Abstract
A kind of well blowout preventing formula packing box pressing cap, including：Plug（1）, ball storage barrel（2）, ball sealer（3）, packing box pressing cap（4）；It is characterized in that：The packing box pressing cap of the well blowout preventing formula packing box pressing cap（4）Bottom is provided with internal thread, and top polished rod centerline hole sets a spherical sealed spherical cavity for being more than polished rod hole（Q）Or cylindrical seal spherical cavity（Q'）, in spherical sealed spherical cavity（Q）Or cylindrical seal spherical cavity（Q'）Top set one upper oblique 30。~45。Ball storage barrel（2）, in ball storage barrel（2）Built with ball sealer（3）, in ball storage barrel（2）Upper end provided with plug（1）.The utility model is in light rod-broken, and ball sealer can be slipped to rapidly in sealing spherical cavity, up in the presence of gas stream, seal up polished rod hole, prevent blowout, it is to avoid oil gas energy waste and environmental pollution, it is often more important that prevent fire incident that blowout causes and oil well to scrap accident.
Description
Technical field
The utility model is related to pumping well smooth rod break anti-blowout apparatus, specifically a kind of well blowout preventing formula packing box pressure
Cap.
Background technology
Oilfield pumping well in process of production, makes the center line of horse head suspension point, polished rod and well head not exist due to well head partially
On straight line, cause polished rod axis to distort, produce very big torsional forces, torsional forces is concentrated mainly on polished rod eye and polished rod eye
Between the square clamp in face, under the upper and lower reciprocating load effect of polished rod, polished rod is easiest to break de- here, causes blowout,
Crude oil is caused to waste and environmental pollution.
The content of the invention
The purpose of this utility model is to provide a kind of well blowout preventing formula packing box pressing cap, overcomes lacking for above-mentioned prior art presence
Fall into.
The technical solution of the utility model is achieved in the following ways：
The utility model includes：Plug, ball storage barrel, ball sealer, packing box pressing cap.The well blowout preventing formula packing box pressing cap
Packing box pressing cap bottom is provided with internal thread, and top polished rod centerline hole sets a spherical sealed spherical cavity or cylinder for being more than polished rod hole
Shape seals spherical cavity, is set on the top of spherical sealed spherical cavity or cylindrical seal spherical cavity oblique 30 on one。~45。Ball storage barrel, storage
Ball cylinder is built with ball sealer, in the upper end of ball storage barrel provided with a plug.
Cylindrical seal spherical cavity in above-mentioned well blowout preventing formula packing box pressing cap, it is straight that upper and lower end diameter is less than middle part
Footpath, more than polished rod diameter, be provided with cone seal ball seat in upper end inner circumferential bottom.
Plug in above-mentioned well blowout preventing formula packing box pressing cap is provided with external screw thread, and the top center of plug is blind provided with 3~6 sides
Hole.
The utility model has advantages below：Simple in construction, dependable performance, blowout prevention effect is good；In light rod-broken, sealing
Ball can be slipped to rapidly in sealing spherical cavity, up in the presence of gas stream, seal up polished rod hole, it is therefore prevented that blowout, it is to avoid
Oil gas energy waste and environmental pollution, it is often more important that prevent fire incident that blowout is caused and oil well to scrap accident.
Brief description of the drawings

Fig. 2-the utility model annular seal space is cylindrical structural representation
In figure, 1- plugs, 2- ball storage barrels, 3- ball sealers, 4- packing box pressing caps, 5- polished rods；M- blind holes, Q- spherical sealeds
Spherical cavity, Q'- cylindrical seal spherical cavities.
Embodiment
For further open the technical solution of the utility model, made specifically by embodiment with reference to Figure of description
It is bright：
Well blowout preventing formula packing box pressing cap is made up of plug 1, ball storage barrel 2, ball sealer 3, packing box pressing cap 4.The well blowout preventing
The bottom of packing box pressing cap 4 of formula packing box pressing cap is provided with internal thread, is connected with polished rod sealer, top polished rod centerline hole sets one
The individual spherical sealed spherical cavity Q more than polished rod hole, sets oblique 45 on one on spherical sealed spherical cavity Q top。Ball storage barrel 2, storage
Ball cylinder 2 is built with ball sealer 3, and in the upper end of ball storage barrel 2 provided with a plug 1, the top center of plug 1 is provided with 6 side's blind holes.
When polished rod 5 is disconnected de-, ball sealer 3 can be slipped to rapidly in sealing spherical cavity Q, up in the presence of gas stream, seal up polished rod hole,
Prevent blowout, it is to avoid oil, gas energy waste and environmental pollution, it is often more important that prevent fire incident that blowout is caused and
Oil well scraps accident.
