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 type mentioned above are used in residential heating systems. In order to be able to perform their function optimally, they must be equipped with four valves. These are: the inflow and backflow valve, with which the access of the heating fluid into the body itself is opened and closed; the regulating valve, which is used immediately downhill from the inflow valve to regulate the flow of warm liquid through the radiator, which is adapted to the specific needs of the room to be heated and the outside temperature: this valve can be manufactured as a manually regulatable valve or with thermostatic or thermoelectric Regulation should be overlooked; the relief valve for the ventilation of the radiator, which must be installed in the top part of the radiator for its function; the drain valve for the heating liquid, for its functions, is located in the lowest part of the radiator.
  • the inflow and backflow valve with which the access of the heating fluid into the body itself is opened and closed
  • the regulating valve which is used immediately downhill from the inflow valve to regulate the flow of warm liquid through the radiator, which is adapted to the specific needs of the room to be heated and the
  • radiators were supplied to the installer with connections on the building, generally threads to secure the valves, that is, without the actual valves. It was therefore the job of the installer to mount the valves in the correct place and to carry out the necessary checks for the tightness of the radiator and the flow regulation after connecting the radiator to the heating liquid flow and radiator filling.
  • This assembly operation on the construction site was very time consuming and also had the disadvantage that the work was carried out in rooms with emergency equipment, so that the radiators were often not completely sealed and had to be checked again later. Attempts have therefore been made to overcome these disadvantages by producing radiators with partially built-in connections.
  • radiators are known from practice - that is to say those where the radiator consists of two shaped, welded sheets which form an intermediate space for the passage of the warm water and which have outer fins which act as heat radiation fins.
  • a lower inlet connection which is suitable for a function of the radiator in both single-pipe and two-pipe operation (concepts which are explained in more detail below, although they are accessible to any professional), directly through a vertical pipe with the regulating valve, the is attached to the top of the same side of the radiator.
  • radiators require the installation of an additional inlet valve, for example if you want to remove the radiator without draining the lines, a process that is necessary for the replacement or maintenance of the radiator, for painting the wall behind the radiator or even to give the installer the opportunity to run and test the system before connecting the radiator.
  • the above-mentioned radiators with built-in connecting lines between the inlet connection and the regulating valve are asymmetrical, since they have this connection only on one side and therefore do not allow the radiator to be installed in reverse.
  • radiator which corresponds to the characteristics of claim 1.
  • a radiator of the same type can be assembled and tested in the factory with considerable time savings and greater precision and can be dispatched ready for insertion in the heating system circuit. This will result in a significant reduction in time in the assembly on the building and a remarkable improvement in work care.
  • the one according to the invention does not have a separate connecting tube between the lower inflow connection and the regulating valve, but that this vertical connection channel consists of the elements forming the radiator itself and can be indifferent the right or left side of the radiator.
  • this choice only depends on the position in which the individual valves are installed in the body and does not require any adjustment from the body itself: this is machined in the factory with a few work steps (four threads in practice) and is mirror-inverted opposite a vertical plane intersecting it vertically.
  • the elements forming the radiator are made of die-cast aluminum and are welded to one another in accordance with the lower and upper chambers.
  • the elements forming the body have a vertical, flat and continuous radiation wall at least on the side which is to be located on the outside.
  • the regulating valve which is not necessarily intended to be hidden behind the bezel of the front plate or front wall of the radiator, it should be noted that the element in question also appears hidden in relation to the connection, but is in many cases it is useful if it emerges from the side of the border, either for manual control - and then it is useful if it can be easily recognized by the worker - or that it is a thermostat that keeps the ambient temperature in the most neutral way Way to display as possible.
  • the claim 5 provides that the inflow valve to its lower chamber by a threaded screw, the axis of which coincides substantially with the axis of the lower channel of the radiator. Thanks to this provision, it is therefore possible to tilt the radiator around the horizontal axis of its lower duct without having to disconnect the two connecting pipes (the one from the inflow and the other from the backflow), since the body of the inflow valve can remain firmly in the room. In addition to the previously mentioned advantage of being able to tip the radiator for maintenance and cleaning work, this also means that if a suitable inflow valve is used, the radiator can be disconnected from the hot water pipe without having to empty the circuit itself . For this purpose, however, the inflow valve must have some special properties that are the subject of claim 6 of the present invention.
  • the claim 7 relates to an embodiment of the radiator with coaxial, upper connection threads and lower, also coaxial and mirror-image connection threads, the advantage of which on the one hand is the simplified manufacture of the radiator, since it is only drilled in the four corners and cut with two identical threads and on the other hand that the radiators are freely mounted in the right or left position.
  • the manufacturing process of the radiator according to the invention which provides for the assembly of the valves installed in the radiator in the workshop, has practical advantages such as work rationalization and thus. Cost reduction and increased security, and which have already been mentioned several times as purposes of the invention and about which it is therefore no longer necessary to report in more detail.
  • FIG. 1 shows a radiator in its entirety, but schematically, in a sectional view along a vertical central plane.
  • the heater 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 one lower 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 corresponding 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 mutually are 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 in any suitable, not shown, such as by threaded bushings, by press mounting, etc.
  • the inventive radiator consists of die-cast aluminum elements, as provided in an advantageous form of the invention, the mutual connection should preferably be done 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.
  • Valves 8, 9, 10 and 11 are now inventively assembled and tested in the workshop, where it is then possible that practical Reasons for the head 12 of the control valve 10, which is normally removed from the casing 13 of the radiator 1 for reasons already mentioned for packaging and transport and put on the axle and is then fixed in the heating system only after the final assembly of the radiator.
  • practical Reasons for the head 12 of the control valve 10 which is normally removed from the casing 13 of the radiator 1 for reasons already mentioned for packaging and transport and put on the axle and is then fixed in the heating system only after the final assembly of the radiator.
  • the inflow valve 8 is formed by a threaded screw 16, the axis xx of which essentially coincides with the axis yy (FIG. 1) of the horizontal, lower channel 6, around which the radiator 1 can thus be tilted without separating the connecting pipes 17 and 18 from the inflow valve 8 of the heating liquid, attached to its open, lower chamber (in the specific case that 3 on the right).
  • 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 bushing 20 which is connected to the body of the element 2 in a sealing manner by a sealing ring 21.
  • the socket 20 has a connection for the inflow line 18 of the heating liquid, which subsequently penetrates the path 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 depends on Heating needs is regulated, flows through the entire radiator 1 and flows through this by means of 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 primarily used for a radiator according to this invention in order to achieve further advantages from it, is described in the applicant's parallel patent application, filed on the same day with application number CH 00 301 / 94-5.
  • the radiator 1 can be tipped over with respect to the axis y-y of its horizontal, lower chamber without the connecting pipes 17 and 18 having to be disconnected.
  • connections 14, 23 for the inflow 8 and the outflow valve 9, or those 24, 25 for the regulating 10 and relief valve 11, consist of threads which are coaxial with the horizontal passage channel of the lower liquid 6, or with the horizontal passage channel of the upper liquid 7.
  • these coaxial connections 14, 23 and 24, 25 are mirror images of one another. This characteristic is essential for a free assembly of the inflow 8 and outflow valves 9, or regulating 10 and relief valves 11, to the right or left of Radiators 1.
  • the mirror image of the radiators facilitates their manufacture, since they can be drilled and tapped efficiently using simple tools.
  • the inflow valve 8 is a rotary slide valve which is coaxial with the axis of its connection x-x and allows one-pipe and two-pipe operation of the radiator.
  • a valve like the one mentioned here is described in detail in the applicant's parallel patent application. We therefore refer to this description, which is considered an integral part of the present invention, and we therefore refrain from 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 method of the inventive radiator 1. It provides that the inflow 8, outflow 9 and the relief valves 11, as well as the connection piece 27 (FIG. 3) of the regulating valve 10 in the workshop the radiator 1 are assembled and calibrated.
  • this allows the radiator 1, complete with fittings, to be sent to the installer on the building, who has no other task than to unpack it and assemble it on the wall, and to connect the threaded connection piece to the inflow valve 8. It is clear here that this means a substantial reduction in the assembly work on the building and also allows defects and error sources, such as those associated with the hydraulic density or calibration errors, to be eliminated.
