The head includes an inflation channel, which connects the filling channel to the body and includes an inflation non-return valve preventing the air from exiting the body. An inflation organ is movably mounted on the inflation channel to permit opening of the inflation non-return valve.

An emergency response containment vessel for a cylinder includes a vehicle frame and a sealing container carried by the vehicle frame. The sealing container includes a barrel body including an opening, a locking module, and a cover module. The locking module includes a fixed seat surrounding the barrel body and adjacent to the opening, a ring seat connected rotatably relative to the fixed seat between lock and unlock positions, and a driving device driving the ring seat to rotate. The ring seat includes a plurality of alternating blocks and notches and an annular groove. The cover module includes a connecting arm pivotably connected to the fixed seat and a cover connected to the connecting arm, removably covering the opening, and including a plurality of engaging portions removably received in the annular groove and respectively aligned with and misaligned with the notches when the ring seat is at the unlock and lock positions, respectively.

An insulation arrangement configured to cover a vessel containing a liquified gas is provided. Embodiments include an insulation arrangement including an aerogel composition and a vapor barrier, where the insulation arrangement reduces heat transfer between the ambient environment and the liquified gas. Other embodiments include an insulated clamping device configured to connect a vessel to a framework and a connection system including the insulated clamping device, where the vessel includes the aforementioned insulation arrangement.

A valve for use in a tank vessel that includes a valve housing configured to fit into a threaded vent opening of the tank vessel and a sleeve weldment coupled to the valve housing. The sleeve weldment includes a first end configured to protrude into an interior volume of the tank vessel, and the first end is thermally balanced with the interior volume of the tank vessel. The valve also includes a valve plunger configured to be installed within the sleeve weldment. The valve plunger includes a valve bottom configured to seal an opening between the valve bottom and an interior opening of the sleeve weldment. The valve also may include a cam configured to force the valve plunger into the interior of the tank vessel to break the seal between the valve bottom and the interior opening of the sleeve weldment.

An automatic gas shutoff system for protecting the occupants of a home, apartment, RV, vehicle, etc. from dangerous levels of carbon monoxide. The automatic gas shutoff system generally includes one or more carbon monoxide detectors, a control unit, and a gas shutoff valve under the control of the control unit, so that the gas supply to a malfunctioning appliance can be shut off in the event it is creating dangerous levels of carbon monoxide within a protected space. The shutoff valve may have a manual reset feature that requires a problem condition to be repaired before the valve is manually reset to allow normal gas flow to resume.

This invention relates to a method and a system for calculating in real-time the duration of autonomy of a non-refrigerated tank containing natural gas comprising a liquefied natural gas (LNG) layer and a gaseous natural gas (GNG) layer. This invention also relates to a system for calculating, in real time, according to the method of the invention, the duration of autonomy of a non-refrigerated tank, as well as a vehicle comprising an NG tank and a system according to the invention.

A method for supplying a consumer with a cryogen from a storage vessel, with the following steps: a) introducing part of the cryogen from the storage vessel into a volume that can be closed off, b) closing off the volume by first closing a supply valve arranged between the volume and the consumer, and then closing an inlet valve arranged between the storage vessel and the volume, c) vaporizing the cryogen in the volume so as to subject the volume to a pressure which is higher than a pressure prevailing in the storage vessel, and d) discharging the vaporized cryogen from the volume to the consumer when the consumer has a load requirement by opening the supply valve, wherein, when the supply valve is open, the inlet valve is opened as soon as the pressure in the volume falls below the pressure prevailing in the storage vessel.

The invention relates to a pressure vessel (1) with an interior chamber (30), in particular for storing hydrogen, comprising a vessel wall (12) which has or consists of a composite material unit (14, 22, 26) with reinforcing fibers (16) and a thermoplastic plastic matrix (18), wherein the composite material unit (14, 22, 26) is arranged and configured such that the reinforcing fibers (16) can be removed as continuous fibers, in particular non-destructively, so that the composite material unit can be reused.

A fueling station dispenser for distributing a combustible gas that is lighter than air, and that includes electrical and gas handling sections in the same frame. A vapor barrier in the cabinet blocks fugitive gas that may be present in the gas handling section from entering the electrical section. According to most applicable codes, by isolating combustible gas from the electrical section gives it a Class I, Division 2 designation. Which eliminates the need to seal or air purge the electronics section as this designation allows for electronics that under normal intended operating conditions do not generate an arc with sufficient energy to initiate combustion.

The present disclosure is directed to a method and system for detecting activation of a pressure relief device connected to a storage tank containing a pressurized gas. The method includes calculating a pressure relief device release rate based on a set of inputs, wherein the set of inputs includes at least one of a storage tank volume, a pressure relief set point, an orifice size of the pressure relief device, a gas density, and a reseat point for the pressure relief device. The method further includes monitoring the pressure within the storage tank and calculating a differential pressure reading over time, comparing the differential pressure reading over time to the pressure relief device release rate, and detecting a pressure relief device activation based on the comparison result.
