Abstract
The utility model relates to an inclined-face type flow control valve which mainly solves the problems that the existing control valve often has unstable water-controlling amount even injection stopping phenomenon during work and normal production is influenced. The inclined-face type flow control valve is characterized in that a ladder shaft shape valve core (1) is internally arranged in a ladder hole of a valve body (4); a lower section shaft (7) of the valve core (1) is in an inclined-face body; an upper section shaft of the valve core (1) passes through a centre hole of a valve cap (2) to be connected with screw threads of the valve cap; and the side wall of the valve body (4) is provided with a water outlet hole (8) communicated with a water outlet pipe (9). The water-injection amount of the valve is stable, the utility model can not have injection stopping phenomenon when being arranged on any water-injection well, the structure is simple, the operation is safe and convenient, and the manufacture cost is low.
Description
Technical field
The utility model relates to a kind of water injection well in oil fields flow control valve, relates to a kind of ramp type flow control valve specifically.
Background technology
The water control valve of water injection well use at present is various high pressure large aperture stop valve, the bad control of the water yield in use, the more difficult debugging of the well that particularly injection allocation amount is low, the water yield is suddenly big or suddenly small wayward, also stops the phenomenon annotated sometimes, has a strong impact on the normal operation of water injection well
The utility model content
In order to make control valve energy operate as normal, guarantee that little water injection rate well normally steadily carries out water filling, the utility model provides a kind of ramp type flow control valve.This valve arrangement is simple, and is easy to operate, and water filling operates steadily in the use, and can avoid occurring stopping annotating phenomenon.
The technical solution of the utility model is: a kind of ramp type flow control valve, valve body, spool and the bonnet in axial step hole are arranged in comprising, and the shoulder hole of valve body is built-in with multidiameter type spool, and spool hypomere axle is clinohedral; The epimere axle of spool passes the bonnet centre bore and is threaded with it; There is weep hole to communicate on the sidewall of valve body with outlet pipe.
Fixed valve base and its endoporus cooperate with the axle that is clinohedral in the described valve body shoulder hole; Valve seat is threaded with valve body; Valve seat has on step and its some holes of pulling is arranged; Bonnet is threaded with valve body and the junction is equipped with sealing ring; Spool and bonnet cooperation place are equipped with sealing ring.
The beneficial effects of the utility model are: because this ramp type water control valve adopts above technical scheme, inclined-plane by the spool lower end axially cooperates with valve seat orifice, regulate the water space of crossing with valve base chamber by moving axially of spool, reach the effect of control flow, there be not the situation of flow with pump surge, thereby make water injection rate steady, water injection well normally moves.
Description of drawings
Accompanying drawing 1 is this ramp type flow control valve structural representation;
Accompanying drawing 2 is the structural representation of sequence number 5 valve seats in the accompanying drawing 1;
Accompanying drawing 3 for accompanying drawing 1 in the spanner result schematic diagram that is used of sequence number 1-spool;
Accompanying drawing 4 for accompanying drawing 1 in the spanner result schematic diagram of sequence number 5-valve seat-be used.
Real-time mode
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing 1 and accompanying drawing 3, this ramp type flow control valve comprises: valve body 4 cylindraceous, the reducing hole is arranged in the valve body 4, and the valve body 4 upper ends bonnet 2 that is threaded, and the external diameter of bonnet 2 is identical with the external diameter of valve body 4, is equipped with sealing ring 3 at connection of thread; There is inlet opening 6 valve body 4 lower ends, and the aperture internal thread on 6 tops, inlet opening is installed valve seat 5, have through hole that step is arranged outward on the valve seat 5, and are sitting on the interior shaft shoulder of valve body 4 small-bores, have weep hole 8 to communicate with outlet pipe 9 on the sidewall of valve body 4.Be equipped with spool 1 in the hole of valve body 4, spool 1 also is the axial workpiece of reducing, the cylinder 7 of spool 1 lower end puts in the hole of valve seat 5 and its axially movable cooperation, and cylinder 7 is surface cylinder shape, and the epimere of spool 1 passes the centre bore of bonnet 2 and be threaded with it, upper end at the spool 1 that stretches out bonnet 2 is square, by spanner 13 matching used as shown in Figure 3 with it, card helps square toes and rotary spool 1, adjust the axial location of inclined-plane in valve seat 5 holes of cylinder 7 and promptly adjust the water inlet gap, thereby reach the purpose of adjusting water injection rate; Between the interruption face of cylinder of spool 1 and cylinder that bonnet 2 endoporus cooperate, be equipped with sealing ring 3, prevent to reveal between the cylinder of current by spool 1 and valve body 4.
Shown in accompanying drawing 2 and accompanying drawing 4, some holes 10 of pulling are arranged on the step of valve seat 5, the lower end of valve seat spanner 11 has several to pull post 12 as shown in Figure 4, when changing valve seat 5, with its valve seat spanner 11 put in make in valve body 4 holes that it pulls that post 12 puts in valve seat 5 pull in the hole 10 and rotary valve base spanners 11, can unload lower valve base 5, reverse rotation valve seat spanner 11 gets final product during installation.
When control valve is installed, at first each position sealing ring 3 is installed, spool 1 is passed bonnet 2, bonnet 2 is connected with valve body 4 again, the inlet opening 6 with valve body lower end is connected with waterflood-transmission line then, by spanner 13 rotary spools 1 control injection rate.Through field trial, this control valve control water yield is stable, has reached the requirement of steady water filling, its control water yield scope is at 0.1 cubic metre/hour-12 cubic metres/hour, under identical fracture pressure condition, can increase the water injection rate of individual well, and can install to any water injection well and the phenomenon of stopping annotating can not occur.This valve arrangement is simple, easy-to-operate, and cost is low.
