Definitions

  • the invention relates to a pressurized gas container made of high-alloy chromium-nickel steel according to the preamble of claim 1.
  • Pressurized gas containers for the storage and distribution of ultra-pure gases are made of rustproof, high-alloy chrome-nickel steels. As a rule, these are compressed gas cylinders with a content between 5 and 50 liters, which are manufactured as a welded construction from a seamless or longitudinally welded cylindrical tube. This tube is closed by two welded-on floors. Before welding, the inner surfaces of the parts are easily accessible and can be used for later surface quality Experience the required mechanical pretreatment to the required roughness. The inner surfaces of containers made of such high-alloy chromium-nickel steels must have a quality which ensures that the purity and composition of the gases which come into contact with them are not affected. Therefore, these surfaces must be able to be polished electrolytically.
  • the threaded opening for the valve connection is the only access to the inside of the container.
  • the valve sleeve with the threaded opening for the valve connection is usually designed as a cylindrical neck piece which is welded into the upper bottom, as is shown, for example, by US Pat. No. 3,384,133. Because of the small thread opening, electrolytic polishing is very difficult and requires a great deal of effort, especially for bottles with a large content.
  • the invention is therefore based on the object to provide a valve sleeve for receiving the gas cylinder valve of compressed gas containers made of high-alloy chromium-nickel steels, which facilitates cleaning and electrolytic polishing of the inner surface of the container and at the same time ensures that the containers can be produced by cryoforming.
  • valve sleeve With the invention it is possible to remove the actual valve sleeve with its threaded opening from the container, whereby a large neck opening is free, through which the inner surface of the container can be easily cleaned and electrolytically polished.
  • a conical ground, purely metallic seal is preferred as the seal between the detachable part of the valve sleeve that is welded into the upper container bottom.
  • Other Sealing options are possible, however, for example a screw connection that seals using a cutting ring.
  • the invention also enables easy access to the interior of the container after it has been used, for example to check the quality of the surface.
  • the compressed gas container made of high-alloy chromium-nickel steel shown in FIG. 1 consists of a cylindrical tube 1, to which a lower base 2 and an upper base 3 are welded.
  • a foot part 4 serves as the container base, which can be attached to the container base by means of a threaded pin 5 welded to the lower base 2.
  • This design of the container base is particularly favorable since both the lower base 2 and the cylindrical tube 1 can deform freely and uniformly during cryogenic deformation.
  • a conventionally welded foot ring would hinder cryogenic deformation. Subsequent welding of a foot ring to the deformed container is prohibited because of the inevitable changes in material associated with it.
  • the valve sleeve fitted in the upper base 3 consists of a cylindrical neck piece 6 welded into the upper base 3 and an insert 7 which is detachably but gas-tightly connected to it.
  • the insert 7 contains the actual threaded opening for the gas cylinder valve 8, which is screwed into the insert 7 .
  • the insert 7 and the gas cylinder valve 8 can also be manufactured as one component from the outset.
  • the connection between the neck piece 6 and the insert 7 is designed as a conically ground sealing surface and represents a purely metallic seal. The required sealing pressure is applied by a union nut 9 which connects the neck piece 6 and the insert 7 to one another.
  • a neck ring 11 is pressed onto the upper base 3 at the same time by means of an elastic sealing ring 10.
  • the neck ring 11 can be made of metal or plastic. It is locked by a grub screw 12 directed towards the upper floor.
  • the neck ring 11 has a hexagonal recess corresponding to the contours of the union nut 9, which surrounds the lower part of the union nut 9.
  • the neck ring 11 locked by the grub screw 12 thus secures the union nut 9 against twisting and unintentional opening.
  • the purely metallic seal through a conically ground sealing surface between the neck piece 6 and the insert 7 represents a completely gas-tight connection. This applies both to normal operating conditions (200 bar internal pressure; ambient pressure) and to the Conditions during cryogenic stretching during production (approx. 600 bar internal pressure; 77 K). This type of sealing excludes any contamination of the gas content by contact with threads or other sealing elements.
