Abstract
The utility model discloses a nonrust steel pipe dry -type waterproofing type light unit, it is including center tube bank, block water linear pipe, the area that blocks water, non - metal shielding and nonrust steel pipe, the center tube bank round linear pipe that blocks water of having arranged all around, the linear outside of tubes that blocks water set up the one deck area that blocks water, the outband that blocks water sets up the non - metal shielding of one deck, non - metal shielding overcoat has a nonrust steel pipe, the center tube bank inside within a definite time position cloth have a central gasket for packing, the distribution has multifiber and fine cream around the central gasket for packing. Intrafascicular of center tube has a central gasket for packing for fine cream is around the gasket for packing equipartition, and tube bank outer block water linear pipe, the area that blocks water of setting up in succession in center has strengthened blocking water effect, stands high temperature, and the outband that is blocking water again sets up non - metal shielding and nonrust steel pipe, has protected intraductal optic fibre, and the effect of blocking water is played to intraductal to dry -type linear pipe the that block water, again can be at high temperature and can not be dirty when vertical, and the environment of suitable oil well.
Description
Technical field
The utility model relates to a kind of light unit, particularly relates to a kind of stainless-steel tube dry type waterproofing type light unit.
Background technology
Stainless steel tube optical unit is all form with steel band Bian laser or argon arc welding, while welding, optical fiber and fine cream is inserted in pipe simultaneously, like this pipe is made a seal.Base area spheric stress, things has gravity, and stainless steel tube optical unit is all set up sidewards when OPGW and submarine optical fiber cable application, optical cable lies low, and so fine cream and optical fiber can not out, but if be used in well, from the top down, optical cable is endways, thus fine cream and optical fiber along with gravity downward, add the high temperature of down-hole, make fine cream stream obtain faster, fine cream has not had, optical fiber or disconnected, or air enters light unit inside, makes fiber ageing quickening.
At present along with the exploitation in oil field, the Bian technology of opening of oil well is constantly updated, and uses comparatively high-grade instrument to be put into down-hole, come with in Optical Fiber Transmission in down-hole, the optical cable of such down-hole requires very high to high temperature resistance and block-water performance, inapplicable for the method for filling fine cream in stainless-steel tube.
Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of stainless-steel tube dry type waterproofing type light unit.
For solving the problems of the technologies described above, stainless-steel tube dry type waterproofing type light unit of the present utility model, it comprises center tube bank, the linear tube that blocks water, waterstop, non-metal reinforced layer and stainless-steel tube, described center tube bank surrounding is placed with a circle and blocks water linear tube, outside the described linear tube that blocks water, one deck waterstop is set, one deck non-metal reinforced layer is set outside described waterstop, described non-metal reinforced layer overcoat has stainless-steel tube, in the tube bank of described center, centre position is furnished with a center-filled rope, and described center-filled rope surrounding is distributed with multifiber and fine cream.
Further, described non-metal reinforced layer is aramid layers.
Further, the linear tube that blocks water described in is the gasket for packing that blocks water.
The beneficial effects of the utility model: intrafascicular of pipe core has a center-filled rope; make fine cream uniform around gasket for packing; center tube bank is outer arranges block water linear tube, waterstop continuously; enhance resistance effect; withstanding high temperatures; non-metal reinforced layer and stainless-steel tube are set outside waterstop again; protect the optical fiber in pipe; place dry type while placing optical fiber in stainless steel light cellular manufacture to block water linear tube; resistance effect is played in pipe; again can high temperature and vertical time can not be dirty, be applicable to the environment of oil well.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, stainless-steel tube, 2, optical fiber, 3, block water linear tube, 4, center tube bank, 5, waterstop, 6, non-metal reinforced layer, 7, center-filled rope, 8, fine cream.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As shown in Figure 1, stainless-steel tube dry type waterproofing type light unit of the present utility model, it comprises center tube bank 4, the linear tube that blocks water 3, waterstop 5, non-metal reinforced layer 6 and stainless-steel tube 1, center is restrained 4 surroundings and is placed with a circle and blocks water linear tube 3, one deck waterstop 5 is set outside the linear tube that blocks water 3, one deck non-metal reinforced layer 6 is set outside waterstop 5, non-metal reinforced layer 6 overcoat has stainless-steel tube 1, in center tube bank 4, centre position is furnished with a center-filled rope 7, and center-filled rope 7 surrounding is distributed with multifiber 2 and fine cream 8.
Above-mentioned non-metal reinforced layer 6 is aramid layers.
The above-mentioned linear tube 3 that blocks water is for the gasket for packing that blocks water.
For in prior art, in stainless-steel tube, directly fill fine cream, the high temperature of down-hole, makes fine cream stream obtain faster, fine cream has not had, and optical fiber is easily aging, and too fast in order to stop fine cream to run off, the utility model is also provided with the linear tube 3 that blocks water, arrangement is neat, and not easily run off, block-water effect is good.
In the middle of center tube bank 4, there is a center-filled rope 7; make fine cream 8 uniform around gasket for packing; center tube bank 4 is outer arranges block water linear tube 3, waterstop 5 continuously, enhances resistance effect, withstanding high temperatures; non-metal reinforced layer 6 and stainless-steel tube 1 are set outside waterstop 5 again; protect the optical fiber in pipe, place dry type while placing optical fiber in stainless steel light cellular manufacture and to block water linear tube, play resistance effect in pipe; again can high temperature and vertical time can not be dirty, be applicable to the environment of oil well.
