3,4,5 in parallel is arranged between fuel gas inlet 1 and gas outlet 2.In the case of the restriction without generality, N=3 in Fig. 1 to 4.

Throttling position 3.1-3.4,4.1-4.4,5.1-5.4 that the quantity that corresponding

throttling section

3,4,5 has arranged in series is M.In the case of the restriction without generality, M=4 in Fig. 1.Therefore, first throttle section 3 has first throttle position 3.1, the second throttling position 3.2, the 3rd throttling position 3.4 and the 4th throttling position 3.5.Correspondingly build in second section flowpath segment 4 and the 3rd throttling section 5.Throttling position 3.1-3.4,4.1-4.4,5.1-5.4 have cumulative in order opening section.For example, the opening section at throttling position 3.2 is larger than the opening section at throttling position 3.1 thus.Further, the opening section at throttling position 3.3 is larger than the opening section at throttling position 3.2.Further, the opening section at throttling position 3.4 is larger than the opening section at throttling position 3.3.

In addition the throttling section switch 3.5,4.5,5.5 that,

corresponding throttling section

3,4,5 has for connecting and cut off

corresponding throttling section

3,4,5.

For example, first throttle section switch 3.5 is set up to and connects and cut off first throttle section 3.

In order to manipulate throttling section switch 3.5,4.5,5.5, be especially provided with actuation means (not shown).This actuation means is set up to the definite manipulation profile depending in the multiple predetermined manipulation profiles of combustion gas type selecting to be used for manipulation throttling section switch 3.5,4.5,5.5, and utilizes selected manipulation profile correspondingly to manipulate throttling section switch 3.5,4.5,5.5.

In addition, gas valve unit has the main valve unit 8 that is placed on the main throttling position 7 in throttling section in parallel 3,4,5 and is parallel to

throttling section

3,4,5 layouts.Main valve unit 8 also can be called as main switching mechanism.

In addition, gas valve unit has multiple (M) valve cell 6.1,6.2,6.3,6.4 (M=4).As set forth above, N=3 in Fig. 1.Therefore, each valve cell 6.1,6.2,6.3,6.4 is corresponding has three switch valve 6.1.1,6.1.2,6.1.3,6.2.1,6.2.2,6.2.3,6.3.1,6.3.2,6.3.3,6.4.1,6.4.2, a 6.4.3.For example, the first valve cell 6.1 there is the first switch valve 6.1.1 for manipulating first throttle section 3, for manipulating the second switch valve 6.1.2 of second section flowpath segment 4 and for manipulating the 3rd switch valve 6.1.3 in the 3rd throttling section 5.In general, j switch valve 6.1.1,6.2.1,6.3.1,6.4.1; 6.1.2,6.2.2,6.3.2,6.4.2; 6.1.3,6.2.3,6.3.3,6.4.3 is corresponding is set up to for manipulating j throttling section 3-5, wherein, j ∈ [1 ..., N].For example, the first switch valve 6.1.1 of valve cell 6.1,6.2,6.3 and 6.4,6.2.1,6.3.1 and 6.4.1 manipulation first throttle section 3.

In the example of Fig. 1, three all throttling section switches 3.5,4.5,5.5 cut out.Therefore, stage of switches its without throttling before the main throttling position 7 of flowing through the corresponding component by three

throttling sections

3,4,5 form together.

Throttling section

3,4,5 be combined as domestic gas flexible program.Domestic gas has minimum calorific value and therefore needs maximum flow.

Fig. 2 has shown the schematic changeover module for the first embodiment of gas valve unit natural gas, in switching position.The difference of Fig. 2 and Fig. 1 is as follows: the 3rd throttling section switch 5.5 for the 3rd throttling section 5 is opened.According in the combination of the throttling section 3-5 of Fig. 2, the component of gas flow is only formed by first throttle section 3 and second section flowpath segment 4.

Figure 3 illustrates the schematic changeover module for the first embodiment of gas valve unit liquefied gas, in switching position.According to Fig. 3, first throttle section switch 3.5 cuts out, and second section flowpath segment switch 4.5 and the 3rd throttling section switch 5.5 are opened.Therefore, in the combination of Fig. 3, the component of gas flow is only formed by first throttle section 3.This regulation scheme represents liquefied gas flexible program.

In Fig. 4, first throttle section switch 3.5 is opened, and second section flowpath segment switch 4.5 and the 3rd throttling section switch 5.5 are closed.In this combination, the component of gas flow is formed by second section flowpath segment 4 and the 3rd throttling section 5.This regulation scheme can be used for the burner with larger low combustion power (Kleinbrandleistung), for example, for the burner of natural gas.

Generally speaking, the exemplary changeover module of the gas valve unit of Fig. 1-4 demonstrates by optionally combination valve unit (switching mechanism) with throttling section cocoa selection of land and can repeatedly regulate the predetermined grade for the flow of regulating gas volume flow.

Fig. 5 has shown the schematic changeover module of the second embodiment of gas valve unit.The gas valve unit of Fig. 5 has first throttle section 3 and second section flowpath segment 4.First throttle section 3 has four throttling position 3.1-3.4.Correspondingly, second section flowpath segment 4 has four throttling position 4.1-4.4.Corresponding jointing 3.6-3.9 in first throttle section 3 and the corresponding jointing 4.6-4.9 in second section flowpath segment 4 are exemplarily identified.Corresponding

throttling section

3,4 has entrance zone, threshold zone 3.10 or 4.10.Be provided with five switch valve 6.1.1-6.1.5 in order to manipulate throttling section 3,4.Each switch valve 6.1.1-6.1.4 is configured with two switching mechanisms, that is is applied to mutually the each switching mechanism in throttling path section 3,4.Switch valve 6.1.5 has an only switching mechanism, because it is completing combustion valve (Vollbrandventil).For this reason, the detailed view of Fig. 5 demonstrates switch valve 6.1.1 and is formed by occluder 12, the spring 13 and the dividing plate 9.1 that are applied on occluder 12.Dividing plate 9.1 separates to the passage of entrance zone, threshold zone 3.10 and 4.10.

Fig. 6 to 9 has shown the schematic changeover module of the second embodiment of gas valve unit in different switching positions.The face of the entrance side of four initial switch valve 6.1.1-6.1.4 is corresponding by dividing plate 9.1-9.4 separately.Last switch valve 6.1.5 does not utilize dividing plate separately, because the combustion gas of outlet side should directly flow to gas outlet 2.The definite section that correspondingly connects fuel gas inlet 1 and

throttling section

3,4 by opening switch valve 6.1.1-6.1.5, combustion gas flows in this section by the switch valve 6.1.1-6.1.5 opening accordingly.As set forth above,

throttling section

3 and 4 comprises that entrance zone, threshold zone the 3.10 or 4.10, the first switch valve 6.1.1 is passed in this entrance zone, threshold zone.In other the corresponding jointing 3.6-3.9 or 4.6-4.9 that is passed into

throttling section

3 or 4 of switch valve 6.1.2-6.1.5.At entrance zone, threshold zone 3.10 or 4.10 and first transition parts between jointing 3.6 or 4.6 and the transition part between adjacent jointing 3.6-3.9 or 4.6-4.9 is corresponding is formed by throttling position 3.1-3.4 or 4.1-4.4.Corresponding last throttling position 3.4 or 4.4 connects last jointing 3.9 or 4.9 and gas outlet 2.

The throttling position 3.4 in throttling section 3 can utilize throttling section switch 3.5 to seal, and connects equally last jointing 3.9 and gas outlet 2.

The manipulation of switch valve 6.1.1-6.1.5 especially realizes by means of permanent magnet 11, and it can be along the ordinal shift of switch valve 6.1.1-6.1.5.Directly formed by the magnetic force of permanent magnet 11 at this for the power of opening corresponding switch valve 6.1.1-6.1.5.This magnetic force overcomes the spring force of spring 13 and opens corresponding switch valve 6.1.1-6.1.5.

According in the switching position of Fig. 5 and 6, only open the first switch valve 6.1.1.Combustion gas flows to entrance zone, threshold zone 3.10 and 4.10 and from here at the passage in transit to gas outlet 2 all throttling position 3.1-3.4,4.1-4.4 and all jointing 3.6-3.9,4.6-4.9 by the first switch valve 6.1.1 from fuel gas inlet 1.The minimum power of the given gas burner that is connected to gas valve unit place of amount of Fig. 5 and 6 the combustion gas that flows through gas valve unit.

Fig. 7 has shown changeover module, and therein, permanent magnet so moves right and makes not only to open the first switch valve 6.1.1 but also open second switch valve 6.1.2.Combustion gas flows directly to the first jointing 3.6 and 4.6 from fuel gas inlet 1 by the second switch valve 6.1.2 opening, and flows towards gas outlet 2 by throttling position 3.2-3.4 and 4.2-4.4 from here.Therefore the combustion gas that, flows to gas outlet 2 is because the switch valve 6.1.2 opening walks around first throttle position 3.1 and 4.1.Therefore, being greater than according to the combustion gas volume flow in the switching position of Fig. 7 according to the combustion gas volume flow in the switching position of Fig. 5 and 6.

In fact, only realize the combustion gas inflow to the first jointing 3.6 and 4.6 by second switch valve 6.1.2.Due to switch valve 6.1.1 and 6.1.2 in opening, entrance zone, threshold zone 3.10 with in 4.10, exist as at the first jointing 3.6 and stress level the same in 4.6.From entrance zone, threshold zone 3.10 and 4.10, almost pass through first throttle position 3.1 and 4.1 wakes (nachstr men) in the first jointing 3.6 and 4.6 without combustion gas.Therefore, if permanent magnet 11 continues to move right in drawing and therefore the first switch valve 6.1.1 in the time that second switch valve 6.1.2 opens, close, in fact the combustion gas volume flow that always flows through gas valve unit does not change.In drawing, move right and open in order switch valve 6.1.3-6.1.5 by permanent magnet 11.Progressively improve by the combustion gas volume flow of gas valve unit thus.

Fig. 8 has shown the changeover module of gas valve unit, and therein, permanent magnet 11 so moves right and makes not only to open the first switch valve 6.1.1 but also open second switch valve 6.1.2.Compared with Fig. 7, throttling position 3.4 is sealed by throttling section switch 3.5.

Combustion gas flows directly to the first jointing 4.6 by the second switch valve 6.1.2 opening from fuel gas inlet 1, and flows towards gas outlet 2 by throttling position 4.2-4.4 from here.Another combustion gas path is directed to first jointing 3.6 in first throttle section 3 from switch valve 6.1.2, and is guided through from here throttling position 3.2-3.4.But throttling position 3.4 is sealed by throttling section switch 3.5, thereby make can flow through jointing 3.9 towards gas outlet 2 without other combustion gas.

Towards the mobile combustion gas of gas outlet 2 because the switch valve 6.1.2 opening walks around first throttle position 3.1 and 4.1.Therefore being less than according to the combustion gas volume flow in the switching position of Fig. 8 according to the combustion gas volume flow in the switching position of Fig. 7.Only actually is realized towards the combustion gas of the first jointing 3.6 and 4.6 and being flowed into by second switch valve 6.1.2.Due to the switch valve 6.1.1 and the 6.1.2 that open, entrance zone, threshold zone 3.10 with in 4.10, exist as at the first jointing 3.6 and stress level the same in 4.6.Therefore, from entrance zone, threshold zone 3.10 and 4.10, almost pass through first throttle position 3.1 and 4.1 wakes in the first jointing 3.6 and 4.6 without combustion gas.Therefore, if permanent magnet 11 continues to move right and thus the first switch valve 6.1.1 in the time that second switch valve 6.1.2 opens, close, in fact the combustion gas volume flow that always flows through gas valve unit does not change.

The changeover module of gas valve unit has been shown in the state of opening in maximum in Fig. 9.At this, permanent magnet 11 is located on the sidepiece on the right shown in drawing in its terminal location.Last switch valve 6.1.5 opens in this position of permanent magnet 11.Combustion gas this directly flows to last jointing 3.9 and 4.9 from fuel gas inlet 1 to gas outlet 2.The position of throttling section switch 3.5 does not affect gas-flow at this.

In the example of Fig. 5 to 9, the member of permanent magnet 11 and switch valve 6.1.1-6.1.5 is coordinated so each other mutually, and while opening in gas valve unit or just what a switch valve 6.1.1-6.1.5 opens, or just in time two switch valve 6.1.1-6.1.5 open.Switching characteristic described above also can be realized by miscellaneous part and device, for example, combine to realize with the mode of mechanical type, electric, pneumatic type, fluid pressure type or its.

Be switched to adjacent switch valve 6.1.2-6.1.5 from switch valve 6.1.1-6.1.4 during, temporarily open two adjacent switch valve 6.1.1-6.1.5.Guarantee thus to switch and can not cause temporarily interrupting to the fuel gas supply of gas burner and therefore cause the flicker of flame or extinguish.Utilize switching position described above to guarantee equally not occur equally the raising of the moment of combustion gas volume flow during handoff procedure.Equally therefore, during handoff procedure, prevent reliably the flaring of gas flame.

In addition, Figure 10 demonstrates a kind of embodiment of gas valve unit.At this, Figure 10 has especially shown the cover plate 14 with integrated sealed composite plate and integrated nozzle plate.Sealed composite plate also can comprise separate part, and it is the combustion gas distribution plate of valve seal plate, pressing plate and bottom.In addition in Figure 10, can find out, the dividing plate 9.1-9.8 of 8 switch valves.Completing combustion valve 21 does not have dividing plate.

Figure 11 has shown the decomposition diagram of the combustion gas distribution plate 16 on sealed composite plate 15, nozzle plate and top.At this, in Figure 11, schematically identify the path 18 of gas-flow from low combustion position (Kleinbrandposition) 17 to gas outlet 2.

Figure 12 has shown the view of the upside of the sealed composite plate of Figure 10.

Figure 13 has shown the cover plate 14 of gas valve unit and a kind of embodiment of the combustion gas distribution plate 16 on sealed composite plate 15, nozzle plate 22 and top.Same feasible is that sealed composite plate 15 is made up of independent part, for example combustion gas distribution plate 15.3 of sealing plate 15.1, pressing plate 15.2 and bottom.In addition, Figure 13 has shown the bolt 19 in the region of the opening of the control lever shaft 20 of gas valve unit.Bolt 19 is set up for combustion gas type conversion.When bolt 19 screws in until when bolt flange, the diaphragm seal portion under it is placed on nozzle plate 22 and therefore hinders by the gas-flow in this path.
