Title:
SPLIT-TYPE BLADE, FLUID DRIVE DEVICE AND FLUID DRIVE PROPORTIONAL MIXER
Document Type and Number:
WIPO Patent Application WO/2022/057493
Kind Code:
A1
Abstract:
A split-type blade (10), a fluid drive device (1) and a fluid drive proportional mixer. The split-type blade (10) is used as a component of the fluid drive device (1) to convert pressure energy of fluid into mechanical energy. The split-type blade (10) comprises: one or more push rods (11), each push rod (11) being suitable for being arranged on a rotor (20) of the fluid drive device (1) in a radially slidable manner; and two valve plates (12), the two valve plates (12) being respectively mounted in parallel at two end portions (111) of the push rods (11), and each valve plate (12) extending outwards along the push rods (11) to form the split-type blade (10) having a running-through push rod structure. In this way, when the split-type blade (10) drives the rotor (20) to rotate under the effect of a fluid, the push rods (11) of each split-type blade (10) slide in a radial direction relative to the rotor (20), so that an outer edge portion (121) of each valve plate (12) can always be in contact with an inner wall (31) of a stator (30) of the fluid drive device (1), facilitating the reduction of liquid leakage of the fluid drive device (1).
