Definitions

  • the invention relates to a flushing block according to the preamble of claim 1.
  • Compressed gas cylinder connections are used to connect compressed gas cylinders to filling or dispensing systems, which are screwed onto the cylinder valve, for example, by means of a union nut.
  • a connecting line leads from the compressed gas cylinder connection to the filling or extraction system.
  • the invention is therefore based on the object of providing a flushing block which makes it possible to displace the process gases exclusively from the dead volumes of a fitting, in particular a cylinder valve.
  • the advantages achieved by the invention are that instead of a large number of fittings and connecting lines, only the bottle valve can be flushed in the form of an open ring flush.
  • the sampling line is shut off via a shut-off valve, so that no process gas can escape from the connected connecting lines and gas sampling fittings and no air or moisture can enter. It is advantageous here that during the flushing process no flushing gas enriched with moisture and process gas through the gas sampling fittings, e.g. B. pressure regulator or metering valve flows.
  • flushing gas outlets and inlets as well as the removal bore can be opened or closed via the flushing block, so that if necessary, for. B. if the empty gas cylinder contains the same process gas as the new one Pressurized gas cylinder to be connected, only the cylinder valve - on the other hand, however, the entire filling or dispensing system can also be flushed.
  • shut-off valves and the purge gas inlet and outlet are combined in one housing, the dead volume is reduced and operation is made easier. Contamination components such as particles and moisture are minimized, the purge gas consumption is reduced and the purge time when changing the gas cylinder is reduced.
  • Fig. 1 is a longitudinal sectional view of the flushing block according to the invention.
  • FIG. 2 shows a sectional illustration along the line II-II of FIG. 1.
  • Fig. 3 shows a device for process gases with a disposal bottle and a purge block according to the invention.
  • the flushing block 10 shown in FIGS. 1 and 2 consists of a connecting part 11 on which a union nut 12 is arranged.
  • the flushing block 10 is screwed onto the bottle valve 14 by means of the union nut 12, which can be placed against a flange 13 projecting radially from the connecting part.
  • the housing 15 of the flushing block 10 z. B. welded on.
  • Connection part 11 and housing 15 have a removal bore 16 which is connected to the outlet 17 of the cylinder valve 14.
  • the extraction bore 16 is connected to a process gas outlet 20 via a shut-off valve 19 arranged in the housing 15.
  • the housing 15 also has a purge gas inlet 21, which is connected to the outlet 17 of the cylinder valve 14 via a shut-off valve 22 arranged in the housing 15.
  • the connection is made by a tube 23 running in the extraction bore 16 and arranged in the housing 15 and a bore 24.
  • the outlet 17 of the cylinder valve is connected to a purge gas outlet 27 via a bore 25 branching off from the extraction bore 16 and a shut-off valve 26 arranged in the housing 15.
  • shut-off valves 19, 22 and 26 are shown as manually operated valves. It goes without saying and does not require a detailed description that these shut-off valves can also be operated automatically, for example pneumatically or hydraulically.
  • flushing block With the flushing block according to the invention, compressed gas cylinders with dangerous contents can be exchanged safely.
  • a flushing or inert gas flows in through the flushing gas inlet 21.
  • the shut-off valves 22 and 26 When the shut-off valves 22 and 26 are open, this passes through the bore 24 and the pipe 23 into the connection 17 of the cylinder valve 14.
  • the process gas in the dead volume there is mixed with the purge gas and flows through the bore 25 to the purge gas outlet 27.
  • the purging gas supply is interrupted by closing the shut-off valve 22.
  • the compressed gas bottle can then be safely exchanged for a freshly filled one.
  • shut-off valve 22 is arranged in the same horizontal plane over the corner to the shut-off valve 26 and on the same central axis of the tube 23.
  • the shut-off valve 19 is arranged in the intersection of the central axes of the shut-off valves 22, 26 perpendicular to these in the housing 15.
  • the purge gas inlet 21 and the purge gas outlet 27 emerge from the housing 15 on a common side 28.
  • shut-off valves 19, 22, 26 are advantageously arranged opposite the connection 12, 13, 17 of the bottle valve, while the shut-off valves 19, 26 are each arranged to the left or right of it.
  • the process gas flows perpendicularly to the shut-off valves 19, 22, 26 and passes from the flushing gas outlet or inlet 21 or 27 to a fitting, for example a pressure regulator.
  • a fitting for example a pressure regulator.
  • the Pressure gauges assigned to pressure regulators are advantageously arranged in the correct reading position.
  • the flushing block 10 has a flushing gas outlet 27, so that the flushing can be carried out in the form of an annular flush.
  • shut-off valves 22 and 26 are closed.
  • Process gas flows with the cylinder valve open via the extraction bore 16 and the open shut-off valve 19 to the process gas outlet 20.
  • FIG. 3 shows a device for the process gases with a purge block 10, the purge gas inlet 21 of which is connected to a purge gas bottle 31 via a pressure reducer 29 and a cylinder valve 30.
  • the connection 11, 12, 13 of the flushing block 10 is connected to the bottle valve 14 of the process gas bottle 18.
  • the flushing block With the process gas outlet 20, which exits in FIG. 3, for example on the upper side of the flushing block, the flushing block is connected to a gas extraction or filling system 32.
  • a pressure intensifier 36 can be arranged in the connecting line 35 arranged between the flushing block 10 and the disposal gas bottle 34, by means of the flushing gas pressure in the back pressure line as the flushing gas pressure decreases and the disposal bottle pressure increases is increased.
  • the disposal gas bottle can also be filled when the purge gas pressure decreases.
  • Another method consists in liquefying the process-purging gas mixture or atmosphere-purging gas mixture before its disposal by means of a disposal gas container.
  • the process purging gas mixture or atmospheric purging gas mixture can also be solidified using a chemical reaction process and likewise disposed of using a disposal gas container. In all disposal processes, toxic components can be neutralized using appropriate chemicals.
