Abstract
The invention discloses a novel high-strength blowout preventer in a top driving device. The novel high-strength blowout preventer comprises a body, wherein the body is provided with a lower valve seat and an upper valve seat; a ball valve is arranged between the lower valve seat and the upper valve seat; each of two sides of the ball valve is provided with a rotary knob; each rotary knob is provided with a stationary bushing; trisected slots are formed in corresponding positions of the rotary knobs and the stationary bushings; a lower baffle ring is arranged at the side, close to the ball valve, of the upper valve seat, and an upper baffle ring is arranged at the side, far away from the ball valve, of the upper valve seat; a sliding gasket is arranged between each stationary bushing and each rotary knob; and the lower valve seat, the upper valve seat and the ball valve are fastened on the body through screw threads and are pre-tightened through flange plates. The novel high-strength blowout preventer has the characteristics of 90-DEG opening/closing accuracy, portability and the like because of being fixed by using the trisected slots formed in the stationary bushings and the rotary knobs; no deep slots are needed turned in the body; and the strength of the novel high-strength blowout preventer is twice as much as that of the old-fashioned high-strength blowout preventer.
Description
Technical field
The present invention relates to a kind of top driving device inner blowout preventer, particularly a kind of high-strength novel top driving device inner blowout preventer, belongs to oil exploration equipment technical field.
Background technology
Top driving device be drillng operation must device, conventional top is driven and is generally adopted electro-motor (or hydraulic motor) driven wheel reduction box, then carries out rotary drilling operations by gear reduction box drive shaft.Existing oil drilling electric top driving device itself has interior blowout prevention function, namely during normal drilling well, needs first top to be driven after inner blowout preventer opens, restarts borehole pump, make drilling fluid set up circulation.When connecing column, round trip, top need be closed and drive inner blowout preventer, drive to drilling floor surface spray drilling fluid to prevent top.
But this inner blowout preventer easily near knob position pierce through, the phenomenons such as crackle, simultaneously its structure to be got on the bus the locating surface of deep trouth as knob at body, its product strength is greatly affected like this, need regular replacing, not only bother, and take time and effort.Given this, be necessary to improve traditional top driving device inner blowout preventer, solve current Problems existing with this.
Summary of the invention
The object of the invention is the drawback in order to solve present stage top driving device inner blowout preventer, and blowout hookup in a kind of high-strength novel top driving device proposed.Slotted by the trisection of stationary bushing and knob fixing, have 90 degree of switches accurate, the characteristic such as light, without car degree of depth groove in body, intensity doubles than old-fashioned.
To achieve these goals, present invention employs following technical scheme:
A kind of high-strength novel top driving device inner blowout preventer, comprise body, described body is respectively arranged with lower valve base and upper valve base, ball valve is provided with between described lower valve base and upper valve base, the both sides of described ball valve are provided with knob, described knob is provided with stationary bushing, and described knob and stationary bushing corresponding position offer trisection fluting.
As a preferred technical solution of the present invention, described upper valve base is provided with lower baffle ring near the side of ball valve, and the side away from ball valve is provided with upper baffle ring.
As a preferred technical solution of the present invention, between described stationary bushing and knob, be provided with sliding mats.
As a preferred technical solution of the present invention, described lower valve base, upper valve base and ball valve are all threadedly secured on body, and by flange pretension.
The invention has the beneficial effects as follows: slotted by the trisection of stationary bushing and knob fixing, have 90 degree of switches accurate, the characteristic such as light, without car degree of depth groove in body, intensity doubles than old-fashioned.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of high-strength novel top driving device inner blowout preventer described in the embodiment of the present invention;
Number in the figure: 1, main body; 2, lower valve base; 3, ball valve; 4, stationary bushing; 5, knob; 6, sliding mats; 7, lower baffle ring; 8, upper valve base; 9, upper baffle ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
With reference to Fig. 1, a kind of high-strength novel top driving device inner blowout preventer, comprise body 1, described body 1 is respectively arranged with lower valve base 2 and upper valve base 8, ball valve 3 is provided with between described lower valve base 2 and upper valve base 8, the both sides of described ball valve 3 are provided with knob 5, and described knob 5 is provided with stationary bushing 4, and described knob 5 and stationary bushing 4 corresponding position offer trisection fluting.
Wherein, described upper valve base 8 is provided with lower baffle ring 7 near the side of ball valve 3, and the side away from ball valve 3 is provided with upper baffle ring 9; Sliding mats 6 is provided with between described stationary bushing 4 and knob 5; Described lower valve base 2, upper valve base 8 and ball valve 3 are all threadedly secured on body 1, and by flange pretension.
The present invention is the matching used a kind of inner blowout preventer of top drive system, upper end connects top drive drilling swivel head, protection joint is driven on connection top, lower end, can bear from both up and down to high pressure when when normal drilling well, after opening top driving device inner blowout preventer, restart borehole pump, drilling fluid is made to carry out Inner eycle, now this device is slotted fixing by stationary bushing 4 and the trisection of knob 5, there are 90 degree of switches accurate, the characteristic such as light, body 1 is interior without car degree of depth groove simultaneously, intensity doubles than traditional, not only service efficiency and safety high, and long service life, without the need to regular replacing.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
