Valve detection equipment tells you that the valve needs to be continuously opened and closed during use. The opening and closing of the valve are usually completed by rotating the handwheel or motor, so the rotational torque of the valve has become an important indicator of valve performance testing. The following will introduce the testing method and related precautions for the rotational torque of valve detection equipment.
Firstly, rotational torque refers to the required torque value on a given shaft, usually measured in Newton meters (Nm). In valve detection equipment, torque sensors or torque meters are usually used for rotational torque testing. During testing, fix the valve on the testing machine and apply a fixed external force to the valve. Rotate the handwheel or motor to make the valve move, and record the torque value applied at this time. Calculate the average rotational torque required for the valve to open and close.
When conducting valve rotation torque testing, attention should be paid to the following aspects:
During the testing process, it is necessary to ensure that the torque value applied during testing is stable. The stability of the test can be ensured by checking whether the connection between the valve and the testing machine is firm.
2. It is necessary to select the corresponding testing equipment and methods based on the valve type and specifications to ensure the accuracy of the testing.
During testing, the instruments used, raw data, and analysis results should be recorded for review.
4. It is necessary to analyze and compare the test data to determine whether the performance of the valve meets the standard requirements.
In summary, valve rotation torque testing is an important testing content in valve inspection equipment, which can help determine the working performance and reliability of valves, and provide better valve selection for various industries. During the testing process, attention should be paid to the stability and accuracy of the test in order to obtain reliable test results.
