Abstract
The utility model discloses a kind of cable inflatable pipeline sealing device: it is characterized in that arranging inflatable seal band, described inflatable seal band forms a closed flat-shaped body by hollow belt, the waterproof film forming integrative-structure with band is had in the surface recombination of described inflatable seal band, and at the gas-filled tube that one end of described inflatable seal band is provided with inflation inlet and is communicated with described inflation inlet, in described inflation inlet, be provided with inflation unidirectional valve.The utility model adopts flexible blockage technology, and one solves the whole issue that existing cable pipeline exists, and by application " cable inflatable pipeline sealing device ", it can not cause physical damage to pipeline, only need use the shutoff again of Puffer-type cable sealing strip.
Description
Technical field:
The utility model relates to a kind of cable inflatable pipeline sealing device.
Background technology:
18 of party clearly proposes greatly the route map built beautiful China and realize " Chinese dream ", and actively pushing forward urbanization has become one of predominating path of China's socio-economic development between the coming years.Estimate between following 3 to five years, along with the quick propelling of nationwide urbanization strategy, a large amount of reconstructions of the old city town and New Town Construction will be carried out in each department, very fast growth will be there will be to the demand of cable, and to carry out protecting for buried cable be very important, prior art is for adopting the material shutoff cable ducts such as cement, the shortcoming of this way can lose waterproof effect because expanding with heat and contract with cold cracking between material and pipeline, cable carries out the operations such as maintenance and will destroy seal for pipe joints in addition, need reseal; Moreover, need to recover just may destroy whole pipeline because pipeline has been fixed to block, also inconvenient to cable dilatation in the future.
This utility model technology then adopts flexible blockage technology, integrally solves above-mentioned serial whole issue, and by application " cable inflatable duct enclosure systems ", it can not cause physical damage to pipeline, only need use the shutoff again of Puffer-type cable sealing strip.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of cable inflatable pipeline sealing device, adopt flexible blockage technology, integrally solve above-mentioned serial whole issue, by application " cable inflatable pipeline sealing device ", it can not cause physical damage to pipeline, only need use the shutoff again of Puffer-type cable sealing strip.
The utility model technical solution problem adopts following technical scheme:
Cable inflatable pipeline sealing device:
Inflatable seal band is set, described inflatable seal band forms a closed flat-shaped body by hollow belt, the waterproof film forming integrative-structure with band is had in the surface recombination of described inflatable seal band, and at the gas-filled tube that one end of described inflatable seal band is provided with inflation inlet and is communicated with described inflation inlet, in described inflation inlet, be provided with inflation unidirectional valve.
Adopt above-mentioned sealing device to carry out an encapsulating method for cable duct, carry out according to the following steps:
1), cleaning cable inner surface of pipeline;
2), tear the protection sheet of inflatable seal band outside off, if pipeline to be sealed is polyethylene pipe, then with lubricator lubricate at inner-walls of duct;
3), the inflatable seal band of flat-shaped body is rolled, and the band rolled is sent into cable, band is provided with one end of inflation inlet towards pipeline oral area, along cable by the band rolled with the form sliding inlet pipe road unreeled, until entire volume band is decontroled in flat-shaped body completely;
4), gas-filled tube is connected to aerating device to be communicated with source of the gas;
5), to band inner chamber inflate, until the air pressure in band reaches 3.5Mpa, make the pressure in band keep this numerical value to be no less than 30 seconds, pull out gas-filled tube, cable duct has sealed.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) install fast convenient, the very first time that can enter pipeline at cable gives cable protective;
(2) blank pipe and multi-cable all can be applied;
(3) remove easy, and without hindering cable and pipeline;
(4) PVC, PE, C-PVC, iron, steel pipe and various pipeline is applicable to;
(5) strict environment (salt, bacterium, white ants chemically corrosive deposit) can be resisted;
(6) more than 30 years useful life.
Accompanying drawing illustrates:
Fig. 1 is the deployed condition structural representation of the utility model band; Fig. 2 is the schematic cross-section after band inflation.
Number in the figure: 1 inflatable seal band, 2 waterproof films, 3 inflation inlets, 4 gas-filled tubes.
Below by way of embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: inflatable seal band 1 is set, described inflatable seal band forms a closed flat-shaped body by hollow belt, the waterproof film 2 forming integrative-structure with band is had in the surface recombination of described inflatable seal band, and the gas-filled tube 4 being provided with inflation inlet 3 in one end of described inflatable seal band and being communicated with described inflation inlet, inflation unidirectional valve is provided with in described inflation inlet 3, generally, inflatable structure is similar to the inflation inlet of water wing and so on.In concrete enforcement, band adopts the inflatable seal band become by soft metal and layer high molecule combination of materials, ensures that shutoff position is in complete water seal state, avoids sewage, foreign material, toy enter in pipeline, thus reach protection effect.This application of installation, in one section of complete pipeline (this segment pipe is without other interfaces) two ends, by installing this Puffer-type cable sealing strip in pipe ends, makes pipeline inner cable be adequately protected.
Adopt above-mentioned sealing device to carry out the encapsulating method of cable duct, carry out according to the following steps:
1), cleaning cable inner surface of pipeline, the wet cloth of suggestion cleans;
2), tear the protection sheet of inflatable seal band outside off, if pipeline to be sealed is polyethylene pipe, then with lubricator lubricate at inner-walls of duct;
3), the inflatable seal band of flat-shaped body is rolled (band about 100 centimeters is long, 10 centimeters wide, actual conditions depending on concrete pipeline determine length and the width of band, so-called width and the diameter after inflating), and the band rolled is sent into cable, band is provided with one end of inflation inlet towards pipeline oral area, along cable by the band rolled with the form sliding inlet pipe road unreeled, until entire volume band is decontroled in flat-shaped body completely; If be provided with two cables in pipeline, also aeration zone is unreeled propelling along cable, but along the cable that diameter is larger, band need be extended in pipeline;
4), gas-filled tube is connected to aerating device to be communicated with source of the gas;
5), to band inner chamber inflate, until the air pressure in band reaches 3.5Mpa, make the pressure in band keep this numerical value to be no less than 30 seconds, pull out gas-filled tube, cable duct has sealed.
If need recovery cable, then the method for dismounting of band and step as follows:
To exert oneself puncture through seal band with screwdriver, make the gas light leak of band, continue with screwdriver, band to be separated with cable duct wall;
With pliers, band is taken out by pipeline;
Dismounting completes, and the step resealed is see above-mentioned encapsulating method and step.
The utility model device and method is adopted to seal to cable duct the benefit reached as shown in the table:
