To achieve these goals, the gland sealing device of a kind of nickel alloy ball valve designed by the utility model, comprise valve body, valve rod and the gland being arranged on valve rod outer end circle, it is characterized in that: described gland is the gland with interior hollow, the boss protruded to horizontal direction is processed with in this gland inner chamber, the upper surface of this boss is provided with the first seal ring from the bottom up successively, upper bearing (metal), blind nut and the second seal ring, and the first seal ring, upper bearing (metal), blind nut and the second seal ring are all installed between gland and valve rod, the lower surface of this boss is provided with back-up ring from top to bottom successively, 3rd seal ring and lower bearing, back-up ring, 3rd seal ring and lower bearing are arranged between gland and valve rod, the cylindrical of gland (1) is provided with the outside plane of orientation (11) in 180 ° of distributions, the inner side plane that outside this, plane of orientation is corresponding on valve body is formed locates load mechanism.
Preferably, the end face of the second described seal ring is provided with opening, and described opening and the adjacent both ends of opening are outwards oppositely launched to form lipped configuration.
Preferably, described gland is including but not limited to nickel alloy gland.
Preferably, the second described seal ring opening up.
Preferably, the upper-end surface end of described blind nut has the small sircle hole for dismounting.
The gland sealing device of a kind of nickel alloy ball valve that the utility model obtains, by adopting technique scheme, having reasonable in design, corrosion-resistant and high pressure, ensure that usability and the technology capability of product.
Accompanying drawing explanation
