Abstract

L'invention concerne un régulateur de pression de gaz axiale à action directe de pression de sortie et d'entrée, dans lequel régulateur, selon la variante de réalisation de base, dans un boîtier (01), dans des paliers lisses (17), est disposée de façon à pouvoir se déplacer axialement une buse (03). A l'opposé de la buse équilibrée mobile (03) se trouve un obturateur fixe serré (04) avec des joints d'étanchéité (041), qui a une symétrie double. Sur le côté gauche du boîtier (01), un raccord d'entrée (14) est attaché par l'intermédiaire de bobines et de joints d'étanchéité, tandis que sur le côté droit du boîtier (01), un raccord de sortie (021) est attaché par l'intermédiaire de bobines et de joints d'étanchéité. Dans le corps du boîtier (01), une ligne de trop-plein (011) est réalisée, celle-ci reliant la buse (03) au raccord de sortie (021). Au boîtier (01) est relié par des vis (091) un boîtier (09) d'un ensemble membrane (10), tandis que, par un raccord (092), un tube à impulsions (093) est relié à l'ensemble de sortie (02), tandis que, par un raccord (094), il est relié au boîtier (09). Dans le boîtier (09), dans un cocon (08), un levier articulé de façon inversée (05) est relié de façon à pouvoir tourner par un axe (07), ou, autrement dit, par son extrémité inférieure, par l'intermédiaire d'un axe (06), à la buse (03), tandis que, dans le levier de partie supérieure (05), il est relié de façon à pouvoir tourner, par l'intermédiaire d'un axe (103) et d'un rouleau (104), à un tendeur inférieur (102) d'une membrane (M) de l'ensemble membrane (10), qui est, par des vis (101) fixé entre le boîtier (09) et un boîtier (11). Un ressort de régulation (12) est supporté sur l'ensemble de membrane (10), et, de l'autre côté, il est pressé par une vis de régulation (13) qui est incurvée dans un capot (132) et qui est fixée par un écrou (133).
