Abstract
A armored optical cable of water proof type is featured as packing water proof oleamen in layer stranded cable core, coating a layer of oleamen being able to be expanded when it is contacted with water on internal surface of armored layer and cladding an external protective sheath on external of armored layer. The device used for injecting and coating said oleamen is also disclosed.
Description
Technical field
The present invention relates to a kind of waterproof armouring optical cable, the ointment injection coating that relates in particular to the stop water of layer-twisted type waterproof armouring optical cable and be used for this optical cable protective layer equipment is put.
Background technology
The mechanism of existing layer-twisted type waterproof armouring optical cable mainly comprises cable core, armor and oversheath, is filled with greasy for preventing water between armor and cable core.In the optical cable water-blocking structure, for optical fiber in the protection cable is avoided the corrosion influence of water, in the manufacture process technological requirement that blocks water is strict the especially requirement that blocks water between armor and cable core.Normally carrying out earlier ointment on cable core or center strengthening core fills, the ointment of filling is the water-swellable ointment that contains water-proofing powder, before sheath, finish whip stitch place resistance effect then, to satisfy the process requirements of optical cable water-blocking at the whip stitch place of armouring metal tape coating thermosol or at armouring steel, aluminium strip surface sprinkling greasy for preventing water.Adopt the existing problem of armouring optical cable of above-mentioned stop water to be: 1, water-swellable ointment and thermosol price height, the cost of manufacture of optical cable is raise, and the water-proofing powder in the ointment, wearing and tearing to pneumatic type pressure filling pump are bigger, easily cause the wearing and tearing of pump housing pipeline, cause that ointment leaks, thereby influence cable core ointment filling quality; 2, thermosol is coated with in the process at notes, and during high temperature, the easy carbonization of colloid easily cause system pipeline to stop up, and the cleaning of line clogging is very inconvenient, if stop up seriously, can influence the processing work efficiency of optical cable protective layer.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of cost of manufacture low at the deficiency of above-mentioned prior art existence, processes comparatively easy waterproof armouring optical cable and the ointment injection coating in the sheath equipment thereof and puts.
The technical scheme of waterproof armouring optical cable of the present invention is: include layer-twisted type cable core, armor 10 and oversheath 13, its difference is to fill water proofing property ointment 11 in the layer-twisted type cable core, inner face at armor applies a water-swellable ointment layer 12, and armor coats oversheath outward.
Press such scheme, described layer-twisted type cable core is tangled by the sleeve pipe 8 of jacketed fiber and strengthening core 9 and forms; Described armor is made of the vertical bag of metal tape cable core.
Press such scheme, the water-swellable ointment layer 12 of described armor inner face is to annotate at the inner face of metal tape to be coated with one deck water-swellable ointment and to be formed by the vertical bag of metal tape cable core then, the bed thickness of water-swellable ointment layer 12 is 0.5～3mm, can be vertically continuously or be interrupted to annotate and be coated with along metal tape, constitute continuously or be interrupted water-swellable ointment layer; Whip stitch place at the vertical bag of metal tape can converge more amount water-swellable ointment.
The injection coating of the water-swellable ointment layer in the sheath equipment of the present invention is put technical scheme and is: include pump 1 and filtrator 2, the input end of pump is communicated with ointment bucket 4 through filter 2, delivery side of pump links to each other with filling and coating gun 7 through electrically-controlled valve 3, and the notes of described filling and coating gun are coated with mouthful that to be coated with width corresponding with the ointment notes.
Press such scheme, the notes of described filling and coating gun 7 are coated with mouthful and are narrow slit shape, and annotating the length that is coated with mouthful and ointment notes, to be coated with width corresponding.
Press such scheme, described pump 1 is a single-screw (single screw) pump, and pump links to each other with variable-frequency motor, and by frequency converter 6 controls; Described electrically-controlled valve 3 is the high-frequency electromagnetic operation valve.
Beneficial effect of the present invention is: the water-swellable ointment of 1, filling in the cable core is changed to the water proofing property ointment, only the inner face at armor applies thin water-swellable ointment layer, cancelled simultaneously at the whip stitch place of armouring metal tape coating thermosol, this has not only saved the use amount of water-swellable shape ointment greatly, the material and the cost of manufacture of optical cable have been reduced, simplified fiber optic cable production technology, and the water proofing property ointment does not contain the water-proofing powder composition, less to the air driven pump pump housing wearing and tearing that former conveying ointment is used, long service life, the failure rate of equipment are low; 2, the water-swellable ointment layer of armor inner face coating can effectively form the protective layer that blocks water between cable core and armor, notes are coated in water-swellable ointment on the metal tape in vertical packet procedures, be subjected to the extruding of cable core, ointment can be spread to the metal tape edge, make the water-swellable ointment form water baffle bar one at metal tape overlapping edges place, the water stop function of optical cable is strengthened fully; 3, the injection coating that water-swellable ointment layer is set in sheath equipment is put, this device adopts single-screw (single screw) pump, and be equipped with the high-frequency electromagnetic operation valve and control gel quantity, can accurately be coated to the vertical belt surface that belongs to covered with gold leaf to the water-swellable ointment equably, under the very high situation of linear speed, filling and coating gun also can respond rapidly, accurately the amount of being coated with is annotated in control; And the characteristics of single-screw (single screw) pump are to have stronger wear-resisting and anticorrosive property, effectively transfer of highly viscous contains the ointment of water-proofing powder, failure rate is low, control by frequency control motor, the conveying of ointment can be regulated automatically along with the speed of producing linear speed, thereby improved the transmission efficiency of ointment, arrived the accurately target of control paste volume.
