The present invention will be further described below in conjunction with Figure of description and embodiment.
Description of drawings
Accompanying drawing 1 is the fundamental diagram of corner electric valve.Accompanying drawing 2 is driving and mechanical positioner structure principle charts of corner electric valve.Accompanying drawing 3 is that the corner of corner electric valve opens and closes schematic diagram.
The specific embodiment
Shown two loops in the accompanying drawing 1, one is electric loop, and one is the liquid flow loop.
Wherein the initiating terminal in electric loop and terminal are all on ground remote controllers (11).Ground remote controllers (11) are installed in ground, so be drawn in the top of figure, the positive and negative control power supply of its output is connected on oil pipe (8) and the sleeve pipe (10) by lead, oil pipe (8) extends to power line on the valve body (1) by last end joint (7), has finally passed through the shell of valve pocket (2), reductor (4) and pulse motor (5) power supply has been introduced driver (6).Another utmost point that driver (6) is gone up power supply links to each other with three steel balls (9) with valve body (1) insulation by lead-in wire, and cooperates on the remote controllers (11) of having got back to ground by the close contact with sleeve pipe (10).
The liquid flow loop is: the oily liq in the stratum enters in the annular space between sleeve pipe (10) and the oil pipe (8), because of the top at oil pipe (8) is equipped with packer (18), so oily liq can't return ground by the perforation on the sleeve pipe (10).But when corner electric valve of the present invention was opened, oily liq was pressed the direction shown in the arrow, at first enters sleeve pipe (10) from oil reservoir; Enter in the cavity of spool (3) by valve port (17) on the valve pocket (2) and the valve port (16) on the spool (3) then; The cavity of spool (3) has only a downward passage, and oily liq is pressed the arrow direction earlier downwards, and the oil flow channel along valve pocket (2) makes progress again, enters the cavity of oil pipe (8) through the last end joint (7) of valve body (1); At last, under the effect of oil well pump, extract oily liq out ground, finish whole oil recovery manufacturing process.
