How can vibration of control valves be reduced? Can installing flow-limiting orifice plates help to reduce the vibration of control valves?
Using a flow-limiting orifice plate can reduce the vibration of the control valve, but it also reduces the flow capacity. It is better to find a solution by modifying the valve itself
1. Brackets can be added at both ends of the control valve. 2. Noise reduction panels can also be installed on the process pipelines to reduce vibrations
Installing a flow-limiting orifice plate increases energy consumption! Personally, I think it would be better to use a valve that can handle high pressure differences, such as a corner valve! ! Let’s add the trellis first and see! !
There isn’t a very good solution. Try adding a support to the pipeline to see if that helps; if it doesn’t work, then look for solutions by adjusting the valves
First, it is necessary to analyze and identify the cause of the vibration. If it is caused by pipeline vibration, then pipeline supports should be added and fixed to the pipe sections before and after the control valve. If valve vibration is caused by cavitation behind the valve due to an excessive pressure difference before and after it, then it is necessary to work together with the process team to analyze whether the process parameters are appropriate. By changing the valve size or the structure of the valve core, cavitation can be reduced or eliminated, thereby reducing valve vibration.
Adjust the opening degrees of the manual valves before and after the control valve
If vibration is caused by an excessive pressure difference, it is possible to consider using orifice plates to reduce the pressure difference on the valve; however, the size of the orifices needs to be calculated, and a professional manufacturer can be consulted for this purpose
