To provide a gas filling apparatus with high handleability and safety. A gas filling apparatus including: a filling mechanism for carrying a gas through gas carrying pipes while measuring flow rate of the gas from a gas supply source (accumulator); a filling hose connected to the gas carrying pipe and having a filling nozzle at an end of the filling hose; and an attachment sensor (nozzle attachment detecting portion) for outputting a detection signal after detecting that the filling nozzle is attached to a filling port of an in-vehicle tank, wherein filling gas to the in-vehicle tank by the filling mechanism becomes possible after the detection signal is inputted to the filling mechanism from the attachment sensor. The gas filling apparatus may further include: a pressure gauge for measuring a pressure in the in-vehicle tank; a thermometer for measuring ambient temperature; and a target pressure calculating means (comparing means) for calculating a pressure in the in-vehicle tank when filling up the in-vehicle tank or filling preset amount of the gas is finished before filling gas to the in-vehicle tank based on a capacity of the in-vehicle tank and the measured pressure in the in-vehicle tank and the measured ambient temperature; wherein the filling mechanism stops carrying the gas to the in-vehicle tank when the pressure in the in-vehicle tank reaches the target pressure.

Tankstutzeneinheit (100,110) für ein Fahrzeug, umfassend einen Tankstutzen (142,165), einen Durchflussweg (140) und ein Rückschlagventil (28), wobei der Tankstutzen (142,165) für einen vorgegebenen Maximaldruck eingerichtet ist der höher ist als ein zulässiger Betriebsdruck eines im Fahrzeug angeordneten Druckspeichersystems und die Tankstutzeneinheit (100,110) ein Sperrventil (SV,120) aufweist, wobei das Sperrventil (SV,120) im Durchflussweg (140) zwischen dem Tankstutzen (142,165) und einem Auslassbereich der Tankstutzeneinheit (100,110) angeordnet ist und dazu eingerichtet ist, das im Fahrzeug angeordnete Druckspeichersystem gegen Druckanstieg über seinen zulässigen Betriebsdruck hinaus zu schützen. Tanksystem für ein Fahrzeug umfassend eine Tankstutzeneinheit (100,110), Druckleitungen (66) und zumindest einen Druckspeicherbehälter (S).
摘要:
A measuring system for the charged amounts in a pressure container using pressure and volume comprising: an information acquisition device that can collect information on volume and maximum charging pressure of the pressure container; first and second automatic valves, a reference container, a pressure sensor and a temperature sensor that are connected to a gas line between a storage tank and a charging nozzle; a control part that calculates the charged amounts through engineering calculations with pressure detected by the pressure sensor, temperature detected by the temperature sensor, and basic information on the pressure container and that calculates changes in temperature and volume of the pressure container to calibrate for the charged amounts, determine safety of the pressure container, and convert the calibrated charged amount to a sum of money; and a display part that receives the calculated information from the control part and inform it to a user.

A storage tank assembly for the storage of cryogenic liquids comprising a first outer tank and a second inner tank, the first and second tanks being spaced apart from one another to form an insulation space, the storage tank assembly further comprising a cryogenic liquid delivery system including an eductor located within the second inner tank so as to entrain cryogenic vapour during filling of the inner tank with cryogenic fluid.
摘要:
A filling valve for LPG tanks with automatic stop device, comprising a valve body (2) which can be coupled to a tank (3) and forms a channel (5) for connecting the inside and the outside of the tank (3) and has the particularity that it comprises, in the channel (5), an obturator (6) with a first hermetic piston (7) and a second hermetic piston (8) which are operatively interconnected and act respectively on an inlet seat (11) and on an abutment (30) for connection to the inside of the tank (3). There is also provided a valve device which is actuated by the level of the liquid contained in the tank (3) and allows to position the second piston (8) on the connection abutment (30) when the preset level is reached inside the tank (3).
摘要:
A method and system for tank overfill prevention comprising the steps of supplying fluid to the interior of the tank by means of a dispenser, measuring the dispenser pressure P d and flow rate α, determining at equal time increments 8t a number of quantities representing tank pressures from the said dispenser pressure and flow rate measurements, and deriving from the said determined quantities representing tank pressures, another quantity representing the rate of increase of tank pressure with respect to time, comparing the quantity thus obtained with a preset critical value, and shutting off the fluid supply, if this said quantity exceeds the said preset critical value and if the said flow rate α is less than a preset critical value.
摘要:
A fuel storage system is provided for storing dimethylether (DME), a blend including DME, or other similar highly volatile fuel at a vehicle. The fuel storage system including a main storage tank, an expansion tank, a fuel filling receptacle configured to receive a fuel filling nozzle of a filling station, and a valve arrangement having at least a normal operating setting and a fuel filling setting. The valve arrangement in the normal operating setting provides a fuel passage between the main storage tank and the expansion tank, and the valve arrangement in the fuel filling setting both provides a fuel passage between the fuel filling receptacle and the main storage tank and prevents fuel flow between the main storage tank and the expansion tank. The fuel storage system is configured to mechanically prevent disconnection of the fuel filling nozzle from the fuel filling receptacle unless the valve arrangement is in the normal operating setting. A corresponding method, as well as a further example embodiment of the fuel storage system, are also provided.
