Description
Technical field
The utility model relates to the metal sheathed cable field, particularly relates to a kind of tightness test device of metal sheath.
Background technology
In metal sheathed cable, must carry out the air-tight test of metallic sheath, need sealed at both ends with protective metal shell at the trial, and connect rain glass, by inflation, make the air pressure that reaches certain in the protective metal shell, after the placement by a period of time, check whether air pressure has to diminish, to determine whether this protective metal shell leaks gas.When testing, adopt the mode of argon arc welding to carry out the effect that welded seal just can reach regulation usually in the past, but in practical operation, seemed relatively trouble.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of tightness test device of metal sheath, makes that operation is more easy.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of tightness test device of metal sheath is provided, packoff and back packoff before comprising, packoff comprises pressing plate, sealing pressing mold, cable core sealing flexible glue circle and overcoat before described, and described pressing back-end is equipped with described sealing pressing mold; Be provided with described cable core sealing flexible glue circle in the described sealing pressing mold; Described cable core sealing flexible glue circle is enclosed in around the protective metal shell cable core; Described sealing pressing mold peripheral hardware has described overcoat; Described overcoat and described pressing plate interconnect; Described back packoff is identical with described preceding sealing device structure; The pressing plate hub head end of packoff links to each other with rain glass before described; The rear end, pressing plate center of described back packoff links to each other with the inflation interface.
Be provided with the pressing plate O-ring seal between described pressing plate and the sealing pressing mold.
Described pressing plate links to each other with described overcoat by follower bolt.
Packoff and back packoff all are fixed on the described protective metal shell cable core by set bolt before described.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model is by the sealing of the cable core in pressing plate crush seal pressing mold flexible glue circle, make its distortion and closely push with the protective metal shell cable core, and the sealing by the pressing plate O-ring seal makes the utility model reach good sealing effectiveness, the utlity model has simple to operate, can reuse, cost is low, the efficient advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present utility model relates to a kind of tightness test device of metal sheath, as shown in Figure 1, packoff and back packoff before comprising, packoff comprises pressing plate 2, sealing pressing mold 4, cable core sealing flexible glue circle 9 and overcoat 5 before described, and described sealing pressing mold 4 is equipped with in described pressing plate 2 rear ends; Be provided with described cable core sealing flexible glue circle 9 in the described sealing pressing mold 4; Described cable core sealing flexible glue circle 9 is enclosed in around the protective metal shell cable core 7; Described sealing pressing mold 4 peripheral hardwares have described overcoat 5; Described overcoat 5 interconnects by follower bolt 3 and described pressing plate 2; Described back packoff is identical with described preceding sealing device structure; Pressing plate 2 hub head ends of packoff link to each other with rain glass 1 before described; The rear end, pressing plate 2 center of described back packoff links to each other with inflation interface 10.Be provided with pressing plate O-ring seal 8 between described pressing plate 2 and the sealing pressing mold 4, can make the sealing of whole device more good by pressing plate O-ring seal 8.Packoff and back packoff all are fixed on the described protective metal shell cable core 7 by set bolt 6 before described, so can effectively prevent coming off and displacement of locking apparatus, reach better sealing effectiveness.
Using method of the present utility model is as follows: whole device is fixed on the protective metal shell cable core 7, be positioned at the cable core sealing flexible glue circle 9 of sealing pressing mold 4 by pressing plate 2 extruding, make it that deformation take place, closely push with protective metal shell cable core 7, connect rain glass 1 and inflation interface 10, inflate to protective metal shell cable core 7 by inflation interface 10, make and reach certain air pressure in the protective metal shell cable core 7, after the placement by a period of time, check whether air pressure diminishes, to determine whether this protective metal shell cable core 7 leaks gas.
Be not difficult to find, the utility model is by the sealing of the cable core in pressing plate crush seal pressing mold flexible glue circle, make its distortion and closely push with the protective metal shell cable core, and sealing by the pressing plate O-ring seal, make the utility model reach good sealing effectiveness, the utlity model has simple to operately, can reuse, cost is low, the efficient advantages of higher.
