Definitions

  • the invention relates to a valve magnet comprising a coil and an iron circuit that are in a potentially explosive atmosphere Areas of usable housing arranged are, with the coil and the iron circle in one embedded in a housing part embedded potting compound are the entry of an explosive atmosphere prevents live parts and at the same time fixing and electrical insulation serves (encapsulation).
  • Types of protection according to IEC or EN are: “Flameproof encapsulation (EExd)", “Increased security (EExe) “,” Pressurized enclosure (EExp) “,” Intrinsic safety (EExi) “,” Oil Encapsulation (EExo) “,” Sand Encapsulation (EExq) “and” encapsulation (EExm) ".
  • the object of the invention is an explosion-proof To further develop valve magnets of the generic type in such a way that he fulfills the type of protection "Flameproof enclosure" in the connection area of external lines is easy and inexpensive to manufacture.
  • valve magnet of the type described solved the coil and the iron circuit in one in one housing part embedded potting compound are embedded, the Access to a potentially explosive atmosphere Prevents sharing and at the same time the Fixation and electrical insulation (encapsulation) and that connection elements of the coil in a housing part are arranged, which in the event of an explosion Withstands pressure and transmission inside Explosion to the environment prevented (flameproof encapsulation).
  • the big advantage of dividing the housing into two parts, one of which has the "encapsulation” type of protection and the others the type of protection "flameproof Encapsulation” has the great advantage that the Coil and the iron circuit, especially the magnetic closure sleeve is not part of the pressure-proof room.
  • This Housing part can thus be made without complex fits get along because of the flameproof column are required for flameproof enclosures. By avoiding such a column that is a mandatory The size can also have a minimum length of the magnet can be reduced.
  • Valve magnets In addition to its simple manufacture, such Valve magnets also advantageous that encapsulated Coils and iron circles or magnetic sleeves are available as standard parts, from which a smaller inventory results. Still they are external lines in a flameproof encapsulated, in the second housing part arranged space can be connected.
  • a valve magnet shown in FIGS. 1 and 2 includes a housing 10 which in two housing parts 11, 12th is divided.
  • the ignition protection type "encapsulation, EExm” fulfills Housing part 12 are in a potting compound 20 a Coil 30 and an iron circle 31 embedded.
  • the sink has a through opening 32 for receiving a Anchor on, by the in a known manner Valve can be operated in a potentially explosive atmosphere is.
  • the potting compound 20 are also electrical Connection elements 41 embedded, which over the Housing part 12 sealing compound 20 on the face side survive.
  • the potting compound 20 is used to keep explosive Atmosphere as well as fixation and electrical insulation.
  • These connecting elements 41 for connecting electrical Lines for actuating the coil 30 are in the other Housing part 11 arranged, the type of protection "Flameproof encapsulation" fulfilled. External lines will be via an opening 14 in the interior of the pressure-resistant encapsulated housing part 11 introduced.
  • the housing part 11 is on the end face by a cover 17 closed, the one trained on him Projection 17a in an end opening 18 of the Housing engages that the projection 17a over a predetermined length with the complementary to the projection 17a trained opening 18 to form a Ignition-proof gap between the projection 17a and the opening 18 overlaps. Furthermore, a Seal 60 may be provided in the assembled state arranged between the cover 17 and the housing 10 is.
  • the housing part 11 is designed so that it at Explosion of an explosive mixture in his Inside a pressure specified by standard regulations endures and a transmission of the explosion to the environment of the housing 10 is prevented.
  • valve magnet described above is in that the encapsulation of the housing part 12 and thus an explosion-proof valve magnet, which is the combined type of protection EExmd (encapsulation and flameproof encapsulation) fulfilled, on simple Way and therefore inexpensive to manufacture.
