Cap is smashed, and after draining cap is smashed, the well liquid in oil pipe is flowed out from this hole, so as to protect in submersible screw pump, during each draining
All be it is destructive, disposably；Needing a down-hole pump and oil pipe all to mention ground before oil recovery carries out replacing bleeder.
Utility model content：
The purpose of this utility model, in that overcome above-mentioned shortcoming, and provide it is stable and reliable in work, what economy was used
A kind of sand discharge pressure release single flow device.
Technical scheme to be solved in the utility model is：A kind of sand discharge pressure release single flow device, is by lower connecting hoop, shell
What body, upper shell and upper connecting hoop were constituted, it is characterized in that：Housing is installed above lower connecting hoop, in the inside of housing
Piston is installed, piston spring is installed below piston, sealing ring is installed outside piston, at the middle position of housing
Put and be machined with several oil leak holes, upper shell is provided with by connecting hoop in the position on the top of housing, pacify above upper shell
Equipped with upper connecting hoop, fairlead is installed in the position of the inside of upper connecting hoop, guide post is installed in the inside of fairlead,
Valve core spring is installed outside guide post, valve element is installed on the position below guide post.
In submersible screw pump working condition, piston is moved up to block in the presence of piston spring and is let out this utility model
Oilhole, while valve element is separated with piston in suspended state in the presence of well liquid rising, (see Fig. 1) is beneficial to well liquid outflow.
This utility model quits work in submersible screw pump, that is, when being in draining working condition, (see Fig. 2) valve element is in valve element
In the presence of spring, valve element is closely coupled with the oil outlet of piston upper to be connect, at the same piston under powerful well liquid pressure together with
Valve element is moved down simultaneously, now opens oil leak hole, and the well liquid in oil pipe is flowed out by oil leak hole, so as to protect submersible screw
Pump.
Well liquid described in the utility model just refers to the mixture liquid of crude oil, water and sand.
The good effect that this utility model is produced：As sand discharge pressure release single flow device is to be in work shape in submersible screw pump
It is automatically performed when state and off position, so greatly improving work efficiency, and improves the reliability of equipment.
Description of the drawings：
Schematic diagram when Fig. 1 is this utility model submersible screw pump working condition.(direction of arrow indication is the stream of well liquid
Dynamic direction)
Fig. 2 is schematic diagram of this utility model submersible screw pump when quitting work and be in draining working condition.(arrow
The direction of indication is the flow direction of well liquid)
In figure, each label declaration is as follows：
1st, lower connecting hoop, 2, housing, 3, piston spring, 4, piston, 5, sealing ring, 6, valve element, 7, connecting hoop, 8, be oriented to
Bar, 9, valve core spring, 10, fairlead, 11, upper shell, 12, upper connecting hoop, 13, oil leak hole.
Specific embodiment：
Embodiment of the present utility model is described in detail in conjunction with accompanying drawing.
This utility model is just mounted in the oil pump upper end in submersible screw pump, and during oil recovery, (see Fig. 1) piston is in piston bullet
Move up in the presence of spring and block oil leak hole, while valve element is in suspended state with the oil outlet of piston upper, be beneficial to well
Liquid flows out.When being in draining working condition when stopping recovering the oil, (see Fig. 2) valve element in the presence of valve core spring, valve element and work
The oil outlet in face is closely coupled beyond the Great Wall connects, while piston is moved down simultaneously together with valve element under powerful well liquid pressure, now
Oil leak hole is opened, the well liquid in oil pipe is flowed out by oil leak hole, so as to protect submersible screw pump.
Rubber processing of this utility model except sealing ring 5 from high-quality makes, and its effect is exactly to play a part of sealing,
Prevent well liquid from revealing from oil leak hole, the spring steel processing and fabricating of piston spring 3 and valve core spring 9 from high-quality, piston spring 3
Effect be to ensure that piston 4 housing 2 internal activity freely, in submersible screw pump work piston spring 3 effect
Under, be allowed to move on piston 4 and block oil leak hole 13, the effect of valve core spring 9 be to ensure that guide post 8 fairlead 10 inside
Activity is freely.
This utility model conjunction of remaining part from high-quality in addition to sealing ring 5, piston spring 3 and valve core spring 9
Golden steel processing and fabricating.
The effect of lower connecting hoop of the present utility model 1 is to fix and support housing 2 and piston spring 3, and the effect of housing 2 is just
It is, in order to install piston 4 and connecting hoop 7, when the effect of piston 4 is to ensure that submersible screw pump work, to move and block on piston 4
Oil leak hole 13, when submersible screw pump quits work, piston 4 moves down opening oil leak hole 13, it is ensured that well liquid is flowed out from oil leak hole 13.
The effect of connecting hoop 7 is exactly to play connection upper shell 11, and the effect of the effect of upper shell 11 is exactly to fix upper connecting hoop 12, upper company
