Fig. 7 (a) provides the control valve cutaway view in another preferred embodiment of the present invention, and Fig. 7 (b) i.e. is the expansion schematic diagram of this regulation valve core anchor ring.The difference of this control valve and structure shown in Figure 5 is, regulation valve core 72 is provided with spools emanate a mouthful 74a, 74b and the 74c of three 120 degree positions that are separated by, these three spools mouthful opening degree different sizes of emanating, corresponding respectively three kinds of situations using natural gas (T), liquefied gas (Y) and artificial coal gas (R).Consider equally when regulation valve core 72 relative adjustment valve bases 71 rotate, the progressive increase of firepower of main combustion fire or reduce, three spools mouth of emanating roughly is sector structure on the anchor ring of regulation valve core 72.
Below in conjunction with accompanying drawing operation principle of the present invention is described.
From above-mentioned each several part STRUCTURE DECOMPOSITION description of drawings, can recognize that combustion gas at first enters whole kitchen range by switch valve 22, when switch valve was in closed condition as accompanying drawing 6, whole gas kitchen ranges was in closed condition.This moment, control valve was in the adjusting original position as shown in Figure 5.The relation of three meshing gears also as shown in Figure 4.
When partial gear among Fig. 4 43 is spent with 31 reverses 0～90 of Range switch knob, be meshing with each other with switch valve gear 45 all the time, and partial gear 43 continues to reverse 90～180 degree ability and control valve gear 41 meshes.
When opening kitchen range, concrete operations are Range switch knob 31 contrary the turning 90 degrees that will be arranged on partial gear 43 coaxial core 44, partial gear 43 contrary turning 90 degrees, owing to this moment partial gear 43 and switch valve gear 45 intermeshing relations, drive switch valve gear 45 like this and clockwise rotate 90 degree, among Fig. 6 as can be seen, switch valve spool 46 turns over 90 when spending clockwise, its spool air inlet 64 is aimed at fully with valve seat air inlet 63, the gas circuit of switch valve is opened, partial gear 43 is not to the position that can be meshed with control valve gear 41 (i.e. 90～180 degree) at this moment, and control valve gear 41 still is failure to actuate.As shown in Figure 5 on the control valve of state, its regulation valve core is emanated and mouthfuls 54 is in breakthrough status with valve seat gas outlet 55, and spool is emanated and mouthfuls 54 is in the unlatching maximum position.
When Range switch knob 31 continues to rotate in counterclockwise 90～180 scopes, this moment, partial gear 43 and control valve gear 41 were in the state of being meshed, control valve gear 41 clockwise rotates corresponding angle with the reverse of partial gear 43 like this, as shown in Figure 5, mouthfuls 54 rotational angles with 90～180 degree of emanating on the regulation valve core 42 increase and reduce combustion gas gradually by the emanate bore of mouthful 54 directive valve seat gas outlets 55 of its spool, reach the purpose of regulating size.And the emanate angular dimension relation of being inversely proportional to of mouthfuls 54 size variation and switching knob 31 adjustings of this spool.Mouth 54 structurally has fan-shaped feature owing to emanate, and the adjusting of the intensity of a fire of gas kitchen ranges can be gradually greatly gradually little like this, conveniently freely.
On the contrary, in the time will closing kitchen range, switching knob returns clockwise and turn 90 degrees in the scope, and at first the control valve gear 41 of drive and partial gear 43 engagements returns to the position shown in Fig. 5 (a); When the clockwise revolution 90～180 of switching knob continuation was spent, partial gear 43 broke away from the engagement of control valve gear 41, and in this process, the control valve maintenance is motionless, and switch valve gear 45 drive switch valves return to state as shown in Figure 4 up to cutting out source of the gas.And switch valve also recovers state as shown in Figure 6.Using method of the present invention is consistent with the using method of general gas kitchen range.
Certainly, suitably increase the number of teeth of partial gear 43, the spool of control valve is emanated mouthfuls 54 when kitchen range are in the combustion gas closed condition, also be in closed condition, when Range switch knob 31 contrary turning 90 degrees, be in the maximum mouthful position of emanating again.
In addition, make control valve emanate mouthfuls 54 opening length when increasing or shortening at needs, as long as the size between appropriate change control valve gear 41 and the partial gear 43 just can be accomplished.Lifting three gear sizes in the embodiments of the invention is 1: 1: 1.
The embodiment that Fig. 7 provides is applicable to the control valve structure under the multiple source of the gas type.In use, when the combustion gas type changes, only need clockwise or rotate counterclockwise 120 degree, choose emanating of should source of the gas using mouthful get final product, also ever-burning flame need be adjusted simultaneously certainly control valve.So just can make gas kitchen ranges be applicable to three kinds of sources of the gas fully.According to same principle, can also use more sources of the gas.
The front provides the description to preferred embodiment, so that any technical staff in this area can use or utilize the present invention.Various modifications to these embodiment are conspicuous to those skilled in the art, can be applied to other embodiment to total principle described here and not use creativeness.Thereby, the embodiment shown in the present invention will be not limited to here, and the wide region of principle that should disclose and new feature according to meeting here.
