Definitions

  • the invention is based on a pneumatic valve device at least two housing modules attached to each other according to the Preamble of claim 1 specified genus.
  • each housing module on two opposite flange faces of a cuboid Housing each a protruding mounting foot and one matching recess to accommodate the mounting foot of the neighboring one Has housing module.
  • Such screw connections are expensive to build, expensive and take up a lot of space, especially when small building valves is not available.
  • valve device with one another attached housing modules known as the pilot valve and main control valve are formed.
  • housing modules known as the pilot valve and main control valve.
  • One in the Parting plane lying tubular bolt the functions of the pressure medium connection and centering.
  • This valve device only a single bolt is provided, which is additional for the sealing O-rings used and that for its axial adjustment has a collar on the outside.
  • This valve device works with a hydraulic medium and is designed for high pressures, which is why the housing modules held together by screw connections become, which are correspondingly complex and expensive.
  • DE 35 22 955 A1 describes a pneumatic valve device known, the cuboid housing module for receiving several valve axles made of plastic, the housing module on a long side carries a metal connection plate on the the pressure medium lines can be attached.
  • the connection plate itself can be screwed or glued to the housing module are attached, alternatively a detachable bracket is provided is, with sleeve-shaped bolts made of rubber-like material in the Area of a parting plane in which the two components are inserted.
  • Each bolt has one for sealing in the parting plane lying outside waistband.
  • each pin half has an external, in cross-section semi-annular ring bead, which in corresponding Ring grooves are knotted in the channels of both components will.
  • the main disadvantage is that the rubber-like bolts can not transmit greater mechanical forces and therefore the metallic connection plate in a suitable groove of the housing module is sunk. Furthermore, the channels for receiving the semicircular ring beads can be machined in an expensive manner. Furthermore, only a detachable connector can be found here achieve which is undesirable in many cases. Also complicate the compliant bolts make assembly quick and easy.
  • DE-B-1 031 595 is a pneumatic Control device known in order to avoid individual pressure medium lines with several valve housings in a battery arrangement between at least two
  • An intermediate member is arranged from the valve housing a sleeve with the circumference fixed in recesses Sealing rings exist.

  • the sleeve can also be used on one side of the flange Provided with external thread. A rigid attachment of two Housing parts directly next to each other is not here provided, especially by the individually arranged Intermediate piece should remain limited mobility.
  • the plug connection by means of Hollow bolt is particularly space-saving because there are additional screws omitted as holding members and the functions of centering, the Sealing and the bracket are concentrated in a confined space. Due to the omission of the screws, no dirt corners in the Area of the screw heads.
  • O-rings can be dispensed with because the ring beads take over the sealing with their cutting edge.
  • the assembled bolts can have their cutting edges in the housing modules clawed so strongly that a secure and firm connection is achieved between the two housing modules.
  • This connector is therefore particularly suitable for small valves, especially if a pilot valve is mounted on the end of a directional valve. Especially It is favorable if a pilot valve with a plastic housing and for a main control valve with an aluminum housing, the bolts Steel are made to be safe, tight and durable To ensure connection. Furthermore, it is useful if at particularly high demands on the tightness and the bracket a bolt is used between the two housing modules, in which the cutting edges are arranged twice.
