Abstract:
The invention relates to a device (10) for storing pressurized gas, comprising a plurality of storage tanks (11) which each have a tank wall (12) which encloses a hollow space (15) intended for the storage of the pressurized gas. The storage tanks (11) are connected to each other and have at least one connection for introducing and/or discharging the pressurized gas. To configure the storage tanks (11) such that they are as stable as possible each storage tank (11) has preferably one covering layer (16) which is positioned on the tank wall (12) at least in partial areas of every storage tank (11). In addition, to allow for the individual adjustment of the geometrical structure of the device (10) to the spaces available and to the quantity of gas to be stored, every storage tank (11) has an upper part (20) which is joined to the tank wall (12) and the storage tanks (11) are or can be connected with each other in a modular manner by means of these upper parts (20). The pressurized gas is withdrawn from the storage tanks (11) through a flow channel (24) provided for in the upper parts (20) which communicate with the hollow space (15) of each storage tank (11) via a through hole (26). The individual upper parts (20) are joined by means of connecting elements (23) which are introduced into corresponding openings located in the upper parts (20).
Abstract:
The present disclosure provides a pressure vessel (10) (sometimes known as a composite overwrapped pressure vessel or "COPV") comprising carbon fiber (20) (such as carbon fiber (20) filaments) wrapped around a tank liner (30).
Abstract:
Die vorliegende Erfindung betrifft einen Druckbehälter für kryogene Flüssigkeiten. Der Druckbehälter besteht aus einem Liner aus einer Metalllegierung mit kubisch-flächenzentrierter Gitterstruktur oder einer Titanlegierung mit hexagonaler oder gemischt hexagonal/kubisch-raumzentrierter Gitterstruktur. An dem Liner liegt eine Armierung aus faserverstärktem Kunststoff an, wobei die Matrix des faseverstärkten Kunststoffs im kryogenen Bereich eine hohe Bruchdehnung besitzt.
Abstract:
The present invention relates to an independent vessel tank system for storing liquid gas. The system comprises a first tank member (1), a second, cylindrical tank member (2) connected to the first tank member (1) and a third tank member (3) connected to the second tank member (2), where the first, second and third tank members (1, 2, 3) provide a tank device for the liquid gas. A first supporting device (5) is provided between the third tank member (3) and a hull of the vessel, for supporting the weight of the tank device. A second supporting device (4) is at least partially provided along the periphery of the tank device, for supporting the tank device to the hull of the vessel.
Abstract:
A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The flexible pressure vessel has a pressure relief device comprising a reduction in thickness of one end cap at a predetermined location. When subjected to overpressure it fails at the predetermined location. Other pressure relief devices include: a projecting member on the vessel surface, a weakened section of the passageway, a weakening or an absence of braiding material or hoop winding at a predetermined location on the vessel surface or along the passageway, a weakening or spreading of fibers in either the reinforcing panels or the flexible blankets covering the vessel.
Abstract:
A composite pressure vessel and method of manufacture. A composite pressure vessel comprises a multi-component mandrel that is integrated into the vessel, thereby becoming a permanent part of the pressure vessel, and comprises a cylinder and dome ends. Dome ends are made from custom molds with a fiber reinforced polymer. Components of the mandrel may be pieced together with a joining resin. The mandrel comprises a permeation barrier coated on the inside by spraying with elastomer resin, for example. Filaments are wound onto the mandrel, allowing any length of cylinder section to be made for the pressure vessel.
Abstract:
An orientation independent delivery device (100). The delivery device (100) includes a gas chamber, a delivery chamber, a gas cell (110), and a delivery aperture (112). The gas chamber includes a gas-side rigid portion (102) and a gas-side flexible barrier (104). The gas-side flexible barrier (104) is sealed to the gas-side rigid portion (102). The delivery chamber includes a delivery-side rigid portion (106) and a delivery-side flexible barrier (108). The delivery-side flexible barrier (108) is sealed to the delivery-side rigid portion (106) and is oriented adjacent to the gas-side flexible barrier (104). The gas cell (110) is coupled to the gas-side rigid portion (102) of the gas chamber. The gas cell (110) increases a gas pressure within the gas chamber to expand the gas-side flexible barrier (104). Expansion of the gas-side flexible barrier (104) applies a compressive force to the delivery-side flexible barrier (108) allowing a delivery material to escape from the delivery chamber.
Abstract:
A gas storage tank is described comprising at least one inflatable bellows (20) confined within a casing (22) and preloaded to extend in length when the gas pressure within the bellows (20) exceeds a predetermined value above the ambient pressure as gases are blown into the bellows (20). The casing (22) has diverging sides (24) guiding the extending bellows (20) and is closed off by a moveable end wall (26) held against the extending bellows (20) by a spring (28), the end wall (26) having adjustable dimensions matching and closing off the widening opening of the diverging sides (24) as the bellows (20) extends against the spring (28).
