Definitions

  • the present invention relates to a hydraulic device according to the preamble of claim 1.
  • the invention also relates to a hydraulic appliance and to a hydraulic system, in particular for heating water, comprising said hydraulic device, as well as to a method of operating such a hydraulic system.
  • the present invention especially applies to the field of household water heating systems, wherein the system is used for heating both the household environments and the water used in sanitaryware.
  • These types of systems typically comprise a heating water circuit and a sanitary water circuit.
  • heating circuit can be filled and topped up by manually operating a tap connected to or associated with a water network plumbing, typically the public water distribution main.
  • the flow meter 30' comprises a mobile element 18' and at least one magnetic element 19', which are adapted to generate or modify a magnetic field; the electric detector 21' is adapted to detect said magnetic field; according to the present invention, the electric detector 21' may be a Hall-effect sensor or, alternatively, a Reed sensor.
  • the magnetic element 19' is an element capable of generating or modifying a magnetic field, and may be a permanent magnet, a magnetized element or an element made of ferromagnetic material, or any other element adapted to produce a signal variation in a magnetic sensor.
  • the magnetic element 19' may be fixed or mobile, in particular mounted to or built in the mobile element 18'; moreover, the mobile element 18' itself may be magnetic as well, e.g. it may be at least partly magnetized or made of ferromagnetic material.
  • a hydraulic device according to the invention shown in Figs. 1 to 6, employs an impeller to which at least one permanent magnet is mounted.
  • the hydraulic device 1' is so provided that, in the presence of fluid flowing through it, a magnetic field is generated the value and/or variation of which depends on the fluid flow, in particular on the velocity and/or quantity and/or flow rate thereof.
  • the hydraulic device 1' is adapted to be included in, for example, a water heating system like that shown in Figs. 15 and 16.
  • Said flow meter may however be of any other known type.
  • the outlet duct 7" comprises internally a main duct 11" and a by-pass duct 9".
  • the main duct 11" has an aperture 4"c, or through seat, an aperture 8" and an aperture 40"a which are opened or closed by respective on-off means; in particular, a tap or by-pass valve 3" allows or prevents water flow through the aperture 4"c, while a servo-assisted valve 2", preferably an electrically controlled one, allows or prevents water flow through the aperture 8" and a direct on-off solenoid valve 40", e.g. actuated by an electrothermal element, allows or prevents water flow through the aperture 40"a; the two on-off means 2" and 40" are arranged in series.
  • the respective aperture is preferably small (otherwise too big and strong valve mechanisms and actuators would be needed) and therefore the quantity of water allowed to flow therethrough is small, especially if we consider the supply requirements of a hydraulic system like a household heating system.
  • the fact that there is an additional servo-assisted valve 2" downstream of the direct-on-off valve 40" does not affect the above considerations about the dimensions of the aperture associated with the latter.
  • the by-pass valve 3" is integrated with the main body 4" of the device 1" and comprises a mobile shutter 12" which can slide in a seat 4"c communicating with the duct 9" and can thus stop the fluid flow entering the duct 9";
  • the seat 4"c is a through hole being transversal, in particular substantially orthogonal, to the axis A-A, and is used for housing at least partly the valve 3"; in particular, said hole leads into a chamber immediately upstream of the main duct 11".
  • a second and a third sealing elements 15" and 16 e.g. a gasket or an O-ring; the element 15" provides additional sealing onto the duct 4"c, i.e. works in aid of the element 14"; the element 16" is adapted to prevent any leakage from the by-pass duct 9" to the outside of the device 1".
  • the shutter 12" has a seat 17" for a suitable tool or wrench, such as a screwdriver, in order to allow the tap 3" to be operated, preferably by qualified personnel.
  • a suitable tool or wrench such as a screwdriver
  • the solenoid valve 2" is servo-assisted type and the opening and closing of said solenoid valve takes place through a shutter 10" which is moved by the magnetic field generated within a magnetic core due to electric current running through a coil.
  • the magnetic field thus causes the movement of the shutter 10", on which a rubber piece 20" is mounted which opens and/or closes the aperture 8"; the opening of the passage 8", which is small, determines pressure variations in the chamber housing the core or shutter 10", which variations move a second mobile shutter, i.e. the one in which the passage 8" is obtained, which in turn opens a larger duct; this operation is typical of servo-assisted valves.
  • the movement of the shutter 10" is counteracted by a spring being present inside the magnetic core.
  • this second embodiment example like the first one, would be equally advantageous should the solenoid valve 2" be replaced with a different type of valve, such as a direct on-off valve.
  • a non-return valve 50" is mounted on the outlet duct 7" of the hydraulic device 1".
  • the non-return valve 50 which is known to the man skilled in the art, is of a type comprising at least one hollow cylindrical body 51" inserted in the duct 7" through a respective sealing element or O-ring 53".
  • the valve 50" also comprises an inner shutter 52", e.g. having a substantially “mushroom-like” shape, i.e. comprising a stem which can slide in a central seat of said hollow cylindrical body 51" and an end cap adapted to close a suitable seat, thus stopping the water flow.
  • an inner shutter 52 e.g. having a substantially “mushroom-like” shape, i.e. comprising a stem which can slide in a central seat of said hollow cylindrical body 51" and an end cap adapted to close a suitable seat, thus stopping the water flow.
  • said non-return valve 50" may advantageously comprise some elements, e.g. the hollow cylindrical body 51", obtained directly from the body 4" of the device 1".
  • This solution turns out to be advantageous for several reasons: on the one hand, it reduces the risks of leakage in the contact areas between the main body 4" of the hydraulic device 1" and the cylindrical body 51" of the non-return valve 50", while on the other hand the gasket 53" is no longer necessary (thus reducing the number of components used, and therefore the cost of the device).
  • valve is controlled by an electrothermal shutter.
  • thermoactuator 41 is "pull” type, i.e. when supplied with power it exerts a pulling action towards its own body, although its thermic element is “push” type; of course, the thermic element is suitably oriented for this purpose inside the element 41", in opposition to a reaction element or spring 40"d.
  • thermoelectric element 41 The larger the aperture 40"a, the higher the force that must be exerted by the valve 40" in order to keep the aperture 40"a closed through said contrast spring 40"d adapted to push the shutter 40"b, and therefore the higher the forces to be overcome by the thermoelectric element 41".
  • the aperture 40"a cannot be too large, otherwise it could not be closed by a standard valve 40", thus requiring bigger valves.
  • thermoelectric valve which operates slowly
  • valves of different types may improve safety, because they are subject to different potential causes of failure.
  • the hydraulic device 1" may also advantageously comprise a sensor for detecting a significant parameter of the fluid flowing in the device, e.g. flow rate, temperature, hardness, pressure, etc.
  • a pressure sensor 60" is housed in a seat 60"a located on the outlet duct 7" and is electrically connected, for example, to a system control unit (the wiring harness for the electronic connection between the sensor and the control unit and the control unit itself are not shown for simplicity's sake).
  • the electric signal generated or caused by the pressure sensor 60" can be detected and/or utilized by a control unit, for example, in order to control topping up or filling operations automatically of the system.
  • the hydraulic device 1" is also adapted to be included in a water heating system, as shown in Figs. 15 and 16.
  • the hydraulic device is designated as a whole by reference numeral 1"'.
  • the hydraulic device 1"' bears many conceptual similarities to the device 1", though it features a number of advantageous implementation differences.
  • the hydraulic device 1' comprises two on-off devices 2'" and 40'" arranged in series; however, in this example, they are two electromagnetically controlled solenoid valves (though they may alternatively be both electro thermally controlled valves or different types of valves) of the type being servo-assisted by fluid pressure.
  • the main duct 11"' is subdivided into three sections 11"'a, 11"'b, 11"'c arranged in series.
  • the valve 2"' through the servo-assisted movement of its shutter driven by the core 10"', allows to connect the section 11"'b to the downstream section 11"'c.
  • the valve 40"' through the servo-assisted movement of its shutter driven by the core 10"", allows to connect the section 11"'a to the downstream section 11"'b.
  • the inlet duct 6"' and the outlet duct 5"' are substantially aligned (in particular coaxial) and substantially the same size (a filter applied to the inlet duct 6'" may alternatively be incorporated in the duct itself).
  • the duct 11"' extends in a substantially linear direction being transversal, in particular substantially orthogonal, to the axis of the duct 5"' and/or of the duct 6"', up to the duct 7"'.
  • the body 4"' of the device 1"' there are two seats 4"'a and 4""a adapted to house at least partly the valves 2'" and 40"', respectively.
  • the two valve seats are close side by side, and preferably have an axis which is transversal, in particular substantially orthogonal, to the duct 11"'.
  • the tap seat has an axis being transversal, in particular substantially orthogonal, to the duct section 11"'c.
  • the axes of the seats 4"'a, 4"'b and 4"'c are advantageously substantially parallel to one another; in particular, the tap seat is located on a side opposite to both valve seats.
  • the sensor 60' features very clever mechanical solutions; in fact, it utilizes a cylindrical body from which two ducts come out, in particular two small tubes preferably having a circular cross-section; one tube is associated with the element 61"', while the other is associated with the element 62"'.
  • Said tubes are inserted in two adjacent holes or seats in the body 4"' of the hydraulic device 1"'.
  • the tubes are in communication with the main duct 11'" and with the by-pass duct 9"'; in particular, one duct is in communication with the section 11"'c downstream of the shutter 10'" of the valve 2"" (i.e. with the outlet duct 7"', too), while the other duct is in communication with the duct 9"' immediately upstream of the seat 4"'c of the tap 3"'. Therefore, the two elements 61"' and 62"', which are preferably located in the body of the sensor 60'" in a position close to its outer surface, are able to carry out the above-mentioned pressure measurements.
  • the elements 61"' and 62'" are associated with a support element which may typically be a printed circuit or an electronic circuit; electric connections are then associated with said circuit for carrying the signals of both detection elements out of the body of the sensor 60"'; in Fig. 12, said electric connections are represented by four electric leads, but one may also use a suitable electric connector or welded contacts, or else a different number or type of connections. Additional electric and/or electronic components may be associated with the support element, in particular with the printed circuit; thus, the signals of both elements 61"' and 62'" may, for example, be amplified and/or processed and/or stored (e.g. by a microcontroller or even a simpler circuitry); in such a case, the measurements carried out may also be sent, for example, to an electronic control unit through two electric leads only, e.g. by means of a serial connection.
  • a support element which may typically be a printed circuit or an electronic circuit
  • electric connections are then associated with said circuit for carrying the signals of both detection elements out of the
  • the respective axes shall be substantially parallel. Also, for obtaining a proper arrangement of the sensor 60"', it is advantageous that these axes are transversal, in particular substantially orthogonal, to both the duct 9'" and the duct 11'"; more in particular, said axes shall also be substantially orthogonal both to the axes of the seats 4"'a and 4""a of the valves and to the seat 4"'c of the tap; thus, the sensor body will be positioned on one side of the body 4"' of the hydraulic device.
  • the body of the pressure sensor may also be at least partly built in the body of the hydraulic device.
  • the removable part may be the support (e.g. the printed circuit) of the measurement element(s) (at least during the assembly stage).
  • At least one of the two devices is direct-control type, since this type can ensure the interruption of the flow between the inlet and the outlet even in the presence of anomalous pressures.
  • a non-return valve may nonetheless be used as a safety measure should the solenoid valves fail.
  • the hydraulic device according to the present invention comprises electric connection means for at least the on-off devices; said connection means are so connected that the operation or control of the on-off devices can take place either jointly or separately, in particular through same or respective electric signals.
  • the hydraulic device according to the present invention may advantageously be used, for example, in a gas or electric boiler, typically for domestic use, in order to provide both the filling, in particular the manual filling, and the topping up, in particular the automatic topping up, of the same.
  • Fig. 15 and Fig. 16 the hydraulic appliance is designated by numerals 100' and 100", respectively.
  • the hydraulic device according to the present invention which is a single component, is designated by reference numeral 101, in particular 101' in the case of Fig. 15 and 101" in the case of Fig.16.
  • the devices 101' and 101" are schematized as a solenoid valve and a tap connected together in parallel, and are located essentially in the same position as the flow meter 130.
  • said solenoid valve may advantageously be replaced with two or more valves, e.g. arranged in series, as in the case of the devices 1" and 1"' according to the invention; also, said manual tap may be replaced with an automatic or controlled valve.
  • the device 101 comprises an inlet duct 106, a first outlet duct 105 and a second outlet duct 107, and the flow meter 130 is associated with the first outlet duct 105.
  • the components 101' and 101 in particular their inlet ducts 106' and 106", are respectively connected to the main inlet of the appliance; said inlet is typically connected to the water supply network of the hydraulic system of the house or building, i.e. connected to the water meter through suitable plumbing.
  • household hydraulic systems which generally comprise at least one hydraulic circuit for heating water and at least one hydraulic circuit for sanitary water.
  • the heating circuit is substantially a "closed circuit", i.e. a liquid circulates continuously between a boiler and suitable radiators adapted to heat the environment; the liquid is generally water, with the possible addition of additives, e.g. antifreeze, etc.
  • the sanitary circuit is substantially an "open circuit", in which water (from the public main) flows in, is heated and then flows out through the taps of the house (generally for alimentary or hygienic use); usually a drain is available at each tap for draining the water (e.g. into the public drainage system).
  • the two circuits i.e. the heating and the sanitary circuits
  • the two circuits are substantially independent of each other.
  • the first outlet 105' is connected to the inlet 106' through a duct which is preferably always open; near the outlet 105', there is preferably at least one sensor 130', such as a flow meter; said sensor may however be mounted or connected hydraulically in another location or to another part of the appliance or of the system.
  • the second outlet 107' is connected to the inlet 106' through two fluid flow on-off means connected in parallel, in particular a tap 103' and at least one solenoid valve 102'; preferably at least one non-return valve 150' is associated with the outlet 107'.
  • the device 101' has been described in a very concise manner because detailed descriptions of devices according to the present invention have already been provided above. However, it should be taken into account that the appliance 100' may use different hydraulic devices according to the teachings of the present invention; for example, the hydraulic device employed may be fitted with two solenoid valves in series instead of the single solenoid valve 102' shown in Fig. 15.
  • the appliance of Fig. 15 comprises one section dedicated to the treatment of sanitary water and one section dedicated to the treatment of heating water.
  • the heating water section comprises the respective inlet 191', the respective outlet 192', a fuel burner 171', such as a gas burner, a primary heat exchanger 172', a circulator 175', an expansion tank 176', and a number of connection pipes.
  • the heating water enters the appliance through the inlet 191' (called "return"), flows through the circulator 175', flows through the exchanger 172' (which warms up the water by using the heat received from the burner 171'), and exits the appliance through the outlet 192' (called “delivery").
  • the section for sanitary water comprises the respective inlet 181' (called “main inlet”), the respective outlet 182', and a secondary exchanger 200'.
  • cold sanitary water enters the appliance through the inlet 181' and flows through the exchanger 200', after which hot water exits the appliance through the outlet 182'.
  • the diverting solenoid valve 205' is connected to four pipes. With reference to Fig. 15, the pipe at the top is connected directly to the secondary exchanger 200', the pipe at the bottom is connected to the inlet 191' or heating return of the appliance, the pipe on the left is connected to the circulator 175', the pipe on the right is connected to the exchanger 172'; in said hydraulic connections there are also unidirectional valves 206' and 207'.
  • the heating water circulates not only in the primary exchanger 172' (associated with the burner 171'), but also in the secondary exchanger 200'; thus the heating water is also used for heating the sanitary water, thanks to the secondary exchanger.
  • the heating water In a second operating condition, the heating water only circulates in the primary exchanger 172', not in the secondary exchanger 200'; thus the heating water is only used for the heating system.
