donc louver tes avec le retardement suffisant pour éviter 1 'évacuation tant que dure la saturation du collecteur Aval. With these devices or only one of them, the valves are therefore open with sufficient delay to avoid one evacuation as long as the saturation of the downstream collector lasts.

Cette disposition a l'avantage de commander fermeture et ouverture de l'évacuation quelle que soit l'importance de l'orage puisqu'elle est basée sur une notion de mouvement et non de hauteur de niveau. This arrangement has the advantage of controlling closure and opening of the evacuation whatever the importance of the storm since it is based on a notion of movement and not of level height.

Claims

RESBDDICATIONS

1 - fluid evacuation regulator according to claim 1 of the main patent, characterized in that it comprises a fluid evacuation regulator based on the movement of this fluid in the tank and which consists of a shut-off valve and limiting the evacuation rate.

2 - Regulator according to claim 1 characterized in that the movement of the fluid is captured by a float, as ben regarding the rise as the descent of the fluid level.

3 - Regulator according to claim 2 characterized in that the level movement by animating the float operates a device such as a dynamo, emitting a pulse which controls the closing of a tppe dlectro-valve valve (Fig. 1-A)

4 - Regulator according to claim 3 characterized in that the movement of the fluid level, can with a sufficiently large float directly produce the energy necessary for closing the solenoid valve instead of emitting a simple control pulse.

5 - Regulator according to claims 1 and 3 characterized in that a second device supplements or can replace the solenoid valve. The rise of the fluid fills a primary float tank (rice. 2-A) which, by increasing in weight due to its filling, causes the discharge opening of the regulating tank to be closed.

6 - Regulator according to claim 5 characterized in that this primary float tank is provided with an independent drain (Fig. 2-C) from that of the regulator tank (Fig. 2-A). As soon as the level rise stops, there is no more filling, the independent evacuation empties the primary float tank, it becomes float. As it rises in the fluid, it releases the evacuation of the regulating tank.
