The utility model has the advantages that solved the water injection flow fluctuation that the water injection pressure fluctuation caused. The water injection device has the advantages that the water injection device is adjusted by a self mechanism without electricity, constant flow water injection is always kept under the condition of pressure fluctuation of a water injection pump, the electricity charge is saved, the labor intensity of post workers is reduced, and the water injection requirement of a water well is met.
Description
Technical field
The utility model relates to a kind of mechanical self-regulated current stabilization amount device, belongs to oil-gas field development water injection technology field.
Background technology
In oilfield exploitation, need be measured various media, especially in meticulous the injecting process, individual well requires the flow that keeps constant, injecting flow is not injected the fluctuation of pump pressure and is significantly changed, traditional way is the pressure self-controlled flow instrument that adopts electricity to drive, and by the size of sensor sensing injected water flow, comes adjustment actuating mechanism to regulate and keeps constant flow.And mechanical flow self-regulating device is to rely on the structural principle of self to carry out Flow-rate adjustment, do not need electricity to drive, executing agency, the sensor element, simple to operation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of mechanical self-regulated current stabilization amount device, for the oil-field flooding pressure oscillation, causes the individual well water injection rate to change and design, and this invention has solved the requirement of current stabilization amount water filling.
A kind of mechanical self-regulated current stabilization amount device, housing has upper chamber, lower chamber, the housing upper end connects upper end cover, upper end cover connects an end of water inlet pipe, in the upper chamber of housing, there is the reducing piston to connect, housing has delivery port to be connected with outlet pipe, and the reducing piston connects the regulating spool of chamber under housing, and an end of regulating spool connects valve core spring; The bottom of housing connects the packed-piston seat, and the packed-piston seat connects adjusting screw and spring, and the bottom of housing has water inlet to connect the other end of water inlet pipe.
The utility model has the advantages that and solved the injection flow fluctuation that the water injection pressure fluctuation causes.Rely on self mechanism's adjusting, do not need electricity consumption, in water filling pump surge situation, remain constant flow water injection, by this device, both saved the electricity charge, alleviated again post workman's labour intensity, met the waterflooding requirement of well.
The accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of mechanical self-regulated current stabilization amount device, housing 1 has upper chamber, lower chamber, housing 1 upper end connects upper end cover 2, upper end cover 2 connects an end of water inlet pipe 9, in the upper chamber of housing 1, has reducing piston 3 to connect, and housing 1 has delivery port to be connected with outlet pipe 4, reducing piston 3 connects the regulating spool 5 of 1 time chamber of housing, and an end of regulating spool 5 connects valve core spring; The bottom of housing 1 connects packed-piston seat 7, and packed-piston seat 7 connects adjusting screw 8 and spring 6, and the bottom of housing 1 has water inlet to connect the other end of water inlet pipe 9.
Under usually working, adjusting screw 8 is in a certain permanent position, water enters intake chamber to regulating spool 5 by water inlet, arrive again delivery port, when water injection pressure increases, it is large that the aperture of regulating spool 5 will become, cause flow to increase, this is that this device will be exerted pressure to reducing piston 3 by the reflux pipeline on side, on, although lower chamber pressure rating is identical, but owing to being reducing, on narrow and small greatly, to produce pressure differential, cause regulating spool 5 to move downward, the compression valve core spring, when spring force and piston pressure are poor equate after, regulating spool 5 will rest on a certain permanent position, opening ratio diminishes in earlier stage, but because pressure increases, the aperture successor that diminishes keeps flow constant, reach constant flow water filling purpose, spring force is wherein selected according to the reducing size of piston.When pressure decreased, effect in the other direction, keep flow constant equally.
As mentioned above, embodiment of the present utility model is explained, but, as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
