Description

VANNE DE COMMANDE ET DE REGULATION DE
L'ECOULEMENT D'UN FLUIDE
La présente invention concerne une vanne de commande et de régulation de l'écoulement d'un fluide.CONTROL AND REGULATION VALVE
THE FLOW OF A FLUID
The present invention relates to a valve for controlling and regulating the flow of a fluid.

I1 existe de telles vannes dont l'organe obturateur est constitué par un volet pivotant, qui est situé à l'intérieur d'une chambre ménagée dans la paroi du conduit que comprend le corps de la vanne pour l'écoulement du fluide, qui est mobile entre une position d'ouverture permettant l'écoulement du fluide et une position de fermeture arrêtant cet écoulement, et dont le mouvement de pivotement est commandé, depuis l'extérieur de la vanne, par un levier qui en est solidaire en rotation. I1 exist such valves whose shutter member is constituted by a pivoting flap, which is located inside a chamber formed in the wall of the conduit that includes the valve body for the flow of the fluid, which is movable between an open position allowing the flow of the fluid and a closed position stopping this flow, and the pivoting movement of which is controlled, from outside the valve, by a lever which is integral therewith in rotation.

Les vannes de ce type sont complexes à fabriquer puisque leur corps est au moins en deux parties afin de rendre possible le montage du volet dans la chambre précitée. La nécessité de réaliser ce corps en plusieurs parties devant être ultérieurement assemblées greve sensiblement le prix de revient de telles vannes. Valves of this type are complex to manufacture since their body is at least in two parts in order to make possible the mounting of the shutter in the aforementioned chamber. The need to make this body in several parts which must be subsequently assembled significantly increases the cost price of such valves.

La présente invention vise à remédier à cet inconvénient. The present invention aims to remedy this drawback.

A cette fin, la vanne qu'elle concerne, du type comprenant un corps percé de part en part par un conduit pour l'écoulement du fluide et équipé d'un volet obturateur mobile entre une position de fermeture et une position d'ouverture de ce conduit, se caractérise en ce que le volet est monté à son extrémité par où le fluide pénètre dans le conduit et vient, en position de fermeture, obturer l'orifice du conduit, la paroi du corps de la vanne bordant l'ouverture de cet orifice constituant le siège du volet. To this end, the valve which it relates to, of the type comprising a body pierced right through by a conduit for the flow of the fluid and equipped with a movable shutter flap between a closed position and an open position of this conduit is characterized in that the flap is mounted at its end through which the fluid enters the conduit and comes, in the closed position, to close the orifice of the conduit, the wall of the valve body bordering the opening of this orifice constituting the seat of the shutter.

Une telle vanne est particulièrement simple à réaliser puisque son corps peut être monobloc. Such a valve is particularly simple to produce since its body can be in one piece.

En position de fermeture, le volet subit la pression du fluide, ce qui permet d'assurer ou de concourir à assurer l'étanchéité de la vanne. In the closed position, the shutter undergoes the pressure of the fluid, which makes it possible to ensure or contribute to ensuring the tightness of the valve.

De préférence, le volet est monté pivotant autour d'un axe de rotation parallèle à l'axe du conduit et avantageusement, cet axe de rotation du volet est situé à ltextérieur du conduit et la course du volet est telle qu'en position maximale d'ouverture, ce dernier soit totalement dégagé de l'orifice de manière à ce que l'écoulement du fluide puisse se faire à travers l'entière section du conduit, sans gêne. Preferably, the shutter is pivotally mounted about an axis of rotation parallel to the axis of the duct and advantageously, this axis of rotation of the shutter is located inside the duct and the stroke of the shutter is such that in the maximum position d 'opening, the latter is completely clear of the orifice so that the flow of fluid can be done through the entire section of the duct, without discomfort.

Pour renforcer l'étanchéité de la vanne, un joint annulaire est placé entre le volet et la paroi du corps de la vanne bordant l'orifice du conduit, ainsi que des moyens élastiques tendant à presser le volet contre cette paroi.  To strengthen the tightness of the valve, an annular seal is placed between the shutter and the wall of the valve body bordering the orifice of the duct, as well as elastic means tending to press the shutter against this wall.

Selon une forme de réalisation préférée de cette vanne, le volet est solidaire de l'une des extrémités d'une tige dont l'autre extrémité comporte un levier de manoeuvre, la tige pouvant pivoter dans un alésage ménagé dans le corps de la vanne, alésage dont le diamètre est augmenté du côté du levier précité afin de constituer un logement pour un ressort hélicoïdal engagé coaxialement sur la tige, ce ressort étant en appui, par l'une de ses extrémités, contre le fond du logement et, par son autre extrémité, contre un écrou porté par l'extrémité de la tige. According to a preferred embodiment of this valve, the flap is integral with one of the ends of a rod, the other end of which comprises an operating lever, the rod being able to pivot in a bore formed in the body of the valve, bore whose diameter is increased on the side of the aforementioned lever in order to constitute a housing for a helical spring engaged coaxially on the rod, this spring being in abutment, by one of its ends, against the bottom of the housing and, by its other end, against a nut carried by the end of the rod.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée de la vanne selon l'invention. In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, a preferred embodiment of the valve according to the invention.

Figure 1 en est une vue de face, et
Figure 2 en est une vue selon II-II de figure 1.Figure 1 is a front view, and
Figure 2 is a view along II-II of Figure 1.

Les figures représentent sous différents angles une vanne 2 dont le corps 3, monobloc, comprend une bride carrée 4 percée de trous 5 pour sa fixation par exemple à une cuve (non représentée) et un conduit 6 le traversant de part en part et ménageant un orifice 6a d'entrée du fluide s'écoulant à travers le conduit 6 et un orifice 6b de sortie. The figures represent from different angles a valve 2 whose body 3, in one piece, comprises a square flange 4 pierced with holes 5 for fixing it for example to a tank (not shown) and a conduit 6 passing right through it and providing a orifice 6a for the inlet of the fluid flowing through the conduit 6 and an outlet orifice 6b.

La vanne 2 comprend un volet 10 monté à proximité de son extrémité par où le fluide pénètre dans le conduit 6. Le volet 10 est solidaire de l'une des extrémités d'une tige 11 perpendiculaire à lui-même, engagée et pouvant pivoter dans un alésage 12 ménagé dans un prolongement latéral extérieur 3a du corps 3, et à l'autre extrémité de laquelle est monté, au moyen d'une vis 13, un levier de manoeuvre 14. The valve 2 comprises a flap 10 mounted near its end through which the fluid enters the conduit 6. The flap 10 is integral with one of the ends of a rod 11 perpendicular to itself, engaged and able to pivot in a bore 12 formed in an external lateral extension 3a of the body 3, and at the other end of which is mounted, by means of a screw 13, an operating lever 14.

Le diamètre de l'alésage 12 est augmenté du côté du levier 14 de manière à ménager- un logement 17 pour un ressort hélicoïdal 18, engagé coaxialement sur la tige 1 1 et en appui, par l'une de ses extrémités, contre le fond du logement 17 et, par l'autre de ses extrémités, contre un écrou 19 vissé sur une partie filetée de la tige 11. The diameter of the bore 12 is increased on the side of the lever 14 so as to provide a housing 17 for a helical spring 18, engaged coaxially on the rod 1 1 and pressing, by one of its ends, against the bottom of the housing 17 and, by the other of its ends, against a nut 19 screwed onto a threaded part of the rod 11.

La tige 1 1 comprend une vis 25 engagée dans un évidement 26 en arc de cercle ménagé dans le prolongement 3a et délimité notamment par des parois 27 et 28, ainsi que des bagues d'étanchéité 30,31 et 32. Le fond de l'évidement 26, au contact duquel se trouve la vis 25, est usiné de manière à former une rampe, la partie la moins profonde de l'évidement 26 étant du côté de la paroi 27. The rod 1 1 comprises a screw 25 engaged in a recess 26 in an arc formed in the extension 3a and delimited in particular by walls 27 and 28, as well as sealing rings 30, 31 and 32. The bottom of the recess 26, in contact with which the screw 25 is located, is machined so as to form a ramp, the shallowest part of the recess 26 being on the side of the wall 27.

En outre, la paroi 3b du corps 3 bordant l'ouverture de l'orifice 6a comprend une gorge annulaire dans laquelle est engagé un joint 36. In addition, the wall 3b of the body 3 bordering the opening of the orifice 6a comprises an annular groove in which a seal 36 is engaged.

Du fait du pivotement de la tige 1 1 lors de la manoeuvre du levier 14, le volet 10 est mobile entre une position de fermeture, dans laquelle il obture l'orifice 6a, et une position d'ouverture, dans laquelle il est totalement dégagé de cet orifice 6a de manière à ce que l'écoulement du fluide puisse se faire à travers l'entière section du conduit 3. La paroi 3b constitue le siège du volet 3. Due to the pivoting of the rod 1 1 during the operation of the lever 14, the flap 10 is movable between a closed position, in which it closes the orifice 6a, and an open position, in which it is completely released of this orifice 6a so that the fluid can flow through the entire section of the conduit 3. The wall 3b constitutes the seat of the flap 3.

En position de fermeture, le volet 10 subit la pression du fluide, qui tend à le plaquer contre la paroi 3b. Ceci concourt à assurer l'étanchéité de la vanne 2, principalement réalisée grâce au joint 36 et au pressage du volet 10 contre la paroi 3b sous l'action du ressort 18, dont la force de rappel peut être réglée par vissage ou dévissage de l'écrou 19. In the closed position, the flap 10 undergoes the pressure of the fluid, which tends to press it against the wall 3b. This contributes to sealing the valve 2, mainly achieved by means of the seal 36 and by pressing the flap 10 against the wall 3b under the action of the spring 18, the restoring force of which can be adjusted by screwing or unscrewing the nut 19.

Les parois 27 et 28 jouent le rôle de butées de fin de course de rotation de la tige 11. Le fond en forme de rampe de l'évidement 26 contre lequel s'appuie la vis 25 permet, lors de la rotation de la tige 11, un décollement rapide du volet 10 et du joint 36 qui évite un cisaillement de ce dernier et en limite l'usure.  The walls 27 and 28 play the role of end-of-travel stops for rotating the rod 11. The ramp-shaped bottom of the recess 26 against which the screw 25 rests allows, during the rotation of the rod 11 , a rapid detachment of the flap 10 and the seal 36 which prevents shearing of the latter and limits wear.
