摘要:
A fail safe container and container insert are disclosed. A flexible container insert may convert energy from a catastrophic event, including but not limited to collisions, accidents, impacts, pressure container failures or explosions such as detonations, or other catastrophic incidents, into a stretching of an internal structure of a fail-safe container insert to minimize or prevent failure of the container insert and/or the container. The stretchability of the container insert may accommodate both temperature and shape changes to protect a container, including but not limited to a pressure vessel, from rupture or other failure. Accordingly, a container insert may be considered self-healing in that it may absorb the effects of catastrophic events to prevent failure, may return to a generally previous condition, and/or may seal or otherwise reduce or minimize breaches when they do occur.

A compression system is disposed in a container and shipped to a location having a supply of natural gas. The compression system connects to the natural gas supply, compresses gas from the supply, and provides compressed gas to a consumer. The container, which can be a standardized ISO shipping container, is fitted with removable vents at designated locations. Strategic positioning of compression system components in combination with the removable vents allows for ready access to the compression system for repair and maintenance.

Dispositif de purge automatique d'un réservoir de gaz sous pression comprenant une vanne (5) de décharge ayant une extrémité amont destinée à être mise en relation avec une réserve de gaz sous pression d'un récipient (1) et une extrémité aval destinée à être mise en relation avec une zone d'évacuation de gaz, ladite vanne (5) de purge étant déplaçable entre un état «fermé» obturant le passage de gaz entre les extrémités amont et aval et un état «ouvert» autorisant le passage de gaz entre les extrémités amont et aval, le dispositif comportant un volume (2, 3) de réserve stockant un réactif (4) à une pression déterminée, la pression du réactif (4) dans le volume (2, 3) de réserve étant sensible à la température, notamment lors de conditions d'incendie, ledit du volume (2, 3) de réserve étant relié à la vanne (5) de purge pour sélectivement commander le déplacement de ladite vanne (5) de purge de son état «fermé» vers son état «ouvert» lorsque le réactif (4) subi une variation de pression déterminée, caractérisé en ce que la vanne (5) de purge comprend une entrée sensible à la pression reliée au volume (4) de réserve, ladite entrée actionnant sélectivement le déplacement de la vanne (5) de purge de son état fermé vers son état ouvert en réponse à une augmentation de pression déterminée dans le volume (4) de réserve
摘要:
The present invention is a tank suitable to contain high pressure fluids, especially for compressed natural gas used for automotive purposes. The tank has a discoid shape to be easily placed on board of vehicles. The tank comprises a sealed internal core and an external coating made through a twisted coats fiber wrapping of composite material with a very high mechanical tensile resistance. According to some executive variants, the tank internally comprises a reinforcing structure made up of a plurality of elements welded in contact with the internal surface of the core.

A protective device (100) for gas cylinders is provided that protects the body of the gas cylinder from damage, is light, does not affect the required heat exchange from the environment to the liquified gas within the gas cylinder and renders the gas cylinder assembly easier to stack for safe storage. The protective device in accordance with the principles of the invention comprises a top part (105) and a bottom part (110) forming a cavity within which the gas cylinder is placed. In accordance with an illustrative embodiment of the invention, the top part and bottom part are both made of synthetic materials and are interconnected during assembling process by a standard functional clipping device. These clippings may be broken in order for the protective device to be removed, allowing visual inspection of the gas cylinder without damaging the gas cylinder in the removal process.

A system and method for withdrawing gas from a plurality of vessels is provided. The system is characterised by each vessel having a respective actuated valve associated with the vessel to selectively permit the withdrawal of gas from the vessel. Each vessel also has a sensing means to determine when it is substantially empty. A control means is arranged to receive a signal from a vessel when that vessel becomes substantially empty, and to close that vessel's actuated valve.

A fluid flow safety device comprises a body having an inlet end for connection to a fluid supply and an inlet passageway (8, 48, 103) which leads to a selective fluid flow sensor chamber (9, 49, 115) having a sealing means (10, 50) which encircles the outlet orifice (11, 51) of smaller cross section than that of the sensor chamber, said outlet orifice leading from the sensor chamber into a pressure chamber (12, 52) within the body leading to an outlet. Between the inlet end of the sensor chamber and the sealing means is a tapered section (13, 117), wherein the bore of the sensor chamber decreases in diameter as it nears the sealing means. A sensor chamber shield (120) may encircle the sensor chamber by forming , defining and separating the internal length of the sensor chamber passageway from that of the inlet or any other passageway. A ball (16, 56, 119) in the sensor chamber moves between the inlet passageway end of the sensor chamber and the outlet orifice, to form a seal with the sealing means when flow through the sensor is above a predetermined value. Within the pressure chamber is a movable piston (20, 60, 131) in sealing contact with it to increase or decrease the volume of the pressure chamber. Movement of the movable piston form a rest position fully towards the sensor chamber will deny a seal to made between the ball and the sealing means. The movable piston may be a primary valve mechanism which forms a seal between the inlet and outlet passagways. The movable piston may include an indicator mark visible only when the pressure in the pressure chamber is avove a predetermined value. Embodiments for LP gas include separate use of sensor chamber or movable piston with or without primary valve.
摘要:
Generally there is described herein two versions of a thermally conductive porous inner structure for a tank. In the first embodiment a closed tank (10) is accessed through an orifice and an injection tube is inserted to spray a coat of adhesive on the inner surface. Next a foil ribbon is fed through a tube (40) into the tank, allowing it to coil and fold therein until the tank is filled. When the adhesive (38) hardens a thermally conductive mesh-like structure results. In the second embodiment a tube is inserted through the tank opening and a mixture of ribbon segments and quick setting adhesive are injected. These segments fill the tank with a porous structure to create a mesh-like thermal insert. With either embodiment, a reinforcing liner can also be installed through the orifice. Resin, plastic, or fiberglass/resin mixture can be sprayed into the tank to form the liner, or plastic can be inserted and centrifugally molded within the tank. In the manufacturing or remanufacturing process, the position of the injection tube is controlled in coordination with the weight of the tank, gradually being withdrawn as the tank weight increases. Once the desired weight is reached, the injection is terminated and the injection tube is withdrawn.

Process for recovering industrial gas bottles in a pressure-resistant sealed enclosure by destroying the shut-off valve to empty them completely, recovering the contents and cleaning the bottle for re-use, and automatic or non-automatic devices for implementing said process. The invention relates to the industrial waste recovery and re-use sector, the process according to the invention being innovative in that industrial gas bottles are emptied in the sealed pressure-resistant chamber (11) by means of outside-operated hydraulic shears (4), causing the shut-off valve (9) to rupture by deformation, thereby enabling the contents to be drained off and analyzed before transfer for re-use or destruction, and the bottle (1) to be processed for re-use or destruction.
