Abstract
The utility model relates to an oil machinery, especially an oil drilling preventer. It includes: connecting portion, connecting portion have the chamber of connection and installation cavity, connect chamber and installation cavity and are T style of calligraphy intercommunication, block structure, block structure install in the installation cavity, drive arrangement, drive arrangement install in the installation cavity, and drive arrangement is used for driving the block structure motion will connect the chamber shutoff to connecting the intracavity, wherein, drive arrangement is including base, shutoff head and spring, and the spring supports and establishes between base and shutoff head, and the spring both ends are connected with the electrode, and block structure is ball sealer. The beneficial effects of the utility model are that: structure through the internal diameter that sets up in inside changes has strengthened sealing performance greatly to, using the spring to carry out the driven and reforming transform into the electro -magnet with it simultaneously, the spring becomes the coil during circular telegram, leads to the magnetization of shutoff epicranium, adsorbs ball sealer, makes its and installation cavity inner wall in close contact with, has prevented that the oil from getting into the installation cavity and causing the potential safety hazard.
Description
Technical field
This utility model relates to a kind of field of petroleum machinery, particularly a kind of oil drilling preventer.
Background technology
In the extraction operation of oil, polished rod, due to life-time service, often causes mechanical wear or corrosion fracture suddenly, now it is easy for causing pumpingh well blowout, not only cause the loss of resource property, and owing to environment is caused pollution greatly by the leakage of crude oil, affect normally taking of oil.It is thus desirable to use preventer, and current preventer sealing is poor, and crude oil is easily accessible in installation chamber, and the performance of preventer is produced impact, decreases the service life of preventer.
Utility model content
This utility model is adopted the technical scheme that to solve above-mentioned technical problem:
A kind of oil drilling preventer, comprising: connecting portion, described connecting portion has connection chamber and installation cavity, described connection chamber and described installation cavity are that T font connects；Plugging structure, described plugging structure is arranged in described installation cavity；Driving means, described driving means is arranged in described installation cavity, and described driving means is used for driving described plugging structure to move to described connection intracavity and is blocked in described connection chamber；
Wherein, described driving means includes base, block head and spring, and described spring supports and is located between described base and block head, and the connection of described both ends of the spring has electrode.
Further, described connection chamber connects in primary importance with described installation cavity, and described connection chamber is positioned at above primary importance internal diameter from down to up and tapers into, and is positioned at below primary importance internal diameter from down to up and becomes larger.
Further, described base being provided with iron core, described iron core is positioned at described spring.
Further, described plugging structure is ball sealer.
Further, being provided with catching step in described installation cavity, described catching step becomes larger towards the side internal diameter of primary importance.
Further, the minimum diameter in described connection chamber is less than the diameter of ball sealer.
Further, the minimum diameter of described installation cavity is less than the diameter of ball sealer.
To sum up, the beneficial effects of the utility model are:
The structure of the internal diameter change by arranging in inside, greatly strengthen sealing property, and, spring is used to be transformed into electric magnet while being driven, during energising, spring becomes coil, causes block head to be magnetized, and adsorbs ball sealer, it is made to be in close contact with installation cavity inwall, it is therefore prevented that oil enters installation cavity and causes potential safety hazard.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Wherein, 1-connecting portion, 101-connect chamber, 102-installation cavity, 103-catching step, 2-plugging structure, 3-driving means, 301-base, 302-block head, 303-spring, 304-iron core.
Detailed description of the invention
As it is shown in figure 1, a kind of oil drilling preventer, comprising: connecting portion 1, described connecting portion 1 has connection chamber 101 and installation cavity 102, and described connection chamber 101 connects in T font with described installation cavity 102；Plugging structure, described plugging structure 2 is arranged in described installation cavity 102；Driving means 3, described driving means 3 is arranged in described installation cavity 102, and described driving means 3 is used for driving described plugging structure 2 to be blocked in described connection chamber 101 in moving to described connection chamber 101；Wherein, described driving means 3 includes base 301, block head 302 and spring 303, and described spring 303 supports and is located between described base 301 and block head 302, and the connection of described spring 303 two ends has electrode, and described plugging structure 2 is ball sealer.
Preferably, in the present embodiment, described connection chamber 101 connects in primary importance with described installation cavity 102, and described connection chamber 101 is positioned at above primary importance internal diameter from down to up and tapers into, it is positioned at below primary importance internal diameter from down to up to become larger, and minimum diameter is less than the diameter of ball sealer.
Being provided with iron core 304 on described base 301, described iron core 304 is positioned at described spring 303, can not only increase magnetic field intensity when spring 303 is energized, moreover it is possible to play the position-limiting action to block head 302.
Being provided with catching step 103 in described installation cavity 102, described catching step 103 becomes larger towards the side internal diameter of primary importance, and minimum diameter is less than the diameter of ball sealer.
Its operation principle is under normal circumstances, spring 303 is energized, and forms magnetic field, and ball sealer is in close contact with installation cavity 102 inwall, when needs block, spring 303 power-off, and extend, block head 302 moves to contact with catching step 103, ball sealer is pushed in connection chamber 101, no matter it upwards or moves downward, and all can be stopped by connection chamber 101 inwall of reducing and be tightly connected, reach to prevent the purpose of oil spill.
The above is preferred implementation of the present utility model; it should be noted that; for those skilled in the art; on the premise of without departing from this utility model principle; likely to concrete size; or partial structurtes go out some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
