ABSTRACT:
An air inlet valve subassembly for use on a particle fuel burning furnace includes a manifold tube and a hollow spout mounted to an outer end of the manifold tube. The spout has an outer rim defining a valve opening and the manifold tube is adapted to be mounted at its inner end to the furnace to provide a passageway for communicating air from the valve opening into the furnace. A valve flap is mounted adjacent to the spout for pivotal movement toward and away from the spout between closed and open positions in which the manifold tube passageway is closed and opened to the communication of air. For sealing the valve opening, a generally planar, resiliently flexible disk with an annular ring of gasket material adhered thereon is provided. The disk, preferably made of stainless steel material, is removably mounted to the valve flap at the respective centers thereof with its outer side facing toward the flap and its inner side facing toward the spout rim. The gasket material ring is affixed on the inner side of the disk and is capable of contacting the spout rim for providing an air seal between the disk and the spout rim when the valve flap is at its closed position. At least one wedge-shaped shim is insertable between the valve flap and the outer side of the planar disk to deflect the disk periphery and cause matching of the gasket material contour with the contour of the spout rim. An actuator is linked to the valve flap and is operable to cause movement of the flap between its closed and opened positions.
