Abstract
The utility model provides a pneumatic compression self-locking tank gas recycling sealing device at top of a train. A rubber sealing gasket is arranged above a tank opening. A bottom buckling mechanism is arranged in the tank opening. A vertical pipe liftable cylinder is arranged internally. The vertical pipe liftable cylinder drives a vertical pipe to connect with the buckling mechanism. A lock bolt and a bottom surface in the buckling mechanism and a guiding chute on the outer cylinder are connected through a sliding mechanism. When the vertical pipe drives the buckling mechanism to move upward, the lock belt horizontally expands and upwards compresses the tank wall, thereby providing a stable and reliable compression force for the upper rubber sealing gasket. The compression force only acts between the sealing cover and the tank opening. The rigidity of a crane tube and sediment of a tank locomotive have little effect on the compression force. Furthermore the generated compression force is greatly larger than the pressure generated by the gas. Therefore reliable sealing effect is realized. Compressing and releasing of the sealing device are finished by a pneumatic assembly. The pneumatic compression self-locking tank gas recycling sealing device is adapted for sealing various kinds of tank openings of train tank locomotive, and simple operation is realized. The pneumatic compression self-locking tank gas recycling sealing device can be used for performing sealed recycling on volatile oil and gas in oil refineries, oil conveying fields or chemical organizations or loading chemical medium into top part of the train tank locomotive.
