[embodiment]
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1 and Figure 2, a kind of gas-filled type power pipe water-tight equipment described in this embodiment, it comprises a gas formula sealing bag body, described gas formula sealing bag body comprises a sealing bag 1, described sealing bag 1 is made up of soft metal surface 11 and some polymer material layers 12, described sealing bag 1 is flat-shaped body, is provided with cavity in it; The surperficial both sides of described sealing bag 1 are compounded with and the high temperature resistant waterproof film 2 sealing bag 1 and formed integrative-structure; One end of described sealing bag 1 is provided with inflation inlet 3, the colloidal materials 4 of filling containing oneself in this inflation inlet 3.
Preferred as one of the present utility model, the soft metal surface (11) of described sealing bag (1) is provided with wearing layer.
Preferred as one of the present utility model, described sealing bag (1) inwall arranges and is coated with Waterproof glue line.
Operation principle of the present utility model is as follows: gas formula sealing bag body is made up of soft metal (being generally aluminium film) and layer high molecule material, both sides are with resistant to elevated temperatures waterproof film, when inflation, (gas be filled with is normal air, source of the gas can be common air compressor machine or 12V power supply inflator pump or carbon dioxide steel cylinder) air pressure is when reaching 45psi (3bar), both sides film can be close to inner-walls of duct and cable, arrives complete waterproof.Inflation gas port includes the colloidal materials that oneself fills, Leakage Gas when preventing gas-filled tube from extracting out.Pipeline inner cable is so just made to be adequately protected and seal.
The utility model in use, seals the carrying out of power pipe, carries out according to the following steps:
1), clean electric power inner surface of pipeline, the wet cloth of suggestion cleans;
2) protection sheet of inflatable seal bag outside, is torn off, the inflatable seal bag of flat-shaped body is rolled and the sealing bag rolled is sent into cable, sealing bag is provided with one end of inflation inlet towards pipeline oral area, along cable by the sealing bag rolled with the form sliding inlet pipe road unreeled, until entire volume sealing bag 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, sealing bag need be extended in pipeline;
4), by one end of air tube insert inflation inlet, the air tube other end is communicated with source of the gas;
5), to sealing bag inner chamber inflate, until the air pressure in sealing bag reaches 3.Mpa, make the pressure in sealing bag keep this numerical value to be no less than 30 seconds, pull out gas-filled tube, power pipe has sealed.
If the utility model needs recovery cable, then the method for dismounting of sealing bag and step as follows:
1) inflation inlet is inserted in one end of air tube, make the gas light leak of sealing bag, continue with screwdriver, sealing bag to be separated with power pipe wall;
