Embodiment
Before describing the embodiments in more detail, it should be understood that the invention is not restricted to institute hereafter or in accompanying drawing in the application
The detailed construction or arrangement of elements of description.The present invention can be the embodiment that other manner is realized.Furthermore, it is to be understood that this paper institutes
The wording and term used is solely for describing purposes, should not the explanation of being construed as limiting property." comprising " used herein, "comprising",
The similar wording such as " having " is meant comprising items listed thereafter, its equivalent and other additional things.Particularly, description is worked as
When " certain element ", the quantity that the present invention does not limit the element can also include multiple as one.
Fig. 1 is the cross-sectional view that distribution pipe is straight tube, as shown in figure 1, the present invention provides a kind of isometrical constant pressure pipe
10, including a distribution pipe 12 with uniform bore diameter, house inner core 14 in distribution pipe 12, the inner core 14 and the inwall of distribution pipe 12 it
Between formed for flow of fluid runner 16.In the direction of flow, inner core 14 is arranged on the back segment of distribution pipe.In specification and right
In it is required that, " back segment " is meant, the part in the direction of flow away from distribution tube inlet.
In the present embodiment, inner core 14 is cylindric.Inner core 14 may include a section or more piece, and each of which section inner core is
Footpath, and the external diameter of each section inner core is different.Specifically, side of the external diameter of at least one section inner core 14 along flow of fluid
To gradual increase, progressively to reduce the cross-sectional area of runner 16, fluid is reduced on the length direction of distribution pipe 12 so as to reach
The purpose of pressure change.
It should be pointed out that in other embodiments, inner core 14 can also be other shapes, such as square, as long as can drop
Pressure change of the low fluid on the length direction of distribution pipe 12.
In the present embodiment, distribution pipe 12 is straight tube, and inner core 14 includes three sections, and the external diameter of the three sections inner core is along flow of fluid
Direction gradually increases, and inner core 14 is fixedly installed in distribution pipe 12, such as sets support by inner core 14 on the inwall of distribution pipe 12
It is fixed.
Fig. 2 is the schematic perspective view for the injection type burner that distribution pipe is ring pipe, and Fig. 3 is that distribution pipe is cutd open in Fig. 2
Face structural representation.As shown in Figures 2 and 3, the present invention provides a kind of injection type burner, including air inlet pipe 20, with air inlet
The distribution pipe 22 that pipe 20 connects, is arranged at some venturi burners being spaced apart in distribution pipe 22, and be arranged at distribution pipe
Inner core 26 in 22.In fig. 2, it is clear to illustrate, only draw the nozzle 24 of each venturi burner.The inner core 26 and distribution
Runner 28 is formed between the inwall of pipe 22, distribution pipe 22 is that some venturi burners 24 provide fluid fuel, some venturi combustions
The fluid fuel that burner 24 provides to burning charge pipe 20.
In the present embodiment, inner core 26 is cylindric.Equally, inner core 26 may include a section or more piece, and each section is isometrical
, and the external diameter of each section inner core is different.Specifically, this at least one section inner core 26 external diameter along fluid flow direction by
It is cumulative greatly to reduce the cross-sectional area of runner 28, the cross-sectional area of runner 28 reduces the pressure increase for causing fluid, in certain journey
The pressure that fluid reduces because constantly consuming is offset on degree, so as to ensure the stability of Fluid pressure.
It should be pointed out that in other embodiments, inner core 26 can also be other shapes, such as square, as long as can drop
Pressure change of the low fluid on the length direction of distribution pipe 22.
Distribution pipe 22 is ring pipe, and inner core 26 is arranged on ring pipe back segment, i.e., is connected away from distribution pipe 22 with air inlet pipe 20
In one section of the present embodiment at place, because the length of distribution pipe 22 is shorter, the change in fluid pressure in distribution pipe 22 is relatively small, because
This, inner core 26 only sets a section, and inner core 26 is the arc of the adaptation ring pipe.Fluid enters distribution pipe 22 through air inlet pipe 20
In, and flowed into simultaneously from ring pipe both ends.Therefore, inner core 26 is symmetrically fixedly installed in distribution pipe 22, such as in distribution pipe
Support is set to fix inner core 26 on 22 inwalls.
It should be noted that when the length of distribution pipe is longer, inner core can be set to more piece (not shown).The more piece
Inner core is arc, and the external diameter of the more piece inner core gradually increases along fluid flow direction, and tube fluid is distributed to reduce with this
Pressure differential, and then the stability of venturi burner flame burning is kept, and the more piece inner core is with the axial direction of air inlet pipe
It is symmetrical for symmetry axis.
In summary, the present invention provides a kind of isometrical constant pressure pipe and injection type burner.Set in isometrical pipeline
At least one section inner core, each section inner core are isometrical, are formed between at least one section inner core and inner-walls of duct and supply flow of fluid
Runner, it is described at least one section inner core external diameter gradually increase along flow direction to reduce pressure of the fluid in pipe lengths
Power changes, so as to ensure that the stability of all venturi burner flame burnings.Isometrical constant pressure pipe knot provided by the invention
Structure is simple, easily installation processing, and cost is cheap, application easy to spread.
Concepts described herein may be embodied to other forms in the case of without departing from its spirit and characteristic.It is disclosed
Specific embodiment should be considered as exemplary rather than restricted.Therefore, the scope of the present invention be by appended claim,
Rather than it is determined according to these descriptions before.Any change in the letter of claim and equivalency range is all
The scope of these claims should be belonged to.
