Definitions

  • the invention relates to a damper actuator for butterfly valves for shutting off flue gas or exhaust air ducts, in particular ducts with large duct cross sections, with a drive unit for a drive shaft and with a tension lever mechanism between the drive shaft and a pivotably mounted butterfly valve, the drive unit being fitted with an angle lever attached to the drive shaft and has at least one cylinder piston arrangement articulated at a fixed point for actuating the angle lever.
  • Flap drives for butterfly valves which work with air or hydraulic motors which are operated from an air tank or from a bladder accumulator in the event of a power failure. Such flap drives are relatively expensive and often no longer functional after long downtimes. Because in the known embodiments, a gear consisting of rack and pinion is regularly used between the drive unit and the drive shaft. Such a gearbox requires sufficient lubrication if there is to be no seizure between the rack and pinion even after often long downtimes. Experience has shown, however, that there are difficulties with lubrication in such cases, so that it is often necessary to run dry. Such a dry run results in "seizure" until the gearbox becomes inoperative.
  • a folding blind for closing a delivery line for hot gases consisting of a frame that can be installed in the delivery line and has a number of parallel axes rotatably mounted in it, with louvre flaps attached to it, the flap axes protruding from and at least one end of the frame these ends are attached to flap arms which are connected to one another and to an actuating device for the louvre flaps by a linkage running outside the delivery line.
  • the linkage has a number of auxiliary levers which are connected to the respective flap arms and are of equal length, which are each arranged with pivot pins running parallel to the flap axes in a support rail to be arranged outside the delivery line and each have an arm which has the same length as the assigned flap arm , with which it is connected by an actuating rod in such a length that the auxiliary lever arm runs parallel to the flap arm at a certain temperature condition of the frame.
  • the auxiliary levers are designed as toggle levers (cf. DE 26 03 242).
  • the invention has for its object to provide a damper actuator for butterfly valves of the type described above, which is characterized by an inexpensive design and permanent functionality even after long downtimes.
  • the two cylinder piston assemblies can also be operated from an air tank or a bladder accumulator in the event of a power failure.
  • the two lever arms of the angle lever form a 90 ° angle and that one lever arm is in the starting position in approximately 7 o'clock / 8 o'clock position and that a cylinder piston arrangement with a retracted piston rod at the lever end of the a lever arm is articulated and is located with its fixed point bearing on one side of the drive shaft, and that the other lever arm is in the starting position in the 10 o'clock / 11 o'clock position and the other cylinder piston arrangement is articulated with the extended piston rod on the lever end of the other lever arm and is in an inclined position with the piston rod crossing a lever arm and with its fixed point linkage on the other side of the drive shaft.
  • the invention further teaches that for the two cylinder piston assemblies, a valve control, each with a multi-way valve, for. B. 4/3-way valve, and a limit switch is provided for the one lever end and the other lever end of the angle lever, and that the positions of the limit switches the angle of rotation for the simultaneous loading of the two cylinder piston assemblies or actuation of the two lever ends and consequently the stepless Specify the superposition of the torques.
  • a flap drive for a shut-off valve 1 for shutting off a flue gas duct 2 with a relatively large duct cross section is shown.
  • This flap drive has a drive unit 3 for a drive shaft 4 and a tensioning lever mechanism 5, which is arranged between the drive shaft 4 and the pivotably mounted butterfly valve 1.
  • the drive unit 3 has an angle lever 6, which is fixed in a rotationally fixed manner on the drive shaft, and two cylinder piston arrangements 7, 8.
  • the two cylinder piston assemblies 7, 8 are articulated on the lever ends 6a, 6b of the angle lever 6 and on fixed points 9, 10.
  • the two lever arms 11, 12 of the angle lever 6 form a 90 ° angle.
  • One lever arm 11 is in the starting position at about 7 a.m. / 8 a.m. position, the one cylinder piston arrangement 7 with the piston rod 13 retracted being articulated on the lever end 6 a of the one lever arm 11 and with its fixed point linkage 9 on one side of the drive shaft 4 - Based on a vertical axis M - guided by the drive shaft 4.
  • the other lever arm 12 is in the starting position - inevitably in the 10 o'clock / 11 o'clock position due to the 90 ° angle.
  • the other Cylinder-piston arrangement 8 is articulated with extended piston rod 14 on the lever end 6b of the other lever arm 12 and is in an inclined position with the piston rod 14 crossing a lever arm 11 and with its fixed point linkage 10 on the other side of the drive shaft 4 - again in relation to that through the drive shaft 4 guided vertical axis M.
  • the two fixed point linkages 9, 10 of the cylinder piston assemblies 7, 8 lie on the same plane.
  • the stroke of the two cylinder piston assemblies 7, 8 corresponds to a 180 ° rotation angle actuation of the respective lever arm or lever end of the angle lever 6 and consequently a 180 ° rotation movement of the drive shaft 4.
  • a valve control with a solenoid valve or 4/3-way valve 15, 16 and a limit switch 17, 18 is provided for one lever end 6a and the other lever end 6b of the angle lever 6.
  • the positions of the two limit switches 17, 18 specify the angle of rotation ⁇ for the simultaneous action on the two cylinder piston arrangements 7, 8 or actuation of the two lever ends and consequently for the continuous superimposition of the torques.
