Abstract

L'invention porte sur un ensemble de couvercle de trou d'homme, lequel ensemble est configuré de façon à se comporter en soupape de détente lors d'un événement d'explosion, s'ouvrant de telle sorte qu'un fluide, tel que de l'air ou des gaz explosifs, peut être évacué à partir d'une zone souterraine. L'ensemble de couvercle de trou d'homme peut comprendre un couvercle de trou d'homme et un cadre, et peut être configuré de façon à limiter un mouvement du couvercle de trou d'homme par rapport au cadre en réponse à une pression accrue sur le couvercle de trou d'homme. Dans un mode de réalisation, le couvercle de trou d'homme peut comprendre des pattes ayant des surfaces en angle aptes à centrer ou à guider sensiblement le couvercle de trou d'homme dans le cadre tandis que le couvercle de trou d'homme se déplace de façon à relâcher une pression. Dans un autre mode de réalisation, une plusieurs pattes peuvent coulisser à l'intérieur du couvercle de trou d'homme de façon à permettre de configurer le couvercle de trou d'homme entre un mode de maintien et un mode de retrait.
