Abstract
The utility model relates to a single-well water injection quantity control valve, and belongs to the technical field of the oil extraction equipment. The control valve is characterized in that a valve seat is fixed in a valve body by a jacking sleeve; a cone sleeve is fixed at one end of a lead screw and is jacked at the water flow hole of the valve seat; the lead screw fits with a bonnet through threads; and the bonnet is fixedly connected with the valve body through thread. The utility model has the advantages of simple structure, convenient use, durability, easy replacement of the valve seat and the cone sleeve, and the like, and greatly reduces the production loss as a result that the original water injection strobe is punctured and damaged.
Description
Technical field
The utility model belongs to the oil production equipment technical field.
Background technology
In oilfield development process, for keeping strata pressure, make steady output of oilwell, generally adopt water injection method to reach the stable yields purpose at present.Because the difference of each well water injection rate, the water injection rate majority of every mouthful of well is regulated and control at distributing room for water injection.Oil-field flooding at present is in the most high pressure sluice valve control water yields of using of distributing room for water injection, effort is consuming time in adjusting the injecting process, valve seat is grown to decrease causes that water injection rate increases gradually in the unit interval, for keeping the regulation water injection rate, the often adjustment valve control water yield, and gate valve is grown the damage back, is not closed completely, and it is frequent to cause changing valve, increase trouble to production management, also strengthened cost of production simultaneously.
Summary of the invention
The purpose of this utility model is:
A kind of individual well water injection rate controlling valve is provided, and it can no longer use original annotation sluice gate control water injection rate, reduces gate and grows damage, prolongs the gate use greatly and receives a mandate.
The technical solution of the utility model is:
Valve seat is fixed in the valve body with tight sleeve, and tapered sleeve is fixed on an end of screw mandrel, and the tapered sleeve overhead is on the valve seat water flow hole, and leading screw and bonnet adopt threaded engagement, bonnet and valve body be threaded fixing.
The beneficial effects of the utility model are:
Simple in structure, easy to use, durable in use, advantages such as valve seat, the easy replacing of tapered sleeve have significantly reduced because the original annotation sluice gate is grown and have decreased the production loss that causes.
Description of drawings
Fig. 1 is the utility model structure sectional view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, wherein, the 1st, leading screw, the 2nd, bonnet, the 3rd, valve body, the 4th, tight sleeve, the 5th, valve seat, the 6th, tapered sleeve, the 7th, seal A, the 8th, seal B, the 9th, locking cap.
The utility model is combined by leading screw (1), bonnet (2), valve body (3), tight sleeve (4), valve seat (5), tapered sleeve (6), seal (7), (8), locking cap (9).Overcoat and tight sleeve are to be threaded, and it is fixed on valve seat in the overcoat and seals with sealing ring (7).Welding is adopted in tapered sleeve and leading screw cooperation place, and screw mandrel and valve body seal with sealing ring (8), and bonnet and valve body are to be threaded, and leading screw and bonnet are threaded engagement.A, B two places and waterflood-transmission line welding.
Clockwise rotating leading screw during use is to close, and rotates counterclockwise to be out.Because the leading screw of this device is carefully to detain screw, when its rotates a circle between valve seat and the tapered sleeve area of passage change lessly, like this, help trace and adjust water injection rate and reach waterflooding requirement, regulate with high pressure valve than present oil field that water injection rate is laborsaving to save time.After water injection rate is set up,, prevent because vibrations changed the current area with the locked leading screw of locking cap.Throttle part be carbide alloy also than high pressure valve anti-taste of damming, use the length of receiving a mandate, reduce the production maintenance cost.
Valve seat is fixed in the valve body with tight sleeve, and tapered sleeve is fixed on an end of screw mandrel, and these two parts materials adopt carbide alloy, improves the anti-water of valve throttling place and grows ability, and leading screw and bonnet adopt thin button screw thread, is to realize fine setting to water injection rate.
Claims (2)
1, a kind of individual well water injection rate controlling valve is characterized in that: valve seat is fixed in the valve body with tight sleeve, and tapered sleeve is fixed on an end of screw mandrel, and the tapered sleeve overhead is on the valve seat water flow hole, and leading screw and bonnet adopt threaded engagement, bonnet and valve body be threaded fixing.
2, a kind of individual well water injection rate controlling valve according to claim 1 is characterized in that: lock leading screw with locking cap.
