Definitions

  • integration blocks of conventional design generally have plate bodies made of plastic, which are glued to one another and, for the joint formation of the control channels, each have mutually cooperating formations with an approximately semicircular cross-sectional structure.
  • these integration blocks can only be used to a limited extent and are also only relatively small Operating pressures are functional. 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.
  • the integration block has a lower plate body 2 and an upper plate body 3 which can be fastened to it.
  • the integration block of the illustrated exemplary embodiments is to be used, for example, in pneumatic control circuits of pressure-operated devices, for example in building ventilation systems provided with a positive actuation device, in which in the In the event of a fire, ventilation flaps are actuated automatically, but is equally suitable for other machines and devices in which pneumatic and / or electropneumatic logic elements are required for control purposes.
  • the control and switching elements which can be fastened to the upper side of the upper plate body 3, for example solenoid valves, control pistons and the like.
  • the channels 5 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.
  • 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 have, for example, partial areas running at right angles to one another in the plan view according to FIG. 1, have different radii of curvature, and also have an oblique course, which is not possible with known integration blocks made of plastic with glued plate bodies due to the adhesive surfaces to be provided. With these blocks of conventional type, only channels of parallel alignment are to be provided in each panel, so that if differently aligned channels are required, several panel bodies are necessary.
  • the exemplary embodiment according to FIGS. 1 and 2 has a shape recess, generally 7, which extends over a wide area of the lower plate body surface and is limited by the relatively small width of the shape recess edge 8 running along the outer edge of the lower plate body. All the channels 5 extend in the plate body region located within the mold recess edge 8, which are thus to be sealed or covered upwards by a single sealing element 9 (FIG. 4) corresponding to the contour of the mold recess.
  • the seal 9 which in turn has through openings 10 or channel-shaped openings 11 for connecting the channels 5 to the passages 6 or the control and switching elements or internal connection of individual passages or channels, is essentially positively delimited by the shape recess edge So that even with high tightening torques of the screws 12 fixing the upper plate body to the lower plate body 2 and higher operating pressures, there is no fear of the seal flowing away and a functional sealing of the block is ensured even over long operating times.
  • the sealing element 9 has a cross-sectional thickness or height which is dimensioned such that it protrudes beyond the mold recess 7 in the disassembled state of the plate bodies 2, 3 and is therefore arranged in a partially recessed manner therein.
  • the seal 9 protrudes beyond the shape recess edge 8 by a maximum of 30% of the cross-sectional thickness, so that after tightening the fastening screws 12, the sealing element, which expediently consists of an elastic, rubberized cork material, is compressed to such an extent that the plate body 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 in free spaces located between channels and passages.
  • the lower plate body 2 has different, essentially unevenly distributed threaded bores 13, which are each placed at a distance from one another in such a way that a secure sealing of the plate body is ensured without the need for any kind of curvatures or the like.
  • 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 is in turn to be fastened by means of screws which are not visible in the drawing and which extend through through holes 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 is fastened without dismantling the upper plate body 3 or can be removed.
  • the total assembly effort required is limited to just a few 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 15.
  • the shape recess edge 8 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 a nose-like manner.
  • the sealing element 9 (FIG. 4) is designed to be correspondingly 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. Faulty insertion of the seal is thus ruled out and a tight fit of the sealing element 9 is ensured.
  • the plate bodies 2, 3 of the exemplary embodiments illustrated in the drawing consist of metal and are made of aluminum, for example.
  • the plate bodies are expediently milled from a block of material.
  • the channels in the required number and orientation as well as the shape recess are milled equally.
  • plate body surface areas comprising at least channels and / or housing passages are expediently lapped and provided with a coating, for example a surface layer produced by anodic oxidation.
  • the metal ones plate bodies offer sufficient strength properties to withstand high operating pressures and screw tightening torques. Even aggressive print media cannot attack the plates.
  • the channels can be aligned in any way.
  • the plate bodies 2, 3 can also be sealed by other suitable sealing elements, for example by a plurality of individual seals arranged in the region of channels 5 or passages 6 assigned to one another.
  • the sealing element consists of a seal 9 which is rectangular in cross section and can be inserted into an equally rectangular shaped recess 7 and which covers the channel upwards and in turn has openings 16 in the region of passages to be connected to one another .
  • the sealing element 9 is designed as an O-ring.
  • a groove-shaped recess 8 is provided which surrounds the channel 5 at a short distance, so that the channel 5 in the assembled state is not covered upwards by the sealing element, but by the O also defining the passages to be connected to one another. Ring is effectively sealed.
  • the sealing element is designed in a similar manner to the O-ring of the exemplary embodiment according to FIGS. 9, 10, 11, but has a rectangular cross-sectional sealing surface.
  • this sealing element 9 directly delimits the channel 5 and the passages 6 connected to one another by the channel 5.
  • the shaped recess 8 accordingly connects directly to the channel 5.
  • FIG. 1 An integration block with a total of four plate bodies 2, 3, 17, 18 is illustrated in FIG. Between the plate bodies there is in each case a large, one-piece sealing element in an analogous configuration to the sealing element 4 or 5 to be arranged in a mold recess 9.
  • the control and switching elements, not shown, should in turn be attached to the upper plate 3.
  • the fastening screws 19 and 20 of the middle plate bodies 17, 18 engage like the screws 12 of the upper plate 13 in the next lower plate and are accessible from above, so that the individual block plates or the proportional block in the respectively required or Desired sense can be dismantled.
  • the plate bodies 2, 17, 18 each have the inlets and outlets 4, have channels 5 and passages 6, so that there are a multitude of control circuit options.
  • FIG. 16 A detail of an inlet or outlet opening 4 of a plate body 2 is illustrated in greater detail in FIG. 16.
  • a total of 21 connector socket is screwed, for which purpose the opening 4 is provided with an internal thread 22.
  • the connection socket is to be sealed in the opening 4 by means of an O-ring 23.
  • the connection socket 21 in turn has an inner shoulder shoulder 24.
  • In the connection socket 21 is an adapter for z.
  • the connecting socket 21 has an inner molded shoulder 27 for receiving a further O-ring 28 which, in the assembled state, is located in front of the tip of the locking lug 26 and is supported on a shoulder which delimits the molded recess.
  • a further O-ring 28 which, in the assembled state, is located in front of the tip of the locking lug 26 and is supported on a shoulder which delimits the molded recess.
  • the pipe section 30 that can be inserted into the pipe connector 25 and is schematically outlined in FIG. 18 is sealed. Due to this design of the inlet or outlet opening and the connecting sockets or adapter pieces which can be inserted into these openings, it is not necessary to glue in connecting sockets, so that they are also removably attached. Likewise, the prerequisite has been created to connect copper pipes to the integration block. To dismantle the connector socket 21, this has an internal, generally with 31 numbered hexagon socket inner cross-section, of is accessible from the outside and allows easy disassembly or replacement.
