Embodiment 1：Combined type pair with a water nozzle top cover 1, four water nozzle cell cubes 2 and a composition of water nozzle tail-hood 3
As a example by water nozzle is streamed in punching, the utility model is described in further detail.
Refer to Fig. 1.The utility model combination delta hedge delta streams water nozzle mainly by a water nozzle top cover 1, four water nozzle units
Body 2 and a water nozzle tail-hood 3 are constituted.The equivalent diameter of water nozzle minimum flow area is 4mm, water nozzle cell cube external diameter 12mm, pacifies
After dress, water nozzle repeatedly streams the runner that liquidates with injection well downhole flow regulator inwall composition.Keyway 5 is coordinated with first water nozzle cell cube key 6 so that
Eccentric circular hole 4 and first water nozzle cell cube cylinder groove 8 are in UNICOM's state.First water nozzle cell cube keyway 7 and second
Individual water nozzle cell cube key 6 coordinates so that first water nozzle cell cube groove 13 and second water nozzle cell cube groove 8 are in UNICOM's shape
State, and first water nozzle cell cube cannelure 9 and second water nozzle cell cube top planes closing form circular passage.With such
Push away, the 3rd, the 4th water nozzle cell cube is connected to be formed with upstream respectively.4th water nozzle unit
Body keyway 7 is engaged with water nozzle tail-hood key 14 makes runner be ultimately at conducting state.
Injection water flows into water nozzle cell cube 2 along eccentric orfice 4, and then the process for entering cannelure 9 with cylinder groove 8 is accompanied by
The vertical change and the sudden expansion of flow section of flow direction.Injection water is turned back respectively and enters groove 10 and 11, and passes through cannelure 12
Make two path water liquidate to converge at groove 13 and then flow into next water nozzle cell cube.And so on after four times, injection water is through partially
Heart slotted eye 15 is discharged.
It is 10m in injected water volume3During/d, the water nozzle that liquidates is streamed in the combination with four water nozzle cell cubes 2, its pressure loss
About 1.393MPa.Under the same terms, the pressure damage of the mono- straight circular hole water injection well chokes of diameter 2mm Wei not 1.225MPa.As can be seen here,
The utility model combination delta hedge delta streams water nozzle and can reach in the case where ensureing minimum flow area equivalent diameter not less than 4mm
And the restriction effect of straight circular hole mono- more than diameter 2mm.Therefore, under identical condition of water quality, the utility model liquidates and streams water nozzle
Traditional single straight circular hole water injection well choke can be substituted, and there is more preferable anti-blocking performance.
