Abstract
The utility model relates to a device for preventing crude oil from blowout. The device comprises a casing, wherein a blowout preventing ball, a ball seat, compression springs and an air cylinder are mounted in the casing; the blowout preventing ball is fixed on the ball seat; one end of each compression spring is fixed on the casing, and the other end is connected with the ball seat; one end of the air cylinder is mounted on the casing, and the other end is connected with the ball seat; the casing is provided with an axial hole whose diameter is matched with the blowout preventing ball, the ball seat and the compression springs; and the air cylinder is connected with a controller. The device for preventing the crude oil from blowout can block the inlet of a pumping well timely to prevent crude oil from erupting of the pumping well when a polish rod fractures suddenly; normal work of the pumping well can be restored quickly after accident treatment; and the extraction of the blowout preventing ball from the pumping well is simple, easy, time-saving and labor-saving.
Description
Technical field
The utility model belongs to petrochemical industry, relates in particular to a kind of preventing because the polished rod fracture causes the device of crude oil blowout.
Background technology
In the process of pumpingh well oil pumping, polished rod is because long-term the use often causes mechanical wear or corrosion fracture suddenly, just cause the pumpingh well blowout this moment easily, not only cause the loss of resource property, and because the leakage of crude oil causes great pollution to environment, influence normally taking of oil.In order to prevent the generation of this class event, notice of authorization number is CN2630482Y, it is a kind of for oil, the chemical industry equipment preventer of pumpingh well well head particularly notice of authorization day to be that the Chinese utility model patent on August 4th, 2004 discloses, and it is made up of housing, connector, end cap and the spray-proof ball, ball seat, spring, the positioning bolt that are arranged in the housing.When this utility model ruptured suddenly at polished rod, spray-proof ball was stoped crude oil ejection well head by the spring-advance well head.But this utility model is because spray-proof ball and ball seat, spring are the branch body structures, spring has dropped in the pumpingh well after spray-proof ball is advanced pumpingh well, because the spray-proof ball diameter is slightly less than the well head diameter, it is very difficult that the workman takes out pumpingh well with spray-proof ball, time-consuming effort has again influenced the operate as normal of pumpingh well.
The utility model content
In order to overcome above-mentioned defective, the utility model discloses a kind of device that prevents the crude oil gusher, when polished rod ruptured suddenly, the utility model can in time stop up the pumpingh well import, prevented crude oil ejection pumpingh well.Can recover the pumpingh well operate as normal rapidly after accident treatment is intact, it is simple easy and time saving and energy saving to take out spray-proof ball from pumpingh well.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Prevent the device of crude oil gusher, comprise housing, it is characterized in that: spray-proof ball, ball seat, compression spring and cylinder are installed in the described housing, described spray-proof ball is fixed on the ball seat, described compression spring one end is fixed on the housing, the other end links to each other with ball seat, described cylinder one end is installed on the housing, the other end links to each other with ball seat, described housing is provided with an axial hole, described axial hole diameter and spray-proof ball, ball seat and compression spring are complementary, and described cylinder one end is installed in that the other end links to each other with ball seat on the housing, and described cylinder is connected with a controller.
Described compression spring is provided with two, is connected to ball seat two sides up and down.
Described compression spring is welded on the housing.
Described axial hole is a shoulder hole.
The utlity model has following advantage:
1, the utility model comprises housing, it is characterized in that: spray-proof ball, ball seat, compression spring and cylinder are installed in the described housing, described spray-proof ball is fixed on the ball seat, described compression spring one end is fixed on the housing, the other end links to each other with ball seat, described cylinder one end is installed on the housing, the other end links to each other with ball seat, described housing is provided with an axial hole, described axial hole diameter and spray-proof ball, ball seat and compression spring are complementary, described cylinder one end is installed in that the other end links to each other with ball seat on the housing, and described cylinder is connected with a controller.Under normal circumstances, the effect of the pressured contracting spring of spray-proof ball leaning against on the polished rod tightly, when polished rod ruptures suddenly, because the elastic force effect of compression spring, spray-proof ball was pushed out housing and entered in the pumpingh well this moment, cylinder stretches out along with moving of spray-proof ball this moment, after the workman recovered the pumpingh well operate as normal, the control controller shrank cylinder spray-proof ball is retracted in the housing, so just can recover operate as normal, because the utility model spray-proof ball, ball seat, compression spring and cylinder all link together, and spray-proof ball can not break away from the ball seat independently moving, and the workman controls controller and shrinks and spray-proof ball can be retracted housing by cylinder, time saving and energy saving, the efficient height.
2, the utility model compression spring is provided with two, is connected to ball seat two sides up and down.Two compression springs are connected to ball seat and can prevent the spray-proof ball unbalance stress in two sides up and down, are stuck in the housing, can't operate as normal.
3, the utility model axial hole is a shoulder hole, has both guaranteed the rigidity of housing, has also further prevented from being stuck in the spray-proof ball unbalance stress in the housing, can't operate as normal.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Mark 1, polished rod among the figure, 2, housing, 3, the compression spring, 4, cylinder, 5, ball seat, 6, spray-proof ball.
The specific embodiment
As shown in Figure 1, the utility model comprises housing 2, in the described housing 2 spray-proof ball 6 is installed, ball seat 5, compression spring 3 and cylinder 4, described spray-proof ball 6 is fixed on the ball seat 5, described compression spring 3 one ends are fixed on the housing 2, the other end links to each other with ball seat 5, described cylinder 4 one ends are installed on the housing 2, the other end links to each other with ball seat 5, described housing 2 is provided with an axial hole, described axial hole diameter and spray-proof ball 6, ball seat 5 and compression spring 3 are complementary, and described cylinder 4 one ends are installed in that the other end links to each other with ball seat 5 on the housing 2, and described cylinder 4 is connected with a controller.Under normal circumstances, the effect of the pressured contracting spring of spray-proof ball leaning against on the polished rod tightly, when polished rod ruptures suddenly, because the elastic force effect of compression spring, spray-proof ball was pushed out housing and entered in the pumpingh well this moment, cylinder this moment is along with the anti-collision ball moves and stretch out, after the workman recovered the pumpingh well operate as normal, the control controller shrank cylinder spray-proof ball is retracted in the housing, so just can recover operate as normal, because the utility model spray-proof ball, ball seat, compression spring and cylinder all link together, and spray-proof ball can not break away from the ball seat independently moving, and the workman controls controller and shrinks and spray-proof ball can be retracted housing by cylinder, time saving and energy saving, the efficient height.
