Definitions

  • lid or cover locking devices of the above mentioned type for instance the so-called Uhde- Bredtschneider locking device as disclosed in the VDI- Periodical 104 (1962), page 479, are relatively difficult to install and to remove.
  • FIG. 3 shows in section the pretensioning device for the metallic sealing ring.
  • FIG. 4 illustrates on a somewhat larger scale than FIG. 1 a section taken along the line IVIV of FIG. 1 while the segment bolt has been omitted.
  • FIG. 6 illustrates a portion of an installed closing device as seen in the direction of the arrow C of FIG. 1.
  • FIG. 7 shows a segment bolt by itself.
  • FIG. 8 shows the bolt of FIG. 7 as seen in the direction of arrow D.
  • the cover or lid closing device for high pressure containers is characterized primarily in that a plurality of bolts distributed over the circumference of the cover are rotatably arranged and have one half of their circumference extend into corresponding semicylindrical recesses in the cover and in the container head, the bolts being so designed that in a certain positions of rotation they will lock the cover to the container head.
  • the bolts are provided with annular teeth having a different height over their circumference. These teeth engage corresponding semiannular grooves of likewise different height in the recesses on the cover and on the container head.
  • Such segment bolts have, after the lid or cover has been put on the container, only to be turned by a certain angle, for instance 180, in order to lock the cover to the container head.
  • a self-locking closing device can be realized by providing in a conical recess at the edge of the inner end face of the cover a metallic sealing ring with a cylindrical outer surface and a conical inner surface. This metallic sealing ring may, after the cover has been locked, be pulled against the conical recess and the cylindrical wall of the container head by means of pretensioning screws extending through the cover for purposes of presealing the closing device.
  • This presealing operation by means of the pretensioning screws may be facilitated by interposing thin metallic foils which will plastically deform in response to the tightening of the screws.
  • the metallic sealing ring is loaded to such an extent that it will sealingly engage the conical recess in the inner end face of the cover and also the cylindrical wall of the container head whereupon the pretensioning screws can be loosened again.
  • the present invention also yields the advantage that standardized closure parts can be used and a reduced flange reinforcement on the container head will suffice so that a corresponding saving in material and weight will be realized.
  • the metallic sealing ring is in view of its cylindrical outer surface prevented from jamming or tilting.
  • a high pressure container having a cylindrical opening, a cover inserted into said opening for closing the same and having its peripheral surface provided with semicylindrical first recesses, said pressure container having its inner periphery within the region of said opening provided with semicylindrical second recesses, and a plurality of bolts distributed over the circumference of said cover and circumferentially provided with means operable in response to turning about their axes to engage said first and second recesses so as to interlock said cover and said container.
