Further, when the mouth of pipe of sealing plate 4 and sealing plug 7 to pipeline 1 carries out the shutoff, at this moment rotate sealing plate 4 surface mounting's rolling disc 901 earlier for rolling disc 901 drives screw post 902 and rotates, and then makes shift ring 904 remove to the direction that is close to elasticity gasbag 8, carries on spacingly to the elasticity gasbag 8 that is in the shriveled state.
Further, open control flap 11, aerify to the inside of elasticity gasbag 8 through gas-supply pipe 10, and because the limiting displacement of shift ring 904 for elasticity gasbag 8 forms a bowl-shaped structure, and explosion suppression ware is installed to sealing plug 7 one end, and when cutting off the gas of pipeline 1 inside, explosion suppression ware spun powder, powder and water reaction form acidic liquid can fall inside the bowl-shaped structure that elasticity gasbag 8 formed, and then corrode sealing device with preventing acidic liquid.
Finally, when not needing to use, through dwang 161 once more for dwang 161 drives first bevel gear 162 and rotates, thereby makes the inside threaded rod 15 of pegging graft of second bevel gear 163 rotate, makes first solid fixed ring 2 remove to the direction of keeping away from the solid fixed ring 3 of second, and then makes closing plate 4 remove the inside of pipeline 1, and is easy and simple to handle.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
