Title (EN) A SLIDE VALVE FOR DIRECT ACTING SHUTTING-OFF OF A PRESSURE MEDIUM IN CASE OF A HOSE RUPTURE
(FR) VANNE A TIROIR EFFECTUANT UNE COUPURE DIRECTE D"UN MILIEU DE PRESSION DANS LE CAS D"UNE RUPTURE D"UN TUBE
Abstract: front page image
(EN)A slide valve for direct-acting shutting-off of a pressure medium in case of a hose rupture, including a valve housing (1, 2), a mouth port (A and B, respectively) at either end of the valve housing, a partition (6) dividing the valve housing into two halves each facing one of said mouth ports, a valve cone (5) mounted slidable axially in both directions in the partition and having two opposite end portions (7, 8) which are of different areas and are subject to actuation by the pressure medium, and communication channels (3, 4) connecting the halves of the housing with each other. The valve cone is designed to take two positions depending on the drop in pressure across the valve, viz. a first position, called the normal working position, in which the end portion (7) of the valve cone having the greater area is nested in a valve seat in the partition (6) and pressure medium passes between the mouth ports (A, B), and a second position, called a throttle position, in which the last-mentioned end portion (7) engages and closes its associated mouth port (A) and the pressure medium is throttled down. The characteristic feature of the invention is that a fluid distribution disc (14) provided with apertures is arranged at the mouth port (B) associated with the end portion of the valve cone having the smaller area.
(FR)Une vanne a tiroir de fermeture a action directe d"un milieu de pression dans le cas de rupture d"un tube, comprend un corps de vanne (1, 2), un orifice (A et B respectivement) de chaque cote du corps de vanne, une separation (6) divisant le corps de vanne en deux moities, chacune d"elles etant en face de l"un des orifices, un cone de vanne (5) monte en coulissement axial dans deux directions dans la cloison de separation et ayant deux parties extremes opposees (7, 8) ayant des surfaces differentes et soumises a l"action du milieu sous pression, et des canaux de communication (3, 4) mettant en communication les moities du corps. Le cone de vanne est concu pour prendre deux positions en fonction de la chute de pression au niveau de la soupape a savoir une premiere position denommee position normale de travail dans laquelle la partie extreme (7) du cone de vanne ayant la plus grande surface est logee dans un siege dans la cloison de separation (6), le milieu de pression passant entre les orifices (A, B), et une seconde position denommee position d"etranglement dans laquelle la partie extreme mentionnee en dernier (7) engage et ferme son orifice associe (A) et le debit du milieu de pression est ralenti. Le trait caracteristique de ce dispositif consiste en un disque de distribution de fluide (14) pourvu d"ouvertures et dispose au niveau de l"orifice (B) associe a la partie extreme du cone de vanne ayant la plus petite surface.
