(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a ball valve prevent static valve rod, including valve body, conductive spring and steel ball, the shaping of valve body upper end middle part has the installation high platform, it is connected with the valve rod to rotate on the installation high platform, it has the valve ball to peg graft in the valve rod bottom, the welding has on the valve rod lateral wall conductive spring, the welding of conductive spring one end has the steel ball.
By adopting the technical scheme, the valve rod, the valve ball and the valve body are always kept in ground conduction through the design of the conductive spring and the steel ball, so that static electricity generated by the ball valve in the opening process can be smoothly guided into the ground, a fire disaster caused by igniting a flammable medium due to static ignition is avoided, and the use safety of the valve is ensured.
Furthermore, the steel ball is always in contact with the valve body and the valve ball.
By adopting the technical scheme, the valve rod, the valve ball and the valve body can be ensured to be always kept smooth to the ground.
Furthermore, a fixed sleeve is fixed on one side in the valve ball in a clamping and pressing mode, a valve seat is formed between the fixed sleeve and the valve body, and a sealing ring is arranged on the valve seat.
By adopting the technical scheme, the reliable installation and sealing of the valve ball can be realized.
Furthermore, the valve body and the fixed sleeve both adopt hollow structures.
By adopting the technical scheme, the normal circulation of the medium can be realized.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
for solving the valve rod on the current ball valve often can lead to the medium to be lighted when the valve rod is opened and close untimely because of the static derivation on the valve rod, thereby cause the conflagration, reduce valve safety in utilization problem, the utility model discloses a design of conductive spring and steel ball for remain throughout between valve rod, valve ball and the valve body and switch on to ground, thereby can be with the ball valve open the smooth leading-in underground of produced static of in-process, avoid igniting because of static is struck sparks and easily fire the medium and cause the conflagration, ensure to be the security that the valve used.
