Summary of the invention:
In order to solve existing retracting device structure, installation and complicated operation, the problem of recovering effect difference.The invention provides a kind of environmental protection soiling solution retracting device.This environmental protection soiling solution retracting device has structure, installation and simple to operate, the feature that recovering effect is good.
Technical scheme of the present invention is: this environmental protection soiling solution retracting device comprises main body and lower main body.In upper main body, through hole is connected with source of the gas with switch by joint, pipeline, and lower main body is connected with upper main body by screw thread, and in interior formation cylindrical enclosure chamber; Closed chamber bottom is equipped with conical piston, the guide peg be connected with guide strip is had under piston, on guide peg on guide strip, cover has back-moving spring, the lower main body of corresponding piston both sides laterally slidably connects expansion link, screw thread is had to fix block teeth outside expansion link, screw thread fixes screw thread block teeth exterior arc surface having and matches with oil tubing coupling internal thread, and on the expansion link in lower main body stepped hole, cover has return spring; Airtightly in the annular groove of upper main body and lower main body junction be inlaid with pressure bladder, lower main wall have the air flue road that to be connected with closed chamber with pressure bladder.
Upper main body in such scheme and lower body outer diameter and tubing coupling minor diameter fit gap are 0.15-0.20 millimeter.
The present invention has following beneficial effect: this environmental protection soiling solution retracting device is connected with source of the gas with switch by joint, pipeline owing to adopting through hole in upper main body, and lower main body is connected with upper main body by screw thread, and in interior formation cylindrical enclosure chamber; Closed chamber bottom is equipped with conical piston, the guide peg be connected with guide strip is had under piston, on guide peg on guide strip, cover has back-moving spring, the lower main body of corresponding piston both sides laterally slidably connects expansion link, screw thread is had to fix block teeth outside expansion link, screw thread fixes screw thread block teeth exterior arc surface having and matches with oil tubing coupling internal thread, and on the expansion link in lower main body stepped hole, cover has return spring; Airtightly in the annular groove of upper main body and lower main body junction be inlaid with pressure bladder, lower main wall have optimizing structure of the air flue road that to be connected with closed chamber with pressure bladder, utilize siphon principle, upper carry oil pipe time soiling solution is retained in oil pipe, finally discharge back in sleeve pipe, and then reach simplification structure, convenient installation, simple to operate, the object that recovering effect is good, and simplification operation technique, use and processing cost low, non-maintaining, long-life uses, and improves operating efficiency.This environmental protection soiling solution retracting device has structure, installation and simple to operate thus, the feature that recovering effect is good.
Accompanying drawing illustrates:
Accompanying drawing 1 is this structural representation.
Main body on 1-in figure, main body under 2-, 3-piston, 4-guide strip, 5-guide peg, 6-expansion link, 7-screw thread fixes block teeth, 8-pressure bladder.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in the figure, this environmental protection soiling solution retracting device comprises main body 1 and lower main body 2.There is annular boss outside upper main body 1 upper end, play position-limiting action.Lower main body 2 is connected with upper main body 1 by screw thread, and in interior formation cylindrical enclosure chamber, there is the through hole be connected with closed chamber upper main body 1 upper end, through hole is connected with joint, joint is connected with pipeline, pipeline is in series with switch, pipeline is connected with source of the gas, and upper main body 1 and lower main body 2 external diameter and tubing coupling minor diameter fit gap are 0.15-0.20 millimeter, and fit clearance is large, and sealing effectiveness is poor, upper main body 1 that fit clearance is little and lower main body 2 not easily put into tubing coupling, affect operating efficiency.Closed chamber bottom is equipped with up big and down small conical piston 3, sealing ring is equipped with outside piston 3 upper end contacted with closed chamber, piston has guide peg 53 times, guide peg 5 is placed in the via hole of guide strip 4, guide strip 4 is fixed in closed chamber bottom, on guide peg 5 on guide strip 4, cover has back-moving spring, lower main body 2 wall of corresponding piston 3 both sides laterally slidably connects expansion link 6, screw thread is had to fix block teeth 7 outside expansion link 6, screw thread is fixed on block teeth 7 exterior arc surface the screw thread matched with oil tubing coupling internal thread, on expansion link 6 in lower main body 2 stepped hole, cover has return spring, airtightly in upper main body 1 and the annular groove of lower main body 2 junction be inlaid with pressure bladder 8, lower main body 2 wall have the air flue road that to be connected with closed chamber with pressure bladder 8.
During actual use:
First be connected on derrick by this environmental protection soiling solution retracting device of connection, switch is placed on the derrick of operating personnel's handled easily, is connected by this environmental protection soiling solution retracting device, can normally uses by pipeline with source of the gas.When extracting oil pipe, this environmental protection soiling solution retracting device is placed in tubing coupling, open switch, air pressure promotes piston 3 and moves down, the slope driving expansion link 6 of piston 3, expansion link 6 promotes screw thread and fixes block teeth 7 outwards movement, the screw thread that screw thread is fixed on block teeth 7 blocks mutually with oil tubing coupling internal thread, and then this environmental protection soiling solution retracting device is fixedly connected in tubing coupling, the pressure bladder 8 of air pressure promotion simultaneously outwards expands, oil pipe upper end is sealed up, negative pressure is produced in oil pipe, at this moment oil pipe is carried on, dismantle again and tubing coupling screw thread, soiling solution is removed with oil pipe, again oil pipe lower end is faced toward well head, then closing switch air pressure disappears, pressure bladder 8 collapsed seal disappears, soiling solution flows into backflow down-hole in sleeve pipe, finally descend drain line, again this environmental protection soiling solution retracting device is taken off from upper piece oil pipe, put on lower oil pipe, repeat aforesaid operations, namely recovering effect is realized good, structure, the object of installation and recovery soiling solution simple to operate.
The maximum feature of this environmental protection soiling solution retracting device is that structure is simple, and oil pipe upper end box cupling seals up by this environmental protection soiling solution retracting device, utilizes siphon principle, is reclaimed by the soiling solution in oil pipe, then puts back in well, just reclaimed by soiling solution without other equipment.
