Definitions
- the present invention relates to a flow reducer intended to be mounted on all the draw-off points of a water supply network and, in particular, on the taps.
- the flow restrictor is arranged upstream of the possible aerator.
- a reducer which consists of a simple calibrated washer which reduces the flow at the points of withdrawal or the pressure is too high.
- it is difficult to achieve a satisfactory adjustment in this way unless there is a complete set of washers calibrated according to different diameters. Indeed, failing to know the exact pressure at each location in the distribution network, it is impossible to determine the diameter of the washer to be adapted without carrying out successive tests.
- the adjustable flow restrictor provides, among other things, these adjustment possibilities.
- the invention relates to a variable reducer making it possible, at a point of drawing water from a distribution network, to reduce the flow rate, leaving a pipe, continuously until the closure, the reducer being characterized in that it comprises a washer with an outside diameter equal to the inside diameter of said pipe, said washer being pierced with a threaded central hole in which is screwed a screw constituted by a cylindrical rod threaded at the pitch corresponding to that of said hole, said screw having a longitudinal cylindrical bore, not opening, and advantageously centered open upstream of the flow, and radial openings, normally drilled at the bottom of the bore, from the periphery of the screw to open inside said bore.
- the reduction gear according to the invention arranged for example on a tap upstream of the aerator, therefore makes it possible to regulate the flow of water continuously, using for example a simple screwdriver. It is therefore possible to adjust the flow rate at any water distribution point, empirically, while taking the pressure into account. You just have to turn the perforated screw until the desired flow rate is obtained, whatever the upstream pressure, provided of course that it is sufficient.
- the reducer according to the invention has the possibility of completely interrupting the flow of water by closing the supply duct.
- This secondary characteristic makes it possible, for example, to condemn a tap whose mechanism is leaking, while awaiting its repair, without however condemning the entire water distribution network of the housing.
- the flow restrictor according to the invention comprises a flat washer 1 pierced with a central threaded hole 1 a into which is screwed a screw 2.
- Said screw 2 is constituted by a cylindrical threaded rod with the same pitch as the threaded hole 1 a and having a bore 2 a longitudinal advantageously centered on the screw 2 and not opening.
- the non-pierced end 2 b of the screw 2 is provided with means 2 c , well known to those skilled in the art, allowing said screw 2 to be driven in rotation.
- Such means 2 c can for example constitute a simple slot shown in the figure and allowing the engagement of a screwdriver blade but also in a square, hexagonal head, a socket head etc.
- the screw 2 also includes radial slots 3 pierced at its periphery in the same plane normally perpendicular to the axis of said screw 2 and on the side of the end presenting the means 2 c .
- These openings 3 open, on the one hand on the periphery of the screw 2 and, on the other hand, inside the longitudinal cylindrical bore 2 a .
- These lights 3 can be the number of two, three, four or more. They are preferably of the same section and regularly distributed around the axis of said screw 2.
- the washer 1 in which the screw 2 is screwed is mounted for example inside the aerator body of a tap, the outside diameter of the washer 1 corresponding with the inside diameter of said aerator, so that the face 2 b of the screw 2 having the means 2 c is turned towards the outside of the aerator and therefore accessible.
- the tap is opened, the water penetrates inside the aerator body and passes through the flow restrictor through the bore 2 a and then through the ports 3 when the screw 2 is sufficiently screwed.
- the adjustment of the flow rate is then carried out in an extremely simple manner since it suffices to turn the screw 2 for example using a screwdriver, the blade of which has been introduced into the slot 2 c of the face 2 b .
- the screw 2 is made so that by continuing the screwing, it is possible to completely shut off the water supply by covering the lower part of the openings 3 with the thickness of the washer 1. It should be noted , in this regard, it is not necessary that the washer 1 is thick enough to cover all of the lights 3. It is sufficient that it is possible to screw the screw 2 high enough. It is therefore possible to close a given drawing point, for example a tap, when it no longer works. This avoids having to shut off the water supply to the entire housing, when a tap no longer closes very well, while waiting for its repair.
- the lights 3 are preferably regularly distributed around the axis of the screw 2 of so that the final output jet is not asymmetrical.
- the openings 3 are preferably perpendicular to the axis of the screw 2 and therefore to the general direction of the flow of the water in the said screw 2, so that the exit speed of the flow, which is necessarily accelerated by the reduction in flow, does not "harden” the water outlet flow.
- the lights 3 can be oriented in the direction of the outlet, this so as to obtain an outlet flow at higher pressure while reducing the water consumption.
- the continuous adjustment obtained by simple rotation of the screw 2 makes it possible to obtain a flow rate identical to all the water draw-off points of the installation, even if the supply pressures vary significantly between these various points.
- the flow restrictor according to the invention is not intended to be continuously adjusted, but rather to be adjusted once and for all at the time of installation. In the case of its mounting on a tap, after adjustment of the reduction valve, the flow reduction valve will be hidden by the aerator grille and will no longer be accessible to the user.
- the reducer according to the invention therefore has the enormous advantage of making it possible, from a single standard reducer model, to make all the desired pressure adaptations. In addition, it leaves the possibility of adapting these settings over time, without having to modify the installation or change any part.
