Abstract
The utility model relates to an acid/base salt resistant fluorine-lined ball valve which comprises a large valve body; a small valve body is arranged at one side of the large valve body; the large valve body is internally provided with a ball body provided with a valve rod; the ball body is provided with a through hole ball body; a locating piece and a seal ring are arranged at the part of the through hole ball body in contact the inner wall of a fluid access channel; two stuffing boxes are respectively arranged at the upper end and the lower end of the ball body provided with the valve rod; each stuffing box is fully filled with a filler cushion, a middle filler and an upper filler cushion; the stuffing box arranged at the upper end of the ball body provided with the valve rod is pressed by a packing gland and a gland flange; the gland flange is fixedly connected to the large valve body by screws; and the upper end of the valve rod of the ball body is fixedly connected with a handle. The acid/ base salt resistant fluorine-lined ball valve has the beneficial effects that fluoroplastic is taken as a liner on the wall of the inner cavity of the fluid channel of the acid/base salt resistant fluorine-lined ball valve, so that the corrosion of acid and base salts or other fluid can be effectively prevented, the sealing performance is good, and the service life is long.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of lining fluorine ball valve.
Background technique
There is poorly sealed defective in lining fluorine ball valve in the market, might cause serious leakage, and the resistance when opening switch is big, the shortcoming that physical life is short.
The model utility content
To the deficiency of existing technology, the utility model provides a kind of lining fluorine ball valve of antiacid alkali salt.
To achieve these goals; The utility model solves the technological scheme that its technical problem adopted: a kind of lining fluorine ball valve of antiacid alkali salt; Comprise big valve body, be provided with little valve body, be provided with the spheroid of valve rod in the big valve body in a side of big valve body; Spheroid is provided with the through hole spheroid and fluid access way inwall contacting point is provided with location piece and seal ring; Be provided with Stuffing box in described upper end and the lower end that has the spheroid of valve rod, Stuffing box is by down Packing seat, middle filler and go up Packing seat and fill fullly, and the filler that is positioned at the spheroid upper end that has valve rod presses through filler gland and hold-down grid.
Described hold-down grid is to be connected on the big valve body through screw.
The described valve rod upper end that has the spheroid of valve rod is fixedly connected with handle.
Described big valve body, little valve body are cast bodies.
The beneficial effect of the utility model: fluoroplastic are arranged as lining on the fluid passage internal chamber wall of the lining fluorine ball valve of this antiacid alkali salt that the utility model provides, the corrosion of fluid such as antiacid alkali salt effectively, sealability is better, and physical life is longer.
