Pressurising lid lower end is equipped with disk spring, and the lower end of the disk spring is pressed about filling is symmetrically installed in the middle part of butterfly spring
Ring, the filling pressure ring are equipped with locator close to the one end in left side, and the lower right side of the locator is equipped with anti-static device.
Preferably, the valve seat is symmetrical about valve rod middle part, and quantity is at least four.
Preferably, it is connected by screw between the limited block and filling gland.
Preferably, the anti-static device includes electric conductor and spring, and the lower end of electric conductor is fixedly connected with spring.
Preferably, the locator includes that body and ring spring are held in top, and push up to hold and pass through hinge between body and ring spring
Chain link.
Preferably, the electric conductor be made of cap body, the body of rod and step column, and the cap body on the right side of movable connecting rod
Body, the body of rod top are fixedly connected with step column.
Technical effect and advantage of the invention: this has the ball valve of anti-static function, passes through the medium position peace in valve rod
Locator has been filled, ball valve is made to produce the function of antistatic, anti-static device has been equipped with by the lower right side in locator, into one
Step improves the effect of antistatic.The ball valve with anti-static function, by being mounted with locator and two kinds of anti-static device
Equipment, it is ensured that the anti-static effect of ball valve improves service performance, avoids electrostatic and excessively generates the wind that spark causes fire
Danger.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is the structural diagram of the present invention, a kind of ball valve with anti-static function, including main valve body
1 and valve rod 3, the 1 middle part left and right sides of main valve body is mounted on valve seat 2, and 3 upper end of valve rod is connected with handle 5, institute
It states 5 downside of handle and limited block 7 is installed about 3 central symmetry of valve rod, 7 lower end of limited block is fixedly connected with filling gland 8,
It is connected by screw between the limited block 7 and filling gland 8,8 lower end of filling gland is equipped with disk spring 11, described
The lower end of disk spring 11 is about filling pressure ring 9 is symmetrically installed in the middle part of butterfly spring 11, the filling pressure ring 9 is close to left side
