Abstract
The utility model relates to a multifunctional pumping rod seal used on a special oil field device of a well mouth pumping unit. Two sealing rubber blocks are mounted in the left and right sides of the main body separately; a sealing rubber ball is mounted on the upside of the main body; and a helical reverse taper sealing body is mounted in the upper chamber of the upper sealing cover, which is connected with a compression nut to realize the three times of sealing on the pumping rod, extend the service life of the machine and extend the sealing element replacing period from one month to half a year each time so as to increase the output of the pumping unit obviously. Additionally, to prevent the blowout, disassemble the compression nut on the upper sealing cover and install and connect a blowout preventer. If the pumping rod is broken, the oil pressure underground will force the hollow blowout preventing ball in the blowout preventer to move to the top of the chamber and plug up the oil outlet so as to prevent the oil from blowing out of the well.
Description
Technical field
The utility model is the employed multifunctional pumping rod sealer of a kind of oil field special equipment well head oil pumper.
Background technology
There is following shortcoming in existing sucker rod sealing device: 1, weight has the 15-20 kilogram at least, and loading and unloading are inconvenient; 2, its structure mostly is the platen radical, and trouble is changed in filler wearing and tearing back, and can only change than the upper strata.And more following scratch not come out.3, packing is a consumable accessory, and 3-5 day must be changed once; Each packing of changing must be shut down 20-30 minute, thereby influences its output.
Summary of the invention
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of multifunctional pumping rod sealer of good sealing effect is provided.
The utility model is achieved in that to cooperate with the tuningout base of bottom installs the tuningout ball, between tuningout base and the tuningout ball sealing ring is installed, big hoop is connected with the tuningout base, after the tuningout pad is installed in tuningout spheroid upper end main body is installed, about main body is interior the once sealing blob of viscose is installed all, inferior sealed gluing block connects slide block by screw, slide block is connected with the adjusting leading screw, regulate the leading screw outside plug is installed, regulate sealing is installed between leading screw and the plug, regulate the leading screw end by the fixing handwheel that rotates of nut.The slide block alignment pin location that slide block is installed by main body.Between main body and the plug sealing mat is installed; The sealing glueballs is installed on main body top, and the sealed upper end lid is installed then, and the upper cavity of sealed upper end lid is installed spiral back taper seal, and the sealed upper end lid connects clamp nut, and the interior tooth of clamp nut is pressed in the end of spiral back taper seal.In addition,, pull down the clamp nut at sealed upper end lid place, the connection preventer is installed for preventing blowout.
Advantage of the present utility model is, about main body is interior the once sealing blob of viscose is installed all, and the sealing glueballs is installed on main body top, and the sealed upper end lid is installed then, the upper cavity installation spiral back taper seal of sealed upper end lid, and the sealed upper end lid connects clamp nut; Thereby realize three sealings to sucker rod.Because sucker rod is in operation, pressure at following oil reservoir upwards produces oil pressure, oil can be taken out of with sucker rod, and upper end cover can make the locking amount of sealing glueballs compression 10mm, locking gradually, make sealing glueballs and spiral back taper seal form radial pressure naturally and hold sucker rod tightly, thereby therefore reach sealing function at this well head place and internal diameter pressurized.Especially the helixseal structure that had of spiral back taper seal when installing and using, makes sealing effectiveness better, has prolonged the application life of complete machine; Once change seal by every month, it is above just with the replacing seal to reach half a year, thereby has significantly improved the output of oil pumper.In addition,, pull down the clamp nut at sealed upper end lid place, the connection preventer is installed for preventing blowout.When rod snap occurring, down-hole oil pressure can make the interior hollow spray-proof ball of preventer move on to the cavity top and block oil-out, is blowout thereby stoped oil outwards to spray.

The specific embodiment
Describe in detail below in conjunction with accompanying drawing:
As shown in the figure, cooperate installation tuningout spheroid 12 with the tuningout base 15 of bottom, sealing ring 13 is installed, big hoop 14 is connected with tuningout base 15, main body 5 is installed after the tuningout pad is installed in tuningout spheroid 12 upper ends, about in the main body 5 once sealing blob of viscose 6 is installed all, once sealing blob of viscose 6 connects slide block 8 by screw 7, slide block 8 is connected with adjusting leading screw 9, regulate leading screw 9 outsides plug 10 is installed, regulate sealing is installed between leading screw 9 and the plug 10, the end of regulating leading screw 9 is by the fixing handwheel 11 that rotates of screw, the slide block alignment pin location that slide block 8 is installed by main body.Between main body 5 and the plug 10 sealing mat is installed; Main body 5 top inner chambers are installed sealing glueballs 4, and sealed upper end lid 3 is installed then, and spiral back taper seal 2 is installed in the upper cavity of sealed upper end lid 3, and sealed upper end lid 3 connects clamp nut 1, and the interior tooth of clamp nut 1 is pressed in the end of spiral back taper seal 2.In addition,, pull down the clamp nut 1 at sealed upper end lid place, connection preventer 16 is installed for preventing blowout.
