Abstract:
A vapor pressure regulation system includes a vessel including a vessel wall that defines an enclosure, and a temperature adjustment mechanism coupled to the vessel. A heat transfer between the temperature adjustment mechanism and the vessel is adjusted based on at least a vapor pressure within the vessel to facilitate regulating the vapor pressure within the vessel.
Abstract:
A blanket installation method includes: a transporting step of transporting a blanket unit (1), in which a blanket (2) and a transport jig (3) are integrally coupled, between an inner tank (60) and an outer tank (50) of a double shell structure tank in a suspended condition; and a mounting step of mounting the blanket unit (1) on a shell plate of the inner tank (60). The transport jig (3) is formed by attaching a blanket fixing pin (34) to a jig main body (3A) through pin coupling. The blanket (2) is held at the blanket fixing pin (34).
Abstract:
The invention relates to a valve for a pressurized fluid cylinder comprising a member for manually controlling a flow-regulating member, a sensor for detecting the position of the member for manually controlling the regulating member, a data acquisition, storage, and processing member, and a display for information relating to the fluid flow and/or pressure imposed by the regulating member and/or the valve use mode, wherein when the manual control member is disposed in an intermediate position between two respective adjacent values of the flow and/or pressure of the fluid allowed to pass from the upstream end to the downstream end, the data acquisition, storage and process member is designed to suppress the display information.
Abstract:
A fill valve (200) adapted for use with a pressurized fluid container includes a fill port (112) configured to be in fluidic communication with the pressurized fluid container and a fill valve member (201) configured for selectively blocking the fill port (112) and configured to be non-openable after the fill valve member (201) has been moved to a blocking position that substantially closes the fill port (112). The fill valve member (201) includes a valve member body (210) and a break-away head (220) joined to the valve member body (210) by a breakable neck (228). The breakable neck (228) is configured to break when the fill valve member (201) is moved to a substantially fully closed position in the fill port (112).
Abstract:
A portable gas cylinder is disclosed which includes a gas cylinder including an upper portion having a valve port and an annular mounting collar surrounding the valve port, a handle assembly including a housing having a body portion configured to mate with the upper portion of the gas cylinder, a pair of diametrically opposed gripping handles extending upwardly from the body portion and a central aperture providing access to the valve port, wherein an annular retention channel is formed in an undersurface of the housing, extending about the periphery of the central aperture for receiving the mounting flange of the gas cylinder, and a blocking ring for securing the mounting flange of the gas cylinder within the retention channel of the handle assembly.
Abstract:
This invention concerns a system and equipment for supplying high pressure gas using special hydraulic oil which comprises a mobile hydraulic pressurization unit also known as an “HPU”, mounted on a truck which is connected to a semi-trailer comprising pressurized gas cylinders, where a pump, which activates a mobile hydraulic pressurization unit is coupled by a coupling device to the engine of the truck itself, and with pressurized gas cylinders with open upper and lower ends, comprising a single valve positioned at the upper end of the cylinders, which send the pressurized gas to a client, a single valve positioned at the lower end of the cylinders which both send hydraulic oil to the cylinders from an oil reservoir, and return the hydraulic oil to a hydraulic oil reservoir from the cylinders.
Abstract:
There is provided a protection structure for a gas cylinder assembly comprising a gas cylinder body and a valve. The gas cylinder body includes a base and a neck to which a proximal end of the valve is connectable in use. The protection structure comprises first and second structural sections, the first section being connectable to the valve such that the second section is spaced from the valve by the first section. Further, in use, the second section is arranged to transfer impact forces to the first section, and the second section is arranged to deform with respect to the second section in response to said impact forces to reduce the peak impact force on the valve.
Abstract:
A liquefied gas system and method can supply gas from a liquefied gas container more efficiently by using an external stabilizing device. The liquefied gas is located under its own vapor pressure in the lower portion of the container. As the vapor is withdrawn from the container at ambient pressure, the liquid evaporates at an equivalent rate to account for the decrease in pressure. The stabilizing device surrounding the liquefied gas container efficiently transfers the ambient external heat to the liquid thus allowing more liquefied gas to be vaporized.
Abstract:
A valve assembly comprising a valve body and a lever for actuating the valve, the valve body comprising at least one device having a visual display, wherein the at least one device is located such that, when the lever is in a closed position, at least a portion of the visual display is located behind the lever. The lever may include an opening or window for viewing the visual display when the lever is in the closed position, or the lever may be transparent.
Abstract:
Device for storing and releasing fluids at nearly constant pressure, the fluids including a gas and a liquid, includes an assembly of substantially identical reservoirs (1), where the reservoirs include: a portion containing the gas (G) and a portion containing the liquid (L), an element (23) of separation between the gas and the liquid in the reservoir (1), an inlet orifice (36) and an outlet orifice (36) for the gas, an inlet orifice (35) and an outlet orifice (35) for the liquid. The reservoirs (1) have a cylindrical outer envelope (100) made up of at least one metal tube (101) of the type of those used for gas pipelines and oil pipelines, for which: the external diameter is more than 32 inches (813 mm); and the ratio of the length thereof to the outer diameter thereof is greater than 8.
