The invention discloses a valve element mechanism of a parallel double gate valve. The valve core mechanism of the parallel double gate valve comprises an outer frame, a screw rod, a vibration reduction device and a balance film, the vibration of a flashboard is absorbed and consumed by arranging the vibration reduction device, a solution of combining a vibration reduction spring and a buffer sealing ring is adopted by a buffer mechanism, by means of the characteristic, impact borne by a valve rod and the flashboard in a high-speed flowing state of fluid in a valve body is relieved when transmitted to the valve rod, the situation that the valve rod and the flashboard bear too large rigid impact and accordingly the performance is affected is avoided, and the beneficial effects that vibration reduction can be conducted at the upper end of the flashboard, and therefore the service life of sealing faces of the flashboard and a valve seat is prolonged is achieved, due to the design of a convex ring on a combined s
