Description

Dispositif de réglage du débit d'un liquide dans une conduite,Device for adjusting the flow rate of a liquid in a pipe,

notament d'un liquide de refroidissement.  especially a coolant.

L'invention concerne le réglage du débit dans une  The invention relates to the adjustment of the flow rate in a

conduite d'un liquide, notamment d'un liquide de refroidissement.  conduct of a liquid, in particular a coolant.

On sait que, par exemple dans des installations de refroidissement de fils ou barres d'acier dans une gaine d'eau en circulation, la réussite du traitement, qui conduit à l'obtention des qualités requises pour le produit final, est conditionnée par  It is known that, for example in installations for cooling steel wires or bars in a circulating water sheath, the success of the treatment, which leads to obtaining the qualities required for the final product, is conditioned by

la maîtrise rigoureuse des paramètres de refroidissement.  rigorous control of cooling parameters.

Dans les installations connues à ce Jour, on règle généralement le débit dans la conduite principale par une vanne motorisée dont le degré d'ouverture réglable continûment définit la section de passage du fluide. Quand les paramètres sont stables ou évoluent lentement, ce mode de réglage donne satisfaction. Mais lorsqu'il est nécessaire de modifier brutalement les conditions de refroidissement, on constate un régime transitoire plus ou moins long selon le temps de réponse de la vanne motorisée, et une  In the installations known to this day, the flow rate in the main pipe is generally adjusted by a motorized valve, the continuously adjustable degree of opening of which defines the cross-section of the fluid. When the parameters are stable or change slowly, this setting mode is satisfactory. But when it is necessary to suddenly change the cooling conditions, there is a transient regime of varying length depending on the response time of the motorized valve, and a

précision finale défecteuse sur le débit obtenu.  defective final precision on the flow obtained.

Le but de l'invention est de proposer un système qui  The object of the invention is to propose a system which

pallie les inconvénients précités et propose un réglage ultra-  overcomes the aforementioned drawbacks and proposes an ultra-

rapide du débit qui ne se fasse pas au détriment de la précision.  fast flow which does not come at the expense of precision.

Selon l'invention, le dispositif de réglage du débit comporte, en dérivation sur ladite conduite principale, un ensemble de conduites calibrées montées en parallèle, chaque conduite calibrée étant pourvue d'une vanne en tout ou rien, et il  According to the invention, the device for adjusting the flow rate comprises, as a branch on said main pipe, a set of calibrated pipes mounted in parallel, each calibrated pipe being provided with an all-or-nothing valve, and it

est prévu des moyens de commande desdites vannes.  means for controlling said valves are provided.

Ainsi, grace au calibrage des conduites, calibrage que la technologie actuelle permet d'obtenir avec une excellente précision, le débit est réglé de façon extrêmement précise, par incréments dépendant des sections calibrées choisies. Les conduites calibrées, qui peuvent être identiques ou différentes, se prêtent à toutes les combinaisons de nombre et de section, qui sont nécessaires pour obtenir dans la conduite principale les  Thus, thanks to the calibration of the pipes, calibration that current technology makes it possible to obtain with excellent precision, the flow rate is adjusted in an extremely precise manner, in increments depending on the calibrated sections chosen. The calibrated pipes, which may be identical or different, lend themselves to all the combinations of number and section, which are necessary to obtain in the main pipe the

valeurs de débit utiles pour le traitement.  flow values useful for treatment.

L'utilisation de vannes en tout ou rien permet d'avoir  The use of all-or-nothing valves allows

un temps de réponse quasiment nul.almost zero response time.

Les moyens de commande sont de préférence un ordinateur de type microprocesseur qui commande l'obturation des vannes en fonction d'une valeur de débit affichée par l'opérateur ou  The control means are preferably a computer of microprocessor type which controls the closing of the valves as a function of a flow value displayed by the operator or

Avantageusement, les conduites calibrées sont des conduites de décharge, le liquide soustrait de la conduite  Advantageously, the calibrated pipes are discharge pipes, the liquid subtracted from the pipe

principale pouvant être recyclé.main can be recycled.

Avantageusement, les conduites calibrées sont prises sur une conduite de décharge collective piquée sur la conduite principale. Un tel dispositif s'-est avéré particulièrement satisfaisant à l'utilisation, en n'induisant dans la conduite  Advantageously, the calibrated pipes are taken from a collective discharge pipe stuck on the main pipe. Such a device has proven to be particularly satisfactory in use, by not inducing in the pipe.

principale aucune perturbation hydraulique notable.  main no significant hydraulic disturbance.

L'invention sera mieux comprise grâce à la description  The invention will be better understood thanks to the description

qui va suivre d'un mode particulier de réalisation donné à titre  which will follow from a particular embodiment given as

d'exemple non limitatif.non-limiting example.

Il sera fait référence à la figure unique annexée qui  Reference will be made to the attached single figure which

représente schématiquement le dispositif de l'invention.  schematically represents the device of the invention.

On y voit la conduite principale 1 destinée dans cet exemple de réalisation à alimenter une eau de refroidissement, par l'intermédiaire d'une chambre 2 de répartition à fente annulaire, un conduit 9, dans l'axe duquel défile une barre en acier 10 à refroidir, entourée par une enveloppe d'eau (non représentée) circulant dans le même sens - selon figure - ou dans un sens  We see the main pipe 1 intended in this embodiment to supply cooling water, via a distribution chamber 2 with annular slot, a duct 9, in the axis of which runs a steel bar 10 to be cooled, surrounded by an envelope of water (not shown) flowing in the same direction - as shown in the figure - or in one direction

opposé.opposite.

Conformément à l'invention, on a piqué sur la conduite principale 1 une conduite de décharge collective 3 sur laquelle sont dérivées des conduites calibrées parallèles 4 équipées chacune d'une électrovanne en "tout ou rien" 5. Les sorties des conduites calibrées 4 peuvent être regroupées dans un collecteur de retour 6 qui recycle l'eau dans le circuit de la conduite  In accordance with the invention, a collective discharge line 3 has been stuck on the main pipe 1 on which are derived parallel calibrated pipes 4 each equipped with an "all or nothing" solenoid valve 5. The outputs of the calibrated pipes 4 can be grouped in a return collector 6 which recycles water in the pipe circuit

principale 1.main 1.

Les vannes 5 sont commandées par un microprocesseur 7, qui peut également commander une vanne 8 d'arrêt général placée  The valves 5 are controlled by a microprocessor 7, which can also control a general stop valve 8 placed

sur la conduite 1.on driving 1.

6 5 7096 5 709

Le système peut fonctionner simplement de la manière suivante: la conduite d'alimentation 1 est dimensionnée de façon que, pour une pression d'entrée donnée de l'eau (généralement de 7 à 10 bars) assurant une vitesse suffisante à l'enveloppe d'eau dans le conduit de refroidissement 9, on obtienne dans ce dernier un débit maximal. Dans ces conditions, les électrovannes 5 sont donc normalement fermées. Le processeur 7 commande alors l'ouverture d'une vanne, ou de plusieurs, afin de réduire, d'une  The system can operate simply as follows: the supply line 1 is dimensioned so that, for a given inlet pressure of water (generally from 7 to 10 bars) ensuring sufficient speed for the envelope d water in the cooling duct 9, a maximum flow is obtained in the latter. Under these conditions, the solenoid valves 5 are therefore normally closed. The processor 7 then commands the opening of a valve, or of several, in order to reduce, by

quantité voulue, le débit d'eau dans le conduit 9.  desired quantity, the water flow rate in line 9.

En variante, on peut prévoir de laisser normalement les vannes 5 en position "ouverte" et commander dans ce cas leur fermeture lorsqu'on veut augmenter le débit d'eau de refroidissement. Bien entendu, entre ces deux variantes, toutes les options de fonctionnement intermédiaires sont parfaitement envisageables. Par ailleurs, le choix entre l'une ou l'autre de ces deux variantes pourra être fait en fonction du type de vannes dont on dispose (vannes "fermées" au repos ou "ouvertes" au repos), sachant que selon le type, c'est l'opération de fermeture ou celle d'ouverture respectivement qui est légèrement la plus rapide. Il va de soi que l'invention n'est pas limitée au refroidissement, ou au refroidissement de produits métalliques en défilement dans une gaine d'eau, mais étend son domaine d'application partout o l'on souhaite pouvoir modifier rapidement  As a variant, provision can be made to normally leave the valves 5 in the "open" position and, in this case, control their closing when the flow of cooling water is to be increased. Of course, between these two variants, all of the intermediate operating options are perfectly conceivable. Furthermore, the choice between one or the other of these two variants can be made according to the type of valves available (valves "closed" at rest or "open" at rest), knowing that depending on the type, it is the closing operation or the opening operation respectively which is slightly faster. It goes without saying that the invention is not limited to cooling, or to the cooling of metallic products running in a water sheath, but extends its field of application wherever it is desired to be able to modify rapidly.

et de manière précise le débit de fluides incompressibles.  and precisely the flow of incompressible fluids.
