СПОСОБ И УСТРОЙСТВО ЗАЩИТЫ ОТ НЕДОПУСТИМЫХ ПЕРЕПАДОВ ДАВЛЕНИЯ В ДЕКОМПРЕССИОННОЙ КАМЕРЕ

摘要

FIELD: physics. ^ SUBSTANCE: air under regulated excess pressure is supplied to the chamber along the input channel through a reducing device from a source of compressed air. Using a system of valves, relief pressure is established and air is let out through the output channel to the relief system. When there is a pre-calculated positive or negative fall of regulated pressure inside the decompression chamber, the input and output valves are closed simultaneously using a device for protection from prohibitive pressure fall. ^ EFFECT: automatic blocking off of input and output air channels of a chamber when there is a sharp pressure fall inside a chamber and more reliable operation. ^ 2 cl, 3 dwg
