FIELD: gas industry.
SUBSTANCE: invention relates to the field of gas purification from impurities, mainly from various types of liquid media, and can be used in gas separators with the organized removal of liquid from the separation zone. Check valve for fixation at the lower end of the drain pipe of the gas separator includes a housing, a stop plate movably installed by means of rings on the housing, and a plate lifting limiter. Check valve is additionally equipped with two-arm lever movably installed on housing by means of rings, to which to one arm of which float is attached, and second arm is made in form of bracket to lift locking plate when float floats up.
EFFECT: invention allows improving operating efficiency of gas-liquid separator due to absence of pulsations in drain pipe of separator and reducing wear of moving parts of valve.
