Regulator is different situation of noise problem solution 1) Series muffler method of this law shall be applicable to the aerodynamic noise, it can effectively eliminate the noise of the fluid inside and control the noise level of transferred to the solid boundary layer. The high mass flow rate or high pressure drop ratio before and after the Industrial Valves, this law is the most effective and economic. Using absorption type series muffler can greatly reduce the noise. From economic considerations, however, generally limited to decay to about 25 decibels. 2) Soundproof box method using soundproof box, houses and buildings, isolating noise inside, reduce the noise of the external environment that people can accept range. 3) Choose low noise low noise valves according to the fluid by regulating valve Industrial Valves core and valve seat tortuous flow ( Hole, slot) Slow down gradually, in order to avoid in any point of the supersonic flow. Have a variety of forms, a variety of low noise of the structure of valve ( For specific system design) When used for selection. When the noise is not very big, choose low noise sleeve valve, can reduce noise 10 ~ 20 db, this is the most economical low noise valve. 4) Series throttle method than the pressure of the regulator is high ( △P / P1≥0。 8) Situations, using the method of series throttle, is to spread out the total pressure drop after the regulator and valve throttling element. If use diffuser, porous current limit board, that is the most effective way to reduce noise. In order to get the best diffuser efficiency, must be installed according to each situation to design the diffuser ( The shape of the entity, size) The noise level, make the Industrial Valves and the noise level of the same diffuser.
