Description

Technical Field

[0001] The present invention relates to the technical field of safety monitoring systems for pressure vessels, and in particular to a high-pressure liquid storage level monitoring device with a linkage alarm structure. Background Art

[0002] Pressurized liquefaction is a commonly used method for storing gas. It utilizes the property that some room-temperature gases can be liquefied under a certain pressure. By pressurizing the gas, room-temperature gas can be liquefied and stored in a pressure vessel, thereby greatly reducing the storage space of the gas.

[0003] Existing pressure vessel safety protection systems usually use multiple devices such as pressure sensors and gas detectors to work together, and evaluate and judge the safety status of pressure vessels through the summarized data; among them, the liquid level sensor placed in the pressure vessel is also a safety protection device. At the same time, the liquid level sensor can also monitor the material reserves in the container; liquefied gas has the characteristic of liquefying under a certain pressure, so when the critical pressure is maintained in the pressure vessel, as the injected gas increases or decreases, the liquid level of the liquefied material therein will also change and rise accordingly. At this time, it is necessary to use liquid level sensors for data detection and early warning, and traditional liquid level sensors use multiple groups of sensors set from top to bottom on the inner wall of the pressure vessel to achieve data monitoring, which makes the sensitivity of sensor monitoring and early warning vary depending on the number of sensors arranged. For this reason, it is now necessary to design a liquid level monitoring device with high sensitivity that can be adjusted according to actual conditions. Summary of the Invention
