[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, a kind of two outlet gas valves with Flow-rate adjustment, include valve body 1, on valve body 1, be provided with gas-entered passageway 2 and the first outlet passageway 3, the second outlet passageway 4, gas-entered passageway 2 is arranged at valve body 1 bottom, the adjustable variation of flow in the first outlet passageway 3, constant flow in the second outlet passageway 4 is constant, in valve body 1, be provided with gas-entered passageway 2 and the first outlet passageway 3, the valve pocket 5 that the second outlet passageway 4 is communicated with, in the interior rear channels of valve pocket 5, be provided with solenoid valve 6, solenoid valve 6 is controlled the circulation of whole gas valve, after closing, the first outlet passageway 3, the second outlet passageway 4 is is all come in and gone out without fluid.In the interior front channels of valve pocket 5, be provided with spool 7, on spool 7, be provided with a plurality of port holes that are arranged in order 71, described port hole 71 is not for being conducting to the blind hole of valve core inside, between adjacent port hole 71, be respectively equipped with the metering orifice 72 being interconnected, each metering orifice being arranged in order 72 changes from small to big by ashamed, maximum metering orifice 721 is communicated with the first outlet passageway 3 by first-class circulation passage 73, between described center hole 8 and the first outlet passageway 3, be also provided with the adjusting passage that regulates throughput, on described adjusting passage, be also provided with controlling device, described the second outlet passageway 4 is connected to the front channels of valve pocket 5 by the second circulation passage 74 on spool 7, the afterbody of described spool 7 is provided with the slewing gear of energy rotational valve core 7.
Slewing gear can make the first outlet passageway 3 or the second outlet passageway 4 be communicated with or cut out with gas-entered passageway 2.Described the first outlet passageway 3 is for cooking food, the second outlet passageway 4 is incubated for food, and the first outlet passageway 3, the second outlet passageway 4 can not be worked simultaneously, rotational valve core 7 makes the first outlet passageway 3 be communicated with gas-entered passageway 2, burner starts cooking food, after having toasted, is threaded to insulation shelves, the second outlet passageway 4 is communicated with gas-entered passageway 2, food is incubated.Port holes 71 different on spool 7 have represented different gears, and the gas output of each gear is different, and different gas outputs is corresponding different combustion temperature again, therefore this pair of outlet passageway gas valve can be used for toasting different food.
Spool 7 is cone-shaped, the part that valve pocket 5 matches with spool 7 is also all cone-shaped, in spool 7 axis centre, be provided with a center hole 8, center hole 8 is communicated with the first outlet passageway 3, the second outlet passageway 4, and described first-class circulation passage 73, second circulation passage 74 are for being located at the through hole being connected with center hole 8 on spool 7.
According to actual needs, the gear of a plurality of cooking foods can be set, in the present embodiment, port hole 71 is four, described first-class circulation passage 73 comprises two through holes, be respectively small through hole 81, large through-hole 82, the metering orifice 72 in described connection adjacency channel hole 71 is arranged in order and change from small to big in aperture, and the metering orifice of aperture maximum is communicated with described small through hole 731, described small through hole 731 and the mutual conducting of large through-hole 732, the aperture of described small through hole 731 is less than the aperture of large through-hole 732.A plurality of described port holes 71 also can be with through hole and the aperture of center hole 8 conductings and change from small to big in addition, thereby remove metering orifice.Clockwise, first port hole connection corresponds to first grade, the rest may be inferred, therefore this pair of outlet passageway gas valve main airway comprises six gears, owing to changing from small to big in metering orifice 72 apertures, the aperture of small through hole 731 is less than the aperture of large through-hole 732, therefore next gear is all large than a upper gear gas output, combustion temperature also raises gradually, slewing gear rotational valve core 7, make one of them port hole 71 or large and small through hole on spool 7 be communicated with the first outlet passageway 3, fluid enters center hole 8 through solenoid valve 6, finally from the first outlet passageway 3, flows out.The setting of six gears of the utility model, compares two or three gears, makes in specific temperature range, and adjustable temperature is thinner, avoids selecting gear less than normal to cause food to be difficult to boil user, or selects gear bigger than normal to cause energy waste.
As Figure 10, from OFF-POS.6, the interior flow of the first outlet passageway 3 increases gradually, and firepower progressively strengthens, and the main fiery air outlet of POS.6 firepower is maximum, and side outlet is without fire; POS-1 the second outlet passage is communicated with, and primary outlet is without fire.
Described adjusting passage includes a plurality of supplementary airway passage hole 75 and the supplementary air flue through hole 76 that is arranged on annular arrangement on spool 7, and of the present utility model supplementary airway passage hole 75 is 5, and supplementing air flue through hole 76 is 1.Between adjacent supplementary airway passage hole 75 and adjacent supplementary airway passage hole 75 and supplementary air flue through hole 76, be provided with the supplementary upper airway flow metering-orifice 77 being interconnected, the aperture of described supplementary upper airway flow metering-orifice 77 is consistent, supplement air flue through hole 76 and be communicated with the first outlet passageway 3 and center hole 8, can allow fluid enter into the first outlet passageway 3 from gas-entered passageway 2, be provided with main airway passage 11 and the supplementary airway passage 12 corresponding with first-class circulation passage 73 and supplementary air flue through hole 76 valve body 1 is corresponding, described the first outlet passageway 3 is connected to gas-entered passageway 2 by main airway passage 11 and supplementary airway passage 12.
Described supplementary air flue and main airway are worked simultaneously, and when rotational valve core 7 makes first port hole 71 on spool 7 be communicated with main airway passage 11, first supplementary airway passage hole 75 that spool 7 rear sides are corresponding is also communicated with supplementary airway passage 12.
Described controlling device includes the adjustment hole 13 of that be provided with and supplementary airway passage 12 conductings of valve body 1, in described adjustment hole 13, be provided with the micrometer adjusting screw 9 being connected with valve body 1 inner thread, described micrometer adjusting screw 9 forms an energy with adjustment hole 13 inwalls and the gas that enters adjustment hole 13 is delivered to the adjustable clearance of the first outlet passageway 3, and the size of described adjustable clearance can regulate by rotating micrometer adjusting screw 9.Because adding man-hour size, main airway passage 11 can there is deviation, make the gas output of the first outlet passageway 3 not reach design load, therefore be provided with supplementary airway passage 12 at the rear side of main airway, main airway is done slightly littlely, by supplementing air flue, regulate, can guarantee that total gas output reaches design load.Described micrometer adjusting screw 9 is provided with the O shape circle 14 that prevents spool 7 interior gas leaks.
Described each port hole 71 and supplementary airway passage hole 75 are arranged on the conical surface of spool 7, and corresponding with metering orifice 72 and supplementary upper airway flow metering-orifice 77.
