The invention discloses a flexible silencer which comprises a termination
flange, a silencing internal hose, a silencing external hose, an
isolation layer, a sound absorbent lining and a composite hose. The flexible silencer is characterized in that: the silencing internal hose is densely equipped with a plurality of silencing holes, the external part of the silencing internal hose is covered with the external silencing hose; the silencing external hose is densely equipped with a plurality of silencing holes, a sound absorbent cavity is positioned between the silencing internal hose and the silencing external hose, a plurality of fixing rings are arranged in the sound absorbent cavity in interval, the external part of the silencing external hose is equipped with the
isolation layer, the external part of the
isolation layer is equipped with the sound absorbent lining, the external part of the sound absorbent lining is covered with the composite hose, and the silencing internal hose and the internal-circular connector of the termination
flange are fixedly connected; the silencing external hose, the composite hose and the connector of the external-circular turned-
edge connector of the termination
flange are fixedly connected mutually. The flexible silencer is made of the flexible material which can be bent, the sound
absorbent material and the reasonable
silence structure, the invention can be configured according to the environment condition, and has the advantages of low cost, good
silence effect and convenient installation.
