Abstract
The utility model discloses a ball valve. The ball valve comprises a big valve body, a small valve body, a ball body and a fluid channel formed in the big valve body and the small valve body, wherein valve seats are arranged in the big valve body; the ball body is arranged on the valve seats; a channel is formed in the middle of the ball body; elastic sealing pieces are arranged between the ball body and the valve seats; a padding chamber is formed above the big valve body; a valve rod is arranged in the middle of the padding chamber; the bottom end of the valve rod is in transmission connection with the ball body; a handle is fixedly connected to the top of the valve rod; padding is filled in the padding chamber and compacted through a padding gland; a valve port gasket is formed on connected and matched surfaces of the big valve body and the small valve body; and flange disks are arranged on the outer walls at holes of the fluid channel. The ball valve has the advantages that the elastic sealing pieces are arranged between the ball body and the valve seats and have the characteristics of aging resistance and elasticity, so that a phenomenon that inner leakage of the valve bodies can be avoided.
Description
Technical field
The utility model relates to valve and manufactures field, particularly a kind of ball valve.
Background technique
Valve is must indispensable controlling component on pipeline transportation device, and its action value is great, but the valve under prior art, the valve internal spheroid of particularly manually controlling contacts defective tightness with valve seat, the generation internal leakage.
