Definitions

  • the invention relates to a gas valve unit for adjusting a gas burner of a gas appliance, in particular a gas cooking appliance, supplied gas volume flow, wherein the gas valve unit comprises a valve housing and an actuating shaft which protrudes with an operating portion of the valve housing, and wherein in the valve housing, a shut-off valve is formed.
  • Gas valve units of this type are often referred to as secure gas valves.
  • the gas valve unit has a variable opening cross-section, which can be adjusted via the actuating shaft.
  • the opening cross-section can be adjusted continuously. From the opening cross section directly depends on the size of the gas valve unit flowing through the gas flow rate and thus the flame size at the gas burner. As a rule, in the case of generic gas valve units, the opening cross section can be set to zero, that is to say the gas valve unit is completely closed.
  • the gas valve unit has an independent of the setting of the opening cross-section operable shut-off valve.
  • the shut-off valve usually has an open switching position and a closed switching position, but no intermediate positions. When the shut-off valve is closed, the gas flow through the gas valve unit is completely interrupted. On the other hand, the open shut-off valve has no influence on the opening cross-section of the gas valve unit.
  • the shut-off valve serves, on the one hand, to provide redundant safety for complete closing of the gas valve unit. On the other hand, it is possible to automatically actuate the shut-off valve, for example, in response to the signal of a flame sensor.
  • Known gas valve units of the type mentioned are usually designed as a chick valve.
  • the opening cross-section is set in dependence on the rotational position of a plug rotatable in a valve seat.
  • the actuating shaft is arranged coaxially with the chick and connected thereto.
  • the opening cross section of the gas valve unit is made by turning the actuating shaft set.
  • the shut-off valve can be opened by pressing the same actuating shaft.
  • Gas valve units of this type often have an unfavorable switching behavior.
  • the opening cross-section can often be set only inaccurate and not reproducible.
  • the present invention has for its object to provide a generic gas valve unit with improved switching behavior available.
  • This object is achieved in that in the valve housing at least two open-close valves are formed, wherein the open-close valves are actuated by rotating the actuating shaft and the shut-off valve is actuated by axial displacement of the actuating shaft.
  • the open-close valves serve to adjust the opening cross-section of the gas valve unit, and thus the size of the gas flow rate flowing through the gas valve unit. This can be done, for example, by opening and closing the open-close valves one after the other.
  • the control of the open-close valves by turning the actuating shaft.
  • the gas valve unit has an additional shut-off valve, which completely interrupts the gas flow through the valve unit in the closed state.
  • 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 exclusively by opening and closing the open-close valves.
  • the shut-off valve is actuated by axially moving the actuating shaft.
  • both the open-close valves and the shut-off valve can be actuated via the same actuating shaft.
  • each open-valve is associated with exactly one throttle point.
  • the shut-off valve is arranged in the region of a gas inlet of the gas valve unit.
  • 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 against an annular valve seat.
  • the movable shut-off element of the shut-off valve is biased in the closing direction, in particular by means of spring force. As a result, the shut-off valve is always closed in the inoperative state of the gas appliance.
  • the movable shut-off of the shut-off valve is movable by pressing the actuating shaft against the bias in an open position.
  • the pressing movement of the actuating shaft is transmitted directly or indirectly to the shut-off.
  • the shut-off element In the open position, the shut-off element is lifted from the valve seat of the shut-off valve and thereby releases the gas path from the gas inlet of the valve housing in the direction of the open-close valves.
  • the shut-off valve has a magnetic coil with which a force acting in the opening direction can likewise be exerted on the shut-off element.
  • the magnetic coil can be acted upon by, for example, a thermocouple or an electronic controller with voltage.
  • the magnetic coil is designed such that the shut-off element 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 to the open position by means of the force of the magnetic coil.
  • the magnetic coil is coupled to a flame sensor in the region of a gas burner in such a way that the shut-off valve is kept open when a gas flame burns on the gas burner. After extinguishing the gas flame is the Power supply to the solenoid interrupted and the shut-off valve closes automatically by spring force.
  • a deflection device which transmits an axial movement of the actuating shaft in a substantially perpendicular axial movement of the shut-off of the shut-off valve.
  • the direction of movement of the shut-off element is perpendicular to the axial actuating direction of the actuating shaft.
  • the deflection device has a first sliding element, which is arranged on the actuating shaft in the region of the operating section opposite end of the actuating shaft.
  • the first sliding element is moved along with an axial movement of the actuating shaft with this.
  • the first sliding element and the actuating shaft may, for example, be made in one piece.
  • the first sliding element is designed as a first conical element, such 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, since it is rotated about its axis of symmetry.
  • the deflection device has a second sliding element, which is in contact with the first sliding element at least during a pressing of the actuating shaft.
  • the second sliding element slides on the first sliding element.
  • the second sliding element is designed as a second conical element whose central axis is arranged substantially perpendicular to the actuating shaft and whose tip points in the direction of the first sliding element.
  • the formation 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 operation of the deflection device.
  • the first sliding element and the second sliding element are designed and arranged such that an axial displacement of the actuating shaft as a result of a 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 connected to 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 transferred to the shut-off element.
  • the shut-off element of the shut-off valve is thus lifted off its valve seat, thereby opening the shut-off valve.
  • an operating device for the open-close valves is provided, which is coupled by means of a coupling device at an end located within the valve housing end of the actuating shaft to the actuating shaft.
  • the actuator includes, for example, a permanent magnet that can be moved relative to the open-close valves.
  • a rotational movement of the actuating shaft is transmitted by means of the coupling device to the actuator for the open-close valves.
  • the coupling device is designed such that the actuator is rotationally rigidly coupled to the actuating shaft.
  • the coupling device is designed such that an axial displacement of the actuating shaft is not transmitted to the actuator.
  • 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 comprises a flat carrier, which engages in the slot-shaped recess.
  • the engaging in the slot-shaped recess flat driver allows the transmission of torque from the actuating shaft to the actuator of the open-close valves.
  • the compensation of an axial movement the actuating shaft is effected in that the flat driver is more or less inserted 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 region of the control section opposite end of the actuating shaft, such that a tip of the third conical element facing in the direction of the operating portion of the actuating shaft and with a Tip of the first cone-shaped element is connected.
  • the formation 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 during a rotation of the actuating shaft. There is thus no risk of unintentional movement of the second sliding element in that it accidentally contacts the third conical element.
