Definitions
- the present invention relates to a valve unit for regulating the flow-rate of fuel gas in dependence on the flow-rate of water, particularly for water-heaters, according to the preamble to the main claim.
- a valve unit including these characteristics is known from European patent No. 240394.
- This valve unit in fact has a turbine which is driven by a fraction of the water flow supplied in order to operate an electric-current generator used for lighting a pilot flame.
- the present invention is applicable, in particular but not exclusively, to the field of instantaneous domestic water-heaters in which a fuel gas is supplied to a burner in order to heat water for hygiene purposes.
- a fuel gas is supplied to a burner in order to heat water for hygiene purposes.
- the supply of the fuel gas is arranged to take place only in proportion to a supply of hot water.
- Devices of the so-called "Venturi" type for controlling the flow-rate of the gas in dependence on the flow-rate of water are known for this purpose.
- These devices provide for a reduced cross-section to be inserted in the water supply line so as to generate a differential pressure which acts on the actuator of a valve for regulating the flow-rate of the gas in dependence on the flow-rate of water.
- the actuator is constituted by a diaphragm which is subjected to the differential pressure and is connected mechanically by means of a system of rods to the closure element of the valve regulating the flow-rate of gas by means of a system of rods.
- these devices bring many disadvantages, amongst which is poor efficiency in regulating the flow-rate of the fuel gas, which causes the temperature of the water supplied to vary, alga considerably, with variations in its flow-rate.
- EP0681147 discloses a valve unit, particularly for water-heaters, comprising a gas valve and a turbine including a rotor whose rotation is associated with the flow-rate of water.
- the gas valve is actuated by the axial translation of the turbine caused by hydraulic thrust.
- the rotation of the turbine is further used to supply energy to a safety valve for the burner ignition.
- FR2347597 discloses a valve for controlling the gas flow in dependence of the temperature of the heated water. The valve is actuated by an eddy-current brake driven by a motor.
- the problem upon which the present invention is based is that of providing a valve unit far regulating the flow-rate of fuel gas in dependence an the flaw-rate of water, particularly for water-heaters, which is designed structurally and functionally to overcome the limitations described above with reference to the prior art mentioned.
- This problem is solved by the present invention by means of a valve unit formed in accordance with the fallowing claims.
- valve unit for regulating the flow-rate of a fuel gas in dependence on a flow-rate of water formed in accordance with the present invention.
- the valve unit 1 comprises a hydraulic turbine 2 the rotor 2a of which is housed in a chamber 3 and supported rotatably for rotating about an axis X.
- Inlet and outlet openings indicated 4 and 5 respectively, are provided in the chamber 3 for the connection of the turbine 2 in a line through which the water to be supplied flows.
- the openings 4 and 5 are arranged in a manner such that the rotor 2a of the turbine 2 is rotated about the axis X by the flow of water. It is intended that the turbine may be driven by the entire flow of water treated or by a known fraction thereof.
- An eddy-current brake is associated with the turbine 2 and comprises an annular body 7 made of electrically conductive material, preferably aluminium or copper, extending coaxially from only one side 2b of the rotor 2a and a magnetic field generator such as a permanent magnet 9, coaxial with the annular body 7 and also supported rotatably in the valve unit 1 for rotating about the axis X.
- the annular body 7 and the permanent magnet 9 are housed, respectively, in a first chamber 8 formed in the chamber 3 and in a second, hydraulically separate chamber 10 which thus communicates neither with the chamber 3 nor with the first chamber 8.
- the first chamber 8 preferably extends coaxially around the second chamber 10 housing the permanent magnet 9, so that the wall separating the chambers is thin.
- the valve unit 1 also comprises a regulation valve 11 inserted in a duct 12 through which the fuel gas flows, for modulating the flow-rate thereof.
- the valve 11 includes a closure element 13 mounted on one end of a rod 14 which in turn is connected to the permanent magnet 9 by transmission actuator means 15.
- the actuator means 15 are of the type with gears and comprise a pinion or sprocket 16 keyed to a shaft 16a extending axially from the magnet 9.
- the pinion 16 is meshed with a rack 17 formed on the rod 14.
- the rod 14 is disposed along an axis Y substantially perpendicular to the axis X of the pinion 16 and the rack 17 is constituted by teeth extending peripherally around the rod 14.
- the closure element 13 is movable along the axis Y between a closure position, in which it is in abutment with a respective seat 19 to prevent the flow of gas along the duct 12, and an open position in which it is removed from the seat 19.
- This movement is opposed by a spring 20 a first end of which is in abutment with a shoulder 13a formed on the closure element 13 so as to urge the closure element 13 against the seat 19.
- the valve unit 1 performs its function of controlling the flow-rate of the fuel gas in dependence on the flow-rate of water in the terms indicated briefly below.
- This action of the eddy-current brake is regulated owing to the fact that, in a conductor which is subjected to a variation in magnetic induction flux, electrical currents are created which tend to oppose the variation in flux.
- the rotary motion of the annular body 7 about the permanent magnet 9 creates, in the body 7, induced currents the electromagnetic field of which opposes this relative motion, tending to "drag" the magnet 9 along with it.
- the closure element 13 is moved along the axis Y in opposition to the spring 20, away from the seat 19, allowing the gas to flow.
- the position reached by the closure element 13 is defined by the equilibrium between the resilient force of the spring 20 tending to close the closure element 13 and the torque generated by the eddy-current brake.
- the greater is the torque generated by the brake the greater is the degree of opening of the closure element 13 and hence the greater is the flow-rate of fuel gas.
- valve unit 1 is intended to be fitted on an instantaneous water-heater with a pilot flame.
- the valve unit is therefore also provided with a thermoelectric valve 21 for shutting off the fuel-gas duct 12, with actuator means 22 for manual opening of the thermoelectric valve, and with an auxiliary pilot-flame supply duct which is not shown in the drawings but which branches off the duct 12 in a position between the thermoelectric valve and the regulation valve.
- thermoelectric valve 21 is disposed upstream of the regulation valve 11 and preferably in a position substantially parallel thereto.
- the functional characteristics of the thermoelectric valve 21 provide, in conventional manner, for a capability of its closure element 23 to be held in a position in which the fuel gas circuit is open by means of an internal electromagnetic circuit controlled by a pilot-flame presence indicator, for example, a thermocouple.
- closure element 23 which would no longer be held by the electromagnetic circuit, would be moved to the closure position by resilient means 24 so as to shut off the duct 12 for supplying the fuel gas to the burner of the water-heater.
- the actuator means 22 for manual opening of the thermoelectric valve 21 comprise a push-button 25 which is disposed outside the valve unit 1 and to which first and second parallel pressure elements, extending inside the valve unit and indicated 26 and 27, are fixed.
- the first pressure element 26 is arranged as an extension of the closure element 23 of the thermoelectric valve, and the free end of the second pressure element 27 is in abutment with the end of the spring 20 remote from the closure element 13 of the regulation valve.
- the push-button 25 is pressed against the valve unit, thus moving the closure element 23 partially into the electromagnetic circuit of the thermoelectric valve, by means of the first pressure element 26.
- the fuel gas can flow to the auxiliary duct in order to supply the pilot flame without, however, being able to reach the burner through the regulation valve 11.
- the closure element 13 is in fact closed against the seat 19 by the spring 20 which, during this operation to move the push-button 25 is further compressed by the second pressure element 27.
- the present invention thus overcomes the limitations described above with reference to the prior art mentioned, at the same time offering many advantages.
- a first advantage is constituted by the complete and total hydraulic separation between the water and gas circuits.
- Another advantage consists of the true proportionality of the regulation of the gas in dependence on the flow-rate of water and, not least, it should be borne in mind that the regulation is ensured by inexpensive operating means which are reliable over time.
