Abstract

The utility model relates to an operating mechanism for opening and closing a valve, which is composed of a disk type permanent-magnet magnetic coupler arranged at the position of an operating wheel of a traditional valve. The coupler is composed of an inner magnetic disk, an outer magnetic disk, and an isolated disk which is arranged between the inner magnetic disk and the outer magnetic disk, wherein the inner magnetic disk and the outer magnetic disk are coaxial; the interior of the valve and the inner magnetic disk of the coupler are completely isolated from the outside by the isolated disk. When the outer magnetic disk of the coupler is rotated, the inner magnetic disk can move along with the outer magnetic disk under the action of magnetic field force, so that the valve can be opened and closed without leaking outwards. The operating mechanism has the advantages of simple structure, easy manufacture and low cost. The valve which adopts the operating mechanism is especially suitable for inflammable pipeline systems, explosive pipeline systems and poisonous pipeline systems.
