ABSTRACT:
A magnetic-controlled valve for fluid pipelines. The valve comprises a sealed guide bushing accommodating an external magnetic ring movable along the outer wall thereof and an internal magnetic plug-stopper movable longitudinally therein. A valve body accommodates one or more stages of a valve plunger, and the internal magnetic plug-stopper is aligned and engaged with the plunger. Lifting the external magnetic ring will lift the internal magnetic plug-stopper through a magnetic force, thus lifting the plunger to open the fluid passage of the valve body. This forms a magnetic-controlled stop valve. In an alternate configuration, an external magnetic ring is rotated to rotate the internal magnetic ring (blocks) to bring a butterfly type valve plate into rotary motion through a connecting rod. The rod is provided with a stopper element connected to the internal magnetic ring, thus forming a magnetic-controlled butterfly valve.
