Description: Vent Silencers is used to prevent the noise that is emitted from safety valves and control valves at different temperature and pressure. They also can withstand the rapid release of large quantities, of steam, at very high pressure apart from attenuating the noise. The silencer is made up of concentric annular acoustic cylinders enclosed in a robust steel casing with one end closed with dished or flat end and the other end open to the atmosphere. The fluid enters the silencer through a diffuser from the bottom-closed end, passes through the annular space between the acoustic packing where it loses the sound energy and escapes to the atmosphere. A drainpipe at the bottom is used to drain any condensate formed during operation. A weather cowl for rain protection and bird screen are provided for the silencer as optional items. Support brackets are provided on the external casing for installation purpose. The material of construction for the silencer is decided based on the operating pressure, temperature and the operating fluid. Rust preventing coating or heat resistant aluminum paintings is done on the external casting depending on customers' requirements.
