Definitions

  • the present invention relates to a radiator with built-in Fittings, according to the preamble of claim 1.
  • the radiators or radiators of the above type are used in the Home heating systems used. You need to get their function in the best possible way Way to be able to be equipped with four valves. This are: the inflow and backflow valve with which the access of the Heating fluid is opened and closed in the body itself; the regulating valve that immediately descends from the inflow valve to regulation of the flow of the warm liquid through the radiator is what to the specific needs of the space to be heated and is adapted to the outside temperature: this valve can be used as a manually adjustable Valve can be made or with thermostatic or thermoelectric Regulation should be overlooked; the relief valve for ventilation of the radiator, which is responsible for its function in the top part of the radiator must be appropriate; the drain valve for the heating fluid, for its functions are located in the lowest part of the radiator.
  • radiators were made to the installer on site equipped with connections, generally threads to close the valves fasten, delivered, that means without the actual valves. It was therefore the job of the installer, the valves in the right place to be installed and after connecting the radiator to the heating liquid flow and radiator filling, the necessary tightness controls of the radiator and the flow regulation.
  • This assembly operation construction was very time consuming and also brought the disadvantage that the work was carried out in rooms with emergency equipment, so that the radiators were often not completely sealed and again later had to be checked.
  • One has therefore tried these disadvantages by producing radiators with partially built-in connections to fix.
  • steel plate radiators are practical known - that is, where the radiator consists of two molded, there is welded sheet metal underneath, which creates a space for form the passage of the warm water and what outer ribs have the function of heat radiation fins - in which a lower inlet connector, which is essential for the radiator to function in single-pipe as well as in two-pipe operation (concepts that are below are better explained, although they are accessible to every professional are suitable, directly through a vertical tube with the regulating valve, which is placed on the top of the same side of the radiator connected is.
  • radiators with built-in valves here speak, but only of radiators with built-in connecting piece.
  • radiators require the installation of another one Intake valve, for example, if you have the radiator without the pipes to empty, to lose weight, an operation that is for replacement or the maintenance of the radiator, for painting the wall behind the radiator or to give the installer the opportunity to use the system to be able to carry out and check before connecting the radiator, can be useful.
  • the above radiators are built in Connection lines between the inlet connector and the regulating valve asymmetrical as they only have this connection on one side and therefore do not allow reverse mounting of the radiator. One must therefore via radiators with right connections and radiators with left connectors have what both the manufacture and the Logistics of such radiators complicates.
  • radiator that has the characteristics of claim 1 corresponds.
  • a similar radiator can in the factory with considerable time savings and greater precision assembled and checked and for insertion in the heating system circuit ready to be shipped. This will result in a significant reduction in time in the assembly on the construction and a remarkable improvement in the Work care achieved.
  • this vertical Connection channel consists of the elements forming the radiator itself and can be indifferent to the right or left side of the radiator are located.
  • this choice only depends on the position in which the individual valves are mounted in the body from and requires no adaptation of the body itself: this is done with a few work steps machined in the factory (four threads in practice) and is shaped like a mirror image compared to a perpendicularly intersecting one vertical plane.
  • radiator forming elements made of die-cast aluminum and are among themselves welded in accordance with the lower and upper chambers.
  • the preferred variant according to claim 4 which provides that at least the inflow, outflow and relief valves, at three of the four corners of the radiator, inside the rectangular frame the radiation wall of the actual body is contained is mainly of an aesthetic nature. even if thanks to this measure a better one Protection of the elements for transport and also achieved after assembly is because these remain hidden behind the wall of the radiator.
  • the regulating valve which is not necessarily intended for that this is behind the bezel of the front panel or front wall of the radiator is concerned, it should be noted that the element in question is also hidden in relation to the connection appears, but in many cases it is useful if this is sideways emerges from the aforementioned edging, be it for a manual adjustment- and then it is useful if these are easily recognized by the worker - be it that it is a thermostat that the Ambient temperature in the most neutral way possible.
  • the claim 5 provides that the inflow valve to its lower chamber by a threaded screw, the axis of which is essentially the same as the axis of the lower channel from the radiator coincides. Thanks to this As a precaution, it is possible to move the radiator around the horizontal Tilt axis of its lower channel without the two connecting pipes (to separate that from the inflow and that from the backflow) because the body of the inflow valve can remain firmly in the room. You get thus, in addition to the advantage already mentioned, the radiator for the To overturn entertainment and cleaning work, including those if a suitable inflow valve is used, the To be able to disconnect the radiator from the hot water pipe without the circuit to have to empty it myself.
  • the inflow valve however have some special properties that matter of claim 6 of the present invention. It is here without Going into the details mentioned that an inflow valve that the Conditions for tilting the radiator around the horizontal axis its lower channel and thus in the radiator of the present invention mountable, satisfactorily fulfilled, is in the parallel patent application of the same applicant No. 00301 / 94.5, on the same day to the Federal Office for intellectual property in Bern, deposited, described.
  • the claim 7 relates to an embodiment of the radiator with coaxial, upper connection threads and lower, also coaxial and mirror images Connection threads, the advantage of which on the one hand the simplified Manufacture of the radiator is because this is only in the four corners pierced and cut with two identical threads and on the other hand that the radiators are free in right or left Position.
  • 1 is a radiator in its entirety, but schematically, in a sectional view, along a vertical central plane.
  • the radiator 1 the basic nature of which is known in the prior art and does not form the subject of the present invention, consists of a plurality of paired, vertical elements, 2,2 ', 2 ", ..., 2 x , each of which is a lower one Chamber 3.3 ', 3 ", ..., 3 x , an upper chamber 4.4', 4", ..., 4 x and a vertical connecting channel 5.5 ', 5 ", ..., 5 x , which connects the two chambers 2.2 ', 2 ", ..., 2 x which correspond to the same element.
  • the lower chambers 3, 3', 3", ..., 3 x are then mutually connected and form a lower horizontal channel 6, while the upper chambers 4,4 ', 4 ", ..., 4 x are mutually connected to form an upper, horizontal channel 7.
  • the mutual connections of the lower chambers 3,3 ', 3 ", ..., 3 x and / or 4,4', 4", ..., 4 x can be carried out in any suitable manner, not shown, such as by threaded bushings, by press mounting, etc. If however, the inventive radiator from Druckg As cast aluminum elements, as provided in an advantageous form of the invention, the mutual connection should preferably be made by welding the contact surfaces of the individual chambers. In any case, this corresponds to the known prior art and need not be described further here.
  • the inflow valve 8 by a threaded screw 16, whose axis x-x essentially with the axis y-y (Fig. 1) of horizontal, lower channel 6 corresponds to which the radiator 1 can thus be tilted without connecting pipes 17 and 18 from the inflow valve 8 to separate the heating fluid to its open, lower one Chamber (in the specific case that 3 on the right) attached.
  • valve 8 shown as an example in its main elements and in simplified form in Fig. 2, shows an inner tube 19 which is screwed into the thread 16 of the element 2.
  • a socket 20 which is connected to the body of the element 2 in a tightly sealed manner by a sealing ring 21.
  • the bushing 20 has a connection for the inflow line 18 of the heating liquid, which subsequently penetrates the distance designated by arrow f 1 into the connecting channel 5 (comparison with FIG. 1).
  • the liquid thus arrives at the regulating valves 10 (FIG. 1), where the flow is regulated according to heating needs, flows through the entire radiator 1 and flows out through the radiator 1 through the lower, horizontal through-channel 6 and the return pipe 17.
  • the inflow valve which is only shown schematically in Fig. 2, but is actually of a complicated nature, since it is provided, for example, with elements for closing the passages 17 and 18, is made in such a way that the radiator can be tilted or rotated about the axis xx of the valve 8, which corresponds to the axis yy of the radiator 1, the above-mentioned advantages are achieved.
  • valve type which is ideal for a radiator applied according to this invention to further advantages of it is to be achieved in the applicant's parallel patent application, deposited on the same day with application number CH 00 301 / 94-5.
  • connections 14, 23 for the inflow 8 and the drain valve 9, or those 24.25 for the regulating 10 and Blow-off valve 11, made of threads connected to the horizontal through-channel the lower liquid 6, or with the horizontal passage channel the upper liquid 7 are coaxial.
  • these are coaxial Connections 14, 23 and 24.25 are mirror images of each other. This characteristic is essential for free installation of the inflow-8 and outflow valves 9, or regulating 10 and relief valves 11, right or left of Radiator 1.
  • the mirror image of the Radiators manufacture them because they are efficient and use can be drilled and tapped using simple tools.
  • the inflow valve 8 is a rotary slide valve, which with the axis its connection is x-x coaxial and one-pipe and two-pipe operation of the radiator allowed.
  • a valve like the one mentioned here is in details described in the applicant's parallel patent application. We refer us here on this description, which is an integral part of the present invention is considered and we therefore waive on discussing this valve here.
  • FIGS. 3, 4 and 5 show the corresponding structural details which are known to every professional and which are not essential for the purpose of the present invention, the regulating valve 10 with regulating head 12, the relief valve 11 and the drain valve 9. It is important to note that the regulating valve 10 and the one for the blow-off 11 are manufactured in such a way that they can be installed on the radiator on the right or left, since the connecting threads of the chambers 4 or 4 x of the elements 2 or 2 x are exactly the same, as is the nature of the whole chamber. On the other hand, as far as the type of valve used is concerned, this is of no importance in the scope of the present invention. 4 shows only as an example that a valve with an automatic opening and equipped with a float 26 has been used as a relief valve.
  • claim 8 relates to a manufacturing and assembly process of the inventive radiator 1. It provides that the inflow-8, Drain 9 and the relief valves 11, as well as the connecting piece 27 (Fig. 3) of the control valve 10 in the workshop on the radiator 1 assembled and calibrated.
