Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out clearly the technical solution in utility model embodiment
Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of resistance for natural gas line rapid rush-repair
Device of air, including telescopic rod 2 and sizing bar 3, telescopic rod 2 is mounted on the inside of sizing bar 3, and one end of telescopic rod 2 extends to
Be formed bar 3 top, be formed bar 3 two sides outer wall on be mounted on shell 14, be mounted on bullet on the two sides outer wall of telescopic rod 2
Spring 13 is formed on the outer wall of bar 3 and is separately installed with chock flap a7 and chock flap b8 in being arranged above and below, chock flap a7 and chock flap b8
Outer wall on be mounted on explosion-proof air cushion 9, by installing two chock flaps, and inflatable explosion-proof air cushion is installed outside chock flap
9, after installing chock flap to pipeline, it can be filled with suitable nitrogen into explosion-proof air cushion 9, so that explosion-proof air cushion be made to be close to pipe
Road, to achieve the purpose that choke, the choke effect of the device, chock flap a7 and chock flap b8 has been effectively ensured in two layers of chock flap
