Definitions

  • the invention relates to a heating or sanitary installation valve, as well as a sanitary or central heating installation and a radiator comprising at least one such valve.
  • valves serve to regulate the flow of hot or cold water circulating in the pipes, or serve as a flow tap.
  • a valve comprises a valve body, and an internal shutter controlled to close or open the valve body. This internal shutter is controlled by a thermostatic or manual control device.
  • the orientation of the valve is determined by the position of the control device relative to the heater or the sanitary appliance on which the valve is mounted.
  • the thermostatic control device must, in general, extend horizontally.
  • heating appliances or sanitary appliances are fixed near vertical walls, the pipes intended to be connected to the appliance emerging from the ground or from the wall near the appliance.
  • the problem which therefore generally arises is that of connecting the pipe (s) to the valve when neither the orientation of the free end of the pipe nor that of the valve can be changed at will. Indeed, this connection requires a significant assembly time, and the use of connection pieces (elbow, tee, ...) numerous and bulky.
  • connection of a device in parallel to a pipe is generally carried out embedded in the ground or in the walls.
  • a recessed connection poses reliability and safety problems.
  • the invention therefore aims to remedy these drawbacks and its object is to provide a valve for heating or sanitary installation making it possible to modify the orientation relative to the valve body of at least one pipe to which it is connected, and which is also an extremely small footprint and does not require a specific connecting piece.
  • the invention also aims in particular to propose such a valve which comprises a minimum number of parts and with which the assembly is carried out in a simple and rapid manner.
  • the invention also aims to propose such a valve by means of which the connection of the valve in parallel to a pipeline can be carried out directly on this valve.
  • the invention also aims to propose such a valve which is more particularly suitable for connection to at least one pipe made of semi-rigid plastic material such as crosslinked PVC.
  • the invention also aims to propose such a valve which is more particularly suitable for producing a thermostatic valve for central heating installation.
  • the invention also aims to propose a sanitary or central heating installation comprising at least one pipe and at least one sanitary or heating device connected to the pipe without any connection embedded in the ground or the walls.
  • the invention aims to propose such a installation in which the device can be connected in parallel to the pipeline.
  • the invention also aims to propose a central heating installation free of built-in connection, the pipes of which may be of semi-rigid plastic material such as crosslinked PVC, the cost of manufacture and assembly of which is low and the balancing of which can be carried out easily.
  • the invention aims to propose a central heating installation radiator whose assembly and connection to the heating pipes is simple and quick.
  • the invention relates to a heating or sanitary installation valve comprising a valve body and an internal shutter controlled to close or open the valve body, characterized in that the valve body comprises at least one cylindrical portion provided with at least one orifice opening onto the external surface of the cylindrical portion and communicating with the shutter and in that it comprises a sleeve surrounding each cylindrical portion and defining a peripheral circulation chamber bringing each orifice of the portion into communication cylindrical with at least one orifice in the sleeve.
  • the valve body has an internal diaphragm
  • the shutter is controlled in axial translation relative to the valve body to come into contact with the internal diaphragm and close it or to move away from it and open it.
  • the cylindrical portion of the valve body extends on one side and beyond the diaphragm and the shutter is mounted on a shutter support associated with a free end of the valve body. The shutter support is screwed into an internal thread of the valve body.
  • each orifice of the sleeve places the circulation chamber in communication with at least one connection tube intended to be connected to a supply or evacuation pipe for a sanitary or central heating installation.
  • Each connection tube can be bent in the axial direction of the valve body.
