Description
Technical Field
The utility model relates to the technical field of ball valves, in particular to a fireproof and antistatic ball valve.
Background
The ball valve, the opening and closing piece (ball) is driven by the valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline.
Chinese patent CN206874871U discloses an antistatic fireproof ball valve, which comprises a valve body, a valve cover, a valve seat, a ball valve core, a valve rod and a handle, wherein an antistatic device is arranged between the valve body and the ball valve core, the antistatic device comprises an electrostatic guide block which is arranged in the valve body and elastically pushes the electrostatic guide block which is movably contacted with the ball valve core, and the valve body guides the static electricity on the surface of the ball valve core through the electrostatic guide block.
The static electricity guide block and the ball body are connected in a conduction mode through the spring, but the connection of the spring is not stable enough, the static electricity cannot be led out due to the fact that the static electricity guide block and the ball body are prone to shifting.
