Abstract

L'invention a trait à des perfectionnements apportés aux vannes. Elle a pour objet une soupape pour contrôler la pression résiduelle d'un système à fluide sous pression. comportant une soupape de pression résiduelle préréglée. L'ensemble de la soupape de pression résiduelle est déplaçable de façon hermétique dans un passage d'écoulement 11. Est également placée dans ledit passage, une première butée 21, 32 contre laquelle le siège 12, 14 de la soupape de pression résiduelle doit buter lorsque ladite soupape est déplacée au moyen de la pression résiduelle dans le système ou au moyen de la pression résiduelle combinée à un ressort 19 disposé entre le siège de la soupape et la paroi dudit passage. La soupape de pression résiduelle peut être ouverte au moyen d'une pression dans le système excédant la pression résiduelle. Une seconde butée 33 est placée dans le passage 11 sur le côté opposé de la soupape de pression résiduelle, contre laquelle le corps 15, 16, 17 de ladite soupape doit buter à la suite d'un déplacement de celle-ci au moyen d'un dispositif externe ou d'un fluide sous pression extérieur, ladite soupape de pression résiduelle étant ouverte de force. Application notamment aux bouteilles de gaz rechargeables.The invention relates to improvements made to valves. It relates to a valve for controlling the residual pressure of a pressurized fluid system. with a pre-set residual pressure valve. The assembly of the residual pressure valve is hermetically movable in a flow passage 11. Also placed in said passage is a first stop 21, 32 against which the seat 12, 14 of the residual pressure valve is to abut. when said valve is moved by means of the residual pressure in the system or by means of the residual pressure combined with a spring 19 disposed between the seat of the valve and the wall of said passage. The residual pressure valve can be opened by pressure in the system exceeding the residual pressure. A second stop 33 is placed in the passage 11 on the opposite side of the residual pressure valve, against which the body 15, 16, 17 of said valve has to abut as a result of displacement thereof by means of an external device or an external pressurized fluid, said residual pressure valve being forcibly opened. Application in particular to refillable gas bottles.
