Abstract

Device for testing fluid flow in a conduit comprises a transparent or translucent collar (2) placed in the conduit to be tested with a movable ring (3) held in an equilibrium position by two identical springs (4). When there is a fluid flow the ring is displaced in the direction of flow.

Description

<Desc / Clms Page number 1>

The present invention relates to a device for controlling the flow of a fluid in a pipe.

 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.

 The means used to date use complicated and expensive techniques.

 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.

 Preferably, the movable member is constituted by a ring.

 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.

 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>

 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.

 The problem to be solved consists in materializing the state of rest or circulation of a fluid using a pipe 1.

 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.

 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).

 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.

 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.

 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

<Desc / Clms Page number 3>

 centering function as is clear from the drawing, are interposed between the flanges 5 and the corresponding ends of the sleeve.

 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.

 The products using the pipe 1 being, in general, very corrosive, the sleeve 2 is made of glass.

 To overcome all risks resulting from the use of this fragile material that is glass, the invention provides double protection.

 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.

 In the example shown, the tube 10 is arranged outside, but the grid 9 can occupy this position.
