Definitions

  • the present invention relates to a directional valve according to the preamble of claim 1 and its use.
  • Hydraulic directional control valves are known, which are designed as seat valves or as valves with longitudinal or rotary slide valves.
  • the actuation can be mechanical, electromagnetic or hydraulic.
  • the switching frequency and robustness of the valves depends very much on the design.
  • a directional valve of conventional design cannot be used for use in a vibratory hammer, since the requirements for compactness, robustness (acceleration up to 300g) and switching frequency are far too high.
  • the present invention has for its object to provide a directional valve which is suitable for installation in hydraulic vibrating rams. According to the invention, this is solved by the characterizing features of independent patent claim 1.
  • Fig. 1 the functional diagram of a 4/2-way valve with hydraulic actuation is shown.
  • the valve comprises a valve housing 1 with an upper housing part 2 and a lower housing part 3.
  • An intermediate plate 4 with an eyeglass-shaped seat 5 for two switching disks 6 and 7 is arranged between the upper and the lower housing part.
  • the upper housing part 2, the lower housing part 3 and the intermediate plate 4 are provided with seals, not shown, and connected to one another by screws and centering pins, also not shown.
  • the S chaltusionn 6 and 7 are arranged in tight valve housing with clearance. Both discs each have two switching holes 8 and 9, respectively. 10 and 11, which chaltusionn-axially into the S are arranged. Only one or more holes per disk could also be provided be.
  • the axial bores 16 and 18 are connected to one another by a horizontal channel A provided in the lower housing part 3 and the axial bores 17 and 19 are connected to one another by a horizontal channel B also provided in the lower housing part 3.
  • the vertical bores 16, 17, 18 and 19 extend through the lower and upper housing part, the mirror bores in the upper housing part being blind, but having the same diameter and the same position as the bores opposite them in the lower housing part. These blind holes equalize the pressure.
  • the switching disks 6 and 7 each have six axial pressure compensation bores 20 in two parallel rows to the slots 12 and 13, so that in the closed state, ie when the switching bores of the switching disks do not match the vertical bores 16, 17, 18, 19 in the housing communicate, which are connected to each other in the lower and upper part of the housing via a pressure compensation hole.
  • FIG 5 shows the position of one switching bore in two different, closed positions. In positions between these positions, the switching bore 8, 10 communicates with the bore 16, 18 in the valve housing.
  • the switching disks ie. the slots 12 and 13 arranged in them are shown in four different positions.
  • positions a and c the inlet and. Return holes P and T are not connected to channels A and B.
  • the inlet bore P of the left switching disk is connected to the channel A and the return bore T is connected to the channel B.
  • the inlet bore P of the left switching disc is connected to the channel B and the return bore T of the right switching disc is connected to the channel A.
  • the holes Z 1 or Z 2 the working medium enters the area of the toothing of the two switching disks 6 and 7, and through the other hole the working medium flows back to a container located outside the valve.
  • the speed of the switching discs 6 and 7 depends on the flow rate of the drive medium and can be influenced from the outside. Both switching disks 6 and 7 rotate synchronously as a result of the toothing 14 and 15 attached to their circumference, the switching bores 8, 9, 10 and 11 in the switching disks 6 and 7 the bores 16, 17 located in the upper and lower housing parts 2 and 3, Roam 18 and 19.
  • the filled points in the drawing represent any two points on the circumference of the switching disc and illustrate the synchronous rotary movement of the switching discs under the influence of the drive medium.
  • the slots 12 and 13 in the switching disks 6 and 7 each connect both switching holes 8 and 9 provided in the disks. 1 0 and 11 permanently with the hole P for the working medium supply, respectively. with the hole T for the working medium return.
  • each switching disc 16 and 17 with a hollow bearing pin 21 and. 22 equipped, which transmits the radial forces to the bearing bushes 23 and 24 provided in the valve housing.
  • the radial forces can be largely reduced by relief grooves 25 and relief channels 26 in the intermediate plate 4.
  • only one switching bore is provided per switching disk, in which case the switching bore with the inlet resp. Return hole in the housing connecting slot in the switching disc can only be formed on one side.
  • the channels A and B provided in the lower housing part 3 are connected with lines which lead to a vibration cylinder, where alternately one side of the piston and then the other side of the piston are pressurized.
