摘要:
Each container in a bank of containers is individually charged with a gas in the order of the highest residual pressure remaining in the containers at the time charging is initiated. Gas withdrawal from the containers begins with the container at the lowest beginning pressure.
摘要:
A fuel regulator for a propane appliance wherein a preset spring biased valve member such as a ''''tire valve'''' is disposed in series between an inlet from a propane source and a plurality of separate outlets and is controlled by a diaphragm regulator so that gaseous fuel may be supplied to each of the plurality of separate outlets at a constant pressure.
摘要:
A device for reducing evaporation of volatile organic compounds (VOC) during filling of a substantially liquid petroleum product into a storage and/or transportation tank (18) via a down pipe (14), wherein the down pipe (14), which has a non-constricted flow-section, is provided with an inlet (22) for gas at its upper portion, the inlet (22) being arranged to enable inflow of gas due to the underpressure being formed in the upper portion of the down pipe (14) when the petroleum product flows down through the down pipe (14).
摘要:
A low pressure gas storage system comprising an annular anchor ring, a granular bed within the ring, a flexible membrane of gas storage chamber positioned above the bed, and a flexible membrane of air chamber encompassing the gas storage chamber and exerting pressure thereon; and a plurality of flexible, radially-extending restraining means positioned against and over the air chamber to exert a predetermined pressure thereon.
