Abstract
A locked oil gas recycling sealing device at an automobile top comprises a vertical pipe and a sealing cover which is fitted with a top tank opening of a tank truck. The central part of the sealing cover is provided with a vertical pipe penetrating hole. A gas liquid phase cylinder is arranged above the sealing cover. The lower edge of the gas liquid phase cylinder is jointed with the upper surface of the sealing cover. The side wall of the gas liquid phase cylinder is provided with a gas phase pipe. The gas liquid phase cylinder is internally provided with a vertical pipe lifting cylinder. A cover plate cylinder is arranged below the sealing cover. The sealing cover is provided with a rubber sealing pad along the outer wall of the cover plate cylinder. A bottom buckling mechanism which is matched with the inner edge of the tank opening of the tank truck is arranged below the cover plate cylinder. An integrated cylinder is used for supplying power for driving a chassis lock belt mechanism of the sealing device to lift. The lock belt expands and blocks the bottom of a tank opening manhole cover from inside of the tank opening, thereby supplying a stable and reliable compression force for an upper rubber sealing member. The compression force is only exerted between the sealing device and the tank opening. Adverse factors of oil gas pressure in the tank truck and tank truck settlement can be overcome. The locked oil gas recycling sealing device at the automobile top has advantages of: high sealing reliability, simple operation and compact structure.
