Definitions

  • the invention relates to an above-ground water column, as described in the preamble of claim 1.
  • the object of the invention is to provide an above-ground water column in which adequate protection against unauthorized commissioning and rapid commissioning is achieved if necessary.
  • An embodiment according to claim 2 is advantageous, as a result of which the coupling device remains “engaged” in the operating state, and thus closing of the case is achieved without additional manual actuation.
  • the drive arrangement for the uncoupling is simplified in order to avoid adjusting elements for an opposite drive.
  • an embodiment according to claim 5 is also advantageous, as a result of which components which are easy to manufacture and are suitable for combined use are achieved. According to the advantageous developments, as described in claims 6 and 7, there are control surfaces for the drive arrangement for adjusting the coupling elements, which inevitably lead to a predetermined end position.
  • the design according to claim 8 enables the arrangement of the drive within the jacket cover part without disruptive drive elements projecting beyond its outer contour.
  • An embodiment according to claim 9 is also advantageous, as a result of which an automatic engagement and latching takes place when the case is raised in its upper end position.
  • the claim 14 describes a simple arrangement for the control cam of the shift shaft.
  • an embodiment according to claim 15 is also advantageous because this results in a central application of force to the coupling elements.
  • An embodiment according to claim 16 is also possible, whereby a simple key tool can be used for commissioning.
  • training according to claims 37 to 39 are also advantageous because this ensures that the water column is depressurized, i.e. is emptied, e.g. Avoid frost damage before the fall jacket can be brought into its closed position and an additional vent valve for emptying the pressure pipe after the water column has been shut down is saved.
  • Figure 1 is a water column according to the invention in view, partially sectioned.

Abstract

L'invention concerne une colonne d'eau en surface (19 comprenant un tuyau de pression (11) s'étendant verticalement depuis un point de jonction (4) d'une conduite d'alimentation (5), situé en surface et un système de soupapes (16) monté sur le tuyau de pression (11), qui est recouvert d'une partie d'enveloppe extérieure (31) et d'une enveloppe descendante (29) désaccoupable. La partie d'enveloppe extérieure (31) est reliée mobile à une tige d'ajustement (25) d'une soupape de pied (9) disposée dans la conduite d'alimentation (5), ladite tige d'ajustement étant disposée de manière centrée dans le tuyau de pression (11). L'enveloppe descendante (29) peut être reliée accouplée à la partie d'enveloppe extérieure par l'intermédiaire d'un dispositif d'accouplement (30). Dans une position fermée de l'enveloppe descendante (29), dans laquelle le système de soupapes (16) est gainé, un système de blocage amovible empêche la partie d'enveloppe extérieure (31), sous forme d'élément d'actionnement (27) et par conséquent la tige d'ajustement (25) de se déplacer.
