Definitions

  • the present invention relates to a bottom-connected control valve and radiator coupling in accordance with the preamble of claim 1.
  • Control valves are known, for instance, from SE-A-75 11022-1 and GB-A-1 221 026 and are constructed for so-called single-pipe systems and dual-pipe or two-pipe systems. Hitherto, the control valves have been connected to the radiators either to a connection welded on the lower edge of the radiator or via pipes and pipe-parts to two screw-threaded connecting stubs on the radiators. According to a more common method nowadays, the inlet and outlet parts of the radiator valve are connected to a riser pipe and welded on the rear side of the radiator with the connecting pipe-stubs of the radiator valve welded in pairs to the rear side of the radiator on the right or the left side thereof.
  • the arrangement is such that the hot water flowing into the radiator and the cooled water leaving the radiator pass through one and the same divided radiator coupling.
  • the connecting stubs are located in pairs on the right or the left side of the radiator in a manner such that hot water is supplied to the radiator through the upper connecting stub whereas the cooled water leaves the radiator through the lower connecting stub.
  • the main object of the present invention is to provide a control valve and radiator coupling in which these drawbacks are totally eliminated. This object is realized in full with the invention defined in the following Claims.
  • FIG. 1 illustrates very schematically the use of a radiator coupling illustrated in the drawings.
  • a coupling is fitted on one side edge of a radiator 1.
  • the illustrated coupling comprises a riser pipe 3 which extends between an upper connecting head 4 and a lower connecting head 5.
  • the two connecting heads 4, 5 each comprise a housing which includes respectively an inner chamber 4' and 5', and an outlet 7 through which heated water V is delivered to the upper part of the radiator 1, and an inlet 8 which receives cooled return water from the lower part of the radiator.
  • the two openings 7 and 8 lie in a plane which coincides with the rear wall of the radiator 1 and communicate with corresponding openings provided in said rear wall.
  • the heads 4, 5 are preferably soldered or welded to the radiator wall, suitably by means of so-called press welding or resistance welding techniques, so as to obtain a liquid-tight seal between the heads and the steel-plate wall of the conventional radiator 1.
  • a control valve 9 which may be a conventional throttle valve or thermostat valve provided with an adjusting knob or wheel 10.
  • the radiator 1 is fitted with the inventive coupling 2 during manufacture and when the radiator is fitted onto a wall the whole of the radiator coupling will thus lie hidden behind the radiator 1 and all that can be seen is the bottom control valve 9 with the adjusting knob or wheel 10 turned to face in the desired direction.
  • Hot water is delivered to the control valve 9 of the Figure 1 embodiment from a pipe 12 and flows into the through-flow chamber 11 of the valve 9 ( Figure 3) via a connecting stub 13 on the control valve.
  • the water sink Subsequent to the hot water delivered to the radiator 1 through the riser pipe 3 having given off heat to the surroundings, the water sinks down in the radiator and exits as cooled return water K to the lower head 5 and to the return pipe 14, via the connecting stub 15, without mixing with the hot water V, i.e. in the absence of any short-circuiting effect.
  • the riser pipe 3 communicates with a sleeve 16 which is arranged in the lower connecting head 5 and which can be selectively connected to one of the two through-flow channels 11' and 11'' of the control valve, these channels being formed by a wall 6 provided in the chamber 11 and dividing said chamber into two mutually separate channels or passageways having the semi-circular area illustrated in the exemplifying embodiment.
  • the pipe 12 is connected with the through-flow channel 11'' and the return-water pipe 14 is connected with the through-flow channel 11'.
  • the sleeve 16 has an inlet 17 which is defined by a semi-cylindrical wall 18 and a flat wall 19.
  • the sleeve 16 can therefore be rotated through 180° and its inlet 17 is displaceable relative to the inlet of the riser pipe 3, so that when the sleeve 16 is rotated through 180°, the inlet 17, which in the Figure 3 illustration lies within the opening of the channel 11'', will be moved so as to coincide with the upper opening of the channel 11', therewith enabling the arrangement to be readily adjusted in accordance with the position of the control or regulating valve 9.
  • the end of the sleeve facing towards the control valve 9 is suitably provided with, for instance, two diametrically opposed projections or locking shoulders 24, 25 which engage in corresponding recesses provided in the inner wall of the lower connecting head 5, and more specifically in the wall of a neck 26 which, as will best be seen from Figure 3, is connected to the control valve 9 by means of a collar nut 28 and an intermediate seal 29.
  • the control valve 9 When wishing to switch the direction of the flow, the control valve 9 is loosened on the lower head 5 of the coupling 2 and the sleeve 16 pulled slightly downwards and turned through 180°, wherewith when rotation of the sleeve is completed the lower edge surface of the flat wall 19 of the sleeve 16 will still lie in sealing abutment with the upper edge surface of the partition wall 6, which is diametrically disposed in the through-flow chamber 11, whereas the semi-cylindrical wall 18 of the sleeve 16 will lie against the left-hand part of the neck 26, as seen in Figure 3, and thus connect the channel 11' with the riser pipe 3. Subsequent to setting the position of the sleeve 6, the sleeve is pushed upwards so as to bring the locking shoulders 24, 25 into locking engagement with the recesses in the neck 26.
  • the flat wall 19 is located in a plane which coincides at least substantially with the centre axis C of the riser pipe 3 and the upper part of the sleeve 16 above the flat wall 19 is cylindrical with the cylinder axis coinciding with the centre axis C.
  • the O-ring 23 is accommodated in an internal groove 22 provided in the sleeve 16, although it is also conceivable to mount the O-ring on the end of the riser pipe 3, optionally in a groove formed in said end.
  • FIG 4 illustrates a coupling for dual-radiator installations and coincides completely with the afore-described coupling with the exception that each head 4, 5 has dual outlets 30, 31 for hot water and dual inlets 32, 33 for cooled water respectively.
  • the coupling illustrated in Figure 5 is connected-up in the manner illustrated in Figure 6, which illustrates two radiators 1' and 1'' with the coupling illustrated in Figure 4 located between and welded or soldered to the mutually parallel and mutually facing surfaces of said radiators.
  • the coupling is preferably mounted centrally between the ends of the radiators and the hot water V is delivered to the upper parts of respective radiators through outlet stubs 30 and 31, while return water K returns through the inlet stubs 32 and 33.
  • the through-flow chamber 11 is divided into two symmetrical, semi-cylindrical channels by means of a flat wall 6. It will be understood, however, that the channels 11' and 11'' may have the form of cylindrical borings in the control valve, wherewith the lower end part 18, 19 of the sleeve 16 is at least configured with a cylindrical inlet adapted to the circular orifices of the two channels. It has also been assumed that the flows are adjusted by rotating the sleeve 16 through 180° around the centre axis C. It will be understood, however, that when the channels have the form of borings, said borings may, naturally, be located at another angular distance. It has also been assumed that the upper, cylindrical end part of the sleeve 16 embraces the end of the riser pipe 3. It will be understood, however, that the end of the riser pipe may embrace the end part of the sleeve.
