Envelope in-core wall is circumferentially gone up uniform intervals and four sealing paraffin cutting fins is distributed with, and seals centre bore and oil pumping that paraffin cutting fin is surrounded
Bar interference fit connects.
Height of the height of the sealed core in such scheme more than oil pumping rod centering device.Described sealed core is by three rubber
Circle composition, each rubber ring are divided into pintongs and are clamped by upper and lower two pads, and centre bore and the sucker rod interference of rubber ring are matched somebody with somebody
Close connection, three clamped by upper and lower two pads after rubber ring be bolted in the position at edge and be integrated, adjacent two
There is interval between rubber ring.Described upper press cover threaded upper ends are connected with sealing shroud, and sealing ring is provided with sealing shroud, sealing ring
Gasket ring is provided between lower surface and sealing shroud, sealing ring upper surface has tightening nut to be threadedly coupled with sealing shroud, sealing ring it is upper
Sealing gasket is provided between end face and tightening nut, in sealing ring, has connecting rod to pass through, connecting rod upper end is fixedly connected with handling and connects
Head.
The beneficial effects of the utility model are：This device is prevented suitable for centralizer diameter is bigger than normal with the difference of oil pumping shank diameter
Eccentric wear well, using this utility model, during workover treatment acts sucker rod, as sealed core point pintongs is provided with the sealing of four roads
Protection, centralizer sealed core when passing through will not have damage, and in well, liquid will not be sprayed from well head, it is to avoid crude oil pollution well site,
Alleviate the labor intensity of workman；The wax deposition of sucker rod can be wiped off by sealed core simultaneously in addition, eliminate and pumped with steam clean
Bar operation, stops to pass through handling joint, connecting rod, tightening nut, sealing shroud, sealing gasket, sealing ring and pad during operation between sucker rod
Ring group into hanger, 2 minutes control well head.Labor intensity and production cost greatly reduces.

Specific embodiment
This utility model is described further below in conjunction with accompanying drawing：
As shown in FIG.：Polish rod sealing device includes sealed body 9, and 9 threaded upper ends of sealed body are connected with upper press cover
8,9 lower end of sealed body is threaded with short circuit 12, and short circuit 12 is connected with well head, and 9 bottom of sealed body is communicated with mozzle 11,
Sealed core 10 is provided with sealed body 9, sealed core 10 has sealing function to sucker rod, the sucker rod for is acted through 10 liquid of sealed core
Body will not be sprayed from well head, it is to avoid environmental pollution, and sealed core 10 is uniformly divided into pintongs in the axial direction and combines as cylinder,
It is that, in order to ensure that centralizer can be passed through, because centralizer ratio is pumped, shank diameter is somewhat larger, close that sealed core 10 is divided into pintongs
Envelope core 10 has plastic deformation after being divided into pintongs, uniform intervals are distributed with four sealing paraffin cutting fins to 10 inwall of sealed core vertically
13, the centre bore that sealing paraffin cutting fin 13 is surrounded is connected with sucker rod interference fit.The 13 pairs of oil pumping of each sealing paraffin cutting fin
Bar has sealing function, and the wax deposition on sucker rod can also be wiped off by sealing paraffin cutting fin 13, and the wax wiped off is discharged by mozzle 11.
Sealed core 10 has dual function.
Height of the height of sealed core 10 more than oil pumping rod centering device.When centralizer passes through the top of sealed core 10 or under
Portion it is total some be sealing sucker rod, so when centralizer by when do not interfere with sealed core 10 and seal sucker rod.
In order to be adapted to the demand of different operating modes, sealed core can be made the form of series rubber circle, described sealed core
10 are made up of three rubber rings 14, and each rubber ring 14 is divided into pintongs and is clamped by upper and lower two pads 15, rubber ring 14
Centre bore 16 is connected with sucker rod interference fit, three clamped by upper and lower two pads 15 after rubber ring 14 edge position by
