COMPRESSION BYPASS VALVE AND METHOD FOR CONTROL THEREOF (OPTIONS) Russian patent published in 2018 - IPC E21B34/12 F16K15/02 

FIELD: mining.

SUBSTANCE: group of inventions refers to mining and can be applied in compression bypass valves. Compression bypass valve comprises a body of the main section. Body of the main section contains an opening of the main section. Body contains a sleeve for sealing rings. Sleeve for the O-rings contains a sleeve opening for the O-rings and O-rings installed on both sides of the sleeve hole for the O-rings. Sleeve for the sealing rings is configured to prevent rotation with respect to the body of the main section, and is also movable relative to the body of the main section between the open position of the sleeve for the sealing rings and the closed position of the sleeve for the sealing rings. Sleeve hole for the O-rings is aligned with the opening of the main section when the sleeve for the O-rings is in the open position of the sleeve for the O-rings, the opening of the sleeve for the sealing rings is hermetically sealed from the opening of the main section by means of O-rings, when the sleeve for the sealing rings is in the closed position of the sleeve for the O-rings.

EFFECT: technical result is to increase the efficiency of the compression bypass valve.
