The blowout preventer comprises an upper joint, a lower joint and blowout preventing mechanisms which are connected with the upper joint and the lower joint and arranged bilaterally symmetrically, wherein each blowout preventing mechanism comprises a blowout preventing device, a blowout preventing gland, a valve rod and a blowout preventing valve plate, the blowout preventing gland is arranged at the outer end of the blowout preventing device, the valve rod penetrates through the blowout preventing gland and the blowout preventing device sequentially; a hand wheel is arranged at the head end of the valve rod, and the tail end of the valve rod is connected with the blowout preventing valve plate through a valve plate iron core. With the adoption of the structure, the valve plates are in closed and sealed states by the aid of the operation of the bilaterally and symmetrically arranged blowout preventing mechanisms, and blowout accidents can be prevented; and the operation difficulty and the strength are reduced by the blowout preventer, the reliability is good, the service life is long, the construction efficiency is improved, blowout can be prevented timely and effectively, and personal safety of an oil worker and the surrounding environment are protected. Besides, the blowout preventer for oil field equipment has the characteristics of reasonable design, simple structure, convenience in operation and the like.
Description
Technical field
The utility model relates to oil field equipment technical field, is specifically related to oil field equipment preventer.
Background technology
Nowadays, in oilfield downhole operation process, easily there is gas blowout accident, due to the generation of gas blowout accident, thereby oil worker's personal safety and surrounding environment are caused to irremediable loss.The preventer complex structure of prior art, operation inconvenience, increases task difficulty and intensity, and poor reliability, life-span are short, cause efficiency of construction low, can not reach in time, the effective object of blowout prevention.
Summary of the invention
The purpose of this utility model is to provide the oil field equipment preventer that a kind of reasonable in design, simple in structure, easy to operate, good reliability, life-span are long, improve efficiency of construction.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: oil field equipment preventer, comprises top connection, lower contact, the described top connection of connection and lower contact left and right symmetrically arranged anti-spraying mechanism; Described anti-spraying mechanism comprises blowout hookup, blowout-proof pressure cap, valve rod and blowout prevention valve plate, described blowout hookup outer end is provided with blowout-proof pressure cap, described valve rod runs through blowout-proof pressure cap and blowout hookup successively, the head end of described valve rod is provided with handwheel, and the end of described valve rod is connected with blowout prevention valve plate by valve plate iron core.
Further, the lower contact of described preventer is provided with the kill-job passage vertical with described lower contact, and the port of described kill-job passage is provided with kill-job plug.
The utlity model has following beneficial effect: oil field equipment preventer described in the utility model, mainly comprise top connection, lower contact, connection top connection and lower contact left and right symmetrically arranged anti-spraying mechanism, wherein, anti-spraying mechanism comprises blowout hookup, blowout-proof pressure cap, valve rod and blowout prevention valve plate; The utility model adopts said structure; by left and right symmetrically arranged anti-spraying mechanism operation, valve plate is reached and close sealing state; can avoid occurring gas blowout accident; this preventer reduces task difficulty and intensity; good reliability, life-span length, the efficiency of construction that improves; the object that can reach timely, effective blowout prevention, is conducive to protect oil worker's personal safety and surrounding environment.In addition, the utlity model has the features such as reasonable in design, simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, oil field equipment preventer, comprises top connection 1, lower contact 2, connects described top connection 1 and lower contact 2 left and right symmetrically arranged anti-spraying mechanism, described anti-spraying mechanism comprises blowout hookup 3, blowout-proof pressure cap 4, valve rod 5 and blowout prevention valve plate 6, described blowout hookup 3 outer ends are provided with blowout-proof pressure cap 4, described valve rod 5 runs through blowout-proof pressure cap 4 and blowout hookup 3 successively, wherein, between blowout-proof pressure cap and blowout hookup, can be provided with offset plate, can make like this between blowout-proof pressure cap and blowout hookup be connected tightr, firmly, the head end of described valve rod 5 is provided with handwheel 7, wherein, handwheel is connected by nut with valve rod, the end of described valve rod 5 is connected with blowout prevention valve plate 6 by valve plate iron core 8, blowout prevention valve plate is fixedly connected with the end of valve rod by valve plate is unshakable in one's determination, and between the inwall of and blowout hookup unshakable in one's determination at valve plate, between valve rod and blowout-proof pressure cap wall, can be provided with O type circle, can strengthen like this sealing effectiveness.In the present embodiment; first this anti-Apparatus for spraying and jetting particulate materials is connected with import, then by left and right symmetrically arranged handwheel, rotates simultaneously, thereby the valve rod on both sides is rotated; make to be closely connected with the blowout prevention valve plate on the both sides that are fixedly connected with valve rod; make blowout prevention valve plate in closed condition, thereby can effectively prevent gas blowout accident, easy to operate; good reliability; life-span is long, improves efficiency of construction, is conducive to protect oil worker's personal safety and surrounding environment.
As shown in Figure 2, the lower contact 2 of described preventer is provided with the kill-job passage 9 vertical with described lower contact 2, and the port of described kill-job passage 9 is provided with kill-job plug 10; In the present embodiment, occurring during blowout, first to close preventer, by connect supercharger at kill-job plug place, by kill-job passage, pressurize, the pressure in can balance oil pipe, thus avoid gas blowout accident, further improve the reliability of preventer.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
