Definitions

  • the invention relates to a valve attachment with several Legs connected to a beam at one axial end are, a receiving space open at one end surrounded in the circumferential direction and a thread their radial outside, and with a nut, which can be screwed onto the thread.
  • Such a valve attachment is, for example, from DE 92 04 444 U1 known.
  • the invention is based on a radiator valve be described with a thermostatic head is provided.
  • the thermostatic head is on the valve attachment attached.
  • the valve attachment is mounted on the valve housing the radiator valve protruding from the radiator, postponed.
  • the legs have to be somewhat radial can spring outwards, especially if the valve housing and the inside of the legs together have adapted structures, for example projections and grooves. So that the legs make this radial outward movement the nut must be unscrewed his. To do this, the mother is usually up moves the area of the carrier facing away from the face is. Otherwise it would be unscrewed with the on Valve attachment no longer possible.
  • the invention is therefore based on the object To simplify assembly of a valve cap.
  • This task is the beginning of a valve attachment mentioned type in that on the front side opposite side of the thread a nut holder is arranged on the nut in the axial direction is definable.
  • the nut is outside the thread so held that they are in the axial direction can no longer move, at least not as long as one such movement is undesirable.
  • the determination is made of course solvable so that the mother then when the valve cap is pushed onto the valve housing has been screwed onto the thread can to tighten the valve cap on the valve housing to enable.
  • Fixing the mother with Help of the nut holding device prevents on the one hand that the mother in under the influence of gravity Direction on the thread can slip where it is radial Prevents outward movement of the legs. she lays on the other hand the mother at a defined point firmly, so that the subsequent unscrewing process for the Fitter becomes easier. Beyond that is the danger less damage during assembly. If the Mother is reliably held so that the legs are radial spring outwards when the valve cap is on the Valve housing is pushed on, then there is no risk of that with an often observed use of force Parts are damaged.
  • the nut holder is axially so related the thread is arranged so that the set The nut is axially completely outside the thread. This ensures that the intervention no hindrance to movement between nut and thread of legs.
  • the thread be made axially long enough so that the nut in screwed on the holding function reliably can meet. If the nut is screwed on, should namely reliable radial outward movement of the legs can be prevented.
  • the nut and the legs preferably have a radial one Play relative to each other when the mother is in the nut holding device is fixed.
  • the mother is not only axially backwards, i.e. of the Face away, postponed. It would only do that do not allow the area of the legs covered by the mother, to move radially outward. You leave rather a game between the legs and the mother also in the area covered by the mother.
  • the free length of the legs i.e. the area of Legs that can participate in the movement are enlarged and reduces the burden.
  • connection of the legs to the carrier arranged in the area of the nut holding device.
  • the slits between the legs are arranged and start from the front, ends in the area of the nut holder. So that will the suspension point of the legs, i.e. the point from which from a movement can begin in the area of Nut holding device relocated. This allows a relative large feather length.
  • the nut holding device is advantageous by at least formed a projection into the internal thread the mother intervenes. This is a very simple design a holding device. If the internal thread the mother and the tab are engaged axial movement of the nut is initially prevented.
  • the projection is preferably an external thread educated. Attaching the nut to the ledge respectively loosening the nut from the tab then done by simply turning the nut.
  • the external thread to predetermined Areas are limited in the circumferential direction. In order to there is little friction between the nut and the thread because the friction on relatively small Area areas is limited. This makes it easier especially loosening the nut from the nut holder. At the same time with an external thread also given a lead to the mother when she leaves the Mother holding device is released. Because it will automatically advanced towards the thread, so that the fitter practically only a rotary movement who has to do after loosening the mother from the nut holding device in the tightening movement continues. However, the release movement here is with one less effort than the movement, which is necessary for screwing down.
  • the regions are preferably the edges of the Legs adjacent in the circumferential direction. This contributes to an increase in the stability of the legs at. In addition, the mother then becomes reliable on every leg supported.
  • the external thread has one opposite
  • the internal thread of the nut has a reduced diameter.
  • the nut can be threaded M33 and the external thread as thread M32 or Train M31. On the one hand, this ensures that a game between the mother and the legs in the area the mother holding device exists.
  • the rotation of the nut on the thread without major Force can be applied. You can be the mother practically turn "with one finger” until it clicks on the Thread meets. Then in many cases at least Tighten a tool.
  • a valve cap 1, which on a valve housing 2 a Radiator valve to be placed has several four, legs 3 in the present exemplary embodiment on, which are separated by slots 4.
  • the legs 3 enclose a receiving space in the circumferential direction 5, into which the valve housing 2 fits, when the valve cap 1 is mounted on the valve housing 2 is.
  • the receiving space 5 is on its end face 6 open.
  • the legs 3 point on their radial inside projections 9 on the after mounting the valve cap 1 on the valve housing 2 behind a corresponding counter projection 10 in one Nut 11 come to rest. To make this possible the legs 3 must be able to radially when mounting to be moved out so far that the projection 9 can be moved over the projection 10 and then snaps into the groove 11. Conversely, after the Assembly ensure that such movement is no longer possible.
  • the legs 3 are provided with a thread 12.
  • the end face 6 is the thread by a Protrusion 13 completed, which prevents a Nut 14 in the direction of the end face 6 from the thread 12 is unscrewed.
  • the nut 14 has an internal thread 15 on the same diameter as that Has thread 12. For example, both threads are as M33 executed.
  • Thread 12 connects to thread 12 another External thread 16, but this is reduced Diameter.
  • This external thread 16 is for example with dimension M32. Accordingly exists even if the mother 14 on this external thread 16 is screwed, a small radial Game between the mother 14 and the legs 3.
  • the slots 4 also end in the area of this external thread 16th
  • the external thread 16 serves as a nut holding device.
  • the nut 14 is before assembly of the valve cap 1 on the valve housing 2 from the thread 12 and on External thread 16 screwed on. From there it can be without No more external influence on the thread 12. So you can spread the legs 12th not prevent, regardless of the position of the Valve attachment 1 is held. Because of the game between the mother 14 and the legs 3 is one Spreading, i.e. a radial outward movement of the Legs 3, easily possible. This movement will not hindered by the mother 14. It says not just the area of legs 3 between mother 14 and face 6 are available for movement, but the entire length of the legs 3.
  • the external thread 16 basically forms a projection, which engages with the internal thread 15 of the nut 14 stands and thereby an axial movement of the nut 14th prevented in the direction of the end face 6. Thereby, that this projection is formed as a thread is, the mother 14 can be done with relatively simple Transport movements in the direction of the thread 12. The fitter only has to turn the nut 14. This twist is due to the loose fit perform with relatively little force. The external thread 16 passes into the internal thread 12 so that the mother 14 is correctly guided during the movement.
  • FIG. 2a shows a section through the Valve attachment 1 in the area of his legs 3.
  • Fig. 2b and 2c represent sections along the line B-B, ie cuts through the external thread 16.
  • Fig. 2d represents one Section A-A, i.e. a cut in the area of the thread 12.
  • the external thread 16 is in the embodiment according to FIG. 2b limited to relatively narrow areas in the circumferential direction. In between there are gaps 17 that are free. Here the nut 14 simply slides on the bare outer surface of legs 3. The width of the thread sections can be chosen relatively narrow.
  • Fig. 2c shows that the external thread 16 also over the full circumference of the legs 3 can be performed. In both In some cases, the external thread 16 is designed as an M32 thread.
  • the thread 12 is shown in Fig. 2d is designed as an M33 thread, just like that Internal thread 15 of the nut 14.
  • the illustrated embodiment can be used in many ways Terms are deviated.
  • the external thread 16 can also use other means to hold the mother 14 are used, for example a snap-in connection, where some axial pull is required to to loosen the mother again.
  • a conical one would also be conceivable Widening of the carrier 7 at the transition to the legs 3, on which the nut 14 can be pushed and holds there under frictional force.
  • the Nut 14 also on its radial outside with suitable Funds are held.
