  • a quick-acting valve has a working cylinder which is vented by a hydraulic pressure against a biasing element, such as a spring, thus actively opening the quick-acting valve as long as the hydraulic pressure overcomes the bias of the biasing element.
  • a biasing element such as a spring
  • the DE 10 2004 042 891 B3 proposes for this purpose a control device according to the preamble of claim 1 with a cartridge valve for reducing the quick-release valve opening hydraulic pressure and a cartridge valve actuated this relief valve control valve assembly having three solenoid valves, which in a so-called 2-of-3 selection ("2v3 "-Selection), ie, are hydraulically connected to the relief valve, that this closes the quick-closing valve until at least two of the three valves of the relief valve control valve assembly are switched to a quick-closing position.
  • 2-of-3 selection so-called 2-of-3 selection
  • the DE 2 254 250 A proposes a 2v3 selection for the monitoring channels of a controller for a steam turbine trip valve to increase the reliability of the monitoring.
  • Object of the present invention is therefore to improve the availability, safety and reliability of a quick-closing valve for a steam turbine.
  • a control device for a quick-acting valve of a steam turbine according to the preamble of claim 1 is further developed by its characterizing features.
  • Claim 14 provides a quick-acting valve with such a control device, claim 15, a process executable by such a control device under protection.
  • a control device for a quick-acting valve of a steam turbine has a relief valve for reducing a hydraulic pressure which opens the quick-acting valve.
  • the quick-acting valve can, as explained above, in particular have a hydraulically actuable working cylinder, which can be moved by an appropriate hydraulic pressure against a biasing element, such as a tension or compression spring in an open position is and with sufficient reduction of the hydraulic pressure, the quick-closing valve closes.
  • This reduction of the hydraulic pressure and thus the closing of the quick-closing valve can be done via the relief valve, which may include, for example, one or more Cartdrige and / or ball valves.
  • a relief valve control valve assembly which has three or more valves which are hydraulically connected to the relief valve, that the relief valve closes the quick-closing valve only if at least two valves of the relief valve control valve assembly are switched to a quick-closing position , ie realize a 2v3 selection.

  • a test, in particular a so-called partial stroke test of the quick-closing valve can thus be carried out even when the relief valve is closed by first reducing the hydraulic pressure such that the quick-acting valve is completely removed, for example, starting from the quick-acting valve which is opened, for example, completely or in an operating standard position or at least partially closes, for example, by the working cylinder performs a full or a partial stroke. Subsequently, the hydraulic pressure is increased again and the quick-closing valve is returned to its original position.
  • the function of the quick-acting valve can be checked independently of the relief valve control valve arrangement and thus, for example, a binding or sticking, for example by scaling, can be detected.
  • the check-control valve assembly also provides a redundant, independent of the relief valve option to reduce the hydraulic pressure and so close the quick-closing valve, although possibly slower than through the relief valve.
  • Both the relief valve and the check control valve assembly are controlled so that hydraulic pressure is reduced over both and so the quick-closing valve is closed even faster.
  • the check control valve assembly on one or more first control valves and / or one or more second control valves.
  • a pressure source such as a hydraulic accumulator, a pump or the like
  • the connection of the relief valve with a pressure sink for example one or more tanks, can be done via the first and / or second control valves
  • First and second control valves may be connected in parallel or in series, wherein in the connection to the pressure source and / or to the quick-acting valve, a preferably adjustable throttle may be connected upstream to reduce the pressure applied to the test control valve assembly hydraulic pressure to a suitable value.
  • the relief valve control valve assembly and the check control valve assembly preferably form a structural unit.
  • these two subunits can form a compact block and be attached to each other and / or a carrier. This facilitates the installation of the complete control device and reduces the required space.

  • Valves of the relief valve control valve arrangement preferably connect the relief valve to a pressure sink or separate it from a pressure source when they are not supplied with energy, ie open the relief valve when de-energized.
  • a first and / or second control valves of the check control valve assembly connect the quick-acting valve to the pressure sink while disconnecting it from the pressure source when energized, ie close the quick-acting valve when energized.
  • the relief valve control valve assembly and / or the check control valve assembly preferably includes end position monitoring to determine if the valves are operating properly, i.e. take the controlled end position (open or closed position).
  • the controller includes a relief valve controller for sensing the speed of the steam turbine and switching the relief valve control valve assembly to the quick-closing position.
  • This relief valve control advantageously comprises at least three rotational speed detection units which are connected in such a way that the relief valve control valve arrangement is only switched to a quick-closing position if at least two rotational speed detection units detect a rotational speed of the steam turbine which exceeds a predetermined threshold value, i.e. realize a 2v3 selection.
  • the speed detection units may have a synchronization monitoring for mutual comparison of the detected speeds, a zero speed monitoring and / or an underspeed monitoring.
  • the speed detection units preferably communicate with each other via a bus capable of realizing the logic constituting the 2v3 selection.
  • external quick-closing commands so-called external trips, can be entered into the relief valve control, for example, from a performance monitoring of the turbine, a clutch monitoring or the like and as well as exceeding the predetermined threshold by at least two detected speeds for switching the relief valve control valve assembly in the Lead to quick-closing position.
  • the speed detection units may each have one or more speed detection devices, such as active speed sensors, and be physically independently connected to these and / or valves of the relief valve control valve assembly to increase reliability and safety.

  • the test-wise activation of the relief valve control valve arrangement and the test control valve arrangement can be controlled by a common test generator, but equally individual partial test generators may be provided which may preferably be implemented in the relief valve control or implemented separately from it.
  • the actuation of the valves of the relief valve control valve arrangement is preferably carried out such that the valves of the relief valve control valve assembly are alternately, in particular cyclically, individually switched to test mode in the SchneliBank position. Since with only one switched in the quick-closing position valve of the relief valve control valve assembly due to the 2v3 selection, the relief valve does not close the quick-closing valve, this test, for example, periodically, even during operation of the turbine.
  • the control of the test control valve arrangement is preferably carried out in such a way that the test control valve arrangement reduces the hydraulic pressure opening the quick-closing valve when the relief valve is closed and subsequently increases again so as to carry out a full or partial stroke test.
  • a partial stroke test can also be carried out during operation of the turbine, preferably before and / or after.
  • one or more sensors are preferably provided, which detect an adjustment of the quick-acting valve, for example a stroke of a working cylinder.
  • at least two sensors are provided at the same lifting height in order to distinguish between sensor failure, characterized by only one sensor signal, and faulty stroke, characterized by signals of all sensors
  • the test generator can be parameterizable in order to be able to set test conditions, for example the time duration between two tests, the partial lift height or the like.
