Abstract
The invention discloses a wedge disc body which is mainly a wedge disc body in a double-sided wedge disc structure. The wedge disc body is of an integrated rubber core type; a wedge disc is composed of three parts including the wedge disc body, a rubber core and a pressing block, wherein the rubber core is inlaid in the wedge disc body; the wedge disc body can be adjusted according to the size of the rubber core to ensure that the rubber core fits the wedge disc body in structure better; and the pressing block is arranged on the rubber core and is fixedly arranged in a groove of the rubber core by using four screws. The sealing effect is achieved by extrusion deformation of the rubber core; the wedge disc body disclosed by the invention is labor-saving in operation, safe in use, simple in maintenance and the like; and the adjustable wedge disc body can fit the rubber core better, so that the sealing effect is better, and the functional characteristics of the wedge disc body are improved.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of flashboard body.
Background technology
Annular space between ram preventer energy closed casing and tubing string, can totally-enclosed well head.Under encapsulation situations, the pipeline connected by bottom four-way or housing waste outlet port, carries out the operations such as circulation of drilling fluid, throttling open flow, kill-job.In a special case, the object that drilling tool reaches shut-in well can be cut off.
The automatic sand removal of gate panel floatation, flashboard and well pressure help the automatic centering of envelope, flashboard and certainly enter effect.Ram preventer sealing wellhead will have sealing everywhere to work simultaneously, just can reach effective shut-in well, that is: the sealing of the sealing of the sealing of the sealing of flashboard top and housing, flashboard front end and pipe, housing and side door, piston rod and side door.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of flashboard body, can regulate according to the size of glue core, make glue core and flashboard body structure more identical.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of flashboard body, the flashboard body mainly in a kind of overall glue core type flashboard structure, is characterized in that, flashboard is by flashboard body, glue core, briquetting three part is formed, and inlays glue core in described flashboard body, described flashboard body can regulate according to the size of glue core, glue core and described flashboard body structure more identical, be briquetting above described glue core, described briquetting two screws are fixed in the groove of described glue core.
Further, the flashboard body in described overall glue core type flashboard, glue core, briquetting three part inlay are tight.
Further, the surface area of described flashboard body be greater than described glue wicking surface amass.
Further, described described glue wicking surface is long-pending is greater than described briquetting surface area.
The invention has the beneficial effects as follows: a kind of flashboard body of the present invention, sealing function is realized by the crimp of glue core, there is rapid operation, use safety, the feature such as easy to maintenance, adjustable flashboard body better and glue core matches thus sealing effectiveness is better, enhances the functional characteristic of flashboard body.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of flashboard body of the present invention.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A kind of flashboard body, flashboard body mainly in a kind of overall glue core type flashboard structure, it is characterized in that, flashboard is by flashboard body, glue core, briquetting three part is formed, three part inlay are tight, glue core is inlayed in described flashboard body, described flashboard body can regulate according to the size of glue core, glue core and described flashboard body structure more identical, briquetting above described glue core, described briquetting two screws are fixed in the groove of described glue core, the surface area of described flashboard body is greater than described glue wicking surface and amasss, described described glue wicking surface is long-pending is greater than described briquetting surface area.Realize sealing function by the crimp of glue core, the rubber between briquetting and flashboard body is extruded upwardly, presses close to the seal boss face at top, flashboard room, thus completes whole sealing.When flashboard is opened, top seal rubber departs from housing boss face, is retracted in flashboard plane, continues to open flashboard, get back to initial point.Flashboard has floatability, has both ensured that sealing is reliable, reduces rubber wearing and tearing, extend glue core application life, have the frictional force decreased when flashboard moves, use safety, rapid operation, adjustable flashboard body better and glue core matches thus sealing effectiveness is better, enhances the functional characteristic of flashboard body.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
Claims (4)
1. a flashboard body, flashboard body mainly in a kind of overall glue core type flashboard structure, it is characterized in that, flashboard by flashboard body, glue core, briquetting three part is formed, inlay glue core in described flashboard body, described flashboard body can regulate according to the size of glue core, glue core and described flashboard body structure more identical, be briquetting above described glue core, described briquetting four screws are fixed in the groove of described glue core.
2. a kind of flashboard body according to claim 1, is characterized in that, the flashboard body in described overall glue core type flashboard, glue core, briquetting three part inlay are tight.
