Solving the vibration problem of ball valves!
Thread Content
The unit is heated by steam, and Hualin cut-off ball valves are used for steam discharge. Both a cut-off ball valve and a full-function control valve are installed in the steam discharge pipeline; during operation, the control valve is kept fully open, and when steam discharge is needed, the cut-off ball valve is simply opened. Problem: The pipeline vibrates severely! I’m not sure if this situation makes it unsuitable to use a cut-off ball valve; one can only slowly open it using a manual valve! ! Someone with expertise can give some advice! ! Temperature: 200° Pressure: 1.0Mpa
Installing it in this way will certainly cause vibration; the opening degree is too large, and there is an issue with the sequence of operation – the ball valve should be opened first, followed by gradually opening the control valve.
The sequence for switching is designed to first open the ball valve, and then gradually open the control valve! This is much better! For convenience, the operators always slowly open the control valve before opening the ball valve; after communicating with the workshop, it was made clear that operations must be carried out in strict accordance with the process requirements! !
