Abstract

The subject of the invention is a differential pressure switch with magnetic data transmission. It is constituted by the combination of an electrovalve 4 with a control achieved by the magnetic repulsion of two magnets 11, 14 placed in two separate chambers 6, 13. It is intended to be used as a safety device for explosive hydrocarbons, such as liquid petroleum gases, in order to collect flow rate data during the filling of receiving volumes.

Description

L 'objet de l'invention concerne un mano-contact différentiel à transmission magnétique d'information. The object of the invention relates to a differential pressure switch with magnetic information transmission.

II est destiné à une utilisation de sécurité pour hydrocarbures détonnants, tels les gaz de pétrole liquide afin de permettre une prise d'information de débit lors des remplissages des capacités réceptrice. It is intended for safety use for explosive hydrocarbons, such as liquid petroleum gases in order to allow flow information to be taken when filling the receiving capacities.

Jusqu'à ce jour, l'information de débit pour la distribution d'un fluide liquide ou gazeux comportait des montages complexes et peu fiables découlant de l'obligation de supprimer toutes transmissions précises susceptibles d'être en contact direct avec le fluide explosif et de provoquer une étincelle. Until now, the flow information for the distribution of a liquid or gaseous fluid has involved complex and unreliable assemblies arising from the obligation to suppress all precise transmissions likely to be in direct contact with the explosive fluid and to cause a spark.

Le dispositif suivant l'invention supprime ces inconvénients et permet avec une sécurité totale, la transmission de l'information d'un débit par utilisation de la pression différentielle établie entre deux points du circuit en utilisant la perte de charge. The device according to the invention eliminates these drawbacks and allows, with total security, the transmission of information of a flow rate by using the differential pressure established between two points of the circuit by using the pressure drop.

ll est constitué par la combinaison d'une électro vanne avec une commande réalisée par répulsion magnétique de deux aimants placés dans deux chambres séparées,. It consists of the combination of an electro-valve with a control carried out by magnetic repulsion of two magnets placed in two separate chambers.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
Le mano-contact est constitué par un conduit 1, avec admission 2, et évacuation 3 dont le débit est commandé par une électro-vanne 4.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
The pressure switch consists of a duct 1, with inlet 2, and outlet 3, the flow of which is controlled by an electro-valve 4.

Le conduit est relié en amont par une canalisation 5 à une chambre étanche 6 en matière non magnétique 7, dont l'extrémité 8 est reliée par le conduit 9 en aval 10 de la canalisation 1. The pipe is connected upstream by a pipe 5 to a sealed chamber 6 made of non-magnetic material 7, the end 8 of which is connected by the pipe 9 downstream 10 from the pipe 1.

La chambre étanche 6 noyée dans le fluide contient une masse aimantée mobile 11, dont le pôle N est situé à sa partie antérieure 11'.  The sealed chamber 6 embedded in the fluid contains a mobile magnetic mass 11, the pole N of which is located at its front part 11 '.

La chambre 6 est obturée par une cloison 12 qui la sépare d'une façon étanche de la chambre 13 intégralement isolée de tout contact avec le fluide inflammable et détonant. The chamber 6 is closed by a partition 12 which separates it in a sealed manner from the chamber 13 completely isolated from any contact with the flammable and detonating fluid.

Cette chambre contient la masse aimantée mobile 14 dont le pôle N est situé à la partie postérieure 15. This chamber contains the mobile magnetic mass 14 whose pole N is located at the rear part 15.

La chambre 13 est obturée par un interrupteur à contact 16 pourvu d'un contacteur à lames 17 qui ouvre ou ferme le contact avec le circuit 18 actionnant 1 'électro-vanne 4 et le contrôleur de remplissage 19. The chamber 13 is closed by a contact switch 16 provided with a reed switch 17 which opens or closes the contact with the circuit 18 actuating the solenoid valve 4 and the filling controller 19.

Lorsque le fluide déplace l'aimant 11, son pôle N 12 se rapproche de l'aimant 14, dont le pôle N 15 repousse sa masse et lui fait contacter la lame 17 du contacteur 16. When the fluid displaces the magnet 11, its N pole 12 approaches the magnet 14, whose N pole 15 repels its mass and makes it contact the blade 17 of the contactor 16.

Par contre, lorsque 1' aimant sous l'effet de 1' écoule- ment du fluide ou de 1' arrêt d'écoulement se déplace, il commande l'ouverture ou la fermeture du circuit 18 qui ouvre ou ferme 1 'électro-vanne 4 arrêtant ou permettant 1 'écoulement du fluide. On the other hand, when the magnet under the effect of the flow of the fluid or of the flow stop moves, it controls the opening or closing of the circuit 18 which opens or closes the solenoid valve 4 stopping or allowing the flow of the fluid.

Les aimants sont montés aux distances voulues pour qu'ils se repoussent dès qu'ils se rapprochent et ce, à travers la paroi 12. The magnets are mounted at the desired distances so that they repel as soon as they approach and this, through the wall 12.

L ' information réalisée par répulsion magnétique de deux aimants de même pôle placés dans des capacités séparées et d'un fonctionnement sûr, parfaitement isolés et d'une très grande précision sans risque d' arrêt ou de transmission perturbable. The information produced by magnetic repulsion of two magnets of the same pole placed in separate capacities and of a safe operation, perfectly isolated and of a very high precision without risk of stopping or disturbable transmission.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d ' ailleurs les matières utilisées pour leur fabrication, sans changer pour- cela la conception générale de l'invention qui vient d'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, as indeed the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
