Valve leakage detection

The action of valves can affect the flow of fluids in the system. Leakage or failure of valves can have a significant potential impact on product quality, system safety, and energy consumption.UE SystemsThe ultrasonic testing technology can be applied to most valve leakage detection, such as regulating valves, on-off valves, safety valves, etc. useUltraprobeThe series of ultrasonic instruments can detect the working status of running valves, find internal leaks, and troubleshoot valve faults.

The principle of ultrasonic technology for valve testing

When fluid flows from the high-pressure side of the valve to the low-pressure side through the valve body, turbulence is generated; Turbulence generates ultrasonic signals. And ultrasonic testing instruments can detect the ultrasonic signals generated by turbulence through probes, and convert the ultrasonic signals into audible sound for the human ear through the "heterodyne method". The sound can be listened to through headphones, and the strength of the signal can be seen on the display screen（dBValue).

By adjusting the frequency and sensitivity of the instrument's reception, the impact of fluid viscosity and pipeline system noise can be reduced. Ultrasonic waveform analysis software can also provide a spectrum of ultrasonic signals to assist in determining the state of fluid operation.

Methods for detecting valve internal leakage

Different types of valves require different testing methods. Therefore, before testing a valve, it is necessary to first understand the condition of the fluid system in which the valve is located, the working mode and basic principles of the valve, such as whether the valve belongs to a "normally closed valve" or a "normally open valve".

Determine valve leakage or blockage（ATheBTheCTheDFour point method):

useUltraprobeSeries of ultrasonic instruments, using contact probes with frequency adjusted to25kHz(If it is a model that can adjust the detection frequency). By adjusting the detection sensitivity, detect upstream and downstream of the valve separatelyATheBandCTheDThe readings of four points. Compare the above values to determine whether the valve has internal leakage or blockage. It is also possible to detect readings outside of the four pointsABefore clicking orDAfter clicking, test one more point and determine whether there is interference from upstream and downstream noise by reading.
