    摘要: The present invention relates to an actuator (30) for operating a valve in a fluid line comprising: an actuating member (15) with an actuating element (8) for transferring a force to the device, wherein the actuating member (15) is mounted to move between a first and a second position, a spring (10) for storing energy and for moving the actuating member (15) from its first to its second position by means of this energy in order to thereby move the actuating element (8), lock means for locking the actuating member (15) in its first position, and release means for releasing the actuating member (15) in order to allow the actuating member (15) to move from the first to the second position, wherein the release means are pressure operated and adapted to be in contact with the fluid line and wherein the release means release the actuating member (15) when the pressure in the fluid line exceeds a threshold.

    摘要: A safety valve (10, 10B) comprising an internal volume in which a piston (30) is slidably housed, which piston (30) is destined to sub-divide the internal volume into two chambers, of which a first chamber (27) communicating with an inlet (21), with an outlet (22) and with a discharge (23) for a fluid, and a second chamber (28) communicating with the outlet (22) downstream of pressure reducing means (24) of the fluid between the first chamber (27) and the outlet (22), a first stem (32) fixed to the piston (30), which extends into the first chamber (27) and comprises an obturator organ (35) destined to cooperate with a valve seating (34) in order to at least partly close communication between the first chamber (27) and the discharge (23) following a displacement of the piston (30) in a volume-reducing direction of the second chamber (28), and in order to open the communication following a displacement of the piston (30) in the opposite direction, and a second stem (36) fixed to the piston (30), which second stem (36) extends into the second chamber (28) and is slidably inserted in an opening (37) of a delimiting wall (38) of the second chamber (28).

    摘要: In one embodiment, a flow control valve includes a valve body having an inlet, an outlet, a flow passageway coupling the inlet to the outlet, and a cavity with first and second chambers. The valve further includes a hollow piston disposed in the first chamber and a seal separating the first and second chambers. The seal has a section within the piston that is exposed to the fluid in the first chamber. The section of the seal defines a first effective area. The valve also includes a biasing member configured to urge the piston, and a reference pressure passageway in fluid communication with the inlet and the second chamber. The valve can further include a piston seat that has a second inner effective area at least approximately equal to the first inner effective area.

    摘要: L'invention propose un dispositif de vanne cryogénique comprenant un corps de vanne (1) dans lequel circule un fluide cryogénique et un clapet (2) disposé dans le conduit et relié à une tige de commande (3) pour manoeuvrer le clapet entre une position de fermeture et une position d'ouverture de manière à contrôler le débit du fluide cryogénique. Le dispositif comprend en outre un actionneur pneumatique (4) comprenant une chambre (41) renfermant un piston (42) en liaison avec la tige de commande (3), la chambre (41) étant alimentée avec un gaz de commande pour positionner le piston dans une position déterminée. L'actionneur est fixé au corps de vanne par l'intermédiaire d'une chambre (51) interposée entre l'actionneur (4) et le corps de vanne (1) de manière à découpler thermiquement l'actionneur du corps de vanne pour maintenir la température de l'actionneur et, par conséquent celle du gaz du commande, à une température intermédiaire entre la température du corps de vanne et la température ambiante. La chambre (51) est en surpression afin d'empêcher des entrées externes et d'évacuer les éventuelles fuites dans le dispositif.
