摘要（英）：

The utility model belongs to electric power accessories, and particularly relates to a sealed transformer stop valve with vacuum conical surfaces. A valve body seal conical surface (7-1) is arranged in an inner cavity of a valve body (7) and provided with a valve plate (9), a valve plate seal conical surface (9-1) is arranged on the valve plate (9), the valve body seal conical surface (7-1) is connected with the valve plate seal conical surface (9-1) in a contact mode, a valve cover (5) is in threaded connection with a valve rod (6), the portion between the valve rod (6) and the valve cover (5) is filled with filler (4) for sealing, a gland (3) is arranged on the filler (4) in a pressing mode and installed on the valve rod (6) in a sleeving mode, the gland (3) and the valve cover (5) are fixedly locked through a second fixing screw (13), and a hand wheel (2) is arranged at the upper end of the valve rod (6) in a sleeving mode and fixedly locked through a first fixing nut (1). The sealed transformer stop valve with the vacuum conical surfaces is simple in structure, convenient to machine, resistant to corrosion, good in seal performance, long in service life and easy to operate and saves time and labor when opened or closed.
