Abstract
The utility model relates to an automatic adjusting constant water nozzle, relating to the automatic control field of the water injection well of the oil exploitation. The automatic adjusting constant water nozzle is composed of an inlet pipe 1, a pressure cap 2, a spraying nozzle 4, a piston body 6, a spring 7, etc. The top end of the casing 5 is communicated with the inlet pipe 1; the side wall of the casing 5 is provided with a bar-shaped opening 10 which is connected with an outlet pipe 9; the spring 7 is arranged in the casing 5; one end of the spring 7 is provided with the piston body 6, and the other end of the spring 7 is provided with a bottom block 8; the spraying nozzle 4 is fixed in the inner cavity of the casing 5 by the pressure cap 2; the pre-compressed spring force of the spring 7 is utilized to balance the front and the back differential pressure of the water nozzle to be a constant; through that the flow quantity of the water nozzle passing through the determined hole diameter is a constant quantity, the purpose of automatically adjusting the constant quantity is obtained.
Description
Relate to the field
The utility model relates to oil exploitation water injection well automation field, specifically, is a kind ofly can adjust the constant basis water nozzle automatically.
Background technology
In the oilfield exploitation, in order to replenish subsurface pressure, need be to underground flooding.Along with underground crude oil constantly by extraction ground, need to divide adjust water injection rate a period, but require that in the same period water injection rate is constant.
The water filling choke valve that uses is controlled because of being subjected to flood pattern pressure and strata pressure variable effect bigger water injection rate now, need often monitor and readjust, can not guarantee that water injection rate is accurate, China Patent No. is that ZL030102036.8 discloses a kind of petroleum recovering water filling flow control valve, mainly by valve body, the front and back gland, main valve plug, main valve housing, balancing spring, regulating spool, the hydro-cushion part, actuating element and location lockable mechanism are formed, its complex structure adjusting range is subjected to the influence of spring thrust steady state value, and be restricted, and the cost height, can not reach zero in cut-off state and reveal.
Technology contents
The purpose of this utility model is to provide a kind of automatic adjustment constant basis water nozzle, and it utilizes the pressing spring power of giving of spring pressure device to come balance water nozzle front and back pressure reduction is a constant, and making the flow by determining the aperture water nozzle is constant, reaches the purpose of automatic adjustment constant.
The utility model is to realize like this
Comprise that inlet tube 1, pressure cap 2, sealing ring 3, water chew 4, housing 5, piston body 6, spring 7, the end are stifled 8, outlet 9, strip shape gob 10, housing 5 tops are connected with inlet tube 1, the sidewall of housing 5 has strip shape gob 10, strip shape gob 10 links to each other with outlet 9, spring 7 is housed in the housing 5, one end of spring 7 is a piston body 6, and the other end is to block up 8 in the end, and pressure cap 2 is fixed on nozzle 4 inner chamber of housing 5.
The utility model also adopts following technical scheme:
Water nozzle 4 is provided with sealing ring 3.
Water nozzle 4 can be dismantled.
Advantage of the present utility model is: utilize the pressing spring power of giving of spring pressure device to come that pressure reduction is a constant before and after the balance water nozzle, making the flow by determining the aperture water nozzle is constant, thereby reaches the purpose of automatic adjustment constant.
Description of drawings
Fig. 1 is a structural representation of adjusting the constant basis water nozzle automatically.
The specific embodiment
As shown in Figure 1, fluid is from the endoporus of inlet tube 1 pressure cap 2, nozzle 4, piston body 6 enter outlet 9 with the sheared edge of housing strip shape gob 10, when fluid when being a certain amount of, piston body 6 has certain aperture with the sheared edge of strip shape gob 10, and fluid will produce a pressure differential deltap P in piston body 6 front and back this moment, simultaneously, piston body 6 is subjected to the tension force effect of spring 7, Δ P and spring 7 equalization of strains when the fluid constant, and piston body 6 has certain aperture with the sheared edge of strip shape gob 10.When fluid pressure changed, Δ P also can correspondingly change.When Δ P increased, pressure differential will promote piston body 6 displacements diminished the piston body 6 and the sheared edge of strip shape gob 10, and suppressing flow increases, till the tension force of fluid pressure and spring 7 reaches balance again.
Otherwise when Δ P reduced, piston body 6 became big with the sheared edge of strip shape gob 10, and the inhibition flow reduces, thereby reaches the purpose of automatic adjustment constant current amount.
Water chews 4 for dismountable.According to different flow, select for use the different water of internal diameter to chew.
