Control system is provided with the detection module (not shown) that the air pressure to inlet channel 113 and outlet passageway 112 is detected.
When using gas well remote high-voltage switch well device of the present utility model to be driven a well, at first, control system is given the first Electrical heads 5 energisings, the magnetic core retraction of this first Electrical heads 5, magnetic core bottom end seal face is opened, and first and the second portion of the first discharge channel 12 of switch valve 1 are connected.Now, the valve core housing epicoele 171 of switch valve 1 is connected with ambient atmosphere, and the pressure in valve core housing epicoele 171 reduces rapidly.The valve core housing 17 of switch valve 1 stationary magazine creel 131 along switch valve 1 under the effect of the elastic-restoring force of the first elastic component 2 moves on the direction of valve gap 13, thus open switch valve 1 spool 15 clearance groove 155 and clearance groove 155 and the inlet channel 113 of switch valve 1 are connected.High-pressure natural gas in gas well enters reducing valve 3 air inlet port 353 by clearance groove 115 flows out by gas outlet 355.Like this, reducing valve 3 is started working, and after the high-pressure natural gas in inlet channel 113 continue to be depressurized valve 3 and are kept to low pressure, through gas outlet, 355 outlet passageways by switch valve 1 112 flow out, and have avoided can not realizing the function that automatically drives a well under high pressure.
Then, after after a while, due to adopted Downhole Choking Technology (such as, Soviet Union's Sulige gas field gas well adopts Downhole Choking Technology, because the reason of production technology in Soviet Union's Sulige gas field Wellbore of Gas Wells),, the gas pressure in the inlet channel 113 of gas well remote high-voltage switch well device of the present utility model can reduce automatically.When the detection module of control system detects gas pressure in inlet channel 113 and is reduced to the pressure approached in outlet passageway 112, control system is given the second Electrical heads 7 energisings, the magnetic core retraction of the second Electrical heads 7, magnetic core bottom end seal face is opened, and first and the second portion of the second discharge channel 14 of switch valve 1 are connected.Now, the spool epicoele 313 of switch valve 1 is connected with ambient atmosphere, pressure in spool epicoele 313 reduces rapidly, the pressure reduction of the bottom surface of the end face of the first end of the reducing valve body 31 of reducing valve 3 and the brace table 151 of spool 15 promotes spool 15, valve core housing 17 and reducing valve 3 integral body and moves on the direction of valve gap 13, thereby inlet channel 113 is communicated with outlet passageway 112, gas well is opened fully, has avoided because spool 15 opening degrees are little, and sealing contact surface easily amasss sand and causes the problem of leaking in electromagnetic valve.And, in this process, the first elastic component 2 and the second elastic component 4 are compressed.
Finally, when needs are closed gas well, control system is given the first Electrical heads 5, the second Electrical heads 7 outages, thereby makes first and the second portion blocking-up of the first discharge channel 12; The first of the second discharge channel 14 and second portion blocking-up.And simultaneously, control system is given the 3rd Electrical heads 9 energisings, the magnetic core retraction of the 3rd Electrical heads 9, magnetic core bottom end seal face is opened, the first of the pressurising passage 16 of switch valve 1 and second portion are connected, high-pressure natural gas in inlet channel 113 flows into respectively in valve core housing epicoele 171 and spool epicoele 313 by pressurising passage 16, thereby the pressure in valve core housing epicoele 171 and spool epicoele 313 is increased.Under the effect of the elastic-restoring force of the pressure differential between valve core housing epicoele 171, spool epicoele 313 and outlet passageway 112, gravity and the first elastic component 2 and the second elastic component 4, spool 15, valve core housing 17 and reducing valve 3 all fall to the direction away from valve gap 13.Now, the bottom surface contact of the brace table 151 of spool 15 is on the support flange collar 191 of valve seat 19, and outlet passageway 112 is closed.At this moment, high-pressure natural gas continues to flow in valve core housing epicoele 171 and spool epicoele 313 by pressurising passage 16, makes the pressure flowed in valve core housing epicoele 171 and spool epicoele 313 more and more high, thereby, what spool 15 was pressed down is tighter, and it is tighter that outlet passageway 112 is also just closed.
From above-mentioned narration: gas well remote high-voltage switch well device of the present utility model is successively by the first Electrical heads 5, the second Electrical heads 7 valve core housing 17 and spool 15 of lifting switch valves 1 respectively, and by built-in reducing valve 3 decompressions, can realize gas well remote high-voltage switch well, solution must not remote high-voltage switch well a difficult problem, reduce gas well management maintenance difficulty, reduce manpower and materials consumption, guarantee the production run safety and steady.And gas well remote high-voltage switch well device of the present utility model control to the first Electrical heads 5, the second Electrical heads 7 and the 3rd Electrical heads 9 by control system, realize automation remote gauge tap gas well, reduced manpower and materials, reduced cost.In addition, carry out the motion of control valve core retainer plate 17 and spool 15 by the break-make of the first Electrical heads 5 and the second Electrical heads 7, to switch valve 1, in high pressure or low pressure motion, provide automatic protection, improved automatization level, have broad application prospects in the gas-field exploitation field.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
