Definitions

  • the present invention relates to a hydraulic Coupling for connecting the radiators of a heating system, according to the preamble of claim 1.
  • the radiators of a heating system are becoming common today connected to two pipes, one for the liquid inflow and one for the backflow, which is a little piece from the wall or ceiling stepping out.
  • the two pipes are generally without a closing valve, that is, it is usually impossible to use the heating fluid let in the cycle, if not before all provided radiators installed or at least each tube with a dedicated, sealed lid has been closed.
  • An installation system is state of the art a heater known that at least the installation the radiator tries to simplify.
  • CH-A-676146 is a mounting and connecting device for a radiator to be attached to a wall known who during the Installation carried out in the phase of building shell construction is first attached to the wall so the pipe system can be laid appropriately. After that the radiator is removed again so that the Prefabricated works (plastering, painting, etc.) can be executed. After that is intended, a hydraulic coupling in the form of a concrete Can be used to which the inflow and outflow a heating circuit can be connected. The can is through a cover with two holes for the front Connection pipes to the radiator closed.
  • This device is an aid to the assembly of the View supply and return pipes. Be here first the radiators at the desired locations of the room, so that already one final choice is made via their location and, after this choice, the arrangement of the pipes in the floor and / or determined in the ceiling.
  • the connections ending in the box are Connections without closing valves, that is, the Heating circuit cannot with water or other Liquid should be replenished, if not all Radiators have been connected.
  • the tin is one concreted in the wall Junction box.
  • EP-A-544028 is a radiator connection element for hot water central heating systems described in which the forward and return of a Heating circuit connected by a connecting channel is, the connecting channel through a socket in Forward and reverse is blocked.
  • the socket is operated by the water flow. At this document is therefore neither valves nor one Operation of a closure from the outside, so that here too there is no possibility of If not, fill the heating circuit with water all radiators are connected to the circuit.
  • the purpose of the present invention is to implement a heating system that the User of the Apartment or house the possibility offers, the radiator depending on special equipment needs and the necessary heat output.
  • the basic idea of the present Accordingly, invention is not simplification the heating system, but a adaptable to the needs and wishes of the user Realize heating system. Act in particular it is about giving the owner of the apartment a composable Heating system with hydraulic coupling available to which the individual radiators are connected can be, similar to this with sockets that for connecting the various devices to be supplied are provided.
  • the hydraulic ones distributed in the room Couplings prepared so that they can be used at any time can record a radiator that matches the two normal ones Connection pipes (inflow and return flow) connected to it becomes.
  • What is new here is compared to the known one mentioned above State of the art the fact that the connection of each Pipe through a valve provided with a closure, which is normally closed and therefore the outflow prevents fluid from circulation if no radiator is connected to the valve, and the can be opened automatically when a radiator is connected to the valve itself.
  • the valve opening is carried out in a manner known per se, that is, in that the connecting pipe of the radiator moves the valve closure from its locking seat and the valve opens.
  • the two inflows and check valves for an increased degree of freedom of the user beneath them with a lock Connection channel connected.
  • This clasp can close the connection channel completely or completely or open partially so that the realization of a Heating system on request according to the one-pipe or two-pipe principle is made possible.
  • the latter two, concepts known to those skilled in the art quite simply that in the first case the whole of the inflow pipe liquid must flow through the radiator, before it can flow out through the reflux pipe, while in two-pipe operation only a part of the feed pipe Liquid flows through the radiator and the other Part directly through a by-pass into the return pipes flows.
  • the inventive Arrangement therefore offers the advantage of flexibility both for the user - because he is thus free, the to choose the most comfortable position of the furniture - as well as for the installer who is single-pipe or two-pipe depending on the general installation conditions and under Taking into account the need for the best level of performance to achieve the entire system.
  • FIG. 1 shows an inventive hydraulic coupling, consisting of a box concreted in the wall 2 1 (shown in section in FIG. 1).
  • Box 1 is provided with a lid 3, visible in Fig. 2, the it closes from the outside.
  • the lid 3 of the box 1 acts outside like a completely closed surface.
  • a groove along which the material breaks when it is subjected to a suitable machine force which, although not shown, two holes in shape and location through which then the two connections that connect the coupling to the radiator. Only one of these two holes is visible in FIG. 2, designated 5.
  • the lines 6 and 7 are through two conventional nut screw connections 8, 9 and two inner bushings 10, 11 provided with seals, each connected to a connection of a valve 12, 13.
  • valve 12, 13 shown here with closure is state of the art per se; against it is new here the application in connection with the junction box, what constitutes the inventive hydraulic coupling.
  • Each valve 12, 13 is made out two connections 14, 15 and 16, 17 (in FIG. 1 is only the cross section through the valve 12 visible, however corresponds to the valve 13) with thread-cutting Screw that forms an angle of 90 ° with each other, so that the outlet port 15 is approximately halfway up the lid 3 of the can 1 protrudes.
  • the outflow connection 15 of the valve 12 and those at 17 of the valve 13 include then a closure 18, 19 (in Fig. 2 is only the closure 18 visible) existing from a mushroom-shaped locking disc 30, which in a inner socket 21 of the connector 15 slides.
  • a spring 22 pushes the sealing disc 20 against the stop device 23 and closes, thanks to the sealing ring 24 with which the disc 20 is provided, the outflow connection 15 tightly.
  • line 6 becomes like the entire inflow line the heater, filled with pressurized heating fluid, which presses on the back of the locking disc 20 and so the effect of the locking spring 22 is increased.
  • the inventive hydraulic coupling is content but not by establishing a quick connection with the inflow and form return lines, the installer wants offer the system another advantage, that is that between a one-pipe and two-pipe operation of the Plant to choose.
  • the invention provides that the two Valves (12, 13) below themselves through a connecting channel 29, provided with a closure to be operated from the outside 30 connected are.
  • the closure 30 is a smaller one Piston manufactured by means of a through the normally duct opening 29 closed with a cover 32 inserted hexagon wrench in the channel 29 is screwed in.
  • the channel 29 can be completely closed (as in Fig. 1 shown) or partially or completely opened will.
  • the whole is in the coupling 1 of the pipe 6 flowing liquid into the inflow pipe 25 flow from the connected radiator and through the Flow back pipe 26 (see FIG. 4) to pass through to flow out the coupling through line 7. This is the typical case of a system with two-pipe operation.
  • the protruding connection pipes 25 and 26 through the cover 3 on the front side of the hydraulic coupling 1 is a preferred form of the present Invention. How to do that in the figures See example 1 and 2, are the two Valves 12, 13 manufactured so that the corresponding Connections 14, 15 and 16, 17 at an angle of Form 90 °, which allows lines 6 and 7, horizontally to protrude from the coupling as tubes 25 and 26.
  • the axis of the connecting channel 29 (which in Fig.2 corresponds to the plane of the cross section B-B) in arranged essentially in one plane, which is the axes of the two inflow and return flow lines 6 and 7 contains.
  • the can 1 from die-cast Plastic material is made and that the same is concreted into the wall 2 so that its cover 3 is essentially flush with the wall. Furthermore, the Lid 3 a lid without holes, but the incisions 33 (see FIG. 2a) in agreement with the zones in which the two second connections are located 15 and 17 of the valves 12 and 13 are located.
  • the box 1 according to a preferred form of the invention square and the width / height is between 6 and 15 cm, while the depth of the can, that is, that in the Part cast in concrete, preferably between 3 and 7 cm.
  • the inventive hydraulic coupling is for the realization of heating systems in residential and business premises particularly suitable.
  • the attachment and connection of the Radiators 39 and 40 are designed according to the above been made by the incisions 33 in the lids 3 of the corresponding couplings 36 and 38 broken and the Connecting pipes 25 and 26 plugged into the radiators 39.40 were. With this short operation, being for the radiators 39 and 40 a suitable holder is provided, is the installation of the radiators on the couplings 36 and 38 ended. If another tenant later the installation of the radiator on the coupling 37 of the installation should prefer coupling 38, it would be sufficient if the pipes 25 and 26 of the radiator 40 from the coupling 38 would be pulled away, whereby the closures 18 and 19 of the corresponding valves 12 and 13 immediately the pipes Close off 25 and 26 and thus any liquid escapes would avoid from circulation. The substitution the location of the radiator of coupling 38 through the Coupling 37 (after replacing the two covers between the two couplings) could therefore function properly the heating system that would remain operational continuously happen.
  • the individual radiators 39, 40 to the hydraulic couplings 36, 37 and 38 through pipes 25, 26 can be connected with thread-cut connections, where the pipes are then thermoformed and made from, for example Brass-made elbow connections 41 (Fig.3) can, or rigid, right-angled pipes, such as the pipe shown in Fig.2, or flexible, wrapped Metal pipes 42 (Fig.4), or other flexible rubber pipes with steel mesh cover 43 (Fig. 5).
  • Brass-made elbow connections 41 Fig.3
  • rigid, right-angled pipes such as the pipe shown in Fig.2, or flexible, wrapped Metal pipes 42 (Fig.4), or other flexible rubber pipes with steel mesh cover 43 (Fig. 5).
  • the advantages of the inventive solution are how already mentioned in part, in the possibility that the Installer can realize a heating system without primarily about the definitive location of the Radiators to take care of and at the same time that the Users of the apartment or the room have a wide range of options for the attachment of the radiators depending on the Equipment of the room are given.
  • the solution is also very rationally realizable, and it allows a lot quick interventions in a system that has already been executed, for example, to carry out maintenance work or damaged To replace radiators without interrupting system operation to have to.
