gravity, enter the first passage 64 in the rotary valve spool 3 under the effect of pressure, and rotary valve spool 3 is rotated further, make first passage 64 and high pressure admission through hole 55, high pressure goes out vent hole 56 and connects, under the high pressure draught effect, airlifting ball 109 is released this device 104, and enter in the air pipe 107, meanwhile, rotary valve spool 3 second channels 63 make goal through hole 53 and low pressure air vent 57 connect again, make airlifting ball 109 enter again in the second channel 63, like this continuously to air pipe 107 services.Regulate motor speed, can change serve speed.Airlifting ball 109 is for being drilled with the hollow nylon ball of an ommatidium.As shown in Figure 7, this device 104 is served a ball in air pipe 107 by certain serve speed, in air pipe 107, form the single fluidal texture of gas column and airlifting ball like this, flow to the concourse of three pipes of lift tube 108, tail pipe 116, air pipe 107 when airlifting ball 109, airlifting ball 109 and the oil that comes from tail pipe, gas is mixed into lift tube 108, in lift tube 108, form airlifting ball 109 on one section gas column, the single slug fluidal texture of airlifting ball 109 the preceding paragraph oils column has so just improved gas lift efficiency.What need here to remark additionally is, in order to prevent send tracheal connector, lift tube joint to be made for an integral body by 180 ° of elbows, have communication port on this elbow at three remittances place card ball, and the communication port on tail tube joint and the elbow is connected, and the bore of communication port is less than the diameter of airlifting ball.Airlifting ball is difficult at three remittances place card ball like this.Oil in the lift tube 108, gas, ball mixture enter in the helical tube with holes 15 in this device 104, because the bleed decelerating effect of aperture on the helix tube 15 makes airlifting ball 109 isolate reposefully and drop on the filter screen 9 and reuse.And oil, gas effect circular motion at centrifugal force, under the effect of Gravity Separation and gas-liquid separation umbrella 17 absorption droplets are opened Oil-gas Separation, and gas is told and come out to recycle pipe through gas from low pressure gas outlet 20 and send high-pressure air source 101 back to and reuse.Oil separates out the back and comes out to measuring station from oil outlet 50.
Can adopt the fuel-displaced device of automatic control of ball float, title holder, lever in this device 104.As shown in Figure 1, below described filter screen 9, be provided with ball float 22, and delivery valve 32 is housed at described oil outlet 50 places, outside the housing 35 of described eliminator, be provided with lever, claim rest device, this lever, claim that rest device is by cross tube 24, middle montant 25, sheer pole 26, adjustable weight 31 is formed, described cross tube 24, middle montant 25, sheer pole 26 is by two minor axises 28,29 according to said sequence tail head, hinged end to end, described cross tube 24 is contained on the buoyage 23 by cross tube axle 27, its front end stretches in the housing 35 of described eliminator, and join with described ball float 22, the middle part of described sheer pole 26 is contained on the described delivery valve 32 by the sheer pole axle 30 on it, described adjustable weight 31 hangs on its afterbody, when high oily of certain liquid level arranged in the housing 35 of this device, ball float 22 moved both vertically up and down with oil level owing to be subjected to the buoyancy of oil.When liquid level is too high, ball float 22 moves upward, and drive cross tube 24 around 27 rotations of cross tube axle, cross tube 24 drives sheer pole 26 by middle montant 25 and rotates, sheer pole 26 drives the sheer pole axle 30 that is located on the sheer pole 26 again changes an angle counterclockwise, the bar of fixedlying connected with this that sheer pole axle 30 drives in the delivery valve 32 rotates counterclockwise, the taper valve core that the end of this bar drives delivery valve 32 moves up, delivery valve 32 apertures are strengthened, to a large amount of oil transportations of measuring station, oil level in the housing 35 is reduced, thereby oil level is stabilized in the safe range.Otherwise housing 35 inner fluid faces are low excessively, and this moment, ball float 22 moved downward, and delivery valve 32 apertures are reduced.The effect of 22 pairs of delivery valves 32 of effect and ball float of 31 pairs of delivery valves 32 of adjustable weight is opposite, is used for the deficiency of 22 pairs of oil level controls of Compensation Regulation ball float.
As shown in Figure 1, the dress oily radiator coil tube 33 of heating in the housing 35 of this device.On housing 35, have and pick up ball mouth 12, ball-loading hole 13, and be furnished with seal cover respectively.Security header 19, safety valve 21, pressure meter 18 are housed on housing 35.Be connected to blow-off pipe 36 in housing 35 bottoms, blowoff valve 37 is housed on it.The housing 35 of this device is installed on the base 34.
Embodiment 2.This is a kind of airlifting ball gas-lift production ball control device that adopts the side valve type sphere-lok.
As Fig. 2, shown in Figure 6, it is different that this employing side valve type airlifting ball gas-lift production ball control device removes sphere-lok, shift fork and embodiment 1, and all the other all are identical.Outside housing 35, be provided with and adjust motor gear reducing gear 1, and there is the drive of the crank of a crank connecting rod sliding block mechanism 82 and this buncher gear reduction 1 hinged, the pull bar 83 of this crank connecting rod sliding block mechanism 82 extend in the housing 35 by the pull rod seal device 81 on the clean-out plate 10 that is contained in housing 35, connect the spool 84 of side valve type sphere-lok in housing 35 on this pull bar 83, shift fork 86 also is contained on this pull bar 83 by small rod.Filter screen 9 is an inclined plane, the side valve type sphere-lok is below the inclined plane of filter screen 9, the horizontal upper table of its guiding valve valve body 85 and the inclined plane of filter screen 9 link together, the goal through hole 95 of guiding valve valve body 85 is vertical with the upper surface of guiding valve valve body 85, as shown in Figure 6, perforate 70 for pull bar 83 motions is arranged on the slideway of guiding valve gliding mass 85, and balance pipe 71.Guiding valve valve body 85 has four through holes, goal through hole 95, low pressure air vent 96; High pressure admission through hole 97, high pressure go out vent hole 98, and two passes is arranged on the valve core of the spool valve 84: first passage 91, second channel 92.Driving valve core of the spool valve 84 by pull bar 83 slides in guiding valve valve body 85, when valve core of the spool valve 84 outer spacing on the time, second channel 92 is connected goal through hole 95 and low pressure air vent 96, makes that the airlifting ball 109 in goal through hole 95 enters in the second channel 92; When valve core of the spool valve 84 slided into inner spacing going up, second channel 92 goes out vent hole 98 with high pressure admission through hole 97, high pressure to be connected, and from the high pressure draught of high-pressure pipe 7 airlifting ball 109 is brought into the high pressure escape pipe 8, and is entered in the air pipe of oil well.Simultaneously, first passage 91 is connected goal through hole 95, low pressure air vent 96, and airlifting ball can enter in the goal through hole 95 under the stirring of shift fork 86, and pull bar 83 drive guiding valve slide cores are slided repeatedly like this, constantly to the air pipe service of supplying gas.The mechanism of other among the embodiment 2 all is identical with embodiment 1, so no longer describe.The variable-speed motor gear reduction all is identical among embodiment 1 and the embodiment 2, can buy on the market.
