Definitions

  • the invention relates to a valve arrangement for selectively switching on and shutting off a secondary line, which opens into a main line of a fuel-fired heat generator carrying a fuel / air mixture controlled composition, and a fuel line assigned to the secondary line, via which a time constant is proportional to the air flow rate in the secondary line Amount of fuel is supplied, which corresponds to the fuel / air ratio in the mixture carried in the main line.
  • This patent application describes a device for regulating the output of fuel-fired, in particular gas-fired, heat generators, in which a fuel / air mixture is supplied to the heat generator via a main line, the composition of which is regulated by supplying the main line with a predetermined, time-constant fuel quantity and the air throughput in the main line is adjusted by means of a blower, the delivery rate of which is controlled by means of a control device as a function of the output signal of a flow sensor arranged in the main line and possibly further variables influencing the optimal fuel / air ratio.
  • the fuel / air mixture supplied to a burner via the main line therefore determines the minimum output of the heat generator.
  • the known device additionally has at least one secondary line through which an additional amount of fuel / air mixture can be supplied.
  • the invention has for its object to provide a valve assembly that allows the simultaneous connection or shutdown of a secondary line and the fuel line assigned to it and is characterized by simple structure and high reliability, so that they are also for use in heat generators of relatively low power can be used and thus makes such heat generators suitable for use in areas with relatively low heat requirements, such as in heating systems for single-family homes or even flats.
  • valve arrangement according to the invention When using the valve arrangement according to the invention, there is no need to install separate valves both in the secondary line and in the associated fuel line and, if necessary, to connect them to a common drive and also to provide special fittings such as T-pieces or the like in order to connect the fuel line with the Merging the secondary line and then the secondary line with the main line, since the valve arrangement according to the invention fulfills both the functions of two shut-off valves and the line mergers. In addition, there is no longer any need to connect two separate valves to a common actuator. Therefore, the valve arrangement according to the invention enables a significant simplification of the construction and a reduction in the space requirement of fuel-fired heat generators of the type described. The elimination of devices for coupling two separate valves simultaneously increases the operational safety and reliability of such a heat generator.
  • the application of the valve arrangement according to the invention is particularly advantageous if not only a sudden increase in the heating power by completely switching on the secondary line and the associated fuel line is desired, but a more or less constant change in the heating power, because in a further embodiment of the invention the mouths of the The secondary line and the fuel line have cross sections which are proportional to one another and the slide can be able to be brought into intermediate positions in which it releases or covers equal parts of the orifice cross sections. Since the throughput of the air supplied via the secondary line as well as the via the fuel line supplied fuel is proportional to the cross-section of the mouth, by changing the cross-sections of the mouth, the amount of such a mixture supplied in addition to the fuel / air mixture conveyed by the main line can be changed more or less continuously.
  • the slide is adjustable step by step, and the mouth of the fuel line is formed by a number of bores, one of which is released or covered at each step of the slide adjustment. If the mouth of the secondary line has a rectangular cross-section, the throughput of the secondary line is exactly proportional to the travel of the slide. In this case, either the mouth of the assigned fuel line can also have a rectangular cross-section, or all holes can have the same diameter when using holes.
  • the main line forms a chamber with an arcuate wall section at the point where the secondary line opens and the slide is designed as a rotary slide valve.
  • Rotary slide valve arrangements are particularly easy to manufacture and allow simple storage and particularly simple drive of the slide valve.
  • the fuel line can then open within the sector of the chamber defined by the mouth of the secondary line in a flat floor perpendicular to the circular wall section and the slide can have a spring-loaded insert resting on the floor. This design also leads to a particularly simple and space-saving construction.
  • the chamber can be formed in a particularly simple manner completely by a cylindrical pot that is open at one end, into the jacket of which, in addition to the secondary line, the section of the main line leading to an air inlet opening also opens, while the section of the main line leading to the burner of the heat generator is attached connects the open end of the pot.
  • a particularly space-saving arrangement results when both the section of the main line opening into the jacket of the chamber and the secondary line are formed by pipe sections with a rectangular cross section and these pipe sections abut one side.
  • a further simplification of the system for heat generation provided by means of such a valve arrangement is achieved if, in a further embodiment of the invention, the fuel line also opens into the bottom pot, which supplies the fuel quantity required to form the fuel / air mixture guided by the main line. It is then no longer necessary to install special fuel lines for the main line and the secondary line, but a lonely fuel line can be used, which is connected to the pot and opens into the pot with openings, one of which, which cannot be covered, opens the gas throughput for determines the amount of air required by the main line, whereas one or more other openings are assigned to the secondary line and, like the mouth opening of the secondary line, can optionally be covered or released by the slide.
  • the bottom of the pot can be formed by a disk in which there is an annular channel to which a common fuel line is connected and which is connected to the interior of the pot through openings which connect the mouths of the fuel lines assigned to the secondary line and the main line form.
  • the bottom of the chamber also permits the bearing of a shaft which is sealed off from the bottom and to which the slide is fastened inside the chamber and whose end penetrating the bottom is connected to a drive motor.
  • the heat generator shown in the drawing has a burner 1, to which a gas / air mixture is supplied via a main line 2, 2 '.
  • the burner 1 is located within a boiler housing 3, which also encloses the heat exchanger 4 of a heating system.
  • the boiler housing 3 is provided with a vent 5 for the flue gases, in which there is a fan 7 driven by a motor 6.
  • the main line 2, 2 ' connects the burner 1 to an air inlet opening 8.
  • a temperature continues to protrude into the section 2 of the main line sensor 9 and a flow sensor 10 into it.
  • the output signals of these sensors 9, 10 are fed to a control device 11.
  • a fuel line 13 opens into the main line 2 and supplies gas to the main line as fuel.
  • a gas pressure regulator 14 is located in the fuel line 13 in the flow direction of the gas, so that the main line 2, 2 'is supplied with the gas at a predetermined pressure and therefore also a predetermined amount.
  • the specified amount of gas includes a precisely determined amount of air.
  • the supply of the correct amount of air is monitored by the flow sensor 10, the output signal of which is characteristic of the flow velocity of the air in section 2 of the main line.
  • the control device 11 controls, depending on the output signals of the temperature sensor 9 and the flow sensor 10, the speed of the motor 6 which drives the fan 7 in such a way that the flow rate required to supply the correct amount of air prevails in section 2 of the main line. This ensures in a very simple manner that optimal combustion conditions are present for the gas supplied to the burner 1.
  • a secondary line 21 is connected in parallel with the main line 2, 2 'and opens into the main line 2, 2' in the area between the sensors 9, 10 and the burner 1. Similar to the main line 2, 2 ', the secondary line 21 also has an open end serving as an air inlet opening 22, and a fuel line 23 is also assigned to it, which branches off from the fuel line 13 opening into the main line 2, 2'.
  • a shut-off valve 24 is located in this fuel line 23.
  • a shut-off valve 25 is also located in the secondary line 21.
  • the shut-off valves 24 and 25 are connected to a common servomotor 26 which, if necessary, causes the shut-off valves 24, 25 to open and close together.
  • the check valves 24, 25 schematically shown in FIG. 1 for the secondary line 21 and the associated fuel line 23 are integrated in a valve arrangement which has a cylindrical pot 31, in the jacket 32 of which the Air inlet opening 8 leading section 2 of the main line and the secondary line 21 open.
  • both lines have the same rectangular cross-section in the exemplary embodiment shown and are arranged parallel to one another in such a way that they abut one side 27 and 28, respectively.
  • the section 2 ′ of the main line leading to the burner 1 connects to the open end of the pot 31.
  • the end of the pot 31 opposite the section 2 'of the main line is provided with a bottom 33 into which an annular channel 34 is incorporated.
  • the base 33 consists of two disc-shaped parts 35, 36, of which the upper part 36 has a groove forming the annular channel 34 on its side facing the lower part 35.
  • the lower disc-shaped part 35 is provided with a screw connection for the gas line 13, so that the gas line 13 opens into the annular channel 34.
  • This ring channel 34 communicates with the interior of the pot 31 via bores 37 and 38, of which the bore 37 is arranged in front of the mouth of section 2 of the main line and has a diameter such that the amount of gas entering the pot via this bore 37 corresponds to the minimum output of the burner, to which the amount of air flowing through the main line 2, 2 'is adjusted by means of the sensors 9, 10.
  • the bores 38 are arranged within the sector 39 delimited by dash-dotted lines in FIG. 2, which is defined by the mouth 40 of the secondary line 21 in the jacket 32 of the pot 31, and next to one another on a circular arc 41, likewise indicated by dash-dotted lines.
  • the bores 38 in their entirety form the fuel line 23 assigned to the secondary line 21.
  • the total cross section of these bores 38 is dimensioned such that the amount of gas supplied to the pot 31 via these bores is in the same ratio to the amount of air supplied via the secondary line 21 as that above the amount of gas supplied to the bore 37 to the amount of air supplied through the section 2 of the main line.
  • the amount of gas supplied via all of the bores 38 and the corresponding amount of air supplied via the secondary line 21 can be dimensioned such that the maximum output of the burner 1 is achieved together with the fuel / air mixture which is always carried by the main line 2, 2 ' .
  • the section 2 of the main line and the secondary line 21 leading to the air inlet opening 8 have the same cross section, so that the entirety of the bores 38 has the same cross section as the bore 37 and the heating power of the burner 1 is doubled by switching on the secondary line 21 can be.
  • a rotary slide valve 51 serves as shut-off valves 24, 25 for the secondary line 21 and the associated gas line 23, which is fastened on the inner end of a shaft 52 which is rotatably mounted in the base 33 and is sealed against the base in a manner not shown is.
  • This rotary slide valve has at its end a plate 53 which is circular in cross section and which in a first end position covers the mouth 40 of the secondary line 21 and thus blocks the secondary line 21.
  • the rotary slide 51 In its section connecting the plate 53 to the shaft 52, the rotary slide 51 has a bore 54 perpendicular to the bottom 33 of the pot, in which a stamp-like insert 55 is mounted displaceably and is loaded by a helical compression spring 56 arranged in the bore 54, so that the latter Insert with the outer surface of his head 57 abuts the bottom 33.
  • the diameter of the head 57 is dimensioned such that it completely covers the bores 38 arranged on the circular arc 41 when the plate 53 covers the mouth 40 of the secondary line 21.
  • the rotary valve 51 By pivoting the rotary valve 51 by an angle which is substantially equal to the angle of the sector 39 defined by the mouth 40 of the secondary line 21, the rotary valve 51 can be brought into a second end position, not shown in the drawing, in which the plate 53 the mouth 40 and also the head 57 of the insert 55 clears all the bores 38. If the rotary valve occupies a position lying between these two end positions, the mouth 40 of the secondary line 21 is only partially released.
  • the use of tubes with a rectangular cross section has the result that the mouth 40 of the secondary line also has a rectangular cross section and the released section of the secondary line is exactly proportional to the swivel angle of the rotary valve.
  • the use of a number of bores 38 as the mouth of the fuel line assigned to the secondary line 21 ensures that the amount of gas supplied is proportional to the number of bores released and thus in turn to the swivel angle of the rotary valve. It is advisable to gradually adjust the rotary valve so that each additional hole is completely released or covered. If a completely constant change in the heating output is desired, the row of holes could be replaced by a corresponding slot. It would also be possible to partially cover a larger bore similar to the mouth of the secondary line, in which case such a bore would correspond to a circular mouth of the secondary line. With regard to a linear dependence of the change in power on the angle of rotation, however, the described embodiment with a rectangular mouth of the secondary line and a correspondingly shaped mouth of the associated fuel line is preferred.
  • the drive motor 26 for the rotary valve 51 which corresponds to the two shut-off valves 24, 25 according to FIG. 1, is fastened to the base 33 of the pot 31 by means of a holder 61 such that the output shaft 62 of the motor with the rotary valve 51 supporting shaft 52 is aligned and can be connected to this shaft by a plug coupling 63.
  • the motor 26 can be a stepping motor, but it can also be a continuously running motor with appropriate control, which preferably has a strong reduction, since the rotary valve 51 may only be adjusted at a relatively low speed. Since the air throughput is determined by the delivery rate of the blower 7, the change in the line cross-sections and thus the fuel supply must not take place faster than the speed with which the blower 7 can react to the changed air requirement.
  • the invention is not limited to the exemplary embodiment shown, but deviations from it are possible without leaving the scope of the invention.
  • the cylindrical shape of the pot is only important for the pivoting range of the rotary valve, so that even when using a rotary valve, the chamber formed by the pot can also have a different cross-sectional shape, as long as only the secondary line into a cylindrical one Wall section opens and there is enough space to swing the rotary valve away.
  • a linearly movable valve can also be used and that it is possible to provide the mouths of the air and gas lines in the same wall section.
