DISPOSITIF DE REGLAGE DU DEBIT D'UN LIQUIDE DANS UNE CONDUITE, NOTAMMENT D'UN LIQUIDE DE REFROIDISSEMENT.DEVICE FOR ADJUSTING THE FLOW OF A LIQUID IN A PIPELINE, IN PARTICULAR OF A COOLING LIQUID.
L'invention concerne le réglage du débit dans une conduite d'un liquide, notamment d'un liquide de refroidissement.The invention relates to adjusting the flow rate in a pipe for a liquid, in particular a coolant.
5 On sait que, par exemple dans des installations de refroi dissement de fils ou barres d'acier dans une gaine d'eau en circulation, (USP 4 308 881 et USA 4 312 094) la réussite du traitement, qui conduit à l'obtention des qualités requises pour le produit final, est conditionnée per la maîtrise rigoureuse des paramètres 10 de refroidissement.5 It is known that, for example in installations for cooling steel wires or bars in a circulating water sheath, (USP 4 308 881 and USA 4 312 094) the success of the treatment, which leads to obtaining the qualities required for the final product, is conditioned by the rigorous control of the 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 15 lentement, ce mode de réglage donne satisfaction. Mais lorsqu’il est nécessaire de modifier brutalement les conditions de refroidissement r on constate un régime transitoire plus ou moins long selon le temps de réponse de la vanne motorisée, et une précision finale souvent défectueuse sur le débit obtenu.In the installations known to date, 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 evolve slowly, this mode of adjustment is satisfactory. But when it is necessary to suddenly change the cooling conditions r there is a transient regime of varying length depending on the response time of the motorized valve, and a final precision often defective on the flow obtained.
20 Le but de l'invention est de proposer un système qui pallie les inconvénients précités et propose un réglage ultra-rapide du débit qui ne se fasse pas au détriment de la précision.The object of the invention is to propose a system which overcomes the aforementioned drawbacks and proposes an ultra-rapid adjustment of the flow rate which is not done at the expense of precision.
Selon l'invention, le dispositif de réglage du débit comporte, en dérivation sur ladite conduite principale, un ensemble 25 de conduites calibrées montées en parallèle, chaque conduite calibrée étant pourvue d'une vanne en tout ou rien, et il est prévu des moyens de commande desdites vannes.According to the invention, the device for regulating the flow comprises, bypassing on said main pipe, a set 25 of calibrated pipes mounted in parallel, each calibrated pipe being provided with an all-or-nothing valve, and means are provided. for controlling said valves.
Ainsi, grâce au calibrage des conduites, calibrage que la technologie actuelle permet d'obtenir avec une excellente préci-30 sion, le débit est réglé de façon extrêment 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 valeurs de débit 35 utiles pour le traitement.Thus, thanks to the calibration of the pipes, calibration that current technology makes it possible to obtain with excellent precision, the flow rate is regulated 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 flow values useful for the treatment.
L'utilisation de vannes en tout ou rien permet d'avoir un temps de réponse quasiment nul.The use of all-or-nothing valves allows for 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 calculée automatiquement à partir des paramètres du traitement.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 calculated automatically from the parameters of the treatment.
5 Avantageusement, les conduites calibrées sont des condui tes de décharge, le liquide soustrait de la conduite principale pouvant être recyclé.Advantageously, the calibrated pipes are discharge pipes, the liquid subtracted from the main pipe can be recycled.
Avantageusement, les conduites calibrées sont prises sur une conduite de décharge collective piquée sur la conduite 10 principale. Un tel dispositif s'est avéré particulièrement satisfaisant à l'utilisation, en n'induisant dans la conduite principale aucune pertubation hydraulique notable.Advantageously, the calibrated pipes are taken from a collective discharge pipe pricked from the main pipe. Such a device has been found to be particularly satisfactory in use, by inducing no significant hydraulic disturbance in the main pipe.
L'invention sera mieux comprise grâce à la description qui va suivre d'un mode particulier de réalisation donné à titre 15 d'exemple non limitatif.The invention will be better understood from the following description of a particular embodiment given by way of nonlimiting example.
* Il sera fait référence à la figure unique annexée qui représente schématiquement le dispositif de l'invention.* Reference will be made to the single appended figure which 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, 20 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 opposé.The main pipe 1 is seen there, intended, in this embodiment, to supply cooling water, via a distribution chamber 2 with an annular slot, a pipe 9, in the axis of which a bar runs. made of steel 10 to be cooled, surrounded by an envelope of water (not shown) circulating in the same direction - according to the figure - or in an opposite direction.
Conformément à l'invention, on a piqué sur la conduite 25 principale 1 une conduite de décharge collective 3 sur laquelle sont dérivées en parallèle des conduites calibrées 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 prin-30 cipale 1.In accordance with the invention, a collective discharge line 3 has been stuck on the main pipe 1 on which are calibrated pipes parallel 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 the water in the circuit of the main pipe 1.
Les vannes 5 sont commandées par un microprocesseur 7, qui peut également commander une vanne 8 d'arrêt général placée sur la conduite 1 en amont du point de piquage de la conduite collective 3 dans le sens de circulation de l'eau de refroidissement. 35 Le système peut fonctionner simplement de la manière I suivante : la conduite d'alimentation 1 est dimensionnée de façon ? /Ol 3 * 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 5 sont donc normalement fermées. Le processeur 7 commande alors l’ouverture d'une vanne, ou de plusieurs, afin de réduire, d'une quantité voulue, le débit d'eau dans le conduit 9.The valves 5 are controlled by a microprocessor 7, which can also control a general stop valve 8 placed on the pipe 1 upstream of the point of connection of the collective pipe 3 in the direction of circulation of the cooling water. The system can operate simply as follows: the supply line 1 is dimensioned so? / Ol 3 * that, for a given inlet pressure of the water (generally from 7 to 10 bars) ensuring a sufficient speed for the envelope of water in the cooling duct 9, a flow is obtained in the latter maximum. Under these conditions, the solenoid valves * 5 5 are therefore normally closed. The processor 7 then commands the opening of one or more valves in order to reduce the flow of water in the conduit 9 by a desired quantity.
En variante, on peut prévoir de laisser normalement les vannes 5 en position "ouverte" et commander dans ce cas leur 10 fermeture lorsqu'on veut augmenter le débit d’eau de refroidissement.As a variant, it is possible to provide for normally leaving the valves 5 in the "open" position and in this case controlling their closing when the cooling water flow rate is to be increased.
Bien entendu, entre ces deux variantes, toutes les options de fonctionnement intermédiaires sont parfaitement envisageables.Of course, between these two variants, all of the intermediate operating options are perfectly conceivable.
Par ailleurs, le choix entre l'une ou l'autre de ces deux variantes 15 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.Furthermore, the choice between one or the other of these two variants 15 may be made according to the type of valves available (valves "closed" at rest or "open" at rest), knowing that "according to type, the closing operation or the opening operation respectively is slightly faster.
Il va de soi que l'invention n'est pas limitée au refroi-20 dissement, ou au refroidissement de produits métalliques en défilement dans une gaine d'eau, mais étend son domaine d'application partout où l'on souhaite pouvoir modifier rapidement et de manière r— / «· yIt goes without saying that the invention is not limited to cooling-20 dissement, or to the cooling of metallic products in scrolling in a water sheath, but extends its field of application everywhere where one wishes to be able to modify quickly and so r— / “· y
