Zusammenfassung:	The utility model relates to a novel steam choking shaft gland for gas compressors. The steam choking shaft gland is composed of the seal of seal cavities and comb teeth. One seal cavity is positioned at the position adjacent to medium end and is capable of being poured with water vapor; two seal cavities which are mutually communicate and are simultaneously connected with the same air extractor are arranged at atmospheric air end. Only one air extractor is used. The utility model has simple structure, low manufacturing cost and reduced consumptive steam quantity and no technical medium atmospheric dilution. The utility model is suitable for compressors with lower pressure such as the catalytic cracking air compressors of oil refineries.
