AIR BLEEDING GAS-LIQUID SEPARATION MEMBER FOR PIPE LINE

摘要

PPROBLEM TO BE SOLVED: To provide an air bleeding gas-liquid separation member for a pipe line, capable of deterring a liquid such as water from being permeated, and capable of bleeding only gas such as air, by attaching it to an air collection part provided in the pie line, as to an air bleeding device installed in the pipe line for a water line pipe or the like. PSOLUTION: A gas-liquid separation membrane is constituted of a gas permeable membrane provided by generating a craze in a water-repellent fluoro resin film or the like, to prevent a water droplet generated in a membrane face of the gas-liquid separation membrane from being deposited. The deposition of the water droplet not only worsens remarkably gas permeability of the gas-liquid separation membrane, but also gets to a factor of freezing in a severe winter season, and an air bleeding function is impaired thereby.
