Abstract
The utility model relates to a flow adjusting valve for a water injection well of an oil well, and belongs to a valve. A valve core (14) positioned on the center of a valve body (2) is provided with two flow holes (15) with unequal hole diameters in the radical direction of the circumference. A sealing cushion ring (5) is arranged between the valve body (2) and the valve core (14). The utility model has the advantages that the structure is simple, the flow can be directly adjusted under the condition of no stop of the water injection well, and the test time is greatly shortened.
Description
Technical field
The utility model belongs to valve, relates to a kind of water injection well in oil fields flow control valve.
Background technology
Water injection well has played important role in Oilfield developing, and the demonstration of water injection well suction indicative curve, has demonstrated fully the water absorbing capacity of water injection well, need regulate the flow of water injection well when measuring the suction indicative curve.Traditional Flow-rate adjustment mode is for regulating by the water nozzle (aperture of water nozzle commonly used is respectively 4cm, 6cm, 8cm, 10cm, 12cm) of changing different apertures.Water nozzle of every replacing just need stop water injecting pump once, and test operation is more loaded down with trivial details, and workload is big, and holding time is many, and efficient is low.
Goal of the invention
The purpose of this utility model is exactly to overcome above-mentioned deficiency and a kind of water nozzle that does not need to change different apertures is provided, can continuous operation and regulate the control valve of different flow.
The solution that realizes the utility model purpose is to comprise valve body (2), water inlet (1), delivery port (3), spool (14), gland (8), handle (10), the circumference that particularly is positioned at the spool (14) at valve body (2) center radially has the metering orifice (15) that does not wait at least two apertures, is provided with seal washer (5) between valve body (2) and the spool (14).
Valve body (2) locates to be provided with pressure detecting mouth (4) near delivery port (3).The profile of spool (14) is cylinder or spheroid.
The utility model has the advantages that compact conformation, can under the situation of not stopping water injection well, directly regulate flow, shortened the testing time greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right sectional view of Fig. 1.
Fig. 3 is that spool of the present utility model is the structural representation of spheroid.
The right sectional view of Fig. 4 Fig. 3.
Among the figure: the 1st, water inlet, the 2nd, valve body, the 3rd, delivery port, the 4th, pressure detecting mouth, the 5th, seal washer, the 6th, packing ring, the 7th, pressure relief opening, the 8th, gland, the 9th, oil filler, the 10th, handle, the 11st, bearing, the 12nd, gland bolt, the 13rd, bearing, the 14th, spool, the 15th, metering orifice, the 16th, valve core rod.
The specific embodiment
Be provided with spool 14 at the center of valve body 2, spool 14 is cylinder or spheroids of a center cavity, sealing of the cylinder of center cavity or spheroid is connected with valve core rod 16, the other end cavity communicates with delivery port 3 on the valve body 2, circumference at spool 14 radially has several metering orifices 15 that does not wait in the aperture, metering orifice 15 is communicated with the surface of cavitys and cylinder or spheroid, and metering orifice 15 communicates with water inlet 1 on the valve body 2.Be provided with seal washer 5 and pad 6 between valve body 2 and the spool 14.If spool 14 is cylinders, pad 6 is positioned at the centre of seal washer 5, and seal washer 5 perhaps all is that seal washer 5 is not established pad 6 in the both sides of pad 6, if spool 14 is that spheroid has groove at valve body 2 or on gland 8, is placed with seal washer 5 in the groove.Be connected with gland 8 by bearing 11, bearing 13 on valve core rod 16, gland 8 is connected by gland bolt 12 and valve body 2 again, and the termination of valve core rod 16 is connected with handle 10, is provided with the oil filler 9 of apply oil on gland 8.On valve body 2, go out to be provided with pressure detecting mouth 4 near delivery port 3.On gland 8, be provided with pressure relief opening 7.
Press water enters from water inlet 1 during work, enters the cavity of spool 14 by the metering orifice on the spool 14 15, flows to delivery port 3 by cavity again.Can record hydraulic pressure by pressure detecting mouth 4.Rotary handle 10, spool 14 also together rotate, metering orifice 15 that can the different apertures of conversion, thus record the pressure of different flow.
Claims (3)
1, a kind of water injection well in oil fields flow control valve, comprise valve body (2), water inlet (1), delivery port (3), spool (14), gland (8), handle (10), the circumference that it is characterized in that being positioned at the spool (14) at valve body (2) center radially has the metering orifice (15) that does not wait at least two apertures, is provided with seal washer (5) between valve body (2) and the spool (14).
2,, it is characterized in that said valve body (2) locates to be provided with pressure detecting mouth (4) near delivery port (3) according to the said water injection well in oil fields flow control valve of claim 1.
3, according to the said water injection well in oil fields flow control valve of claim 1, the profile that it is characterized in that said spool (14) is cylinder or spheroid.
