Abstract
A control valve may include a fluid inlet, a plurality of fluid outlets, and a plurality of magnets. One of the plurality of magnets controls fluid flow for each of one of the plurality of fluid outlets. One of the plurality of magnets controls fluid flow for the remaining of the plurality of magnets. When the magnet controlling fluid flow for the remaining of the plurality of magnets is energized, fluid flow is permitted to the remaining of the plurality of magnets. When the remaining of the plurality of magnets are energized, fluid flow is permitted to the respective plurality of fluid outlets.
Claims17
A control valve for a burner, comprising:
- a housing having a fluid inlet and a plurality of fluid outlets;
- a plurality of magnets located within the housing, the plurality of magnets including a first magnet, a second magnet, and a third magnet, the first magnet being located between the second magnet and the third magnet;
- a control panel configured to execute an ignition process of the burner and supply current to energize the first, second, and third magnets between a closed position and an open position, and configured to determine whether a temperature is greater than a set temperature;
- and
- a thermocouple in communication with one of the second and third magnets, the thermocouple being configured to supply current to energize the one of the second and third magnets,
- wherein the second and third magnets control fluid flow to a respective fluid outlet and the first magnet controls fluid flow to the second and third magnets,
- wherein during the ignition process of the burner, the control panel energizes the first magnet and one of the second and third magnets to permit fluid flow to one of the fluid outlets in communication with the burner, which heats the thermocouple and permits the thermocouple to energize the one of the second and third magnets and maintain the one of the second and third magnets in the open position, and
- wherein when the control panel determines that the temperature is greater than the set temperature, the control panel de-energizes the first magnet to terminate fluid flow to the second and third magnets.
A control valve for a burner comprising:
- a magnet regulator having a housing including a plurality of cylindrical apertures, each cylindrical aperture having a first diameter portion that is larger than a second diameter portion;
- a plurality of magnets housed within the plurality of cylindrical apertures, the plurality of magnets including a first magnet, a second magnet, and a third magnet, the first magnet being positioned between the second magnet and the third magnet;
- a control panel configured to execute an ignition process of the burner and supply a current source for energizing each of the plurality of magnets and configured to determine whether a temperature is greater than a set temperature;
- and
- a thermocouple in communication with one of the second and third magnets, the thermocouple being configured to supply current to energize the one of the second and third magnets,
- wherein when the plurality of magnets are not energized, each of the plurality of magnets is in a closed position with the magnet contacting a ledge separating the first diameter portion and the second diameter portion and preventing fluid flow from the first diameter portion to the second diameter portion, and
- wherein when the current source energizes at least the first magnet, the energized first magnet is in an open position with the first magnet being separated from the ledge and permitting fluid flow from the first diameter portion to the second diameter portion, and permitting fluid flow to each of the second and third magnets, and
- wherein during the ignition process of the burner, the control panel energizes the first magnet and one of the second and third magnets to permit fluid flow to one of the fluid outlets in communication with the burner, which heats the thermocouple and permits the thermocouple to energize the one of the second and third magnets and maintain the one of the second and third magnets in the open position, and
- wherein when the control panel determines that the temperature is greater than the set temperature, the control panel de-energizes the first magnet to terminate fluid flow to the second and third magnets.
A method for controlling a burner control valve having a fluid inlet, a plurality of fluid outlets, and a plurality of magnets including a middle magnet and a burner magnet, wherein each of the plurality of magnets includes a head connected to a body with a rod that is slideably attached to the body such that the head and rod move along a longitudinal axis relative to the body from a first position preventing fuel flow from the inlet to one of the plurality of outlets to a second position permitting fuel flow from the inlet to the one of the plurality of outlets, the method comprising:
- energizing the middle magnet and the burner magnet to move the middle magnet and the burner magnet from the first position to the second position to permit fuel flow to the one of the plurality of outlets;
- igniting a burner and heating a thermocouple;
- retaining the burner magnet in the second position when the thermocouple heats, wherein the heated thermocouple energizes the burner magnet;
- determining whether an oven temperature is greater than a set temperature;
- and
- de-energizing the middle magnet to move the middle magnet from the second position to the first position and terminate fuel flow to the one of the plurality of outlets and the burner when the oven temperature is greater than the set temperature.
