| description | The invention belongs to the technical field of valves, and particularly relates to a high-precision flow proportional valve. The high-precision flow proportional valve comprises moving iron, static iron, a coil and a shell. The shell is provided with a mounting through hole, an air inlet and an air outlet, wherein the air inlet and the air outlet are both communicated with the mounting through hole. A first internal thread is arranged on the inner wall of the mounting through hole, a first external thread matched with the first internal thread is arranged on the static iron, and the static iron is mounted in the mounting through hole through the first internal thread and the first external thread which are in threaded connection; the coil is mounted in the mounting through hole; the moving iron and the static iron are inserted into an inner hole of the coil; an annular protruding part extending towards the moving iron is arranged on the inner wall of the air inlet, and an adjusting gap is formed between the |
