Referring to figs. 1 to Fig. 3, symbol 1 is an example of gas cock of the invention.The gas cock 1 is by coal gas from inflow
Mouth imports, and the coal gas imported is branched to two systems, come the component for flowing out coal gas from two outfluxes 12,13.Symbol
Numbers 8 be concentric burners, and the concentric burners 8 are so as to be fed separately to main burning from the coal gas that two outfluxes 12,13 flow out
The mode of device 81 and auxiliary burner 82 configures.
To concentric burners 8 the fire extinguishing state flowed out since two outfluxes 12,13 without coal gas, i.e. full off state
When being lighted a fire, operating shaft 2 is pressed into downward, rotates operating shaft 2 towards left while keeping this indentation state.
The upper and lower plates 3 moved up and down together with operating shaft 2 are installed in operating shaft 2, by the way that operating shaft 2 is depressed, on
Lower plate 3 moves to open microswitch 72 downward.In this way, controller (not shown) detects that operating shaft 2 is depressed, and make
Same spark plug movement (not shown), and interrupted spark discharge is generated near concentric burners 8.
In operating shaft 2, is similarly moved up and down together with operating shaft 2 and the cam 5 rotated together with operating shaft 2 is arranged
In the top of upper and lower plates 3.If rotating operating shaft 2 in the state of being pressed into operating shaft 2, cam 5 makes microswitch 71
It opens, above controller can detect that operating shaft 2 rotates.In addition, being equipped with plug (not shown) in the lower end of operating shaft 2
Son, if rotating operating shaft 2, plug is also rotated together, and the flow of the coal gas flowed out from outflux 12,13 gradually increases, until
Before few aperture in plug reaches standard-sized sheet, reliably light a fire to concentric burners 8.
In addition, it is built-in with electromagnetic valve at the position shown in symbol 14, when above-mentioned upper and lower plates 3 move downward,
Above-mentioned microswitch 72 is opened, and the protrusion 17a of oscillating deck 17 is depressed.Above-mentioned oscillating deck 17 is kept into is with swinging axle 16
Center freely swings, if pressure protrusion 17a, oscillating deck 17 swing towards the rear, bar 15 pushed towards the rear.
If above-mentioned bar 15 is pushed towards the rear, the spool of above-mentioned electromagnetic valve is crimped into electromagnet, in this state
After lower completion is to the igniting of concentric burners 8, electric current is kept to electromagnetism iron supply, to adsorb spool.Thus, even if because having lighted a fire
Hand is unclamped into operating shaft 2 after and resets operating shaft 2 upward, be pressed into oscillating deck 17 no longer towards the rear bar 15, electricity
Abampere full valve can also continue to keep valve opening state.
Referring to Fig. 4, the outer peripheral surface of cam 5 becomes the cam surface 51 for opening above-mentioned microswitch 71.Above-mentioned cam 5
To be hollow, two recess portions 52,53 and a protrusion 54 are formed in inner peripheral surface.
On the other hand, as shown in figure 5, a pair of protrusion 31 for cutting shape is formed on upper and lower plates 3, as elastomeric element
, be wound into circular spring 4 and engage with protrusion 31.The both ends inwards warpage of the wire rod of spring 4 is constituted, and forms pawl 41.
Above-mentioned pawl 41 is configured to engage with above-mentioned protrusion 31 and rotate spring 4 relative to upper and lower plates 3.Alternatively, it is also possible to by two
The warpage, and the providing holes on upper and lower plates 3 in advance downward of pawl 41, rather than protrusion 31, and by inserting the pawl of warpage downward
Enter above-mentioned hole, to realize rotation stop.
In addition, forming holding section 42 in a manner of stretching out towards outside, engage with above-mentioned recess portion 52,53, but will be above-mentioned
In the case that recess portion 52,53 and protrusion 54 are formed in the top plate face of cam 5, the flexagon in a manner of erecting upward of holding section 42
At.
On the other hand, upper and lower plates 3 are moved up and down with operating shaft 2 together as described above, but must be incited somebody to action when moving downward
Microswitch 72 is opened, and protrusion 17a is depressed.However, due to making depressing force act on the work of microswitch 72 and protrusion 17a
With point 34 far from operating shaft 2, therefore, if being loosened in installation of the upper and lower plates 3 relative to operating shaft 2, due to upper and lower plates 3
Run-off the straight, and make a concession position 34 upward, accordingly, there exist can not sufficiently be pressed into towards the rear bar 15, in addition can not incite somebody to action
Microswitch 72 opens such unfavorable condition.Therefore, using following scheme: forming slot 22, the width of the slot 22 in operating shaft 2
Degree is dimensioned so as to can be substantially seamlessly mutually embedding for upper and lower plates 3, and operating shaft 2 can rotate in the state of mutually embedding, another
Aspect, communicatively being formed on upper and lower plates 3 can be for big hole portion 32 and diameter that the axle portion 21 of operating shaft 2 is passed through close to 22 bottom of slot
Diameter small hole portion 33, by by operating shaft 2 pass through big hole portion 32, then, by small 33 embedded groove 22 of hole portion, by upper and lower plates
3 are not installed on operating shaft 2 loosely.In addition, bracket 6 limits the horizontal direction of upper and lower plates 3 after assembling gas cock 1
Movement, therefore, slot 22 will not be mobile towards big 32 side of hole portion.
Referring to Fig. 6, as described above from fire extinguishing state, i.e. full off state is lighted a fire in the case where, initially by operating shaft 2
It is pressed into (a) downward.Then, in the state of above-mentioned indentation, operating shaft 2 is made to rotate (b) towards left.Rotate operating shaft 2
When to strong fiery position (fully open position), click effect is generated since the holding section 42 of spring 4 is mutually embedding with recess portion 52, and be used to rotate
The torque of operating shaft 2 increases, and therefore, operator is able to know that the position is in fully open position.It keeps pressing operating shaft 2 such
After the time of the state entered to a certain degree, the igniting of concentric burners 8 is completed, the spool of electromagnetic valve is made to be adsorbed in electromagnetism
Iron.If in this state unclamping hand, operating shaft 2 returns upward under the action of the active force of spring (not shown).If
Operating shaft 2 is being rotated from the full-gear to (c) full off state, then the firepower of concentric burners 8 can made to increase or decrease.
Then, want so that auxiliary burner 82 is in combustion state in the case where, cross fully open position make operating shaft 2 into
One step is rotated towards left.In the range shown in symbol d, two burners 81,82 is kept to be in strong fiery state, and makes firepower
Do not change, but by keeping holding section 42 and next recess portion 53 mutually embedding, temporarily cease operating shaft 2.If making operating shaft 2 into one
Step is rotated towards left, then can only reduce the firepower (e) of main burner 81, but in the range of above-mentioned symbol e, main burner 81 can
Tempering phenomenon (Japanese: back-fire phenomenon) can be generated, and it is therefore not desirable to stop operating shaft 2 in the range of e.Therefore, it is arranged
There is protrusion 54.
The holding section 42 of spring 4 is mutually embedding with recess portion 53 when being moved to symbol e from symbol d, but in order to further towards left
Rotation, holding section 42 must pass over protrusion 54.Thus, in order to continue to rotate operating shaft 2, and need biggish torque.If not yet
Protrusion 54 is crossed, operating shaft 2 can be refunded towards right, but once cross protrusion 54, then torque sharply becomes smaller, and therefore, can make to grasp
Make the range that axis 2 turns to symbol f quickly.
When entering the range of symbol f, main burner 81 is put out a fire, and auxiliary burner 82 is burnt with strong fiery state.If in symbol f
In the range of further towards left rotate, then the firepower of auxiliary burner 82 can be decreased to minimum firepower.Make from above-mentioned state
When concentric burners 8 are put out a fire, as long as operating shaft 2 is turned to fire extinguishing position towards right.Protrusion is crossed again on the way at it
54, then by successively mutually embedding with recess portion 53,52, and generate click effect.
In addition, can also be carried out without departing from the scope of the subject in the invention the invention is not limited to above embodiment
Various changes.
