Abstract

The controller is attached to the valve head of a pressure regulator in an existing installation. The controller is attached to the valve head by a rod, which connects it to a piston. The space between the piston and the valve head is connected by a flexible pipe to the inlet side of the regulator. A spring behind the piston tends to close the regulator valve against the incoming flow. The piston can be pushed fully inward so the flow is completely blocked by operating an external rod that slides in a hole in the top of the spring. If the rod is placed in an intermediate position the opening of the regulator valve can be limited to limit flow.

Description

La présente invention concerne un dispositif permettant de donner à un régulateur ou stabilisateur de pression hydraulique existant les fonctions suivantes: - Ouverture à une pression amont minimum - Anti-retour en cas de baisse de pression en amont du régulateur ou du
stabilisateur - Condamnation physique de l'écoulement sans démontage de pièces à
l'aval du régulateur ou du stabilisateur.The present invention relates to a device making it possible to give an existing hydraulic pressure regulator or stabilizer the following functions: - Opening at a minimum upstream pressure - Non-return in the event of a pressure drop upstream of the regulator or
stabilizer - Physical blockage of the flow without disassembly of parts to
downstream from the regulator or stabilizer.

- Utilisation maîtrisée du fonctionnement simultanée de plusieurs
écoulements
Le dispositif selon l'invention permet de remédier aux inconvénients suivants: - Impossibilité de mise en pression d'un réseau hydraulique si les écoulements
sont normalement ouverts - Retour du fluide entre l'aval et l'amont en cas de baisse de pression amont
Augmentation des capacités hydrauliques d'un réseau en cas d'utilisation
non-simultanée des écoulements
Démontage de pièces à l'aval du régulateur ou du stabilisateur de pression en
cas de condamnation physique de l'écoulement.- Controlled use of the simultaneous operation of several
flows
The device according to the invention overcomes the following drawbacks: - Impossibility of pressurizing a hydraulic network if the flows
are normally open - Fluid return between downstream and upstream in the event of a drop in upstream pressure
Increase of the hydraulic capacities of a network in case of use
non-simultaneous flows
Disassembly of parts downstream of the pressure regulator or stabilizer
physical condemnation of the flow.

Le dispositif selon l'invention se présente sous la forme d'un vérin
dont la tige est solidaire de la partie régulatrice ou stabilisatrice du
régulateur ou du stabilisateur de pression et dont le corps est fixé à celui
du régulateur ou du stabilisateur de pression.The device according to the invention is in the form of a jack
whose rod is integral with the regulating or stabilizing part of the
pressure regulator or stabilizer and whose body is attached to that
pressure regulator or stabilizer.

La chambre du vérin côté tige est alimentée à la pression hydraulique
amont du régulateur ou du stabilisateur de pression au travers d'un
tuyau de raccord.The rod side cylinder chamber is supplied with hydraulic pressure
upstream of the pressure regulator or stabilizer through a
connecting pipe.

Entre le piston et le fond de chambre se trouve un ressort taré à la pression
d'ouverture amont désirée.Between the piston and the chamber bottom is a pressure calibrated spring
upstream opening desired.

Le piston peut être bloqué en position basse par un système mécanique à
clé codée.The piston can be locked in the low position by a mechanical system with
coded key.

La f gure I représente le dispositif en position repos non condamnée La f gure 2 représente le dispositif en position condamnée La f gure 3 représente le dispositif en position marche
Lorsque le dispositif est en position condamnée (figure 2), l'écoulement est impossible quelle que soit la valeur de la pression hydraulique amont (P amont).Figure I shows the device in the non-locked rest position. Figure 2 shows the device in the locked position. Figure 3 shows the device in the on position.
When the device is in the locked position (Figure 2), the flow is impossible regardless of the value of the upstream hydraulic pressure (P upstream).

Lorsque le dispositif est en position non condamnée , l'écoulement est impossible si la pression hydraulique amont, appliquée sur le régulateur (stabilisateur) et sur le piston du vérin, est inférieure au tarage du ressort (figure 1).When the device is in the non-locked position, flow is impossible if the upstream hydraulic pressure, applied to the regulator (stabilizer) and to the cylinder piston, is lower than the spring setting (Figure 1).

Si cette pression est supérieure l'écoulement devient possible (figure 3) et la fonction régulation (stabilisation) de base en service.If this pressure is higher, flow becomes possible (Figure 3) and the basic regulation (stabilization) function in service.

La figure n 4 indique la courbe de fonctionnement du régulateur (stabilisateur) sans le dispositif.Figure 4 shows the operating curve of the regulator (stabilizer) without the device.

La figure n 5 indique la courbe de fonctionnement du régulateur (stabilisateur) avec ledispositif.Figure n 5 shows the operating curve of the regulator (stabilizer) with the device.

Selon les modes particuliers de réalisation, les pièces auront des dimensions proportionnelles aux efforts appliqués.According to the particular embodiments, the parts will have dimensions proportional to the forces applied.

Le système de condamnation physique du dispositif peut être verrouillé par un système mécanique ou non. The physical locking system of the device can be locked by a mechanical system or not.
