    摘要： A valve includes a valve housing (12) defining a fluid flowpath (14) therethrough, a valve element (16) located in the valve housing (12) and movable in the fluid flowpath (14) to regulate a fluid flow therethrough, and a valve actuator (34) operably connected to the valve element (16) to urge movement of the valve element (16) in the fluid flowpath (14). The valve actuator (34) includes an actuator housing (38), a volume of paraffin (46) located in the actuator housing (58), and an actuator rod (40) located in the actuator housing (38) and operably connected to the valve element (16), such that phase change of the paraffin urges movement of the actuator rod (40) between a first position and a second position, thereby moving the valve element (16) between a retracted position and an extended position.

    摘要： There is disclosed a diaphragm for a high pressure gas diaphragm valve. The diaphragm comprises a sealing body defining a sealing face for seating against a valve seat of the valve to close the valve; an outer flange for attaching the diaphragm to the valve, the outer flange defining a flange plane; and a deformable web that extends between the outer flange and the sealing body, the deformable web including a gusset that has at least one convolute portion. The gusset is deformable to allow the sealing body to move between a natural configuration in which the sealing body is on a first side of the flange plane, and a raised configuration in which at least part of the sealing body is on the opposing side of the flange plane, and wherein the at least one convolute portion biases the sealing body towards the natural configuration.

    摘要： An example apparatus includes a wall having an opening and a panel attached to the wall over the opening. The panel includes a shape-memory material (SMM). An example method includes bending the panel away from the wall via the panel at least partially changing from a first crystal phase to a second crystal phase. The panel bends away from the wall in response to a temperature of the panel increasing. The method further includes bending the panel toward the wall via the panel at least partially changing from the second crystal phase to the first crystal phase. The panel bends toward the wall in response to the temperature of the panel decreasing.
