Zusammenfassung:	The utility model discloses a high-pressure sealing device which is used for sealing an oil hole or a water hole in a circular-arc face or a cranked face. The high-pressure sealing device comprises a rubber gasket arranged at one end of a spindle shaft which extends into the oil hole or the water hole. The spindle shaft is further provided with a propping sleeve in contact with the rubber gasket. A nut is arranged at the tail portion of the propping sleeve and is tightly screwed with the propping sleeve. The high-pressure sealing device is simple in structure, reasonable in design, convenient to operate, low in requirement for machining precision of the hole to be sealed, simple to maintain, easy to manufacture and popularize, and also can be used for sealing inspection of tube section parts.
