Definitions

  • the invention relates to a gas valve unit for setting a gas volume flow supplied to a gas burner of a gas appliance, in particular a gas cooking appliance, the gas valve unit having a valve housing and an actuating shaft which protrudes with an operating section from the valve housing, and wherein a shut-off valve is formed in the valve housing.
  • Gas valve units of this type are often referred to as secured gas valves.
  • the gas valve unit has a variable opening cross-section that can be adjusted via the actuating shaft.
  • the opening cross-section can be adjusted continuously.
  • the size of the gas volume flow flowing through the gas valve unit and thus the size of the flame on the gas burner depends directly on the opening cross section.
  • the opening cross-section can be set to zero in generic gas valve units, that is to say the gas valve unit can be completely closed.
  • the gas valve unit has a shut-off valve that can be actuated independently of the setting of the opening cross-section.
  • the shut-off valve usually has an open switch position and a closed switch position, but no intermediate positions. When the shut-off valve is closed, the gas flow through the gas valve unit is completely interrupted. The opened shut-off valve, however, has no influence on the opening cross-section of the gas valve unit.
  • the shut-off valve serves, on the one hand, to ensure that the gas valve unit closes completely redundantly. On the other hand, it is possible to operate the shut-off valve automatically, for example as a function of the signal from a flame sensor.
  • Known gas valve units of the type mentioned at the beginning are usually designed as a plug valve.
  • the opening cross-section is set as a function of the rotational position of a plug that can rotate in a valve seat.
  • the actuating shaft is arranged coaxially with the plug and connected to it.
  • the opening cross-section of the gas valve unit is adjusted by turning the actuating shaft set.
  • the shut-off valve can be opened by pressing the same operating shaft.
  • Gas valve units of this type often have an unfavorable switching behavior.
  • the opening cross section can often only be set imprecisely and not reproducibly.
  • the WO 90/12255 describes a control valve with several on-off valves and a shut-off device.
  • the DE 10 2008 027 546 A1 describes a combined valve device with an open-close valve and a so-called bipolar valve.
  • the EP 1 672 279 A1 describes a gas valve for a gas burner with a rotatable valve plug.
  • the invention is a gas valve unit according to claim 1.
  • the present invention is based on the object of providing a generic gas valve unit with improved switching behavior.
  • At least two open-close valves are formed in the valve housing, the open-close valves being operable by rotating the actuating shaft and the shut-off valve being actuated by axially displacing the actuating shaft.
  • the open-close valves serve to set the opening cross-section of the gas valve unit, and thus the size of the gas volume flow flowing through the gas valve unit. This can be done, for example, in that the open-close valves are opened and closed again one after the other.
  • the open-close valves are controlled by turning the actuating shaft.
  • the gas valve unit has an additional shut-off valve which, in the closed state, completely interrupts the gas flow through the valve unit.
  • the shut-off valve In the open state, the shut-off valve has such a large opening cross section that the size of the gas volume flow is determined solely by opening and closing the open-close valves.
  • the shut-off valve is actuated by moving the actuating shaft axially. This means that both the open-close valves and the shut-off valve can be actuated via the same actuating shaft.
  • At least two throttle points each with at least one throttle opening, through which gas can flow depending on the switching position of the open-close valves, are particularly advantageously formed in the valve housing.
  • exactly one throttle point is assigned to each open-close valve.
  • gas can flow through this throttle point; when the on-off valve is closed, the throttle point assigned to this on-off valve cannot be flowed through with gas directly from the gas inlet, but at most via a detour through other throttle points .
  • the shut-off valve is preferably arranged in the region of a gas inlet of the gas valve unit.
  • the shut-off valve When the shut-off valve is closed, there is no gas at any of the open-close valves or at any throttle point. If there are leaks in the area of the open-close valves or the throttle points, gas is reliably prevented from flowing out of these leaks when the shut-off valve is closed.
  • the shut-off valve preferably has a movable shut-off element.
  • the shut-off element can be formed, for example, by an axially movable valve disk which, in the closed state, presses on an annular valve seat.
  • the movable shut-off element of the shut-off valve is preloaded in the closing direction, in particular by means of spring force. As a result, the shut-off valve is always closed when the gas appliance is inoperative.
  • the movable shut-off element of the shut-off valve can be moved into an open position by pressing the actuating shaft against the bias. The pushing movement of the actuating shaft is transmitted directly or indirectly to the shut-off element. In the open position, the shut-off element is lifted from the valve seat of the shut-off valve, thereby releasing the gas path from the gas inlet of the valve housing in the direction of the open-close valves.
  • the movable shut-off element of the shut-off valve can be held in the open position counter to the spring force by means of the force of a magnetic coil.
  • the shut-off valve has a magnetic coil with which a force acting in the opening direction can also be exerted on the shut-off element.
  • the magnetic coil can have voltage applied to it, for example, from a thermocouple or from an electronic controller.
  • the magnetic coil is designed in such a way that the shut-off element, which is already in the open position, can be held in this position by means of the force of the magnetic coil. On the other hand, it is not possible to move the shut-off element from a closed position into the open position by means of the force of the magnetic coil.
  • the magnetic coil is coupled to a flame sensor in the area of a gas burner in such a way that the shut-off valve is kept open when a gas flame is burning on the gas burner. After the gas flame has gone out, the Power supply to the solenoid is interrupted and the shut-off valve closes automatically by means of spring force.
  • a deflection device which converts an axial movement of the actuating shaft into an axial movement of the shut-off element of the shut-off valve that is substantially perpendicular thereto.
  • the direction of movement of the shut-off element is perpendicular to the axial actuation direction of the actuation shaft.
  • the deflecting device preferably has a first sliding element which is arranged on the actuating shaft in the region of the end of the actuating shaft opposite the operating section.
  • the first sliding element is moved along with it.
  • the first sliding element and the actuating shaft can, for example, be made in one piece.
  • the first sliding element is preferably designed as a first conical element in such a way that a tip of the first conical element points away from the operating section of the actuating shaft.
  • the first conical element moves in the direction of its tip.
  • the spatial position of the first conical element does not change because it is rotated about its axis of symmetry.
  • the deflecting device preferably has a second sliding element, which is in contact with the first sliding element at least while the actuating shaft is being pressed.
  • the second sliding element slides on the first sliding element.
  • the second sliding element is preferably designed as a second conical element, the central axis of which is arranged essentially perpendicular to the actuating shaft and the tip of which points in the direction of the first sliding element.
  • the design of the second sliding element as a second conical element has the advantage that the rotational position of the second conical element with respect to its axis of symmetry has no effect on the functioning of the deflection device.
  • the first sliding element and the second sliding element are designed and arranged in such a way that an axial displacement of the actuating shaft as a result of pressing on the operating section is converted into an axial displacement of the second sliding element in the direction away from the actuating shaft.
  • the second sliding element is in operative connection with the shut-off element of the shut-off valve in such a way that an axial movement of the second sliding element in the direction away from the actuating shaft is transmitted to the shut-off element.
  • the shut-off element of the shut-off valve is lifted from its valve seat and the shut-off valve is thereby opened.
  • an actuating device for the on-off valves is provided in the gas valve unit, which actuating device is coupled to the actuating shaft by means of a coupling device at an end of the actuating shaft located inside the valve housing.
  • the actuating device comprises, for example, a permanent magnet which can be moved relative to the open-close valves. A rotational movement of the actuating shaft is transmitted to the actuating device for the on-off valves by means of the coupling device.
  • the coupling device is designed in such a way that the actuating device is coupled to the actuating shaft in a rotationally rigid manner.
  • the coupling device is designed in such a way that an axial displacement of the actuating shaft is not transmitted to the actuating device.
  • the coupling device has a slot-shaped recess on an end face of the end of the actuating shaft opposite the operating section.
  • the coupling device further comprises a flat driver which engages in the slot-shaped recess.
  • the flat driver engaging in the slot-shaped recess allows the transmission of a torque from the actuating shaft to the actuating device of the open-close valves. Compensating for an axial movement the actuating shaft takes place in that the flat driver is inserted more or less far into the slot-shaped recess.
  • the recess is arranged in a base of a third conical element which is formed on the actuating shaft in the area of the end of the actuating shaft opposite the operating section, in such a way that a tip of the third conical element points in the direction of the operating section of the actuating shaft and with a Tip of the first conical element is connected.
  • the design of the end of the actuating shaft as a conical element has the advantage that the spatial extent of a conical element does not change when the actuating shaft is rotated. There is thus no risk of inadvertent movement of the second sliding element as a result of it inadvertently coming into contact with the third conical element.
  • FIGS. 1 to 3 show the switching arrangement of the on-off valves 3 (3.1 to 3.5) and the throttle points 4 (4.1 to 4.5) of the gas valve unit.
  • the shut-off valve according to the invention is not shown here, however.
  • a gas inlet 1 can be seen with which the gas valve unit is connected, for example, to a main gas line of a gas cooking appliance.
  • the gas provided for combustion is present at a constant pressure of, for example, 20 millibars or 50 millibars.
  • a gas line leading, for example, to a gas burner of the gas cooking appliance is connected to a gas outlet 2 of the gas valve unit.
  • the gas inlet 1 is connected to the inlet side of the five open-close valves 3 (3.1 to 3.5) in the present exemplary embodiment via a gas inlet space 9 of the gas valve unit. By opening the open-close valves 3, the gas inlet 1 is connected to a specific section of a throttle section 5 into which the gas flows through the open open-close valve 3.
  • the throttle section 5 comprises an input section 7 into which the first open-close valve 3.1 opens.
  • the further open-close valves 3.2 to 3.5 each open into a connecting section 6 (6.1 to 6.4) of the throttle section 5.
  • the transition between the input section 7 and the first connecting section 6.1, as well as the transitions between two adjacent connecting sections 6.1 to 6.4 are each formed by a throttle point 4 (4.1 to 4.5).
  • the last throttle point 4.5 connects the last connection section 6.4 with the gas outlet 2.
  • the throttle points 4.1 to 4.5 have an opening cross-section that increases in sequence.
  • the flow cross-section of the last throttle point 4.5 can be selected to be so large that the last throttle point 4.5 has practically no throttle function.
  • the open-close valves 3 are actuated by means of a permanent magnet 8, which is displaceable along the row of open-close valves 3.
  • the force for opening the respective open-close valve 3 is generated directly from the magnetic force of the permanent magnet 8. This magnetic force opens the respective open-close valve 3 against a spring force.
  • Figure 2 shows the schematic switching arrangement in which the permanent magnet 8 is shifted to the right in the drawing in such a way that both the first open-close valve 3.1 and the second open-close valve 3.2 are open.
  • the gas flows through the opened second open-close valve 3.2 from the gas inlet space 9 directly into the first connection section 6.1 and from there via the throttle points 4.2 to 4.5 to the gas outlet 2.
  • the gas flowing to the gas outlet 2 bypasses the open open-close Valve 3.2, the first throttle point 4.1.
  • the gas volume flow in the switch position according to Figure 2 is therefore greater than the gas volume flow in the switch position according to Figure 1 .
  • the gas flow to the first connection section 6.1 takes place practically exclusively via the second open-close valve 3.2. Because of the open on-off valves 3.1 and 3.2, the same pressure level prevails in the inlet section 7 as in the first connecting section 6.1. Virtually no gas therefore flows from the inlet section 7 via the first throttle point 4.1 into the first connecting section 6.1.
  • the total gas volume flow flowing through the gas valve unit therefore practically does not change when the permanent magnet 8 continues is moved to the right in the drawing and thereby the first open-close valve 3.1 is closed when the second open-close valve 3.2 is open.
  • FIG 3 shows the schematic circuit arrangement of the gas valve unit in the fully open position.
  • the permanent magnet 8 is in its end position on the right-hand side in the drawing.
  • the last open-close valve 3.5 is open in this position of the permanent magnet 8.
  • gas flows directly from the gas inlet space 9 into the last connecting section 6.4 and only passes through the last throttle point 4.5 on the way to the gas outlet 2.
  • This last throttle point 4.5 can have such a large flow cross-section that practically no throttling of the gas flow occurs and the gas can flow through the gas valve unit in a practically unthrottled manner.
  • Figure 4 shows schematically a structural design of a gas valve unit with a switching arrangement according to Figure 1 to 3 .
  • the shut-off valve according to the invention is also not shown here.
  • valve body 20 in which the gas inlet 1 of the gas valve unit is implemented. Inside the valve body 20 is a gas inlet chamber 9 connected to the gas inlet 1.
  • Shut-off bodies 10 of the open-close valves 3 are guided in the valve body 20 so that they can move up and down in the drawing.
  • Each shut-off body 10 is pretensioned by means of a spring 11 downward in the drawing.
  • each shut-off body 10 can be moved against the force of the spring 11 towards the top in the drawing.
  • the springs 11 press the shut-off bodies onto a valve sealing plate 12, so that the shut-off bodies 10 close openings 12a present in the valve sealing plate 12 in a gas-tight manner.
  • a pressure plate 13 is arranged below the valve sealing plate 12, with openings 13 a which correspond to the openings 12 a in the valve sealing plate 12.
  • the openings 13a in the pressure plate 13 open into openings 14a in a first gas distribution plate 14.
  • a throttle plate 15 with a plurality of throttle openings 18.
  • Each of the Throttle points 4.1 to 4.4 are formed by two throttle openings 18.
  • the two throttle openings 18 belonging to a throttle point 4.1 to 4.4 are each connected to one another by means of the openings 16 a in a second gas distribution plate 16.
  • the openings 14a in the first gas distribution plate connect the throttle openings 18 lying next to one another in two adjacent throttle points 4.1 to 4.5.
  • the last throttle point 4.5 consists of only one throttle opening 18, which opens into the gas outlet 2 of the gas valve unit via a corresponding opening 16a in the second gas distribution plate 16.
  • the permanent magnet 8 With the switch position according to Figure 4 the permanent magnet 8 is in an end position in which all open-close valves 3 are closed. The gas valve unit is thus closed as a whole. The gas volume flow is zero. Starting from this switching position, the permanent magnet 8 is moved to the right in the drawing, whereby the on-off valves 3 arranged below the permanent magnet 8 are opened.
