Micro-flow throttling device

Abstract

A micro-flow throttling device, comprising: a casing used for assembling; a throttling structure mounted inside the casing to form resistance to control a fluid flow, wherein the throttling structure comprises a first axial hole formed inside a fine threaded rod, a first radial hole is formed on one side of the first axial hole, a fine thread flow channel is mounted on one side of the first radial hole, and a second cavity is formed between the fine thread flow channel and a coarse thread flow channel; a regulating structure mounted on the casing and used for regulating the flow rate of the fluid; and a butt-joint structure mounted on the inner wall of the casing and used for performing disassembly and assembly limiting on the throttling structure.
