Description

La présente invention est relative à un dispositif de contrôle de l'écoulement d'un fluide dans une canalisation. The present invention relates to a device for controlling the flow of a fluid in a pipe.
Dans de nombreuses installations, il est nécessaire, pour de multiples raisons, de disposer de moyens pour constater si un fluide circule dans une canalisation et, ce, dans quel sens. In many installations, it is necessary, for multiple reasons, to have means for determining whether a fluid is circulating in a pipeline and, this, in which direction.
Les moyens utilisés jusqu'à ce jour font appel à des techniques compliquées et coûteuses. The means used to date use complicated and expensive techniques.
Le dispositif de l'invention se caractérise par un manchon, transparent ou translucide, interposé sur la canalisation à contrôler, comportant intérieurement un organe mobile maintenu dans une position d'équilibre sous l'action de deux ressorts identiques. The device of the invention is characterized by a sleeve, transparent or translucent, interposed on the pipe to be checked, internally comprising a movable member maintained in a position of equilibrium under the action of two identical springs.
De préférence, l'organe mobile est constitué par une bague. Preferably, the movable member is constituted by a ring.
Si toutes les vannes contrôlant la canalisation sont fermées l'organe mobile est dans une position d'équilibre, éventuellement repérée par une marque sur le manchon. Si le fluide circule dans la canalisation, la force qu'il engendre va s'ajouter à celle de l'un des deux ressorts, l'équilibre va être rompu et l'organe va se déplacer dans le sens de la circulation du fluide. Le déplacement sera d'autant plus important que le débit est important. Dans ces conditions on comprend qu'il est possible, par étalonnage, de mesurer le débit de la canalisation. If all the valves controlling the pipeline are closed, the movable member is in a position of equilibrium, possibly marked by a mark on the sleeve. If the fluid circulates in the pipeline, the force it generates will be added to that of one of the two springs, the balance will be broken and the organ will move in the direction of circulation of the fluid. The displacement will be all the more important as the flow is important. Under these conditions it is understood that it is possible, by calibration, to measure the flow rate of the pipe.
La présente invention sera mieux comprise par la description qui va suivre faite en se référant au dessin annexé à titre d'exemple indicatif, seulement, sur lequel : The present invention will be better understood from the description which follows, given with reference to the attached drawing by way of indicative example only, in which:
<Desc/Clms Page number 2><Desc / Clms Page number 2>
-la figure 1 est une vue en coupe verticale d'un dispositif conforme à l'invention ; -la figure 2 est une vue, analogue à celle 1, montrant la position de l'organe mobile lorsqu'un fluide circule dans la canalisation. FIG. 1 is a vertical section view of a device according to the invention; FIG. 2 is a view, similar to that 1, showing the position of the movable member when a fluid circulates in the pipeline.
Le problème à résoudre consiste à matérialiser l'état de repos ou de circulation d'un fluide empruntant une canalisation 1. The problem to be solved consists in materializing the state of rest or circulation of a fluid using a pipe 1.
Selon l'invention, ce résultat est obtenu en interposant sur la canalisation 1 un manchon 2, transparent ou translucide, renfermant un organe mobile, tel qu'une bague 3, maintenu dans une position d'équilibre, sous l'action, par exemple, de deux ressorts 4 identiques. According to the invention, this result is obtained by interposing on the pipe 1 a sleeve 2, transparent or translucent, containing a movable member, such as a ring 3, maintained in a position of equilibrium, under the action, for example , two identical springs 4.
Lorsque le fluide circule dans la canalisation 1, selon la flèche F, par exemple, la force qu'il engendre déplace la bague 3 qui comprime le ressort 4 situé en aval (celui 4a de la figure 2). When the fluid circulates in the pipe 1, according to arrow F, for example, the force which it generates displaces the ring 3 which compresses the spring 4 located downstream (that 4a of FIG. 2).
Il est facile de comprendre qu'à partir de la position d'équilibre de la figure 1, il est possible, par étalonnage, de porter des graduations sur le manchon 2 et ainsi d'estimer, à tout moment, le débit de la canalisation et le sens d'écoulement. It is easy to understand that from the equilibrium position of FIG. 1, it is possible, by calibration, to carry graduations on the sleeve 2 and thus to estimate, at any time, the flow rate of the pipe. and the direction of flow.
La bague 3 est dimensionnée de façon à frotter contre la paroi interne du manchon 2, ce qui permet une bonne visualisation de la position de ladite bague même si celle-ci est plongée dans un milieu opaque. The ring 3 is dimensioned so as to rub against the internal wall of the sleeve 2, which allows a good visualization of the position of said ring even if the latter is immersed in an opaque medium.
Selon un mode de réalisation, le manchon 2 est maintenu entre deux brides 5 assemblées entre elles au moyen de boulons, schématisés par les axes 6, traversant des douilles rigides 7. Des joints 8, assurant aussi une According to one embodiment, the sleeve 2 is held between two flanges 5 assembled together by means of bolts, shown diagrammatically by the pins 6, passing through rigid bushings 7. Seals 8, also ensuring a

fonction de centrage comme cela ressort clairement du dessin, sont interposés entre les brides 5 et les extrémités correspondantes du manchon. centering function as is clear from the drawing, are interposed between the flanges 5 and the corresponding ends of the sleeve.
Pour simplifier le dessin on a supposé que les brides 5 faisaient partie intégrante des deux tronçons de la canalisation 1 mais, en réalité, lesdites brides comportent des moyens permettant leur fixation sur ladite canalisation. Ces moyens étant connus et à la portée de l'homme de l'art, ils n'ont donc pas été représentés. To simplify the drawing, it has been assumed that the flanges 5 were an integral part of the two sections of the pipe 1 but, in reality, the said flanges comprise means allowing their fixing on the said pipe. These means being known and within the reach of those skilled in the art, they have therefore not been shown.
Les produits empruntant la canalisation 1 étant, en général, très corrosifs, le manchon 2 est réalisé en verre. The products using the pipe 1 being, in general, very corrosive, the sleeve 2 is made of glass.
Pour pallier à tous risques résultant de l'utilisation de cette matière fragile qu'est le verre, l'invention prévoit une double protection. To overcome all risks resulting from the use of this fragile material that is glass, the invention provides double protection.
Le manchon 2 est entouré d'une grille métallique 9 protégeant ledit manchon des agressions extérieures, ladite grille étant, à son tour, entourée d'un tube transparent 10 susceptible de contenir le produit empruntant la canalisation 1 en cas, par exemple, d'éclatement du manchon 2. De préférence, le tube 10 est réalisé en une matière plastique présentant une bonne résistance mécanique. The sleeve 2 is surrounded by a metal grid 9 protecting said sleeve from external aggressions, said grid being, in turn, surrounded by a transparent tube 10 capable of containing the product passing through the pipe 1 in the event, for example, of bursting of the sleeve 2. Preferably, the tube 10 is made of a plastic material having good mechanical strength.
Dans l'exemple représenté, le tube 10 est disposé à l'extérieur, mais la grille 9 peut occuper cette position. In the example shown, the tube 10 is arranged outside, but the grid 9 can occupy this position.
