Abstract

The invention relates to a device for monitoring the flow of liquid in a pipe using electromagnetic means. The figure diagrammatically represents one of the means of implementing the invention, essentially comprising, in this example, a floating magnet 2 inserted in a pipe 1 made of non-conducting material, along which it can move freely between two constrictions (pinches) 3 and 4 associated with an electrical contactor controlled by magnetic action and located in the immediate vicinity of the pipe in order either to close or open an electric circuit as a function of the position of the magnet whose displacement results from the flow of the liquid in the direction of the arrow. Multiple combinations of these means may be designed depending on the application envisaged. The invention is advantageously applicable for controlling the filling of a WC flush tank (cistern), the starting of a WC grinder (disintegrator) at the moment when the toilet is flushed, etc.

Description

La presente invention a pour objet un dispositif permettant d'agir sur un circuit électrique en fonction d'une circulation de liquide, tel que de l'eau, dans une tuyauterie d'alimentation quelconque.The present invention relates to a device for acting on an electrical circuit according to a circulation of liquid, such as water, in any supply piping.

Elle comprend essentiellement un aimant mobile et tel que cylindrique, inséré dans un conduit pour par exemple produire un signal électrique dès l'ouverture d'un robinet et l'interrompre lors de la fermeture de ce dernier.It essentially comprises a movable magnet, such as a cylindrical one, inserted in a duct to, for example, produce an electrical signal as soon as a tap is opened and interrupt it when the tap is closed.

L'application de l'invention n'est pas bien entendu limitée à ce qui vient d'être indique.The application of the invention is not of course limited to what has just been indicated.

On decrira deux modes de realisation en se référant-au dessin annexé à titre non limitatif.Two embodiments will be described with reference to the drawing attached without limitation.

Les figures 1 et 2 representent sohematiquernent une fraction de tuyauterie pourvue des moyens d'action.Figures 1 and 2 show a schematic part of the piping provided with means of action.

La figure 3 represente, egalement de manière schematique,ane variante de realisation.Figure 3 shows, also schematically, an alternative embodiment.

La figure 4 en represente une variante de realisation avec l'application à une chasse d'eau de W.C.Figure 4 shows an alternative embodiment with the application to a toilet flush.

Sur la figure 1, la reference 1 de signe une partie de conduit en matériau non conducteur dans lequel a ete disposé un aimant 2 de diametre inférieur à celui du conduit. A chacune des extrémités de ce dernier ont ete pratiques respectivement un pincement non circulaire portant les références 3 et 4. De cette manière la course Dos- sible de l'aimant est limitee par ces pincements qui au contraire n'affectent pas la libre circulation du liquide. Les references
A, B, C de signent chacune un contacteur electrique commande par action magnetique. In FIG. 1, the reference 1 indicates a part of a conduit made of non-conductive material in which a magnet 2 has been placed, with a diameter smaller than that of the conduit. At each end of the latter, a non-circular pinching with the references 3 and 4 respectively has been practiced. In this way the visible stroke of the magnet is limited by these pinches which on the contrary do not affect the free circulation of the liquid. The references
A, B, C each sign an electrical contactor controlled by magnetic action.

Bien entendu on peut combiner ou non ces contacteurs. On comprend aisément qu'un contacteur A sera influencé par la position de l'aimant si ce dernier est à son voisinage sous la poussée provoquée par le liquide circulant dans la direction indiquee par la flèche et que cette influence cessera si l'aimant s'en éloigne par suite par suite d'une chute de pression ou évacuation. I1 en sera de même, mais inversement, si un contacteur est place en C. Si un contacteur est placé en B, il sera influencé au passage de l'aimant dans un sens et dans l'autre. I1 est évidemment préférable que la partie de conduit soit disposée verticalement.Of course, these contactors can be combined or not. It is easily understood that a contactor A will be influenced by the position of the magnet if the latter is in its vicinity under the thrust caused by the liquid flowing in the direction indicated by the arrow and that this influence will cease if the magnet s' away from it as a result of a pressure drop or evacuation. I1 will be the same, but vice versa, if a contactor is placed in C. If a contactor is placed in B, it will be influenced by the passage of the magnet in one direction and in the other. It is obviously preferable that the duct part is arranged vertically.

Suivant les apDlications on peut désirer pouvoir placer un contacteur en B mais que ce dernier ne soit influencé que dans un sens de mouvement de l'aimant. Dans ce cas, il est prévu one variante représente sur la figure 3Suivant laquelle la partie de conduit 1 est dédoublée pour former deux tronçons la et lb aux points de jonction 5a et 5b. Ces points de jonction sont formés de telle sorte que l'aimant puisse passer seulement par la branche la dans le sens de la flèche 6 et dans la branche lb dans le sens de la flèche 7. According to the apDlications one may wish to be able to place a contactor at B but that the latter is only influenced in one direction of movement of the magnet. In this case, provision is made for a variant shown in FIG. 3, which the duct part 1 is split to form two sections 1a and 1b at the junction points 5a and 5b. These junction points are formed in such a way that the magnet can only pass through the branch 1a in the direction of arrow 6 and in the branch 1b in the direction of arrow 7.

Ainsi, en disposant un contacteur à l'emplacement 8, ce contacteur sera influencé seulement lorsque l'aimant passera dans la branche la, mais si le contacteur est disposé à l'emplacement 9 il sera influencé seulement si l'aimant passe dans la branche lb.Thus, by having a contactor at location 8, this contactor will be influenced only when the magnet passes through the branch la, but if the contactor is disposed at location 9 it will be influenced only if the magnet passes through the branch lb.

Cette variante de réalisation permet toutes combinaisons de commutation et notamment de n'agir que pour un mouvement de liquide dans un seal sens prédéterminé si l'eplacement choisi est 8 ou 9.This alternative embodiment allows all switching combinations and in particular to act only for a movement of liquid in a seal predetermined direction if the chosen location is 8 or 9.

Suivant l'exemple représenté sur la figure 4, la référence 10 désigne un réservoir de chasse d'eau de,S. alimenté par une électrovanne il disposée sur le conduit d'arrivée d'eau 12 aboutissant dans le fond 13 du réservoir 1C. 'aimant 14 est disposé sur un flotteur 15. L'ensemble 14-15 est mobile dans un tube de guidage 16 placé dans le réservoir 10. Lorsque le niveau atteint une hauteur prédéterminée 18 le circuit électrique de l'électrovanne 11 est coupé par l'arrivée de l'aimant 14 en regard du contacteur inverseur magnétique 19. Un double siphon 20-22 est disposé dans le réservoir 10. I1 est connu comme étant un facteur de vidange ultra rapide et utilisé ici pour cette raison.According to the example shown in FIG. 4, the reference 10 designates a flushing tank of, S. powered by a solenoid valve it disposed on the water inlet pipe 12 terminating in the bottom 13 of the tank 1C. magnet 14 is arranged on a float 15. The assembly 14-15 is movable in a guide tube 16 placed in the reservoir 10. When the level reaches a predetermined height 18 the electrical circuit of the solenoid valve 11 is cut by the arrival of the magnet 14 opposite the magnetic reversing contactor 19. A double siphon 20-22 is disposed in the tank 10. I1 is known to be an ultra-fast emptying factor and is used here for this reason.

Un interrupteur-inverseur 21 est monté en va et vient sur le circuit de l'électrovanne il et du contacteur électro magnétique 19.A reversing switch 21 is mounted back and forth on the circuit of the solenoid valve 11 and of the electromagnetic contactor 19.

Lorsque lton commande la vidange du réservoir,on agit sur le circuit du contacteur à l'électrovanne pour l'ouvrir et pour fermer simultanément le circuit de l'interrupteur-inverseur 21 provoquant le remplissage du réservoir 10 jusqu'au sommet du siphon 22, I1 s'établit alors un siphonage rapide qui vide le réservoir en en'trombe et fait descendre l'aimant 14 et le flotteur 15 dans le fond 23 du tube 16.When the tank is emptied, action is taken on the circuit from the contactor to the solenoid valve to open it and to simultaneously close the circuit of the reversing switch 21 causing the filling of the tank 10 to the top of the siphon 22, I1 then establishes a rapid siphoning which empties the tank in overflow and brings down the magnet 14 and the float 15 into the bottom 23 of the tube 16.

Lorsque le réservoir se remplit, l'aimant et le flotteur remontent
Jusqu'à ce que le liquide atteigne le niveau requis prédéterminé 18.When the tank fills, the magnet and the float go up
Until the liquid reaches the predetermined required level 18.

A oe moment il en résulte que l'aimant flottant agit sur le contacteur inverseur magnétique 19 qui ouvre le circuit de l'électrovanne 11 interrompant l'alimentation en liquide.At this moment it follows that the floating magnet acts on the magnetic reversing contactor 19 which opens the circuit of the solenoid valve 11 interrupting the supply of liquid.

L'appareil est alors prêt pour un nouveau cycle de fonctionnement.The device is then ready for a new operating cycle.

Il est bien entendu que les exemples illustrés étant schématiques; toutes formes de réalisation pourront Qtre déterminées suivant l'application désirée.It is understood that the examples illustrated are schematic; all embodiments may be determined according to the desired application.

Suivant une autre disposition de l'invention non représentée ici, on peut disposer deux tubes de hauteur différente contenant un aimant magnétique flottant tel que décrit. L'un de ces tubes étant vidé par siphonage, la position de l'aimant magnétique flottant agit sur un contacteur électromagnétique disposé au voisinage de l'aimant, de manière à obtenir selon la position des contacteurs magnétiques une position de temporisation.According to another arrangement of the invention not shown here, it is possible to have two tubes of different height containing a floating magnetic magnet as described. One of these tubes being emptied by siphoning, the position of the floating magnetic magnet acts on an electromagnetic contactor disposed in the vicinity of the magnet, so as to obtain, according to the position of the magnetic contactors, a delay position.

On peut également appliquer les moyens de l'invention pour tout appareil utilisant un contact électrique à l'ouverture d'un circuit fluide tel que par exemple la mise en marche d'un broyeur de WC au moment où l'on tire la chasse d'eau. Le contact s'établira alors d'une façon plus fiable qu'avec un pressostat, à l'instant précis où le circuit d'eau sera ouvert et il suffira ensuite d'un dispositif de temporisation pour le rompre.  One can also apply the means of the invention for any device using an electrical contact at the opening of a fluid circuit such as for example the starting of a toilet crusher when the flush is flushed. 'water. The contact will then be established more reliably than with a pressure switch, at the precise moment when the water circuit will be open and it will then suffice with a time delay device to break it.
