Title (EN) HOSE-BREAK VALVE
(FR) VANNE A RUPTURE POUR TUYAU
Abstract: front page image
(EN)A hose-break valve comprises a valve housing (2) and a sliding gate (1) movable therealong and is connected with a pressure hose (5) which is surrounded by a protective sleeve (14), while defining a space (13) filled with a pressure medium. The sliding gate (1) is under the action of, on the one hand, the pressure medium in said space (13) and, on the other hand, a loading device (17) acting opposite the pressure medium. First and second pressure relieving devices (19 and 80-82, respectively) are provided for closing the valve by means of the loading device (17) when the pressure of the pressure medium in said space (13) respectively exceeds an upper limit value and falls short of a lower limit value.
(FR)Une vanne a rupture pour tuyau comprend un corps de vanne (2) et un tiroir coulissant (1) mobile le long du corps et est connectee a un tuyau sous pression (5) qui est entoure d'une gaine protectrice (14), definissant un espace (13) rempli d'un milieu sous pression. Le tiroir coulissant (1) est sous l'action d'une part du milieu pressurise se trouvant dans l'espace (13) et d'autre part d'un dispositif de charge (17) agissant de maniere opposee au milieu. Un premier et un second dispositifs de reduction de la pression (19 et 80-82, respectivement) sont prevus pour fermer la vanne a l'aide du dispositif de charge (17) lorsque la pression du milieu de pression dans l'espace (13) depasse une valeur limite superieure et tombe en-deca d'une valeur limite inferieure, respectivement.
