Abstract
A reusable inflatable cable duct sealing device comprises a sealing bog body, wherein an inflation device which is an inflation nozzle is arranged on the sealing bag body, the inflation nozzle comprises an inner nozzle and an outer nozzle, grooves are formed in both the inner nozzle and the outer nozzle, through holes are formed in the grooves of the inner nozzle and the outer nozzle, the diameter of a top groove in the inner nozzle is smaller than that of a bottom groove, the inner nozzle and the outer nozzle are connected through a bolt, a sealing column which is a circular-truncated-cone-shaped column is arranged in the outer nozzle, the diameter of the largest circle of the circular-truncated-cone-shaped column is larger than or equal to that of the groove of the outer nozzle. During working, the sealing bag is inflated, the circular-truncated-cone-shaped column in the outer nozzle is stressed towards the sealing bag under the air pressure during inflation, the through holes are kept unlocked, inflation is realized, when the sealing bag is full, the air pressure inside the sealing bag is higher than that outside the sealing bag, the circular-truncated-cone-shaped column is stressed from outside to inside, the through holes are closed, inflation is finished, and the sealing bag is completely expended to cover cables.
Description
Art
The present invention relates to a kind of cable inflatable pipeline sealing device repeating Reusability.
Background technique
Cable protection is very important; prior art is for adopting the material shutoff raceways such as cement; the shortcoming of this way can lose waterproofing effect because expanding with heat and contract with cold cracking between material and pipeline, and 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.
Summary of the invention
The material shutoff raceways such as cement are adopted in order to overcome prior art.The shortcoming of this way can lose waterproofing effect because expanding with heat and contract with cold cracking between material and pipeline, and 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.The invention provides a kind of cable inflatable pipeline sealing device repeating Reusability, not only waterproof and anticorrosion, and install fast and convenient disassembly.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of cable inflatable pipeline sealing device repeating Reusability, and include sealing package body, sealing package body is provided with inflator, and described inflator is charging air inlet.Described charging air inlet comprises Nei Zui and Wai Zui, Nei Zui and Wai Zui is equipped with groove, outer mouth groove and interior mouth groove are provided with through hole, outer mouth top groove diameter is less than bottom groove diameter, interior mouth groove diameter is greater than outer outspoken footpath, and Nei Zui connects with outer muzzle and coordinates, and is provided with seal arrangement in described outer mouth groove, described seal arrangement is sealing column, and described sealing column is frustoconic shape.
The invention has the beneficial effects as follows: have wide range of applications, invent the life-span long, remove easy, install quick and convenient, can Reusability be repeated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 be charging air inlet analyse schematic diagram;
Fig. 3 is operating diagram of the present invention;
Fig. 4 is the structural representation of charging air inlet.
Embodiment;
Repeat a cable inflatable pipeline sealing device for Reusability as Figure 1-Figure 4, include sealing package 7 body, sealing package 7 body is provided with inflator.Inflator is charging air inlet 8, charging air inlet 8 is divided into interior mouth 10 and outer mouth 5, and interior mouth 10 and outer mouth 5 are all provided with groove 6, and outer mouth groove and interior mouth groove are provided with through hole 11, interior mouth pushes up 1 groove diameter and be less than bottom 2 groove diameter, outer mouth 5 inserts interior mouth groove and links together.Be provided with sealing column in outer mouth 5, described sealing column is round platform post 3, and on round platform post 3, greatest circle diameter is more than or equal to outer mouth groove diameter.Described round platform post is that flexible glue is made.During work, inflation is implemented to sealing package 7, in inflation China and foreign countries mouth 5, round platform post 3 is bullied and is pressed in sealing package stressed, keeps unimpeded enforcements of through hole 6 to inflate, when inflation reaches full, sealing package 7 air pressure inside is greater than sealing package 7 external pressure, and round platform post 3 is stressed from inside to outside, and through hole 6 is closed, inflation terminates, and sealing package 7 is turgor parcel cable 9 completely.
