FIELD: fire engineering.
SUBSTANCE: flame arrester contains chamber (1) which is connected with tubular member (2) through truncated cone (3). In tubular member (3) transmitter (3) is located which transmitter is adjusted to transit product speed and controls the locking device of compressed gas source (5) which is connected to pneumatic actuator (7) via pneumatic path. Pneumatic actuator (7) is connected with valves (9) and (10) through linkage (8). Tubular member (2) is equipped with propelling ring diaphragms (11).
EFFECT: high-speed conditions for transit product movement and flow resistance minimization creation, flame arrester allows to obtain reliable functional result.
