Title (EN) A HYDRANT AND USE OF A HYDRANT
(FR) BORNE D'INCENDIE ET UTILISATION D'UNE BORNE D'INCENDIE
Abstract:
(EN) Disclosed is a hydrant (1) comprising a riser pipe (2) through which a fluid flow may be guided and a blocking disc (3) arranged to be displaced in and out of the fluid flow to block the fluid flow through the riser pipe (2). The hydrant (1) also comprises a stem (4) arranged to actuate the blocking disc (3) through a gearing (5), wherein the gearing (5) of the hydrant (1) comprises a gear nut (6) arranged to engage the stem (4) so that when the stem (4) and the nut (6) are mutually rotated, the nut (6) is displaced along the longitudinal direction of the stem (4). The gearing (5) of the hydrant (1) further comprises a gear sleeve (7) including a sleeve helical track (8), wherein the gear sleeve (7) is connected to the blocking disc (3), and a gear housing (9) comprising a housing helical track (10), wherein the position of the gear housing (9) is fixed in relation to the riser pipe (2), and wherein the gear nut (6) is arranged to engage both the sleeve helical track (8) and the housing helical track (10). Use of a hydrant (1) is also disclosed.
(FR) L'invention concerne une borne d'incendie (1) comprenant une colonne montante (2) à travers laquelle un écoulement de fluide peut être guidé et un disque de blocage (3), conçu pour être déplacé dans le flux de fluide et hors de celui-ci afin de bloquer l'écoulement de fluide dans la colonne montante (2). La borne d'incendie (1) comprend également une tige (4) conçue pour actionner le disque de blocage (3) par l'intermédiaire d'un engrenage (5), l'engrenage (5) de la borne d'incendie (1) comprenant un écrou d'engrenage (6) conçu pour venir en prise avec la tige (4) de sorte que lorsque la tige (4) et l'écrou (6) sont tournés l'un par rapport à l'autre, l'écrou (6) est déplacé dans la direction longitudinale de la tige (4). L'engrenage (5) de la borne d'incendie (1) comprend en outre une douille portant des engrenages (7) qui comprend un filetage hélicoïdal de douille (8), ladite douille (7) étant reliée au disque de blocage (3) ; et un carter d'engrenage (9) comprenant un filetage hélicoïdal de carter (10), la position du carter d'engrenage (9) étant fixe par rapport à la colonne montante (2), et l'écrou d'engrenage (6) étant conçu pour venir en prise à la fois avec le filetage hélicoïdal de la douille (8) et le filetage hélicoïdal du carter (10). L'invention concerne également l'utilisation d'une borne d'incendie (1).
