Valve arrangement

摘要

A fabric filter valve arrangement (9) adapted for providing pulses of compressed gas to clean fabric filter bags (6) in a fabric filter (1). The valve arrangement (9) comprises a plunger (12) movable in relation to an edge (15) of a first end (16) of a pulse pipe (13). When the valve arrangement (9) is closed the plunger (12) abuts the edge (15) of the first end (16) of the pulse pipe (13) thus blocking the flow of compressed gas to the interior (13a) of pulse pipe (13). A sealing portion (19) of a sealing material is arranged at the plunger (12) and/or the edge (15) of the first end (16) of the pulse pipe (13).
