Abstract
The utility model relates to an inflatable type sealing device of a secondary cable pipeline. The inflatable type sealing device comprises a bag, a film layer and a film strip, the film layer is adhered to two outer side walls of the bag, and one end of the film strip is connected to the bag and used for binding and winding the bag. The inflatable sealing device has the advantages that gaps formed by winding an inflatable sealing bag are filled by the inflatable sealing mode and in cooperation with the film layer and the film strip, so that the inflatable sealing device is good in sealing effect and high in sealing reliability, and the sealing effect is rarely influenced by external factors; the gaps formed between walls of the bag in winding and a gap between the bag and the secondary cable pipeline are filled by the arrangement of the film layer; the film strip is used for binding and winding the bag to prevent the bag from loosening, and on the other hand, the film strip is used for filling the gap between the bag and the inner wall of the secondary cable pipeline.
Description
The inflatable closure device of secondary cable pipeline.
Technical field
The utility model relates to a kind of sealing device, relates in particular to a kind of inflatable closure device of secondary cable pipeline.
Background technology
Secondary cable compares that cable exists that diameter is little, quantity is many, easily leave gap between cable and cable, be difficult for the feature of sealing etc.Existing common secondary cable seal for pipe joints method is taking plasticine as main.Plasticine has good airproof performance, the advantage that plasticity is strong.But there is following shortcoming in plasticine sealing: just can carry out seal operation after 1, needing hot water softening, therefore, also need to carry the auxiliary equipment such as insulating pot when operation; 2, under adverse circumstances, be easy to aging, sealing variation, Changes in weather causes to expand with heat and contract with cold and also can cause the disappearance of sealing; 3, biting of resistance to toy do not stung; 4, very not convenient to the cable dilatation after sealing yet.So there is larger defect in existing secondary cable seal for pipe joints method therefore.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists and a kind of inflatable closure device of secondary cable pipeline is provided, adopt the mode of inflation to seal, and coordinate film layers and film strip, fill the gap that gas-flow closure bag is wound, good sealing effect, sealing reliability is strong, and it is little that sealing effectiveness is affected by extraneous factor.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the inflatable closure device of secondary cable pipeline, it is characterized in that comprising bag, be fitted in the film layers on bag two lateral walls, and one end is connected on bag for bundling the film strip that is wound around bag.Adopt the mode of inflation to seal, and coordinate film layers and film strip, fill the gap that gas-flow closure bag is wound, good sealing effect, sealing reliability is strong, and it is little that sealing effectiveness is affected by extraneous factor.Being provided for filling of film layers is wound around the gap producing between bag wall, and gap between bag and secondary cable pipeline.Arranging on the one hand for bundling the bag of winding of film strip, avoids bag loose, fills on the other hand the gap between bag and secondary cable inner-walls of duct.
As the further of technique scheme improved and supplemented, the utility model adopts following technical measures: described bag is that three-decker is composited, by interior metal level, layer of silica gel and the gum layer of comprising successively outward.Being provided for gaining in strength of metal level avoided fracture.The setting of layer of silica gel is by the self sealss of self, when inflation completes can self sealss after extracting gas-filled tube, avoid gas leakage.The setting of gum layer has enough pliabilities and anti-puncture (toy is bitten and stung) ability.
For convenient inflation, described bag is provided with plug-in gas-filled tube.
In order to be conveniently wound around and to guarantee to have the described bag of harmony of sufficient length and winding dynamics and coated degree elongated.
The beneficial effect the utlity model has: adopt the mode of inflation to seal, and coordinate film layers and film strip, fill the gap that gas-flow closure bag is wound, good sealing effect, sealing reliability is strong, and it is little that sealing effectiveness is affected by extraneous factor.Being provided for filling of film layers is wound around the gap producing between bag wall, and gap between bag and secondary cable pipeline.Arranging on the one hand for bundling the bag of winding of film strip, avoids bag loose, fills on the other hand the gap between bag and secondary cable inner-walls of duct.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the inflatable closure device of secondary cable pipeline, as shown in Figure 1, comprise that certain other shapes of elongated bag 1(are also feasible, just strip is preferred version), be fitted in the film layers 3 on 1 liang of lateral wall of bag, and one end is connected on bag 1 for bundling the film strip 5 that is wound around bag 1.Film strip 5 also can coordinate with bag 1 by the mode of binding.For convenient inflation, bag 1 is provided with plug-in gas-filled tube 4.
Bag 1 is for three-decker is composited, by interior metal level 11, layer of silica gel 12 and the gum layer 13 of comprising successively outward.Being provided for gaining in strength of metal level avoided fracture.The setting of layer of silica gel is by the self sealss of self, when inflation completes can self sealss after extracting gas-filled tube, avoid gas leakage.The setting of gum layer has enough pliabilities and anti-puncture (toy is bitten and stung) ability.
The bag of inflation provides the sealing of large space between secondary cable and cable duct wall; The sealing in little space between secondary cable and sealing bag, bag, between secondary cable is provided by the film layers on sealing bag and film strip.
Not only good sealing effect of the sealing device of present patent application, intrusion that can also anti-sealing, keeps dry in cable duct, for the operation of cable provides a good environment; And be convenient to dilatation and maintenance in the future, slightly fire prevention, simple in structure, load and unload easy; In addition, can stop toy to enter secondary cable pipeline and bite and sting secondary cable skin, avoid the generation of the situation of the cable grounding that therefore causes or even protective relaying device malfunction.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model.In the above-described embodiments, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
