Description
Technical field
The utility model relates to sealing devices before field more particularly to a kind of variable bore ram.
Background technique
Sealing, which can be divided into before half envelope cable, during traditional oil field wireline operation, before ram block seals and complete
Sealing before envelope, is respectively suitable for the sealing made in hermetically-sealed cable (steel wire) and well without cable, for being sealed to drilling rod, with
It prevents the pernicious gas in well from spraying, forms blowout, it is existing to need more ram preventers that half envelope and blind rams are installed respectively
Assembly must be dismantled before preventer replaces various sizes of cable in the case where cable or gage Size convert and be sealed, cause
Preventer structure size increases and inconvenient for use, so that working efficiency is low, operating cost is improved.
Utility model content
In view of the foregoing drawbacks or insufficient, the purpose of this utility model is to provide sealing device before a kind of variable bore ram, energy
Equipment and operating cost are enough reduced, operating efficiency is improved.
To achieve the above objectives, the technical solution of the utility model are as follows:
Sealing device before a kind of variable bore ram, including the colloid seal body symmetrically cooperated, the colloid seal body
Be provided with parallels up and down, the colloid seal body and parallels center be equipped with mutually block with cable and semi-circular recesses, it is described
Semi-circular recesses inner wall is covered with support chip group, and support chip group one end is clipped between colloid seal body and parallels, and the other end is set
It is placed in semi-circular recesses inner wall, when fluid cylinder pushes the movement of colloid seal body to squeeze, support chip group drives colloid seal body to squeeze
Opening is pressed to, so that opening diameter changes.
The support chip group includes the first support chip being arranged on colloid seal body side wall and is arranged in semicircle
Several second support chips of groove inner wall.
The first support chip quantity is two, and the second support chip quantity is four.
Second support chip is uniformly circumferentially distributed in semi-circular recesses inner wall.
The support chip group is two groups, is separately positioned on up and down between colloid seal body and parallels.
Compared with the prior art, the utility model has the following beneficial effects:
The utility model provides sealing device before a kind of variable bore ram, by the way that colloid seal body is arranged, by glue
Body seal body and conductive cable contacts face are provided with support chip group, when fluid cylinder pushes the movement extruding of colloid seal body, support chip group
It drives colloid seal body to be pressed against opening, so that opening diameter changes, and then various sizes of cable or steel wire can be sealed；
Continue to squeeze forward and can be achieved to be completely covered opening, realization is sealed entirely；Support chip realizes the branch to rubber in extrusion process
Support guarantees that rubber is not destroyed when on-line pressure sealant, and the utility model does not need to change preceding sealing i.e. after realizing cable or steel wire replacement
Sealing can be achieved, and hermetically sealed when in well without cable.Operation cable or steel wire use scope are improved, equipment and work are reduced
Industry cost improves operating efficiency.

Specific embodiment
The utility model is described in detail below in conjunction with attached drawing, it is clear that described embodiment is only that this is practical
Novel a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, belongs to the protection model of the utility model
It encloses.
As shown in Figure 1, the utility model provides sealing device before a kind of variable bore ram, the colloid including symmetrically cooperating is close
Ontology 1 is sealed, the upper and lower of the colloid seal body 1 is provided with parallels 3, and the colloid seal body 1 and 3 center of parallels are equipped with
Mutually block with cable and semi-circular recesses 2,2 inner wall of semi-circular recesses is covered with support chip group, and support chip group one end is clipped in
Between colloid seal body 1 and parallels 3, the other end is set to 2 inner wall of semi-circular recesses, when fluid cylinder pushes colloid seal body 1
Movement squeezes, and support chip group drives colloid seal body 1 to be pressed against opening, so that opening diameter changes.
Specifically, as shown in Fig. 2, the support chip group is two groups, colloid seal body 1 and parallels up and down are separately positioned on
Between 3.Parallels 3, support chip group vulcanize in colloid seal body 1；The support chip group includes that setting seals originally in colloid
The first support chip 4 on 1 side wall of body and several second support chips 5 that 2 inner wall of semi-circular recesses is set.
Illustratively, 4 quantity of the first support chip is two, and 5 quantity of the second support chip is four, wherein described the
Two support chips 5 are uniformly circumferentially distributed in 2 inner wall of semi-circular recesses, so that support chip is realized in extrusion process seals this to colloid
The support of body 1 guarantees that rubber is not destroyed when on-line pressure sealant.
The course of work and principle of the utility model are as follows:
As shown in figure 3, fluid cylinder pushes the movement of colloid seal body 1 to squeeze, support chip group band in hermetically-sealed cable or steel wire
Dynamic colloid seal body 1 is pressed against opening, so that opening diameter changes, and then can seal various sizes of cable or steel wire；
Continue to squeeze forward and can be achieved to be completely covered opening, realization is sealed entirely；Support chip is realized in extrusion process seals colloid
The support of ontology 1 guarantees that rubber is not destroyed when on-line pressure sealant, and the utility model does not need to change after realizing cable or steel wire replacement
Sealing can be realized in preceding sealing, and hermetically sealed when in well without cable, improves operation cable or steel wire use scope, reduces
