Pneumatic control valve components of the noise problem

In gas flow rate on test and adjust the location, and other production equipment related to the compressed air in place, namely those who have different pressure and different gas flow through the place, are generally need to install the regulating valve.And it is these install valve in the gas pipeline will bring to people and the surrounding environment noise pollution.Therefore, must be reduced and the noise.This important environmental noise work not only in the design of new equipment, new factory need to pay attention to, and the existing equipment of the production process must also be addressed.In this paper, a technically feasible and advantageous to the noise of the ecological environmental protection solutions.
Practice has proved that if the factory planning design is take the corresponding measures to solve chemical companies work with noise pollution is the biggest and the most economic.Because the factory design of reduce noise measures Shi is not "remedial" technical conditions (for secondary noise reduction remedy: restricted by the original design, the size of the space limit, etc.), but also there will be no additional expenses.In principle, it is recommended to reduce the noise impact on the environment should be in accordance with the effectiveness and economy is divided into different grades, different measures to deal with.
In order to limit the regulator noises, the manufacturer offers a variety of solutions.What kind of design in the factory when practical application is the most effective to reduce noise and see instance, presented in this paper.For those already in the chemical process equipment used in the regulator, also can be used in this paper, the methods to reduce noise.
Only when the technical measures to control noise on the acoustic control technology is no longer the optimal scheme of technology and economy, people only use the second set of "combat" plan: to control the noise from the noise source in foreign, the so-called "secondary noise source control.This kind of control method of secondary noise is:
S pipe silencer
S pipe sound insulation
S solid sound transmission coupling
S block or closed
In order to choose economic and effective measures to reduce noise, noise must be done, the acoustic intensity noise source in the measurement, and most of the time the sound source is not the noise of the main sound source, namely is not regulating valve of gas pipeline, but some sound surfaces (such as long pipes, cooler), especially in their surface area is much larger than the main noise source.
