Specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As illustrated, the oxygen rifle pipette tips in this utility model, including from the inside to the outside successively spaced oxygen catheter 1, in
Between sleeve pipe 2 and gun body outer tube sleeve 3,1 end of the oxygen catheter is connected with a point oxygen disk 4, and 2 end of the intermediate casing is connected with
Deflector 5,3 end of gun body outer tube sleeve are connected with pipette tips end cap 7 by intermediate connector 6, set on the pipette tips end cap 7
There is the jetting oxygen tube 8 being connected with point oxygen disk 4, the deflector 5 is made up of nonmetallic materials and its surface is streamlined.
Specifically, fairshaped deflector 5 can reduce the water resistance which is subject to, and make deflector near wall water velocity point
The uniformity of cloth is improved, and effectively prevent because there is local low speeds flow region and caused pipette tips burn-through problem；Water conservancy diversion
Plate 5 is made using nonmetallic materials, can not only improve the cooling capacity of pipette tips, increases the cooling uniformity of pipette tips, moreover it is possible to enter one
Step reduces manufacture difficulty, so as to realize the reduction of production cost.
Used as the further improvement of such scheme, the deflector 5 is by ruggedness nylon, PPSF/PPSU materials, PC materials
One or more in material, ULTEM9085 materials and PC-ABS are made.This portion of material has heat-resisting, impact resistance strong, fire-retardant
The features such as property good, good processability；Made using injection moulding or 3D printing, efficiently solve material cost and manufacturing cost compared with
It is high, it is difficult to for the problem of engineering practice, streamlined water conservancy diversion can be realized on a large scale on the premise of oxygen rifle pipette tips cost is not increased
The commercial Application of plate.
Used as the further improvement of such scheme, the deflector 5 is inserted on intermediate casing 2 by slot, deflector
It is bonding by high-temp glue between the jetting oxygen tube through deflector, can effectively reduce the installation difficulty of deflector 5.For the ease of dress
Match somebody with somebody, also deflector 5 can be divided into polylith manufacture, each piece of deflector is respectively charged in pipette tips during assembling, to each other using glue
Bonding mode connects.
Used as the further improvement of such scheme, the intermediate connector 6 is Copper steel cladding material.Specifically, in the middle of this
Connector 6 can be made using compression casting, and when adopting compression casting, copper steel joint is for zigzag；The 3D printing system of may also be employed
Into.Extra increased intermediate connector 6 can easily realize the assembled in situ of pipette tips and the body of a gun, when being connected using intermediate connector 6,
The copper end of intermediate connector 6 is welded with pipette tips end cap 7, and steel end and the gun body outer tube sleeve 3 of intermediate connector 6 are welded.Which has
The problems such as effect solves steel plant's scene pipette tips, big body of a gun copper steel heterogeneous material welding difficulty, poor welding quality, greatly reduces
Pipette tips and gun body Site Welding difficulty, improve bonding strength and service life.In addition, can also be by intermediate connector 6 be done
Into different size, to solve to shorten and make what whole oxygen rifle length shortened to ask due to changing the body of a gun caused by pipette tips during use
Topic.
As the further improvement of such scheme, spray oxygen protection section on the jetting oxygen tube 8, is additionally provided with.The spray oxygen protection section can
For be arranged on 8 exit of jetting oxygen tube and center for straight tube boss, also can be directly the straight tube for being arranged on 8 exit of jetting oxygen tube
Section, now straight length is integrated with pipette tips end cap 7.When 8 outlet cone section of pipette tips jetting oxygen tube occurs ablation, due to the protection section
Presence, can make the ablation first occur at the position, effective protection 8 outlet cone section of jetting oxygen tube exempts from scaling loss.
Used as the further improvement of such scheme, 7 outer face of pipette tips end cap is provided with antiradiation coating.The coating can
