Description

Technical Field

[0001] The present invention relates to the technical field of valve detection, and in particular to a testing system. Background Art

[0002] In the valve manufacturing industry, newly produced valve products need to be tested for sealing performance. Only valves that pass the sealing performance test are qualified products.

[0003] Valves come in a variety of types, some of which, such as soft-seat ball valves, are used in harsh environments. Soft-seat ball valves are often used in oil and gas pipeline construction due to their excellent sealing performance and cost-effectiveness. However, during construction and operation, they can be damaged by sand and gravel particles, mud mixtures, coke residue, and rust particles within the pipeline, which can affect project progress. Therefore, sealing performance testing is necessary for valves suitable for harsh operating conditions.

[0004] However, the current valve sealing performance test only focuses on the sealing performance of the valve itself, without considering the various harsh working conditions that the valve may encounter during use, resulting in low test accuracy. Summary of the Invention
