摘要： A method of functionally testing a pressure actuated regulator (10). The pressure actuated regulator includes a valve member (14) arranged to open a valve aperture (16), and a control pressure volume (24) in which a control pressure is set to act on the valve member. The method includes applying a force to the valve member, and taking measurements representative of the pressure of fluid in the control pressure volume and of the mass flow rate of the fluid into the control pressure volume while the force is being applied to the valve member. The method also includes isolating the control pressure volume and allowing a pressurised fluid in the control pressure volume to leak out of the control pressure volume, and taking measurements representative of the pressure of fluid in the control pressure volume while the fluid leaks out of the control pressure volume.

摘要： A device (1) for controlling the flow of a fluid through a conduit (3) from an upstream side (8) to a downstream side(10). The device includes a housing (4) having one or more valve apertures (6) through which the flow of fluid is selectively controlled. A valve member (12) is mounted on the housing and arranged to move reciprocally to selectively open and close the one or more valve apertures. A seal (20) is arranged at or beyond a position the valve member reaches when the one or more valve apertures are all closed. The device also includes a resilient member (26) that acts to bias the seal towards the valve member.

摘要： A device (1) for controlling the flow of fluid through a conduit from an upstream side (3) to a downstream side (5). The device includes a housing (4) with a wall (6) having valve apertures (8) through which the flow of fluid is selectively controlled. A valve member (10) is mounted on one side of the wall of the housing and is arranged to move reciprocally to selectively open and close the valve apertures. A removable insert (12) is mounted on the opposite side of the wall of the housing from the valve member. The removable insert is arranged to cover some of the valve apertures.

摘要： A device for controlling the flow of a fluid through a conduit from an upstream side of the device to a downstream side of the device. The device includes a valve aperture (30), a cylindrical mounting member (24) on the downstream side of the valve aperture, a valve member (26) on the outside of the cylindrical mounting member that moves reciprocally to open and close the valve aperture, a control volume (44) defined between the cylindrical mounting member and the valve member, an arrangement (8) for introducing a control pressure into the control volume, and a seal (34) between the outer surface of the cylindrical mounting member and the inner surface of the valve member that substantially seals the control volume. The valve member is acted on by the pressure of the upstream side (PI) and the control pressure (P4) so as to be moved by the difference between these pressures.

摘要： A device (1) for controlling the flow of a fluid through a conduit from an upstream side (6) of the device to a downstream side (8) of the device. The device includes a housing (16) defining a valve aperture (18) and a mounting member (12) arranged on the downstream side of the valve aperture. A valve member (14) is movably mounted on the mounting member and is arranged to selectively open and close the valve aperture to control the flow of fluid. A soft seal (36) is arranged on the housing for substantially sealing the valve aperture when the valve member contacts the housing. The soft seal is located downstream of a convex curved surface of the housing which is shaped to separate the flow of fluid through the valve aperture away from the surface of the housing such that the fluid does not impinge directly on the soft seal.

摘要： A device (1) for controlling the flow of a fluid through a conduit (3) from an upstream side (8) to a downstream side (10). The device includes one or more valve apertures (6) through which the flow of fluid is selectively controlled. A valve member (12) is arranged to move reciprocally to selectively open and close the one or more valve apertures. The device includes a stop (18) for arresting the travel of the valve member arranged at or beyond a position the valve member reaches when at least some of the one or more valve apertures are open. The valve member includes an end portion (13) arranged to come into contact with the stop when the valve member reaches or passes the position at which at least some of the one or more valve apertures are open and a body portion (9).
