Abstract
The invention discloses a kind of anti-top spray devices of oil well, including the polished rod being set in oil well, shell is provided on the outside of polished rod, the top of shell is equipped with the wedge block for fastening polished rod, cavity is provided on shell, position corresponding with cavity, which is provided with, blocks room, block the sphere being equipped in room for blocking cavity, block the baffle being equipped in room for stopping sphere to slide, steel ball is blocked by baffle, when leakage, by pulling out baffle, steel ball enters cavity, obstruct circuit, prevent the gas mixture that the defeated manifold of oil gas sum aggregate flows back into oil well that will go out from well head jet flow, avoid the wasting of resources and large area environmental pollution.
Description
Technical field
The present invention relates to petroleum technology fields, and in particular to a kind of anti-top spray device of oil well.
Background technique
Petroleum is the main energy sources resource of modern industry, is a hiding entity, in recovery process under the burial ground of oil field
In, interior oil, gas and water are constantly flowed, are vary, and this rheological characteristic is the spy that other solid mineral reserve do not have
Point.Currently, in having bar oil recovery process, it some times happens that the polished rod fracture accident at the top of sucker rod.Pumping unit installation foundation compared with
Low, polished rod eye clamping plate bottom is big compared with small and dead space with a distance from packing box, and polished rod broken end will fall into packing box hereinafter, deep-well pump plunger shaft
Plug is sat extremely in pump barrel, and oil well stops production and well head is in runaway condition, and the defeated manifold of oil gas sum aggregate flows back into a large amount of oil well
Gas mixture will come out from well head jet flow, cause vast resources waste and large area environmental pollution, cause certain loss.
Summary of the invention
In view of the foregoing drawbacks or insufficient, the purpose of the present invention is to provide a kind of anti-top spray devices of oil well.For up to
To object above, the technical solution of the present invention is as follows:
Including the polished rod being set in oil well, shell is provided on the outside of polished rod, the top of shell is equipped with polished rod is tight
Solid wedge block, be provided with cavity on shell, position corresponding with cavity, which is provided with, blocks room, blocks to be equipped in room and is used for
The sphere of cavity is blocked, the baffle being equipped in room for stopping sphere to slide is blocked.
The bottom end for blocking room is provided with sliding slot.
The motor for driving baffle to move upwards is provided on the baffle.
The sphere is sphere made of steel or building stones.
Compared with the prior art, the invention has the benefit that
The present invention provides a kind of anti-top spray devices of oil well, block room by setting and the sphere for blocking cavity,
In inoperative, steel ball is blocked by baffle, when leakage, by pulling out baffle, steel ball enters cavity, obstructs circuit, resistance
Having stopped the gas mixture that the defeated manifold of oil gas sum aggregate flows back into oil well will go out from well head jet flow, avoid the wasting of resources and big face
Product environmental pollution, and component of the invention is easily purchased, and without especially processing, is reduced the cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the anti-top spray device of oil well of the present invention.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of anti-top spray devices of oil well, including the polished rod 1 being set in oil well, polished rod
1 outside is provided with shell 2, and the top of shell 2 is equipped with the wedge block 3 for fastening polished rod 1, is provided with cavity 6 on shell 2,
Position corresponding with cavity 6, which is provided with, blocks room 4, blocks the sphere being equipped in room 4 for blocking cavity 6, blocks in room 4
Baffle 5 for stopping sphere to slide is installed, the bottom end for blocking room 4 is provided with sliding slot, in addition, described in the present invention
It is provided with the motor for driving baffle to move upwards on baffle 5, facilitates the promotion of baffle.In the present invention, the wedge block 3 is in
Inverted ladder shape.
In order to enable blockage effect is obvious, the sphere is sphere made of steel or building stones.
The course of work of the invention are as follows:
In inoperative, steel ball is lived by baffle gear 5, when leakage, by pulling out baffle 5, steel ball enters cavity 6,
Circuit is obstructed, prevents the gas mixture that the defeated manifold of oil gas sum aggregate flows back into oil well that will go out from well head jet flow, avoids money
Source waste and large area environmental pollution.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
