Except sealing state, cylinder piston rod 5 continues to decline, and internal buckle block 2 and internal buckle connecting plate 3 also continue to be rotated down, and makes internal buckle block 2
After gathering is parallel with vertical petroleum pipeline 1, stop the decline of cylinder piston rod 5；Finally, on the sagging flange 11 of liquid entrucking oil filling riser
It rises, external cylinder internal buckle sealing device is separated with rising and tank car mouth 6, and is parked in designated position together.
It is of the present invention a kind of for the big lid of tank truck external cylinder internal buckle sealing, simple in sturcture, ingenious in design, production
Low in cost, easy to operate, using effect is significant, and durable, long-time service is hardly damaged, and improves lid to the close of oil tank
Seal effect, it is therefore prevented that the pernicious gas in oil tank is directly discharged into air, reduces fire hazard, solves the filling generation of oil product
Petroleum vapor recovery problem, while environment can be protected to be conducive to the health of people.
