Title (EN) COAXIAL VALVE FOR LIQUID AND GASEOUS FLUIDS
(FR) SOUPAPE COAXIALE POUR FLUIDES LIQUIDES ET GAZEUX
Abstract: front page image
(EN)Coaxial valve for fluids, which comprises a valve body and a piston/shutter (11 ) moving in said body with respect to a baffle seat (12) between two open and closed positions. The piston/shutter (11 ) has an axial bore and an intermediate annular groove (24) between two opposite cylindrical portions (22, 23), which are placed around and conducted on seals (19, 20) mounted peripherally on corresponding portions of two sleeves fixed to the valve body and forming the input and output ducts of the fluid. The baffle seat (12) has at least a peripheral seal (28) that radially engages on an internal surface of the piston/ shutter on one side of said annular groove when the piston/shutter is in the closed position.
(FR)La présente invention concerne une soupape coaxiale pour fluides, comportant un corps de soupape et un piston/obturateur (11) se déplaçant dans ledit corps par rapport à un siège de chicane (12) entre des positions ouverte et fermée. Le piston/obturateur (11) présente un alésage axial et une rainure annulaire intermédiaire (24) entre deux parties opposées ( 22, 23) de forme cylindrique, qui sont disposées autour et conduites sur des joints (19, 20) montés de manière périphérique sur des parties correspondantes de deux manchons fixés au corps de vanne et formant les conduits d’admission et d’évacuation du fluide. Le siège de chicane (12) présente au moins un joint périphérique (28) qui est en engagement radial sur une surface interne du piston/obturateur d’un côté de ladite rainure annulaire lorsque le piston/l’obturateur est dans la position fermée.
