Description
Technical field
The present invention relates to petroleum technology fields, and in particular to a kind of oil field shaft mouth oil spout closure cell structure.
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 oil field shaft mouth oil spouts to block cell structure.
To achieve the above objectives, 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 cock body for blocking cavity, blocks and is provided with positioning baffle at the top of room, and one end of cock body is contacted with positioning baffle, other end connection
There is spring, spring-compressed is between closure room side wall and cock body.
End cap is installed on the wedge block.
The wedge block is inverted trapezoidal structure.
The motor for driving positioning baffle to move upwards is provided on the positioning baffle.
Compared with the prior art, the invention has the benefit that
The invention discloses a kind of oil field shaft mouth oil spouts to block cell structure, blocks room by setting and for blocking cavity
Cock body cock body is blocked by positioning baffle in inoperative, when leakage, by pulling out positioning baffle, cock body is in spring
Promotion under, ensure that under sufficient pressure enter cavity, obstruct circuit, prevent the defeated manifold of oil gas sum aggregate in oil well to flow back into
Gas mixture will go out from well head jet flow, avoid the wasting of resources and large area environmental pollution, and component pole of the invention
Easily buying reduces the cost without especially processing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that oil field shaft mouth oil spout of the present invention blocks cell structure.
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 oil field shaft mouth oil spouts to block cell structure, including the light being set in oil well
Bar 1, the outside of polished rod 1 are provided with shell 2, and the top of shell 2 is equipped with the wedge block 3 for fastening polished rod 1, is arranged on shell 2
There is cavity 6, position corresponding with cavity 6, which is provided with, blocks room 4, the cock body being equipped in room 4 for blocking cavity 6 is blocked,
The top for blocking room 4 is provided with positioning baffle 5, and one end of cock body is contacted with positioning baffle 5, and the other end is connected with spring 7, spring
7 are compressed between closure 4 side wall of room and cock body.
The wedge block 3 is fixedly connected on the upper end outer surface of polished rod 1；End cap 8, the end cap 8 are installed on wedge block 3
It is fixedly connected on the upper surface of shell 2；The wedge block 3 is inverted trapezoidal structure.
Further, the motor for driving positioning baffle 5 to move upwards is provided on the positioning baffle 5.
The course of work of the invention are as follows:
In inoperative, cock body is blocked by positioning baffle 5, when leakage, by pulling out positioning baffle 5, cock body exists
Enter cavity 6 under the promotion of spring 7, obstructs circuit, prevent the gas mixture that the defeated manifold of oil gas sum aggregate flows back into oil well
It will go out from well head jet flow, and avoid the wasting of resources 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.
