Valve exhaustmuffler

One:valveexhaustmufflerUsage and advantages

   Valve exhaustmufflerMainly used in power plants, chemical industry, and steel industry、Thermal power, cement, air separation, air compressorSafety valves and exhaust valves in the industrygasEffective noise reduction through emissions. Generally divided：Boiler drum safety valve exhaust muffler、Superheater safety valve exhaust muffler、Reheater safety valve exhaust muffler、Boiler ignition valve exhaust muffler and other valve exhaust mufflers。

    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. designvalveThe exhaust muffler should consider the following three aspects:

       1The noise reduction capacity of the muffler can meet the requirements of the "Industrial Enterprise Noise Health Standards"; 

       2Mufflers should not only avoid excessive noise, but also allow airflow to be smoothly eliminated.

       3The structural performance of the muffler. (Reasonable size, low cost, long service life, etc.) 

Some manufacturers use common multi-stage throttling and small hole injection noise reduction methods to reduce noiseAn explosion and explosion accident occurred due to the instantaneous lack of steam exhaust and pressure. ThereforeValve exhaustSilencers have always been a design challenge, and alsovalveThe reason for the poor noise reduction effect of the muffler.

        My factoryValve exhaustThe muffler also adopts the principle of anti noise, spray noise, and resistance noise reduction, 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。

IIIvalveexhaustmufflerOrder selection

       The mufflers produced by our factory are carefully designed according to the user's emission targets and requirements. Therefore, only products that match the emission targets and parameters can be obtainedgoodTherefore, when ordering a muffler, the following information must be provided:

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

（2）Starting pressurehow much:(Mpa)(bar)（Kpa）（pa）

（3）temperature:（℃）

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