Description

"Vanne motorisée à deux ou trois voies'
La présente invention concerne une vanne motorisée à deux ou trois voies."Two or three way motorized valve"
The present invention relates to a two or three-way motorized valve.

Les vannes motorisées sont des vannes dont le tournant est manoeuvré par un moto-réducteur électrique dont l'arbre de sortie est accouplé au carré de commande de la vanne. Dans ces vannes, une pièce d'adaptation est interposée entre le corps de vanne et le moto-réducteur, ce qui augmente l'encombrement de l'ensemble. En outre, si l'on veut entraîneur manuellement le tournant de la vanne, il est nécessaire de retirer le moto-réducteur. Motorized valves are valves whose turn is operated by an electric gear motor, the output shaft of which is coupled to the valve control square. In these valves, an adapter piece is interposed between the valve body and the gear motor, which increases the overall size of the assembly. In addition, if you want to manually drive the valve turn, it is necessary to remove the gear motor.

Enfin, si des micro-contacts commandés par des cames sont prévus pour une programmation de son fonctionnement, les cames sont nécessairement calées sur l'arbre de sortie du moto-réducteur et sont donc situées entre le carter du réducteur et le corps de vanne, c'est-à-dire à l'intérieur de la pièce d'adaptation, ce qui les rend particulièrement inaccessibles et ne facilite pas les opérations de réglage. Finally, if micro-contacts controlled by cams are provided for programming its operation, the cams are necessarily wedged on the output shaft of the gear motor and are therefore located between the housing of the reducer and the valve body, that is to say inside the adaptation piece, which makes them particularly inaccessible and does not facilitate adjustment operations.

La présente invention se propose de pallier ces inconvenients. A cet efjèt, dans la vanne motorisée qu'elle concerne, d'une part, le corps de vanne est agencé de façon a servir de support au moto-réducteur et à son capot de protection, et, d'autre part, le réducteur est du type réversible et son arbre de sortie est muni d'un prolongement postérieur accessible sous le capot et dont l'extrémité libre est conformée pour permettre son entraînement en rotation. The present invention proposes to overcome these drawbacks. To this end, in the motorized valve that it concerns, on the one hand, the valve body is arranged so as to serve as a support for the geared motor and its protective cover, and, on the other hand, the reducer is of the reversible type and its output shaft is provided with a posterior extension accessible under the hood and the free end of which is shaped to allow it to rotate.

Ainsi, du fait de la suppression de la pièce intermédiaire d'adaptation, l'encombrement général de la vanne est réduit. Thus, due to the elimination of the intermediate adapter piece, the overall size of the valve is reduced.

En outre, pour pouvoir entraîner manuellement le tournant de la vanne, il suffit de retirer son capot et de manoeuvrer le prolongement postérieur de l'arbre de sortie du réducteur, ce qui est autorisé par la reversibilite du mouvement de ce dernier. In addition, to be able to manually drive the valve turn, it suffices to remove its cover and to maneuver the posterior extension of the output shaft of the reducer, which is authorized by the reversibility of the movement of the latter.

Suivant une caractéristique intéressante de l'invention, pour permettre de visualiser la position du tournant de la vanne, le carter est muni, dans l'axe du prolongement postérieur de l'arbre de sortie du réducteur, d'un regard à travers lequel il est possible de voir la position angulaire de l'extrémité libre du prolongement postérieur de l'arbre, elle-même pourvue de repères appropriés. According to an advantageous characteristic of the invention, in order to allow the position of the valve turn to be viewed, the casing is provided, in the axis of the posterior extension of the gearbox output shaft, with a sight through which it it is possible to see the angular position of the free end of the posterior extension of the shaft, itself provided with appropriate marks.

Dans le cas où le fonctionnement de cette vanne doit être programmé et où, par conséquent, il doit être prévu un ou plusieurs jeux de micro-contacts et de cames de commande associees, ces dernières sont calées sur le prolongement postérieur de l'arbre de sortie du réducteur, tandis que les micro-contacts sont portés par la partie postérieure du carter du réducte"r, - ce qui les rend très accessibles après retrait du capot et facilite grandement les opérations de réglage. In the event that the operation of this valve must be programmed and where, therefore, one or more sets of micro-contacts and associated control cams must be provided, the latter are wedged on the rear extension of the shaft. output of the reducer, while the micro-contacts are carried by the rear part of the reductor housing "r, - which makes them very accessible after removing the cover and greatly facilitates the adjustment operations.

Etant donné que, sans augmentation de l'encombrement de l'ensemble, io est possible de prévoir un prolongement postérieur de l'arbre de sortie du réducteur d'une longueur sensiblement égale à celle de l'arbre du moteur auquel il est parallèle, il est donc aussi possible de prévoir des jeux supplémentaires de micro-contacts et cames associées pour commander d'autres fonctions d'alimentation distinctes de celle du moteur de la vanne. Given that, without increasing the overall dimensions of the assembly, it is possible to provide a posterior extension of the output shaft of the reducer of a length substantially equal to that of the motor shaft to which it is parallel, it is therefore also possible to provide additional sets of micro-contacts and associated cams to control other supply functions distinct from that of the valve motor.

Suivant encore une autre caractéristique de l'invention, le corps de la vanne est équipé de pattes latérales permettant sa fixation à des barres supports ou similaires. According to yet another characteristic of the invention, the valve body is equipped with lateral tabs allowing it to be fixed to support bars or the like.

De toute façon, l'invention sera bien comprise à l'aide de la descrlption qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cette vanne motorisée
Figure 1 en est~une vue de côté en élévation
Figure 2 en est une vue en coupe suivant 2/2 de figure é ;
Figure 3 en est une vue en plan par-dessus, capot retire.In any case, the invention will be clearly understood with the aid of the following description, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this motorized valve
Figure 1 is a side view in elevation
Figure 2 is a sectional view along 2/2 of Figure é;
Figure 3 is a plan view from above, cover removed.

La vanne motorisée représentée sur le dessin est une vanne trois voies, respectivement (A,B et C), à tournant sphérique (29 logé dans un corps (3) et monté pivotant autour d'un axe (4) entre trois positions correspondant, respectivement, à la liaison des voies (A) et (C) (comme illustré sur la figure 2), la voie (B) étant fermée, à la fermeture des trois voies (A,B,C) après pivotement de 900 du tournant (2) et à la fermeture de la voie (A) et à la mise en communication des voies (B) et (C) après un nouveau pivotement de 900 du tournant (2). The motorized valve shown in the drawing is a three-way valve, respectively (A, B and C), with a ball valve (29 housed in a body (3) and mounted pivoting about an axis (4) between three corresponding positions, respectively, at the connection of the tracks (A) and (C) (as illustrated in Figure 2), the track (B) being closed, at the closing of the three tracks (A, B, C) after pivoting 900 of the turn (2) and when the track (A) is closed and when the tracks (B) and (C) are put into communication after a new pivoting of the turn (900)

Dans l'exempte illustré sur le dessin, les voies (A,B et C) sont équipées de raccords taraudés femelles mais il est évident qu '11 est possible de prévoir n'importe quel autre type de raccord. In the example illustrated in the drawing, the tracks (A, B and C) are fitted with female threaded connections but it is obvious that it is possible to provide any other type of connection.

L'entraînement du tournant sphérique (2) en rotation autour de son axe (4) est réalisable à partir de son carré de manoeuvre (5).  The drive of the ball (2) in rotation about its axis (4) is achievable from its operating square (5).

Cette vanne motorisée est donc destinée à être équipée d'un moto-réducteur électrique d'entraînement, c'est-à-dire d'un ensemble comportant un moteur électrique (6), un réducteur (7) logé dans un carter (8) dont la face postérieure supporte le moteur électrique (6) et dont l'arbre de sortie (9) est destiné à être accouplé à l'aide d'un organe d'accouplement (11) au carré d'entraînement (5) du tournant sphérique (2). This motorized valve is therefore intended to be equipped with an electric drive geared motor, that is to say an assembly comprising an electric motor (6), a reducer (7) housed in a casing (8 ) whose rear face supports the electric motor (6) and whose output shaft (9) is intended to be coupled by means of a coupling member (11) to the drive square (5) of the spherical turning (2).

Selon l'invention, le corps (3) de la vanne présente, sur l'une de ses faces perpendiculaire à l'axe de rotation (4) du tournant (2), un agencement en forme de platine (12) apte à recevoir l'ensemble moteur (6) réducteur (7) et son capot de protection (13) sans aucune pièce intermédiaire qui en augmenterait l'encombrement général. According to the invention, the body (3) of the valve has, on one of its faces perpendicular to the axis of rotation (4) of the turn (2), a platinum-shaped arrangement (12) capable of receiving the motor assembly (6) reducer (7) and its protective cover (13) without any intermediate part which would increase the overall size.

En outre, l'arbre de sortie (9) du réducteur (7) présente un prolongement postérieur (9a) facilement accessible après retrait du capot (13). In addition, the output shaft (9) of the reducer (7) has a posterior extension (9a) easily accessible after removal of the cover (13).

De plus, le réducteur (7) est du type à mouvement réversible, cette disposition - permet donc un entraînement manuel facile du tournant (2) de cette vanne, sans qu'il soit nécessaire de procéder préala blément au démontage et au retrait de l'ensemble moteur (6) réducteur (7). Pour cela, l'extrémité libre du prolongement postérieur (9a) de l'arbre de sortie (9) du réducteur (7) est agencé pour permettre cette manoeuvre. In addition, the reducer (7) is of the reversible movement type, this arrangement - therefore allows easy manual drive of the turn (2) of this valve, without the need to disassemble and remove the l 'motor unit (6) reducer (7). For this, the free end of the rear extension (9a) of the output shaft (9) of the reducer (7) is arranged to allow this maneuver.

Dans l'exemple illustré sur le dessin, cette extrémité libre (9b) du prolongement postérieur (9a) de l'arbre de sortie (9) du réducteur (7) est de forme carrée ou hexagonale. In the example illustrated in the drawing, this free end (9b) of the posterior extension (9a) of the output shaft (9) of the reduction gear (7) is square or hexagonal.

Dans le cas où le fonctionnement de cette vanne doit être programmé à l'aide d'un jeu de cames (15) et de micro-contacts (16) associés, cette disposition présente l'avantage de permettre de caler les cames (15) sur le prolongement postérieur (9a) de l'arbre (9), les micro-contacts associés (16) étant fixés sur la partie postérieure du carter (8) du réducteur (7). If the operation of this valve must be programmed using a set of cams (15) and associated micro-contacts (16), this arrangement has the advantage of making it possible to wedge the cams (15) on the rear extension (9a) of the shaft (9), the associated micro-contacts (16) being fixed on the rear part of the casing (8) of the reducer (7).

On conçoit aisément que cette disposition facilite considérablement les opérations de réglage du fonctionnement de cette vanne puisqu'après retrait du capot (13), les cames (15) et les micro-contacts (16) associés sont très facilement accessibles. It is easily understood that this arrangement considerably facilitates the operations for adjusting the operation of this valve since, after removal of the cover (13), the cams (15) and the associated micro-contacts (16) are very easily accessible.

Il est en outre possible de munir le capot (13), dans l'axe du prolongement postérieur (9a) de l'arbre (9), d'un regard (17) permettant de visualiser la position du tournant (2) par l'intermédiaire de la position angulaire de l'extrémité libre (9b) du prolongement postérieur (9a) de l'arbre (9) sur laquelle on peut prévoir tout moyen de repère approprié.  It is also possible to provide the cover (13), in the axis of the rear extension (9a) of the shaft (9), with a sight (17) making it possible to view the position of the turn (2) by the 'intermediate the angular position of the free end (9b) of the posterior extension (9a) of the shaft (9) on which one can provide any suitable reference means.

Enfin, comme le montre plus particulièrement la figure 2, le corps (3) de la vanne est équipé de pattes latérales (1B) permettant sa fixation à des barres-support ou tout autre organe similaire. Finally, as shown more particularly in Figure 2, the body (3) of the valve is equipped with side tabs (1B) allowing its attachment to support bars or any other similar member.

Comme il va de soi et comme il ressort de ce qui précède, l'invention ne se limite pas à la seule forme d'exécution de cette vanne motorisée décrite ci-dessus à titre d'exemple non limitatif; elle en embrasse, au contraire, toutes les variantes de réalisation.  As is obvious and as appears from the above, the invention is not limited to the sole embodiment of this motorized valve described above by way of nonlimiting example; on the contrary, it embraces all of its variant embodiments.
