Method for suppressing pressure pulses in pipelines

FIELD: pipes. SUBSTANCE: invention relates to methods and means for suppressing pressure pulsations of a liquid (water hammer) or a gas in pipelines. The method consists in the fact that the liquid or gas flow of the pipeline wherein the pressure pulses act is divided into N parts further directed to channels with different delays due to the different lengths thereof, therefore, pulses from different channels with a power reduced by N are summed up at the output, coming in succession due to the different times of passage through the channel. Accordingly, the pulse front is spread and the undesirable impact on the pipeline is reduced. The delay of each channel is calculated by the formula Tn=T+delta*(N-l), wherein T is the delay of the shortest channel, Tn is the delay in the N th channel, delta is the increment of the channel delay when the number thereof is increased by one, N is the number of the channel.

En outre, le profil de la membrane présente selon une section en coupe axiale de la membrane au moins une ondulation faisant saillie vers l'intérieur de la chambre (34) dans la position de repos pour former une zone de déformation préférentielle vers l'intérieur de la chambre (34) dans la position de contrainte de la membrane (32). The invention relates to a device (10) for damping pulsations of a fluid, of the type comprising a housing (12) which comprises an upper part (16) and a lower part (18) and an elastically deformable membrane (32) between a resting position and a stress position, arranged inside the housing (12) so that the membrane (32) delimits with the lower part (18) a fluid-tight chamber (34). More particularly, the membrane (32) has, in the rest position, a generally convex shape towards the outside of the chamber (34), of revolution about a main axis (X) of the device (10). In addition, the profile of the membrane has, in an axial section of the membrane, at least one corrugation projecting towards the inside of the chamber (34) in the rest position to form a zone of preferential deformation towards the inside. the chamber (34) in the constrained position of the membrane (32).

AIR INTRODUCTION DEVICE FOR A HYDROPNEUMATIC TANK

Dispositif d'introduction d'air 7 dans un système hydraulique comprenant un réservoir hydropneumatique 3 monté sur une canalisation 1. Le dispositif d'introduction d'air 7 est monté de façon à introduire de l'air dans une zone en eau du système où la pression Ps est soit inférieure, soit légèrement supérieure à la pression atmosphérique. Le dispositif est actif lorsqu'un manque d'air est à combler dans le réservoir hydropneumatique 3. Device for introducing air 7 into a hydraulic system comprising a hydropneumatic reservoir 3 mounted on a pipe 1. The device for introducing air 7 is mounted so as to introduce air into a water zone of the system where the pressure Ps is either lower or slightly higher than atmospheric pressure. The device is active when there is a lack of air in the hydropneumatic tank 3.
