Definitions

  • the invention relates to a pressure vessel according to the features of the preamble of claim 1.
  • the state of the art, as described in the WO 2021/099542 A1 described, a pressure vessel and a method for producing a pressure vessel are known.
  • the pressure vessel comprises a vessel body with a vessel bottom arranged at a lower end and formed in one piece with the vessel body, an end piece arranged at an upper end of the vessel body and formed in one piece with the vessel body and having an opening, a connection geometry arranged on the outside of a wall surrounding the opening of the end piece, wherein the wall forms a connection with the connection geometry which is designed to be coupled to a corresponding further connection in a media-tight manner, a fastening structure for a valve formed on the inside of the wall surrounding the opening of the end piece and an overpressure protection device arranged in an overpressure opening of the end piece or an overpressure opening of the vessel body.
  • a gas cylinder for axial sampling is known, which has two auxiliary outlets on the side of the cylinder neck to accommodate a test valve and a pressure relief valve.
  • a C02 capsule and a device for automatically filling the capsule are described.
  • a one-way valve is provided which is mounted on the 12 gr. CO2 capsule, the 12 gr. CO2 capsule with the one-way valve, which is connected to the one-way valve and a filling device for filling the 12 g CO2 capsule with liquid carbon dioxide gas.
  • a pressure bottle for a paintball marker is known.
  • a device for use in paintball includes a modified pressure bottle with a valve assembly that is "integrally" mounted in its neck and is independent of the connection structure for connecting the bottle to a paintball marker WO2021137206 A1 shows a pressure vessel valve with two outlet openings.
  • the invention is based on the object of specifying a novel pressure vessel.
  • a pressure vessel has a vessel body. At an upper end of the vessel body, an end region is formed integrally with the vessel body. This end region formed integrally with the vessel body can also be referred to as an end piece. The end region has an opening.
  • the pressure vessel also has a fastening structure for a valve formed on the inside of a wall surrounding the opening of the end region.
  • two outflow openings are formed in the wall surrounding the opening of the end region, in particular opposite one another.
  • the pressure vessel for example a compressed gas vessel, enables the integration of the valve or a valve function into the end area and in particular a direct media-tight coupling of the pressure vessel with another connection, for example a connection of an application.
  • this enables a medium in the container body, such as a gas, such as carbon dioxide, to flow out sideways.
  • the medium flows through the valve and then through the two outflow openings in the wall and into the application.
  • the solution according to the invention is therefore particularly suitable for applications in which such a lateral outflow is required.
  • the solution according to the invention achieves a smaller overall height because the valve can be or is arranged almost completely in the container body. For example, only a collar-shaped upper section of a valve body of the valve protrudes from the container body, which lies sealingly against one end face of the wall of the end region.
  • the pressure vessel also has, in particular, the valve, which is arranged in the end region, in particular is screwed into it.
  • the valve is designed, for example, as a check valve.
  • a valve body of the valve has in particular exactly one passage opening, which is formed radially from an inner side towards an outer side of the valve body. This enables the valve body to be manufactured easily.
  • the valve body is particularly stable because it has only a single passage opening, thus avoiding additional weakening caused by multiple passage openings.
  • the valve body can therefore be formed, for example, with less material expenditure and/or from a different, in particular more cost-effective, material, for example from aluminum or brass.
  • the valve may have a plurality of such passage openings, each of which is formed radially from the inside towards the outside of the valve body.
  • the passage opening or the respective passage opening in the valve body is positioned at the level of the outlet openings in the end area. This ensures short flow paths between the passage opening in the valve and the two outlet openings.
  • the passage opening or the respective passage opening can also be positioned at a height offset from the height of the outlet openings in the end area.
  • the passage opening opens into a distributor groove formed all around the outside of the valve body and/or an inner opening edge of the respective outflow opening is arranged on a groove base of a circumferential distributor groove formed on the inside of the wall of the end region. This ensures an even distribution of the medium flowing out of one passage opening in the valve body to the two outflow openings in the wall of the end region and thus an even flow of the medium out of both outflow openings.
  • the distributor groove is designed to be correspondingly wide or a connecting channel is provided between the passage opening or the respective passage opening and the distributor groove or another fluidic connection is provided between the passage opening or the respective passage opening and the distributor groove.
  • the fastening structure has in particular an internal thread arranged on the inside of the wall.
  • the valve body has an external thread corresponding to the internal thread of the fastening structure.
  • the valve body When screwed into the internal thread, in particular completely, i.e. up to a predetermined end position, the valve body is arranged in the area of the opening of the end region, protrudes from the opening into the end region, rests against the end region in a media-tight manner and has a receiving opening.
  • a sealing tappet is arranged in the receiving opening, which in a closed position closes the passage opening in a media-tight manner, i.e. closes it either directly or indirectly in a media-tight manner, and in an open position releases the passage opening.
  • the valve has in particular a support element connected to the valve body or formed on the valve body and a spring element arranged within the valve body, which is supported with a first end on the support element and with an opposite second end on the sealing tappet, wherein the spring element is tensioned, in particular compressed, when the sealing tappet moves from the closed position to the open position.
  • valve body can be dimensioned significantly weaker in terms of its material thickness and material quantity.
  • At least one seal is arranged between the valve body and the end region.
  • a seal is arranged above and below the passage opening between the valve body and the end region.
  • the seal above the passage opening creates a The medium is prevented from flowing out of the opening in the end area upwards out of the container body.
  • the seal below the passage opening prevents the medium from flowing between the wall of the end area and the valve body and thus past the valve in the direction of the outflow openings in the wall of the end area.
  • two seals are also arranged between the valve body and the sealing tappet, for example in the form of an O-ring or a shaft seal.
  • One seal is arranged above the passage opening to prevent the medium from flowing out of the receiving opening upwards, so that it is ensured that the medium flows out laterally exclusively via the two lateral outflow openings.
  • the other seal is arranged below the passage opening. This prevents the fluidic connection between the passage opening and the area of the receiving opening that is fluidically connected to the interior of the container body when the sealing tappet is in the closed position and releases it when the sealing tappet is in the open position.
  • the passage opening is fluidically connected to the receiving opening and the sealing tappet closes the receiving opening and thus also the passage opening in a media-tight manner in the closed position and releases the receiving opening at least in sections in the open position and thereby also releases the passage opening.
  • the passage opening is thus closed in a media-tight manner by means of the sealing tappet in the closed position, in particular indirectly, by closing the receiving opening and thus the passage opening fluidically connected to it in a media-tight manner.
  • the support element and/or the valve body has an inflow opening. This allows the inflow of a medium located inside the container body, at least when the sealing tappet is in the open position, into the receiving opening in the valve body and thus, at least when the valve stem is in the open position, allows the medium to flow in the direction of the passage opening.
  • the valve body has a pressure equalization opening. This enables the valve tappet to be moved into the open position and back into the open position, particularly when the support element is in a closed configuration, with pressure equalization taking place between an area of the receiving opening below the sealing tappet and the interior of the container body.
  • the container body has in particular a container base arranged at a lower end and formed in one piece with the container body.
  • the one-piece design of the entire container body including the container base and end area means that particularly high pressure stability is achieved with little effort, in particular with little material expenditure, since connections, for example weld seams, which represent weak points, are avoided.
  • the container body has in particular a connection geometry arranged on the outside of a wall surrounding the opening of the end region, for example an external thread, a locking arrangement or a quick-release fastener, wherein the wall with the connection geometry forms a connection which is designed to be coupled to a corresponding further connection in a media-tight manner.
  • the connection geometry for example a so-called ACME thread
  • the valve can be omitted as a separate component.
  • connection geometry at the end area and thus at the pressure vessel due to the design of the connection geometry at the end area and thus at the pressure vessel, reliable and improved media tightness can be achieved, which results in particular from a reduction in the number of joints and their sealing compared to the solutions known from the prior art with a separate valve. In addition, assembly effort is reduced.
  • a seal provided in the prior art for sealing the valve against the pressure vessel in particular a so-called O-ring, can be omitted, which also results in a reduction in the number of individual parts and a reduction in costs.
  • the valve Due to the integration of the valve into the pressure vessel and the formation of the external thread at the end area, the valve no longer has to be made of brass.
  • both the pressure vessel i.e. the vessel body with the vessel base and the end area, and the components of the valve are made of aluminum. This has the advantage that particularly low costs can be achieved and that at least all components responsible for the media tightness are made of the same material with the same thermal expansion coefficient, thus avoiding different expansions and the resulting leaks when temperatures change.
  • the components of the valve and the pressure vessel can also be easily and completely recycled.
  • the valve can be made of brass or another material, for example.
  • the vessel body and the end region are manufactured together from a material blank in a roll forming process. Furthermore, the The fastening structure for the valve and in particular the connection geometry is produced by means of machining and/or forming, in particular during the roll forming process, and/or applying material and/or other suitable processes in the area of the end area. Furthermore, the two outflow openings are formed in the wall of the end area. The valve is then fastened in the area of the opening in the end area.
  • the pressure vessel can be manufactured particularly easily and with high quality using the roll forming process.
  • the production of the fastening structure and the fastening of the valve are also particularly easy, reliable and can be implemented at low cost.
  • the pressure vessel can, for example, also have an overpressure safety device.
  • this overpressure safety device is arranged in the valve.
  • this overpressure safety device is arranged, for example, in an overpressure opening formed in the bottom of the vessel. If the bottom of the vessel is designed accordingly, for example with a corresponding recess, this enables an integrated arrangement of the overpressure safety device without it protruding beyond an outer edge of the pressure vessel. This increases protection against mechanical damage to the overpressure safety device.
  • the installation space required to accommodate the pressure vessel in an application can be reduced and assembly of the pressure vessel in the installation space is simplified.
  • the overpressure protection device comprises, for example, a bursting disc, which is secured, for example, with a screw comprising a vent bolt.
  • a design of the overpressure protection device is particularly simple, cost-effective and reliable.
  • the overpressure protection device is designed for a trigger pressure of 250 bar.
  • any other trigger pressure values are also possible.
  • the rupture disc is fluidically coupled to the interior of the pressure vessel and is, for example, secured at the edge by the screw held within which a vent bolt is formed or arranged. If the trigger pressure is exceeded, the rupture disc is mechanically destroyed and releases a fluidic connection between the vent bolt and the interior of the pressure vessel, so that fluid inside the pressure vessel, for example gas, can escape.
  • the overpressure opening comprises an internal thread that corresponds to an external thread of the screw, into which the screw is screwed.
  • the internal thread is produced by machining.
  • the internal thread can also be produced in a forming process, for example a roll forming process, during the formation of the container base. Alternatively, other processes for producing the internal thread are also possible.
  • the overpressure opening in the vessel base is created by means of machining and/or forming, in particular during the roll forming process, and/or applying material and/or other suitable processes and then the overpressure safety device is attached to the overpressure opening.
  • the creation of the overpressure opening and the attachment of the overpressure safety device are particularly simple, reliable and can be implemented at low cost.
