Definitions

  • the present invention relates to a solenoid unit for a solenoid valve, comprising a solenoid and a ferromagnetic circuit surrounding the solenoid, comprising a stationary magnet housing and a movable magnet armature. Furthermore, the invention relates to a method for producing such a solenoid unit and to a method for producing a magnet housing for such a solenoid unit.
  • Electromagnetically driven valves have a solenoid, a magnet armature for opening and closing the valve and a magnet housing.
  • the magnet housing consists of a U-shaped bent solid sheet metal part. These designs are preferably suitable for a DC drive. In an AC drive, these designs generate large eddy current losses. Taking into account the permissible heating, this means that less effective power and thus less magnetic force is available.
  • the generic DE 198 60 631 A1 known to produce the magnet housing in one piece from a metal strip, which is first punched out and then rolled or bent. The possibilities of shaping are limited here.
  • AC operated solenoid valves are equipped with magnet housings made of sintered ferrite material to avoid eddy currents. Although these are also suitable for operation with DC voltage, however, two valve designs are made for cost reasons. In contrast to an AC-operated valve, the magnet housing of a DC-operated valve does not use expensive special material such as sintered ferrite, but inexpensive sheet steel.
  • a solenoid unit which, in addition to a magnetic coil, has a ferromagnetic circuit surrounding it, which comprises a stationary magnet housing and a movable magnet armature.
  • a cover, shell and bottom of the magnet housing shown are composed of multilayer transformer sheets.
  • GB 2 040 585 A discloses the preamble of claims 1 and 12.
  • the object of the present invention is to specify an electromagnet unit and a method for producing a magnet housing of a solenoid unit whose cover part is designed such that the electromagnet unit can be used flexibly for different types of solenoid valves.
  • the invention provides a solenoid unit for a solenoid valve having the features of claim 1, wherein the magnet housing is composed of a cover, a shell and a bottom in the form of multilayer transformer sheet metal parts.
  • Transformer sheets are particularly suitable because they have a small thickness of a few tenths of a millimeter in addition to the appropriate magnetic properties. Furthermore, transformer sheets are an industrial mass product and correspondingly inexpensive to use. They are also available with an electrically insulating coating, which is an advantage for even better eddy current reduction.
  • the transformer sheet metal parts are stamped and bent as needed. Since the sheet metal parts used have a small thickness, these processing steps are simple and inexpensive to carry out.
  • the transformer sheet metal parts have multiple layers, it being possible that these layers are interconnected. This increases the stability of the transformer sheet metal parts and reduces the gap width between the individual Layers. Suitable connection methods are, for example, packaging, gluing or riveting.
  • the bottom and / or the lid may have a central opening.
  • a simple assembly of the solenoid unit is possible, for example, by simply inserting the armature, the armature counter-pole and / or a core guide tube axially.
  • a radial slot extending from the central opening to the outer circumference is preferably provided in the lid and / or in the bottom. This slot reduces occurrence of eddy currents in the circumferential direction of the lid or the floor.
  • the bottom and / or the lid may be caulked in the assembled state with the jacket. This is a particularly inexpensive and reliable method of attachment.
  • the solenoid Before the connection of the sheet metal parts, the solenoid can be easily inserted into the shell, so that very easily a pre-assembled assembly of the bottom, the cover, the shell and the solenoid is created by caulking.
  • the shell of the magnet housing has at least one opening, and the magnet coil is potted, pressed or overmolded.
  • a liquid plastic material is introduced into the magnet housing, so that the solenoid receives a plastic embedding. After curing of the plastic mass possible gaps or cavities are closed and the sheet metal parts of the magnet housing and the solenoid are fixed so that the occurrence of rattling noises in valve operation is no longer possible.
  • the jacket may have a smaller thickness than the bottom, wherein the bottom may also have a greater thickness than the lid.
  • increased magnetoresistance which occur mainly on the ground by the non-magnetic core guide tube and the air gap to the movable armature, compensated by larger Blechteildicken.
  • the sheet metal thickness Due to the multi-layer structure of the sheet metal parts, the sheet metal thickness can be varied very easily over the number of layers.
  • the layered sheet metal parts of the cover, shell and bottom may vary in thickness and property of the individual sheets, e.g. isolated or not isolated, differ.
  • the cover comprises an inner cover part and an outer cover part, wherein the outer contour of the inner cover part is complementary to the inner contour of the outer cover part, so that the cover parts can be assembled in a form-fitting manner.
  • a cover part is not a single Designated transformer plate of the lid, but a built-up of several transformer laminations laminated core.
  • This construction of two cover parts has the advantage that the produced with relatively high effort, inner cover part can be used identically even with different cover sizes and the necessary adjustment is made by the producible with less effort, outer cover part.
  • Due to the positive connection of the lid composed of inner and outer lid part acts substantially as a one-piece (but constructed of several metal layers) lid, so that the magnetic flux is not affected in the lid plane.
  • the outer cover part is U-shaped.
  • the protective conductor terminal of the inner lid part which is responsible for the increased production cost of the inner lid part, in all the execution sizes of the lid is easily accessible.
  • the lid may have a cover part which covers the assembled lid parts.
  • the sheet metal thickness of the laminated core is increased for larger covers on the one hand, on the other hand, the base of the lid is not separated over its entire thickness by a joint between the inner and the outer cover part. Both contribute to a reduction of the magnetoresistance.
  • a magnet housing for a solenoid unit which is suitable for both a DC drive and an AC drive, easily and inexpensively manufactured.
  • the cover prior to assembly of the magnet housing, is composed of an inner cover part and an outer cover part, wherein the outer contour of the inner cover part is complementary to the inner contour of the outer cover part.
  • the cover parts are then connected positively and / or non-positively.
  • the positive connection, but also a possible frictional connection perpendicular to the lid plane provide for an unimpeded magnetic flux in the lid plane and are easy to manufacture.
  • the cover parts with the complementary contours are preferably punched, the frictional connection can e.g. be achieved via a press fit between the lid parts.
  • the legs of the U-shaped cover part can be pressed apart and deformed during positive connection with the inner cover part slightly so that they clamp after the connection, the inner cover part and prevent relative movement between the cover parts perpendicular to the cover plane.
  • a cover part can additionally be attached to the inner and / or outer cover part.
  • a cover member which is constructed as well as the inner and outer cover part of transformer plates, the cover thickness can be adapted very easily with increasing cover surface, i. be enlarged.
  • the cover is caulked for example with the inner and / or outer cover part.
  • the assembly of the magnet housing begins even before the insertion of the magnet coil into the shell, by already producing a positive connection between the bottom and the shell or the cover and the shell. Accordingly, this substep is omitted in step E.
  • the magnet housing and the magnet coil are produced in the same way as a preassembled unit, wherein the magnet coil is protected inside the preassembled unit.
  • a liquid plastic mass is introduced into the assembled magnet housing through an opening provided in the magnet housing to embed the magnet coil.

  • the magnet coil 10 When the magnet coil 10 is energized, the magnet coil is formed inside the magnet coil axially aligned magnetic field.
  • the armature 14, the armature counter-pole 16 and the magnet housing (in detail the cover 18, the bottom 20 and the shell 22) form a ferromagnetic circle, which is decisive for the force on the armature 14.
  • the axial extent of the air gap 28 is equivalent to a drive stroke of the solenoid valve.

  • the individual components preferably comprise 2 to 9 layers.
  • the layers of the components can be connected, for example by packaging, gluing or riveting.
  • the sheet metal parts of the magnet housing can be varied very easily in their thickness by a sizing of the number of layers.
