Definitions

  • the invention relates to a compressed gas container, which in particular as a metal bottle or bottle bundle, which consists of several together by piping there are firmly connected individual bottles, is designed to accommodate flammable or toxic compressed gases, with a container body and a manual shut-off valve.
  • pressurized gas containers are sufficient in the prior art as a means of storage or known for the provision of compressed gases by means of known pressure gas container is made available to pressure gas end users.
  • the end user draws gas from the compressed gas tank until it is the supply in the compressed gas tank is running low. After the gas has been used, the Containers are regularly sent to a filling plant, from which the end user gets his gas.
  • the filling unit takes over the filling of the compressed gas tank and makes it available to the end consumer again.
  • individual bottles are designed Compressed gas containers often in so-called bottle or pallet bundles summarized.
  • Such bundles of bottles can, for example, 12 or more Include individual bottles.
  • the individual bottles of a bottle bundle are over one preferably brazed so-called manifold connected together, wherein the manifold forms the connection of the bottle bundle.
  • manifold forms the connection of the bottle bundle.
  • containers in bundles for flammable and toxic Compressed gases are each equipped with a gas cylinder valve that is in the open position is blocked.
  • Such a design of the individual bottles is quite complex and adversely affects costs and, above all, safe, continuous operation because, for example, with a 12-bottle bundle up to 12 valve seals could leak over time.
  • the container must be leakproof, particularly in the case of pressurized gas containers for gases which react in connection with air or water vapor, for example fluorine (F 2 ) in conjunction with water (H 2 O), which gives very aggressive hydrofluoric acid (HF) to be closed, since otherwise air can penetrate into the interior of the container with water vapor and cause corrosion there in connection with the residual gas. The corrosion creates a very annoying contamination inside the container.
  • gases which react in connection with air or water vapor
  • H 2 O water
  • HF hydrofluoric acid
  • shut-off valves Since the smallest particles in the valve seat of the container are so dirty Such shut-off valves can no longer be used with such containers tightly seal the required security. You will therefore be out regularly pulled and scrapped. While this is in terms of security required, but associated with high costs.
  • connection for mounting known for the connection of a gas container by means of which in a simple manner a filter and a flow restriction in the connection line of the gas container can be introduced.
  • the outlet connection is in the flow direction after a manual shut-off valve, by means of which the gas container can be closed.
  • the manual shut-off valve is directly with the container body without the interposition of further elements connected.
  • a pressure gauge arranged between the container body and the container-side first shut-off valve, which is a manual shut-off valve.
  • This measure can ensure that the containers are tightly closed after being separated from the sampling line become.
  • the pressure gauge can be designed so that it also has a slight Change in the residual pressure is readable.
  • the pressure gauge ensure that those containers are recognized in the filling plant, which were not tightly sealed, because then the absolutely necessary residual gas pressure has dropped to zero due to the leaky container valve.
  • the residual pressure indicator can be an inexpensive to produce indicator that only indicates that in the There is a residual pressure in the container, but it could also be caused by an additional pressure More comfortable manometer scale act as a gas level indicator.
  • the container mentioned at the beginning can also have a filter, which between the container body and the manual shut-off valve is arranged. Through the filter is achieved that dirt particles in the container are not in the valve seat of the Manual shut-off valve can get. This ensures that even dirty ones Containers can be closed tightly. It is thus through the invention possible, older containers, which have no residual pressure in the filling plant, and therefore not tightly closed, to be refilled and to the end user to provide. The resulting cost savings are considerably.
  • the filter can be a housing with a through opening have, in which a filter insert is interchangeably arranged.
  • the Housing sits tightly in a line by means of which the shut-off valve with the container body connected is.
  • a filter insert made of one has proven to be particularly advantageous Sintered material exposed.
  • a filter arrangement has also proven to be very advantageous highlighted, in which the filter insert in the housing on the one hand from the Shoulder of a cylindrical countersink in the through hole and on the other hand is held by a hexagon socket screw with a through hole.
  • a Such an arrangement is particularly space-saving, as a result of which it is installed in the line is facilitated.
  • the sintered material has proven to be particularly effective.
  • the Filter sits on the end of the line facing away from the pressure vessel and on its end facing away from the line is designed like a standardized device connection is.
  • the filter can be designed as a standard component, which is connected to the line so that it forms the line connection.
  • the filter in which the Line remote end has a cone, which to the connecting cone of Manual shut-off valve corresponds.
  • a further improvement of the invention is achieved in that the Side of the manual shut-off valve facing away from the compressed gas container is an additional one Electromagnetic shut-off valve is arranged, which is closed when de-energized is. In such an embodiment of the invention, it is safely achieved that the container is tightly closed after disconnection from the supply line is. Because the electromagnetic shut-off valve also closes the container if the manual shut-off valve is negligent not closed.
  • a container designed as a bottle bundle 1 has 12 bottles, which with a manifold 2 are connected.
  • the line 2 points to her the bundle 1 facing away from a bundle connection 7.
  • a manual shut-off valve 5 is arranged between the bottle bundle 1 and the bundle connection 7 .
  • a filter 4 is arranged between the bottle bundle 1 and the manual shut-off valve 5 with a pressure gauge 3 connected.
  • an electromagnetic shut-off valve 6 is arranged in the collecting pipeline 2. The electromagnetic shut-off valve 6 is closed when de-energized.
  • the bottle bundle 1 is connected by means of the bundle connection 7 to a removal line (not shown) installed at the end consumer. After the content of the bottle bundle 1 is almost used up, the manual shut-off valve 5 is closed. Then the sampling line up to the manual shut-off valve is freed of any residual toxic gas with an inert, non-toxic gas such as N 2 or by applying a high vacuum. The bundle connection is then removed from the sampling line and another bottle bundle is clamped onto the sampling line.
  • a removal line not shown
  • the arrangement according to the invention also makes it possible to switch off a almost empty bottle bundle and the connection of a filled bottle bundle automatically without interrupting the gas supply to the sampling line make.
  • a control can be provided, by means of which when replacing the container, the electromagnetic shut-off valve 6 of the almost empty bottle bundle 1 is de-energized and the electromagnetic shut-off valve 6 of the filled bottle bundle 1 is supplied with current.
  • the electromagnetic shut-off valve 6 of the almost empty bottle bundle 1 By switching off the power or by applying current to the electromagnetic shut-off valve 6 of the almost empty bottle bundle 1 closed and the electromagnetic shut-off valve 6 of the filled bottle bundle 1 opened.
  • After de-energizing of the electromagnetic shut-off valve 6 of the almost empty bottle bundle 1 can Bundle connection 7 of the almost empty bottle bundle 1 from the extraction line be separated.
  • the filter 4 is at the end of the collecting pipe 2 arranged, which is connected to the manual shut-off valve 5.
  • the Filter 4 has a housing 11 which is tightly connected to the manifold 2.
  • a through opening 16 is arranged, which is axially extends completely through the filter housing 11.
  • a filter insert 12 made of sintered material.
  • the filter insert 12 sits on the one hand on the Schuiter a cylindrical depression of the through opening 16 and is on the other hand by an Allen screw 13 with a through hole held. To remove the filter insert 12 from the filter housing 11, the Allen screw 13 is screwed out of the through opening 16.
  • the filter insert 12 at the end of the filter facing away from the collecting line 2 4 of the through opening 16 can be removed.
  • the filter housing 11 has a cone.
  • the Cone corresponds to a trained at the port 15 of the manual shut-off valve 5 Pipe end.
  • the filter housing 11 is fixed with a union nut 14 the port 15 of the manual shut-off valve 5 connected.
  • the filter 4 Since the filter 4 is firmly connected to the manifold 2, it is also located when filling the bottle bundle 1 in the manifold 2 Filter insert 12 flows through when filling the bottle bundle 1 with gas, whereby the filter cartridge 12 is cleaned again and again.
