Abstract
The invention relates to a two-way blowout prevention valve, which comprises a valve body in which a hollow cavity is provided, wherein two rotary pins in symmetry relative to the axis of the valve body are provided on side faces of the valve body; the end of each rotary pin is provided with a bowl-shape ball valve extending to the cavity body; the bowl-shape ball valves correspond to the inner contour of the cavity body; the upper part and the lower part of the bowl-shape ball valve at each side are respectively provided with an upper valve seat and a lower valve seat; the outer sides of the upper valve seat and the lower valve sea are provided with springs; and the springs are arranged on spring seats in the cavity body. The two-way blowout prevention valve provided by the invention has a novel structure and stable performance, and is convenient and simple in use. When well blowout occurs, a blowout preventer closes the annular space of an oil sleeve, and a two-way blowout prevention plug valve can close an oil pipe channel rapidly, thereby effectively stopping the development of the well blowout accident.
Description
Technical field
The present invention relates to the two-way blowout prevention valve of grease proofing blowout in a kind of oil field operation.
Background technology
In the well control operation of oil field, because strata pressure is big, the blowout phenomenon takes place in crude oil easily, and one causes the damage of relevant device, and two cause the waste of crude oil, simultaneously surrounding enviroment is polluted, and is badly in need of the two-way blowout prevention valve of a kind of well blowout preventing of invention.
Summary of the invention
The present invention is directed to above-mentioned defective, it is a kind of in the well control operation of oil field that purpose is to provide, and can effectively prevent the two-way blowout prevention valve of crude oil blowout phenomenon.
Technical scheme of the present invention is: the valve body of establishing cavity in the present invention includes; Two rotating dogs about the valve axis symmetry are established in the valve body side; The end of each rotating dog is established the bowl type ball valve that extends to cavity, and the interior profile of bowl type ball valve and cavity is corresponding, and the bowl type ball valve top and the bottom of every side are established upper valve base and lower valve base respectively; Spring is established in the outside of upper valve base and lower valve base, and spring is arranged on the spring base in the cavity.
Be provided with the O RunddichtringO between bowl type ball valve and upper valve base and the lower valve base.
Advantage of the present invention is: novel structure of the present invention, and stable performance, simple and easy to use.When blowout took place, preventer cut out oil casing annular space, and two-way blowout prevention plug valve can cut out the oil pipe passage rapidly, effectively prevents the generation of gas blowout accident.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is that valve body, 2 is that cavity, 3 is that spring base, 4 is that spring, 5 is that upper valve base, 6 is that O RunddichtringO, 7 is that a bowl type ball valve, 8 is that rotating dog, 9 is a lower valve base among the figure.
The specific embodiment
Establish the valve body 1 of cavity 2 in the present invention includes; Two rotating dogs 8 about valve body 1 axis symmetry are established in valve body 1 side, and the end of each rotating dog 8 is established the bowl type ball valve 7 that extends to cavity, and the interior profile of bowl type ball valve 7 and cavity is corresponding; Bowl type ball valve 7 top and the bottom of every side are established upper valve base 5 and lower valve base 9 respectively; Spring 4 is established in the outside of upper valve base 5 and lower valve base 9, and spring 4 is arranged on the spring base 3 in the cavity, is provided with O RunddichtringO 6 between bowl type ball valve 7 and upper valve base 5 and the lower valve base 9.
The present invention is open in usual at ordinary times, when blowout takes place, closes two-way blowout prevention plug valve, can close the oil pipe passage rapidly, and preventer cuts out oil casing annular space, effectively prevents the generation of gas blowout accident.
In the well control operation, hose when high pressure pipe joint damages, is closed this device, can carry out safe replacing.
