Definitions

  • the invention relates to an integration block for pneumatic circuits of, in particular, pressure-fluid-operated devices in an embodiment according to the preamble of claim 1.
  • Integration blocks of the above type are increasingly interested in the implementation of integrated pneumatic circuit arrangements, it being possible for accommodating passages or bores and channels for connecting or interconnecting logic elements mounted on the block in the integration block.
  • external hose connections, fittings, etc. between individual switching or control elements can advantageously be dispensed with.
  • Such integration blocks are also characterized by an extraordinarily easy to assemble and repair, are also inexpensive to manufacture, in particular in larger quantities, and thus make devices and machines which are equipped with the block less expensive than control and switching elements connected via hose connections and the like provided devices considerably.
  • integration blocks of conventional design generally have plate bodies made of plastic which are glued to one another and for the joint formation of Control channels each have paired formations with an approximately semicircular cross-sectional structure.
  • these integration blocks can only be used to a limited extent and are also suitable for operation at only relatively low operating pressures. Dirt particles adhering to duct walls, for example aggressive media from compressors required for generating compressed air, attack the plastic material, so that after certain time intervals due to the fact that the plate bodies can be removed, the blocks must be completely renewed.
  • valve block with a housing part in which a recess is provided for the essentially form-fitting insertion of a sealing plate. Due to the lateral delimitation of the seal by the edge surrounding the recess, it is possible to counteract a flow of the seal at higher operating pressures, but system leaks cannot be avoided with this valve block at operating pressures of 10 bar and more.
  • an integration block for pneumatic circuits in which, with the interposition of a sealing element, plate bodies with channels aligned parallel to the longitudinal plane of the plate body, perpendicular to these passages for connecting control and switching elements which can be fastened to a plate body, and Inlet and outlet openings must be fixed to one another in a pressure-tight manner.
  • the sealing element is arranged in a plate recess on the side of the plate body with a form recess edge which essentially surrounds the sealing element in a form-fitting manner, the sealing element for fixing the position having an asymmetrical edge contour and the form recess edge for the form-fitting delimitation of the sealing element being complementary to the seal-side asymmetry.
  • an integration block according to the features of claim 1. Due to the projections starting from the base of the recess, defined squeeze sealing webs can be created in the areas of the pressure medium-carrying channels or passages in the assembled state, with which the functional unit can be securely sealed even at operating pressures of more than 10 bar, without the need for any additional sealing parts.
  • the sealing means in the areas of the projections are to be introduced via the fastening devices to be provided, expediently screws, in such a way that they lie over the projections. Due to the lateral delimitation of the seal by the shape recess edge, the seal is further prevented from flowing away.
  • the sealing element Due to the corresponding asymmetrical design of both the shape recess edge and the seal itself, it is also to be ensured with structurally simple means that the sealing element is placed in a positionally correct manner in terms of handling technology by inserting it into the shape recess and even after repeated disassembly or assembly of the plate body is. If, for example, the block is to be cleaned, serviced or repaired, an upper plate body can be removed.
  • the seal is so dimensionally stable due to the partially recessed arrangement in the mold recess even at high plate body contact pressure due to the delimitation by the mold recess edge that a secure seal is ensured even over long periods of time and repeated disassembly and assembly.
  • the integration block generally numbered 1 in the drawing, has a lower plate body 2 and an upper plate body 3 which can be fastened thereon.
  • the integration block of the illustrated exemplary embodiment should z. B. Used in pneumatic control circuits of pressure-operated devices, for example in building ventilation systems provided with a positive actuation device, in which ventilation flaps are actuated automatically in the event of fire, but is equally suitable for use in other machines and devices in which pneumatic and / or electropneumatic logic elements are required for control.
  • the control and switching elements to be attached to the upper side of the upper plate body, for example solenoid valves, control pistons and the like.
  • the channels 5, which are aligned via inlet and outlet openings 4, parallel to the longitudinal plane of the plate body, and perpendicular to the channels 5 through holes 6 to be interconnected.
  • only the lower plate body 2 is provided with the inlet and outlet openings 4 and the channels 5.
  • the upper plate body 3 has the vertical through openings 6 opening into the supply openings of the control and switching elements.
  • the channels 5 run in the lower plate body 2, depending on the desired circuit diagram, in different orientations parallel to the longitudinal center plane of the lower plate body 2 and can, for example in the plan view according to FIG. 1, have partial areas running at right angles to one another, also have different radii of curvature and also have an oblique course What is not possible with known integration blocks made of plastic with glued plate bodies due to the adhesive surfaces to be made available.
  • the illustrated exemplary embodiment has a shaped recess, generally 7, which extends over a wide region of the lower plate body surface and is delimited by the relatively small width of the shaped recess edge 8 running along the outer edge of the lower plate body 2.
  • a single sealing element 9 (FIG. 2) corresponding to the contour of the shaped recess.
  • the channels 5 and also the through bores 6 running perpendicular to the channels 5 are delimited in the region of the mouths by projections 7.1 which start from the base of the shape recess and are web-like in the illustrated embodiment, which merge into one another and in some cases also delimit threaded holes 13 provided in the plate body 2.
  • Both the recess 7 and the projections 7.1 can be produced by milling with relatively little structural effort.
  • the projections 7.1 do not extend to the surface of the mold recess edge 8, but preferably have a height which is formed with a dimension of 30% to 70% of the dimension of the mold recess depth.
  • the seal 9 preferably has an excess compared to the distance between the upper edge of the projections 7.1 and the surface of the shape recess edge 8, so that when the block is assembled after tightening the fastening screws 12, the sealing body 9 is constricted in the region of the projections 7.1 and extends over the respective side edges of the Protrusions 7.1 sets, so that even high operating pressures withstanding pinch sealing surface areas are created.
  • the seal 9 is designed such that it projects beyond the shape recess edge 8 in the disassembled state by about 30% of its cross-sectional thickness, so that after tightening the fastening screws 12, the sealing element expediently consisting of an elastic rubberized cork material is compressed to such an extent that the plate bodies 2, 3 lie approximately in the edge of the plate body.
  • a number of fastening screws 12 are provided for fastening the upper plate body 3.
  • the screws 12 are provided not only in the edge areas of the plate bodies 2, 3, but in other plate areas, in particular also in between channels and passages open spaces.
  • the lower plate body 2 has different, substantially unevenly distributed threaded bores 13, which are each placed at a distance from one another in such a way that without the requirement of z. B. any type of curvature or the like. A secure seal of the plate body is guaranteed.
  • the upper plate body 3 is held on the lower plate body 2, so that it can be removed and assembled together with the attached control and switching elements without the need to disassemble the lower plate body 2 if necessary.
  • the lower plate body 2 in turn is to be fastened by means of screws which are not visible in the drawing and which extend through through bores 14 in the lower plate body 2 and likewise through through openings in the upper plate 3 which are not visible in the drawing.
  • the fastening screws of the lower plate body 2 are accessible from the outside, so that the block or the lower plate can be attached or removed without dismantling the upper plate body 3.
  • the total assembly effort required is limited to just a few simple steps, so that both the block and individual parts can be handled easily and safely by inexperienced people.
  • a factory prepared upper plate body 3 with attached switching and control elements can be replaced quickly and easily without the help of a specialist, so that the unit cannot fail due to longer-lasting repair or maintenance work.
  • the sealing element 9 is provided with passages.
  • the shape recess edge of the lower plate body 2 has two edge zone regions provided on opposite corner regions with an edge zone contour drawn inward essentially in the shape of a nose.
  • the sealing element 9 is designed to be complementary in these edge regions.
  • the two opposite edge zone deformations or contours are designed such that the sealing element 9 is to be arranged in the mold recess 7 in only one specific position. Incorrect insertion of the seal is thus ruled out, and a precise fit of the sealing element 9 is also ensured on the projections 7.1 after any disassembly.
