Definitions

  • the present invention relates to a heat exchanger of the radiator type for central heating installation comprising two vertical collectors to which are connected hydraulically several radiant, tubular, regularly spaced elements extending between said collectors preferably, perpendicular to the latter.
  • Radiators known are intended by their collectors to be connected via a long tap and a short connection to the hot water supply line and to the water return line that includes the installation of central heating.
  • Long tap connects with a fitting upper suitable for the upper end of the collector concerned while the tapping is short, through an appropriate lower connector, connects to the lower end of the other manifold.
  • a flow control valve is arranged on the circulation circuit water at the upper connection. By the operation of this tap, it is possible to interrupt the hydraulic circuit in the radiator or to regulate the flow of the water current hot introduced into the radiator.
  • the two taps are made by rigid metal pipes of relatively large section to minimize losses of charges.
  • the value of the difference between the tap fittings must be relatively precise to easily establish the connection with the two collectors. Such precision is incompatible with the nature of the work to be carried out to carry out the tapping and, in the In most cases, the plumber is forced to deform them to achieve the connections. This difficulty of connection can still be amplified by a bad positioning of the radiator suspension elements on the wall. Indeed, these elements determine a second position for the radiator, which may be offset by compared to that determined by the nozzles.
  • the present invention aims to overcome the drawbacks mentioned above not not by increasing the degree of dimensional accuracy in making the taps and in the installation of the suspension elements but by implementing a new type of radiator of a simplified installation, without requirement of precise positioning on the one hand of the two connections relative to each other and to the radiator support elements, and other part of the suspension elements relative to each other and to the radiator.
  • Another object of the invention is the implementation of a radiator whose position after stitching and after installation can be changed.
  • Another object of the present invention is the implementation of a radiator which does not require more for its connection to the central heating circuit, a long connection and a short connection but two short tappings, technically simpler to carry out and in a more economical, which can also be hidden by the radiator which greatly improves the aesthetic aspect of the installation.
  • Another object of the present invention is a radiator whose position of the valve adjustment can be reversed without requiring intervention at the level of two taps.
  • hoses to connect the two collectors to the central heating now allows the radiator to change position and facilitates the realization of these taps since no dimensional precision is required both for the position of the taps with respect to each other than with respect to the suspension elements of the radiator.
  • the use of hoses allows the connection to be easily inverted.
  • collectors at the two taps in order to change the direction of water circulation in the radiator.
  • the first collector constitutes the supply collector and is connected by the connection end corresponding to the supply nozzle, the second collector being connected by the connection end corresponding to the return connection and constitutes the recovery collector.
  • the two conduits of the first collector are both connected to a hydraulic distribution valve having a valve body in which is bored a chamber in which open three through holes made in the valve body, the first and second drilling being in relation to the lower end of the two conduits and the other with the connection end piece, said valve comprising in the chamber a movable element movable between a first position according to which on the one hand, the hydraulic communication between the first tubular conduit and the nozzle connection is ensured and on the other hand the hydraulic communication between the second tubular conduit and the connecting piece is interrupted, and a second position according to which, on the one hand, the hydraulic communication between the first tubular conduit and the nozzle connection is interrupted and on the other hand the hydraulic communication between the second tubular conduit and the connecting piece is established.
  • the movable element of the valve will preferably be placed in the first position when the first collector must be connected to the supply nozzle and therefore constitutes the power collector. However, when this collector is intended to be connected to the return connection and therefore constitute the recovery manifold, the movable element of the valve will preferably be placed in the second position to minimize pressure losses in avoiding the return of water through the first conduit.
  • At the upper connection of the first manifold is associated with a globe valve, intended for the adjustment of the water flow between the first and the second conduit, the valve of said valve being able to be arranged in an interruption position of water circulation between the first and the second conduit.
  • the second collector also consists of a first conduit tubular and a second tubular conduit partially hydraulically connected to each other upper by an upper fitting covering the upper end of each of the conduits, the second duct being hydraulically connected to the radiant tubular elements and the two second manifold conduits both connected to a hydraulic distribution valve comprising a valve body into which is bored a chamber into which open three through holes in the valve body, the first and second holes being in relation with the lower end of the two conduits and the other with the end piece connection, said valve comprising in the chamber a movable element displaceable between a first position according to which on the one hand the hydraulic communication between the first conduit tubular and the connection piece is ensured and on the other hand the hydraulic communication between the second tubular conduit and the connection piece is interrupted, and a second position according to which on the one hand the hydraulic communication between the first tubular conduit and the connection piece is interrupted and on the other hand the hydraulic communication between the second tubular conduit and the connection piece
  • the upper connector consists of a body in which is practiced a cylindrical chamber, open on one of the faces of the body, in which chamber open first and second through holes intended to be brought in and kept in correspondence respectively with the first tubular conduit and the second manifold tubular conduit, a valve seat being provided in the chamber between the mouths of the two through holes, said cylindrical chamber being additionally provided, from its mouth on the face of the body, a thread intended to receive in screwing, according in this case, the threaded end of the blanking plug or the threaded part of an adjustment valve.
  • each collector can receive in turn according to the need of the moment either the adjustment valve or the shutter plug.
  • the manifold can be connected to the supply nozzle the other collector being, of course, connected to the nozzle back. So we see all the flexibility of use that the provisions confer previously defined and in particular those of the valve. So several configurations are possible but it is desirable for optimal use that the water circuit in the whatever its direction, is established for the collector comprising the valve valve adjustment. first in one of its two conduits then in the other, and for the other manifold only in the second conduit to minimize pressure losses.
  • the movable element of the valve By operating the movable element of the valve, it is useful to be able to isolate the two pipes of the collector of the corresponding connection end piece.
  • the movable element of the valve can be positioned by displacement in the chamber valve body, in a fully closed position whereby no communication hydraulic connection is established between the connection piece and the first and second holes of the valve body Thus the two pipes of the corresponding manifold are isolated from the nozzle corresponding.
  • the radiator can therefore be hydraulically isolated from the two nozzles by placing the movable element of each valve according to the third position.
  • the movable element of the valve by displacement in the chamber of the valve body, is positionable in a drain position according to which the first and second holes of the valve bodies are simultaneously hydraulically connected to the connection piece.
  • the positions described above, which the movable element of the valve can occupy, are as it should be stable positions which cannot be modified by the effect of water pressure in the valve.
