FIELD: machine building.
SUBSTANCE: proposed valve 10 has body 12. Said body has valve chamber 18 with valve seat 30 and valve stem 20 with flow channel 22, 24. Valve stem 20 is arranged inside valve chamber 18 ahead of valve seat 30 to rotate about rotational axis A to control fluidised flow flowing through valve 10. Valve comprises spring devices to displace valve stem 20 toward valve seat 30 perpendicular to said rotational axis A to provide for tight contact between stem and seat. Said spring devices comprise at least one cantilever spring 40 mounted in gap 42 opposite valve seat 30. Said spring 40 is secured inside valve body. Spring tail part stays in contact with cylindrical pressure surface to displace valve stem 20 to valve stem 30. Besides valve comprises coal dust injection system for shaft furnace that incorporates above described valve.
EFFECT: higher tightness of valve and furnace irrespective of working conditions and accumulation of finely-dispersed inclusions.
