- the respective throttle section 3, 4 has an input section 3.10 or 10.4.
- Each on-off valve 6.1.1-6.1.4 forms two switching elements, in each case a switching element for each of the throttle sections 3, 4.
- the open-close valve 6.1.5 has only one switching element, because it is the Vollbrandventil ,
- the detailed view of the Fig. 5 in that the on-off valve 6.1.1 is formed by a shut-off body 12, a spring 13 acting on the shut-off body 12 and a partition wall 9.1.
- the partition 9.1 separates the channels to the input sections 3.10 and 4.10.
- the Fig. 6 to 9 show the schematic circuit arrangement of the second embodiment of the gas valve unit in different switching positions.
- the input-side surface of the first four open-close valves 6.1.1-6.1.4 is divided by a partition 9.1-9.4.
- the last open-close valve 6.1.5 is not shared with any partition because the output side gas should flow directly to the gas outlet 2.
- the gas inlet 1 is in each case connected to a specific section of the throttle sections 3, 4, in which the gas via the respective open on-off valve 6.1.1-6.1. 5 flows in.
- the throttle sections 3 and 4 comprise inlet sections 3.10 and 4.10, respectively, into which the first open-close valve 6.1.1 opens.
- the further open-close valves 6.1.2-6.1.5 each open into a connection section 3.6-3.9 or 4.6-4.9 of the throttle sections 3 and 4 respectively.
- the transition between the input sections 3.10 or 4.10 and the first connection sections 3.6 or 4.6 and the transitions between adjacent connecting sections 3.6-3.9 and 4.6-4.9 is formed in each case by a throttle point 3.1-3.4 or 4.1-4.4.
- the respective last throttle point 3.4 or 4.4 connects the last connecting section 3.9 or 4.9 with the gas outlet second
- the throttle point 3.4 of the throttle section 3 is closed with a throttle switch 3.5 and connects the last connection section 3.9 with the gas outlet. 2
- the actuation of the open-close valves 6.1.1-6.1.5 takes place in particular by means of a permanent magnet 11 which is displaceable along the row of open-close valves 6.1.1-6.1.5.
- the force for opening the respective on-off valve 6.1.1-6.1.5 is formed directly from the magnetic force of the permanent magnet 11. This magnetic force opens the respective on-off valve 6.1.1-6.1.5 against the spring force of the spring thirteenth
- the Fig. 7 shows the switching arrangement in which the permanent magnet 11 is shifted to the right, that both the first open-close valve 6.1.1 and the second open-close valve 6.1.2 are open. Due to the opened second open-close valve 6.1.2, the gas flows from the gas inlet 1 directly into the first connecting sections 3.6 and 4.6 and from there via the throttling points 3.2-3.4 and 4.2-4.4 to the gas outlet 2. Consequently, this bypasses the gas outlet 2 flowing gas due to the open on-off valve 6.1.2 the first throttles 3.1 and 4.1. The gas flow rate in the switching position according to the Fig. 7 is therefore greater than the gas flow rate in the switching position according to the Fig. 5 and 6 ,
- the gas flow to the first connecting section 3.6 and 4.6 takes place almost exclusively via the second open-close valve 6.1.2. Due to the open-close valves 6.1.1 and 6.1.2, the pressure levels prevailing in the input sections 3.10 and 4.10 are the same as in the first connection sections 3.6 and 4.6. From the input sections 3.10 and 4.10 virtually no gas flows via the first throttle points 3.1 and 4.1 into the first connecting sections 3.6 and 4.6. The total gas flow flowing through the gas valve unit therefore practically does not change when the permanent magnet 11 is moved further to the right in the drawing, thereby closing the first on-off valve 6.1.1 with the second on-off valve 6.1.2 open , By moving the permanent magnet 11 in the drawing to the right, the open-close valves 6.1.3.-6.1.5 are successively opened. As a result, the gas flow rate is gradually increased by the gas valve unit.
- Fig. 8 shows the switching arrangement of the gas valve unit, in which the permanent magnet 11 is shifted to the right, that both the first on-off valve 6.1.1 and the second on-off valve 6.1.2 are open.
- Fig. 7 is the throttle 3.4 closed by the throttle switch 3.5.
- the gas flows from the gas inlet 1 directly into the first connecting section 4.6 and from there via the throttle points 4.2-4.4 to the gas outlet 2.
- the other gas path leads from the open-close valve 6.1 .2 in the first connection section 3.6 of the first throttle section 3 and from there via the throttle points 3.2-3.4.
- the throttle point 3.4 is closed by the throttle line switch 3.5, so that no further gas can flow to the gas outlet 2 via the connecting section 3.9.
- the gas flowing to the gas outlet 2 bypasses the first throttling points 3.1 and 4.1 on the basis of the open on-off valve 6.1.2.
- the gas flow rate in the switching position according to the Fig. 8 is therefore smaller than the gas volume flow in the switching position according to the Fig. 7 ,
- the gas flow to the first connecting sections 3.6 and 4.6 takes place almost exclusively via the second on-off valve 6.1.2.
- Due to the open on-off valves 6.1.1 and 6.1.2 prevails in the input sections 3.10 and 4.10 the same pressure level as in the first connecting sections 3.6 and 4.6. From the input sections 3.10 and 4.10, therefore, virtually no gas flows via the first throttle points 3.1 and 4.1 into the first connecting sections 3.6 and 4.6.
- the total of the gas flow flowing through the gas valve unit therefore practically does not change when the permanent magnet 11 is moved further to the right, thereby closing the first on-off valve 6.1.1 with the second open-close valve 6.1.2 open.
- the switching arrangement of the gas valve unit is shown in the maximum open position.
- the permanent magnet 11 is in its end position on the right side shown in the drawing.
- the last open-close valve 6.1.5 is open at this position of the permanent magnet 11.
- the gas flows directly from the gas inlet 1 into the last connection sections 3.9 and 4.9 to the gas outlet 2.
- the position of the throttle section switch 3.5 does not influence the gas flow in this case.
- Fig. 5 to 9 are the permanent magnet 11 and the components of the open-close valves 6.1.1-6.1.5 coordinated so that when open Gas valve unit either exactly one open-close valve 6.1.1-6.1.5 or exactly two open-close valves 6.1.1-6.1.5 are opened.
- the switching behavior described above can also be achieved by other components and devices, such as mechanical, electrical, pneumatic, hydraulic or their combination.
- both adjacent open-close valves 6.1.1-6.1.5 are briefly opened. This ensures that a switch does not lead to a brief interruption of the gas supply to the gas burner and thus to a flickering or extinction of the flames. With the above-described switching position is also ensured that occurs during a switching and no short-term increase in the gas flow rate. A flicker of the gas flame during the switching process is thus reliably prevented.
- FIG. 10 an embodiment of the gas valve unit. It shows the Fig. 10 in particular the cover plate 14 with integrated sealing composite plate and integrated nozzle plate.
- the seal composite plate may also consist of individual parts, the valve sealing plate, the pressure plate and the lower Gasverediaplatte- are in the Fig. 10 the partitions 9.1-9.8 of eight open-close valves visible.
- the Vollbrandventil 21 has no partition.
- the Fig. 11 shows an exploded view of the seal composite plate 15, the nozzle plate and the upper gas distribution plate 16. It is in Fig. 11 the path 18 of the gas flow from the small fire position 17 to the gas outlet 2 is shown schematically.
- Figure 12 shows the view on the top of the composite gasket plate Fig. 10 .
- the Fig. 13 shows an embodiment of a cover plate 14 with the sealing composite plate 15, the nozzle plate 22 and the upper gas distribution plate 16 of a gas valve unit. It is also possible for the sealing composite plate 15 to be composed of individual parts, for example the sealing plate 15.1, the pressure plate 15.2 and the lower gas distribution plate 15.3. Furthermore, the shows Fig. 13 a screw 19 in the region of the opening of the actuating shaft 20 of the gas valve unit. The screw 19 is set up for Gasartumgna. When the screw 19 to the bolt collar is screwed, seals the underlying membrane seal on the nozzle plate 22 and thus prevents the gas flow over this path.
