Definitions

  • the present invention relates to the screw compressor sector and in particular to a modular system for connecting accessories, in particular suction valves, to a compressor group.
  • suction valves meet the technical requirements of many compressor groups, it is known that special suction valves have to be manufactured for each individual compressor type at the moment, since they require different connections, which is why different processing codes are required for the same accessory.
  • the aim of the present invention is therefore to eliminate these disadvantages by producing an intake valve group for screw compressors, which offers greater flexibility in the use of the intake valve even in different compressor groups.
  • a first advantage essentially consists in the possibility of connecting the same suction valve body to different compressors by simply using an appropriate, separable flange.
  • a second advantage is that two or more flanges allow a large number of possible connections thanks to differently aligned and positioned mounting slots, even with mounting schemes other than those currently used in the existing compressor groups.
  • Fig.l is a perspective view of an assembly according to the invention
  • FIG. 2 shows an exploded view of the assembly from FIG.
  • the invention comprises an intake valve body 1, which is provided with a first coupling surface 4 and at least one separate flange 2, which in turn is provided with a second coupling surface 5, which is congruent with the surface 4 of the body 1.
  • valve body 1 The inner parts of the valve body 1 are known per se and are therefore - apart from the parts relevant to the invention - not described in detail.
  • the flange 2 is also provided with through bores 8, which are made on the inner projections 11 and through which the fastening screws (not shown) can be screwed, which serve to serve in the holes 9, which are on the corresponding inner projections 12 of the coupling surface 4 of the body 1 are attached to intervene.
  • a seal 17 (for example an O-ring) is preferably also provided, which is inserted between the coupling surfaces 4 and 5 of the body 1 and the flange 2.
  • the flange 2 is also provided with a multiplicity of slots 3 in order to be fastened to a screw compressor group by means of fastening means (not shown) (for example stud bolts) of a known type.
  • fastening means for example stud bolts
  • the flange 2 has the shape of a parallelepiped with a square plan, while the slots 3 are arranged on the diagonals of the square, at the corners thereof.
  • At least two interchangeable flanges are provided for attachment to the body 1, both of which are each provided with attachment slots.
  • the slits of the flanges are preferably suitable for fastening with 8 - 12 mm screws and have a length of 20-30 mm.
  • the template with the possible points for attachment to the compressor group (shown schematically with number 15 in FIG. 2) that results from the impression of the slots of the various flanges forming part of the assembly (their shapes, sizes, orientations and positions partially or completely different) results, advantageously possible, to fasten the valve body 1 to a larger, even hitherto non-existent, number of compressors, the fastening holes of which fall into the areas outlined by the slots 3 of the various flanges.
