Abstract
In this paper is proposed and designed a kind of precise flow valve which adopts giant magnetostrictive material (GMM) as its actuator. The valve drives the spool movement through the GMM rod’s scalability and deformation under the magnetic field and effectively improves the displacement output by adopting a hydraulic proportional magnifying structure. The opening of the flow valve mouth is then controlled, realizing a precise control on the flow. After design and calculation, where the structure parameters of the valve are determined, a prototype is manufactured and an experimental platform is built as well. Tests prove that the flow control precision of the GMM precise valve designed in this paper reaches 18 mL/min.
