AUTOMATIC GAS RELEASE VALVE Russian patent published in 2016 - IPC F16K24/04 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a gas release valve. Automatic gas release valve comprises a body equipped with an automatic gas release valve system. Automatic gas release valve system comprises a normally closed gas discharge valve having a control chamber and equipped with an inlet channel for a fluid medium. Automatic valve unit has an inlet channel, which is hydraulically connected to the body, and an outlet channel, which is hydraulically connected to the control chamber, and can selectively generate a flow pulse in the control chamber to bring the gas discharge valve to its open position. Herewith the automatic valve can move between the closed and the open positions depending on the fluid level in the body. Automatic valve unit is equipped with a flexible closing partition attached at one end to the body and on the opposite end - to an element displacing the partition. Displacement of the partition displacing element downwards causes gradual separation of serial transverse parts of the flexible closing partition to open the outlet channel towards the open position of the automatic valve.

EFFECT: invention is aimed at higher reliability of the gas release valve.
