Abstract

This utility model discloses an intelligent hydraulic butterfly valve, including a butterfly valve body, a butterfly plate disposed inside the butterfly valve body, the butterfly plate being mounted on a valve stem, the top end of the valve stem penetrating through the outer wall of the butterfly valve body to the outer shell, a rotating handwheel being connected to the outer shell, a limiting component being installed on the outer wall of the outer shell, the limiting component being provided with an installation mechanism, the limiting component being fixed to the outer wall of the outer shell through the installation mechanism, the limiting component limiting the rotation of the rotating handwheel; by setting the limiting component, in the non-use state, the operator rotates the limiting groove inside the rotating handwheel to the upper end, and after loosening the pull rod, the return spring pushes the limiting rod to engage with the limiting groove to form a fixed position, which can effectively prevent the handwheel from rotating accidentally due to external impact.
