Valve exhaust muffler

one、Valve exhaustsilencerUsage and advantages

   Valve exhaust mufflerMainly used in power plants, chemical industry, and steel industryThermal power, cement, air separation, air compressorSafety valves and exhaust valves in the industrygasEffective noise reduction through emissions. Generally divided：Boiler drum safety valve exhaustSilencerExhaust steam of superheater safety valveSilencerReheater safety valve exhaustValve exhaust silencers such as mufflers, boiler ignition valves, and exhaust silencers。

    For boilerssafety valveAnd with the exhaust valve, it can be seen as a component of the pipeline. After acoustic treatment inside, it can reduce the generation and propagation of noise, making the outlet noise reduction reach35—45Decibel（ASound level), correspondingOn site noisereduce50%Above, subjective feelings have a significant effect. designvalveexhaust steamsilencerThe following three aspects should be considered:

       1、silencerThe noise reduction capacity can meet the requirements of the "Industrial Enterprise Noise Hygiene Standards"; 

       2、silencerExcessive noise should be avoided, and the airflow should be smoothly eliminated.

       3、silencerThe structural performance. (Reasonable size, low cost, long service life, etc.) 

However, some manufacturers use common multi-stage throttling and small hole injection noise reduction methods, which often result in instantaneous exhaust gas pressure blockage and explosion accidents. ThereforeValve exhaust mufflerIt has always been a design challenge, and alsoValve silencerReasons for poor noise reduction effect.

IIValve exhaustsilencerprinciple

        My factoryValve exhaust mufflerThe noise reduction principle of resistance, spray, and resistance is also adopted, in which large hole expansion control is used instead of small hole control to ensure structural stabilityvalveThe principle that door exhaust must be smooth,Further strengthening the principle of resistive noise reductionairflowSound waves enter countless small holes in porous sound-absorbing materials, exciting molecular vibrations in the porous material and converting sound energy into thermal energy to overcome frictional resistance and viscous forces, achieving the desired soundproofing effect and ensuring greater stabilityairflowsmoothlyExhaust out。

IIIValve exhaustsilencerOrder selection

       Produced by our factorysilencerCarefully designed according to the user's emission targets and requirements, only products that match the emission targets and parameters can be obtainedgoodThe noise reduction effect, therefore, when orderingsilencerThe following information must be provided:

      （1）valveWhat is the exhaust volume:(T/h)（m³/h）

（2）What is the starting pressure:(Mpa)(bar)（Kpa）（pa）

（3）temperature:（℃）

（4）Outer diameter and wall thickness of exhaust pipe;For example: Φ159*6
