Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of valve, especially to a marine quick closing valve for real-time monitoring of leakage. BACKGROUND

[0002] The quick closing valve is a control valve for pipeline system, which has the characteristics of quick closing, and is used on some pipelines of the ship. In the event of an emergency, the quick closing valve can be quickly closed in an emergency to prevent liquid leakage and overflow, thereby ensuring the safety of the ship and the environment.

[0003] In the prior art, when the quick closing valve is used in the pipeline of the ship, the sealing ring at the flange connection part will gradually age due to factors such as continuous pressure bearing, temperature fluctuation and medium corrosion during long-term operation of the valve. This will cause the sealing performance of the flange connection part to decrease, and further cause leakage problems. However, the amount of liquid leaked at the initial leakage position is extremely small. If the liquid flow detection means is simply relied on, it is difficult to accurately capture this abnormal signal due to the too subtle change in flow, resulting in a significant reduction in detection effect. If it is not discovered and handled in time, the leakage condition will continue to deteriorate, causing great loss to the safe operation of the ship. SUMMARY
