Definitions

  • the present invention relates to a house heating system where the heat transfer medium is water, said system comprising at least one circulation circuit with a plurality of elements each having two connection conduits which are respectively a supply conduit connected to a mains, and a return conduit.
  • the alternative technique requires presettable radiator valves or return valves.
  • the accuracy of these valves is not such that the desired k v values (valve coefficient values) definitely are obtained.
  • the requisite presetting is neglected, whereby the flow conditions in the system may be drastically changed.
  • US-A-2 249 469 relates to soldered joints between copper tubes and discloses an orifice element which can be permanently assembled in joints of the type in which the pipe is telescoped into the socket of the fitting and secured by solder flowed into the capillary space between the pipe and the internal wall of the socket.
  • US-A-2 244 311 describes a fixed-flow-reducing orifice in steam heating systems.
  • a flow-reducing orifice in the form of a cup-shaped member having a bottom provided with an orifice, a cylindrical side wall portion, and an outwardly extending flange, the member being adapted for insertion in a valve with the flange of the member seated on the valve seat and with the cylindrical side wall portion extending along the valve passage beyond the valve seat, the member being secured in the valve by laterally expanding that portion of the side walls of the member beyond the valve seat.
  • US-A-3 517 700 discloses a compensating element for hydrostatic bearings, said element comprising a jewel disc which is placed in a cylindrical bore by means of two sleeves deforming an elastic ring in which the disc is held in position in a shock-proof manner.
  • the elastic ring is here used to prevent the brittle disc from being crushed under the action of a mechanical shock.
  • DE-A-2 315 195 discloses a plastic nipple with a passage therethrough forming an angle with the horizontal longitudinal axis of the nipple to prevent undesired circulation of water.
  • the present invention has for its object to provide a system of the type referred to by way of introduction, said system obviating the disadvantages encountered in present-day application of the alternative flow control technique.
  • the fixed throttling means By utilizing a fixed throttling means, it is possible to obtain the exact calculated flow. Furthermore, the fixed throttling means also precludes incorrect presetting caused by, for example, a reading error.
  • the concealed mounting makes it impossible for unauthorized persons to interfere with the setting, and all excess consumption of energy can be safely prevented. Moreover, the once-and-for- all throttling by the fixed throttling means is not affected upon exchange of valves, for which reason there is no risk that a correctly made setting will be changed.
  • the throttling means with an outer resilient sleeve, preferably of rubber, a desired damping is achieved of the noise that may arise in the throttling means due to the high flow rate therein and ensuing heavy pressure drops. Further, because of its two-part construction, the throttling means can be adapted to all coupling components available on the market, with relatively few variants of outer and inner sleeves.
  • Fig. 1 shows part of a heating system in which the heat transfer medium is water
  • Fig. 2 shows part of a heating medium system
  • Figs. 3 and 4 are respectively an end view and a longitudinal section of a throttling means according to the invention
  • Figs. 5 and 6 show alternative embodiments of the outer sleeve of the throttling means.
  • the part of the heating system shown in Fig. 1 comprises a radiator 1 having a supply conduit 2 and a return conduit 3.
  • a radiator valve 4 is mounted in the supply conduit, and a fixed throttling means 5 according to the present invention is mounted on the radiator side of this valve 4. More particularly, the throttling means 5 is mounted in a coupling member of the supply conduit, including the usual elbows.
  • Fig. 2 illustrates the mounting of the fixed throttling means according to the invention in a heating medium system.
  • a part of this system includes a heating medium battery 6 having a supply conduit 7 and a return conduit 8.
  • a shut-off valve 9 is mounted in the supply conduit, and a fixed throttling means 5 according to the invention is mounted on the battery side of the said valve 9.
  • the fixed throttling means is concealed in a coupling member of the supply conduits 2 and 7, respectively, in that it is insertable coaxially therein so that it is inaccessible to unauthorized persons.
  • the throttling means comprises an outer sleeve 10 of resilient material, preferably rubber, and an inner, rigid sleeve 11, preferably of brass.
  • the two sleeves 10 and 11 are essentially cylindrical and are provided each with one end flange 12 and 13, respectively.
  • the outer sleeve 10 has an external shape corresponding to the internal shape of the coupling member in which the throttling means is mounted.
  • Alternative embodiments of the outer sleeve 10 to adapt it to difference cross-sectional shapes of the coupling members and elbows available on the market are shown in Figs. 5 and 6.
  • the outer sleeve 10 has a throughpassage for receiving the inner sleeve 11 which has a central hole 14 having an exactly defined flow-controlling cross-sectional area.
  • the hole 14 has the same diameter along its entire length and a sharp edge at the transition to the end surface at the flange 13.
  • the end surface preferably is planar, at least adjacent the hole 14, the length of which is large in relation to the diameter. A length of the order 10 mm and greater has been found to be practically useful.
  • the special design of the hole 14 guarantees an almost completely silent throttling, also at pressure drops as high as 6-8 meters of water column.
  • the throughpassage of the outer sleeve 10 has, independently of the external shape of the sleeve, the same cross-sectional area throughout its length.
  • the exterior shape of the inner sleeve 11 is the same and corresponds to the passage shape of the outer sleeve 10, independently of the size of the precision-drilled hole 14 in the inner sleeve 11.
  • the central hole 14 of the inner sleeve 11 preferably has a cross-sectional area of a value selected from a group of predetermined values. This value is established depending on the desired temperature drop of the heating medium across the radiator, and the pressure available.
  • the inner sleeve may be designed with a selected number of different ky values in the range 0.02-3.00.
  • the number of different details required for the apparatus according to the present invention will thus be equal to the sum of the different types of cross-sectional shapes of the coupling members available on the market and the desired number of different cross-sectional areas of the hole 14.
  • the throttling means may be mounted on the side of the control or shut-off valve facing away from the radiator, but this variant is not preferred.
  • the throttling means may be mounted in the outlet or return conduit, but this usually increases the risk of blocking.
