  • the dome cover arrangement is particularly advantageous for the dome cover arrangement to be set up or to prevent the cover from being opened and/or moved, in particular by the actuator, out of the first rotary position through the interaction of the encompassing element, in particular the clamp, and the recess , as long as a force is exerted on the lid, in particular by the hollow seal and/or the internal pressure in the tank or boiler, which exceeds a predetermined force.

  • the cover 1 can be rotated about the axis of rotation 6 relative to the flange 2 and the first arm 9 arranged on the flange, and thus relative to the dome opening or through opening.

  • This arrangement of the three auxiliary clamps 5 within this sector of the circle ensures that the lid 1 can be moved into the second rotary position because it moves the auxiliary clamps 5 with it.
  • the clamp 3 and the auxiliary clamps 4 are arranged in a sector of the circle, which lies on the other half of the circle. This prevents the dome cover arrangement from being rotated/moved from the second rotary position beyond the first rotary position.

  • the clip 3 engages behind part of the lid with a projection at its end, in that the clip 3 does not fit into one with this end edge recess 7 of the lid 1 intervenes.
  • the non-edge recess 7 ensures that the clip 3 cannot slide off the lid 1 in the direction of the edge of the lid.
  • the cover 1 is thus fixed by means of the clamp 3 in such a way that its rotational movement around the flange 2 or the bolt is restricted or prevented.
  • the clamp 3 would be arranged on the cover 1 and thus the clamp 3 would engage in a non-edge recess 7 of the flange 2.
  • a bracket should be in the other half of the circle than in the Figure 1 shown, so that it is prevented that the dome cover assembly can be rotated/moved from the second rotary position beyond the first rotary position, and so that the dome cover assembly can be moved from the first rotary position into the second rotary position.
  • the lid 1 tapers starting from the in the Figure 2 Thickness or height shown on the left initially moves to the right and thus forms a recess. It is not necessary that this is made in one piece.
  • the area of greater thickness or height could also be realized, for example, by screwing on a web or bracket, for example.

  • the cover is not restricted or limited by the auxiliary clip 4 and the auxiliary clip does not engage in the terminal recess arranged on the cover 1.
  • the lid 1 and the flange 2 can be moved from the second approximate position of the lid 1 and the flange 2 into the first distant position of the lid 1 and 2 due to an overpressure in a container below the lid 1, a through opening of which is enclosed by the flange 2 Flange 2 can be spent.

  • washers are arranged between them on the bolt.
  • a second exemplary embodiment of a dome cover arrangement according to the invention is shown, in which, among other things, instead of a usual clamp, a rotationally symmetrical clamp 3 or an anchor 3 or a locking bolt 3 is used as the surrounding element 3.
  • this locking bolt 3 is arranged on the cover.
  • the dome cover arrangement is shown in the second rotary position of the cover, in which the through opening 24 is released, allowing access to a tank, for example.

  • this exemplary embodiment has a pivot axis with which the cover can be pivoted relative to the flange in addition to the rotation about the axis 6 also about the pivot axis 25 and can therefore be folded open and closed, for example. This allows easy access to the underside of the lid.
  • two spit-shaped bulges 22 are arranged on the flange 2, wherein the openings of the spit, in particular the opening width, the opening angle and / or the opening direction, are each set up and arranged in such a way that when the lid 1 rotates of the second into the first rotary position, a surrounding element 3 is moved through the opening of the respective spit into the spit-shaped bulge 22.
  • the spit-shaped bulges 22 are arranged adjacent to an outer edge of the flange and each have an opening towards the edge of the flange.
  • an auxiliary clamp 4 is arranged on the flange 2, which is designed in the shape of a strip.
  • the auxiliary clamp 4 is further designed in such a way that, in the first rotary position in the distant position, the translational movement along the axis 6 away from the approximate position is restricted and/or prevented. This increases the stability and the possible pressure load of the dome cover arrangement. This is particularly advantageous when a pivot axis 25 is provided, but also generally for saving material on the axis 6 and the pivot arm.

  • the bolt 3 has a Projection, for example in the form of a head and a washer.
  • This projection is spaced apart from the connecting section to form a spacing section, the distance between the projection and connecting section remaining unchanged and/or unchangeable during rotation and during opening, closing and closing.
  • the spacing section of the bolt 3 surrounded by a sleeve has been moved through the opening of the spit-shaped bulge 22 by rotation from the second to the first rotary position.
  • FIG 8b is a top view of the non-edge recess of the dome cover arrangement according to the exemplary embodiment Figure 7 shown. Shown is the underside, i.e. the side of the flange facing away from the cover, which has the non-edge recess.
  • the non-edge recess is designed in such a way that its contour and/or outline and/or edges 23 encloses the recess of a bulge 22, here the spit-shaped bulge 22, at least partially, namely to more than 180° or approximately 250°.
  • Some of the recess may be marginal in relation to the recess, but not in relation to the flange, which is the point here.
  • the recess is spaced in all directions from the outer edge or edge of the flange and thus not marginal. There is therefore no recess on the outermost edges of the flange.
  • the recess which is therefore not at the edge, has an edge or a section of the edge of the recess which is not at the edge and/or which is directed in the direction of the opening and/or is located towards the bulge and/or towards the opening of the bulge.
