Pressure vessel with double-layer sealing structure

The utility model relates to the field of pressure vessels, in particular to a pressure vessel with a double-layer sealing structure, which comprises a vessel body, the right side of the vessel body is fixedly connected with an inlet pipe, the inside of the inlet pipe is movably connected with a conical pad, and the surface of the conical pad is fixedly sleeved with a rubber sleeve. The outer wall of the rubber sleeve is in lap joint with the inner wall of the inlet pipe. The surface of the inlet pipe is sleeved with the sealing cover, then the locking rod is rotated, the left end of the locking rod is connected with the threaded hole in the surface of the conical pad, the conical pad drives the rubber sleeve to be tightly attached to the inner wall of the inlet pipe in the rotating process of the locking rod, at the moment, the sealing cover is attached to the right end of the inlet pipe, the double-layer sealing effect is achieved, and the sealing performance is improved. After the conical pad with the rubb
