Description
Technical field
The invention belongs to can be used for Aero-Space, civilian, igniting and field of combustion technology, make more particularly to a kind of high temperature
With replaceable ignition flame radial spray device.
Background technology
Ignition flame injection apparatus is widely used in Aero-Space, civilian, igniting and field of combustion technology, such as igniter
The device that downstream is connected with fuel (or propellant).The flame injection device in existing igniter downstream uses sub-thread fire mostly
Flame anemostat structure or double outlet hole structure, due to the restriction of structure, the flame injection direction of sub-thread flame injection device is general
Parallel with fuel (or propellant) injection direction, double outlet opening flame injection device injection directions are with fuel jet orientation angle relatively
Little, generally no greater than 30 degree, it is unfavorable for that the diffusion of ignition flame is transmitted with energy, ignition flame scarce capacity makes firing delay
Time is longer.Meanwhile, ignition flame injection apparatus is typically only used for temperature less than in the environment of melting point metal, high for temperature
Time under the combustion gas environment of melting point metal, once there is ablation, it is impossible to dismounting and change, therefore limit its use field.
Summary of the invention
Present invention solves the technical problem that and be: overcome prior art not enough, propose a kind of applied at elevated temperature replaceable igniting fire
Flame radial spray device, solves the problem that ignition flame jet power is not enough, by change flame spray angle strengthen flame to
The energy transmission of fuel, thus shorten firing delay, improve igniting reliability.Connected mode is designed to simultaneously threaded+
Cross-shaped groove structure, solves this device in high temperature environments due to the most easily changeable problem of ablation.
The technical scheme is that: a kind of applied at elevated temperature replaceable ignition flame radial spray device, spray including flame
Hole, connection screw thread, cross recess, installing technological hole；This device is by being arranged on the connection screw thread of porch outer surface and outside dress
Putting connection, be cross recess with the inside being connected screw thread same axial position, this device near exit is provided with flame spray-hole；?
The outside in exit is provided with fabrication hole；Before test, insert installing technological hole and by connecting screw thread by this device by frock
Being arranged in relevant apparatus, process of the test Flame enters through flame spray-hole to surrounding jet flames from entrance, after test
Cross recess can be inserted by frock to be disassembled by this device.
Described flame spray-hole is radial distribution, and quantity is 6.
The present invention compared with prior art has the advantage that this device by arranging 6 radial holes in downstream, spray face
Realize flame radial spray, vertical with propellant jet direction, compared with existing injection apparatus, the device after improvement sprays
Flame out enhances the shock to propellant, is atomized and mixes, and can realize lighting a fire simultaneously, more have in wide area
The diffusion combustion of profit flame, makes ignition ability significantly increase.Thus shorten firing delay, improve igniting reliability.
After achieving ignition function, the spray-hole part of this device is burned off in high temperature environments, is located in afterbody low
Threaded+the cross-shaped groove structure of warm area preserves, and before next time lights a fire, can insert cross recess by frock and will burn
The ignition flame injection apparatus of erosion disassembles, and replaces with new ignition flame injection apparatus.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is present configuration schematic diagram left view.
Detailed description of the invention
As shown in Figure 1, 2, a kind of applied at elevated temperature replaceable ignition flame radial spray device, including flame spray-hole 1, even
Connect screw thread 2, cross recess 3, installing technological hole 4；This device is by being arranged on connection screw thread 2 and the external device (ED) of porch outer surface
Connecting, be cross recess 3 with the inside being connected screw thread 2 same axial position, this device near exit is provided with flame spray-hole 1；
In the outside in exit, fabrication hole 4 is installed；Before test, by frock insert installing technological hole 4 and by connect screw thread 2 should
Device is arranged in relevant apparatus, and process of the test Flame enters through flame spray-hole 3 to surrounding jet flames, examination from entrance
Cross recess can be inserted by frock after testing to be disassembled by this device.Described flame spray-hole 1 is radial distribution, and quantity is 6.
Ignition flame is outwards sprayed by six radial direction flame spray-holes 1 in downstream, spray face, lights fuel or propellant,
Six radial direction flame spray-holes 1 make flame injection direction vertical with propellant jet, and due to the change of sectional area, flame passes through
During flame spray-hole 1, flow velocity refer to 2～3 times, and improve flame extends transversely through power, makes flame to the shock of fuel, mixing
More abundant, can realize lighting a fire in wide area simultaneously, promote the diffusion combustion of flame, thus improve ignition energy
Power, shortens firing delay.Six flame spray-hole holes 1 are positioned at high-temperature area, in fuel or propelling after realizing ignition function
Agent combustion phases is burned off.
The connection screw thread 2 of afterbody is connected with external device (ED), realizes this igniter and external device (ED) by installing technological hole 4
Tighten and connect.Connect screw thread 2 and be arranged on the afterbody of this device, be in the low-temperature region of upstream, spray face, avoid high temperature
Environment, protection flank will not damage because of hot environment.As in figure 2 it is shown, be provided with cross recess 3 connecting inside screw thread 2, under
Before secondary igniting, cross recess 3 can be inserted by frock and the ignition flame injection apparatus of ablation is disassembled, replace with new
Ignition flame injection apparatus.
The above, be only presently preferred embodiments of the present invention, and the present invention not makees any pro forma restriction, every depends on
Any simple modification, equivalent variations and the modification made above example according to the technical spirit of the present invention, the most still belongs to the present invention
The protection domain of technical scheme.
