Title:
GAS-PERMEABLE MEMBRANE-USED APPARATUS
Document Type and Number:
Japanese Patent JP3697517
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a gas-permeable membrane-used apparatus having a special means which does not hinder the operation of the apparatus when operated normally but can restrain a large quantity of gas from being released when a gas-permeable membrane collapses.
SOLUTION: This gas-permeable membrane-used apparatus is provided with a supply chamber and a permeation chamber which are isolated from each other by the gas-permeable membrane. A pressure reducing valve is arranged on the downstream side of an outlet of the permeation chamber and a flow rate control means consisting of a resistive element is arranged on the downstream side of the pressure reducing valve. The valve-outlet pressure of the pressure reducing valve is set higher than the valve-inlet pressure when the apparatus is operated normally.
