Steam-water separator enabling expansion energy release

The invention relates to a steam-water separator enabling expansion energy release in the field of steam conveying auxiliary equipment. A liquid inlet of the steam-water separator is formed in an upper cylinder, a liquid outlet of the steam-water separator is formed in a lower cylinder, the upper cylinder and the lower cylinder are isolated through a middle part, a microporous partition plate is horizontally arranged in the upper cylinder, and the liquid inlet is formed above the microporous partition plate. A top cover is arranged at an upper opening of the upper cylinder; a plurality of positioning nuts are arranged on the top cover, adjusting rods are in threaded connection with the positioning nuts, and valve elements are arranged at the lower ends of the adjusting rods. A plurality ofthrough holes communicated with the upper cylinder and the lower cylinder are formed in the middle part, valve seats are fixedly mounted at upper openings of the through holes through positioning sleeves, the adjusting rods
