Motor operated valve analysis and testing system with monitoring of spring pack movement through side by side monitoring device |
摘要 |
A system for measuring the operating characteristics of a valve and its operator and the corresponding imposed valve stem load is attached to the valve operator. A unique device and method are used to detect and measure movement of a valve operator spring pack to which access is had from the side of the spring pack. The invention provides initial dynamic traces after initial assembly, maintenance and/or periodic testing of the operator and valve. The invention is then used to provide diagnostic dynamic traces at any specified time in the future for the operator and valve. These future traces are used to compare with earlier traces to verify correct performance and most importantly to detect induced or impending damage, malfunctions, or maintenance requirements for the operator and valve.
