Definitions
- This constructive provision refers to the registration of. gas with flame monitoring device applied to stoves, which was given the following constructive arrangement, with a view to optimizing the cost of production and, maintaining its functionality according to technical standards, by; mounting the valve core directly to the registration body without the need for a single magnet; By subset of the flame monitoring device be fixed by plastic deformation of the registration body, without the need for nuts, sealing and.
- a secondary selector (17) which modifies the flow to suit the characteristics of the gas being used, optimizing the release according to its calorific value (natural gas or liquefied petroleum gas); its secondary selector is capable of being rotated by a Philips screwdriver from the front of the cooker by removing only the register handle without the need to disassemble the entire upper part of the cooker; no watertight selector is required.
- gas stoves have in their burners flow registers controlled by the respective pushbuttons provided on the front panel of the appliance, enabling the opening, closing and adjustment of the passage quantity. gas to the burners, resulting in high and low flames, and in some cases supervisory devices. flame.
- the flame monitoring device comprises the registration, a mechanical (manual) two-way valve, spring return, and plunger retention by a magnetic field from. a coil energized due to the generation of electrical energy from the heating through the burner flame in a thermocouple. When the heating is interrupted by flame extinguishing, the electric energy that is no longer generated. keep the valve open.
- gas enters the selector that in the open position, transits through the connecting hole opened by the magnet piston to the burner supply outlet, or enters through and through the flame monitoring device chamber. to the selector through the connection hole, exiting to the burner through the hole.
- the register In the closed position, the register remains watertight for both the environment and the burner by means of the magnet plunger obstructing the through hole and also the selector, whether provided with elastic sealing element or by metal / metal adjustment. .
- these registers may be provided with a second hand-operated selector that modifies the flow rate to suit the characteristics of the gas being used, optimizing the flow rate according to its calorific value (gas natural gas -GN, or liquefied petroleum gas-LPG).
- FIG. 1 - Shows a perspective view of the gas register with flame monitoring device, object of the present patent.
- FIG. 2 - Shows a longitudinal section view of the gas register with. flame monitoring device, illustrating the flame monitoring device when closed.
- the register remains watertight for both the environment and the burner by obstructing the hole with the plunger of the flame monitoring device,
- FIG. 3 - Shows a longitudinal sectional view of the gas monitor with flame monitoring device, illustrating the flame monitoring device when opened.
- To open the gas passage turn the rod counterclockwise and push it to the end of its stroke, simultaneously igniting the flame in the burner. Gas will enter from the flame monitoring device chamber to the selector through the connection, exiting to the burner through the hole.
- FIG. 4 - Shows a cross-sectional and angled view of the gas monitor with flame monitoring device illustrating that perpendicular to the outlet port is a seat for engaging a secondary selector whose front end is chamfered and positioned in the direction of the hand-operated selector orifice in the selector, which modifies the flow to suit the characteristics of the gas being used, optimizing the flow according to its calorific value (natural gas or liquefied petroleum gas) .
- FIG. 5 - Shows a perspective view of the main selector, part, integral of the gas register with flame suppressor device
- FIG. 6 - Shows a perspective view of the two subsets of the supervisor device. part of the gas register with flame monitoring device.
- FIG. 7 - Shows a perspective view of the log. gas with flame monitoring device, illustrating that perpendicular to the selector shaft there is a hole (19) which exposes the teeth of the secondary selector head.
- the "FLOW SUPERVISOR GAS REGISTRATION PROVISION” used for domestic cookers and the like comprises a rod (1) which. it pierces a lid (2) and subsequently drives a spring-surrounded pin (3), pierces a washer (5) and lodges and pierces inside a selector (6), which fronts a channel (7) and peripheral longitudinal channels (8), which, in turn, is housed within the front gallery contained in the body (R) and a body, until the lid is secured to the perimeter of the opening, and the end of the pin (3) frontally, the hole (9) contained within the body (R).
- This record has two subsets (10) consisting of a coil (11) provided with only one.
- a spring-loaded plunger (12) such a housing-free or encapsulating assembly, engageable within the watertight chamber (13) disposed at the bottom of the rear gallery contained in the body (R) such that. the front end of the plunger (12) rests against the rear face of the hole (9) while the annular shoulder of the coil (11) fits into a recess (15) formed from the plastic deformation of the perimeter of the gallery opening posterior body (R).
- the gas, pressurized in the manifold (TD), is introduced into the register through the inlet port that will lead it to the watertight chamber. (13) of the flame monitoring device (DSC).
- FIG. 6 which are: front subassembly formed by spring-loaded shutter, plunger (12) and one bearing fixed to the registration body and the other rear sub-assembly formed by coil (11), wires and contact fixing housing. At the end of the subset manufacturing process, they are mounted directly inside the body
- the selector head is designed in such a way that its inner face has gear "teeth" with a profile similar to that used with Philips type screwdrivers. Perpendicular to the selector shaft is a hole (19) that exposes the teeth of the secondary selector head (17) (Fig. 7), with half of this hole opposite the teeth having a taper similar to that found on standard Philips-type tips. In this way, the selector can be turned by a Philips screwdriver from the front of the stove by removing only the handle of the register, without the need to disassemble the entire upper part of the stove.
- the minimum flow rate is achieved by aligning the selector passageway (8) with one. communication hole (18) with a chamber produced transversely to the longitudinal axis of the register, containing within it a secondary selector (17) that regulates the gas passage (Fig. 3).
- Another differential is the fixing of subsets by plastic deformation of the registration body without the need for. nuts, sealing and preventing access to the inside of the product (Fig. 2).
- the present descriptive report deals with a conception of gas registration with a flame monitoring device, presenting, as evidenced by the analysis performed and the figures shown, numerous differences on the conventional registrations existing in the consumer market, besides constructive and functional technical characteristics completely different from those pertinent to the state of the art.
