Definitions

  • the present invention relates to a connector for valves intercepting fluids such as hot water and the like, which has, coaxially arranged inside it, a deviating member designed to be rotated through 180° so as to cause channelling of the delivery flow of the fluid towards the associated aperture whatever the direction in which said flow is supplied from the shut-off valve.
  • valves for controlling the flow of the water are also known, said valves being arranged between the supply pipes set inside the flooring or the wall and said radiating elements.
  • valves include those designed for so-called single-pipe systems or systems in which the radiating elements are arranged in series and the return of one forms the delivery for the next one.
  • valves although functional, have a serious drawback, however, consisting in the fact that, during preliminary laying of the pipes, it is essentially not possible to ensure with certainty the same orientation of the delivery pipe and, at the moment when the valve is connected, it may happen that the pipe which emerges from the wall, intended for delivery, is instead the return pipe; in this case, connection of the single-pipe valve causes a flow of hot water which instead of rising upwards enters directly into the radiating element from the bottom, causing only partial heating of the radiator itself with a consequent large amount of energy which is wasted in order to obtain the temperature required in that specific environment.
  • the same phenomenon may also occur in so-called dual-pipe systems in which the radiators are arranged in parallel along two pipes, one of which is the delivery pipe and the other the return pipe. In this case the energy required would be even greater since the still hot water flowing out from a radiator flows out directly into the return pipe which does not supply a downstream radiator.
  • the technical problem which is posed, therefore, is that of providing a connector for valves intercepting fluids, such as hot water and the like, which allows the correct flow of hot water to be maintained, with delivery towards the top part of the radiator and return from the bottom part of the latter, even if the delivery and return pipes should be inverted at the time of laying.
  • said connector should have a simple and low-cost design and should be applicable to all valves of the known type without the need for complicated adaptive measures and should not require substantial modifications at the time of reversal of the flow.
  • a connector for deviating fluids in particular for shut-off valves supplying radiating elements, comprising a body which has, formed in it, at least one supply aperture, at least one delivery aperture and at least one aperture for return of the fluid, said connector having, coaxially arranged inside it, a deviating member capable of being rotated through 180° so as to cause channelling of the delivery flow of the fluid towards the associated aperture, whatever the direction in which said flow is supplied from the valve.
  • a valve 10 for intercepting a heating fluid comprises a body 11 having, formed in it, two apertures 12 and 13 with an axis substantially perpendicular to the longitudinal axis of the valve, into which the pipes 12a and 13a can be inserted, said pipes, in the case of Fig. 1, forming respectively the delivery and the return as indicated by the arrows.
  • Said pipes 12a and 13a are fixed to the valve body using means known per se and only schematically shown as a ring 12b,13b.
  • a third opening 14 supplying the fluid to a radiating body 20 to which the valve is connected via a connector 30 screwed with known means onto the delivery pipe 22, the return duct 23 from the radiator 20 and the valve body 11.
  • a sliding piece 15 is also coaxially arranged inside the valve body 11, said sliding piece being able to perform a translatory movement by means of a usual handwheel 16, causing opening/closing of the valve itself which is in the figures is always shown open.
  • the sliding piece 15 has an internal duct 15a which connects the valve 10 to the connector 30.
  • said connector 30 which is substantially T-shaped, has a first hole 30a which is centred on an axis substantially perpendicular to the longitudinal axis of the valve body 11 and is designed to connect the connector 30 to the pipe 22 for delivery of the fluid to the radiating panel 20, as well as a second hole 30b, being centred on an axis which is substantially parallel, but not coinciding, with said longitudinal axis of the valve body and formed on a segment 30c for reducing the aperture 30d for return of the fluid from the duct 23 of the radiator 20.
  • the connector 30 has, inserted inside it, a deviating member 40 (Fig. 3) formed by a flat body 41 onto which a tubular section 42 is engaged, being cut in the longitudinal direction so as to form an opening 42a; the deviating member 40 is delimited at the front by a semi-circular collar 43 and at the opposite diametral ends of the collar has two teeth 44 which extend outwards and are designed to co-operate with corresponding seats 34 in the connector 30 so as to prevent rotation of the deviating member 40 once it has been inserted into the connector itself.
  • the connector operates in the following manner:
  • the fluid flows out from the duct 23 and, via the hole 30b and the opening 42a of the deviating member 40, is channelled inside the duct 15a of the sliding piece 15 so as to return through the pipe 12a.
