[embodiment]
Below in conjunction with accompanying drawing, the invention will be further described:
A kind of gas valve, include valve body 1, on valve body 1, be provided with suction port 2 and outlet passageway 4, in described valve body 1, be provided with the valve pocket 17 that suction port 2 and outlet passageway 4 are communicated with, in valve pocket 17, be provided with rotary spool 5, described rotary spool 5 inside, one end are provided with the center hole 20 with outlet passageway 4 conductings, the other end inside is provided with the receiving bore 24 with center hole 20 conductings, described rotary spool 5 is provided with and can allows gas enter into center hole 20 from suction port 2, the main airway that gas output is adjustable, described main airway comprises multiple first inlet holes 6 that can be communicated with suction port 2 and center hole 20 that are located on rotary spool 5 walls and are arranged in order, in rotary spool 5 walls of described main airway rear side, be also provided with the supplementary air flue that can be communicated with suction port 2 and receiving bore 24 in the time that main airway is communicated with suction port 2 and center hole 20, in described receiving bore 24, be also provided with the micrometer adjusting screw 10 being connected with rotary spool 5 inner threads, energy of described micrometer adjusting screw 10 and rotary spool 5 inwalls formation is delivered to the gas that enters receiving bore 24 adjustable clearance 21 of center hole 20, the large I of described adjustable clearance 21 regulates by turning micrometer adjusting screw 10, described rotary spool 5 afterbodys are provided with the slewing gear that can rotate rotary spool 5.Slewing gear can make main airway, supplementary air flue be communicated with or cut out with suction port 2.Each first inlet hole 6 of described main airway represents a gear, and the gas output of each gear is different, and different gas outputs can produce again different combustion temperature, thereby can toast different food.Because the first inlet hole 6 of main airway adds man-hour can there is deviation in size, makes the gas output of outlet passageway 4 not reach design load, thus be provided with supplementary air flue at the rear side of main airway, to guarantee that total gas output reaches design load.
On described valve body 1, be respectively equipped with and be communicated with the first gas-entered passageway 3 of main airway and suction port 2, the second gas-entered passageway 8 that connection supplements air flue and suction port 2.
For realizing the difference of main airway gas output, the first inlet hole 6 on rotary spool 5 can be made to various structures, as the first inlet hole 6 all made and the through hole of center hole 20 conductings, and the aperture of through hole changes from small to big, and so just can realize the ascending adjusting of gas output.Also the combination that multiple described the first inlet holes 6 can be made to blind hole and through hole, comprise the through hole of at least two blind holes and at least one and center hole 20 conductings, between adjacent blind hole and between adjacent blind hole and through hole, be provided with the first-class metering-orifice 18 being interconnected, described first-class metering-orifice 18 pore sizes are unequal.
Further, described blind hole is four, described through hole is two, be respectively small through hole 61, large through-hole 62, multiple described first-class metering-orifices 18 are arranged in order and change from small to big in aperture, the first-class metering-orifice 18 of aperture maximum is communicated with described small through hole 61, described small through hole 61 and the mutual conducting of large through-hole 62, and the aperture of described small through hole 61 is less than the aperture of large through-hole 62.This kind of mode also can guarantee the adjusting that gas output is ascending.
First first inlet hole 6 is first grade, second the first inlet hole 6 is second gear, the rest may be inferred, the 6th the first inlet hole 6 is the 6th grade, this gas valve has six regulation stalls, and every next gear is all large than a upper gear gas output, and combustion temperature is corresponding to raise gradually, slewing gear rotates rotary spool 5, makes one of them first inlet hole 6 on rotary spool 5 be communicated with described the first gas-entered passageway 3.Be in the embodiment of combination of blind hole and through hole at the first inlet hole 6, in the time that the first gas-entered passageway 3 is communicated with blind hole, gas enters center hole 20 through the first gas-entered passageway 3, blind hole, first-class metering-orifice 18, through hole, finally flows out from outlet passageway 4; In the time that the first gas-entered passageway 3 is communicated with through hole, gas enters center hole 20 through the first gas-entered passageway 3, through hole, finally flows out from outlet passageway 4.Be in the embodiment of through hole at the first inlet hole 6, the same while being communicated with through hole with the first gas-entered passageway 3, gas enters center hole 20 through the first gas-entered passageway 3, through hole, finally flows out from outlet passageway 4.
The setting of six gears of the present invention, compare two or three gears, make in fixing temperature regulating range, each grade of adjustable temperature range is meticulousr, avoid user to select gear less than normal to cause food to be difficult to boil, or selected gear bigger than normal to cause combustion gas waste.
When main airway is communicated with suction port 2 and center hole 20, supplementary air flue has also been communicated with suction port 2 and receiving bore 24, supplements the helping air supply air flue of air flue as main airway, with main airway air feed simultaneously.Described supplementary air flue comprises the second inlet hole 9 of multiple settings corresponding to the first inlet hole 6, described the second inlet hole 9 comprises the through hole of at least two blind holes and at least one and receiving bore 24 conductings, is provided with the second metering-orifice 19 being interconnected between adjacent blind hole and between adjacent blind hole and through hole.
The second inlet hole 9 described in the present embodiment equates with the first inlet hole 6 quantity, specifically comprises that blind hole is five, and through hole is one.
The gas that enters into receiving bore 24 enters to center hole 24 through adjustable clearance 21, converges at center hole 24 and the gas of main airway, flows out together from outlet passageway 4.The size of described adjustable clearance 21 regulates by turning micrometer adjusting screw 10 according to the size deviation of the first inlet hole 6, and to guarantee that the total gas output of outlet passageway 4 reaches design load, this adjusting is generally completed before gas valve dispatches from the factory by producer.Described micrometer adjusting screw 10 is provided with the O shape circle 12 that prevents rotary spool 5 interior gas leaks.
Above-mentioned slewing gear is rotating shaft 7, and described valve body 1 afterbody is provided with the valve seat 11 of fixed rotating shaft 7, and in described rotating shaft 7, cover is useful on the back-up ring 13 that rotating shaft 7 is axially fixed in to valve seat 11.Described valve seat 11 is connected with described valve body 1 rear end screw.Described rotary spool 5 is taper, is provided with the spool spring 16 that rotary spool 5 tops is pressed in to valve body 1 inwall between valve seat 11 and rotary spool 5 afterbodys.The end that valve seat 11 is stretched in described rotating shaft 7 is provided with fixture block 22, is also provided with draw-in groove 23 in the end of rotary spool 5, and described fixture block 22 is located in draw-in groove 23, rotates for stirring rotary spool 5.
