摘要:
Die Erfindung betrifft ein Kraftfahrzeug mit einem Drucktank, in welchem ein Energieträger zur Versorgung zumindest eines letztlich dem Antrieb des Fahrzeugs dienenden Energiewandlers unter hohem Druck in der Größenordnung von 300 bar und mehr speicherbar ist, welcher Drucktank eine Sicherheits-Entlastungseinrichtung aufweist, welche bei Vorliegen eines kritischen Zustande, insbesondere bei hohen bspw. bei einem Brand auftretenden Temperaturen, zumindest eine Teilmenge des gespeicherten Brennstoffs aus dem Tank entweichen lässt. Das Kraftfahrzeug weist zumindest eine Anschlussmöglichkeit für eine externe Fluiddruckquelle sowie einen durch eine angeschlossene Fluiddruckquelle betätigbaren Manipulator auf, welcher mit Betätigung ein öffnen der Sicherheits-Entlastungseinrichtung bewirkt.
摘要:
A cryogenic tank system includes a plurality of heat exchangers for heating an interior volume of a storage container. Heat transfer to the interior volume of the storage container by the plurality of heat exchangers pressurizes the interior volume of the storage container. The system further includes a valve assembly mounted to the storage container and positioned substantially within the storage container. The valve assembly includes an inlet portion and an outlet portion. The outlet portion is positioned outside of the storage container, and the inlet portion is positioned within the storage container. The inlet portion is sealable by a fail-closed powered sealing mechanism.
摘要:
A modified vacuum actuated valve assembly and sealing mechanism is provided for improved sub-atmospheric flow stability characterized by the absence of delivery pressure spikes and flow excursions. The valve assembly includes a non-stationary thermoplastic seat and a stabber. The stabber is characterized by a top portion having a circular periphery designed to mechanically engage and disengage with an inner sealing surface of the thermoplastic seat. The sealing surface is coined to eliminate surface irregularities contained therein, thereby producing a relatively smooth coined mating inner sealing surface for the circular top portion of the stabber. The valve assembly also includes a modified bellows capable of fine tuning the delivery pressure of the valve assembly.
摘要:
A gas supply device, the device comprising a body which comprises a cylinder housing for receiving a gas cylinder; a valve assembly; and a pressure regulator arranged to operatively interact with the valve assembly to regulate the pressure of the gas exiting the cylinder housing in use. A cavity is located downstream of the pressure regulator for housing atomisable liquid.

In order to improve storage tanks for cryogenic liquid gases, a full integrity spherical storage tank(80) is proposed, said tank(80) comprising: -an inner tank(82) of cryogenic steel; -an outer tank(83) of cryogenic steel; -a support structure(81); and -an outlet pipe(84) communicating with the interior of the inner tank(82).
摘要:
A storage device for the storage of a medium, in particular of a pressurized medium, such as, for example, liquefied natural gas, having a single-walled or multi-walled storage container, is described. According to the invention, in the upper region of the storage space (3) a multiplicity of nozzles (6) are provided, these nozzles (6) being arranged in such a way that the medium discharged from these produces a downwardly directed curtain of mist (8), the mist curtain (8) being configured such that between its outer wall and the inner wall of the storage space (2) at least one convection roll (9) can be formed.
摘要:
The present invention provides a fluid filter utilizing a polymeric membrane supports by metallic screens contained in a housing. The supports have apertures through which fluid can pass. The metallic supports are created such that they have at least one surface substantially free from burrs, so as not to damage the membrane. This smooth surface is in communication with the polymeric membrane. One or more indexing protrusions can be added along the circumference to restrict the relative movement between the supports, and to align the apertures of the two supports.

A high pressure storage and delivery system having a fail-safe vacuum actuated valve is provided. In particular, through the innovative design of the vacuum actuated check valve, the system can accommodate up to three times the volume of product in similar size cylinders.
摘要:
An apparatus (100) for controlling the discharge of pressurized fluids from the outlet of a high pressure cylinder (110) containing toxic hydridic or flammable compounds is provided. The apparatus (100) contains a cylinder (110) for holding a pressurized fluid in an at least partial gas phase; a cylinder port body (114) threaded to the upper part of the cylinder (110) in a sealed position; a dual port head valve assembly (116) disposed within the cylinder port body (114), wherein a first port (130) is utilized to fill the cylinder with a pressurized fluid, and a second port in fluid communication with an outlet of the cylinder (122) to discharge the pressurized fluid; a gas flow discharge path (12 0) defined in part by the second port body and the outlet, and further including a restricted flow path (130) and a flow channel disposed upstream of the second port body, but wherein the gas flow discharge path does not include a restrictive element selected from the group of pressure regulators, check valves and restrictive flow orifices; and the restricted flow path (13 0) limits the flow rate of the gas discharged from the cylinder to 5,000 seem when the outlet of the cylinder (110) is exposed to an atmospheric condition.
