How to control the noise of electric ball valve?
For ball valves, their main functions are similar, but the differences are slight differences in properties and materials. Among many ball valves, electric ball valve is an important product. Its appearance is really helpful to production and safety. Now let’s take a look at the working principle and function of this ball valve. The electric ball valve is mainly driven by electricity, and the whole operation process is also very important. What is the noise control method of electric ball valve? Let’s take a look.
1. Use silencer
A muffler is installed directly downstream of the control valve to effectively reduce the noise of the control valve. The electric ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Among them, the hard seal V-type ball valve has strong shear force, and is especially suitable for fiber, small solid materials and other media. However, some problems often occur when using muffler. If the muffler is useful, it needs a low flow. However, the low flow rate often makes the muffler seem to have no practical value, especially in the large flow system. Secondly, sound elements often do not match the fluid medium. Third, the operating conditions may be poor.
2. Sign of progress pipeline
Increasing the thickness of the pipe wall can reduce the noise of the electric ball valve. However, once sound occurs, it cannot be flexibly propagated along the length of the dirty pipe, so this method usually needs to be used in the whole system.
3. Pipeline isolation method
This method is the same as adding the thickness of the pipe wall and can also be used to reduce the declared noise. However, it is necessary to pay attention to three constraints. The whole downstream system also needs to adopt the same method as changing the number of pipes. Secondly, it is necessary to carefully install the isolated data to prevent the data from being “invalid”, which will seriously reduce the practicability of the method. Third, it is usually used for the insulation of piping systems, and its usefulness in reducing noise is limited. Since correct information is usually not suitable for high temperatures, the adhesive used may melt, fundamentally changing its acoustic quality and thermal characteristics.
