Definitions

  • the present invention concerns a valve assembly adapted for being used in combined plants for providing both heating and sanitary hot water, i.e. residential plants wherein the same heat source, particularly a wall gas-fired boiler, is used for heating both the water for the heat radiating elements (radiators) for heating the rooms, and the sanitary or domestic hot water for various purposes.
  • the same heat source particularly a wall gas-fired boiler
  • the object of the present invention is to overcome the above mentioned shortcomings and limitations and more precisely to provide a valve assembly or group for realizing plants of the above mentioned type, which is formed by two very compact sub-groups, while at the same time providing all the functions requested in these type of plants, both in view of the existing regulations and of technical reasons.
  • Such assembly is further flexible and easily connectible to the other components of the plant, and has quite limited costs, both for its construction and installation.
  • valve assembly for combined plants adapted for providing both heating and sanitary hot water and comprising a gas-fired boiler, a main gas/water of the double action type including an inner circuit and an outer circuit, at least one radiator and a pump for circulating the heating water
  • said valve assembly comprising two sub-groups or valve units mounted on the same support plate, characterized in that the first heating sub-group comprises two sections, communicating through an automatic by-pass valve, the first section comprising a connection for said pump and a connection for the return pipe from the heating plant; the second section comprising a connection connected to the outer circuit of the heat exchanger and incorporating a check valve, and a delivery connection to the heating plant, and in that the second sanitary water distribution sub-group, comprises a connection for the inlet of drinkable water, an outlet connection of the drinkable water and two connections for the inner circuit of the double action heat exchanger, in proximity of one of said connections for the heat exchanger there being provided a depression device, whereas in proximity of the other connection there
  • connections or coupling joints of the assembly according to the invention can be either horizontal or vertical.
  • a communication device with or without a so called disconnector that is formed either as a simple connecting tube or via a disconnecting device.
  • both the sub-groups are formed as integral or single blocks.
  • Fig. 1 is a diagram illustrating the construction of the valve assembly according to the invention connected to a heating plant also supplying domestic hot water, i. e. a plant capable of heating water that circulates in a closed circuit including heat radiating elements, and of supplying upon request domestic hot water for various uses, which plant employs the same heat source, more particularly a gas-fired boiler.
  • a heating plant also supplying domestic hot water
  • i. e. a plant capable of heating water that circulates in a closed circuit including heat radiating elements and of supplying upon request domestic hot water for various uses, which plant employs the same heat source, more particularly a gas-fired boiler.
  • a preferred particular embodiment of the valve assembly and of the components thereof is shown in Figures 2 and 3.
  • the valve assembly according to the invention comprises two sub-groups or valve units that are preferably mounted on the same support plate 29 even when the components are not to be connected to each other ( Figures 2 and 3).
  • the first sub-group also named heating sub-group, is formed by two sections, with a first section comprising a connection 1 connected to a pump P and through this latter to a heat exchanger 20, and a connection 5A also connected to the heat exchanger 20 and incorporating a check valve.
  • connection is used to mean a portion of a coupling joint, such as a flanged member comprising a coupling nut or a threaded spigot.
  • the second section of the first sub-group comprises a delivery connection 8A to be coupled with the heating plant, schematically represented by one element R, and a connection 8 for the return from such heating plant.
  • the section including connections 1 and 8 communicates with the section including connections 5A and 8A through an automatic by-pass valve 30 housed in a connecting portion between the two sections and comprising a pan urged by a spring into a closing position which hydraulically separates the two sections.
  • a valve of this type is disclosed for example in the Italian Utility Model Application No. MI92 U 000 577 filed on June 25, 1992 and its construction and purposes are therefore not further illustrated.
  • connection 9 for a safety valve (not shown) and a connection 4 to an water gauge (not shown) controlling the pressure in the primary circuit.
  • connection 3 for the draining water from the primary or heating circuit
  • a connection 6 for a pressure difference device is provided in the section including the connections 5A, 8A.
  • the second sub-group or sanitary water distribution sub-group comprises a connection 31 for the inlet of drinkable (tap) water connected to the waterworks, and an outlet connection 32 of the drinkable water connected to the domestic sanitary water circuit, that is to the various taps (not shown) of this latter.
  • the sanitary water distribution sub-group further comprises two connections 11A and 12A for the connection to the inner circuit 22 of the heat exchanger 20.
  • a device 16 for manual adjusting the flow rate equipped with a filter 16A and a connection 10 for draining water from the sanitary circuit.
  • a depression device 11 In proximity of the connection 11A there is fitted a depression device 11, in case equipped with a so called Mannesmann regulator for automatically regulating the water flow.
  • a device of this type is disclosed for example in the Italian Patent Application No. MI92 A 000 575 filed on March 3, 1992 and its construction and purposes are therefore not further illustrated.
  • connection 12A Near the connection 12A there is fitted a thermostatic device 12 for tempering the sanitary water when this latter reaches a high temperature.
  • Devices 11 and 12 are connected to each other by a duct 33.
  • a differential pressure flow valve 13 Between the duct 33 and the connection 31 there is fitted a differential pressure flow valve 13 to which a double microswitch 14 is associated.
  • a signal SP from one of the microswitches actuates the pump P, whereas the other signal SVG the microswitches controls the gas erogating valve (not shown).
  • a faucet 15 is provided for supplying water to the heating plant, which is connected either through a tiny tube 36 or a disconnector 38 to the second section of the first sub-group, as shown in Figures 1 to 3.
  • This device is requested by the regulations under some circumstances, and serves to keep separated the sanitary water in the primary (or heating) circuit from the water in the sanitary circuit.
