Abstract:
Embodiments of the present invention relate to compressed gas storage units, which in certain applications may be employed in conjunction with energy storage systems. Some embodiments may comprise one or more blow-molded polymer shells, formed for example from polyethylene terephthalate (PET) or ultra-high molecular weight polyethylene (UHMWPE). Embodiments of compressed gas storage units may be composite in nature, for example comprising carbon fiber filament(s) wound with a resin over a liner. A compressed gas storage unit may further include a heat exchanger element comprising a heat pipe or apparatus configured to introduce liquid directly into the storage unit for heat exchange with the compressed gas present therein.
Abstract:
The container has an end wall portion (12) provided with an access opening (A) in which is affixed a nozzle (B) in the form of a metallic tubular insert (20) comprising: a mounting portion (21) fitted in the access opening (A); a nozzle portion (22); an external peripheral flange (23), having an annular face (23a) in which are adapted annular sealing means (30); and a nut (40) adapted around the mounting portion (21) and pressing the end wall portion (12) against the annular sealing means (30) of the annular face (23a) of the flange (23). The end wall portion (12) may be preformed in a single piece with an annular wall portion or fixed to the latter, and provided, in both constructions, with a median opening (13,51) which defines the access opening (A) of the container.
Abstract:
A method of assembling a first part (1) with a second part (2) having at least one crimping lip (4), a crimping anvil (3) and a crimping groove (9) designed to accept an edge (10) that is to be crimped belonging to the first part, in which method the edge that is to be crimped is introduced into the crimping groove and magnetic crimping is performed by applying to the crimping lip a magnetic field that is designed to bend the crimping lip over and close the crimping groove onto the edge that is to be crimped, characterized in that the crimping anvil has at least one inclined portion.
Abstract:
A gas pressure regulator is provided that includes a body defining a front portion and opposed side portions. A first gas pressure indicator is mounted to a lower end of the front portion of the body, and a second gas pressure indicator mounted to an upper end of the front portion of the body, wherein the first gas pressure indicator and the second gas pressure indicator are stacked in a vertical configuration. Additionally, a pressure adjustment knob is mounted to one of the side portions of the body in one form of the present disclosure.
Abstract:
A storage system, including an outer casing having an evacuated inner volume; a vessel for storage located within the outer casing and having a plurality of protrusions distributed on an outer surface thereof; and a plurality of filamentary strands spanning the inner volume, wherein at least some of the plurality of protrusions are essentially tangentially contacted by a plurality of the filamentary strands to secure the vessel in six degrees of freedom relative to the outer casing.
Abstract:
This invention is directed to pressure vessels in which the strength necessary to withstand the pressure exerted by a contained fluid under intended operating pressures is provided by a dry filamentous over-wrap.
Abstract:
The present invention relates to a fire resistant pressure vessel in which the inclusion of fire resistance does add appreciably to the overall weight of the vessel over a similar vessel that is not fire resistant.
Abstract:
A safety device for containers pressurized with gas safeguards the gas side of the working chamber of hydraulic accumulators. A relief apparatus (2) reduces an elevated gas pressure in the container (3) caused by heat. The relief apparatus (2) is a component loaded under the influence of a shear force or compressive force. The shape change of the component under the influence of heat on the safety device (1) in a space (5) closed to the outside occurs such that a fluid-conducting connection (6) from the inside of the container (3) to the outside in the direction of the surroundings is enabled.
Abstract:
An apparatus and method for constructing a cryogenic storage tank (700) having a welded inner tank (702), an outer shell (704) surrounding the welded inner tank (702), a concrete foundation (728) comprising a raised portion (752), a plurality of cellular glass blocks (734) positioned directly on top of the raised portion (752) of the concrete foundation (728), a leveling course of concrete (736) poured on top of the uppermost layer of the plurality of cellular glass blocks (734), and a mounting apparatus (718) affixed to the concrete foundation (728), where the welded inner tank (702) is positioned on top of the leveling course of concrete (736) and the outer shell (704) is affixed to the mounting apparatus (718) at locations around the periphery of the outer shell (704).
Abstract:
A liquefied gas tank includes an inner tank (2) that stores liquefied gas and is disposed so as to be capable of self-standing on a floor surface (F), and an outer tank (3) that is covered over the inner tank (2) and is supported by an upper face portion (2a) of the inner tank (2). The outer tank (3) is configured to be capable of sliding on the upper face portion (2a) of the inner tank (2) in response to expansion and contraction in the horizontal direction of the inner tank (2), and to be capable of moving in response to expansion and contraction in the vertical direction of the inner tank (2). A ceiling portion (3a) of the outer tank (3) that is placed on the upper face portion (2a) of the inner tank (2) is not fixed to the upper face portion (2a) of the inner tank (2), and the inner tank (2) and the outer tank (3) are configured to be capable of sliding in the horizontal direction relative to each other. The outer tank (3) includes an expansion and contraction mechanism portion (33) that is disposed along the lower outer circumference thereof.
