Description
Technical field:
The invention belongs to a kind of sand discharge pressure release single flow device that oil drilling oil recovery business is used, specifically Rodless oil extraction
Time a kind of sand discharge pressure release single flow device of being used.
Background technology:
The bleeder of the forms etc. such as current the used impacting type of petroleum recovering industry, pressure break formula, is at submersible screw
The installed above of pump case has draining cap, when submersible screw pump quits work, needs the draining in submersible screw pump case
Cap smashes, and after draining cap smashes, the well liquid in oil pipe flows out from this hole, thus protects at submersible screw pump, during each draining
It is all destructive, disposably；Need a down-hole pump and oil pipe all to mention ground before oil recovery and be replaced bleeder.
Summary of the invention:
The purpose of the present invention, in that overcome above-mentioned shortcoming, and provide stable and reliable in work, the economic one used
Sand discharge pressure release single flow device.
Technical scheme to be solved by this invention is: a kind of sand discharge pressure release single flow device, be by lower connecting hoop, housing, on
Housing and upper connecting hoop are formed, and it is characterized in that: installed above at lower connecting hoop has housing, and internally installed at housing has
Piston, is mounted below piston spring at piston, is provided with sealing ring in the outside of piston, and the medium position at housing is processed
There is several oil leak hole, by connecting hoop, upper shell is installed in the position on the top of housing, on upper shell installed above has
Connecting hoop, is provided with fairlead in the position of the inside of upper connecting hoop, and internally installed at fairlead has guide post, at guide post
Outside valve core spring is installed, the location below of guide post is provided with spool.
The present invention is when submersible screw pump duty, and piston moves up under the effect of piston spring and blocks draining
Hole, spool separates with piston under the effect that well liquid rises and is in suspended state simultaneously, and (see Fig. 1) is beneficial to well liquid stream and goes out.
The present invention quits work at submersible screw pump, and when being i.e. in draining duty, (see Fig. 2) spool is at valve core spring
Effect under, spool is closely coupled with the oil outlet of piston upper to be connect, simultaneously piston under powerful well hydraulic coupling together with spool
Moving down simultaneously, now open oil leak hole, the well liquid in oil pipe is flowed out by oil leak hole, thus protects submersible screw pump.
Well liquid of the present invention refers to the mixture liquid of crude oil, water and sand.
The present invention produce good effect: due to sand discharge pressure release single flow device be at submersible screw pump in working order and
Being automatically performed during off position, so being greatly improved work efficiency, and improving the reliability of equipment.
Accompanying drawing illustrates:
Fig. 1 is schematic diagram during submersible screw pump duty of the present invention.(direction of arrow indication is the flowing side of well liquid

Detailed description of the invention:
Embodiments of the invention are described in detail in conjunction with accompanying drawing.
The present invention is just mounted in the oil pump upper end in submersible screw pump, during oil recovery (see Fig. 1) piston at piston spring
Moving up under effect and block oil leak hole, spool is in suspended state with the oil outlet of piston upper simultaneously, is beneficial to well liquid stream
Go out.When being i.e. in draining duty when stopping recovering the oil, (see Fig. 2) spool is under the effect of valve core spring, on spool and piston
The oil outlet in face is closely coupled to be connect, and piston moves down together with spool under powerful well hydraulic coupling simultaneously simultaneously, now opens
Oil leak hole, the well liquid in oil pipe is flowed out by oil leak hole, thus protects submersible screw pump.
The present invention selects the rubber processing of high-quality to make except sealing ring 5, and the effect of sealing is played in its effect exactly, prevents
Well liquid is revealed from oil leak hole, and piston spring 3 and valve core spring 9 all select the spring steel processing and fabricating of high-quality, the work of piston spring 3
Be to ensure that piston 4 housing 2 internal activity freely, when submersible screw pump work under the effect of piston spring 3, make
Piston 4 on move and block oil leak hole 13, the effect of valve core spring 9 be to ensure that guide post 8 fairlead 10 internal activity
Freely.
The present invention remaining parts in addition to sealing ring 5, piston spring 3 and valve core spring 9 all select the steel alloy of high-quality
Processing and fabricating.
The effect of the lower connecting hoop 1 of the present invention is fixing and supports housing 2 and piston spring 3, and the effect of housing 2 is exactly
Installation piston 4 and connecting hoop 7, when the effect of piston 4 is to ensure that submersible screw pump work, piston 4 moves and blocks draining
Hole 13, when submersible screw pump quits work, piston 4 moves down opens oil leak hole 13, it is ensured that well liquid flows out from oil leak hole 13.Connect
Connection upper shell 11 is played in the effect of hoop 7 exactly, and the effect of the effect of upper shell 11 is exactly fixing upper connecting hoop 12, upper connecting hoop
The effect of 12 is exactly fixed guide set 10, and the effect of fairlead 10 is contemplated to install guide post 8, and guarantees that guide post 8 is being led
Up and down being freely provided with spool 6 in the bottom of fairlead 10 in set 10, the effect of spool 6 is exactly to work as submersible screw pump
Play the effect that can seal with piston 4 when quitting work, valve core spring 9 is installed between guide post 8 and spool 6, its effect
It is to ensure that spool 6 can seal reliably with piston 4.
The present invention is the some in submersible screw pump, is mounted in the upper end of suspension connection device.
In sum, the present invention is stable and reliable in work, remarkable in economical benefits, is widely used in oil field employing, CBM Drainage
Draining, well-flushing, sand discharge in water and the work such as remove contamination.
