Title
(EN) SAFETY VALVE
(FR) SOUPAPE DE SURETE
Abstract
(EN)
Safety valve, characterised in that it principally consists of a housing (1), provided with an inlet (2) and an outlet (3); a main cut off valve (4) installed in the housing (1); and means working together with the flow of liquid which with the removal of liquid and after a lapse of time shut the main cut off valve (4), which are reset in their starting position each time an equal or almost equal pressure in the liquid is created at the inlet (2) and outlet (3) of the safety valve and which when the main cut off valve (4) is shut, hold it shut as long as a well defined drop of pressure remains in existence over the main cut off valve (4), whereby these means are driven by means of a by-pass, such by means of a channel (6) that is situated apart from the main passage (5).
(FR)
Une soupape de sûreté est caractérisée en ce qu'elle consiste en un boîtier (1) pourvu d'une entrée (2) et d'une sortie (3); une soupape de détente principale (4) disposée dans ledit boîtier (1), ainsi que des moyens pour fermer ladite soupape principale (4) qui coopèrent avec le flux de liquide lorsque le liquide est évacué après un certain temps. Lesdits moyens sont remis en position de départ chaque fois qu'une pression égale ou presque égale est créée dans le liquide à l'entrée (2) et à la sortie (3) de la soupape de sûreté. Lorsque la soupape de détente (4) est fermée, lesdits moyens la maintiennent ainsi tant qu'une perte de pression bien définie se maintient dans ladite soupape (4), les moyens étant entraînés par une dérivation à travers un canal (6) éloigné du passage principal (5).
