Abstract
A pressure accumulator system, and a method of operating a pressure accumulator system. The method includes operatively connecting a tank neck to at least two pressure accumulator vessels having different admissible operating pressures, in which at least one of the pressure accumulator vessels has an admissible operating pressure lower than a maximum applicable pressure at the tank neck, simultaneously filling via the tank neck the at least two pressure accumulator vessels with a fluid medium, and preventing an inadmissible pressure rise in the pressure accumulator vessels with the lower admissible operating pressure during the simultaneous filling.
Claims9
A pressure accumulator system, comprising:
- a tank neck;
- pressure accumulator vessels, at least one of the pressure accumulator vessels having an admissible operating pressure that is lower than an admissible operating pressure of another pressure accumulator vessel;
- a valve unit to prevent an inadmissible increase in pressure at the pressure accumulator vessels, the value unit includes a shut-off valve, a check valve, and an overpressure valve each arranged in a common valve housing, wherein the valve unit has a shut-off pressure defined by the lower admissible operating pressure;
- and
- an electronic pressure measurement device and a control unit each operatively connected to the valve unit.
A pressure accumulator system, comprising:
- a tank neck;
- at least two pressure accumulator vessels, at least one of the pressure accumulator vessels having an admissible operating pressure that is lower than a maximum applicable pressure at the tank neck;
- at least one upstream device to protect the at least one of the pressure accumulator vessels against an inadmissible pressure rise, the at least one upstream device having a shut-off pressure defined by the lower admissible operating pressure, the at least one upstream device comprising a mechanical shut-off valve which, owing to a set spring force, is to sealingly close off a passage opening when a pressure of the at least one pressure accumulator vessel exceeds a predetermined value, and which does not open due to either a further increase in pressure, or a further decrease in pressure down to negative pressure, in a feed opening of the mechanical shut-off valve, that is to be connected upstream;
- pressure lines;
- and
- at least one withdrawal point.
