Solenoid valve noise elimination method

When we use solenoid valves, the noise produced during work is particularly annoying and depressing. What are some ways to reduce noise? The following are some of the common ways to eliminate noise reduction as summarized by the Lidian valve industry.
First, choose to use a low-noise solenoid valve
There is a low-noise electromagnetic valve specially manufactured for noise reduction in the market. Some of these solenoid valves are used to achieve a purpose of gradually reducing the fluid velocity in a zigzag line in the valve core and the valve seat of the electromagnetic valve, so that the flow path can be avoided. Supersonic speeds anywhere. There is also a direct selection of low-noise sleeve valves, which can reduce the noise of a dozen decibels, which is a relatively common and economical low-noise valve category.
Second, the use of sound-absorbing materials
This method is very simple, is the use of sound-absorbing materials to wrap the device. This method is very common and effective for noiseless situations, but it has to be expensive, especially when the pipeline is very long. It should be noted that the noise will spread with fluid circulation, which is why this method is very expensive.
Third, the use of sound insulation box
This approach is to isolate the noise source with a soundproof box or a house or the like to reduce noise.
Fourth, the use of thick-walled pipelines
The thickness of the general pipeline also determines the size of the noise. The thin wall can eliminate about 5 decibels, and the thick-wall can reduce 20 decibels. The thickness of the pipe wall and the size of the pipe diameter are proportional to the noise reduction effect.
V. Tandem throttling
The so-called serial throttling means that the total pressure drop is distributed to each component. For better efficiency of the diffuser, a detailed understanding of the installation situation is required. The diffuser is designed according to the conditions such as the shape and size of the entity, which can make the electromagnetic Valve noise and diffuser noise levels are the same. Using a diffuser is also the most effective way to reduce noise.
This article describes the five kinds of common noise reduction solenoid valve needs to be effectively selected according to different operating conditions, need to consider the application, practical convenience, cost and other issues. I believe that as long as these factors are fully taken into account and a suitable method is chosen, the elimination of noise from the solenoid valve is not a problem.
