Definitions

  • the invention relates to a device for connecting a radiator valve, in particular a thermostatic valve, to a radiator, with a connecting nozzle which has at one end a support flange with a union nut for connection to a nozzle of the radiator valve and in the region of the other end a radiator connecting plug.
  • the connecting sleeve has a predetermined length, the supporting flange on the one hand and the radiator connecting plug on the other hand being integrally formed on or firmly connected to the connecting sleeve.
  • the end of the radiator connecting plug has a thread which is screwed into an associated threaded hole in the first member of the radiator (radiator) until a sealing flange provided at the threaded end rests on an associated sealing surface of the first member of the radiator.
  • the radiator connection plug On the grommet side, the radiator connection plug has a profile section for attaching a tool directly next to the sealing flange.
  • the radiator connection plug with the connection grommet is screwed into the first element of the radiator. Then the union nut is screwed onto the external thread of the radiator valve. Now the connecting line leading to the radiator valve is cut to length and provided with an external thread such that an assigned connecting piece of the radiator valve can be screwed onto the thread.
  • connection line must be shortened or the radiator must be moved. Both require a considerable amount of work and time.
  • the shortening of the connection lines can usually only be carried out with the help of autogenous welding.
  • the new end of the connection line must be threaded. This is very tedious work, which is made even more difficult by the fact that radiators are usually located in radiator recesses that are difficult to access. In some cases, the free, available lengths of the connecting lines are also limited. The same applies to moving the radiators themselves. Usually, two fitters are required, each of whom takes an average of approx. 1 hour for this work.
  • the object of the invention is to simplify the replacement of radiator valves on radiators by other valves, in particular thermostatic valves.
  • radiator connection plug is rotatably and longitudinally displaceable on the connecting sleeve with the interposition of a seal.
  • the difficulties explained at the beginning no longer occur.
  • the radiator brackets do not need to be loosened, the screw connection on the return remains tightened.
  • a hacksaw or a small cutting disc only the connection grommet is cut through and removed after loosening the union nut.
  • the existing radiator connection plug with the rest of the connection grommet is also unscrewed from the first link of the radiator.
  • the radiator connector plug of the device according to the invention is screwed into the associated opening of the first member of the radiator, and the connecting sleeve is inserted into the radiator connector plug or into the radiator to such an extent that the new valve, in particular the thermostatic valve, easily reaches the free end of the connecting line can be connected.
  • connecting sleeve is advanced in the direction of the new valve until its support flange abuts the assigned connecting piece of the new valve, and the union nut is screwed onto this connecting piece.
  • This work can be carried out by only one technician, who usually does not need more than 15 minutes to do it. There are additional costs for the device itself, but these costs are saved several times by saving labor.
  • the seal between the radiator connection plug and the connection nozzle can also be simple.
  • the radiator connection plug can have a radial flange with a circumferential groove for the seal, preferably an O-ring, arranged on the inner circumferential surface.
  • the device shown is used when the existing radiator valves on radiators are to be replaced by thermostatic valves in the course of energy-saving measures.
  • the device consists of a radiator connection plug 1 with an external thread 2 and a radial flange 3 projecting beyond the external thread 2.
  • the radiator connection plug 1 is screwed into an associated threaded opening of the last link of a radiator (not shown) (radiator) in the usual way.
  • the radiator connection plug 1 has a stepped bore 4, the narrower part 5 of which is located in the region of the radial flange 3 and has about twice the length of the radial flange 3 in the axial direction.
  • a circumferential groove 6 for a sealing ring 7 held therein is arranged on the inner circumferential surface of the narrower part 5.
  • the sealing ring 7 is an O-ring.
  • a connecting sleeve 8 is guided with little play, which is rotatable about the longitudinal axis in the radiator connecting plug 1 and displaceable in the direction of the longitudinal axis.
  • the connecting sleeve 8 has on the threaded side of the radiator connector plug 1 opposite radial bores 9, 10, in which a locking pin 11 is held.
  • the dimensions of the locking pin 11, on the one hand, and those of the larger part of the stepped bore 4, on the other hand, are selected so that the connecting sleeve 8 can be displaced relative to the radiator connecting plug 1 so far that the locking pin 11 rests on the step 12 of the stepped bore 4.
  • a support flange 13 is formed, which is gripped by an inwardly directed flange 14 of a union nut 15 with an internal thread 16.
  • the outer circumference of both the union sleeve 15 and the radial flange 3 are prefabricated in the usual way for the attachment of assigned tools, for example in the form of a hexagon.
  • An existing radiator valve on a radiator is to be replaced by a thermostatic valve, the overall length of which is greater than that of the existing radiator valve.
  • the existing radiator connection plug with the attached connection nozzle is unscrewed from the last link of the radiator.
  • the radiator connection plug 1 of the device shown is screwed into the associated opening of the last link of the radiator.
  • the connecting sleeve 8 is inserted as far as possible or as far as necessary into the radiator connection plug 1.
  • the thermostatic valve with its associated connection piece can be mounted at the end of the connecting line.
