The state monitoring and fault diagnosis
1, bonnet temperature detection
(Such as temperature, pressure), according to the recorded temperature changes, analysis of valve operating conditions, life expectancy, reasonable arrangements for maintenance time. In addition, the valve operating conditions, such as temperature and pressure.
2, the valve running sound detection
With auscultation and other tools to monitor the movement of the valve valve and the same level of the same name valve, easy to distinguish the abnormal operation of the valve, according to arrange maintenance.
3, analysis of process parameters changes
Once the valve leaks, it will cause changes in temperature, pressure or flow. You can change the parameters of these parameters to analyze which one valve or even a valve failure.
