METHOD FOR CONTROLLING RELEASE OF COMPRESSED FLUID Russian patent published in 2021 - IPC B05B9/01 B05B1/30 F16K31/385 

FIELD: engineering.

SUBSTANCE: invention relates to a compressed fluid release control apparatus for controlling the release of a compressed fluid. A compressed fluid release control apparatus for controlling the release of a compressed fluid, wherein the compressed fluid release control apparatus includes a valve chamber formed therein, wherein the valve chamber is located between a supply channel intended for supplying a compressed fluid and an outlet channel with an outlet a port intended for the release of a compressed fluid, and the valve chamber is equipped with a valve seat, the compressed fluid release control apparatus includes: a diaphragm valve intended for blocking or establishing communication between the supply channel and the outlet port by being set on or detached from the valve seat, wherein the diaphragm valve includes a pilot channel formed therein; a pilot chamber opening and closing valve intended for opening and closing the pilot chamber whereto the compressed fluid is introduced from the supply channel via the pilot channel; a body with a valve chamber, a pilot chamber and an outlet channel formed therein, equipped with a diaphragm valve and a pilot chamber opening and closing valve, and an opening and closing working element installed outside of the body and intended for opening and closing the pilot chamber opening and closing valve, wherein by opening the pilot chamber opening and closing valve thereby opening the pilot chamber, the diaphragm valve is separated from the valve seat, thereby establishing communication between the supply channel and the outlet channel, and when the pilot chamber opening and closing valve is closed or when the supply of the compressed fluid from the supply channel is terminated, the diaphragm valve is set on the valve seat, thereby closing the pilot chamber and blocking communication between the supply channel and the outlet channel.

EFFECT: high efficiency of removal of a powder.
