Valves are widely used in industries such as industry, energy, chemical industry, petroleum, and natural gas, so the detection of their sealing performance is crucial. As a key component in the pipeline system, the sealing performance of the valve is directly related to the safe operation of the entire system. Therefore, detecting the air tightness leakage of valves is an important measure to ensure the safety of the system. Valve leakage may cause harmful substances to leak into the environment, causing harm to the ecological environment and human health. By detecting the air tightness leakage of valves, the impact on the environment can be reduced and the ecological environment can be protected. Valve leakage will lead to waste of resources such as energy and raw materials, and will also increase energy consumption and production costs. By timely discovering and repairing leakage problems, resources can be effectively saved and production costs can be reduced.
