Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
As it is shown in figure 1, a kind of annular flow nozzle, including sleeve pipe 1 and oil inlet pipe 2, sleeve pipe 1
Offer the installation passage 11 running through sleeve pipe 1 two ends；Oil inlet pipe 2 includes oil-feed section 21, goes out
Oil section 23 and the breeze way 22 being connected between described oil-feed section 21 and described fuel-displaced section 23；
Described breeze way 22 connects with described oil-feed section 21 and described fuel-displaced section 23 respectively；Described slow
The internal diameter of the section of punching 22 and external diameter are all gradually increased from oil-feed section 21 to the direction of fuel-displaced section 23；
Described oil-feed section 21 is formed away from one end of breeze way 22 and is provided with the oil inlet end of oil-in 211；
Described fuel-displaced section 23 one end away from breeze way 22 forms the oil outlet end being provided with oil-out 231；

The flowing water interstitial area 3 that water passes through；Described sleeve pipe 1 offers and flowing water near the side of oil inlet end
The water inlet 4 of interstitial area 3 connection.Viscous crude enters in oil-feed section 21 from oil-in 211, thick
Oil flows to breeze way 22, and the transport space of viscous crude changes from small to big, by oil-feed section 21 viscous crude pair
The pressure that breeze way 22 viscous crude produces, the flowing making viscous crude is more stable；Meanwhile, current from
Water inlet 4 enters, the flowing water interstitial area 3 at buffered section of 22 places, the flowing water gap of this section
District 3 transport space from large to small, reduces the flow velocity of current, thus reduces many for fuel-displaced section
The water flow pressure of the flowing water interstitial area 3 corresponding to 23, the flowing making current is more stable；Thick
Oil and current tend towards stability state, and combine at oil-out 231, improve aqueous phase bag
Wrap up in the stability of the nowed forming of oil phase, and then improve the conveying quality of aqueous phase parcel oil phase；By
Preferably wrap viscous crude in aqueous phase, reduce the flow resistance coefficient before viscous crude and sleeve pipe 1, and then
Improve conevying efficiency.This utility model passes through breeze way 22, makes oil-feed section 21 to breeze way 22
Pressure less, the flow velocity of viscous crude can be reduced；In actual use, the speed of viscous crude is the fastest
In current, and in the case of the bore holding of oil-feed section 21 and fuel-displaced section 23 is constant, change
The length of breeze way 22 can change the transport space of viscous crude and water, i.e. change viscous crude and current
Relative velocity, and the flow velocity of viscous crude and the length correlation of breeze way 22, current
Flow velocity and breeze way 22 are in inverse correlation relation；When lengthening the length of breeze way 22, the stream of viscous crude
Dynamic space diminishes, and speed reduces；The space of current flowing becomes big, and speed increases；By rationally
The length of design breeze way 22, can make viscous crude tend to balance with the flow velocity of current, and increases water

Described breeze way 22 is tapered, and the tapering of described breeze way 22 is 4 °, according to secondary reality
Behaviour learns, when the tapering of breeze way 22 is 4 °, viscous crude tends to balance with the flow velocity of current,
And the flow velocity of current is the most very fast.
Preferably, described oil-feed section 21 and described fuel-displaced section 23 all in hollow cylindrical, make thick
Oil and the current flow velocity in these two sections keeps constant, improves viscous crude and the mean flow rate of current,
Improve conevying efficiency further.
In the present embodiment, described connector is fuel inlet fitting 5, and described fuel inlet fitting 5 is sheathed also
Being fixed in oil-feed section 21, described fuel inlet fitting 5 outer wall offers the first external screw thread, described
One end of sleeve pipe 1 offers the first female thread mated with described first external screw thread, extraneous fuel feeding
Equipment is sealed by flexible pipe etc. and inserts or be socketed on fuel inlet fitting 5, makes viscous crude will not be mixed into flowing water
Interstitial area 3；Meanwhile, easy for installation, save the set-up time.
The pipeline section that described sleeve pipe 1 is corresponding with breeze way 22 is hollow cylindrical, it is ensured that water flows to
When the position, flowing water gap 3 at breeze way 22 place is put, current flowing space from large to small,
Current are made to be buffered.
Described sleeve pipe 1 is outward extended with a water inlet pipe 6, and described water inlet pipe 6 is away from sleeve pipe
One end of 1 forms the water inlet end being provided with described water inlet 4, is more conducive to seal and installs external world's water inlet
Device and this annular flow nozzle, improve sealing.
The bore of described oil-feed section 21, less than the bore of described water inlet pipe 6, increases current
Flow, the water in current extruding flowing water interstitial area 3, accelerate the flow velocity of current, more preferably parcel is thick
Oil, improves shipping mass and efficiency further.
It will be apparent to those skilled in the art that can technical scheme as described above and structure
Think, make other various corresponding changes and deformation, and all these changes and deformation
Within all should belonging to this utility model scope of the claims.
