Description

The safety gas cock that is used for dual burner
Technical field
The present invention relates to be used for the safety gas cock of dual burner.
Background technology
Dual burner is known.This dual burner is concentric burner, has circumferential body or outer burner that its central body that is provided with interior flame rings on every side or inner burner and its periphery are provided with one or two concentric flame rings.
Mention a kind of burner in this manual, its outer annular body is provided with two flame rings, also is effective but be provided with under the situation of single flame rings in the outer body of burner.
In known dual burner, first nozzle is related with central body so that coal gas is provided for first Venturi tube, the coal gas-air mixture forms therein so that offer interior flame rings, and second nozzle is related with circumferential body so that coal gas is provided for second Venturi tube, and the coal gas-air mixture forms and offer outer flame rings therein.
Two Venturi tubes are by two of single cock different outlet air feed, and the user controls different operation of combustors patterns as requested thus.These operator schemes are such: promptly, no matter the outer body of burner still is that inside subject can both obtain supplying with, so that produce by the adjustable flame rings of minimum to maximum; Perhaps have only inside subject to obtain supplying with, so that produce by minimum to maximum adjustable interior flame rings.In any one operator scheme, interior flame rings always obtains supplying with, and therefore near the burner inside subject safety device thermocouple has been installed.
In these known burners, always select different operator schemes and pass through single knob adjusting, when knob, the adjustment cone of the two outlet taps of knob control.
Be used for the first kind cock of dual burner, when knob was in 0 ° of position, burner cut out, and was in 90 ° position when knob, and two burner bodies (outside with inside) all obtain the supply of maximum stream flow; Then, from 90 ° to about 140 ° process, the flow by two burner bodies reduces gradually, up to reaching minimum of a value; Then, from 140 ° to 180 °, the supply of outer body is interrupted, and is increased to its maximum by the flow of inside subject; Finally, after passing through 180 ° position, only the gas flow by inside subject reduces up to its minimum of a value, and promptly knob is in stop position.
Be used for the second type cock of dual burner, when knob was in 0 ° of position, burner cut out, and was in 90 ° position and work as knob, had only the internal-combustion apparatus main body to obtain the supply of maximum stream flow; Then, from 90 ° to about 140 °, its flow is reduced up to reaching minimum of a value; Then, from 140 ° to 180 °, two burner bodies all obtain supplying with, and are in maximum stream flow at 180 °; Finally, the gas flow by two burner bodies reduces up to minimum of a value, and promptly knob is in stop position.
Obviously, the dual burner cocks of two known types is difficult to be regulated by the user, because regulate directly not directly perceived.
Except this defective, the dual burner cocks of two known types shows another more important drawback, because the process of the knob position of only giving the inner burner air feed from correspondence to the knob position of two burner air feed to correspondence, the position that the coal gas that does not have accurately qualification to supply with outer burner is interrupted really.Therefore, if be used for not closing fully to the outlet of outer burner supply coal gas, because interior ring obtains supplying with and thermocouple is activated, this situation may not can be detected by safety device.In this case, the amount of coal gas-air mixture of outer body is too little can not to cause internal combustion by the flame of inner burner between two burners to such an extent as to leave, and therefore unburned gas leakage is in air.
WO2005/003610 has explained this problem and by preventing that the user from can move to knob this critical localisation and solve this problem.Especially, this document suggestion can be arranged on the cock control lever that the synergistic spring of ridge on the tap body is applied to knob.When cock operating period spring touched this ridge, the user had to bigger strength knob be crossed the critical zone.
But, because the user think this strength be cock incomplete operation and because not do not eliminate since its operation of shortage experience the problem that causes directly, intuitively, this scheme can not be satisfactory.
Summary of the invention
The objective of the invention is to eliminate these defectives by the relief cock that is provided for dual burner, wherein when burner had only the flame of centre ring to operate with minimum of a value, unburned coal gas can not leak from outer annular body.
Another object of the present invention provides a kind of cock, wherein the user to regulate operation be simply and intuitively, can not cause the sensation of faulty operation.
The purpose of these and other becomes obviously according to description subsequently, and according to the present invention, is achieved by the gas safety cock that is used for dual burner, according to claim 1.

Fig. 4 a-4c is the schematic front view of three diverse locations of control cock that only is used for giving the central body air feed of burner, and this plane illustrates the state of corresponding flame rings.
The specific embodiment
As shown in the figure, relief cock of the present invention is used for to traditional dual burner air feed, promptly burner comprise central body 2 or inner burner and with the former concentric circumferential body 4 or outer burner.
Inner burner 2 is provided with a flame rings 6, and outer burner 4 is provided with from its periphery and week forms in it two flame rings 8,8 ', although only can provide in different burner types from the independent flame rings of the periphery formation of outer burner 4.
The two obtains inner burner 2 and outer burner 4 supplying with by cock of the present invention, and this cock comprises having: be used to connect distribution header gas entry 10 main body 9 and be used for independently two gas exits 12 and 14 to two burners 2 and 4 air feed.
Inlet 10 is connected with chamber 18 by pipeline 16, closes by related with electromagnet 22 in a conventional manner valve element 20.This closed condition keeps by spring 24, opens described chamber 18 but spring 24 can be withdrawn therefrom, and it is connected with the chamber 26 in downstream.With with the identical mode of most cocks that has thermocouple safety device, the electric current electromagnet 22 that produces by thermocouple 28 is activated so that the reaction force holding chamber 18 of antagonistic spring 24 is opened, and thermocouple 28 is arranged near the of inner burner 2 and flame 6 sensitivities to producing from the latter.
The chamber 26 in downstream communicates with the inner chamber of adjustment cone 29, and adjustment cone 29 is fixing with bar 30, and adjusting knob 32 is applied to bar 30.
Situation with the traditional relief cock that is used for burner is the same, bar 32 and cone 29 also are movable vertically, so that manually control the interim motion of electromagnet 22, cause chamber 18 to be opened, produce maintenance electromagnet 22 up to thermocouple 28 and be in the necessary electric current of open mode.
The sidewall of adjustment cone 29 also comprises pair of holes 34 and 36, and when the change in angular position of cone, cone forms between chamber and hole 38 and 40 within it in a conventional manner and is communicated with, and hole 38 and 40 is arranged in the cone seat and is connected to two gas exits 12 and 14.
According to the design data of burner, hole 34,36,38 and 40 angular breadth is set to enough make the flow of coal gas to be adjusted, and still, this belongs to part well known by persons skilled in the art and does not need and further specifies.
In addition, two outlets 12 and 14 are provided with traditional branch road 42,44, and according to the angle position of the angle position of knob 32 and the cone 29 of fixing with it, branch road 42,44 has guaranteed that coal gas offers two burners 2 and 4 with the flow of minimum.
Relief cock of the present invention is operated in the following manner:
