摘要:
A system and method for loading liquid gases into a container includes supplying substance to a pump simultaneously with the evacuation of the container for cooling the pump down during evacuation and starting the pump motor when the pump has reached a low temperature determined in accordance with the pressure of the substance storage tank. An analyzer for detecting the presence of contaminants is coupled to the evacuation line in fluid communication with the substance removed from the cylinders. Cavitation during the loading operation is detected by monitoring the flow of substance from the pump. A plurality of containers of differing sizes are loaded simultaneously on the same manifold. An isolation valve is provided in the manifold for terminating flow of substance to smaller containers when the smaller containers are full while permitting substance to continue to flow to larger containers coupled to the manifold.

A device intended to feed a gaseous high-pressure fluid to a platform supported on a frame on which is located a pressure source, said device comprising a rotating joint unit including two fluid conduct members mounted in relative rotational relationship to said platform along the geometrical axis around which said platform is rotating, one of said members being connected to fittings usable for feeding said fluid and located on said platform. The other member is intended to feed said pressure source, the fluid conduct member which is intended, in the joint unit, to be connected to said pressure source is connected to the latter by a releasable connecting member. The coupling of said member depends on the fluid feeding required by the user or by said fitting usable for the fluid feeding and mounted on said platform.
摘要:
An apparatus and method for the recovery of propane vapors during propane cylinder refueling. The apparatus includes a separate recovery cylinder adapted to receive vapors that may be created during the refilling of propane cylinders. The recovered vapors may be used in the refilling of other cylinders during a subsequent refilling operation.
摘要:
A mobile fill station for filling propane cylinders by weight and volume. There can be up to three cabinets in the system wherein any one of the cabinets can have a beam scale with a hydraulic automatic stop device to stop filling automatically as the total weight of the cylinder reaches a pre-set scale limit. Any one of the cabinets can also include a flow meter to stop filling when an operator monitors an amount on the meter and manually stops propane flow. The cabinets could also include an electronic scale with a digital indicator where filling stops automatically as the total weight of the cylinder reaches a pre-set computer limit.
摘要:
A process for automatic filling with products, particularly of gas into gas cylinders, utilizes electronic comparison of the data stored in a data carrier located on the tank with the actually measured weight of the tank makes it possible to determine the degree of residual filling in the tank as well as to ascertain whether the tank weight is too low which, under certain circumstances, can give rise to safety risks and, in response, to either remove the tank from the filling process or else to fill it.The process and the device function fully automatically, so that it is possible to save personnel costs.
摘要:
A system for continuously filling a plurality of cylinders with a precise concentration of a vaporized liquid component blended into a gas is disclosed wherein the concentration of the liquid component of the resultant final blended mixture is continuously analyzed, and immediately adjusted, during the filling process. Due to the constant analysis and adjustment, any error in the concentration of a component is typically realized before the concentration is outside an acceptable range. The inventive system allows for a large number of cylinders to be accurately and quickly filled with the compressed, final blended mixture.

A plurality of pressure vessels are filled with acetylene gas by an apparatus which has a gas delivery conduit with a plurality of delivery connections. A drive mechanism moves pressure vessel supports from a loading station to locations where each pressure vessel is located at and conducted to a respective gas delivery connection. The gas delivery conduit is stationary, but its mountings permit horizontal movement to avoid damage to the apparatus if the supports are accidentally moved when the pressure vessels are attached to the delivery connections. When the gas delivery conduit is displaced more than a certain amount from its normal stationary position, power to the drive mechanism is automatically cut off. The supports for the pressure vessels are oriented to house the pressure vessels at an inclination which maintains them steady. The disclosed drive mechanism has two pneumatic cylinders for driving the supports along a slide of a fixed structure.

A pressurized fluid container filling system is disclosed comprising a first support platform for supporting a plurality of pressurized fluid containers for evacuating, a vacuum supply assembly for connecting a vacuum source to the fluid containers supported on the first platform and having at least one supply line for connection to the container valves, a second support assembly for supporting a plurality of pressurized fluid containers for filling, a pressurized fluid assembly for supplying pressurized fluid to the containers supported on the second platform and having at least one supply line for connection to the container valves, and a valve-clamp assembly interconnecting a container valve to the vacuum and fluid-supply assemblies, the valve-clamp assembly having a quick-disconnect valve for rapid connection and disconnection to the fluid supply line and vacuum supply line to permit flow when connected to the supply line and to close off flow when disconnected from the supply line, a valve-seat assembly for press-sealing connection to the nozzle of a container valve, and a releasable clamp for clamping the nozzle of a container valve into sealing engagement with the valve-seat assembly.
摘要:
The invention relates to an installation for filling gas containers (5) comprising at least one gas-container (5) filling system (2) comprising at least one gas-distribution device and connection means allowing the said device (1) to be connected fluidically to several containers (5) so as to fill the said containers (5) simultaneously with gas, for example a mixture of NO and of nitrogen. The gas-distribution device comprises a main body (1) with an internal gas-distribution chamber (3), a gas inlet orifice (11) fluidically communicating with the internal chamber (3) so as to allow gas to enter the said internal chamber (3) via the said inlet orifice (11), and several outlet orifices (12) fluidically communicating with the internal chamber (3) so as to allow gas to be discharged from the said internal chamber (3) via the said outlet orifices (12). The outlet orifices (12) are angularly distributed in the internal chamber (3).
