Definitions

  • the invention relates to an integrated pressure reducing valve for gas containers, which allows the safe parallel connection of gas containers forming a stack at higher than final pressure, as well as the direct filling of an empty gas container from a second container or stack of containers.
  • Integrated pressure reducers form part of a new device generation. They are positioned to supplant the existing traditional combination of a conventional valve with a pressure reducer. Unfortunately they cannot replace all of the current range because they do not allow the connection of several cylinders into a stack so as to assure significant flows.
  • FIG. 3 A conventional integrated pressure reducing valve for gas containers is shown in FIG. 3.
  • a valve comprises a filter 209, a high pressure valve 208, and an adjustable pressure regulator 204, connected in series between an inlet port 201 for connecting to the outlet of a gas container and an outlet connector 202 for connecting a consumer.
  • a high pressure gauge 212 is connected to the line between the filter 209 and the high pressure valve 208.
  • a filling port 210 is connected to the line upstream of the filter 209.
  • a residual pressure valve 211 may be added between the high pressure valve 208 and the filling port connection 210, and the adjustable pressure regulator 204.
  • the residual pressure valve 211 is useful to leave a positive pressure or higher than atmospheric pressure in the cylinder. This system is used for several reasons. Firstly it is to prevent the end-users from polluting the cylinder while trying to fill the tank with another gas. Within the framework of pure gas, e.g., this is extremely awkward. The second reason is to avoid introducing impurities (e.g. liquids such as water or beer) in the cylinder, which may happen in particular in the applications of CO 2 during a bad manipulation. Whichever liquid concerned, when placed in a cylinder of pure CO 2 it becomes an acid and begins oxidizing the cylinder. This can lead to a very dangerous situation when a full cylinder is bored by the acid.
  • impurities e.g. liquids such as water or beer
  • a vent relief valve 213 and a low pressure gauge 214 are connected to the outlet connector 202.
  • the vent relief valve 213 serves to depressurize the lower pressure chamber at the time of a malfunction of the pressure reducer valve 204.
  • a pressure of 200 or 300 bars exist.
  • the cylinder pressure reaches the downstream pressure chamber in which the pressure should not exceed 16 bars in certain application. If the pressure in this chamber becomes higher than 16 bars, the vent relief valve 213 opens thus avoiding any danger.
  • a high-pressure gas flow is connected to filling port 210.
  • the high-pressure valve 208 When the high-pressure valve 208 is opened, gas flow occurs through the filter 209 into the gas container, filling it up until the desired pressure is obtained.
  • the object of the invention is to safely allow the increase of flow rates in integrated pressure reducers, while respecting safety standards.
  • This is achieved by equipping an integrated pressure reducing valve with means which allow two bottling connections at different preselected pressures: a first auxiliary port after a first pressure reducing stage providing a preset pressure on the order of about 60 bar for the auxiliary port, and a second adjustable pressure reducing stage which provides the outlet port with a pre-selectable pressure on the order of about 0 to 10 bar.
  • the former may also be used as a connection port for connecting several cylinders in parallel.
  • the upstream pressure regulator is of the pre-set type, with the output pressure of the upstream pressure regulator preferably pre-set to about 60 bars.
  • downstream pressure regulator is of the adjustable type, with the output pressure of the downstream pressure regulator preferably adjustable from 0 to about 10 bars.
  • a preferred embodiment is the combination of a upstream pressure regulator of the pre-set type, with the output pressure of the upstream pressure regulator preferably pre-set to about 60 bars, with a downstream pressure regulator of the adjustable type, with the output pressure of the downstream pressure regulator preferably adjustable from 0 to about 10 bars.
  • auxiliary port is connected to the point of connection between the upstream pressure regulator and the downstream pressure regulator via a valve, preferably a check valve or a line valve.
  • Yet another advantageous embodiment comprises a filter placed upstream of the high-pressure valve.
  • a filling port is provided upstream of the upstream pressure regulator for filling a gas container connected to the inlet port.
  • a residual pressure valve is provided upstream of the upstream pressure regulator.
  • the first advantage of the solution according to the invention is that it is possible to directly connect a conventional pressure reducer to an auxiliary output at 60 bar, without the risk of damaging the poppet at full cylinder pressure.
  • the pressure reducer placed right before the connection ports removes the risk when filling an empty cylinder which has been connected directly to the full cylinder comprising the integrated pressure reducer.
  • RSV residual pressure valve
  • the gas container tap could be equipped with an integrated pressure reducing valve according to FIGS. 1 or 2.
  • a "wild" connection of a 300 bar cylinder in the cases of FIGS. 1 and 2 is still possible.
  • the consequence will be a marked deterioration of the poppets in the pressure reducers.
  • the anti-return RPV will prevent the filling of the cylinder.
  • gas container taps with a first simple reduction stage of 300 bars to 60 bars installed on cylinders but also on stacks allows a more complete use.
  • a pressure reducer with integrated pressure reducer could be used as a simple pressure reducer with an empty or a full cylinder.
  • the present invention will allow continuing to utilize the pressure reducer of the integrated cylinder after it is completely empty.
  • a gas container with a traditional pressure reducer can be connected to the auxiliary port, whereby it operates as an inlet, with the high pressure valve of the gas container closed.
  • the pressure reducer can be used for the reduction of pressure in containers which do not contain a pressure reducer.
  • a traditional pressure reducer to the auxiliary port (SP) to carry out be it either an shielding gas at the same time as a welding for protection gases (very useful for the pre-set pressure reducers) or a double use for all other gas.
  • This application is also possible and useful when the pressure reducer of the second stage has operating problems which are not related to the imperviousness of the valve.
  • the outlet of 60 bars could be used to directly supply either a pressure reducer with a flow of more than 30 m 3 /h or to supply a medium pressure network or even a central pressure reducer. This will allow to improve the safety, for the final user will no longer need to handle flexible devices or the connections of 300 bar.
  • FIG. 1 shows an integrated pressure reducing valve comprising two outlet connections according to a first embodiment of the invention.
  • FIG. 2 shows an integrated pressure reducing valve comprising two outlet connections according to a second embodiment of the invention.
  • FIG. 3 shows a conventional integrated pressure reducing valve.
  • FIG. 4 shows an auxiliary port of an integrated pressure reducing valve according to the invention connected to the auxiliary port of another integrated pressure reducing valve.
  • Fig. 1 shows an integrated pressure reducing valve comprising an inlet port 1 for connecting to the outlet of a gas container and an outlet port 2 for connecting to a consumer (not shown in the drawings). It further comprises an upstream pressure regulator 3 and a downstream pressure regulator 4 which are connected in series between the inlet connector 1 and the outlet connector 2.
  • the upstream pressure regulator 3 is arranged upstream of the downstream pressure regulator 4.
  • An auxiliary port 5 is provided at a point of connection 6 between the upstream pressure regulator 3 and the downstream pressure regulator 4.
  • Upstream pressure regulator 3 is of the pre-set type, with the output pressure of the upstream pressure regulator preferably pre-set to about 60 bars.
  • the maximum pressure at the point of connection 6 between the upstream pressure regulator 3 and the downstream pressure regulator 4 is thus limited to this value.
  • Downstream pressure regulator 4 is of the adjustable type, and the output pressure of the downstream pressure regulator 4 is preferably adjustable from 0 to about 10 bars. This pressure can be supplied to a consumer connectable to outlet port 2.
  • the auxiliary port 5 is linked to the point of connection 6 between the upstream pressure regulator 3 and the downstream pressure regulator 4 via a valve 7, e.g. a check valve or a line valve.
  • a valve 7 e.g. a check valve or a line valve.
  • the integrated pressure reducing valve further comprises a high pressure valve 8 for opening or closing the gas flow between inlet 1 and outlet 2.
  • a filter 9 is foreseen in the flow path between inlet 2 and high pressure valve 8.
  • a residual pressure valve 11 may be added between the high pressure valve 8 and the upstream pressure regulator 3.
  • a filling port 10 is foreseen at the junction of the gas container and the filter 9, preferably via a check valve 15 and an additional filling port filter 16.
  • the additional filling port filter 16 may be provided if the flow from the filling port 10 to the gas container shall be filtered, otherwise the filling can occur unfiltered.
  • Pressure gauge 12 is provided on the upstream side of high pressure valve 8 in order to allow a reading of the residual pressure in the gas container.
  • a further pressure gauge 14 is foreseen at the downstream side of downstream pressure regulator 4.
  • Vent relief valve 13 is also provided at the downstream side of downstream pressure regulator 4.
  • Fig. 2 shows an integrated pressure reducing valve 101-116 comprising mostly the same components as the embodiment of FIG. 1, wherein like references designate like components.
  • the filling port 110 is connected downstream of the high pressure valve 108, preferably via a check valve 115.
  • An additional filter is not necessary in this embodiment, because the gas flow from filling port 110 to gas container passes via the already foreseen filter 109.
  • the auxiliary port 105 is connected to the line at a point 106 between the upstream pressure regulator 103 and the downstream pressure regulator 104 via a check valve 107.
  • the filling port is connected to the auxiliary port of a full cylinder equipped with an integrated pressure reducing valve according to the invention.
  • the upstream pressure reducer of the integrated pressure reducing valve limits the pressure of the gas contained in the full cylinder to the predetermined level, e.g. 60 bar, which can be obtained by opening the auxiliary outlet valve.
  • the gas flow is passed directly to the filling port of the empty cylinder through a check valve. If a high-pressure valve is foreseen in the empty cylinder, of course, it needs to be opened in order to effect filling.
  • This invention announces a new generation of integrated pressure reducers which will be able to replace 95% of the current range of pressure reducers, which will clearly improve safety and will allow a more flexible use thereof.
