    摘要: An apparatus (100) for controlling the discharge of pressurized fluids from the outlet of a high pressure cylinder (110) containing toxic hydridic or flammable compounds is provided. The apparatus (100) contains a cylinder (110) for holding a pressurized fluid in an at least partial gas phase; a cylinder port body (114) threaded to the upper part of the cylinder (110) in a sealed position; a dual port head valve assembly (116) disposed within the cylinder port body (114), wherein a first port (130) is utilized to fill the cylinder with a pressurized fluid, and a second port in fluid communication with an outlet of the cylinder (122) to discharge the pressurized fluid; a gas flow discharge path (12 0) defined in part by the second port body and the outlet, and further including a restricted flow path (130) and a flow channel disposed upstream of the second port body, but wherein the gas flow discharge path does not include a restrictive element selected from the group of pressure regulators, check valves and restrictive flow orifices; and the restricted flow path (13 0) limits the flow rate of the gas discharged from the cylinder to 5,000 seem when the outlet of the cylinder (110) is exposed to an atmospheric condition.

    摘要: A treating gas supply system comprising treating gas supply piping (220) for supplying the treating gas from gas cylinder (210) to a treating unit and inert gas supply source (230) for supplying an inert gas to a gas supply piping, which treating gas supply system is adapted to during system operation wait ready while filling the interior of the gas supply piping with the inert gas, and to upon receiving of signal for treating gas use initiation (S) from the treating unit discharge by vacuuming the inert gas within the gas supply piping, charge the treating gas and initiate the supply of treating gas from a treating gas supply source, and to upon receiving of signal for treating gas use completion (F) from the treating unit terminate the supply of treating gas from the treating gas supply source, discharge by vacuuming the treating gas within the gas supply piping and charge the inert gas. Accordingly, in the nonuse of treating gas in the treating unit, the interior of the piping from the treating gas supply source to the treating unit is in the state of being filled with the inert gas to thereby attain preventing of any deposition within the piping during the nonuse period.

    摘要: A method and apparatus are presented for controlling the flow of gas from a source to a low- pressure device which is particularly useful for sampling high pressure gases. Examples are presented for the high-pressure dosing of an RGA. In one embodiment, the method isolates volumes of gases at high pressure, limits their pressure, and provides the gas at low pressure. In one embodiment the apparatus includes valves, flow restriction devices, and check valves, and can be used, for example, to either provide accurate and repeatable quantities discrete doses of gas from high pressure to low pressure or provide continuous dosing from high to low pressure. The apparatus and method are relatively insensitive to source pressure, and thus provide reproducible results over a range of source pressures.
