Description

Technical Field

[0001] This utility model relates to the field of valve testing technology, specifically to a portable valve testing device. Background Technology

[0002] Gas extraction and refining are core components of the oil and gas industry. In the refining process, hydrogen is used extensively in various processes as an important reaction medium to improve oil quality and production efficiency.

[0003] Due to the high pressure, flammability, explosiveness, and permeability of hydrogen, the reliability and operational accuracy of related pipelines and valves are crucial, thus requiring relevant testing of hydrogenation ball valves.

[0004] Hydrogenation ball valves need to operate under high pressure for extended periods. Factors such as friction between the valve seat and the valve ball, and packing seal resistance can cause an abnormal increase in operating torque. If the torque exceeds the limit, it may lead to problems such as valve stem breakage, seal failure, or actuator overload, resulting in hydrogen leakage or even an explosion.

[0005] The fully open or fully closed position of the ball valve must also be precisely controlled. Angle deviation will cause the valve to not be completely sealed or to be over-tightened. The former will cause gas leakage, and the latter will accelerate valve wear.

[0006] In existing technologies, torque and rotation angle are often detected offline or by manual experience. Offline detection requires disassembling the valve and sending it to a relevant laboratory for testing with a torque tester or angle encoder. This method cannot be performed on-site and will seriously affect production efficiency and continuity. Manual detection, on the other hand, involves operators feeling the torque resistance with a wrench or visually estimating the valve opening. This method is too subjective and cannot guarantee the reliability of the data.

[0007] Based on this, the present invention designs a portable valve testing device to solve the above problems. Utility Model Content
