The invention relates to a brake cylinder protection assembly which comprises a safety valve and a ventilation valve which are installed on a brake cylinder body shell. The safety valve comprises a valve element with a center hole, through holes communicated with the center hole are formed in the side wall of the valve element, a supporting ring mounting part is arranged on the outer surface of the valve element between the through holes, a supporting ring and a dustproof ring are arranged on the supporting ring mounting part in a sleeving mode and arranged in a protective sleeve, the valve element extends out of the protective sleeve and is fixed through a spacer ring, and the opening directions of the protective sleeve are perpendicular to each other; the ventilation valve comprises a ventilation valve body, the small end is connected with the cylinder body shell, a sealing valve element and a positioning ring are arranged in the large end, a ventilation hole is formed in the positioning ring, and the ventilation valve body is sleeved with a rubber protection sleeve. The problem of sealing leakage caused by the fact that steam enters the brake cylinder in extreme weather is solved, and normal operation of a train is ensured.
