The present invention relates to a kind of pressure container apparatus, comprise one first pressure vessel and one second pressure vessel, they have a flange respectively in the end that faces one another, and they are contained in the variable-length section connection that is stabilized the part cross-over connection on the flange by one.
For example by the pressure container apparatus of the known this type of patent document DE19815151C1.The pressure container apparatus there has one first pressure vessel and one second pressure vessel, and they are equipped with flange.A variable-length section is installed between flange, and it is connected to each other first and second pressure vessel.
In order to protect the variable-length section to exempt from high mechanical load, adopt a stabilizing member.Stabilizing member has a plurality of stretching screws of arranging along flange circle distribution ground.
Stretching screw stretches out from flange.By on the flange excircle, setting up stretching screw, increased the structure space that needs.In addition, also there are many projectioies and pinnacle.
Therefore the purpose of this invention is to provide a kind of pressure container apparatus, it is designed to not have as far as possible projection.
Described purpose takes following measures to reach by the present invention in the pressure container apparatus of the described type of preface: stabilizing member has at least one annular framework that centers on the variable-length section, and the latter is connected with one of flange fixed angle ground (winkelstarr).
By using the annular framework around the variable-length section, stabilizing member can allow the variable-length section to change length, and prevents that the variable-length section is subjected to active force radially.Therefore the variable-length section is protected by the thin shell type of annular framework.Can stipulate that in this respect the annular of frame can design by the mode of the hollow cylinder with circular cylindrical cross-section.According to the height of hollow cylinder, can protect variable-length section or long or short section to exempt from applied external force.Therefore can preferably support the change of length vertically by the variable-length section.Can preferably use the structure that is designed to the box-like elastically deformable of ripple film as the variable-length section.For example can stipulate, the wall thickness of variable-length section is littler than the wall thickness of interconnected pressure vessel.
Because this variable-length section wall thickness is less, thus compare with the pressure vessel that for example is designed to self-supporting structure, more responsive for active force.
Even using when for example being designed to telescopic variable-length section, it also is favourable adopting annular stabilizing member.In this case, the seal area between the member that the variable-length section can be stretched each other can prevent to be subjected to external action.This seal area is the big place of mechanical stress, because must carry out the relative motion of repetition there between telescopic seal.Here seal area is designed to, it is able to take at the inner pressure that exists of pressure container apparatus and this pressure of energy withstand long term exposure.
Irrelevant with the structural design of variable-length section, this variable-length section portion has within it defined a volume, and this volume can be communicated with the inner chamber of one of pressure vessel at least.Between variable-length section and described at least one pressure vessel, adopt fluid seal to be connected for this reason.
