Abstract

This invention relates to a device which makes it possible to reduce considerably the water pressure at the outlet of a flexible or rigid pipe serving for watering garden plants without reducing the flow rate. The pressurised water arrives via the pipe 1, escapes via the orifices 5 pierced in the wall, the end being plugged up by a welded disc 4 or a screwed-in plug. The water pressure is dissipated (broken) by contact with the wall of the tube 2 and the water then flows out, under no significant pressure, towards the end of the tube 2. This device is particularly intended for watering garden plants (vegetables and flowers), avoiding damage produced by a pressurised-water supply.

Description

DESCRIPTION
La présente invention concerne un dissipateur de pression destiné à l'arrosage de plantes de jardins, et qui permet d'effectuer cette opération sans dégrader le terrain lorsque l'alimentation en eau est distribuée par une canalisation sous forte pression.DESCRIPTION
The present invention relates to a pressure sink intended for watering garden plants, and which makes it possible to carry out this operation without degrading the ground when the water supply is distributed by a pipe under high pressure.

Le dispositif est essentiellement constitué de deux tubes 1 et 2 cylindriques et concentriques formant une chambre de décompression.The device essentially consists of two cylindrical and concentric tubes 1 and 2 forming a decompression chamber.

La paroi du tuyau intérieur est percée de plusieurs trous 5 disposés en quinconce dont le nombre et le diamètre sont à déterminer en fonction de la réduction de pression souhaitée qui peut varier selon que l'on peut arroser des plantations fragiles (semis, fleurs, légumes) ou des arbustes peu enracinés.The wall of the inner pipe is pierced with several holes 5 arranged in staggered rows the number and diameter of which are to be determined as a function of the desired reduction in pressure which may vary depending on whether fragile plantations (seedlings, flowers, vegetables) ) or poorly rooted shrubs.

C'est ainsi qu'une pression de 15 kg à l'entrée du tube 1 a pu être réduite, au cours des essais à quelques grammes à la sortie du tube 2 sans diminution de débit soit 2,6 1 à la seconde ou 9,360 litres à l'heure. Thus, a pressure of 15 kg at the inlet of tube 1 could be reduced, during the tests to a few grams at the outlet of tube 2 without reduction in flow rate, ie 2.6 1 per second or 9.360 liters per hour.

L'avantage de ce dispositif réside donc dans la possibilité de réduire la pression de l'eau sans réduire le débit.The advantage of this device therefore lies in the possibility of reducing the water pressure without reducing the flow rate.

L'ensemble peut être réalisé en métal ou en matière plastique. La pièce 3 d'assemblage des deux tubes 1 et 2 peut être soudée ou vissée ou encore adaptée par tout autre moyen à la convenance du fabricant.The assembly can be made of metal or plastic. The part 3 for assembling the two tubes 1 and 2 can be welded or screwed or even adapted by any other means at the convenience of the manufacturer.

La pastille 4 d'obturation du tube 1 peut également être soudée ou remplacée par un bouchon vissé.The patch 4 for closing the tube 1 can also be welded or replaced by a screw cap.

Selon une variante le tube 1 peut être aménagé pour recevoir un raccord "express". According to a variant, the tube 1 can be arranged to receive an "express" connection.
