Detailed description of the invention
The technical scheme provided this utility model below in conjunction with Fig. 1～Figure 13 illustrates in more detail.
Seeing Fig. 1 to Figure 12, this utility model embodiment one provides a kind of gas nozzle, including nozzle body 7 and regulation
Part 1, nozzle body 7 has combustion gas runner 11 and the air flow channel 6 connected all the time with this combustion gas runner 11；Regulating part 1 is used for adjusting
The circulation area of gas fuel saving runner 11.
Seeing Fig. 1, burner tips is the important component part of burner, and there is screw thread at its two ends, has one end A of arc surface
Being connected with the copper nut of gas-distributing pipe, other end B is connected with the screwed hole of burner, and has 1/4 arc surface tight-lipped with gas-distributing pipe loudspeaker
Closely connected conjunction.
Regulating part 1 can be choke valve or similar structures, and the element that controls of valve arranges the outside of nozzle body.Regulating part
1 can use platy structure, but regulating part 1 is that plug-in connects relative to nozzle body 7.Hereinafter will provide another of regulating part
Plant implementation.
Further, regulating part 1 is positioned at the upstream of air flow channel 6 and combustion gas runner 11 intersection, mixes with air in combustion gas
Before conjunction, the flow of combustion gas is adjusted by regulating part 1.
Herein, the quantity of air flow channel 6 can be a plurality of, but this plurality of air flow channel 6 is protected with combustion gas runner 11 all the time
Hold connected state.In other words, no matter whether combustion gas runner 11 circulation area changes, the air flow channel connected with combustion gas runner 11
6 is indeclinable all the time.After the flow of combustion gas runner 11 is conditioned change, the most do not affect the position of air flow channel 6 with
And state, so that the circulation of air is constant.The circulation of air is constant, then enter the air capacity that gas nozzle carries out burning
It is constant；Regulating part 1 can be with the circulation of regulating gas runner 11, so that the gas quantity entering gas nozzle changes
Become.So, the ratio of air and combustion gas just can change, and meets different air pressure source of the gas regional, different requirement source of the gas
The requirement that air mixture ratio needed for burning is different.
Technique scheme, on the premise of air flow channel 6 is constant, thus it is possible to vary the circulation of combustion gas runner 11, so that
The combusted proportion obtaining combustion gas and air can change.Technique scheme can not only meet different regions and mix fuel and air
The requirement that composition and division in a proportion example is different, also makes a gas nozzle can meet different source of the gas to fuel and air mixture ratio not simultaneously
Same requirement.When changing source of the gas, change when using region all without changing gas nozzle.
Seeing Fig. 2 to Fig. 6, in the present embodiment, regulating part uses following structure: regulating part 1 is platy structure, regulating part 1
It is provided with at least two adjustment hole 72.Seeing Figure 11, the side surface direction of nozzle body 7 is provided with groove 71, groove 71 and combustion gas runner
11 conducting, regulating part 1 is arranged in groove 71, and at least two adjustment hole 72 can selectively with combustion gas runner 11
