Abstract

Nozzle combining a venturi tube 1 with a ventilation channel casing 2 comprising a branch 4 characterised by the fact that the throat of the venturi tube 3 is perforated with openings and may be improved by a perforated adjustment ring 5. This nozzle rectifies the dynamic pressure required at the point of intersection of an attached channel in the event of simultaneous flows in the main channel without changing the characteristic of the ventilation installation. It makes it possible to improve the characteristics of a ventilator in the event of having to increase its flow rate within the scope of the application to a "controlled air extraction" installation.

Description

L'invention concerne un dispositif permettant l'entrainement d'une veine d'air secondaire aboutissant sur la périphérie de l'étranglement d'un venturi. L'étranglement dans lequel passe l'air primaire est de longueur suffisante pour définir la section de passage nécessaire de la veine d'air secondaire entre le convergeant et le divergeant. Au convergeant, la pression statique reste égale à celle de la conduite greffée. The invention relates to a device for driving a secondary air stream leading to the periphery of the throttle of a venturi. The constriction through which the primary air passes is of sufficient length to define the necessary passage section of the secondary air stream between the converging and the diverging. At the converging, the static pressure remains equal to that of the grafted pipe.

L'instrument du type *tuyères* permet de compenser la perte de débit ( perte de pression) dans un circuit aéraulique pulsé à fonctionnement discontinu sur lequel vient se greffer un second circuit muni lui aussi d'un ventilateur - au fonctionnement continu. (fig. 1 et 2)
L'appareil comprend-un venturi (1) placé sur le circuit principal discontinu (2). Selon une caractéristique principale ae l'invention, 11 étranglement (3) de ce venturi est ajouré pour permettre le passage du débit du circuit greffé continu (4), aboutissant dans une chambre périphérique au conduit ajouré et s'étendant sur une longueur suffisante pour définir la section de passage nécessaire au débit de la conduite greffée.La cham- bre périphérique est fermée extérieurement par une enveloppe préférentiellement cônique reliant les collerettes extérieures des convergeant et divergeant du venturi. Sur cette enveloppe débouche la conduite greffée orientée dans le sens de l'écoulement du fluide. Un anneau ajouré (5) suivant un perçage radialemept identique à celui de l'étranglement permet le réglage des pressions. Selon une autre caractéristique non obligatoire un clapet (6) peut être prévu sur la conduite principale en amont du venturi pour obturer le circuit aéeaulique discontinu lors des arrêts pour éviter les phénomènes parasites.The * nozzles * type instrument compensates for the loss of flow (loss of pressure) in a pulsed aeraulic circuit with discontinuous operation onto which a second circuit is added, also provided with a fan - with continuous operation. (fig. 1 and 2)
The device comprises a venturi (1) placed on the discontinuous main circuit (2). According to a main characteristic of the invention, the throttle (3) of this venturi is perforated to allow the flow of the flow from the continuous grafted circuit (4), ending in a peripheral chamber to the perforated conduit and extending over a length sufficient for define the passage section necessary for the flow rate of the grafted pipe. The peripheral chamber is closed externally by a preferentially conical envelope connecting the external flanges of the converging and diverging of the venturi. On this envelope opens the grafted pipe oriented in the direction of flow of the fluid. An openwork ring (5) following a radial hole identical to that of the throttle allows the pressures to be adjusted. According to another non-mandatory characteristic, a valve (6) can be provided on the main pipe upstream of the venturi to close the discontinuous air circuit during stops to avoid parasitic phenomena.

Parmi les applications
Parmi les applications les plus intéressantes de l'inven- tion on peut citer les circuits d'intervention pour abaisser une température d'enceinte et les circuits dits Aération controAléeII
Dans les dispositifs "venturi" existants à ce jour, le fluide circulant dans le conduite greffée imprime le mouvement nécessaire à l'entrainement du fluide de la conduite principale.Among the applications
Among the most interesting applications of the invention one can cite the intervention circuits to lower a chamber temperature and the so-called Controlled Aeration circuits II
In the "venturi" devices existing to date, the fluid flowing in the grafted pipe imparts the movement necessary for the entrainment of the fluid of the main pipe.

Dans le système proposé, le principe est inversé.In the proposed system, the principle is reversed.

En outre dans les systèmes antérieurs, la pression statique dans la conduite greffée était variable selon l'écoulement dési r du fluide. La tuyère proposée permet d'obtenir une pression constante dans cette conduite au point de convergeance.  In addition, in the prior systems, the static pressure in the grafted line was variable depending on the desired flow of the fluid. The proposed nozzle makes it possible to obtain a constant pressure in this pipe at the point of convergence.

Selon la description faite ci-dessus, les lumières àménagées dans létranglement venturi servent au passage du fluide provenant de la conduite greffée. According to the description given above, the lights provided in the venturi throttle are used for the passage of the fluid coming from the grafted pipe.

Ces lumières sont constituées d'orifices circulaires ou carrés, oblongs disposés le long de la génératrice de l'étranglement. These lights consist of circular or square, oblong orifices arranged along the generatrix of the constriction.

Les axes de perçage sont * rodXudx les uns par rapport aux autres ou en lignes parallèles et, ou croisées par rapport à l'axe de la tuyère. Sans le cône de venturi ni l'anneau portant les lumières, le fotionnement serait le suivant:
- Débit constant nominal de la conduite greffée lorsque le clapet de fluide d'admission dans la conduite principale est fermé
Débit constant réduit de la conduite greffée lorsque le fluide est admis dans la conduite principale (clapet puvert)
Avec le système proposé, le fonctionnement devient
- Débit constant nominal de la conduite greffée ( débit ajusté de la bague placée sur l'étranglement du venturi) lorsque le clapet de fluide d'admission dans la conduite principale est ferme.The drilling axes are * rodXudx relative to each other or in parallel lines and, or crossed with respect to the axis of the nozzle. Without the venturi cone or the ring carrying the lights, the operation would be as follows:
- Nominal constant flow rate of the grafted line when the inlet fluid valve in the main line is closed
Constant reduced flow of the grafted line when the fluid is admitted into the main line (puvert valve)
With the proposed system, operation becomes
- Nominal constant flow rate of the grafted pipe (adjusted flow rate of the ring placed on the throttle of the venturi) when the intake fluid valve in the main pipe is closed.

Débit constant nominal de la conduite greffée maintenu par la dépression créée dans l'anneau périphérique de l'étranglement recevant le fluide de la conduite greffée, lorsque le fluide est édmis dans la conduite principale. Nominal constant flow rate of the grafted pipe maintained by the vacuum created in the peripheral ring of the throttle receiving the fluid from the grafted pipe, when the fluid is supplied into the main pipe.

Le principe de l'appareil étant basé sur le phénomène de dépression créée par le cone venturi, la bague sert à équilibrer la pression statique, côté conduite greffée, à la même valeur que celle règnant en amont du convergeant de la conduite principale recevant le fluide de façon périodique, servant d'inducteur. The principle of the device being based on the phenomenon of depression created by the cone venturi, the ring is used to balance the static pressure, grafted pipe side, at the same value as that prevailing upstream of the convergent of the main pipe receiving the fluid periodically, serving as an inductor.

L'appareil peut remplacer Ia fonction dune valve motorisée commandée par capteur de pression différentielle, interposée sur la conduite greffée, cette régulation devant rectifier la pression dynamique nécessaire en cas d'écoulement simultané de fluide dans les 2 conduites.(fig. 2)
Le montage sans cône de venturi correspond pour le tronçon commun à un branchement en parallèle de 2 ventilateurs V 1- V 2 au point I. (voir figure 4
Pour le ventilateur V 1 de la- conduite greffée, en référence à la figure 3 relative au montage avec et sans fonctionnement du ventilateur V 2
L'augmentation de la caractéristique de l'installation I
(perte de charge) se traduit par un glissement de la courbe tho- rique du ventilateur C 2 vers un point intermédiaire sur C 3 entre
celle ci-dessus (C 2) et courbe du ventilateur conduite dérivée
( C 1) fonctionnant seul.The device can replace the function of a motorized valve controlled by a differential pressure sensor, interposed on the grafted line, this regulation having to correct the dynamic pressure necessary in the event of simultaneous flow of fluid in the 2 lines. (Fig. 2)
The assembly without venturi cone corresponds for the common section to a parallel connection of 2 fans V 1- V 2 at point I. (see figure 4
For fan V 1 of the grafted pipe, with reference to FIG. 3 relating to mounting with and without operation of fan V 2
The increase in the characteristic of the installation I
(pressure drop) results in a sliding of the theoretical curve of the fan C 2 towards an intermediate point on C 3 between
the one above (C 2) and fan duct curve bypass
(C 1) operating alone.

Le montage avec cône, où le diamètre de la conduite D est supérieur à D' D" se traduit par une modification de la caractéristique de l'installation ( perte de charge moindre du fatt de la dépression créée pour un débit d'air équivalent). En reférence à la figure 5, la répercussion sur la courbe théorique du(V) ventilateur se traduit par un glissement de M vers N pression totale moindre, augmentation de débit. The cone mounting, where the diameter of the pipe D is greater than D 'D "results in a modification of the characteristic of the installation (less pressure drop of the fatt of the depression created for an equivalent air flow) Referring to FIG. 5, the repercussion on the theoretical curve of the (V) fan results in a shift from M to N lower total pressure, increase in flow rate.

En référence à la figure 6, l'augmentation de consommation électrique correspondante peut-etre compensée par un meilleur ren liement du ventilateur
Cette dernière observation permet d'envisager l'emploi du cane à fort étranglement d pour modifier les caractéristiques d'une installation (sur laquelle la régulation décrite çi avant n'est pas nécessaire) par doublement ou triplement du débit dans la conduite greffée au moment où l'on met en service le ventilateur Vide la conduite principale. Cette dernière utilisation nécessite de vérifier le dimensionnement du moteur du ventila- teur V 1 soufflant dans la conduite dérivée.Cette dernière utilisation du cône ( pour augmenter le débit d'un des ventiliateurs) peut être employée sur des installations d'extraction d'air dites à "aération controlée".With reference to FIG. 6, the corresponding increase in electrical consumption can be compensated for by better fan connection.
This last observation makes it possible to envisage the use of the highly constricted cane d to modify the characteristics of an installation (on which the regulation described here above is not necessary) by doubling or tripling the flow rate in the line grafted at the time. where the fan is put into service Empties the main line. This last use requires checking the dimensioning of the fan motor V 1 blowing in the branch line. This last use of the cone (to increase the flow rate of one of the fans) can be used on air extraction installations say "controlled ventilation".

Le Ventilateur dérivé V 4 assure la fonction d'extraction de débit minimum, les deux ventilateurs V 1 - V 2 couplésJcelle maximum. Dans ce cas le ventilateur V 1 de la conduite dérivée, lorsqu'il fonctionne en solitaire, draine le réseau des pièces à aérer de façon constante à débit minimum (WC- Sanitaires- etc.)
Le ventilateur de la conduite principale est mis en action lorsque les locaux qu'il draine sont occupés ( chambres, séjour, cuis ne). Son fonctionnement change les caractéristiques duventilateur de la conduite dérivée, ce qui entraine-une ventilation supérieure des pièces qu'il aère (WC, Sanitaires ). La nouvelle règlementation est alors respectée.The derived fan V 4 provides the minimum flow extraction function, the two fans V 1 - V 2 coupled with the maximum. In this case, the fan V 1 of the branch line, when operating alone, drains the network of rooms to be aerated constantly at minimum flow rate (WC- Sanitary- etc.)
The main line fan is activated when the premises it drains are occupied (bedrooms, living room, kitchen). Its operation changes the characteristics of the fan of the bypass line, which results in superior ventilation of the rooms it ventilates (WC, Sanitary). The new regulations are then respected.

Dans cette configuration les 2 ventilateurs sont placée en terrasse en aval des réseaux de gaines d'aspiration des pièces ventilées. La tuyère est placée à l'intersection du refoulement des ventilateurs conduites primaire et dérivée.  In this configuration, the 2 fans are placed on the terrace downstream of the suction duct networks of the ventilated rooms. The nozzle is placed at the intersection of the discharge of the primary and derived duct fans.
