  • the figures show basic representations of the fuel-heated heat source and the control valve.
  • the control valve 1 has a housing of a gas pressure regulator, which has a gas inlet opening 3 and a gas outlet opening 4, which leads to a burner 5 of a fuel-heated heat source 6, such as a circulation water heater, flow water heater or boiler or furnace.

  • the burner 5 heats a heat exchanger 12 in the interior 11 of the fuel-heated heat source, which is connected to a flow line 13 and a return line 14 in which a circulation pump 15 is arranged.
  • the supply and return lines are connected to a consumer 16, which can consist of a plurality of radiators lying in parallel and / or in series with one another, possibly also a domestic hot water heater. It may also happen that the water heater is arranged in a parallel branch to radiators and represents a continuous water heat exchanger. In this case, a cold water tap line 17 is present, which is looped through the hot water heat exchanger and is provided with a water switch 18 before it leads to a tap valve 19.
  • a chamber 20 In the area of the housing 2, downstream of the inlet 3, a chamber 20 is formed, in which a valve 21 of a thermoelectric ignition fuse is arranged.

  • the chamber 30 is thus divided by the membrane 29 into two pressure spaces 31 and 32, of which the latter is connected to the outlet line 4.
  • the valve 24/26 is closed in the idle state, that is to say the chambers 22 and 32 are separated from one another.
  • the pressure chamber 30 is connected via a channel 33 to a valve center chamber 34 which is delimited by two valve seats 35 and 36 and an outflow opening 37.
  • a channel 38 leads from the valve seat 36 to a branching point 39, from which a channel 40 leads to the outlet line 4.
  • Another channel 41 leads to a membrane chamber 42, which is connected to the outflow opening 37 via a line 43 in which a valve seat 44 is provided.
  • a valve body 45 corresponds to the valve seat 44, which can be moved in the open position by a compression spring 46 which is supported relative to the housing 2.

  • a valve body 57 which corresponds to a valve seat 58 arranged in the housing, is connected to the membrane 52.
  • the valve seat is connected to the membrane chamber 51 via a line.
  • the valve body 57 is under the action of a compression spring 60, which is supported with respect to the housing 2 and which tends to lift the valve body 57 from the valve seat 58.
  • the valve seat 58 is adjoined by a chamber 61, which has a relatively small cross-section with the membrane chamber 51 via a bore 62 and via a supply air bore 63
  • Air filter 64 is connected to the atmosphere.
  • the chamber 61 Via a suction line 65, the chamber 61 is connected to the suction port of a diaphragm pump 66, which is driven by a motor, not shown, which is supplied with energy via a line 67.
  • the diaphragm pump has a pressure line 68, in which an air filter 69 is arranged and which is connected to the diaphragm chamber 51 via a throttle bore 70.
  • the valve seat 35 is controlled by a valve body 71 which is fastened to a lever 72 and is located in a space 73 which is controlled by the valve seat 35.
  • a valve body 71 which is fastened to a lever 72 and is located in a space 73 which is controlled by the valve seat 35.
  • an electromagnet 74 which is connected to a feed line 75 and which can pull the lever 72.
  • a tension spring 76 is provided which swings the lever about the pivot point 77 into the rest position shown in the drawing.
  • the space 73 communicates with the intermediate chamber 22 via a throttle bore 78.
  • the fuel-heated heat source 6 is connected to a controller 79, to which an outside temperature sensor 81 is connected via a measuring line 80. Furthermore, a temperature sensor 83 is connected via a measuring line 82, which detects the actual value in the flow line 13 prevailing temperature of the heating medium.
  • a line 84 is connected to the regulator, which leads via the regulator to a thermocouple which is assigned to the pilot burner connected to line 23.
  • An output line 85 leads to a switch 86, which is open in the idle state and is assigned to a membrane chamber 87.
  • the line 75, which leads to the electromagnet 74, is connected to the other side of the switch. From the membrane 88 of the membrane chamber 87 two pressure spaces 89 and 90 are separated from each other, which are connected to pressure lines 91 and 92.
  • a switching pin 93 is connected to the membrane 88 and serves to actuate the switch 86.
  • a stowage point 94 is provided, to which two lines 95 and 96 are connected upstream and downstream.
  • the line 95 is connected to the line 91, the line 96 to the line 92, both lines lead to pressure chambers 97 and 98 of a desired pressure sensor 99, which is placed on the membrane chamber 53 and structurally combined with it.
  • the pressure space 97 is formed between a membrane 100 up to the membrane 101.
  • Both membranes are clamped pressure-tight along their edge in the housing, the membrane is pressure-tightly connected to a pin 102, one end of which is one Support plate 103 for the compression spring 54 and the other end of which is formed by a diaphragm plate 104 which is supported on one side of the diaphragm 100.
  • the membrane plate 104 or membrane 100 is connected to the adjusting screw 55.
  • Another output line 105 of the controller 79 is provided with a parallel connection of two adjusting resistors 106 and 107, both of which are connected to the two poles of a changeover switch 108 of the water switch 18.
  • a line 109 leads from the water switch to the branching of the two lines 10 and 67, into each of which an amplifier is installed, the amplification numbers of the two amplifiers differing from one another.
  • the controller If gas is now required on the burner, for example because the temperature sensor 83 has responded, the controller outputs an output signal via line 105. Due to the position of the water switch 18, the value of the resistor 106 is looped into the circuit, so that a certain voltage signal is present at the blower 9 or at the diaphragm pump 66 via the amplifiers on the lines 10 and 67. The blower 9 starts up, at the stagnation point 94 a certain differential pressure signal is generated in the air inlet 7 and is given via the lines 95 and 96 once to the membrane switch 87 and on the other hand to the pressure chambers 98 and 97.
  • the switch 86 is closed so that the control output voltage is applied to the electromagnet 74 via the lines 85 and 75, respectively.
  • the electromagnet pulls the lever 72 against the restoring force the spring 76, so that the valve body 71 lifts off the valve seat 35 and closes the valve seat 36.
  • the gas admission pressure is also present in the valve middle space 34 via the intermediate chamber 22 and the space 73. From there, the pressure is also present in the chamber 30 via the channel 33, whereupon the membrane 29 moves out of the rest position against the restoring force of the spring 27 and thus moves the valve body 26 away from the valve seat 24.
  • the gas pressure is applied to the burner 5 via the outlet line 4, to be precise due to the pressure control of the regulators 44, 46, 48 and 49, to such an extent that a gas flow results which just ignites the entire main burner 5 .
  • the diaphragm pump 66 now starts, a pressure is delayed due to the throttle bore 70 in the diaphragm chamber 51, which pressure is also present in the diaphragm chamber 50 via the throttle bore 110 and strives there to move the diaphragm 47 so that the valve body 45 moves towards the valve seat 44 in the closing direction. This means that the pressure in the valve center space 34 rises, so that the pressure in the chamber 30 also rises, which results in a further opening of the main gas valve 24/26.
  • the controller 79 thus controls a more or less size ren delivery pressure a more or less greater heat output of the heat source. Since the signals for the drive of the diaphragm pump and for the motor of the blower are parallel, the blower delivery rate is adjusted in the time unit to match the larger fuel throughput.
  • the water switch 18 When the nozzle 19 is opened, the water switch 18 is actuated, which switches the changeover switch 108, so that it is no longer the resistor 106 but now the resistor 107 which is looped into the line 105. This means that the blower or the diaphragm pump can be switched to another setpoint that corresponds to the hot water supply.
  • controller 79 continuously reduces the power of the heat source until diaphragm pump 66 stops delivery. If the top output of the burner is still too high, the heat source is shut down completely when the electromagnet 74 is de-energized.
  • thermoelectric ignition fuse A possible switch-off of the heat source by pressing the switch-off button of the thermoelectric ignition fuse is independent of this.
  • the circulating water heater 201 has an outer housing 202, in which a combustion chamber 204 is arranged while leaving an air gap 203 on all sides.
  • the heat exchanger 205 is connected to a flow line 207 provided with a temperature sensor 206, which is connected via a large number of radiators (not shown) to a return line 208, in which a circulation pump 209 is inserted and which leads back to the heat exchanger.
  • the temperature sensor 206 is connected to a regulating and control device 211 via a measuring line 210.
  • the housing 202 is connected to a combustion air exhaust gas line 212 consisting of two coaxial tubes, which consists of an internal exhaust pipe 213 and an outer pipe 215 which is concentric therewith at a distance 214.
  • the interior of the inner tube 213 serves as an exhaust gas path, and its start 216 is preceded by a fan 218 driven by a motor 217, which receives its drive power via a line 219 from the control and regulating device.
  • the suction port of the fan 218 is connected to the interior 220 of the combustion chamber 204.
  • a hot wire anemometer 221 protrudes into the intermediate space 214, the wire of which is connected to the control and regulating device 211 via a line pair 222.
  • This hot-wire anemometer is capable of, due to the preheating of its sensor by a predetermined electrical current, a signal for the air flow through the annular space 214 and the cooling of the sensor by the front to form air stream and to communicate this air throughput as a signal to the control and regulating unit 211.
  • the hot wire anemometer 221 is followed by an adjustable diaphragm 223 which is fastened to the inner jacket of the outer tube 215 and which is more or less able to restrict the free cross section of the annular gap 214. This aperture acts as an adjustable dynamic pressure resistance.
  • a pressure measuring line 224 is branched off from the tube 215 and leads to a pneumatic position transmitter 225, which controls a gas valve 227 via an actuating rod 226, which has proportional actuating behavior, ie the gas throughput released by it is strictly proportional to that Deflection of the pneumatic servomotor 225.
  • the gas valve lies in the course of a gas line 229 feeding a burner 228. The burner is arranged below the combustion chamber 204.
  • the control and regulating device consists on the one hand of a control device for the ratio of air and gas and on the other hand of a controller, for example a flow temperature controller.
  • the regulator could equally well be a capacity regulator, a return temperature regulator, or some other regulator for those in question coming fuel-heated heat source. Control and regulation overlap.
  • a control for the air-fuel ratio is thus superimposed on the regulation.
  • the adjustability of the aperture 223 is used to set the proportional control.
  • pneumatic servomotor 225 It is also possible to give the pneumatic servomotor 225 a different control curve in order to change the proportionality factor. It is essential for the invention that the pneumatic servomotor 225 ensures an instantaneous and hysteresis-free adaptation of the gas throughput to changes in the air throughput. The quadratic dependencies between pressure and flow, on the air and gas side, cancel each other out, so that a linear relationship is created.
