Abstract

L'invention concerne un composant de tuyau destiné à empêcher une pression négative, comprenant un tuyau (1), une ouverture d'inspection (2) formée sur le tuyau (1), ainsi qu'un déflecteur (3) relié adéquatement à l'intérieur de l'ouverture d'inspection (2). Un tube de colonne montante en forme de cube (4) est fixé, au moyen d'une vis, sur un emplacement du tuyau (1) correspondant à l'ouverture d'inspection (2). Un capuchon mobile (5) est relié par filetage à une partie supérieure du tube de colonne montante en forme de cube (4). Un joint d'étanchéité est disposé au niveau du raccord entre le capuchon mobile (5) et le tube de colonne montante en forme de cube (4). Le tuyau (1) est pourvu en son intérieur d'un détecteur de fuite. Une extrémité d'entrée du tuyau (1) est pourvue d'une soupape de commutation électrique. L'invention concerne également un microcontrôleur. Une borne d'entrée et une borne de sortie du microcontrôleur sont raccordées respectivement au détecteur de fuite et à la soupape de commutation électrique. Ce composant de tuyau destiné à empêcher une pression négative présente d'excellentes fonctions de prévention de fuite, permet une inspection et un accès aisés, offre une résistance à la corrosion et une ténacité améliorées et présente une longue durée de vie utile. Le composant de tuyau selon l'invention est également doté d'une fonction d'auto-stérilisation.
