Abstract
The present invention provides emitter barrel cooling jacket of the kind based on spiral shape turbulence blades, including water jacket ontology, blasthole, apopore；Water jacket ontology is tubular and to be placed on emitter barrel, and blasthole and apopore are located on water jacket ontology both ends on lower wall surface, water jacket inner body wall circumferentially arranged spiral shape water delivery blade from front to back.Its barrel can efficiently be cooled down during emitter continuous fire.
Description
Technical field
The present invention relates to a kind of emitter cooling technology, especially a kind of emitter based on spiral shape turbulence blades
Barrel cooling jacket.
Background technique
Emitter during carrying out continuous fire, barrel constant temperature rise, seriously threaten propellant powder safety and
Barrel service life.Many emitters reduce barrel temperature in such a way that outside is cooling.Traditional external cooling jacket
Middle cooling water flow does not have directionality and regularity, it is easy to form flow dead zone, reduce radiating efficiency；Cooling water flow edge flows over
Temperature is gradually increasing in journey, and lower part cooling effect is relatively poor；It is even that both of which easilys lead to barrel inhomogeneous cooling, makes
It is bent at barrel.
Summary of the invention
The purpose of the present invention is to provide a kind of emitter barrel cooling jacket based on spiral shape turbulence blades, can be with
Its barrel is efficiently cooled down during emitter continuous fire.
Realize the technical solution of the object of the invention are as follows: a kind of emitter barrel cooling water based on spiral shape turbulence blades
Set, including water jacket ontology, blasthole, apopore；Water jacket ontology is tubular and is placed on emitter barrel, blasthole and water outlet
Hole is located on water jacket ontology both ends on lower wall surface, and a circumferentially arranged spiral shape is defeated from front to back for water jacket inner body wall
Wiper blade.
Using above-mentioned water jacket, the screw pitch of the spiral shape water delivery blade is gradually increased from blasthole to apopore direction.
Using above-mentioned water jacket, spiral shape water delivery blade is fixed in water jacket inner body wall and is arranged on side wall and end face several
Protrusion.
Using above-mentioned water jacket, the protrusion on side wall is raised along water jacket body shaft on water jacket ontology radial section and end face
It is triangle to section.
Using above-mentioned water jacket, the both ends of water jacket ontology pass through fixing piece respectively and are detachably connected with emitter barrel.
Compared with prior art, the present invention its remarkable advantage is: (1) cooling water flow covers entire barrel surface, heat dissipation
Area is big；(2) liquid in water jacket is directionally flowed along spiral vane rule, can increase radial vortex, avoids flowing dead
Area；(3) jagged turbulence structure can destroy fluid boundary layer, augmentation of heat transfer on blade；(4) turbulence blades screw pitch is along water jacket axis
To being gradually increased, barrel cooling can be made more uniform；(5) it is connected by screw bolts between each component, facilitates scale removal and maintenance.
The invention will be further described with reference to the accompanying drawings of the specification.
Detailed description of the invention
Fig. 1 is partial 3 d figure of the invention.
Fig. 2 is main view of the invention.
Fig. 3 is top view of the invention.
Fig. 4 is spiral shape water delivery blade result schematic diagram of the invention.
Specific embodiment
In conjunction with Fig. 1 to Fig. 3, a kind of emitter barrel cooling jacket based on spiral shape turbulence blades, including top are solid
Determine part 1, water jacket ontology 5, lower fixture 4, sealing joint washer；Upper stationary part 1 is used for water jacket ontology 5 and barrel top
It is fixed；Water jacket body upper part is provided with blasthole 2, and lower part is provided with apopore 3；Lower fixture 4 is used for water jacket ontology 5 and lower part
Barrel is fixed；Sealing joint washer is installed in each interface；There are spiral shape turbulence blades 7 on water jacket ontology 5.
Cooling water flow covers entire barrel surface in the cooling jacket 5.
Upper stationary part 1 and lower fixture 4 are cylindrical shape, the axially disposed through-hole that emitter barrel passes through altogether,
Emitter barrel passes through through-hole and is sealed by seal washer.Upper stationary part 1 and lower fixture 4 pass through bolt 6 respectively
It is connect with barrel.
The blasthole 2 is mounted on the surface on 5 top of water jacket ontology, and apopore 3 is mounted on 5 lower part of water jacket ontology
Underface.
In conjunction with Fig. 4, spiral shape water delivery blade 7 is fixed on 5 inner wall of water jacket ontology and is arranged on side wall and end face several convex
Play 7-1.Have the spiral shape turbulence blades 7 being axially distributed along water jacket on the water jacket ontology 5, between blade and barrel there are
Gap.Raised 7-1 of the raised 7-1 on 5 radial section of water jacket ontology and end face on side wall is three along 5 axial cross section of water jacket ontology
It is angular.Raised 7-1 is serrated.
The course of work of the invention are as follows:
In emitter preshot, water jacket ontology 5 is fixed on barrel by upper stationary part 1 and lower fixture 4,
Blasthole 2, which connects, enters water interface in cooling back installation, and apopore 3 connects the water outlet mouthpiece in cooling back installation.Shooting course
Starter when beginning, water flow enter cooling jacket by blasthole, are threadingly advanced along water delivery blade around barrel, from apopore
Outflow, achievees the effect that cooling barrel.
