Title
(EN) SAFETY VALVE AND RADIATOR USING SUCH SAFETY VALVE
(FR) SOUPAPE DE SÉCURITÉ, ET RADIATEUR UTILISANT UNE TELLE SOUPAPE DE SÉCURITÉ
Abstract
(EN)
A safety valve (1), particularly adapted to be applied to equipment (30) containing a pressurized fluid that comprises a tubular sleeve (2) in which the following are identified: a tubular body (2a) provided with an inlet hole (3) and an outlet hole (4) of the pressurized fluid; a shutter unit (5) of the inlet hole (3) slidably housed within the tubular body (2a) and comprised between the inlet hole (3) and the outlet hole (4); retaining means (6) of the shutter unit (5) present at the outlet hole (4). The safety valve (1) also comprises a tubular flange (9) belonging to the tubular body (2a), arranged coaxially and radially distanced externally to the outlet hole (4) and provided internally with a shaped zone (10) arranged coaxially and above the retaining means (6) and configured to house a manoeuvring key.

L'invention concerne une soupape de sécurité (1) adaptée en particulier pour être appliquée à un équipement (30) contenant un fluide sous pression, et comprenant un manchon tubulaire (2) dans lequel les éléments suivants sont identifiés : un corps tubulaire (2a) pourvu d'un trou d'entrée (3) et d'un trou de sortie (4) du fluide sous pression ; une unité d'obturation (5) du trou d'entrée (3) logée de façon coulissante à l'intérieur du corps tubulaire (2a) et comprise entre le trou d'entrée (3) et le trou de sortie (4) ; des moyens de retenue (6) de l'unité d'obturation (5) présents au niveau du trou de sortie (4). La soupape de sécurité (1) comprend également une bride tubulaire (9) faisant partie du corps tubulaire (2a), disposée coaxialement et radialement à distance de l'orifice de sortie (4) et comprenant en son intérieur une zone profilée (10) disposée coaxialement et au-dessus des moyens de retenue (6) et configurée pour y loger une clé de manœuvre.
