METHOD FOR REMOVING DEPOSITS FROM DRAINAGE PIPELINES OF SHUTOFF VALVES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC B08B9/32 

Abstract RU 2801862 C2

FIELD: gas industry.

SUBSTANCE: invention can be used in the maintenance (inspection) of pipeline valves. A method for removing deposits from a drainage line of pipeline valves is disclosed. The method consists of separation of deposits into fine fractions. A device is connected for the works, as a result of which the liquid with pressure obtained from the operation of the device handle enters the drainage pipeline through the check valve and ball valve of the device discharge line. Connection through a tee connection to the condensate collection device allows to exclude the release of solid fractions with accompanying gas condensate into the environment and to technical devices located near the working area. A device for carrying out the removal of deposits to fine fractions and removal from the drainage pipeline is also disclosed.

EFFECT: technical result of the invention is operations for purging condensate and moisture before the release of clean gas.
