電気帯電防止装置。[Claims for Utility Model Registration] (1) Static electricity for valves that ensures conductivity between the valve body and stem, and between the valve stem and the valve body, and prevents the valve body and stem from being charged. In an antistatic device, a through hole or a bottomed hole is bored in a required surface of a valve body, a valve stem, a valve body, etc., and the through hole or bottomed hole makes elastic contact with the side wall of the through hole or bottomed hole. An electrostatic antistatic device for a bubble, which is constructed by attaching a spring formed by bending a conductive wire for a spring to a through hole or a bottomed hole so as to elastically contact a member adjacent to an opening of the bubble. (2) The electrostatic charge prevention device for a valve according to claim 1, wherein a through hole is bored between two parallel surfaces of the connecting portion of the valve stem of the ball valve with the valve body. (3) The electrostatic charge prevention device for a valve according to claim 1, wherein a bottomed hole is bored in the outer peripheral surface of the flange of the valve stem of the ball valve.
