Antiseep oil valve for high voltage electrical apparatus

The utility model relates to a valve body, in particular to an antiseep oil valve for a high voltage electrical apparatus, which aims to solve the technical problem of providing an antiseep oil valve for a high voltage electrical apparatus for preventing insulating oil seepage and avoiding sample contamination. The antiseep oil valve comprises a transition piece, a plug and a valve core; wherein the valve core is fixed in the cavity of the transition piece, the plug is fixed at the tail end of the wall of the cavity of the transition piece, a rabbet is formed on one side of the plug in contact with the transition piece, and a seal ring is fixed in the rabbet; a protective cap is also covered on the outer wall of the transition piece. By forming the rabbet on the plug, the seal ring can be prevented from being extruded and deformed and cracking when the plug is opened; by covering the protective cap on the outer wall of the transition piece, the cleanness of the plug is ensured, and the contamination to the in
