Safety Valve Steam Baffle Product Features
For boiler safety valves and exhaust valves, they can be regarded as a component of the pipeline. After acoustic processing internally, they can reduce the generation and transmission of noise, achieving a noise reduction of 20 to 30 decibels (A-weighted) at the outlet. This corresponds to a 60% or more reduction in loudness, with a noticeable effect on the subjective perception. When designing the exhaust muffler for safety valves, the following three aspects should be considered:
Post-muffling, it is necessary to avoid excessive noise, and the muffling level should meet the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
2. The muffler should be rust-proof, clog-resistant, and capable of withstanding high temperatures, pressures, and air flow.
3. The exhaust volume and backpressure of the silencer should be compatible with the smooth discharge of the safety valve exhaust gas flow.
The working principle of the new type of safety valve exhaust silencer
The new safety valve exhaust muffler utilizes a through-hole spray and resistance noise reduction principle. It replaces the micro-porous perforated plate design with a large-pore expansion control flow, ensuring the smooth exhaust of the safety valve. It incorporates multi-level perforated sound absorption and combines it with the resistive noise reduction principle. This allows steam sound waves to enter the numerous small holes of the porous sound-absorbing material, exciting the vibration of the porous material molecules. This converts sound energy into heat as it overcomes frictional resistance and viscosity, achieving an ideal noise reduction effect.
