It is threaded connection with packing box upper cover and forms, sealing gasket at least two groups, it is provided with dividing plate between every two groups of sealing gaskets, goes up most
The upside of the one group of sealing gasket in face is provided with pressing plate, described packing box covers and has been threaded connection blowout prevention box, blowout prevention box bag
Include blowout prevention box housing and blowout prevention box upper cover, blowout prevention box housing and blowout prevention box upper cover to be threaded connection, the central authorities of blowout prevention box upper cover
Being provided with for the circular hole through polished rod, the downside of blowout prevention box upper cover is hinged with baffle plate, and after light rod-broken, baffle plate is at back-moving spring
Driving under be flipped up, then described circular hole is blocked to realize blowout prevention function.
The outside at the two ends up and down of described often group sealing gasket is cone structure, the both sides of described dividing plate and pressing plate
Side is provided with the groove coordinated with described cone structure.Described often group sealing gasket is by least three gasket seal group
Becoming, gasket seal is divided into cushion film and hard packing sheet two kinds, and two kinds of pads are alternately arranged.The side of described blowout prevention box housing connects
There is oil exit pipe, oil exit pipe is provided with draining valve.The described inner side bottom circular hole is provided with rubber bodies, and rubber bodies directly vulcanizes
Covering on blowout prevention box, the side that described baffle plate contacts with polished rod is provided with roller.The lower end of described packing box housing
It is provided with the ring flange for this device being arranged on well head.
The beneficial effects of the utility model are: use this utility model, when sealing gasket may wear to a certain degree, by rotation
Turn blowout prevention box housing can compression seal pad further, make sealing gasket gather to compensate wear extent to polished rod, and then improve and seal
The service life of pad；The setting of the cone structure on sealing gasket, dividing plate and pressing plate so that encapsulant can be more effectively to light
Bar is gathered, and further ensures sealing effectiveness；Two kinds of gasket seals of soft or hard are used to be combined into sealing gasket so that sealing gasket during compression
The deformation quantity of each layer evenly, further ensures sealing.The setting of blowout prevention box, can be when light rod-broken, by this device
The circular hole closure of upper end, prevents crude oil leakage from polluting environment, and the crude oil that can be will leak out by draining valve is guided in container, prevents
During maintenance, crude oil sprays again, pollutes well site.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-cushion film, 2-hard packing sheet, 3-dividing plate, 4-packing box housing, 5-packing box upper cover, 6-blowout prevention box housing,
7-polished rod, 8-roller, 9-blowout prevention box upper cover, 10-rubber bodies, 11-baffle plate, 12-draining valve, 13-pressing plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
The present embodiment includes packing box and sealing gasket, and sealing gasket is arranged in packing box, and packing box is by packing box housing 4 He
Packing box upper cover 5 is threaded connection and forms.Sealing gasket at least two groups, is provided with dividing plate 3 between every two groups of sealing gaskets, goes up most
The upside of the one group of sealing gasket in face is provided with pressing plate 13.The designs organizing sealing gasket so that can have according to abrasion condition during maintenance more
Certain group sealing gasket of selective replacing, and need not all change, thus reduce maintenance cost.
