2. The pressure drop across the diffuser is selected based on the flow conditions of the media to offer a cost-effective silencer design. After the pressure is reduced, the medium is sent through a muffler for better noise performance. Design of our diffuser assembly is in compliance with asme section 8, division 1 standards. Depending on the size of the diffuser and the silencer muffler upto 70db of noise can be reduced. Typical applications for startup vent silencer include boiler blow down lines, air compressor vents and gas plant vents.
3. The safety valve is a device to avoid a dangerous build-up of pressure within a system that it is designed to protect. One should never forget that any redesign of the PSV system must not decrease the safety of the protected system. A safety valve is normally used with compressible fluids, whereas a relief valve is primarily used with incompressible fluids. What is a safety valve? How often, long and loud is its noise?
4. • While venting a safety valve, kinetic energy from the medium is converted into pressure waves with a high amplitude. • This effect causes, even at a low capacity or a low reduction of capacity of 1 to 2 bar, a sound pressure level of between 115 and 125 dB(A) at a distance of 1 metre from the opening, depending on the application. Operating principle:
5. • With large volumes, combined with high pressure drops (e.g. with safety valves) the sound pressure level at a distance of 1 metre could even elevate as high as the aforementioned 150/160 dB (A). • A silencer consists of a diffuser, an expansion chamber and an absorption chamber. In the diffuser and the expansion chamber pressure is reduced in several steps, independent of the initial pressure, to atmospheric pressure.
6. Three noise related criteria are suggested for PSVs, Noise received at the local community, Acoustic fatigue of the components and associated pipe-work, The possibility of hearing damage due to noise received by a worker who is 'close' to an actuated PSV. What criteria might be used in the evaluation of safety valve noise?
