Description
Technical field
The invention belongs to can be used for aerospace, civilian, igniting and field of combustion technology, make more particularly to a kind of high temperature
With replaceable ignition flame radial spray device.
Background technique
Ignition flame injection apparatus is widely used in aerospace, 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 mostly uses greatly sub-thread fiery
Flame diffuser structure or double outlet hole structures, due to the limitation of structure, the flame injection direction of sub-thread flame injection device is general
It is parallel with fuel (or propellant) injection direction, double outlet opening flame injection device injection directions and fuel jet orientation angle compared with
It is small, generally no greater than 30 degree, it is unfavorable for the diffusion and energy transmission of ignition flame, ignition flame scarce capacity makes firing delay
Time is longer.Meanwhile ignition flame injection apparatus is generally only used for temperature lower than in the environment of melting point metal, and it is high to be used for temperature
When under the combustion gas environment of melting point metal, once ablation occurs, can not dismounting and change, therefore limit it using field.
Summary of the invention
Technical problem solved by the present invention is overcoming the shortage of prior art, a kind of replaceable igniting fire of applied at elevated temperature is proposed
Flame radial spray device solves the problems, such as that ignition flame jet power is insufficient, by change flame spray angle enhance flame to
The energy transmission of fuel improves igniting reliability so as to shorten firing delay.Simultaneously by connection type be designed to be threadedly coupled+
Cross-shaped groove structure solves the problems, such as the device under high temperature environment since ablation is not easy to replace.
The technical scheme is that: a kind of replaceable ignition flame radial spray device of applied at elevated temperature, including flame injection
Hole, connection screw thread, cross recess, installing technological hole；The device passes through the connection screw thread that inlet outer surface is arranged in and external dress
Connection is set, the inside with connection screw thread same axial position is cross recess, which is provided with flame spray-hole；?
The outside in exit is equipped with fabrication hole；Before test, installing technological hole is inserted by tooling and passes through connection screw thread for the device
It is mounted in relevant apparatus, tests process Flame from entrance and enter through flame spray-hole jet flames around, after test
Cross recess being inserted by tooling, this device is dismantled gets off.
The flame spray-hole is radial distribution, and quantity is 6.
The invention has the following advantages over the prior art: the device is by being arranged 6 radial holes in spray face downstream
Realize flame radial spray, it is vertical with propellant jet direction, compared with existing injection apparatus, sprayed in improved device
Flame out enhances shock, atomization and mixing to propellant, can realize while light a fire in wide area, more have
The diffusion combustion of sharp flame, increases ignition ability significantly.So as to shorten firing delay, igniting reliability is improved.
After realizing ignition function, the injection bore portion of the device is burned off under high temperature environment, and it is low to be located in tail portion
Threaded connection+cross-shaped groove structure of warm area preserves, and before igniting next time, can be inserted into cross recess by tooling will burn
The ignition flame injection apparatus of erosion disassembles, and replaces with new ignition flame injection apparatus.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is schematic structural view of the invention left view.
Specific embodiment
As shown in Figure 1, 2, the replaceable ignition flame radial spray device of a kind of applied at elevated temperature, including flame spray-hole 1, company
Connect screw thread 2, cross recess 3, installing technological hole 4；The device passes through the connection screw thread 2 and external device (ED) that inlet outer surface is arranged in
Connection, the inside with 2 same axial position of connection screw thread is cross recess 3, which is provided with flame spray-hole 1；
Fabrication hole 4 is installed in the outside in exit；Before test, pass through tooling be inserted into installing technological hole 4 and by connection screw thread 2 should
Device is mounted in relevant apparatus, is tested process Flame from entrance and is entered through the jet flames around of flame spray-hole 3, tries
Cross recess can be inserted by tooling after testing, and this device is dismantled gets off.The flame spray-hole 1 is radial distribution, and quantity is 6.
Ignition flame lights fuel or propellant by six radial injections outward of flame spray-hole 1 in spray face downstream,
Six radial flame spray-holes 1 keep flame injection direction vertical with propellant jet stream, and due to the variation of sectional area, flame passes through
When flame spray-hole 1, flow velocity refers to 2~3 times, and improve flame extends transversely through power, makes shock, mixing of the flame to fuel
More sufficiently, it can realize while light a fire in wide area, promote the diffusion combustion of flame, to improve ignition energy
Power shortens firing delay.Six flame spray-hole holes 1 are located at high-temperature area, in fuel or propulsion after realizing ignition function
Agent combustion phases is burned off.
The connection screw thread 2 of tail portion is connect with external device (ED), realizes the igniter and external device (ED) by installing technological hole 4
Tighten and connect.The tail portion of the device is arranged in connection screw thread 2, and the low-temperature region in spray face upstream avoids high temperature
Environment, protection flank will not be damaged because of hot environment.As shown in Fig. 2, cross recess 3 is equipped with inside connection screw thread 2, under
Before secondary igniting, cross recess 3 can be inserted by tooling and disassemble the ignition flame injection apparatus of ablation, replaced with new
Ignition flame injection apparatus.
The above is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, it is all according to
According to technical spirit any simple modification, equivalent change and modification to the above embodiments of the invention, still belong to the present invention
The protection scope of technical solution.
