Abstract
The utility model provides a full/half dual-purpose single gate disc blowout preventer, which includes a body, a half seal type gate disc assembly and a full seal type gate disc assembly, wherein the half seal type gate disc assembly and the full seal type gate disc assembly are arranged in the same plane and correspondingly mounted in gate disc cavities on two sides of the body, a half seal type gate disc II corresponding to a half seal type gate disc I of the half seal type gate disc assembly is mounted at the front end of a full seal type gate disc of the full seal type gate disc assembly, and the half seal type gate disc I and the half seal type gate disc II form a set of completed half seal type gate disc pair. The utility model changes the left and right symmetrical structure of the present single gate disc blowout preventer, and adopts the half seal type gate disc assembly on one side and the full seal type gate disc assembly on the other side, thereby forming the single gate disc blowout preventer which can form half seal and full seal in the same plane, overcoming the defect that the single gate disc blowout preventer in the prior art can have only one of half seal and full seal functions, solving the problem that the present single gate disc blowout preventer is too high to operate conveniently, and efficiently improving the work efficiency.
Description
Technical field
The utility model relates to a kind of oil well control appliance, particularly a kind of half complete dual-purpose single ram type perventer.
Background technology
In oil drilling, well workover process, well kick and gas blowout accident happen occasionally, and must use preventer to seal well head, to guarantee the safety of operating personnel and equipment.Existing single ram type perventer mainly is made up of body and half-closed type flashboard assembly or full-enclosed type flashboard assembly; When in well head needs sealing and well head, oil pipe being arranged, adopt half-closed type flashboard assembly, hold oil pipe tightly, form semitight; When in the well head during no oil pipe, then adopt full-enclosed type flashboard assembly with the well head complete closed.Like this, just need a cover half-closed type ram preventer and a cover full-enclosed type ram preventer, be used alternatingly.This not only makes operating personnel's working strength increase, and the operating time of replacing preventer is longer, influences operating efficiency.For this reason, people have have now researched and developed double ram type preventer, half-closed type flashboard assembly and full-enclosed type flashboard assembly under presenting, it are installed with being provided with, with the labour intensity that alleviates the operator, save operating time of changing preventer, increase work efficiency in the body of preventer; But double ram type preventer has increased the operation height of overall height, weight and the raised platform around a well of preventer, has increased operator's work difficulty, has brought new inconvenience again for the operator.
The utility model content
For overcoming the deficiencies in the prior art part, the utility model provides a kind of half complete dual-purpose single ram type perventer of rational in infrastructure, dual-use material, it both can carry out half envelope operation to well head, can seal operation entirely to well head again, double ram type preventer than prior art, its height, weight reduce greatly, are convenient to operator's operation task, increase work efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: comprise body, half-closed type flashboard assembly and full-enclosed type flashboard assembly; Half-closed type flashboard assembly and full-enclosed type flashboard assembly are in same plane, are loaded in the flashboard die cavity of body both sides accordingly, the front end of the blind rams of full-enclosed type flashboard assembly be equipped with partly seal the flashboard assembly partly seal flashboard I symmetrical partly seal flashboard II, partly seal flashboard I and partly seal flashboard II and constitute one and overlap the complete flashboard that partly seals and pay.
The flashboard chamber type length L 1 of partly sealing flashboard assembly side of above-mentioned body is 2.1～2.3 times of half envelope flashboard I length L 2.
The beneficial effects of the utility model are: the bilateral symmetry structure that changes existing single ram type perventer, one side adopts half-closed type flashboard assembly, and opposite side adopts the band full-enclosed type flashboard assembly that partly seals flashboard, can half envelope thereby in a plane, constituted not only, but also the single ram type perventer that can seal entirely, realized dual-use material, the single ram type perventer that has overcome prior art has only half envelope or seals the defective of function entirely, solve the problem that existing double ram type preventer height is too high, be awkward, improved operating efficiency effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1 be half block tight leading screw, 2 be half sealed cover, 3 be half envelope side door, 4 be half block mandrel, 5 be half envelope flashboard I, 6 for body, 7 be main latus rectum, 8 for seal receptacle, 9 be that half envelope flashboard II, 10 is full sealed cover for full envelope side door, 14 for the complete tight nut, 13 that blocks for the complete tight leading screw, 12 that blocks for blind rams, 11.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model comprises: body 6, half-closed type flashboard assembly and full-enclosed type flashboard assembly; The middle part of body 6 is provided with main latus rectum 7, and the both sides, middle part of main latus rectum 7 are provided with left and right flashboard die cavity accordingly; Described half-closed type flashboard assembly include half block tight leading screw 1, half sealed cover 2, partly seal side door 3, partly block mandrel 4 and partly seal flashboard I5, partly seal in the left side flashboard die cavity that flashboard I5 places body 6, the length L 1 of this left side flashboard die cavity is 2.2 times of half envelope flashboard I5 length L 2.Described full-enclosed type flashboard assembly include blind rams 10, entirely block tight leading screw 11, entirely block tight nut 12, seal side door 13, full sealed cover 14 entirely; Full-enclosed type flashboard 10 places in the template chamber, right side of body 6, and the front end at blind rams 10 is equipped with half envelope flashboard II9 by wedge groove structure, this partly seal flashboard II9 with partly seal the flashboard assembly partly to seal flashboard 15 symmetrical, promptly partly seal flashboard 15 and partly seal flashboard II9 can constitute the complete half-closed type flashboard of a pair and pay.In the main latus rectum 7 of body 6, be positioned at the upper and lower seal receptacle 8 that is equipped with of left and right flashboard die cavity.
During use, at first the upper and lower opening flange of the utility model by its body 6 is installed on the well head of oil well.When in needs sealing oil well and the well head oil pipe being arranged, rotation is earlier partly blocked tight leading screw 1 driving and is partly sealed flashboard I5 to main latus rectum 7 centers, rotate the complete tight leading screw 11 that blocks again, drive and partly seal flashboard II9 to main latus rectum 7 central motions, partly sealing flashboard until both sides contacts and pushes, the preceding sealing generation slight deformation that makes half envelope flashboard I5 and partly seal flashboard II9 front end, thus hold oil pipe tightly, realize semitight.When needs during with the oil well complete closed, then rotate and partly block tight leading screw 1, to partly seal flashboard I5 and fall back on initial position, rotating the tight leading screw 11 of full blockade moves half envelope flashboard II9 left, until with partly seal flashboard I5 and closely conflict, this moment, blind rams 10 was blocked main latus rectum 7 fully, and formed sealing with seal receptacle 8, thereby realized hermetically sealed.
