Abstract
The utility model discloses an adjustable valve used in an injection pipeline to adjust fluid flow and pressure. The adjustable valve mainly comprises an adjusting arm (1), a sealing device (2), a valve core (3) at a certain taper angle in axial direction with the surface provided with multilevel bulges, and a valve cylinder (4) at the same axial taper angle as the valve core (3) with the side wall provided with an inlet (5) and the bottom provided with an outlet (6), wherein the adjusting arm (1) is in splicing with the sealing device (2) and is fixed with the upper end of the valve core (3); the sealing device (2) is in sealing splicing with the valve core (3) and is in sealing connection with the upper end of the valve cylinder (4); moreover, the side lines of the bulges (7) arranged on the surface of the valve core are broken lines. On the premise of ensuring injection rate, the overall height of the adjustable valve can be reduced to 800 mm; moreover, the cost of the utility model is only one third of that of the prior adjustable valve.
Description
Technical field:
The utility model relates on a kind of oil field control valve from pressure to underground input fluid that regulate flow and, the concrete control valve of being made up of regulating arm, sealing device, valve cylinder, spool etc.
Background technology:
The regulated fluid flow that uses on the poly-pipeline of oil field notes and the control valve of pressure, its spool face is being arranged multistage projection vertically, when polymer solution or other fluids enter control valve from inlet, when flowing out from exporting along the gap of valve cylinder and spool, the protruding convection cell of spool face plays the effect of step-down step by step, regulate the effectively protruding quantity and the size of inlet by the rotation regulating arm, thus the flow and the pressure of control fluid.As shown in Figure 1, existing regulation valve core rat 17 to be shaped as fusiformis spherical, the sideline of projection is slick and sly camber line, at certain-length internal projection negligible amounts, antihypertensive effect is not obvious, for reaching certain step-down requirement, the spool whole height is higher, is generally 1500mm, volume is bigger, heavy, therefore it is more to expend raw material, and cost is higher, also inconvenient during use.
The utility model content:
In order to solve existing technical problem in the background technology, the utility model provides a kind of control valve that is used to annotate poly-pipeline adjusted fluid flow and pressure, and this control valve further reduces cost under the situation that guarantees injection rate, and is easy to use.
For solving the problems of the technologies described above, the control valve that is used to annotate poly-pipeline adjusted fluid flow and pressure of the present utility model, mainly by regulating arm, sealing device, be the spool that certain taper and surface are multistage projection vertically, identical and have the valve cylinder that inlet, bottom have an outlet at sidewall and form to tapering with poppet shaft, wherein regulating arm and sealing device are pegged graft, and fixedly connected on the spool; Sealing device and seal spool are pegged graft, and are sealedly and fixedly connected with the valve cylinder upper end; Spool face projection sideline is polygon broken line.
For spool face projection sideline, be preferable over and choose five edge break lines.
Fixedly connected and sealing device is sealedly and fixedly connected with the valve cylinder upper end for regulating arm and spool upper end, preferred fixedly connected mode is the buckle-type connection.
The utlity model has following beneficial effect: owing to make protruding sideline into polygon broken line by slick and sly camber line, saved because of the spent length of arc transition, make that the quantity of projection increases on the unit length, thereby the step-down number of times increases thereupon on the unit length, therefore this control valve whole height can reduce under the situation that guarantees injection rate, only be 800mm, fabricating cost only is 1/3 of a former control valve.
Description of drawings:
Fig. 1 is the spool face convex shape schematic diagram of background technology.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the enlarged drawing of Fig. 2 rat A portion.
1-regulating arm among the figure, 2-sealing device, 3-spool, 4-valve cylinder, 5-inlet, 6-outlet, 7, the 17-projection.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 2 in conjunction with shown in Figure 3, the control valve that is used to annotate poly-pipeline adjusted fluid flow and pressure of the present utility model, mainly by regulating arm 1, sealing device 2, be certain taper vertically and the surface is multistage protruding 7 spool 3, identical with spool 3 axial taperings and have inlet 5 at sidewall, the bottom has outlet 6 valve cylinder 4 and forms, wherein regulating arm 1 is pegged graft with sealing device 2, be connected with spool 3 upper end buckle-types, certainly being not limited to buckle-type connects, can be that other are fixedly connected, as be threaded etc.; Sealing device 2 is pegged graft with spool 3 sealings, is connected with valve cylinder 4 upper end sealed clamping cleat buttons, obviously also can adopt other connected modes, as be threaded etc.; Projection 7 sidelines on spool 3 surfaces are five edge break lines.
During actual the use,, flow out from the outlet 6 of control valve along the spool 3 and the gap of valve cylinder 4 when polymer solution enters control valve from 5 positions that enter the mouth.At this moment, can drive spool 4 rotations by rotation regulating arm 1, realize spool 3 moving up and down in valve cylinder 4, because spool 3 is identical with valve cylinder 4 taperings, so the moving up and down of spool 3 can change the gap of itself and valve cylinder 4 inwalls, when changing the gap, can control the flow of polymer solution.Because in equal length, increased protruding quantity, the step-down increased frequency, the pressure drop effect is remarkable, so can reduce the control valve height under the situation that guarantees injection rate.
Claims (3)
1. one kind is used to annotate the control valve that gathers pipeline adjusted fluid flow and pressure, mainly by regulating arm (1), sealing device (2), be the spool (3) that certain taper and surface are multistage projection vertically, axially tapering is identical and have valve cylinder (4) composition that inlet (5), bottom have outlet (6) at sidewall with spool (3), wherein regulating arm (1) is pegged graft with sealing device (2), fixedlys connected with spool (3) upper end; Sealing device (2) is pegged graft with spool (3) sealing, is sealedly and fixedly connected with valve cylinder (4) upper end; It is characterized in that: the sideline of spool face projection (7) is a broken line.
