Coordinate nested composition with outer sleeve, the tube wall surface of outer sleeve is provided with uniform manhole, at middle sleeve and inner sleeve
Tube wall surface on be provided with uniform manhole, and on the outer wall of middle sleeve and inner sleeve, be machined with U-shaped groove, each
Through hole constitutes a fluid passage with many places corner from sleeve assembly outer wall to inwall with corresponding U-shaped groove.With
As a example by the constant-current water injection engineering of oil field: during the well head dispensing of injection well, if pipeline is bored a hole suddenly, leakage or pump are stopped transport
Stopping note, can cause problems with, one is to cause the fluid media (medium) injected in pit shaft to return Tuhe crossfire；Two is to cause outer discharge to increase
Greatly, environment is polluted.Thus directly affects the working performance of oil field constant-current water injection.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of sleeve with one-way flow effect
Regulation valve.
This utility model adopts the following technical scheme that a kind of single current, to sleeve adjusting valve, including valve body, is arranged in valve body
The inner sleeve in portion and outer sleeve, also include the vertically extending regulating valve stem of axis that split is arranged and be arranged at regulation valve
The spool being used for matching with valve port on bar, spool can move up and down relative to regulating valve stem, described spool and regulating valve stem
Between be provided with back-moving spring, the elastic force bottom spool at back-moving spring moves downward with close port.
It is provided with spool location bar or spool positioning sleeve on described spool, described regulating valve stem is provided with and positions with spool
Spool positioning sleeve or valve rod that bar or spool positioning sleeve match position bar.
Described valve body be internally provided with valve seat, described valve port is arranged on valve seat.
Described spool is the mushroom-head shape that the valve port opening and closing with valve seat coordinates.

Detailed description of the invention
A kind of single current to the embodiment of sleeve adjusting valve as it is shown in figure 1, outside including valve body 1, being arranged in valve body 1 inner chamber
Sleeve 7, inner sleeve 6, it is arranged at the regulating valve stem 8 within inner sleeve 6 and split is arranged at the spool 3 of regulating valve stem 8 lower end.Valve
Being provided with fluid feed channel 9 and fluid outlet passage 10 on body 1, the inner chamber of valve body 1 flows out with fluid feed channel 9 and fluid
Passage 10 is connected, valve body 1 be internally provided with valve seat 2, valve seat 2 offers valve port.Spool location bar it is provided with on spool 3
5, as in figure 2 it is shown, the screw mandrel that the upper end of regulating valve stem 8 is the screwed fluid pressure size passed through for regulation, regulation
The lower end base of valve rod 8 is provided with the spool 3 that makes inserted for spool location bar 5 and can move up and down relative to regulating valve stem 8
Spool positioning sleeve, is provided with back-moving spring 4 between spool 3 and regulating valve stem 8, spool 3 is inlaid with the mushroom of industrial ceramics for periphery
Mushroom head shapes, spool 3 is backed down to open valve port under fluid matasomatism so that fluid passes through, it is achieved the regulation of fluid is passed through,
When buffer brake is more than to come water pressure, under the common effect of the elastic force of buffer brake and back-moving spring, spool 3 offsets with valve port
With close port, it is achieved that the function of the single current of this sleeve adjusting valve.
Inner sleeve offers the inner sleeve opening passed through for fluid for 6 weeks on side, as shown in Figure 3-4, inner sleeve circulates
The shape in hole includes circular port 12 and tri-angle-holed 11.The upper end, all sides of outer sleeve 7 offers outer sleeve opening 13, simultaneously
All sides outer wall of outer sleeve 7 is provided with the outer sleeve annular space 14 that axis is vertically extending, makes outer sleeve 7
Cross section is I-shaped, and all sides outer wall of inner sleeve 6 is also equipped with 3 inner sleeve annular spaces from top to bottom, inner sleeve
Between each inner sleeve annular space, it is provided with seal groove 13 on the outer wall of cylinder 6, in seal groove 13, is provided with sealing ring.Valve body 1
Inner chamber and inner and outer sleeves opening and inner and outer sleeves annular space constitute the passage for fluid circulation.Fluid is through inner sleeve
Opening and the misplacement space of regulating valve stem, the outer sleeve annular space of the annular entering back into outer sleeve 7 passes through, it is possible to achieve right
Fluid regulates and controls more accurately.
This single current to the work process of sleeve adjusting valve is: when the valve is open, and regulating valve stem 8 carries by screw mandrel, valve
Core 3 is backed down to open valve port under fluid matasomatism so that fluid passes through inner sleeve opening, then by outer sleeve opening,
The regulation realizing fluid is passed through；When buffer brake is more than to come water pressure, elastic force common of buffer brake and back-moving spring 4
Under effect, spool 3 and valve port offset with close port, it is achieved that this single current is to the function of the single current of sleeve adjusting valve.
In other embodiments of the present utility model, spool can also be provided with spool positioning sleeve, now regulating valve stem
Lower end is provided with the valve rod location bar matched with spool positioning sleeve；Industrial ceramic material can not also be inlayed in the periphery of spool；Valve
Core head can also be spheroid；Spool can be spherical spool, between spherical spool upper end and the lower end of regulating valve stem
It is provided with connection spool and the back-moving spring of regulating valve stem, and eliminates spool location bar and the structure of spool positioning sleeve.
