[embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of gas valve with Flow-rate adjustment, include valve body 1, be provided with gas-entered passageway 2 and outlet passageway 3 on valve body 1, gas-entered passageway 2 is arranged at valve body 1 bottom, the adjustable variation of flow in outlet passageway 3, in valve body 1, be provided with gas-entered passageway 2 and outlet passageway 3, the valve pocket 4 that is communicated with, be provided with solenoid valve 5 in the interior rear channels of valve pocket 4, solenoid valve 5 is controlled the circulation of whole gas valve, after closing, outlet passageway 3 is come in and gone out without fluid.Be provided with spool 6 in the interior front channels of valve pocket 4, on spool 6, be provided with the connecting passage that can allow fluid enter into outlet passageway 3 from gas-entered passageway 2, this connecting passage includes and is located on spool 6 multiple counterbores 61 of circumferential array successively, described counterbore 61 is not for being conducting to the blind hole of valve core inside, the corresponding metering orifice 62 being interconnected that is provided with between adjacent counterbore 61, the metering orifice 62 that each is arranged in order changes from small to big gradually, maximum metering orifice 62 is communicated with outlet passageway 3 by circulation passage 63, and the afterbody of described spool 6 is provided with the slewing gear of energy rotational valve core 6.Slewing gear can make outlet passageway 3 be communicated with or cut out with gas-entered passageway 2.Described outlet passageway 3 is for cooking food, rotational valve core 6 makes outlet passageway 3 be communicated with gas-entered passageway 2, burner starts cooking food, counterbores 61 different on spool 6 have represented different gears, the gas output of each gear is different, different gas outputs is corresponding different combustion temperature again, therefore this gas valve can be used for toasting different food.
Spool 6 is cone-shaped, the part that valve pocket 4 matches with spool 6 is also all cone-shaped, be provided with a center hole 7 in spool 6 axis centre, center hole 7 is communicated with outlet passageway 3, and described circulation passage 63, second circulation passage 64 are for being located at the through hole being connected with center hole 7 on spool 6.
According to actual needs, the gear of multiple cooking foods can be set, in the present embodiment, counterbore 61 is four, described circulation passage 63 comprises two through holes, be respectively small through hole 81, large through-hole 82, the metering orifice 62 of the adjacent counterbore 61 of described connection 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 631, described small through hole 631 and the mutual conducting of large through-hole 632, the aperture of described small through hole 631 is less than the aperture of large through-hole 632.Multiple described counterbores 61 also can be with through hole and the aperture of center hole 7 conductings and change from small to big in addition, thereby remove metering orifice.Clockwise, first counterbore 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 62 apertures, the aperture of small through hole 631 is less than the aperture of large through-hole 632, therefore next gear is all large than a upper gear gas output, combustion temperature also raises gradually, slewing gear rotational valve core 6, make one of them counterbore 61 or large and small through hole on spool 6 be communicated with outlet passageway 3, fluid enters center hole 7 through solenoid valve 5, finally flows out from outlet passageway 3.The setting of six gears of the present invention, 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 Fig. 8, the flow in OFF-POS.6 outlet passageway 2 increases gradually, and firepower progressively strengthens, the main fiery air outlet of POS.6 firepower maximum.
Described connecting passage also includes the multiple supplementary air flue counterbore 65 and the supplementary air flue through hole 66 that are arranged on annular arrangement on spool 6, and of the present invention supplementary air flue counterbore 65 is 5, and supplementing air flue through hole 66 is 1.Between adjacent supplementary air flue counterbore 65 and adjacent supplementary air flue counterbore 65 and supplementary air flue through hole 66, be provided with the supplementary upper airway flow metering-orifice 66 being interconnected, the aperture of described supplementary upper airway flow metering-orifice 66 is consistent, supplement air flue through hole 66 and be communicated with outlet passageway 3 and center hole 8, can allow fluid enter into outlet passageway 3 from gas-entered passageway 2, be provided with main airway passage 11 and the supplementary airway passage 12 corresponding with circulation passage 63 and supplementary air flue through hole 66 valve body 1 is corresponding, described 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 6 makes first counterbore 61 on spool 6 be communicated with main airway passage 11, first supplementary air flue counterbore 65 that spool 6 rear sides are corresponding is also communicated with supplementary airway passage 12.On valve body 1, be also provided with the adjustment hole 13 with supplementary airway passage 12 conductings, in described adjustment hole 13, be provided with the micrometer adjusting screw 8 being connected with valve body 1 inner thread, energy of described micrometer adjusting screw 8 and adjustment hole 13 inwalls formation is delivered to the gas that enters adjustment hole 13 adjustable clearance of outlet passageway 3, and the size of described adjustable clearance can regulate by rotating micrometer adjusting screw 8.Because adding man-hour size, main airway passage 11 can there is deviation, make the gas output of outlet passageway 3 not reach design load, therefore be provided with and supplement airway passage 12 at the rear side of main airway, main airway does slightly littlely, regulate by supplementing air flue, can guarantee that total gas output reaches design load.Described micrometer adjusting screw 8 is provided with the O shape circle 14 that prevents spool 6 interior gas leaks.
Described each counterbore 61 and supplementary air flue counterbore 65 are arranged on the conical surface of spool 6, and corresponding with metering orifice 62 and supplementary upper airway flow metering-orifice 66.
Described slewing gear is rotating shaft 9, rotatable spool 6, and described valve body 1 afterbody is provided with the valve seat 15 of fixed rotating shaft 9.Described valve seat 15 is connected with described valve body 1 rear end screw.Described spool 6 is taper, is provided with the spool spring 16 that spool 6 tops is pressed in to valve body 1 inwall between valve seat 15 and spool 6 afterbodys.The end that valve seat 15 is stretched in described rotating shaft 9 is provided with fixture block 91, is also provided with draw-in groove 68 in the end of spool 6, and described fixture block 91 snaps in draw-in groove 68, rotates for stirring rotary spool 6.
