Abstract
A burner tempering prevention security device. The utility model comprises a controller, a valve body, a spraying nozzle, an injector, and a burner head part, the utility model is mainly characterized in that the utility model also comprises an inductor for detecting signals arranged in the injector, and the controller receives the signal transferred by the inductor and drives the valve body to actuate to cut off the gas source. The utility model has the advantages that the gas source which can produce the tempering phenomenon of the burner can be effectively cut off, to avoid the burner to be burnt.
Description
Technical field: the utility model relates to a kind of combustion gas tool burner anti-backfire safety device.
Background technology: the burner of existing gas heater, imflammable gas burns under the support of its structure, when the burning velocity of imflammable gas greater than by the flowing velocity of the imflammable gas nozzle injection, that mixed with air the time, just can produce the combustion conditions of tempering.Specifically to be exactly flame pass in injector from the fire hole of burner head for it, i.e. burner cavity makes imflammable gas just burning before nozzle.When producing this tempering phenomenon, burner is red because of contacting with the flame of high temperature by burning, deliquescing subsequently, distortion are up to being burnt, even blast etc. causes direct economic loss to the mankind harm appears, in the time of flame contact huyashi-chuuka (cold chinese-style noodles) also a large amount of black smokes can appear, not only pollute, and have hidden danger such as CO poisoning, jeopardize user's life to atmosphere.In order to overcome these defectives, burner anti-backfire safety device is developed.
Summary of the invention: technical problem to be solved in the utility model provides a kind of burner anti-backfire safety device, and it can cut off the source of the gas that burner produces tempering phenomenon effectively, avoids burning out burner.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises controller, valve body, nozzle, injector, burner head, it also is included in the inductor that is provided with detection signal in the injector, described controller is by receiving the signal that inductor transmits, and the driver's valve body action cuts off source of the gas.
Described inductor is thermocouple, temperature sensor, flame sensor, fuse.
The edge of described inductor and the central axis of nozzle are tangent.
The utility model is compared the beneficial effect that is produced with prior art:
1, because adopting, the utility model in injector, is provided with inductor, when burner produces tempering phenomenon, being flame passes in injector from the fire hole of burner head, at this moment, the inductor that is located in the injector runs into high temperature or touches flame, and the generation effect, give controller by the transmission signal, controller orders about valve body gas circuit is cut off, combustion gas is closed, thereby avoiding flame is the injector internal-combustion at burner cavity, and the assurance burner is not burnt red because of tempering or burns, even avoids producing the harm that jeopardizes user's security of the lives and property.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: referring to accompanying drawing 1, inductor 4 is located in the injector 5, and described inductor is the sensitive object of thermoelectric induction, can be structures such as thermocouple, temperature sensor, flame sensor, fuse, is placed on diverse location or different angles.
When combustible gas gas flows into from valve body 2, by nozzle 3 with enter in the injector 5 after air tentatively mixes, under effect, flow through burner head 6 and lighted at extraneous blast pressure, carry out normal combustion simultaneously.Because of some extraneous reason,, just can produce the phenomenon of tempering when the burning velocity of imflammable gas during greater than its flowing velocity.This moment, flame imported into from burner head 6, will spread all in the injector 5 and all light to the imflammable gas between the nozzle 3.This moment; inductor 4 runs into high temperature or touches flame and the generation effect; it produces signal rapidly and is transferred to controller 1, under the effect of controller 1, orders about valve body 2 actions; imflammable gas is dammed at valve body 2 places; promptly cut off source of the gas effectively, thereby stoped the generation of tempering phenomenon, protected burner not red because of contacting with the flame of high temperature by burning; deliquescing then, distortion be up to being burnt, even blast etc. causes direct economic loss to the user harm occurs.
